This issue becomes critical in environments where auditory awareness—such as responding to verbal instructions or localizing alarms—is essential for performance and safety. While head-mounted displays have demonstrated potential in enhancing situational awareness through visual cues, their effectiveness in supporting sound localization under the influence of circadian fatigue remains under-explored. This study addresses this knowledge gap through a longitudinal study (N=19) conducted over 2–4 months, tracking participants’ fatigue levels through daily assessments. Participants were called in to perform non-line-of-sight sound source identification and localization tasks in a virtual environment under high- and low-fatigue conditions, both with and without head-up display assistance. The results show task-dependent effects of circadian fatigue. Unexpectedly, reaction times were shorter across all tasks under high-fatigue conditions. Yet, in sound localization, where precision is key, the HUD offered the greatest performance enhancement by reducing pointing error. The results suggest the auditory channel is a robust means of enhancing situational awareness and providing support for incorporating spatial audio cues and HUD as standard features in augmented reality platforms for fatigue-prone scenarios.\r\n","authors":[{"affiliations":[{"country":"Australia","state":"New South Wales","city":"Sydney","institution":"University of Technology Sydney","dsl":"School of Computer Science, FEIT"}],"personId":183016},{"affiliations":[{"country":"Australia","state":"New South Wales","city":"Camperdown","institution":"University of Sydney","dsl":"Discipline of Design"},{"country":"Australia","state":"NSW","city":"Sydney","institution":"University of Technology Sydney","dsl":"School of Computer Science"}],"personId":184191},{"affiliations":[{"country":"Australia","state":"South Australia","city":"Adelaide","institution":"University of Adelaide","dsl":"School of Computer and Mathematical Sciences"}],"personId":183141},{"affiliations":[{"country":"Australia","state":"NSW","city":"Sydney","institution":"University of Technology Sydney","dsl":""}],"personId":183940},{"affiliations":[{"country":"Australia","state":"NSW","city":"Sydney","institution":"University of Technology Sydney","dsl":"School of Computer Science, FEIT"}],"personId":182903},{"affiliations":[{"country":"United States","state":"New Jersey","city":"Cherry Hill","institution":"Lockheed Martin","dsl":"Advanced Technology Laboratories"}],"personId":185369},{"affiliations":[{"country":"United States","state":"Virginia","city":"Arlington","institution":"Lockheed Martin","dsl":""}],"personId":187320},{"affiliations":[{"country":"United States","state":"New Jersey","city":"Cherry Hill","institution":"Lockheed Martin","dsl":"Advance Technology Laboratories"}],"personId":184214},{"affiliations":[{"country":"United States","state":"Virginia","city":"Arlington","institution":"Lockheed Martin","dsl":""}],"personId":186414},{"affiliations":[{"country":"Australia","state":"","city":"Ultimo","institution":"Australian AI Institute, School of Computer Science, Faculty of Engineering and Information Technology, University of Technology Sydney","dsl":""}],"personId":187896}]},{"id":188223,"typeId":13945,"title":"PAIRcolator: Pair Collaboration for Sensemaking and Reflection on Personal Data","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713332"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=971FseJJdE8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8210","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195107],"eventIds":[],"abstract":"This paper explores pair collaboration as a novel approach for making sense of personal data.

Opinions shared on social media have different sentiments associated with them. Given the very high adoption rates of X (formerly known as Twitter) among adults, those who share their opinions on X not only represent a sizable segment of the society, but also influence (through emotion contagion) an even larger segment who are passive (non-contributing) users of the platform. Furthermore, the discourse that is initiated on X typically spreads to other more traditional media. As a result, X is influential, which makes it useful to understand the factors related to the sentiments expressed in tweets. Such understanding can help policymakers to take actions that align with public needs and priorities. This research focuses on identifying the drivers (keywords) of sentiments associated with political discourse on X. We also explore virality, i.e., how much a message (the tweet) spreads, and the relationship between sentiments and virality. Finally, we explore whether the clustering of tweets among sentiment and virality groups can improve the potential of social media content for predicting election results. Sentiment Analysis of 764,000 tweets related to the 2021 Canadian Federal election was followed by text clustering to identify sentiment-driving topics. We found some keywords predominantly present within a positive or negative sentiment that are suggestive of entities or ideas to invest in or mitigate by political decision makers. We were also able to find partial evidence for “negativity bias” by detecting a negative relationship between sentiment (positivity) and virality (number of retweets). Finally, we demonstrated that high positivity on the political discourse does not reflect election outcomes and examining X content in more neutral groups can improve predictive power.

While prior work focused on avatar-related factors influencing the noticeability of redirection, we investigate how the visual stimuli in the surrounding virtual environment affect user behavior and, in turn, the noticeability of redirection. Given the wide variety of different types of visual stimuli and their tendency to elicit varying individual reactions, we propose to use users' gaze behavior as an indicator of their response to the stimuli and model the noticeability of redirection. We conducted two user studies to collect users' gaze behavior and noticeability, investigating the relationship between them and identifying the most effective gaze behavior features for predicting noticeability. Based on the data, we developed a regression model that takes users' gaze behavior as input and outputs the noticeability of redirection. We then conducted an evaluation study to test our model on unseen visual stimuli, achieving an accuracy of 0.012 MSE. We further implemented an adaptive redirection technique and conducted a proof-of-concept study to evaluate its effectiveness with complex visual stimuli in two applications. The results indicated that participants experienced less physical demanding and a stronger sense of body ownership when using our adaptive technique, demonstrating the potential of our model to support real-world use cases.","authors":[{"affiliations":[{"country":"Switzerland","state":"","city":"Zurich","institution":"ETH Zurich","dsl":"Department of Computer Science"}],"personId":187140},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":""}],"personId":185286},{"affiliations":[{"country":"United States","state":"Wisconsin","city":"Madison","institution":"University of Wisconsin-Madison","dsl":""}],"personId":186880},{"affiliations":[{"country":"United States","state":"New York","city":"Ithaca","institution":"Cornell University","dsl":"Department of Information Science"}],"personId":185605},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Tsinghua University","dsl":"Department of Computer Science and Technology"}],"personId":183231},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Tsinghua University","dsl":"Department of Computer science and Technology"}],"personId":187044},{"affiliations":[{"country":"United States","state":"New York","city":"Rochester","institution":"University of Rochester","dsl":"Department of Computer Science"}],"personId":182990}]},{"id":188263,"typeId":13945,"title":"Private Yet Social: How LLM Chatbots Support and Challenge Eating Disorder Recovery","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713485"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=eUKD5Sb6ytc"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8434","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195081],"eventIds":[],"abstract":"Eating disorders (ED) are complex mental health conditions that require long-term management and support.

In this work, we experimentally evaluate whether online advertisers target people with health conditions. We collected the browsing histories of people with and without health conditions. We crawled their histories to simulate their browsing profiles and collected the ads that were served to them. Then, we compared the content of the ads between groups. We observed that the profiles of people who visited more health-related web pages received more health-related ads. 49.5% of health-related ads used deceptive advertising techniques.

Furthermore, we also found that the VTuber community is increasingly monopolized by two agencies, driving the financial disparity. This research illuminates the financial dynamics of VTuber communities, informing the design of equitable platforms and sustainable support systems for digital content creators.","authors":[{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"University of British Columbia","dsl":""}],"personId":186489},{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"University of British Columbia","dsl":""}],"personId":184130},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":183084},{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"University of British Columbia","dsl":"Computer Science"}],"personId":185035},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":186784},{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"University of British Columbia","dsl":"Department of Linguistics"}],"personId":186835}]},{"id":188289,"typeId":13945,"title":"TH-Wood: Developing Thermo-Hygro-Coordinating Driven Wood Actuators to Enhance Human-Nature Interaction","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714304"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=A5E4IWbAoKU"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9530","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195095],"eventIds":[],"abstract":"Wood has become increasingly applied in shape-changing interfaces for its eco-friendly and smart responsive properties, while its applications face challenges as it remains primarily driven by humidity.

Nevertheless, only some studies describe how to get or support pupils to learn to regulate group work in school. In this context, we aim to understand if a specifically designed tangible environment can promote a regulated collaboration process during a face-to-face activity in school. Therefore, we conducted a 2-year design-based research (DBR) study. This article describes the DBR cycles in detail, and the steps we have executed to develop, test, implement, and evaluate a set of tangible artifacts called Collective attention led by a Mediated environment (CalMe). First, we identified three specific dimensions that interfere with CL in the classroom: team building and collective decision-making, task regulation awareness, and over-solicitation limitation. Second, we proposed design choices leading to the first iteration of a CalMe device that meets these needs. We then assessed usability and acceptability before the pedagogical validation steps. Third, through a pilot study, we evaluated the pedagogical potential of the second iteration of the CalMe device in a real context of use in an elementary school class. We collected and analyzed data from surveys, focus groups, log data, and video recordings through all the steps. Moreover, to allow for duplication of the study, we propose and detail our methodological approach. This study shows an empirical example of a DBR process that allows responding as closely as possible to the needs of both pupils and teachers.

We conclude by proposing that designers not only bear the responsibility of grappling critically with the complexities of AI but also possess the opportunity to creatively harness the limitations of technology to craft a reflexive data curation that encourages profound reflections and awareness within design processes.","authors":[{"affiliations":[{"country":"Netherlands","state":"","city":"Netherlands","institution":"Delft University of Technology","dsl":"Web Information Systems"}],"personId":185343},{"affiliations":[{"country":"Italy","state":"","city":"Turin","institution":"Politecnico di Torino ","dsl":"Department of Architecture and Design "}],"personId":183956},{"affiliations":[{"country":"Italy","state":"","city":"Milano","institution":"Politecnico di Milano","dsl":"Department of Design"}],"personId":186915}]},{"id":188331,"typeId":14039,"title":"Self-Determination Theory and HCI Games Research: Unfulfilled Promises and Unquestioned Paradigms","addons":{"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=0QQ5GmAKXpg"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25s-1013","source":"PCS","trackId":13414,"tags":[],"keywords":[],"sessionIds":[191705],"eventIds":[],"abstract":"Self-determination theory (SDT), a psychological theory of human motivation, is a prominent paradigm in human–computer interaction (HCI) research on games. However, our prior literature review observed a trend towards shallow applications of the theory. This follow-up work takes a broader view—examining SDT scholarship on games, a wider corpus of SDT-based HCI games research (N = 259), and perspectives from a games industry practitioner conference—to help explain current applications of SDT. Our findings suggest that perfunctory applications of the theory in HCI games research originate in part from within SDT scholarship on games, which itself exhibits limited engagement with theoretical tenets. Against this backdrop, we unpack the popularity of SDT in HCI games research and identify conditions underlying the theory’s current use as an oft-unquestioned paradigm. Finally, we outline avenues for more productive SDT-informed games research and consider ways towards more intentional practices of theory use in HCI.","authors":[{"affiliations":[{"country":"Denmark","state":"","city":"Copenhagen","institution":"IT University of Copenhagen","dsl":""}],"personId":183723},{"affiliations":[{"country":"Denmark","state":"","city":"Copenhagen","institution":"IT University of Copenhagen","dsl":"Digital Design"}],"personId":182888}]},{"id":188332,"typeId":13940,"title":"Conversational Voice Interfaces: Translating Research Into Actionable Design","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3716395"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25k-1046","source":"PCS","trackId":13418,"tags":[],"keywords":[],"sessionIds":[190037],"eventIds":[],"abstract":"HCI research has for long been dedicated to better and more nat- urally facilitating information transfer between humans and ma- chines. Unfortunately, humans’ most natural form of communi- cation, speech, is also one of the most difficult modalities to be understood by machines – despite, and perhaps, because it is the highest-bandwidth communication channel we possess. As signifi- cant research efforts in engineering have been spent on improving machines’ ability to understand speech, research is only begin- ning to make the same improvements in understanding how to appropriately design these speech interfaces to be user-friendly and adoptable. Issues such as variations in error rates when pro- cessing speech, and difficulties in learnability and explainability (to name a few), are often in contrast with claims of success from industry. Along with this, designers themselves are making the transition to designing for speech and voice-enabled interfaces. Recent research has demonstrated the struggle for designers to translate their current experiences in graphical user interface de- sign into speech interface design. Research has also noted the lack of any user-centered design principles or consideration for usability or usefulness in the same ways as graphical user interfaces have benefited from heuristic design guidelines.\r\nThe goal of this course is to inform the CHI community of the current state of speech and natural language research, to dispel some of the myths surrounding speech-based interaction, as well as to inform participants about currently existing design tools, meth- ods and resources for speech interfaces (and provide hands-on experience with working with them). Through this, we hope that HCI researchers and practitioners will learn how to combine re- cent advances in speech processing with user-centred principles in designing more usable and useful speech-based interactive systems.","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":""},{"country":"Canada","state":"Ontario","city":"Ottawa","institution":"Carleton University","dsl":""}],"personId":186392},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"Department of Systems Design Engineering"},{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"Technologies for Ageing Gracefully"}],"personId":184131},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"Dept. of Computer Science"}],"personId":185558}]},{"id":188333,"typeId":14039,"title":"Why Larp?

Through interviews, we found that these collaborative tasks require coordination work that is not materialized in existing management tools. We also found that requesters are willing to take on this coordination work to see their requests fulfilled. To address this issue, we propose a system called TaskLight, which allows requesters to handle coordination work themselves. For example, requesters can collect useful context and information for their performers. We conducted two deployment studies and found that TaskLight leads to better outcomes because requesters are able to assist performers more effectively.

ML researchers and philosophers posit that multiplicity poses a fairness risk, but no studies have investigated whether stakeholders agree. In this work, we conduct a survey to see how multiplicity impacts lay stakeholders’ – i.e., decision subjects’ – perceptions of ML fairness, and which approaches to address multiplicity they prefer. We investigate how these perceptions are modulated by task characteristics (e.g., stakes and uncertainty). Survey respondents think that multiplicity threatens the fairness of model outcomes, but not the appropriateness of using the model, even though existing work suggests the opposite. Participants are strongly against resolving multiplicity by using a single model (effectively ignoring multiplicity) or by randomizing the outcomes. Our results indicate that model developers should be intentional about dealing with multiplicity in order to maintain fairness.","authors":[{"affiliations":[{"country":"United States","state":"Wisconsin","city":"Madison","institution":"University of Wisconsin - Madison","dsl":""}],"personId":187829},{"affiliations":[{"country":"United States","state":"Colorado","city":"Boulder","institution":"Apple","dsl":""}],"personId":183725},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California - San Diego","dsl":""}],"personId":186965},{"affiliations":[{"country":"United States","state":"Wisconsin","city":"Madison","institution":"University of Wisconsin-Madison","dsl":""}],"personId":183291}]},{"id":188346,"typeId":13945,"title":"How Do People Perceive Bundling?

Femininity, regardless of the queer identities of those who embody it, is devalued and associated with lesser technical competence. Beyond social dynamics, gendered hierarchies influence programming tools, roles, and physical environments, embedding exclusion within technical culture. Although gender-fluid expressions like cosplay provide moments of subversion, they remain limited by the masculine framework of hackathons.

Critically, the option to delay yields this overall increase without reducing the share of people choosing to change their password immediately. Additionally, most participants who promised to change their password later, or asked to be reminded to do so, indeed followed through on their commitment, leading to a net positive effect. Reminding participants of their previous\r\ncommitment further increased this effect.","authors":[{"affiliations":[{"country":"Israel","state":"","city":"Jerusalem","institution":"Hebrew University of Jerusalem","dsl":""}],"personId":185105},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"International Computer Science Institute","dsl":"Usable Privacy and Security Research Group"}],"personId":184763},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"University of California Berkeley","dsl":"EECS"}],"personId":186028},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"International Computer Science Institute","dsl":""},{"country":"United States","state":"California","city":"Berkeley","institution":"University of California","dsl":""}],"personId":183875}]},{"id":188360,"typeId":13940,"title":"UX Research Meets AI: Level Up Your Skills","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3706644"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25k-1038","source":"PCS","trackId":13418,"tags":[],"keywords":[],"sessionIds":[190082],"eventIds":[],"abstract":"This course will empower the attendees to confidently navigate the changing landscape of UX research.

Connecting Barad's quantum view of indeterminacy to the prevailing HCI discourse on the opportunities and challenges of ambiguity, we suggest that the very act of trying to stabilise a conceptual interpretation of data within an artefact has the paradoxical effect of amplifying and shifting ambiguity in interaction. We illustrate these ideas through three case studies from our own practices of designing digital musical instruments (DMIs). DMIs necessarily encode symbolic and music-theoretical knowledge as part of their internal operation, even as conceptual knowledge is not their intended outcome. In each case, we explore the nature of the apparatus, what phenomena it co-produces, and where the ambiguity lies to suggest approaches for design using these abstract theoretical frameworks.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"Loughborough University London","dsl":"Institute for Digital Technologies"}],"personId":184090},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"School of Electronic Engineering and Computer Science","dsl":"Centre for Digital Music"}],"personId":183460},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"Queen Mary University of London","dsl":"Centre for Digital Music"}],"personId":184972},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"Imperial College London","dsl":"Dyson School of Design Engineering"}],"personId":185829}]},{"id":188369,"typeId":14039,"title":"Biodegradation as More-Than-Human Unmaking","addons":{"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=ZdcK7709dP0"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25s-1031","source":"PCS","trackId":13414,"tags":[],"keywords":[],"sessionIds":[191707],"eventIds":[],"abstract":"In this work, we introduce biodegradation as a process of more-than-human unmaking.

Moreover, as the depth and informativeness of reasoning increase, so do the number of tokens required, leading to higher latency and cost.\r\n This study investigates how an LLM-based coaching agent can adjust its reasoning depth using a discrepancy mechanism that signals how much reasoning effort to allocate based on how well the objective is being met.\r\n Our discrepancy-based mechanism constrains reasoning to better align with alternative objectives, reducing cost roughly tenfold while minimally impacting interaction quality.","authors":[{"affiliations":[{"country":"Switzerland","state":"","city":"St.Gallen","institution":"University of St.Gallen","dsl":""}],"personId":188156},{"affiliations":[{"country":"Switzerland","state":"Bern","city":"Bern","institution":"Institute for Digital Technology Management","dsl":""}],"personId":183161},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"University of Pennsylvania","dsl":"Department of Computer and Information Science"}],"personId":185045}]},{"id":188389,"typeId":13945,"title":"Designing LLM-Powered Multimodal Instructions to Support Rich Hands-on Skills Remote Learning: A Case Study with Massage Instructors and Learners","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713677"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=-xBaYj6N2Ek"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7780","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[194996],"eventIds":[],"abstract":"Although remote learning is widely used for delivering and capturing knowledge, it has limitations in teaching hands-on skills that require nuanced instructions and demonstrations of precise actions, such as massage.

To achieve this, we engineered receiver-tags and coils, including thin pancake-coils best-suited for wearables and spherical-coils that receive power omnidirectionally. To understand which coils best support a wide range of interactions (e.g., grasping, touching, hovering), we performed technical characterizations, including impedance and 3D efficiency analysis. We believe our technical approach can inspire ubiquitous computing with new ways to scale up the number and diversity of battery-free devices, not just sensors (µWatts) but also actuators (Watts).","authors":[{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":187744},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":186716},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":182945},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":183578}]},{"id":188414,"typeId":13945,"title":"Enabling Recycling of Multi-Material 3D Printed Objects through Computational Design and Disassembly by Dissolution","award":"BEST_PAPER","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714080"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=wNiyyy-72f8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7792","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195036],"eventIds":[],"abstract":"Multi-material 3D printing combines the functional properties of different materials (e.g., mechanical, electrical, color) within a single object that is fabricated without manual assembly. However, this presents sustainability challenges as multi-material objects cannot be easily recycled. Because each material has a different processing temperature, considerable effort must be used to separate them for recycling. This paper presents a computational fabrication technique to generate dissolvable interfaces between different materials in a 3D printed object without affecting the object’s intended use. When the interfaces are dissolved, the object is disassembled to enable recycling of the individual materials. We describe the computational design of these interfaces alongside experimental evaluations of their strength and water solubility. Finally, we demonstrate our technique across 9 multi-material 3D printed objects of varying structural and functional complexity. Our technique enables us to recycle 89.97% of the total mass of these objects, promoting greater sustainability in 3D printing.","authors":[{"affiliations":[{"country":"United States","state":"Colorado","city":"Boulder","institution":"University of Colorado Boulder","dsl":"ATLAS Institute"}],"personId":184836},{"affiliations":[{"country":"United States","state":"Colorado","city":"Boulder","institution":"University of Colorado Boulder","dsl":"ATLAS Institute"}],"personId":184101},{"affiliations":[{"country":"United States","state":"Colorado","city":"Boulder","institution":"University of Colorado Boulder","dsl":"ATLAS Institute and Department of Computer Science"}],"personId":185742}]},{"id":188415,"typeId":13945,"title":"SmarTeeth: Augmenting Manual Toothbrushing with In-ear Microphones","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713893"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=wPGYvE4IYoI"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-5373","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195041],"eventIds":[],"abstract":"Improper toothbrushing practices persist as a primary cause of oral health issues such as tooth decay and gum disease. Despite the availability of high-end electric toothbrushes that offer some guidance, manual toothbrushes remain widely used due to their simplicity and convenience. We present SmarTeeth, an earable-based toothbrushing monitoring system designed to augment manual toothbrushing with functionalities typically offered only by high-end electric toothbrushes, such as brushing surface tracking. The underlying idea of SmarTeeth is to leverage in-ear microphones on earphones to capture toothbrushing sounds transmitted through the oral cavity to ear canals through facial bones and tissues. The distinct propagation paths of brushing sounds from various dental locations to each ear canal provide the foundational basis for our methods to accurately identify different brushing locations. By extracting customized features from these sounds, we can detect brushing locations using a deep-learning model. With only one registration session (~2 mins) for a new user, the average accuracy is 92.7% for detecting six regions and 75.6% for sixteen tooth surfaces. With three registration sessions (~6 mins), the performance can be boosted to 98.8% and 90.3% for six-region and sixteen-surface tracking, respectively. A key advantage of using earphones for monitoring is that they provide natural auditory feedback to alert users when they are overbrushing or underbrushing. Comprehensive evaluation validates the effectiveness of SmarTeeth under various conditions (different users, brushes, orders, noise, etc.), and the feedback from the user study (N=13) indicates that users found the system highly useful (6.0/7.0) and reported a low workload (2.5/7.0) while using it. Our findings suggest that SmarTeeth could offer a scalable and effective solution to improve oral health globally by providing manual toothbrush users with advanced brushing monitoring capabilities.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"Cambridge","institution":"University of Cambridge","dsl":"Department of Computer Science and Technology"}],"personId":183536},{"affiliations":[{"country":"United Kingdom","state":"","city":"Cambridge","institution":"University of Cambridge","dsl":""}],"personId":182685},{"affiliations":[{"country":"United Kingdom","state":"","city":"Cambridge","institution":"University of Cambridge","dsl":"Computer Laboratory"}],"personId":186217},{"affiliations":[{"country":"United Kingdom","state":"","city":"Cambridge","institution":"University of Cambridge","dsl":"Department of Computer Science and Technology"}],"personId":187043},{"affiliations":[{"country":"United Kingdom","state":"London","city":"London","institution":"King’s College London","dsl":"Faculty of Dentistry,Oral and Craniofacial Sciences"}],"personId":185336},{"affiliations":[{"country":"Singapore","state":"","city":"Singapore","institution":"Singapore Management University","dsl":""}],"personId":182699},{"affiliations":[{"country":"United Kingdom","state":"","city":"Cambridge","institution":"University of Cambridge","dsl":""}],"personId":183855}]},{"id":188416,"typeId":14039,"title":"Classifying Presence Scores: Insights and Analysis from Two Decades of the Igroup Presence Questionnaire (IPQ)","addons":{"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=DL_fj9JBXkc"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25s-1004","source":"PCS","trackId":13414,"tags":[],"keywords":[],"sessionIds":[191705],"eventIds":[],"abstract":"Presence, or the experience of being present in a computer-generated environment, is a defining element of virtual reality.

Building on the idea that uncertainties drive design activity, we describe the design process as framing acts where a designer-researcher moves along perceived uncertainties.

In the past decade, the news ecosystem and information flow have been dramatically trans- formed by the popularity of such platforms. Social media users can, in fact, easily access nearly any kind of information and then spread it nearly without friction through activities such as tweets/retweets in Twitter (now X) and similar means on other social media. This seemingly innocuous activity of spreading information has a collective consequence of making social media users responsible for radical changes in the way news is distributed, including both authentic and fake news. Moreover, malicious individuals have been implicated in capitalizing on the ease of introducing and spreading information in these platforms to create misinformation, spread it to a wider audience, and subsequently influence public opinion on important topics through information diffusion. Therefore, understanding the factors that motivate a user’s decision to share is of paramount importance in understanding the information diffusion phenomenon in social media.\r\nIn this article, we propose an approach based on the Diffusion of Innovation theory to model, characterize, and compare real and fake news sharing in social media with a focus on different levels of influencing factors including innovation, communication channels, and social system. We apply that approach to identify factors related to the spread of fake news as they relate to users, the structure of news items themselves, and the networks through which news is circulated. We address the problem of predicting real and fake news sharing as a classification task and demonstrate the potentials of the proposed features by achieving an AUROC of around 0.97 and an average precision ranging from 0.88 to 0.95, consistently outperforming baseline models with a higher margin (at least 13% of average precision). In addition, we also found out that empirically identifiable characteristics of news items themselves and users who share news are the strongest element allowing accurate prediction of real and fake news sharing, followed by network-based features. Moreover, our proposed approach can be effectively used to model news diffusion as a multi-step propagation process.","authors":[{"affiliations":[{"country":"United States","state":"Idaho","city":"Boise","institution":"Boise State University","dsl":""}],"personId":187036},{"affiliations":[{"country":"United States","state":"Idaho","city":"Boise","institution":"Boise State University","dsl":"Department of Computer Science"}],"personId":186819},{"affiliations":[{"country":"United States","state":"Idaho","city":"Boise","institution":"Boise State University","dsl":""}],"personId":183998},{"affiliations":[{"country":"United States","state":"Idaho","city":"Boise","institution":"Boise State University","dsl":""}],"personId":182798},{"affiliations":[{"country":"United States","state":"Idaho","city":"Boise","institution":"Boise State University","dsl":"Organizational Performance and Workplace Learning"}],"personId":184325}]},{"id":188421,"typeId":13940,"title":"Design Thinking with Generative AI: Powerful ChatGPT Skills for UX","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3706656"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25k-1058","source":"PCS","trackId":13418,"tags":[],"keywords":[],"sessionIds":[190019],"eventIds":[],"abstract":"Generative AI is transforming UX design, and this course expands your design toolkit to leverage ChatGPT and DALL-E to save time and elevate your end-to-end design process.

Using Kenya as a field site, this project aims to examine the tensions emerging in digital credit relationships, paying close attention to the artful work involved in translating and repairing relations and exchanges between digital credit companies and borrowers.\r\n","authors":[{"affiliations":[{"country":"United States","state":"New York","city":"Ithaca","institution":"Cornell University","dsl":"Department of Information Science"}],"personId":187712}]},{"id":188441,"typeId":13945,"title":"Human Creativity in the Age of LLMs: Randomized Experiments on Divergent and Convergent Thinking","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714198"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=lnQf1kG_vk8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9735","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[194997],"eventIds":[],"abstract":"Large language models are transforming the creative process by offering unprecedented capabilities to algorithmically generate ideas.

Through a qualitative study with mutual aid volunteers in the United States, we found that mutual aid groups’ values, such as solidarity, security, and co-production, are prioritized as they navigate adopting technology. However, while technology can streamline logistics and enhance visibility for mutual aid groups, we argue that the adoption of existing technologies and conventions of practice can erode opportunities for building solidarity, present challenges for accountability, and exacerbate pre-existing social exclusions. We argue that these tensions emerge not simply as a mismatch between values and technical design, but as systematic outcomes of adopting tools that embed different political assumptions and points of access.

This study builds on prior work to yield more detailed insights regarding the potential of adopting online restorative justice tools, including opportunities, challenges, and implications for future designs.","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":"School of Computing"}],"personId":183567},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":"School of Computing"}],"personId":185260}]},{"id":188455,"typeId":13945,"title":"Explanatory Debiasing: Involving Domain Experts in the Data Generation Process to Mitigate Representation Bias in AI Systems","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713497"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=mOTwp4yXAwk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-6676","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195148],"eventIds":[],"abstract":"Representation bias is one of the most common types of biases in artificial intelligence (AI) systems, causing AI models to perform poorly on underrepresented data segments.

We instantiated our proposed guidelines in a healthcare-focused application and evaluated them through a comprehensive mixed-methods user study with 35 healthcare experts. Our findings show that involving domain experts can reduce representation bias without compromising model accuracy.

In this study, from a corpus of 10 videos, we present three cases of online and in-person therapy sessions with children between the ages of 3 and 6. Our analysis shows how online and in-person SLT sessions use tools, how they are conscripted into social and transactional moments, and identifies features of tools that support or hinder therapists’ goals (see Figure 1). From our findings, we discuss in detail four overarching features of tools and implications for design. These features support engagement, space usage, child-centred play, and adaptability in therapy sessions. The paper outlines how these features are present in the tools used in SLT, and describes how they impact SLT activities, therapists’ and children’s goals, and the environment for social transactional activities.","authors":[{"affiliations":[{"country":"Australia","state":"Qld","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Australian Research Council Centre of Excellence for the Digital Child"},{"country":"Australia","state":"Qld","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Computer Science"}],"personId":187579},{"affiliations":[{"country":"Australia","state":"QLD","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Australian Research Council Centre of Excellence for the Digital Child"},{"country":"Australia","state":"Qld","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Creative Industries, Education and Social Justice"}],"personId":186055},{"affiliations":[{"country":"Australia","state":"Qld","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Australian Research Council Centre of Excellence for the Digital Child"}],"personId":186001},{"affiliations":[{"country":"Australia","state":"QLD","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Creative Industries Education and Social Justice"},{"country":"Australia","state":"Qld","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Australian Research Council Centre of Excellence for the Digital Child"}],"personId":185964},{"affiliations":[{"country":"Australia","state":"","city":"Sydney","institution":"University of Technology Sydney","dsl":""},{"country":"Australia","state":"Qld","city":"Brisbane","institution":"Queensland University of Technology","dsl":"Australian Research Council Centre of Excellence for the Digital Child"}],"personId":183414}]},{"id":188468,"typeId":13952,"title":"Finding Our Joy: Queer Perspectives on HCI Research","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3716221"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=Cneogt3XvSo"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25i-6624","source":"PCS","trackId":13416,"tags":[],"keywords":[],"sessionIds":[194989],"eventIds":[],"abstract":"How do we make space for joy in Queer HCI?

To address this gap, we introduce PATRIKA, an AI-enabled prototype designed specifically for people with Parkinson's disease (PwPD). The system incorporates cooperative conversation principles, clinical interview simulations, and personalization to create a more effective and user-friendly journaling experience. Through two user studies with PwPD and iterative refinement of PATRIKA, we demonstrate conversational journaling's significant potential in patient engagement and collecting clinically valuable information. Our results showed that generating probing questions PATRIKA turned journaling into a bi-directional interaction.

In a within-subjects study comparing Inkspire to ControlNet, we found that Inkspire supported designers with more inspiration and exploration of design ideas, and improved aspects of the co-creative process by allowing designers to effectively grasp the current state of the AI to guide it towards novel design intentions.","authors":[{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute"}],"personId":183790},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute"}],"personId":184407},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute"}],"personId":182663},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human Computer Interaction Institute"}],"personId":183410},{"affiliations":[{"country":"United States","state":"California","city":"Los Altos","institution":"Toyota Research Institute","dsl":""}],"personId":186009},{"affiliations":[{"country":"United States","state":"California","city":"Los Altos","institution":"Toyota Research Institute","dsl":""}],"personId":184694}]},{"id":188479,"typeId":13945,"title":"PiaMuscle: Improving Piano Skill Acquisition by Cost-effectively Estimating and Visualizing Activities of Miniature Hand Muscles","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713465"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=Kzv1Z_PDoTI"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9959","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195043],"eventIds":[],"abstract":"Understanding neuromusculoskeletal mechanisms significantly impacts skill specialization and proficiency.

We also present a consensus set of sixty gestures for effecting generic commands in interactive systems, along with design principles encompassing multiple practical implications for interactions that incorporate intermanual deictics.","authors":[{"affiliations":[{"country":"Romania","state":"","city":"Suceava","institution":"Ștefan cel Mare University of Suceava","dsl":"MintViz Lab, MANSiD Research Center"}],"personId":184882},{"affiliations":[{"country":"Romania","state":"","city":"Suceava","institution":"Stefan cel Mare University of Suceava","dsl":"MintViz Lab, MANSiD Research Center"}],"personId":187450}]},{"id":188491,"typeId":13945,"title":"Virtual Visits, Real Emotions: Designing Social VR Experiences for Imprisoned Fathers and their Children","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714018"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=ICjodvQZwq4"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-6205","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195142],"eventIds":[],"abstract":"The imprisonment of parents has severe consequences for their relationship to their children.

In this paper, we share findings of a user-centered design process of a virtual reality application that allows imprisoned parents to meet their children. Our pilot study with four dyads of children and imprisoned fathers revealed that both appreciated the virtual visits, felt close to each other, and had a positive emotional experience, although fathers missed physical contact.

For each goal, we examined child-parent roles, data types collected, and features that facilitate or hinder collaboration. Our findings highlight key directions for future research, including designing adaptable technologies to reflect evolving child-parent roles, exploring different technologies and tracking topics that impact child-parent dynamics, involving children in the system design stage to enhance collaborative features, and studying diverse populations with varied family characteristics.

While we often take it for granted, with the adoption of virtual reality (VR) technology, embodiment in virtual bodies and worlds has become an important consideration for designers of immersive experiences. To date, the VR design community has primarily considered embodiment in terms of body ownership over a synchronized visual representation. In this paper, we construct an interactional framework of virtual embodiment, beginning by revisiting what it really means to be “embodied.” Our framework reconnects embodiment and presence in virtual environments founded in Dourish's concept of embodied interaction and Heidegger's Dasein or “being-in-the-world.” We discuss how embodiment, fundamentally rooted in past and present interactions, changes our understanding of body ownership and its extension into VR. Integrating theories from VR research, philosophy, HCI, and psychology we uncover the complex interplay of interaction, environment, and touch in shaping embodied experiences. We present a novel framework for understanding embodiment in VR rooted in interaction, enabling designers to create more immersive and meaningful virtual worlds.","authors":[{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"Simon Fraser University","dsl":"School of Interactive Arts and Technology"}],"personId":188054},{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"Simon Fraser University","dsl":"School of Interactive Arts and Technology"}],"personId":183057},{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Vancouver","institution":"Simon Fraser University","dsl":"School of Interactive Arts + Technology (SIAT)"}],"personId":187657}]},{"id":188548,"typeId":13945,"title":"DBox: Scaffolding Algorithmic Programming Learning through Learner-LLM Co-Decomposition","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713748"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=oZFdFQdcoJ0"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-2271","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195073],"eventIds":[],"abstract":"Decomposition is a fundamental skill in algorithmic programming, requiring learners to break down complex problems into smaller, manageable parts.

To address this, we introduce Decomposition Box (DBox), an interactive LLM-based system that scaffolds and adapts to learners' personalized construction of a step tree through a \"learner-LLM co-decomposition\" approach, providing tailored support at an appropriate level.

InsightBridge automatically organizes relevant information from ongoing interview conversations into an empathy map. It further allows researchers to specify elements to generate visual abstracts depicting the selected information, and then review these visuals with users to refine the visuals as needed. We evaluated the effectiveness of InsightBridge through a within-subject study (N=32) from both the researchers’ and users’ perspectives. Our findings indicate that InsightBridge can assist researchers in note-taking and organization, as well as in-time visual checking, thereby enhancing mutual understanding with users. Additionally, users’ discussions of visuals prompt them to recall overlooked details and scenarios, leading to more insightful ideas.","authors":[{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"The Hong Kong University of Science and Technology","dsl":""}],"personId":186867},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Shenzhen University","dsl":"School of Psychology"}],"personId":187507},{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"Hong Kong University of Science and Technology","dsl":""}],"personId":182874},{"affiliations":[{"country":"China","state":"","city":"Hong Kong ","institution":"The Hong Kong University of Science and Technology","dsl":""}],"personId":183217},{"affiliations":[{"country":"Hong Kong","state":"","city":"New Territories","institution":"The Hong Kong University of Science and Technology","dsl":"Department of Computer Science and Engineering"}],"personId":187566},{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"Hong Kong University of Science and Technology","dsl":""}],"personId":183431}]},{"id":188557,"typeId":13945,"title":"Closing the Loop between User Stories and GUI Prototypes: An LLM-Based Assistant for Cross-Functional Integration in Software Development","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713932"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=reLtGbdU_3I"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4214","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195116],"eventIds":[],"abstract":"Graphical user interfaces (GUIs) are at the heart of almost every software we encounter. GUIs are often created through a collaborative effort involving UX designers, product owners, and software developers, constantly facing changing requirements. Historically, problems in GUI development include a fragmented, poorly integrated tool landscape and high synchronization efforts between stakeholders. Recent approaches suggest using large language models (LLMs) to recognize requirements fulfillment in GUIs and automatically propose new GUI components. Based on ten interviews with practitioners, this paper proposes an LLM-based assistant as a Figma plug-in that bridges the gap between user stories and GUI prototyping. We evaluated the prototype with 40 users and 40 crowd-workers, showing that the effectiveness of GUI creation is improved by using LLMs to detect requirements' completion and generate new GUI components. We derive design rationales to support cross-functional integration in software development, ensuring that our plug-in integrates well into established processes.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Karlsruhe","institution":"Karlsruhe Institute of Technology (KIT)","dsl":""}],"personId":184891},{"affiliations":[{"country":"Germany","state":"","city":"Clausthal-Zellerfeld","institution":"Clausthal University of Technology","dsl":"Institute for Software and Systems Engineering"}],"personId":183814},{"affiliations":[{"country":"Germany","state":"","city":"Clausthal-Zellerfeld","institution":"Clausthal University of Technology","dsl":"Institute for Software and Systems Engineering"}],"personId":187014},{"affiliations":[{"country":"Germany","state":"","city":"Mannheim","institution":"University of Mannheim","dsl":"Data and Web Science Group"}],"personId":187177},{"affiliations":[{"country":"Germany","state":"","city":"Karlsruhe","institution":"Karlsruhe Institute of Technology (KIT)","dsl":"human-centered systems lab (h-lab)"}],"personId":187923}]},{"id":188558,"typeId":13945,"title":"User Motivations to Participate in Crowdsourcing and Contribute User-generated Content on Location-based Media: A Literature Review","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714184"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=reZoV84-lHk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4698","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195109],"eventIds":[],"abstract":"Location-based media applications such as Google Maps, Strava and Pokémon GO together have more than a billion monthly active users, and popular social media such as Snapchat and Instagram now also feature map-based content.

In this paper we ask: What are energy professionals' views of digital energy-saving interventions and their users? What are the challenges they face implementing these interventions? Based on a university campus case study with twelve semi-structured interviews and a focus group with energy and facilities' professionals, we illustrate how they strongly advocate digital efficiency as a pathway to sustainability; yet, this optimism is in apparent tension with key barriers they identify to realising 'their seamless visions', particularly the complexities of the human behaviour they are seeking to optimise. These findings underscore the seductiveness of techno-optimism and the need for more systemic change.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"Lancaster","institution":"Lancaster University","dsl":"School of Computing and Communications"}],"personId":188169},{"affiliations":[{"country":"United Kingdom","state":"Lancashire","city":"Lancaster","institution":"Lancaster University","dsl":"School of Computing and Communications"}],"personId":182739},{"affiliations":[{"country":"United Kingdom","state":"","city":"Lancaster","institution":"Lancaster University","dsl":"School of Computing and Communications"}],"personId":183095}]},{"id":188571,"typeId":13945,"title":"Crafting Champions: An Observation Study of Esports Coaching Processes","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713141"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=H0NptSo2Ifk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-5788","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195130],"eventIds":[],"abstract":"As esports grows into a multi-million dollar industry of professional players and competitions, so too grows the interest in and need for professional coaching.

We present ProcrastiMate, a text adventure game where players learn about procrastination's causes and experiment with coping strategies by guiding in-game characters in managing relatable scenarios. Our field study with 27 participants revealed that ProcrastiMate facilitated learning and self-reflection while maintaining psychological distance, motivating players to integrate newly acquired knowledge in daily life.

With large language models, adjusting explanation expressions has become much easier. However, how these expressions influence human decision-making remains largely unexplored. This study investigated the effect of explanation tone (e.g., formal or humorous) on decision-making, focusing on AI roles and user attributes. We conducted user experiments across three scenarios depending on AI roles (assistant, second-opinion provider, and expert) using datasets designed with varying tones. The results revealed that tone significantly influenced decision-making regardless of user attributes in the second-opinion scenario, whereas its impact varied by user attributes in the assistant and expert scenarios. In addition, older users were more influenced by tone, and highly extroverted users exhibited discrepancies between their perceptions and decisions. Furthermore, open-ended questionnaires highlighted that users expect tone adjustments to enhance their experience while emphasizing the importance of tone consistency and ethical considerations. Our findings provide crucial insights into the design of explanation expressions.","authors":[{"affiliations":[{"country":"Japan","state":"","city":"Aichi","institution":"Toyota Central R&D labs., Inc.","dsl":""}],"personId":184284},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"The University of Tokyo","dsl":""}],"personId":182721},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"The University of Tokyo","dsl":""}],"personId":187005}]},{"id":188583,"typeId":13945,"title":"Characterizing Photorealism and Artifacts in Diffusion Model-Generated Images","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713962"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=mP9OWBuOMqM"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-3375","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195103],"eventIds":[],"abstract":"Diffusion model-generated images can appear indistinguishable from authentic photographs, but these images often contain artifacts and implausibilities that reveal their AI-generated provenance.

This paper provides empirical evidence on the construction and organizational management of technical accuracy, demonstrating how technology companies' preoccupation with such values leads to harm. Drawing on nine months of multi-sited ethnographic fieldwork in China, we document how AI trainers' everyday work practices, challenges, and harms stem from clients' demands for high levels of technical accuracy. We introduce the concept of precision labor to unpack the labor dimension of constructing and performing accuracy in AI training. This concept highlights the hidden and excessive labor required to reconcile the ambiguity and uncertainty involved in this process. We argue that precision labor offers a new lens to illuminate three critical aspects of AI training: 1) the negative health and financial impacts of hidden and excessive labor on AI workers; 2) emerging harms, including workers' subordinate roles to machines and financial precarity; and 3) a conceptual contribution to contexts beyond AI training. This contribution re-centers arbitrariness in technical production, highlights the excessive demands of precision labor, and examines the legitimization of labor and harm. Our study also contributes to existing scholarship on the prevailing values and invisible labor in AI production, underscoring accuracy as performative rather than self-evident and unambiguous. A precision labor lens challenges the legitimacy and sustainability of relentlessly pursuing technical accuracy, raising new questions about its consequences and ethical implications. We conclude by proposing recommendations and alternative approaches to enhance worker agency and well-being.","authors":[{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":186908},{"affiliations":[{"country":"Germany","state":"","city":"Berlin","institution":"Technische Universität Berlin","dsl":"Weizenbaum Institute for the Networked Society"}],"personId":183268},{"affiliations":[{"country":"Germany","state":"","city":"Berlin","institution":"Technische Universität Berlin","dsl":"Weizenbaum Institute for the Networked Society"},{"country":"Germany","state":"","city":"Berlin","institution":"DAIR","dsl":"DAIR Institute"}],"personId":186751},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":186111},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":187503}]},{"id":188597,"typeId":13945,"title":"Breaking Barriers or Building Dependency?

In this paper, I share my co-evolving insights from research on tactile perception and vibrotactile material rendering, while reflecting on my PhD journey and speculating about the quest ahead.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Saarbrücken","institution":"Max Planck Institute for Informatics, Saarland Informatics Campus","dsl":"Sensorimotor Interaction"}],"personId":187734}]},{"id":188610,"typeId":13945,"title":"Backyard Practices: A Liminal Approach to Designing in More-than-Human Worlds","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713291"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=7izDj3PsQlE"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7946","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195100],"eventIds":[],"abstract":"As design researchers committed to more-than-human designing, we found we were increasingly moving our research activities outside of our institutional studios and labs into yards and balconies where we lived.

Our second study using less strict controls indicates that the role of crowd signals in decision-making is typically unrecognized by participants.

Instead, we propose that seeing & feeling information from the hands’ perspective could enhance flexibility & expressivity of sensory-substitution devices to support manual interactions with physical objects. To this end, we engineered a back-of-the-hand electrotactile-display that renders tactile images from a wrist-mounted camera, allowing the user’s hand to feel objects while reaching & hovering. We conducted a study with sighted/Blind-or-Low-Vision participants who used our eyes vs. hand tactile-perspectives to manipulate bottles and soldering-irons, etc. We found that while both tactile perspectives provided comparable performance, when offered the opportunity to choose, all participants found value in also using the hands’ perspective. Moreover, we observed behaviors when “seeing with the hands” that suggest a more ergonomic object-manipulation. We believe these insights extend the landscape of sensory-substitution devices.","authors":[{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":182918},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":182877},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":185022},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":183578}]},{"id":188639,"typeId":13942,"title":"Privacy for All: Empowering Vulnerable Groups with Diversity-Oriented Online Protection","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3707600"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=NxZQ82sGOGk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25l-3294","source":"PCS","trackId":13417,"tags":[],"keywords":[],"sessionIds":[191341,191333,191337,191334,191335,191336,191338,191340,195905,195906],"eventIds":[],"abstract":"Vertical data flows (e.g., those directed toward companies) are challenging to understand even for technically knowledgeable adults, exposing them to privacy risks.

To explore this, we conducted a technology probe study with 15 knowledge workers, integrating their real meeting data into two AI-assisted reflection probes: a passive and active design. Participants identified goal clarification as a foundational aspect of reflection. Goal clarity enabled people to assess when their meetings were off-track and reprioritize accordingly.

To aid to researchers in reporting and contextualizing their effect sizes within their research field as well as choosing effect sizes for power analysis, we conducted a meta-study of quantitative CHI papers. We extracted statistics from all quantitative CHI papers published between 2019-2023 (N=1692). Based on effect sizes and the papers' CCS categories, we present effect size distributions in 12 CHI research fields. Through an additional qualitative analysis of 67 quantitative CHI'23 publications, we identify five categories of approaches that researchers take when interpreting effect size: Comparing test-specific values, assigning size labels, using a statistical or methodological reference frame, comparing different observations and interpreting for the big picture.

We further refined our designs with 13 DHH users to determine the most preferred features. Based on this, we developed VRCaptions, a caption prototype for DHH users to better experience multiplayer conversations in VR. We lastly invited two mixed-hearing groups to participate in the VR room escape game with our VRCaptions to validate. The results demonstrate that VRCaptions can enhance the ability of DHH participants to access information and reduce the barrier to communication in VR.","authors":[{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Southern University of Science and Technology","dsl":""}],"personId":187212},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Southern University of Science and Technology","dsl":""}],"personId":186810},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Southern University of Science and Technology","dsl":""}],"personId":187226},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Southern University of Science and Technology","dsl":"School of Design"}],"personId":183098},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Southern University of Science and Technology","dsl":"School of Design"}],"personId":185778},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"SUSTech","dsl":""}],"personId":187706}]},{"id":188679,"typeId":13945,"title":"AiGet: Transforming Everyday Moments into Hidden Knowledge Discovery with AI Assistance on Smart Glasses","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713953"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=BLUNzt_pBd0"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-1271","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195080],"eventIds":[],"abstract":"Unlike the free exploration of childhood, the demands of daily life reduce our motivation to explore our surroundings, leading to missed opportunities for informal learning.

Through participatory design workshops with professional pilots, we identified key features and developed an adaptive AR interface that dynamically switches between task and safety views to prevent information overload. We evaluated our prototype by creating a realistic building inspection task and comparing three interfaces: a 2D tablet, a static AR, and our adaptive AR design. A user study with 15 participants showed that the AR interface improved access to safety information, while the adaptive AR interface reduced cognitive load and enhanced situational awareness without compromising task performance. We offer design insights for developing safety-first heads-up AR interfaces.","authors":[{"affiliations":[{"country":"Singapore","state":"","city":"Singapore","institution":"National University of Singapore","dsl":"Department of Computer Science"},{"country":"Singapore","state":"","city":"Singapore","institution":"IPAL","dsl":""}],"personId":188047},{"affiliations":[{"country":"France","state":"","city":"Toulouse","institution":"ENAC, Université de Toulouse","dsl":""}],"personId":186335},{"affiliations":[{"country":"Singapore","state":"","city":"Singapore","institution":"National University of Singapore","dsl":"Computer Science"}],"personId":185014},{"affiliations":[{"country":"Singapore","state":"","city":"Singapore","institution":"CNRS","dsl":"IPAL"},{"country":"France","state":"","city":"Toulouse","institution":"Univ of Toulouse 3","dsl":"IRIT"}],"personId":185492}]},{"id":188703,"typeId":13945,"title":"A Qualitative Study of Adoption Barriers and Challenges for Passwordless Authentication in German Public Administrations","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713252"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=YHibMJG62Xk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-2571","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195144],"eventIds":[],"abstract":"Public administrations provide critical services and manage sensitive data for a country's citizens.

Based on this, we developed the “COmpendium of RElatedness Technologies” (CORE), an open-access, searchable online database that provides researchers and practitioners with a reliable repository to inform future work. In addition, we present a systematic review of the corpus, revealing that despite its long tradition work on relatedness technologies remains characterized by limited theoretical grounding, lack of robust empirical evidence of effects, and insufficient attention to ethical considerations.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Ubiquitous Design | Experience & Interaction"}],"personId":187075},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Ubiquitous Design | Experience & Interaction"}],"personId":185305},{"affiliations":[{"country":"Germany","state":"","city":"Flensburg","institution":"Flensburg University of Applied Sciences","dsl":"Faculty of Information and Communication"}],"personId":183962},{"affiliations":[{"country":"Germany","state":"","city":"Flensburg","institution":"Flensburg University of Applied Sciences","dsl":"Faculty of Information and Communication"}],"personId":187286},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Ubiquitous Design / Experience & Interaction"}],"personId":184664},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Ubiquitous Design / Experience & Interaction"}],"personId":185481}]},{"id":188729,"typeId":13945,"title":"Raising Awareness of Location Information Vulnerabilities in Social Media Photos using LLMs","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714074"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=HVn1U2YnV4s"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-6706","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195028],"eventIds":[],"abstract":"Location privacy leaks can lead to unauthorised tracking, identity theft, and targeted attacks, compromising personal security and privacy.

These insights provide guidance for optimizing smartphone integration in hybrid interfaces and enhancing AR systems for reading applications.","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":"UVR Lab."}],"personId":187759},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"DAEJEON","institution":"KAIST KI-ITC ARRC","dsl":""}],"personId":186958},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":"UVR Lab"}],"personId":187337},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST ","dsl":"UVR Lab."},{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":"KI-ITC ARRC"}],"personId":187517}]},{"id":188751,"typeId":13945,"title":"What Do We Design for When We Design \"Smart Buildings\"? - A Scoping Review of Human Experience Design Research in Buildings","award":"BEST_PAPER","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713903"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=QDP_vRYh8gQ"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-2792","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195123],"eventIds":[],"abstract":"Built environments increasingly incorporate new forms of intelligence, creating opportunities for enhancing human interactive experiences with and within building spaces.

The design of HCI systems that involve social coordination will, we believe, need to take such effects into account.","authors":[{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"School of Computer Science"}],"personId":183850},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"Massachusetts Institute of Technology","dsl":"Media Lab"},{"country":"Japan","state":"","city":"Tokyo","institution":"Sony Computer Science Laboratories, Inc.","dsl":""}],"personId":187189},{"affiliations":[{"country":"United States","state":"Connecticut","city":"New Haven","institution":"Yale University","dsl":"Sociology"},{"country":"United States","state":"Connecticut","city":"New Haven","institution":"Yale Institute for Network Science","dsl":""}],"personId":187078},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"Sony Computer Science Laboratories, Inc.","dsl":""},{"country":"Japan","state":"","city":"Okinawa","institution":"Okinawa Institute of Science and Technology Graduate University","dsl":""}],"personId":187333}]},{"id":188756,"typeId":13945,"title":"RetroSketch: A Retrospective Method for Measuring Emotions and Presence in Virtual Reality","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713957"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=GRtFEqxlOCw"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4732","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195056],"eventIds":[],"abstract":"Virtual Reality (VR) designers and researchers often need to measure emotions and presence as they evolve over time. The experience sampling method (ESM) is a common way to achieve this, however, ESM disrupts the experience and lacks granularity. We propose RetroSketch, a new method for measuring subjective emotions and presence in VR, where users watch back their VR experience and retrospectively sketch a plot of their feelings. RetroSketch leaves the VR experience undisturbed and yields highly granular data, including information about salient events and qualitative descriptions of their feelings. We compared RetroSketch and ESM in a large study (n=140) using five different VR experiences over one-hour sessions. Our results show that RetroSketch and ESM measures are highly correlated with each other, as well as physiological measures indicative of emotion. The correlations are robust across different VR experiences and user demographics. They also highlight the impact of ESM on users' experience.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":184370},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":""}],"personId":183230},{"affiliations":[{"country":"United Kingdom","state":"Somerset","city":"Bath","institution":"University of Bath","dsl":"Human Computer Interaction Lab, Department of Computer Science"}],"personId":184850},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Human Computer Interaction (HCI) Department"}],"personId":185874},{"affiliations":[{"country":"United Kingdom","state":"Somerset","city":"Bath","institution":"University of Bath ","dsl":"HCI Lab"}],"personId":186205},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":184103},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":184219},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":185863},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":185439},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":""}],"personId":182869},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":186260},{"affiliations":[{"country":"United Kingdom","state":"","city":"Bath","institution":"University of Bath","dsl":"Computer Science"}],"personId":182965}]},{"id":188757,"typeId":13948,"title":"How do design stories work?

This framework leverages a structured idea representation, an analogy-based reasoning mechanism and interactive visualization techniques. It guides both designers and AI to systematically explore design spaces. We also develop a prototype system, IdeationWeb, which integrates an intuitive, mind map-like visual interface and interactive methods to support co-ideation. Our user study validates the framework’s feasibility, demonstrating enhanced collaboration and creativity between humans and AI.

To evaluate ChromaConnect's ability to support neurodiverse social play in different contexts, we observed children using it in both structured and unstructured play settings. Our findings show that ChromaConnect enabled children to create a common language of play, made divergent play modes more visible, and facilitated explicit expression of social play initiation.

Technology has impacted our ability to rest through its colonisation of our attention, sleep, and recovery. Human-computer interaction researchers and designers have expressed the desire to contribute to human flourishing. However, design to support restful states remains largely tethered to human-centric paradigms. This paper identifies an oversight in human-computer interaction research and recognises rest as a more-than-human phenomenon that emerges through a dynamic interplay of multiple species, technologies, and ecosystems. We discuss this topic through the Daoist concepts of `Yin-Yang' and `Wu-Wei' as theoretical foundations for frameworks that reimagine the future of rest. We critically evaluate anthropocentric approaches to rest by reflecting on how embodied knowledge and practice can serve to bridge relational theories with practice. We propose a manifesto for `More-than-Human Yin-teraction' that outlines design principles foregrounding rest as a dynamic and evolving ecology where regenerative states emerge through the entangled relations between human, nonhuman and natural systems.","authors":[{"affiliations":[{"country":"Australia","state":"NSW","city":"Sydney","institution":"University of Sydney","dsl":"Design Lab, School of Architecture, Design and Planning"}],"personId":187129},{"affiliations":[{"country":"Australia","state":"","city":"Melbourne","institution":"The University of Melbourne","dsl":""}],"personId":185864},{"affiliations":[{"country":"Singapore","state":"","city":"Singapore","institution":"National University of Singapore","dsl":"Division of Industrial Design"}],"personId":185769}]},{"id":188795,"typeId":13945,"title":"Understanding the Effects of AI-based Credibility Indicators When People Are Influenced By Both Peers and Experts","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713871"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=N-UDcLA0gPg"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4957","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195106],"eventIds":[],"abstract":"In an era marked by rampant online misinformation, artificial intelligence (AI) technologies have emerged as tools to combat this issue.

Notably, these effects remain consistent regardless of whether experts' expertise is verified, with particularly significant impacts when AI predictions disagree with experts. However, the competence of AI moderates the effects, as incorrect predictions can mislead people. Furthermore, exploratory analyses suggest that under our experimental settings, the impact of the AI-based credibility indicator is larger than that of the expert's. Additionally, AI's influence on people is partially mediated through peer influence, although people automatically discount the opinions of their laypeople peers when seeing an agreement between AI and peers' opinions.

The light touch effect refers to improved balance when a person lightly touches a surface, such as a wall or handrail, with a force of 1 N or less. We replicate this effect utilizing focused ultrasound to create a tactile point in mid-air. When users interact with this invisible tactile point, they experience the light touch effect, which subsequently improves their balance. We conducted a pilot study with 29 participants and a user study with 25 older adults, evaluating the balance improvement by measuring the center of pressure trajectory. The results confirmed that standing balance improved significantly when using the ILT.","authors":[{"affiliations":[{"country":"Japan","state":"Kanagawa","city":"Yokosuka","institution":"NTT Corporation","dsl":"NTT Human Informatics Laboratories"}],"personId":185300},{"affiliations":[{"country":"Japan","state":"","city":"Yokosuka, Kanagawa","institution":"NTT Corporation","dsl":"NTT Human Informatics Laboratories"}],"personId":183389},{"affiliations":[{"country":"Japan","state":"","city":"Yokosuka, Kanagawa","institution":"NTT Corporation","dsl":"NTT Human Informatics Laboratories"}],"personId":185026}]},{"id":188821,"typeId":13945,"title":"TutorUp: What If Your Students Were Simulated?

Using surveys and interviews, we investigated USA remote and hybrid workers' experiences with three types of cyber incivility (hostility, gossip, and exclusion), and follow-up support. We found cyber incivility experiences are more common among workers who spend more time at the office, and among women than men.

Most guidance for such tasks relies on decomposing available DOF into subspaces that can be more easily mapped to simple 1D or 2D visualizations. Unfortunately, different factorizations of the same motion often map to very different visual feedback, and finding the factorization that best matches a user’s intuition can be difficult. We propose an interactive approach that infers rotational degrees of freedom from short user demonstrations. Users select one or two DOFs at a time by demonstrating a small range of motion, which we use to learn a rotational frame that best aligns with user control of the object.

To advance plan-focused pedagogies in application-focused domains, we created an LLM-powered pipeline that automates the effortful parts of educators' plan identification process by providing use-case-driven program examples and candidate plans. In design workshops (N=7 educators), we identified design goals to maximize instructors' efficiency in plan identification by optimizing interaction with this LLM-generated content. Our resulting tool, PLAID, enables instructors to access a corpus of relevant programs to inspire plan identification, compare code snippets to assist plan refinement, and facilitates them in structuring code snippets into plans. We evaluated PLAID in a within-subjects user study (N=12 educators) and found that PLAID led to lower cognitive demand and increased productivity compared to the state-of-the-art. Educators found PLAID beneficial for generating instructional material.

This new framework for evaluating urban landscapes aims to reduce uncertainty in robot deployment while respecting established mobility patterns and urban planning principles, contributing to the discourse on harmonious human-robot environments.\r\n","authors":[{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Cornell Tech","dsl":"Computer Science"}],"personId":183456},{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Cornell University","dsl":"Information Science"}],"personId":186663},{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Cornell Tech","dsl":"Computer Science"}],"personId":185810},{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Cornell Tech","dsl":"Information Science"}],"personId":185947}]},{"id":188873,"typeId":13948,"title":"Maternal Machines: Imagining Experiences in Perinatal Care","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3706744"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25q-1305","source":"PCS","trackId":13413,"tags":[],"keywords":[],"sessionIds":[190334],"eventIds":[],"abstract":"Perinatal care is a term that broadly refers to the period of time from pregnancy up to a year after giving birth. Imaginaries, fictional scenarios, patents and actual designs to support affected stakeholders during this period reflect how this topic has for a long time fed into society’s dreams, fears and desires about care. Smart monitors of infants’ sleep, respiration, heart rate or temperature, cots with facial recognition, swing chairs that are ‘Alexa compatible’, chatbots for postpartum depression, ‘maternal’ Alexas or nanny robots are examples of the potentials that this topic offers for imagining scenarios for care and wellbeing. Often rich with insights about societal dreams, fears and desires about what we would like technologies to do for us, imagined scenarios can also indicate ways in which we regard those already engaged in roles of care, echoing cultural and gendered tropes. As AI and related technologies increasingly become entangled in situations of care, the imagined possibilities in contexts of such complex, sensitive and emotionally charged spaces are worth examining, whilst interrogating how HCI technologies in perinatal care could expand beyond quantifiable data and tap into sensorial, non-numerical forms of knowledge.\r\nIn this workshop, we will look at ideated scenarios with technologies related to maternal and infant care in contemporary, historical and cultural contexts including those from Japan, and we will create our own imagined scenarios of care. Through a mixture of activities that include presentations, drawing, hands-on interactions and group conversations we will discuss opportunities and implications in the design of technologies for maternal/parental and infant care around the perinatal period. Our imagined scenarios will explore in particular two interrelated themes in the research: non-numerical forms of knowledge and touch.\r\n","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"University of the Arts London","dsl":""}],"personId":183917},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"University of the Arts London","dsl":""}],"personId":182693},{"affiliations":[{"country":"Sweden","state":"","city":"Stockholm","institution":"KTH Royal Institute of Technology","dsl":""}],"personId":183307},{"affiliations":[{"country":"Sweden","state":"","city":"Stockholm","institution":"KTH Royal Institute of Technology","dsl":""}],"personId":188108},{"affiliations":[{"country":"Sweden","state":"","city":"Stockholm","institution":"KTH Royal Institute of Technology","dsl":"Media Technology and Interaction Design"}],"personId":187767},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"Imperial College London","dsl":"Dyson School of Design Engineering"}],"personId":183898},{"affiliations":[{"country":"Italy","state":"","city":"Turin","institution":"Politecnico di Torino ","dsl":"Department of Architecture and Design "}],"personId":183956}]},{"id":188874,"typeId":13945,"title":"\"Who is running it?\" Towards Equitable AI Deployment in Home Care Work","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713850"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=UjGXW5L_S7E"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8272","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195008],"eventIds":[],"abstract":"We present a qualitative study that investigates the implications of current and near-future AI deployment for home care workers (HCWs), an overlooked group of frontline healthcare workers.

The robots were developed by an on-site technical team, and our research team of social scientists was consulted to explore workers’ perspectives. We compared four versions of the robot (without any features, with a name, with eyes and with a display) using mixed methods, including ethnography, interviews and surveys. Collecting data via periodic surveys proved challenging since the warehouse employees were busy during peak seasons (high workload) and due to technical issues with the robots. These factors necessitated a more flexible approach. Nonetheless, our study provided valuable insights that were considered during the robot implementation. In this case study, we summarise the results, lessons learned, and suggestions that could help navigate future field studies in industrial environments.","authors":[{"affiliations":[{"country":"Belgium","state":"","city":"Brussels","institution":"Vrije Universiteit Brussel","dsl":"imec - SMIT"}],"personId":187183},{"affiliations":[{"country":"Belgium","state":"","city":"Brussel","institution":"Vrije Universiteit Brussel","dsl":"imec - SMIT"},{"country":"Belgium","state":"","city":"Brussels","institution":"FARI - AI for the Common Good Institute","dsl":""}],"personId":187181},{"affiliations":[{"country":"Belgium","state":"","city":"Brussels","institution":"imec - SMIT, Vrije Universiteit Brussel","dsl":""}],"personId":185226},{"affiliations":[{"country":"Belgium","state":"","city":"Brussel","institution":"Vrije Universiteit Brussel","dsl":"imec - SMIT"}],"personId":186693}]},{"id":188886,"typeId":13945,"title":"Translating HCI Research to Broader Audiences: Motivation, Inspiration, and Critical Factors on Alternative Research Outcomes","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713884"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=eljtknmHJ5g"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9377","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195055],"eventIds":[],"abstract":"Alternative Research Outcomes (AROs) go beyond traditional academic publications, taking diverse forms such as documentaries, DIY tutorials, or exhibitions.

The work contributes 1) new considerations of the generative and designerly potential storytelling and fiction in more-than-human research 2) queer embodied approaches to MTH work in HCI 3) and non-binary ethics for MTH design that imagine pluriversal bodily consent and paths to entangled healing.

As creative work shifts online, interactions between artists and routines around how these artists get inspired to do creative work are mediated by and through the logics of the online platforms where they take place. In an interview study of 22 artists, this paper explores the interplay between the development of artists' creative identities and the, at times, contradictory practices they have around getting inspired. We find platforms which support the disciplined practice of creative work while supporting spontaneous moments of inspiration, play an increasing role in passive approaches to searching for inspiration, and foster numerous small community spaces for artists to negotiate their creative identities. We discuss how platforms can better support and embed mechanisms for inspiration into their infrastructures into their design and platform policy.","authors":[{"affiliations":[{"country":"United States","state":"Virginia","city":"Charlottesville","institution":"University of Virginia","dsl":"School of Data Science"}],"personId":183531},{"affiliations":[{"country":"United States","state":"Colorado","city":"Boulder","institution":"University of Colorado Boulder","dsl":"Department of Information Science"}],"personId":183196}]},{"id":188899,"typeId":13945,"title":"Speculating Deaf Tech: Reimagining Technologies Centering Deaf People","award":"BEST_PAPER","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713238"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=LjpJRugxRT8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4927","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195003],"eventIds":[],"abstract":"This deaf-led work critically explores Deaf Tech, challenging conventional understandings of technologies 'for' deaf people as merely assistive and accessible, since these understandings are predominantly embedded in medical and audist ideologies.

Responding to the absence of overarching guidance for moving beyond traditional aesthetics, this paper systematically reviews more-than-human aesthetic perspectives within and beyond HCI and design. We first examine contemporary critical aesthetic discourse across disciplines such as art, geography, and human-animal interaction, identifying three key orientations that move away from human-centric aesthetics---phenomenologically, ontologically, and conceptually. We then review artefact-oriented publications in HCI and design venues to offer concrete examples of how these perspectives can be navigated, interpreted, combined, and applied in practice.

To address this, we introduce Brickify, a visual-centric interaction paradigm — expressing design intent through direct manipulation on design tokens. Brickify extracts visual elements (e.g., subject, style, and color) from reference images and converts them into interactive and reusable design tokens that can be directly manipulated (e.g., resize, group, link, etc.) to form the visual lexicon. The lexicon reflects users’ intent for both what visual elements are desired and how to construct them into a whole. We developed Brickify to demonstrate how AI models can interpret and execute the visual lexicon through an end-to-end pipeline. In a user study, experienced designers found Brickify more efficient and intuitive than text-based prompts, allowing them to describe visual details, explore alternatives, and refine complex designs with greater ease and control.","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":""}],"personId":184345},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"Harvard University","dsl":"Graduate School of Design"}],"personId":185202},{"affiliations":[{"country":"United States","state":"California","city":"San Jose","institution":"Adobe Research","dsl":""}],"personId":185172},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"School of Computer Science"}],"personId":185516}]},{"id":188913,"typeId":13945,"title":"Pagebreaks: Multi-Cell Scopes in Computational Notebooks","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713620"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=pr3sKCt9JVs"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9588","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195001],"eventIds":[],"abstract":"Global variables lie at the root of many programmer complaints about computational notebooks.While programmers in other environments often address these barriers with function scopes, notebook programmers use functions less often.

For example, because partial functions are not parseable, they cannot be run in isolation, so programmers cannot split function bodies across cells to iteratively tweak and rerun the last few lines. To explore how to offer non-global scopes without hampering exploratory notebook interactions, we built Pagebreaks, a small language construct for adding scopes around multiple Jupyter Notebook cells. In an in-situ study, we explored how programmers used Pagebreaks to manage variables with non-global scopes but also to visually and conceptually organize programs in a way akin to functions.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"University of California, Berkeley","dsl":"Electrical Engineering and Computer Science"}],"personId":185418},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"University of California, Berkeley","dsl":"Electrical Engineering and Computer Sciences"}],"personId":184097}]},{"id":188914,"typeId":13945,"title":"Disentangling the Power Dynamics in Participatory Data Physicalisation","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713703"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=w_XoJV5VrA8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7162","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195047],"eventIds":[],"abstract":"Participatory data physicalisation (PDP) is recognised for its potential to support data-driven decisions among stakeholders who collaboratively construct physical elements into commonly insightful visualisations. \r\nLike all participatory processes, PDP is however influenced by underlying power dynamics that might lead to issues regarding extractive participation, marginalisation, or exclusion, among others.\r\nWe first identified the decisions behind these power dynamics by developing an ontology that synthesises critical theoretical insights from both visualisation and participatory design research, which were then \r\nsystematically applied unto a representative corpus of 23 PDP artefacts. \r\nBy revealing how shared decisions are guided by different agendas, this paper presents three contributions: \r\n1) a cross-disciplinary ontology that facilitates the systematic analysis of existing and novel PDP artefacts and processes; which leads to\r\n2) six PDP agendas that reflect the key power dynamics in current PDP practice, revealing the diversity of orientations towards stakeholder participation in PDP practice; and\r\n3) a set of critical considerations that should guide how power dynamics can be balanced, such as by reflecting on how issues are represented, data is contextualised, participants express their meanings, and how participants can dissent with flexible artefact construction.\r\nConsequently, this study advances a feminist research agenda by guiding researchers and practitioners in openly reflecting on and sharing responsibilities in data physicalisation and participatory data visualisation.","authors":[{"affiliations":[{"country":"Belgium","state":"","city":"Leuven","institution":"KU Leuven","dsl":""}],"personId":182894},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"King's College London","dsl":""}],"personId":185679},{"affiliations":[{"country":"Belgium","state":"","city":"Leuven","institution":"Division of Geography and Tourism","dsl":"KU Leuven"}],"personId":183759},{"affiliations":[{"country":"Belgium","state":"","city":"Leuven","institution":"KU Leuven","dsl":"Research[x]Design - Department of Architecture"}],"personId":182765}]},{"id":188915,"typeId":13945,"title":"FingerGlass: Enhancing Smart Glasses Interaction via Fingerprint Sensing","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713929"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=8OytALyZ5uk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9343","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195076],"eventIds":[],"abstract":"Smart glasses hold immense potential, but existing input methods often hinder their seamless integration into everyday life.

The results suggested that to facilitate queer joy online, platforms should allow flexible self expression and community engagement, while allowing for granular control over privacy and the audience such content is shown to.","authors":[{"affiliations":[{"country":"Ireland","state":"","city":"Dublin","institution":"University College Dublin","dsl":"School of Information and Communication Studies"}],"personId":184712},{"affiliations":[{"country":"United Kingdom","state":"","city":"Manchester","institution":"The University of Manchester","dsl":"Department of Computer Science"}],"personId":187433},{"affiliations":[{"country":"United Kingdom","state":"","city":"Newcastle","institution":"Northumbria University","dsl":"Centre for Digital Citizens"}],"personId":185747},{"affiliations":[{"country":"United Kingdom","state":"","city":"Newcastle","institution":"Northumbria University","dsl":""}],"personId":183027},{"affiliations":[{"country":"United Kingdom","state":"","city":"Leeds","institution":"Leeds Beckett University","dsl":""}],"personId":183500},{"affiliations":[{"country":"United Kingdom","state":"","city":"Southampton","institution":"University of Southampton","dsl":""}],"personId":185377},{"affiliations":[{"country":"United Kingdom","state":"","city":"York","institution":"Independent Researcher","dsl":""}],"personId":183958},{"affiliations":[{"country":"United Kingdom","state":"","city":"Leeds","institution":"Leeds Arts University","dsl":""}],"personId":185576}]},{"id":188926,"typeId":13945,"title":"Exploring K-12 Physical Education Teachers’ Perspectives on Opportunities and Challenges of AI Integration through Ideation Workshops","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713646"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=n8Tw8YFz5sA"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7178","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195140],"eventIds":[],"abstract":"While AI's potential in education and professional sports is widely recognized, its application in K-12 physical education (PE) remains underexplored with significant opportunities for innovation.

As interface design significantly impacts survey results and accuracy, our design scaffolds survey takers' decision-making while managing the cognitive load imposed by QS. In a 2x2 between-subject in-lab study on public resource allotment, we compared our interface with a traditional text interface across a QS with 6 (short) and 24 (long) options.

With the global rise in gig workers, there is an increasing urgency for HCI and design research to focus on the impact of designing automation technologies on labor dynamics. This study introduces speculative job design research to probe alternative opportunities for gig workers in an automated future, engaging 20 workers in the process. Guided by Feminist HCI, we performed reflexive thematic analysis to uncover gig workers' views on automation technology, human labor, speculative jobs, and their concerns about the future of work. We highlighted how workers see labor exploitation as a competitive asset over machines, urging that future platform designs must not perpetuate this. Notably, through speculative job design and conversation with workers, we proposed labor design, suggesting labor as a designable material to help address unfair labor dynamics in technology design. Our research offers potential insights and directions for addressing labor tensions in the evolving sociotechnical landscape.","authors":[{"affiliations":[{"country":"Portugal","state":"","city":"Lisbon","institution":"Instituto Superior Técnico, University of Lisbon","dsl":"ITI / LARSyS"}],"personId":182944},{"affiliations":[{"country":"China","state":"","city":"Tianjin","institution":"Tianjin University","dsl":""}],"personId":185884},{"affiliations":[{"country":"Portugal","state":"","city":"Lisbon","institution":"IST University of Lisbon","dsl":"ITI/LARSyS"}],"personId":183484},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute"}],"personId":184169},{"affiliations":[{"country":"Portugal","state":"","city":"Lisbon","institution":"Instituto Superior Técnico - U.

Based on participants' responses, we identified the key stages in which they commonly integrated AI, including story structure and plot development, screenplay text, goal and idea generation, and dialogue. Then, we examined how different attitudes toward AI integration influence screenwriters' practices across various workflow stages and their broader impact on the industry.

We present a fully-reproducible study in which we demonstrate that scatterplot manipulations that are able to correct for the correlation underestimation bias can also induce stronger levels of belief change compared to conventional scatterplots presenting identical data. Consequently, we show that novel visualisation techniques can be used to drive belief change, and suggest future directions for extending this work with regards to altering attitudes and behaviours.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"Manchester","institution":"University of Manchester","dsl":"Department of Computer Science, Faculty of Science and Engineering"}],"personId":183351},{"affiliations":[{"country":"United Kingdom","state":"","city":"Manchester","institution":"University of Manchester","dsl":"Department of Computer Science, Faculty of Science and Engineering"}],"personId":186560},{"affiliations":[{"country":"United Kingdom","state":"","city":"Manchester","institution":"University of Manchester","dsl":"Department of Computer Science, Faculty of Science and Engineering"}],"personId":184334},{"affiliations":[{"country":"United Kingdom","state":"","city":"Manchester","institution":"University of Manchester","dsl":"Division of Psychology Communication and Human Neuroscience, Schoolof Health Sciences, Faculty of Biology, Medicine, and Health"}],"personId":185623},{"affiliations":[{"country":"United Kingdom","state":"","city":"Manchester","institution":"University of Manchester","dsl":"Division of Psychology Communication and Human Neuroscience, Schoolof Health Sciences, Faculty of Biology, Medicine, and Health"}],"personId":187546}]},{"id":188962,"typeId":13945,"title":"Understanding Children's Avatar Making in Social Online Games","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713262"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8487","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195013],"eventIds":[],"abstract":"Social online games like Minecraft and Roblox have become increasingly integral to children's daily lives. Our study explores how children aged 8 to 13 create and customize avatars in these virtual environments. Through semi-structured interviews and gameplay observations with 48 participants, we investigate the motivations behind children's avatar-making. Our findings show that children's avatar creation is motivated by self-representation, experimenting with alter ego identities, fulfilling social needs, and improving in-game performance. In addition, designed monetization strategies play a role in shaping children's avatars. We identify the ''wardrobe effect,'' where children create multiple avatars but typically use only one favorite consistently. We discuss the impact of cultural consumerism and how social games can support children's identity exploration while balancing self-expression and social conformity. This work contributes to understanding how avatar shapes children's identity growth in social online games.","authors":[{"affiliations":[{"country":"United States","state":"Washington","city":"Seattle","institution":"University of Washington","dsl":"Information School"}],"personId":183326},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Boston","institution":"Boston Children's Hospital","dsl":"Digital Wellness Lab"}],"personId":185570},{"affiliations":[{"country":"United States","state":"Washington","city":"Seattle","institution":"University of Washington","dsl":"Paul G.

Finally, a machine can be conceptually significant; the use of the machine can change what a piece means and how it is perceived. We found that clay 3D printers: 1) are labor intensive to operate and do not improve efficiency; 2) can present new and compelling creative opportunities; 3) are conceptually fraught.

Using a dataset of more than 54,000 DMCA reports and over 85 million infringing URLs spanning over a decade, this paper evaluates the efficacy of the DMCA for NCIM takedown. Results show that for non-commercial requests, while more than half of URLs are deindexed from Google Search within 48 hours, the actual removal of content from website hosts is much slower. The median infringing URL takes more than 45 days to be removed from website hosts, and only 5.39% URLs are removed within the first 48 hours. Additionally, the most frequently reported domains for non-commercial NCIM are smaller websites, not large platforms. We stress the need for new laws that ensure a shorter time to takedown that are enforceable across big and small platforms alike.","authors":[{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":184301},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":188082},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":182951},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":185471},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":182729},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":186644}]},{"id":188965,"typeId":13945,"title":"Signaling Human Intentions to Service Robots: Understanding the Use of Social Cues during In-Person Conversations","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714235"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=iUH8Oag2Dso"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7393","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195075],"eventIds":[],"abstract":"As social service robots become commonplace, it is essential for them to effectively interpret human signals, such as verbal, gesture, and eye gaze, when people need to focus on their primary tasks to minimize interruptions and distractions.

While workers generally value the ability to schedule flexibly, this flexibility is constrained by structural factors such as piece-rate remuneration, demand fluctuations, surge pricing, and income dependency. The constraints result in markedly different experiences across the different instantiations of the same, standardised delivery platform: workers in Denmark benefit from the system, in Finland workers face seasonal precarity, and in Malta workers endure exploitative cycles of long hours and low pay. The findings demonstrate how the same platform's standardised design can produce divergent outcomes in local contexts. The paper highlights the need for platform designers and regulators to balance the benefits of flexible scheduling with its trade-offs, ensuring that flexibility supports worker well-being as the flexible platforms manifest locally.

In the user study, we evaluate their effectiveness in reducing task completion time, errors, and effort. The results indicate the strengths and weaknesses of each technique, with SemiSwipe and SemiDwell as the most preferred methods by participants.

Furthermore, children's desire for privacy controls remains understudied. To fill the gap, we conducted two five-day co-design workshops with 11 children (ages 6-11).

To bridge this gap, we interviewed 13 regular social VR meditators to explore their practices, perceived benefits, and challenges. We found that meditators utilized platform features to engage in community-driven group practices, manage session flow, employ avatars and body tracking for kinetic practices, and experiment with novel forms of meditation. Participants reported benefits and challenges related to the individual and social aspects of their meditation experiences. Based on these findings, we discuss the implications of using social VR for meditation, including how avatars and virtual others positively affect the practice, as well as emerging tensions and opportunities.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"Irvine","institution":"University of California Irvine","dsl":"Informatics"}],"personId":187018},{"affiliations":[{"country":"United States","state":"New York","city":"Buffalo","institution":"University at Buffalo,SUNY","dsl":"Information Science"}],"personId":183585},{"affiliations":[{"country":"United States","state":"California","city":"Irvine","institution":"University of California, Irvine","dsl":"Informatics"}],"personId":186650},{"affiliations":[{"country":"United States","state":"California","city":"Irvine","institution":"University of California, Irvine","dsl":"Informatics"}],"personId":187980},{"affiliations":[{"country":"United States","state":"California","city":"irvine","institution":"university of california, irvine","dsl":"informatics, connected learning lab"}],"personId":184016}]},{"id":189012,"typeId":13945,"title":"\"Did you sleep well?\": A Multimodal Sleep Diary for Sustained Self-Reporting by Children","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713425"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=IqpC0Wv7UqY"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-1712","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195156],"eventIds":[],"abstract":"Sleep diaries are essential self-reporting tools for understanding children's sleep patterns, but maintaining sustained engagement and high-quality self-reporting remains challenging. While voice input has been explored in child-computer interaction research as a method to improve engagement, limited evidence exists regarding its effectiveness in supporting sustained self-reporting over time. To address this gap, we conducted a five-day field study with 20 children aged seven to twelve, using a multimodal sleep diary that integrated both voice and text input modalities. Our findings reveal that voice input significantly supports younger children in maintaining engagement over five days, though their response quality remains lower than that of older children. Two distinct response quality patterns over time also emphasize the importance of accounting for individual differences in task performance. Furthermore, input modality preferences varied by age: older children consistently favored text input, while younger children generally preferred voice input over time. These results highlight the potential of incorporating voice input into text-based sleep diaries to better accommodate the diverse needs of children, enhancing both sustained engagement and response quality. Future studies with longer observation periods are needed to validate and extend these findings.","authors":[{"affiliations":[{"country":"Netherlands","state":"","city":"Eindhoven","institution":"Eindhoven University of Technology","dsl":"Department of Industrial Design"}],"personId":186429},{"affiliations":[{"country":"Netherlands","state":"","city":"Eindhoven","institution":"Eindhoven University of Technology","dsl":"Department of Industrial Design"}],"personId":187650},{"affiliations":[{"country":"Netherlands","state":"","city":"Eindhoven","institution":"Eindhoven University of Technology","dsl":"Department of Industrial Design"}],"personId":187025},{"affiliations":[{"country":"Netherlands","state":"","city":"Eindhoven","institution":"Eindhoven University of Technology","dsl":"Department of Industrial Design"}],"personId":182996},{"affiliations":[{"country":"Netherlands","state":"","city":"Eindhoven","institution":"Eindhoven University of Technology","dsl":"Department of Industrial Design"}],"personId":183631}]},{"id":189013,"typeId":13942,"title":"Design and Fabrication of Hybrid Functional Identities for Mechanical Elements","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3707635"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=JnpqSmKi0Hs"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25l-8609","source":"PCS","trackId":13417,"tags":[],"keywords":[],"sessionIds":[191341,191333,191337,191334,191335,191336,191338,191340,195905,195906],"eventIds":[],"abstract":"My PhD research explores the simultaneous integration of me-\r\nchanical and electrical functionalities in mechanical components\r\nsuch as gears, linkages, and springs, which I define as “hybrid func-\r\ntional identities.” The focus is on transforming these components\r\ninto non-intrusive sensors and active elements that maintain struc-\r\ntural integrity while providing electrical capabilities like sensing,\r\nenergy harvesting, and communication.

For effective assistance in physical tasks, enabling SRLs to hand over objects to humans is crucial. Yet, designing heuristic-based policies for robots is time-consuming, difficult to generalize across tasks, and results in less human-like motion. When trained with proper datasets, generative models are powerful alternatives for creating naturalistic handover motions. We introduce 3HANDS, a novel dataset of object handover interactions between a participant performing a daily activity and another participant enacting a hip-mounted SRL in a naturalistic manner. 3HANDS captures the unique characteristics of SRL interactions: operating in intimate personal space with asymmetric object origins, implicit motion synchronization, and the user’s engagement in a primary task during the handover. To demonstrate the effectiveness of our dataset, we present three models: one that generates naturalistic handover trajectories, another that determines the appropriate handover endpoints, and a third that predicts the moment to initiate a handover. In a user study (N=10), we compare the handover interaction performed with our method compared to a baseline. The findings show that our method was perceived as significantly more natural, less physically demanding, and more comfortable.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Saarbrücken","institution":"Saarland University, Saarland Informatics Campus","dsl":""}],"personId":183433},{"affiliations":[{"country":"Switzerland","state":"","city":"Zürich","institution":"ETH Zürich","dsl":""}],"personId":184725},{"affiliations":[{"country":"Germany","state":"Saarland","city":"Saarbrücken","institution":"Saarland Informatics Campus","dsl":"Saarland University"}],"personId":185756},{"affiliations":[{"country":"Germany","state":"","city":"Saarbrucken","institution":"Max-Planck Institute for Informatics","dsl":"Visual Computing and Artificial Intelligence"}],"personId":185448},{"affiliations":[{"country":"Germany","state":"","city":"Saarbrücken","institution":"Saarland Informatics Campus","dsl":"Saarland University"}],"personId":187245},{"affiliations":[{"country":"Germany","state":"","city":"Saarbrucken","institution":"Max Planck Institute for Informatics","dsl":"GVV Group"}],"personId":183395},{"affiliations":[{"country":"Germany","state":"","city":"Saarbrücken","institution":"Saarland Informatics Campus","dsl":"Saarland University"}],"personId":183166},{"affiliations":[{"country":"Germany","state":"","city":"Saarbrücken","institution":"Saarland University, Saarland Informatics Campus","dsl":""}],"personId":185688}]},{"id":189026,"typeId":13945,"title":"Visual Augmentations for Ultrasound Assessment Training of Medical Students","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714004"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=q8DHHaz-lIo"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-6377","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195074],"eventIds":[],"abstract":"Ultrasound assessments are key in assessing traumatic injuries to the human body during urgent medical emergencies.

With this, we aim to inspire the design of future immersive offices.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Interactive Media Lab Dresden"}],"personId":183294},{"affiliations":[{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Interactive Media Lab Dresden"},{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Centre for Tactile Internet with Human-in-the-Loop (CeTI)"}],"personId":185129},{"affiliations":[{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Interactive Media Lab Dresden"}],"personId":185069},{"affiliations":[{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Interactive Media Lab Dresden"},{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Centre for Tactile Internet with Human-in-the-Loop (CeTI)"}],"personId":185451}]},{"id":189038,"typeId":13945,"title":"\"Impressively Scary:\" Exploring User Perceptions and Reactions to Unraveling Machine Learning Models in Social Media Applications","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713256"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=DAt5LFq055c"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-6379","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195106],"eventIds":[],"abstract":"Machine learning models deployed locally on social media applications are used for features, such as face filters which read faces in-real time, and they expose sensitive attributes to the apps.

We conducted twenty interviews where participants explained their rationale for their judgments about who should receive a kidney. We observe participants: (a) value patients' morally-relevant attributes to different degrees; (b) use diverse decision-making processes, citing heuristics to reduce decision complexity; (c) can change their opinions; (d) sometimes lack confidence in their decisions (e.g., due to incomplete information); and (e) express enthusiasm and concern regarding AI assisting humans in kidney allocation decisions. Based on these findings, we discuss challenges of computationally modeling moral judgments as a stand-in for human input, highlight drawbacks of current approaches, and suggest future directions to address these issues.\r\n","authors":[{"affiliations":[{"country":"United States","state":"North Carolina","city":"Durham","institution":"Duke University","dsl":""}],"personId":187606},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":""}],"personId":185401},{"affiliations":[{"country":"United States","state":"North Carolina","city":"Durham","institution":"Duke University","dsl":""}],"personId":183781},{"affiliations":[{"country":"United States","state":"Connecticut","city":"New Haven","institution":"Yale University","dsl":""}],"personId":185640},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":""}],"personId":186228},{"affiliations":[{"country":"United States","state":"North Carolina","city":"Durham","institution":"Duke University","dsl":""}],"personId":184547}]},{"id":189052,"typeId":13950,"title":"Field Trials of Autonomous Navigation Robot for Visually Impaired People","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3706663"},"Presentation Video":{"hideAfterConference":false,"hideBeforeConference":true,"hideFromPublicJson":false,"isAvailableForRegisteredMembersOnly":false,"title":"Field Trials of Autonomous Navigation Robot for Visually Impaired People","type":"video","url":"https://www.youtube.com/watch?v=WLAMvOQlgts"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25j-5093","source":"PCS","trackId":13415,"tags":[],"keywords":[],"sessionIds":[189996],"eventIds":[],"abstract":"Despite the advances made in assistive technologies for people with visual impairments, challenges remain in unfamiliar public spaces such as shopping malls, museums, and transit hubs.

It does suffer however from various drawbacks such as zoom fatigue. This paper addresses the quality of user experience by exploring an enhanced system concept with the capability of conveying gaze and attention. Gazing Heads is a round-table virtual meeting concept that uses only a single screen per participant. It enables direct eye contact, and signals gaze via controlled head rotation. The technology to realise this novel concept is not quite mature though, so we built a camera-based simulation for four simultaneous videoconference users. We conducted a user study comparing Gazing Heads with a conventional “Tiled View” video conferencing system, for 20 groups of 4 people, on each of two tasks. The study found that head rotation clearly conveys gaze and strongly enhances the perception of attention. Measurements of turn-taking behaviour did not differ decisively between the two systems (though there were significant differences between the two tasks). A novel insight in comparison to prior studies is that there was a significant increase in mutual eye contact with Gazing Heads, and that users clearly felt more engaged, encouraged to participate and more socially present. Overall, participants expressed a clear preference for Gazing Heads. These results suggest that fully implementing the Gazing Heads concept, using modern computer vision technology as it matures, could significantly enhance the experience of videoconferencing.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Heidelberg","institution":"University of Heidelberg","dsl":""}],"personId":186052},{"affiliations":[{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Interactive Media Lab Dresden"},{"country":"Germany","state":"","city":"Dresden","institution":"TUD Dresden University of Technology","dsl":"Centre for Tactile Internet with Human-in-the-Loop (CeTI)"}],"personId":185451},{"affiliations":[{"country":"United Kingdom","state":"GB","city":"Cambridge","institution":"Clare Hall, Cambridge","dsl":""}],"personId":182726},{"affiliations":[{"country":"Germany","state":"","city":"Heidelberg","institution":"IWR","dsl":"Uni Heidelberg"}],"personId":185242}]},{"id":189054,"typeId":13950,"title":"Human-Computer Interaction for the Mass Customization of 3D-Printed Eyewear: Designing an Aesthetically Fitting System and Its Co-creation Services","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3706659"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=FFY_V0kV0vQ"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25j-8350","source":"PCS","trackId":13415,"tags":[],"keywords":[],"sessionIds":[191127],"eventIds":[],"abstract":"This project explores the integration of mass customization and 3D printing in eyewear design to develop an aesthetically fitting system that harmonizes eyeglass frames with individual facial features.

While these headsets have made impressive strides in audio-visual immersion over the past half-century, XR interactions remain almost completely absent of appropriately expressive tactile sensations. At present, even mainstream consumer systems rely on vibrotactile haptic actuators in the controllers, which are inherently limited to clicks and buzzes — an exceedingly limited range of expressivity with which to represent the rich tactile world. \r\n\r\nRealizing the holistic promise of XR requires full-body haptic immersion, just as much as it requires full audio-visual immersion. To frame critical design considerations in haptics research, I propose an immersion-practicality tradeoff model. These competing objectives underscore the inherent tension between providing rich sensory feedback (often e.g. costly, bulky), while maintaining consumer feasibility and usability (e.g., low cost, easy to use). Under this framework, I sought to identify and build Pareto-efficient haptic systems where the haptic approach is aligned with humans' sensorimotor system. I present three published projects that embody my design approach with tactile haptics to different regions of the body. My proposed future work extends this framework to the other major dimensions of haptics (kinesthetic/force feedback). These systems serve as probes into my research approach and advance the vision of practical, immersive, full-body haptics.","authors":[{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"School of Computer Science"}],"personId":186048}]},{"id":189081,"typeId":13945,"title":"VibWalk: Mapping Lower-limb Haptic Experiences of Everyday Walking","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714254"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=BoNekarYCy8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8778","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195077],"eventIds":[],"abstract":"Walking is among the most common human activities where the feet can gather rich tactile information from the ground.

Based on these insights, we present design guidelines to ensure users can effectively engage in the creative process, considering their musical expertise.\r\n","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Gwangju","institution":"Gwangju Institute of Science and Technology","dsl":"School of Integrated Technology/Soft Computing & Interaction Laboratory"}],"personId":182679},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Gwangju","institution":"Gwangju Institute of Science and Technology","dsl":"AI graduated school"}],"personId":186665},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Gwangju ","institution":"Gwangju Institute of Science and Technology","dsl":""}],"personId":185807},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Gwangju","institution":"Gwangju Institute of Science and Technology","dsl":"School of Integrated Technology"},{"country":"Korea, Republic of","state":"","city":"Gwangju","institution":"Gwangju Institute of Science and Technology","dsl":"Artificial Intelligence Graduate School"}],"personId":183359}]},{"id":189088,"typeId":13945,"title":"The Amplifying Effect of Explainability in AI-assisted Decision-making in Groups","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713534"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=FxdTwb2IUyo"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8301","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195031],"eventIds":[],"abstract":"In the era of artificial intelligence, AI-assisted decision-making has become a common paradigm.

We introduce NightLight, a new sensing approach that leverages the ubiquity of smartphones by re-appropriating the built-in light sensor ---traditionally used to adapt screen brightness---to sense pedestrian nighttime lighting conditions. We validated our technique through in-lab and street-based evaluations characterizing performance across phone orientation, phone model, and varying light levels demonstrating the ability to aggregate and map pedestrian-oriented light levels with unaltered smartphones. Additionally, to examine the impact of light level data on pedestrian route choice, we conducted a qualitative user study with 13 participants using a standard map vs. one with pedestrian lighting data from NightLight Our findings demonstrate that people changed their routes in preference of well-light routes during nighttime walking. Our work has implications for expanding personalized navigation and pedestrian route choice and passive urban sensing.

Through this study, we: (1) underscore recognizing specific user groups in death-related technologies, (2) explore death as an existential and disorienting grounds within HCI, (3) extend post-userist concepts to consider the notion of ``use'' after death, and (4) identify the liminal space between physical and digital legacies as a meaningful realm to explore.","authors":[{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":"School of Interactive Computing"},{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":""}],"personId":184830},{"affiliations":[{"country":"Korea, Republic of","state":"Seoul","city":"Seoul","institution":"Yonsei University","dsl":""}],"personId":185446},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":""}],"personId":187624},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":""}],"personId":187668},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":""}],"personId":186973},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Underwood International College, Yonsei University","dsl":""}],"personId":186942},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":""}],"personId":184029},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"Information and Interaction Design "}],"personId":186781}]},{"id":189113,"typeId":13945,"title":"Responsibility Attribution in Human Interactions with Everyday AI Systems","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713126"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9841","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195134],"eventIds":[],"abstract":"How do individuals perceive AI systems as responsible entities in everyday collaborations between humans and AI?

Using an online survey, this paper explores how volunteers in online citizen science experience satisfaction and dissatisfaction of needs for autonomy, competence, and relatedness, and how this relates to both their behaviour and motivations to take part. Results suggest that participation in online citizen science on the Zooniverse relates primarily to the satisfaction than dissatisfaction of needs, suggesting that taking part is psychologically beneficial to volunteers. Autonomy is the most supported need and relatedness the least. Whilst results are positive, we observe that measures of need satisfaction must be contextually relevant, especially given the complex nature of autonomy in online citizen science, to aid in further understanding of these relationships.

We discuss how scrutinizing the work of wizards can inform explorative Wizard-of-Oz paradigms, the design of multi-agent robot systems, and the operation of urban robots from a distance.","authors":[{"affiliations":[{"country":"Sweden","state":"","city":"Linköping","institution":"Linköping University","dsl":"Department of Culture and Society"}],"personId":185382},{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Cornell Tech","dsl":"Computer Science"}],"personId":185810},{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Cornell Tech","dsl":"Information Science"}],"personId":185947}]},{"id":189126,"typeId":13945,"title":"Fictional Failures and Real-World Lessons: Ethical Speculation Through Design Fiction on Emotional Support Conversational AI","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713322"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=taY6HAjcPbg"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4156","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195023],"eventIds":[],"abstract":"Conversational artificial intelligence (CAI), which replicates human-to-human interaction as human-to-machine, is increasingly developed to address insufficient access to healthcare.

Second, we propose a transferable iterative reflection (TIR) module that augments both prompting-based and finetuning-based large language models (LLMs) for simulating learning behaviors. Our comprehensive experiments show that TIR enables the LLMs to perform more accurate student simulation than classical deep learning models, even with limited demonstration data. Our TIR approach better captures the granular dynamism of learning performance and inter-student correlations in classrooms, paving the way towards a ``digital twin'' for online education.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California San Diego","dsl":"Department of Electrical and Computer Engineering"}],"personId":183860},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California, San Diego","dsl":""}],"personId":187172},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California, San Diego","dsl":""}],"personId":185925},{"affiliations":[{"country":"United States","state":"California","city":"La Jolla","institution":"University of California, San Diego","dsl":""}],"personId":187509},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"University of Pennsylvania","dsl":""}],"personId":187817},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California San Diego","dsl":"Department of Electrical and Computer Engineering"}],"personId":187027}]},{"id":189138,"typeId":13945,"title":"Lost in Moderation: How Commercial Content Moderation APIs Over- and Under-Moderate Group-Targeted Hate Speech and Linguistic Variations","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713998"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=iX8HxtXevtA"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9858","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195019],"eventIds":[],"abstract":"Commercial content moderation APIs are marketed as scalable solutions to combat online hate speech.

To assess such risks, this paper introduces a framework for auditing black-box NLP systems. Using the framework, we systematically evaluate five widely used commercial content moderation APIs. Analyzing five million queries based on four datasets, we find that APIs frequently rely on group identity terms, such as ``black'', to predict hate speech. While OpenAI's and Amazon's services perform slightly better, all providers under-moderate implicit hate speech, which uses codified messages, especially against LGBTQIA+ individuals. Simultaneously, they over-moderate counter-speech, reclaimed slurs and content related to Black, LGBTQIA+, Jewish, and Muslim people. We recommend that API providers offer better guidance on API implementation and threshold setting and more transparency on their APIs' limitations. \r\n\r\n\\noindent \\textit{\\textbf{Warning}: This paper contains offensive and hateful terms and concepts.

Our exploration reveals that the incorporation of optical flow techniques to extract motion information between consecutive frames for the index finger and palm leads to a significant improvement in touch status determination. By doing so, our CNN model achieves 97.0% recognition accuracy and a 96.1% F1 score. In usability evaluation, we compare Palmpad with Quest's inherent hand gesture algorithms.

We introduce Script&Shift, a layered interface paradigm designed to minimize these disruptions by aligning writing intents with LLM capabilities to support diverse content development and rhetorical strategies. By bridging envisioning, semantic, and articulatory distances, Script&Shift interactions allow writers to leverage LLMs for various content development tasks (scripting) and experiment with diverse organization strategies while tailoring their writing for different audiences (shifting). This approach preserves creative control while encouraging divergent and iterative writing. Our evaluation shows that Script&Shift enables writers to creatively and efficiently incorporate LLMs while preserving a natural flow of composition.","authors":[{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":""}],"personId":187438},{"affiliations":[{"country":"United States","state":"California","city":"Stanford","institution":"Stanford University","dsl":"Graduate School of Education"}],"personId":184183},{"affiliations":[{"country":"United States","state":"California","city":"Stanford","institution":"Stanford University","dsl":""}],"personId":184026}]},{"id":189177,"typeId":13945,"title":"\"Ronaldo's a poser!\": How the Use of Generative AI Shapes Debates in Online Forums","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713829"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=Tmq9Ayxix3w"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4376","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195017],"eventIds":[],"abstract":"Online debates can enhance critical thinking but may escalate into hostile attacks.

Therefore, AR can enhance IAMs, but its effects may be modest and short-lived in most cases.

Our findings identified two main sources of seams: technical glitches and identity collapses, where VTubers act inconsistently with their virtual personas, revealing aspects of their real selves. These seams played a pivotal role in shaping diverse fan engagements, with some valuing authenticity linked to real identities, while others prioritized the coherence of virtual personas.

We found that despite e-NAM's intended benefits, mandis continue to be the preferred mode of transaction for trading agricultural commodities. We demonstrate that these two agricultural marketplaces foster different meanings of information transparency, efficiency, and participation among stakeholders. In agrarian societies dominated by smallholder farmers, such as India, social collectives and non-economic relationships are crucial for providing safety and risk mitigation when dealing with perishable commodities like onions. We argue that e-NAM fails because its digital intermediation prioritizes an ahistorical and depoliticized free-market approach, which treats farmers (and traders) as independent units driven solely by the economic logic of demand and supply, disconnecting them from their historical and political agrarian social class.","authors":[{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":183361},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":186316},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"Faculty of Information"}],"personId":184522}]},{"id":189218,"typeId":13945,"title":"CT4ALL: Towards Putting Teachers in the Loop to Advance Automated Computational Thinking Metric Assessments in Game-Based Learning","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713368"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=vr9FtipNCEw"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8718","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195012],"eventIds":[],"abstract":"Computational thinking (CT) is essential for the 21st century learner.

This research outlines the design space for post-cancer sexual health by providing specific design directions (“what”) and ways for designing them (“how”), while advancing the broader discourse on intimacy and design within HCI.","authors":[{"affiliations":[{"country":"Netherlands","state":"","city":"Delft","institution":"Delft University of Technology","dsl":"Industrial Design Engineering"}],"personId":183669},{"affiliations":[{"country":"Netherlands","state":"","city":"Delft","institution":"Delft University of Technology","dsl":"Industrial Design Engineering"}],"personId":187491},{"affiliations":[{"country":"Netherlands","state":"","city":"Rotterdam","institution":"Independent Visual Artist","dsl":""}],"personId":187117},{"affiliations":[{"country":"Netherlands","state":"","city":"Delft","institution":"Delft University of Technology","dsl":"Industrial Design Engineering"}],"personId":185412}]},{"id":189230,"typeId":13945,"title":"\"Comforting and Small Like a House Cat, Big and Intimidating Like a Bodyguard\": How Women Perceive and Envision AI Companions as a New Harassment Mitigation Approach in Social VR","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713473"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=mT0usXyCMAE"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-7863","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195049],"eventIds":[],"abstract":"Companionship is crucial for people's everyday psychological well-being.

This research instead explores the malleable overview-detail interface, one that end-users can customize to address individual needs. Our content analysis of overview-detail interfaces uncovered three dimensions of variation: content, composition, and layout, enabling us to develop customization techniques along these dimensions. For content, we developed Fluid Attributes, a set of techniques enabling users to show and hide attributes between views and leverage AI to manipulate, reformat, and generate new attributes. For composition and layout, we provided solutions to compose multiple overviews and detail views and transform between various overview and overview-detail layouts. A user study on our techniques implemented in two design probes revealed that participants produced diverse customizations and unique usage patterns, highlighting the need and broad applicability for malleable overview-detail interfaces.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California San Diego","dsl":""}],"personId":183857},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California San Diego","dsl":""}],"personId":185550},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California, San Diego","dsl":""}],"personId":187843},{"affiliations":[{"country":"United States","state":"California","city":"San Diego","institution":"University of California, San Diego","dsl":"Department of Cognitive Science and Design Lab"}],"personId":183602}]},{"id":189244,"typeId":13945,"title":"XCam: Mixed-Initiative Virtual Cinematography for Live Production of Virtual Reality Experiences","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713305"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=fWzq6Zjn4U4"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-5210","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195021],"eventIds":[],"abstract":"VR is often utilized for organizing virtual events such as meetings, conferences, and concerts; however, support for live production is lacking in most existing VR tools.

Whenever scaffold lines are edited, our system solves for a scaffold line configuration that preserves inter-scaffold relationships. The shape and detail curves are then deformed to match the new scaffold lines. This allows exploratory product design in which a simple template scaffolded 3D drawing is modified and detailed---and further modified---to create a variety of designs.

We present a technique which preserves the temporal and spatial alignment of the original composition when automatically retargeting speech-driven video compositions. It can transfer graphics between both similar and dissimilar performances, including those varying in speech and gesture. We use a large language model for transcript-based temporal alignment and integer programming for spatial alignment. Results from retargeting between 51 pairs of performances show that we achieve a temporal alignment success rate of 90% compared to hand-generated ground truth compositions.

This paper presents our efforts in iterating on Beacon’s hardware and software to enable at-home use, then reports on an at-home deployment with 21 patients taking measurements over 6 weeks. We found that measurements were stable despite being taken at different times and in different environments. Finally, through interviews with 15 patients and 5 hepatologists, we report on participant experiences with Beacon, preferences around how CFF data should be presented, and the role of caregivers in helping patients manage their condition. Informed by our experiences with Beacon, we further discuss design implications for home health devices.","authors":[{"affiliations":[{"country":"United States","state":"Washington","city":"Seattle","institution":"University of Washington","dsl":"Paul G.

This raises concerns about how intimate data is governed, used, and shared. To understand user attitudes towards data sharing in intimate contexts, we then conducted a survey exploring factors influencing user data sharing preferences. Our findings reveal that users desire transparency and control mechanisms and that their willingness to share data is influenced by contextual factors, including the third parties involved, the purposes of data collection, and the sensitivity of the data. Building on these findings, we worked with users to co-design ten concrete mechanisms for enhancing data transparency and control throughout fertility tracker product usage lifecycles.

We also identified five strategies patients adopted to mitigate asymmetries and access top-tier medical resources, illustrating these strategies as subnetworks within the broader health information-seeking network and outlining their advantages and challenges.","authors":[{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Tsinghua University","dsl":"Global Innovation Exchange"}],"personId":187489},{"affiliations":[{"country":"China","state":"","city":"Hong Kong","institution":"City University of Hong Kong","dsl":"Department of Computer Science"}],"personId":183889},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Tsinghua University","dsl":"Department of Computer Science and Technology"}],"personId":183231},{"affiliations":[{"country":"United States","state":"New York","city":"New York City","institution":"Columbia University","dsl":"Department of Biomedical Informatics"}],"personId":187592},{"affiliations":[{"country":"China","state":"","city":"Hong Kong","institution":"City University of Hong Kong","dsl":"Department of Computer Science"}],"personId":183014},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Tsinghua University","dsl":"Department of Computer science and Technology"},{"country":"China","state":"","city":"Xining","institution":"Qinghai University","dsl":""}],"personId":187044}]},{"id":189338,"typeId":13945,"title":"Characterizing LLM-Empowered Personalized Story Reading and Interaction for Children: Insights From Multi-Stakeholders' Perspective","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713275"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=mOOor4hOCp0"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8910","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195132],"eventIds":[],"abstract":"Personalized interaction is highly valued by parents in their story-reading activities with children. While AI-empowered story-reading tools have been increasingly used, their abilities to support personalized interaction with children are still limited. Recent advances in large language models (LLMs) show promise in facilitating personalized interactions, but little is known about how to effectively and appropriately use LLMs to enhance children's personalized story-reading experiences. This work explores this question through a design-based study. Drawing on a formative study, we designed and developed StoryMate, an LLM-empowered personalized interactive story-reading tool for children, following an empirical study with children, parents, and education experts. Our participants valued the personalized features in StoryMate, and also highlighted the need to support personalized content, guiding mechanisms, reading context variations, and interactive interfaces. Based on these findings, we propose a series of design recommendations for better using LLMs to empower children's personalized story reading and interaction.","authors":[{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"East China Normal University","dsl":""}],"personId":183391},{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"East China Normal University","dsl":"School"}],"personId":186681},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Boston","institution":"Northeastern University","dsl":""}],"personId":183744},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Boston","institution":"Northeastern University","dsl":""}],"personId":183270},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Lexington","institution":"Lexington High School","dsl":""}],"personId":187259},{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"Hong Kong University of Science and Technology","dsl":""}],"personId":183431},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":""}],"personId":183932},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Boston","institution":"Northeastern University","dsl":""}],"personId":186046},{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"East China Normal University","dsl":"School of Computer Science and Technology"}],"personId":185192},{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"East China Normal University","dsl":"School of Computer Science and Technology"}],"personId":188159}]},{"id":189339,"typeId":13945,"title":"The Sharply Decreasing Disruptiveness of HCI","award":"HONORABLE_MENTION","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713917"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=ZECDgewfvhI"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-6975","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195055],"eventIds":[],"abstract":"How creative is HCI research?

Despite the rapid advancements of automatic font generation models, existing methods require users to prepare pre-designed characters with target styles using font-editing software, which poses a problem for non-expert users. To address this limitation, we propose FontCraft, a system that enables font generation without relying on pre-designed characters. Our approach integrates the exploration of a font-style latent space with human-in-the-loop preferential Bayesian optimization and multimodal references, facilitating efficient exploration and enhancing user control. Moreover, FontCraft allows users to revisit previous designs, retracting their earlier choices in the preferential Bayesian optimization process.

These systems typically rely on multilingual large language models (LLMs), providing globalized workers the ability to revise or create diverse forms of content in different languages. However, there is substantial evidence indicating that the performance of multilingual LLMs varies between languages. Users who employ writing assistance for multiple languages are therefore susceptible to disparate output quality. Importantly, recent research has shown that people tend to generalize algorithmic errors across independent tasks, violating the behavioral axiom of choice independence. In this paper, we analyze whether user utilization of novel writing assistants in a charity advertisement writing task is affected by the AI's performance in a second language. Furthermore, we quantify the extent to which these patterns translate into the persuasiveness of generated charity advertisements, as well as the role of peoples’ beliefs about LLM utilization for their donation choices. Our results provide evidence that writers who engage with an LLM-based writing assistant violate choice independence, as prior exposure to a Spanish LLM reduces subsequent utilization of an English LLM. While these patterns do not affect the aggregate persuasiveness of the generated advertisements, people's beliefs about the source of an advertisement (human versus AI) do. In particular, Spanish-speaking female participants who believed that they read an AI-generated advertisement strongly adjusted their donation behavior downwards. Furthermore, people are generally not able to adequately differentiate between human-generated and LLM-generated ads. Our work has important implications on the design, development, integration, and adoption of multilingual LLMs as assistive agents—particularly in writing tasks.","authors":[{"affiliations":[{"country":"Netherlands","state":"Zuid Holland","city":"Rotterdam","institution":"Technical University of Delft","dsl":""}],"personId":182771},{"affiliations":[{"country":"Germany","state":"","city":"Goettingen","institution":"University of Goettingen","dsl":""}],"personId":187877},{"affiliations":[{"country":"Netherlands","state":"","city":"Delft","institution":"Delft University of Technology","dsl":"Web Information Systems"}],"personId":184352}]},{"id":189360,"typeId":13945,"title":"Maintaining \"Balanced\" Conflict: Proactive Intervention Strategies of AI Voice Agents in Online Collaboration of Temporary Design Teams","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713457"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=SsgfO7JDYgU"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-5658","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[191355],"eventIds":[],"abstract":"Temporary teams are important in modern work but often struggle with interpersonal factors that hinder consensus-driven tasks, especially in design teams where effective discussion and execution are critical.

Despite advancements, training machine to capture regions of interest for comprehensive scene understanding, like human perception and reasoning, remains a significant challenge. This study introduces a novel framework, Human Attention-based Explainable Guidance for Intelligent Vehicle Systems (AEGIS). \r\nAEGIS utilizes human attention, converted from eye-tracking, to guide reinforcement learning (RL) models to identify critical regions of interest for decision-making. AEGIS uses a pre-trained human attention model to guide reinforcement learning (RL) models to identify critical regions of interest for decision-making. By collecting 1.2 million frames from 20 participants across six scenarios, AEGIS pre-trains a model to predict human attention patterns. The learned human attention guides the RL agent’s focus on task-relevant objects, prioritizes critical instances, enhances robustness in unseen environments, and leads to faster learning convergence. This approach enhances interpretability by making machine attention more comparable to human attention and thus enhancing the RL agent’s performance in diverse driving scenarios.

This workshop will explore emerging practices in participatory algorithm design – or the use of public participation and community engagement - in the scoping, design, adoption, and implementation of public sector algorithms.","authors":[{"affiliations":[{"country":"United States","state":"Wisconsin","city":"Madison","institution":"University of Wisconsin-Madison","dsl":"The Information School"}],"personId":182654},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"UC-Berkeley","dsl":"School of Information"}],"personId":183441},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":""}],"personId":184842},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"University of California, Berkeley","dsl":"School of Information"}],"personId":185197},{"affiliations":[{"country":"United States","state":"Wisconsin","city":"Madison","institution":"University of Wisconsin - Madison","dsl":"The Information School"}],"personId":183348},{"affiliations":[{"country":"United States","state":"Texas","city":"Austin","institution":"University of Texas at Austin","dsl":"School of Information"}],"personId":186484},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"School of Computer Science"}],"personId":184959},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"Faculty of Information"}],"personId":184153},{"affiliations":[{"country":"United States","state":"Maryland","city":"College Park","institution":"University of Maryland College Park","dsl":"College of Information Studies"}],"personId":185219},{"affiliations":[{"country":"United States","state":"California","city":"La Jolla","institution":"UC San Diego","dsl":"Department of Communication"}],"personId":186451},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"UC Berkeley","dsl":"School of Information"}],"personId":186937},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"HCI Institute"}],"personId":183646}]},{"id":189392,"typeId":13948,"title":"Purposeful XR: Affordances, Challenges, and Speculations for an Ethical Future","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3706739"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25q-6728","source":"PCS","trackId":13413,"tags":[],"keywords":[],"sessionIds":[190172],"eventIds":[],"abstract":"Education, healthcare, poverty, and equity are just some of the social problems in which XR researchers leverage augmented reality, virtual reality, and mixed reality to create novel solutions.

This paper investigates the behaviors, challenges, and security practices of cryptocurrency users regarding seed phrase management. We conducted a mixed-methods study comprising semi-structured interviews with 20 participants and a comprehensive survey of 643 respondents. Our findings reveal significant gaps in users' understanding and practices around seed phrase security \r\nand the circumstances under which users share their seed phrases. We also explore users' mental models of shared accounts and strategies for handling cryptocurrency assets in the event of death. We found that the majority of our participants harbored significant misconceptions about seed phrases that could expose them to significant security risks --- e.g., only 43% could correctly identify an image of a seed phrase, many believed they could reset their seed phrase if they lost them. Moreover, only a minority have engaged in any estate planning for their crypto assets. By identifying these challenges and behaviors, we provide actionable insights for the design of more secure and user-friendly cryptocurrency wallets, ultimately aiming to enhance user confidence in managing their crypto assets reduce their exposure to scams and accidental loss of assets, and simplify the creation of bequeathment plans.","authors":[{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human Computer Interaction Institute"}],"personId":187615},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":""}],"personId":183505},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human Computer Interaction Institute"}],"personId":186307},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute"}],"personId":182983},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute"}],"personId":186415}]},{"id":189397,"typeId":13945,"title":"Exploring the Design Space of Real-time LLM Knowledge Support Systems: A Case Study of Jargon Explanations","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714262"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=QQQpSS4Keh0"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-2003","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[197232],"eventIds":[],"abstract":"Knowledge gaps often arise during communication due to diverse backgrounds, knowledge bases, and vocabularies.

Prior attempts to map the risks of LLMs have not been tailored to education specifically, even though it is a unique domain in many respects: from its population (students are often children, who can be especially impacted by technology) to its goals (providing the correct answer may be less important for learners than understanding how to arrive at an answer) to its implications for higher-order skills that generalize across contexts (e.g., critical thinking and collaboration). We conducted semi-structured interviews with six edtech providers representing leaders in the K-12 space, as well as a diverse group of 23 educators with varying levels of experience with LLM-based edtech. Through a thematic analysis, we explored how each group is anticipating, observing, and accounting for potential harms from LLMs in education. We find that, while edtech providers focus primarily on mitigating technical harms, i.e., those that can be measured based solely on LLM outputs themselves, educators are more concerned about harms that result from the broader impacts of LLMs, i.e., those that require observation of interactions between students, educators, school systems, and edtech to measure. Overall, we (1) develop an education-specific overview of potential harms from LLMs, (2) highlight gaps between conceptions of harm by edtech providers and those by educators, and (3) make recommendations to facilitate the centering of educators in the design and development of edtech tools.","authors":[{"affiliations":[{"country":"United States","state":"New York","city":"Ithaca","institution":"Cornell University","dsl":"Information Science"}],"personId":186298},{"affiliations":[{"country":"United States","state":"New York","city":"Ithaca","institution":"Cornell University","dsl":""}],"personId":183766},{"affiliations":[{"country":"United States","state":"New York","city":"Ithaca","institution":"Cornell University","dsl":"Department of Information Science"}],"personId":185059}]},{"id":189410,"typeId":13945,"title":"SpineLoft: Interactive Spine-based 2D-to-3D Modeling","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713439"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=L91pXvX9wIo"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-5728","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[191344],"eventIds":[],"abstract":"3D artists (professionals and novices alike) often take inspiration from sketches or photos to guide their designs.

Our results show that the Point of Subjective Synchrony (PSS) is influenced by frequency, whereas the Window of Subjective Synchrony (WSS) is not. Variations in SOA induce adaptive gaze behavior in response to audiovisual latencies, while pupil diameter increases with increasing SOA, suggesting a higher cognitive load for successive unisensory rather than integrated events.

In addition, the choice of frequencies may help to mask latencies, enhance the experience of synchrony and thus support feelings of closeness and intimacy in virtual interaction.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Weimar","institution":"Bauhaus-Universität Weimar","dsl":"Usability"}],"personId":188181},{"affiliations":[{"country":"Germany","state":"","city":"Weimar","institution":"Bauhaus-Universität Weimar","dsl":"VR and Visualisation Research Group"}],"personId":183941},{"affiliations":[{"country":"Germany","state":"","city":"Weimar","institution":"Bauhaus-Universität","dsl":""}],"personId":186258},{"affiliations":[{"country":"Germany","state":"","city":"Weimar","institution":"Bauhaus-Universität Weimar","dsl":"Virtual Reality and Visualization Research Group"}],"personId":182976},{"affiliations":[{"country":"Germany","state":"","city":"Weimar","institution":"Bauhaus-Universität Weimar","dsl":""}],"personId":188016},{"affiliations":[{"country":"Germany","state":"","city":"Weimar","institution":"Bauhaus-Universität Weimar","dsl":"Usability"}],"personId":187403}]},{"id":189417,"typeId":13945,"title":"Social Media for Activists: Reimagining Safety, Content Presentation, and Workflows","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713351"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=KZR43tU_bok"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-3300","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195125],"eventIds":[],"abstract":"Social media is central to activists, who use it internally for coordination and externally to reach supporters and the public.

Predefined stylistic choices enable non-experts to produce guideline-compliant tactile charts quickly. Expert users can override defaults to tailor customizations for their intended audience.

We identify several pathways or \"theories of change\" through which documentation can enhance governance, including informing stakeholders about AI risks and applications, facilitating collaboration, encouraging ethical deliberation, and supporting best practices. However, empirical findings reveal significant challenges for practitioners, such as insufficient incentives and resources, structural and organizational communication barriers, interpersonal and organizational constraints to ethical action, and poor integration with existing workflows. These challenges often hinder the realization of the possible benefits of documentation. We also highlight key considerations for organizations when designing documentation, such as determining the appropriate level of detail and balancing automation in the process.

By unpacking a number of such sports-specific skills and data practices involved in long-distance running, six themes for novel perspectives on the design of sports technology are discussed.","authors":[{"affiliations":[{"country":"Sweden","state":"","city":"Stockholm","institution":"Stockholm University","dsl":""}],"personId":185668}]},{"id":189469,"typeId":13945,"title":"How Scientists Use Large Language Models to Program","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713668"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=NAzuF6cv1T8"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-1358","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195115],"eventIds":[],"abstract":"Scientists across disciplines write code for critical activities like data collection and generation, statistical modeling, and visualization.

Leveraging the immersive capabilities of VR, AR, and LLMs to create realistic interactions and environments, we developed eight interactive prototypes for various stress related scenarios (e.g. public speaking, interpersonal conflict) across design dimensions of modality, interactivity, and mental health guidance in order to conduct prototype-driven semi-structured interviews with 19 participants.

We outline key design needs for developing social simulation for self-care needs, and identify important considerations including risks of trauma from hyper-realism, distrust of LLM-recommended timing for mental health recommendations, and the value of accessibility for self-care interventions.\r\n","authors":[{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human-Computer Interaction Institute, School of Computer Science"}],"personId":186418},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"Accessibility Lab"}],"personId":183574},{"affiliations":[{"country":"United States","state":"New York","city":"New York","institution":"Barnard College","dsl":""}],"personId":187326},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University","dsl":"Human Computer Interaction Institute"}],"personId":183823}]},{"id":189497,"typeId":13945,"title":"Sticking With Electronics for Crafting Practices: An Inclusive Approach to Promote Making Literacy Among Older Adults","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714234"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=Q1Fncsa_9_U"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-4606","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195084],"eventIds":[],"abstract":"Making activities have been shown to offer potential for inclusive access to digital literacy amongst marginalized groups, but research exploring such approaches with older adults is still scarce.

By providing objective and unobtrusive measures of social interactions, this study contributes to enhancing the understanding and improvement of social VR experiences.","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":""}],"personId":187009},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"KAIST","dsl":"Graduate School of Culture Technology"}],"personId":186515}]},{"id":189522,"typeId":13945,"title":"Creating Furniture-Scale Deployable Objects with a Computer-Controlled Sewing Machine","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713735"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=y7TktvS-8uM"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-2638","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195053],"eventIds":[],"abstract":"We introduce a novel method for fabricating functional flat-to-shape objects using a large computer-controlled sewing machine (11 ft / 3.4m wide), a process that is both rapid and scalable beyond the machine's sewable area.

WhatELSE provides three views (narrative pivot, outline, and variants) to help authors understand the narrative space and corresponding tools leveraging linguistic abstraction to control the boundaries of the narrative space. Taking innovative LLM-based narrative planning approaches, WhatELSE further unfolds the narrative space into executable game events. Through a user study (N=12) and technical evaluations, we found that WhatELSE enables authors to perceive and edit the narrative space and generates engaging interactive narratives at play-time.\r\n","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"Autodesk Research","dsl":""},{"country":"United States","state":"Indiana","city":"West Lafayette","institution":"Purdue University","dsl":"Computer Science"}],"personId":187347},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"Autodesk Research","dsl":""}],"personId":186140},{"affiliations":[{"country":"United States","state":"California","city":"San Francisco","institution":"Autodesk Research","dsl":""}],"personId":182780}]},{"id":189536,"typeId":13945,"title":"Design for Civic Quality of Life Things","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713186"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=NL6uWt781L4"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-1302","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195032],"eventIds":[],"abstract":"This paper reports on inquiry into the design decisions that shape how quality of life issues are reported and government service requests managed in a large and densely populated city in the northeastern US.

Considering the individual differences, we use optimal transport to compute the muscle synergy similarity between users and experts. This approach allows users to model their muscle usage after the expert whose synergy is closest. Based on the muscle synergy differences between the expert and the user, EMS is applied to the muscles that need activation. As a result, users can practice putting with increased awareness of the muscles targeted by EMS, resulting in changes in muscle synergy and improved performance.

Abstraction alignment externalizes domain-specific human knowledge as an abstraction graph, a set of pertinent concepts spanning levels of abstraction. Using the abstraction graph as a ground truth, abstraction alignment measures the alignment of a model’s behavior by determining how much of its uncertainty is accounted for by the human abstractions. By aggregating abstraction alignment across entire datasets, users can test alignment hypotheses, such as which human concepts the model has learned and where misalignments recur. In evaluations with experts, abstraction alignment differentiates seemingly similar errors, improves the verbosity of existing model-quality metrics, and uncovers improvements to current human abstractions.","authors":[{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"Massachusetts Institute of Technology","dsl":"CSAIL"}],"personId":183551},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"Massachusetts Institute of Technology","dsl":"CSAIL"}],"personId":183849},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"IBM Research AI","dsl":""}],"personId":186253},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"MIT","dsl":"CSAIL"}],"personId":184686}]},{"id":189586,"typeId":13945,"title":"Enhancing Deliberativeness: Evaluating the Impact of Multimodal Reflection Nudges","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3714189"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=7b3hyTJ-txI"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-3716","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195063],"eventIds":[],"abstract":"Nudging participants with text-based reflective nudges enhances deliberation quality on online deliberation platforms.

Our technique allows for the realization of more precise and complex deformations. We implemented mapping of the ear’s contour, thereby creating illusions of different ear shapes, such as elf ears and dog ears.

In this study, we conducted an ethnographic case study on the City of Toronto’s homelessness system’s data practices across different critical points. We show how the City’s data practices offer standardized processes for client care but frontline workers also engage in heuristic decision-making in their work to navigate uncertainties, client resistance to sharing information, and resource constraints. From these findings, we show the temporality of client data which constrain the validity of predictive AI models. Additionally, we highlight how the City adopts an iterative and holistic client assessment approach which contrasts to commonly used risk assessment tools in homelessness, providing future directions to design holistic decision-making tools for homelessness.

This paper presents our vision of linguistic diversity and inclusion in HCI research at CHI - a mélange of thoughts utilizing diverse vocabularies and languages.","authors":[{"affiliations":[{"country":"Finland","state":"","city":"Oulu","institution":"University of Oulu","dsl":"INTERACT Research Unit"}],"personId":185133},{"affiliations":[{"country":"Finland","state":"","city":"Oulu","institution":"University of Oulu","dsl":"INTERACT Research Unit"}],"personId":183944},{"affiliations":[{"country":"Finland","state":"","city":"Kuopio","institution":"Independent Researcher","dsl":""}],"personId":183982},{"affiliations":[{"country":"Finland","state":"","city":"Oulu","institution":"University of Oulu","dsl":"INTERACT"}],"personId":186762},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":"Digital Media"}],"personId":185963},{"affiliations":[{"country":"Finland","state":"Oulu","city":"Oulu","institution":"University of Oulu","dsl":"INTERACT Research Unit"}],"personId":186792},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":"Digital Media"}],"personId":184059},{"affiliations":[{"country":"Finland","state":"","city":"Oulu","institution":"University of Oulu","dsl":""}],"personId":182653},{"affiliations":[{"country":"Pakistan","state":"Punjab","city":"Lahore","institution":"Lahore University of Management Sciences","dsl":"Computer Science Department"}],"personId":183214},{"affiliations":[{"country":"United Kingdom","state":"","city":"Birmingham","institution":"Birmingham City University","dsl":"School of Computing and Digital Technology"}],"personId":187987},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology,","dsl":"Digital Media, School of Literature, Media, and Communication"}],"personId":185491},{"affiliations":[{"country":"India","state":"","city":"pune","institution":"mit institute of design","dsl":"user experience design"}],"personId":186174}]},{"id":189614,"typeId":13945,"title":"Enhancing Tactile Learning: A Co-Designed System for Supporting Speech Interaction with Multi-Part 3D Printed Models by Students who are Blind","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713706"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=8O9AQ0qjUBY"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-8387","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195035],"eventIds":[],"abstract":"3D printed models (3DPMs) are increasingly used to support the education of students who are blind or have low vision (BLV).

Over five weeks of co-design sessions, 44 participants worked alongside artists to craft four physical boxes that represent ``meaningful places.'' The physical boxes were then transformed into VR environments, allowing participants to immerse themselves in and interact with their creations from a first-person perspective. Our findings demonstrate that VR alone is insufficient in dementia care. For VR to be meaningful, it must be be part of a broader intervention that includes trust-building, sensory engagement, and creative involvement. Within this process, art-making serves as both a method and medium, providing a means of self-expression and connection to identity.

In this study, the first user performance model is presented and validated for an MTA task with multiple lanes. The model is built as an integration of the existing MTA model and the drift-diffusion model, a model of human decision-making process under time-pressure.

Mastering shooting mechanics requires consistent, precise repetition, which traditionally depends on coaching feedback and the breakdown of movements into steps during the early stages. However, due to limited coaching resources, this guidance is often unavailable, leading to ineffective and even detrimental motor learning. To bridge this gap, we propose a Standard Operating Procedure (SOP) framework grounded in expert human knowledge, or knowledge-based SOP, which allows our AI-driven system to verify and guide players' movements in real-time. Through a formative study involving interviews with 13 coaches and players, we identified key challenges faced by beginners, such as uncertainty in movement correctness and lack of guidance during unsupervised practice. Our AI system addresses these issues by providing immediate, actionable feedback using SOP tailored to individual players. In a study with 28 participants, we confirmed that our system improves shooting form, increases confidence in adjustments, and enhances self-awareness during practice. This work highlights the potential of integrating coaching expertise with AI to empower athletes with more effective tools for self-directed practice.","authors":[{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Tsing Hua University","dsl":"Institute of Service Science"}],"personId":184625},{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Tsing Hua University","dsl":"Computer Science"}],"personId":186229},{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Tsing Hua University","dsl":"Institute of Information Systems and Applications"}],"personId":186787},{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Yang Ming Chiao Tung University","dsl":"Physical Education Office"}],"personId":184827},{"affiliations":[{"country":"Taiwan","state":"","city":"Kaohsiung","institution":"Taiwan Institute of Sports Science","dsl":""}],"personId":182670},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei","institution":"Acadmia Sinica","dsl":"Institute of Information Science"}],"personId":185898},{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Tsing Hua University","dsl":"Computer Science"}],"personId":184862},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei","institution":"Taipei First Girls High School","dsl":""}],"personId":187328},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei","institution":"Academia Sinica","dsl":"Institute of Information Science"}],"personId":186394},{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Tsing Hua University","dsl":"Computer Science"}],"personId":186996},{"affiliations":[{"country":"Taiwan","state":"","city":"Hsinchu","institution":"National Tsing Hua University","dsl":"Computer Science"}],"personId":185395}]},{"id":189629,"typeId":13945,"title":"Promoting Cognitive Health in Elder Care with Large Language Model-Powered Socially Assistive Robots","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713582"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-1511","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195038],"eventIds":[],"abstract":"As the global population ages, there is increasing need for accessible technologies that promote cognitive health and detect early signs of cognitive decline.

In recent years, user experience related to risky traffic interactions has been studied using virtual simulations, desktop studies, and surveys—yet field tests have remained out of reach. In this paper, we present results from a field test of an autonomous urban passenger ferry open to public use. Specifically, we investigate two questions: (i) are passengers' safety perceptions negatively affected by interactions with risky traffic? and (ii) can simulating risky behavior in the field (so-called \"adversarial evaluation\") present a viable way to study user experience? After repeatedly sending a kayaker on a collision course with the ferry (N~=~20 interventions), we sampled naïve passengers about their experiences (intervention group; N~=~37) and compared the result to those who experienced a normal crossing (control group, N~=~178). The results favored the intervention group, which scored higher in safety perception. However, the latter also reported that there is a need for more feedback about the ferry's current state and future intentions to avoid surprises both for passengers and for other traffic. As autonomous vehicles are field-tested and deployed, the study reflects a growing need to test user experience in the operational environment. We discuss implications for design, emphasizing the use of external human-machine interfaces (eHMIs) and special considerations for the maritime domain.","authors":[{"affiliations":[{"country":"Norway","state":"","city":"TRONDHEIM","institution":"Norwegian University of Science and Technology","dsl":"Department of Design"}],"personId":187508},{"affiliations":[{"country":"Norway","state":"","city":"Oslo","institution":"Institute of Transport Economics","dsl":""},{"country":"Norway","state":"","city":"TRONDHEIM","institution":"Norwegian University of Science and Technology","dsl":"Department of Design"}],"personId":184509},{"affiliations":[{"country":"Norway","state":"","city":"TRONDHEIM","institution":"Norwegian University of Science and Technology","dsl":"Department of Design"}],"personId":183373},{"affiliations":[{"country":"Norway","state":"","city":"TRONDHEIM","institution":"Norwegian University of Science and Technology","dsl":"Department of Design"}],"personId":183988},{"affiliations":[{"country":"Norway","state":"","city":"TRONDHEIM","institution":"Norwegian University of Science and Technology","dsl":"Department of Design"}],"personId":186627},{"affiliations":[{"country":"Norway","state":"","city":"TRONDHEIM","institution":"Norwegian University of Science and Technology","dsl":"Department of Design"}],"personId":186796}]},{"id":189656,"typeId":13945,"title":"LADICA: A Large Shared Display Interface for Generative AI Cognitive Assistance in Co-located Team Collaboration","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713289"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=N15fS7JAB2Q"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9451","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195015],"eventIds":[],"abstract":"Large shared displays, such as digital whiteboards, are useful for supporting co-located team collaborations by helping members perform cognitive tasks such as brainstorming, organizing ideas, and making comparisons.

We examined three conditions: control (generic advice), perfect advice, and realistic advice, through an online survey of 489 participants on Prolific, and measured user accuracy and confidence in phishing detection with and without guidance. Our findings indicate that having advice specific to the email is more effective than generic guidance (control). Inaccuracies in the guidance can also impact user decisions and reduce detection accuracy.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"Edinburgh","institution":"University of Edinburgh","dsl":"School of Informatics"}],"personId":185188},{"affiliations":[{"country":"United Kingdom","state":"","city":"Edinburgh","institution":"University of Edinburgh","dsl":""}],"personId":187939},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"King's College London","dsl":"School of Informatics"}],"personId":183232},{"affiliations":[{"country":"United Kingdom","state":"","city":"Edinburgh","institution":"University of Edinburgh","dsl":"School of Informatics"}],"personId":187232},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"Electrical and Computer Engineering"}],"personId":182885}]},{"id":189665,"typeId":13945,"title":"Configuring Participatory Research as Give and Take Relationships: Methodological Reflections on Co-Designing Booklets with a Men Shed","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706598.3713106"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=f8tFXdE_xuM"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25b-9216","source":"PCS","trackId":13412,"tags":[],"keywords":[],"sessionIds":[195059],"eventIds":[],"abstract":"Researchers ask a lot from their study participants: data, time, attention, ideas, and (almost) anything that helps them to pursue their research goals.

This paper offers methodological reflections on a collaboration with a Men’s Shed that was tailored around both my research agenda and the interests of my community partner.

By reviewing both the trouble and the gains of this process for both partners, I argue for re-imagining community-based participatory research as an opportunity for fostering give-and-take relationships with participants. The case demonstrates the method's capacity to critically extend existing HCI work on Men’s Sheds while also making participation worthwhile for my partners.

We find that creator hearts increased the visibility of comments, and increased the amount of positive engagement they received from other users. We also find that the presence of a creator-hearted comment soon after a video is published can incentivize viewers to comment, increasing the total engagement with the video over time. We discuss how creators can use hearts to shape behavior in their communities by highlighting, rewarding, and incentivizing desired behaviors from users.

Unfortunately, humans’ most natural form of communi- cation, speech, is also one of the most difficult modalities to be understood by machines – despite, and perhaps, because it is the highest-bandwidth communication channel we possess. As signifi- cant research efforts in engineering have been spent on improving machines’ ability to understand speech, research is only begin- ning to make the same improvements in understanding how to appropriately design these speech interfaces to be user-friendly and adoptable. Issues such as variations in error rates when pro- cessing speech, and difficulties in learnability and explainability (to name a few), are often in contrast with claims of success from industry. Along with this, designers themselves are making the transition to designing for speech and voice-enabled interfaces. Recent research has demonstrated the struggle for designers to translate their current experiences in graphical user interface de- sign into speech interface design. Research has also noted the lack of any user-centered design principles or consideration for usability or usefulness in the same ways as graphical user interfaces have benefited from heuristic design guidelines.\r\nThe goal of this course is to inform the CHI community of the current state of speech and natural language research, to dispel some of the myths surrounding speech-based interaction, as well as to inform participants about currently existing design tools, meth- ods and resources for speech interfaces (and provide hands-on experience with working with them). Through this, we hope that HCI researchers and practitioners will learn how to combine re- cent advances in speech processing with user-centred principles in designing more usable and useful speech-based interactive systems.","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":""},{"country":"Canada","state":"Ontario","city":"Ottawa","institution":"Carleton University","dsl":""}],"personId":186392},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"Department of Systems Design Engineering"},{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"Technologies for Ageing Gracefully"}],"personId":184131},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"Dept. of Computer Science"}],"personId":185558}]},{"id":190041,"typeId":13940,"title":"Interaction Techniques – History, Design and Evaluation","recognitionIds":[],"isBreak":false,"importedId":"15569","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[190042],"eventIds":[],"abstract":"Interaction techniques (IxTs) are the low-level reusable building blocks out of which user interfaces are constructed.

Interested participants are invited to submit examples from their own research, which, in the workshop, will be used as a point of departure to critically reflect on and expand body-centric methods, theories and domains through the lens of body politics. Workshop outcomes will include charting future directions for body-centric research to address challenges and opportunities of acknowledging that bodies are always political in design research.","authors":[{"affiliations":[{"country":"Denmark","state":"","city":"Copenhagen","institution":"IT University of Copenhagen","dsl":"Digital Design"}],"personId":187860},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"University of the Arts London","dsl":"Creative Computing Institute"}],"personId":184294},{"affiliations":[{"country":"Denmark","state":"","city":"Copenhagen ","institution":"University of Copenhagen","dsl":"Department of Computer Science"}],"personId":182749},{"affiliations":[{"country":"Denmark","state":"","city":"Copenhagen","institution":"IT University of Copenhagen","dsl":"Digital Design"}],"personId":182677},{"affiliations":[{"country":"Denmark","state":"Denmark","city":"Copenhagen","institution":"IT University of Copenhagen","dsl":"Digital Design"}],"personId":184009},{"affiliations":[{"country":"Sweden","state":"","city":"Malmö","institution":"Malmö University","dsl":"Department of Computer Science and Media Technology"}],"personId":186667},{"affiliations":[{"country":"United States","state":"Illinois","city":"Normal","institution":"Illinois State University","dsl":"Creative Technologies Program"}],"personId":183558},{"affiliations":[{"country":"Austria","state":"","city":"Vienna","institution":"Human-Computer Interaction Group || TU Wien","dsl":"Crip Collective "}],"personId":187846},{"affiliations":[{"country":"United Kingdom","state":"","city":"London","institution":"Goldsmiths, University of London","dsl":"Computing"}],"personId":186718},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Pittsburgh","institution":"Carnegie Mellon University ","dsl":"HCI Institute"}],"personId":184987}]},{"id":190088,"typeId":13948,"durationOverride":90,"title":"Body Politics: Unpacking Tensions and Future Perspectives for Body-Centric Design Research in HCI","recognitionIds":[],"isBreak":false,"importedId":"15616","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[190091],"eventIds":[],"abstract":"Human bodies are deeply political as they carry historical and social meanings, including race, gender, sexuality, ethnicity, class, and abilities.

The workshop will include a keynote, discussion based activities and demos, and conclude with a speculative exercise, where attendees will work together to describe XR technology in the context of an ethical future.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"Stanford","institution":"Stanford University","dsl":"IXD Lab"}],"personId":183275},{"affiliations":[{"country":"United States","state":"California","city":"Santa Cruz","institution":"University of California, Santa Cruz","dsl":"Social Emotional Technology Lab"}],"personId":187342},{"affiliations":[{"country":"Netherlands","state":"","city":"Eindhoven","institution":"Eindhoven University of Technology","dsl":"Industrial Design"}],"personId":187895},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Needham","institution":"Olin College of Engineering","dsl":"Department of Computer Science"}],"personId":182973},{"affiliations":[{"country":"United States","state":"Michigan","city":"East Lansing","institution":"Michigan State University","dsl":"Department of Media and Information "}],"personId":182923}]},{"id":190181,"typeId":13948,"title":"Gathering Textiles at CHI: Convening a Meeting to Share, Make, and Speculate","recognitionIds":[],"isBreak":false,"importedId":"15709","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[190183],"eventIds":[],"abstract":"CHI is becoming home to an emerging community of researchers and practitioners engaging with textiles as a design and research material. This work is spread across a range of areas from digital fabrication to haptics. This workshop offers the opportunity for the broad community of HCI researchers to share techniques and ideas that underpin textile practices at CHI. Knitting, weaving, embroidery, hand-stitching, quilting, garment making, dying, felting, paper making, etc. offer distinct functional and aesthetic qualities while engaging similar modes of working. We propose this workshop to create a meeting place for CHI researchers engaging textiles in any capacity. We suggest a day of skill sharing and collective speculating grounded in the textiles techniques and histories of Japan.

Through this workshop, we will not only synthesize and map our existing interdisciplinary efforts and challenges in this space but also collaboratively create a roadmap detailing our developed sociotechnical solutions to address these new harms in immersive and embodied virtual spaces as a community.","authors":[{"affiliations":[{"country":"United States","state":"South Carolina","city":"Clemson","institution":"Clemson University","dsl":"School of Computing"}],"personId":186829},{"affiliations":[{"country":"Netherlands","state":"","city":"Utrecht","institution":"Utrecht University","dsl":""}],"personId":185962},{"affiliations":[{"country":"Canada","state":"British Columbia","city":"Victoria","institution":"University of Victoria","dsl":"Computer Science"}],"personId":188177},{"affiliations":[{"country":"Germany","state":"","city":"Darmstadt","institution":"TU-Darmstadt","dsl":""},{"country":"France","state":"","city":"Paris","institution":"Institut Polytechnique de Paris","dsl":"Télécom Paris - LTCI"}],"personId":188190},{"affiliations":[{"country":"United States","state":"Texas","city":"Austin","institution":"The University of Texas at Austin","dsl":"School of Information"}],"personId":187358},{"affiliations":[{"country":"United States","state":"Michigan","city":"Flint","institution":"University of Michigan-Flint","dsl":""}],"personId":186737},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"Drexel University ","dsl":"Department of Information Science, College of Computing & Informatics"}],"personId":186306},{"affiliations":[{"country":"United States","state":"Michigan","city":"Ann Arbor","institution":"University of Michigan","dsl":"School of Information"}],"personId":183163}]},{"id":190217,"typeId":13948,"title":"HCI Across Borders: Building a Collective Vision for the Future","recognitionIds":[],"isBreak":false,"importedId":"15745","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[190220],"eventIds":[],"abstract":"The HCI Across Borders (HCIxB) workshop at CHI 2025 will focus on \"Building a Collective Vision for the Future.\" HCIxB has gathered a diverse audience annually by conducting workshops and symposia since CHI 2016.

This workshop will focus on gathering and sharing lessons from experiences resisting, or attempting to resist, AI solutionism; taking stock and revisiting previous learnings from decades of work within and beyond HCI; and envisioning ways, perspectives, tools, and practices to orient ourselves and each other towards more pluralistic futures.","authors":[{"affiliations":[{"country":"United Kingdom","state":"","city":"Nottingham","institution":"University of Nottingham","dsl":"Mixed Reality Lab - School of Computer Science"}],"personId":183721},{"affiliations":[{"country":"Finland","state":"","city":"Tampere","institution":"Tampere University","dsl":"Gamification Group"}],"personId":187030},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Cambridge","institution":"IBM Research","dsl":"Human AI Collaboration"}],"personId":185044},{"affiliations":[{"country":"Sweden","state":"","city":"Stockholm","institution":"KTH Royal Institute of Technology","dsl":""}],"personId":184280},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":"School of Interactive Computing"}],"personId":185526},{"affiliations":[{"country":"United States","state":"Indiana","city":"West Lafayette","institution":"Purdue University","dsl":"Computer Graphics and Technology"}],"personId":184233},{"affiliations":[{"country":"Sweden","state":"Stockholm","city":"Huddinge","institution":"Södertörn University","dsl":"Natural Sciences, Technology and Environmental Studies"}],"personId":188174},{"affiliations":[{"country":"Argentina","state":"","city":"Bariloche","institution":"DataGénero","dsl":"DataGénero"}],"personId":183896}]},{"id":190299,"typeId":13948,"title":"Generative AI and Accessibility Workshop: Surfacing Opportunities and Risks","recognitionIds":[],"isBreak":false,"importedId":"15827","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[190303],"eventIds":[],"abstract":"The increasing use of generative AI (GAI) as an accessibility tool offers transformative opportunities, but it also introduces significant risks and barriers that remain unaddressed.

Our legs, being the largest body limbs, play an essential role in various functions such as locomotion, maintaining balance, supporting proper posture and providing ground-contact using our feet. Hence, foot augmentations offer the opportunity to augment our entire body. However, most prior research focuses on specific application areas, thus affording a research agenda to further understand the full potential of feet in designing augmentations and to contextualize it in the broader human augmentation space. To achieve this, in this workshop, we invite researchers, designers, and practitioners, novice and expert, interested in designing human and foot augmentations.

Prior work in technical AI governance has proposed agendas for governing technical components in AI development, such as data, models, and compute. However, recent calls for more sociotechnical approaches recognize the critical role of social infrastructures surrounding technical ones in shaping governance decisions and efforts. While scholars and practitioners have advocated for sociotechnical AI governance, concrete research directions in this area are only beginning to emerge. This workshop aims to gather the expertise of researchers in HCI and adjacent disciplines to chart promising paths forward for sociotechnical AI governance. To make problems in this area more tangible, we outline four core governance challenges for contributions: anticipating high-priority risks to address with governance, identifying where to focus governance efforts and who should lead those efforts, designing appropriate interventions and tools to implement governance actions in practice, and evaluating the effectiveness of these interventions and tools in context.

This workshop brings the research community together to examine various perspectives on affect, and specifically contrast Affective Interaction with Affective Computing. The aim is to discuss opportunities and limitations associated with each perspective, reconcile with advances in the science of emotion, and to speculate on future research directions.

Testing these in an urban planning task, we found that the cues placed on a user's own hand attracted their partner's gaze, which improved social closeness and emotional understanding between the partners.","authors":[{"affiliations":[{"country":"Australia","state":"South Australia","city":"Mawson Lakes","institution":"University of South Australia","dsl":"Empathic Computing Lab"}],"personId":188053},{"affiliations":[{"country":"Australia","state":"","city":"Melbourne","institution":"RMIT University","dsl":"Computing Technologies"}],"personId":187900},{"affiliations":[{"country":"Australia","state":"South Australia","city":"Adelaide","institution":"University of South Australia","dsl":"Australian Research Center for Interactive and Virtual Environment"}],"personId":192661},{"affiliations":[{"country":"United States","state":"Washington","city":"Redmond ","institution":"Meta ","dsl":"Reality Labs Research "},{"country":"Australia","state":"","city":"Mawson Lakes","institution":"Empathic Computing Lab","dsl":""}],"personId":192098},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"Electronics and Telecommunications Research Institute","dsl":""}],"personId":194023},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"Electronics and Telecommunications Research Institute","dsl":""}],"personId":192104},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Daejeon","institution":"Electronics and Telecommunications Research Institute","dsl":""}],"personId":193363},{"affiliations":[{"country":"Australia","state":"","city":"Mawson Lakes","institution":"University of South Australia","dsl":"ITMS"}],"personId":187789},{"affiliations":[{"country":"Australia","state":"SA","city":"Adelaide","institution":"University of South Australia","dsl":"IVE STEM"}],"personId":191777}]},{"id":194036,"typeId":13944,"durationOverride":120,"title":"StreetScape: Gamified Tactile Interactions for Collaborative Learning and Play","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719897"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=MSpesJUaaXM"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-1459","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196291],"eventIds":[],"abstract":"Spatial reasoning and collaboration are essential for childhood development, yet blind and visually impaired (BVI) children often lack access to tools that foster these skills.

Through three months of fieldwork and three participatory design workshops, we explored the opportunities and challenges farmers perceive in using technology to address the city's systemic food insecurity. Our findings highlight tensions where technology, rather than empowering communities, may inadvertently reinforce exploitative dynamics that remove a community's capacity for self-determination and autonomy. We contribute empirical insights and actionable principles for designing sustainable food systems that align with the values of the food sovereignty movement.

Using inductive coding and reflexive thematic analysis, we highlight how public policy is employed as a concept, revealing that the term public policy is used in numerous ways that range from being a strong voice at the forefront of the discussion to a background concept that lacks strong articulation of future scope or direction. We identify ways to strengthen connections between HCI and Policy, laying the groundwork for stronger policy discussions and outcomes.","authors":[{"affiliations":[{"country":"United States","state":"Indiana","city":"Bloomington ","institution":"Indiana University ","dsl":"Luddy School of Informatics, Computing, and Engineering"}],"personId":185662},{"affiliations":[{"country":"United States","state":"Indiana","city":"Bloomington","institution":"Indiana University","dsl":"UXP2 Lab"}],"personId":185541}]},{"id":194052,"typeId":13944,"title":"Dual-Track UX: A User Experience Evaluation Method for B2B SaaS Development","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719968"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=ImPMLeFSloU"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-9190","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196285,196462],"eventIds":[],"abstract":"User experience (UX) evaluation is critical for identifying user requirements and mitigating the risk of product failure during the development of interactive systems.

Using a 2×2 factorial design with 250 participants, the findings reveal that human agents consistently elicit stronger negative emotions than AI agents, regardless of error severity. Moreover, perceived experience moderates this relationship under specific conditions: individuals who view AI less experienced than humans exhibit stronger negative emotions toward human errors, while this effect diminishes when AI is perceived as having higher experience.

The findings provide actionable design implications for tailored digital mental health interventions, such as integrating micro-interventions into workflows to address hierarchical organizational stress and demanding workloads, recognizing emotional labor through positive rewards to support the moral and self-sacrificing police identity, and fostering mutual reliance via anonymous digital communication platforms to mitigate the effects of routine exposure to negative events. These strategies address officers’ specific challenges while aligning with their professional and cultural nuances. Although focused on Korean investigative police officers, the study offers valuable insights for designing role-specific and culturally informed solutions in other high-stress professions.","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Ulsan","institution":"Ulsan national institute of science and technology","dsl":""}],"personId":193572},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Ulsan","institution":"Ulsan National Institute of Science & Technology (UNIST)","dsl":"Graduate School of Health Science and Technology"}],"personId":193156},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Ulsan","institution":"UNIST","dsl":""}],"personId":192246},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Deajeon","institution":"KAIST","dsl":"Department of Industrial Design"}],"personId":183246},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Ulsan","institution":"Ulsan National Institute of Science & Technology (UNIST)","dsl":"Biomedical Engineering"}],"personId":191761}]},{"id":194066,"typeId":13944,"title":"\"I feel you, but. . . \": Exploring the Boundaries of Pragmatic Markers in Real-time Voice-based Conversational Agents","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719797"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=HWvz1aeVK_w"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-3739","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196298,196304],"eventIds":[],"abstract":"Although Voice-based Conversational Agents (VCAs) continue to evolve, achieving natural interaction remains challenging.

Our results show that negative attitudes evolve positively following the relatives--designed approach, which could promote a positive elderly--robot interaction and increasing social robot acceptance.","authors":[{"affiliations":[{"country":"United Kingdom","state":"UK","city":"Swansea","institution":"Swansea University","dsl":"Department of Computer Science"},{"country":"Kuwait","state":"","city":"Kuwait","institution":"Kuwait Institute for Scientific Research (KISR)","dsl":"Systems and Software Development Department "}],"personId":192788},{"affiliations":[{"country":"United Kingdom","state":"UK","city":"Swansea","institution":"Swansea University","dsl":"Department of Computer Science"},{"country":"Saudi Arabia","state":"","city":"Shaqra","institution":"Shaqra University","dsl":"Department of Computer Science"}],"personId":192785},{"affiliations":[{"country":"United Kingdom","state":"","city":"Swansea","institution":"Swansea University","dsl":"Department of Computer Science"}],"personId":192070},{"affiliations":[{"country":"United Kingdom","state":"","city":"Swansea","institution":"Swansea University","dsl":"Department of Computer Science"}],"personId":187599}]},{"id":194080,"typeId":13944,"title":"Depth3DSketch: Freehand Sketching Out of Arm's Reach in Virtual Reality","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719717"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=HoPYoJX06tE"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-3866","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[195268,195267],"eventIds":[],"abstract":"Due to the increasing availability and popularity of virtual reality (VR) systems, 3D sketching applications have also boomed.

Users can select the sketching depth with three interaction methods: using the joystick on a single controller, the intersection from two controllers, or the intersection from the controller ray and the user's gaze. We compared these interaction methods in a user study.

Findings from semi-structured interviews (N=30) suggest that WeChat is used for organizational newcomers’ identity learning, primarily through indirect, passive methods such as observation. Identity work includes sharing mundane work life and achievements and forwarding work-related and profession-related information. A flexibility paradox was identified, indicating that newcomers desire an online presence with coworkers while also wanting to withdraw from the demands of being viewed as a good colleague or expert. Thus, this networked performance stifles individualized expressions of newcomers.

These migrants, self-identified as “TikTok Refugees,” engage directly with Chinese natives, overcoming cross-cultural communication barriers. This platform migration provides a unique opportunity to examine the communication behaviors and strategies employed when users from the Western culture integrate into communities primarily composed of users from the Eastern culture. In this study, we analyze 3,510 RedNote posts (mainly posted from America (47%) and China (39.3%)) to characterize how TikTok migrants blend into the platform. Through open coding, we identified 12 cross-cultural communication strategies manifested in newcomers’ posts. We also discuss the critical role of friendly content quality in facilitating successful interactions and the challenges of maintaining sustainable engagement.

Our findings may inform future design and research on how haptic technologies can be used to enhance emotional well-being and connectedness in LDRs.","authors":[{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"College of Design and Innovation","dsl":"Tongji University"},{"country":"Finland","state":"","city":"Espoo","institution":"School of Art, Design and Architecture","dsl":"Aalto University"}],"personId":191896},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Academy of Arts & Design","dsl":"Tsinghua University"}],"personId":193884}]},{"id":194122,"typeId":13944,"title":"Finger-to-Palm: Single-Handed Touch Gestures Using the Palm","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720213"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=J2fqZ6pqAxA"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-2236","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[195268,195267],"eventIds":[],"abstract":"This paper introduces the Finger-to-Palm touch interaction, a new interface for enhancing head-mounted display interactions.

Therefore, social artifacts like artificial companions are inherently deceptive -- they are designed to give the impression that they are able to do something that they cannot. This deception is a double-edged blade. On one hand, as pandemic restrictions fractured social circles and prevented community gatherings, artificial companions have become social lifelines for many. On the other hand, consumers' attachment to their artificial companions renders them vulnerable to exploitation by the provider of the robot of their affections. How can policymakers enable people to enjoy the benefits of artificial companions while protecting them from exploitation by the corporate entities controlling these robots? To answer this question, I construct a framework for understanding the deception of artificial companions. I propose that there are three steps to the deception of artificial companions: exposure, internalization, and vulnerability. I further argue that, the current tools available to the Federal Trade Commission collapses these three steps under the umbrella of \"deception\", which results in both overinclusive and underinclusive applications of the FTC authority. Instead, to guard against the harms from artificial companions, policymakers need to account for the multi-step nature of artificial companion deception. One avenue of this reform involves a change in how the FTC views artificial companions: artificial companions should be presumed to be harmful, and that presumption should only be rebutted where the provider of the robot is safeguarded against leveraging consumers' attachment against their interests.","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Ottawa","institution":"University of Ottawa","dsl":"Graduate Studies in Law"}],"personId":192827}]},{"id":194134,"typeId":13944,"title":"Interactive Sketchpad: A Multimodal Tutoring System for Collaborative, Visual Problem-Solving","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719790"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=L9cLxcSkXSw"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-3441","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196298,196304],"eventIds":[],"abstract":"\\newcommand{\\name}{\\textsc{Interactive Sketchpad}}\r\n\r\nHumans have long relied on visual aids like sketches and diagrams to support reasoning and problem-solving.

A user study with 35 participants revealed that users experienced stronger positive emotions and higher moral evaluations when their agents' decisions aligned with their goals, while frustration and distrust arose when opposing agents were prioritized. Public contexts encouraged compromise, as consideration for others reduced negative emotions. Fairness violations significantly eroded trust in agents, though users often rationalized these actions when personally benefiting.

We aim to bridge this gap by exploring how CAs can facilitate meaningful social interactions. Through nine scenario-based interviews with older adults living alone, we examined their perceptions of CAs that support relationship-building and mediate meaningful connections, focusing on connecting with others rather than offering companionship. Participants were skeptical yet curious about CAs for socialization. They showed interest in the concepts due to their potential for accessible and personalized socio-emotional connections. However, they also raised significant concerns related to privacy and relational trust. We offer insights into how to better design CAs to meet the socio-emotional needs of older adults.","authors":[{"affiliations":[{"country":"United States","state":"Indiana","city":"Indianapolis","institution":"Indiana University - Indianapolis","dsl":"Luddy School of Informatics, Computing, and Engineering-Indianapolis"}],"personId":192801},{"affiliations":[{"country":"United States","state":"Indiana","city":"Indianapolis","institution":"Indiana University, Indianapolis","dsl":""}],"personId":192265},{"affiliations":[{"country":"United States","state":"Indiana","city":"Indianapolis","institution":"Indiana University Indianapolis","dsl":"DEPARTMENT OF HUMAN-CENTERED COMPUTING"}],"personId":193909},{"affiliations":[{"country":"United States","state":"Indiana","city":"Indianapolis","institution":"Indiana University - Indianapolis","dsl":"Luddy School of Informatics, Computing, and Engineering"}],"personId":193764}]},{"id":194165,"typeId":13944,"title":"\"Hello, Mr Tree\": Toying with Playful Conversational AI in the Early Years","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719878"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=m6Zbx54XtpI"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-5729","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196284,196461],"eventIds":[],"abstract":"The use of generative AI is increasingly integrated into childhood education, primarily with text-to-image generation and older age ranges.

Through ablation studies and visualization, we find that each modality's importance varies from each task, and there are also correlations between tasks.","authors":[{"affiliations":[{"country":"China","state":"Guangxi","city":"Guilin","institution":"Guilin University of Electronic Technology","dsl":"Guangxi Key Laboratory of Trusted Software"}],"personId":193696},{"affiliations":[{"country":"China","state":"","city":"Chengdu, Sichuan Province","institution":"University of Electronic Science and Technology of China","dsl":"School of Computer Science and Engineering"}],"personId":192966},{"affiliations":[{"country":"China","state":"Guangxi","city":"Guilin","institution":"Guilin University of Electronic Technolog","dsl":"Guangxi Key Laboratory of Trusted Software"}],"personId":193892},{"affiliations":[{"country":"China","state":"Guangxi","city":"Nanning","institution":"Guangxi Zhuang Autonomous Region Information Center","dsl":"Guangxi Key Laboratory of Digital Infrastructure"}],"personId":192741}]},{"id":194180,"typeId":13944,"title":"Talk to You More, Listen to You More, and Feel Better in Your Mind: Utilizing Self-talk as a Mechanism of Action for Alleviating Anxiety","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720071"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-3542","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196307,196314],"eventIds":[],"abstract":"While self-talk represents a promising Mechanism of Action (MoA) for anxiety management, the unfamiliarity of hearing one's own voice poses significant challenges for therapeutic engagement. Through two empirical studies (N=60, N=119), we examined a novel digital therapeutic approach combining Acceptance and Commitment Therapy (ACT) with self-talk externalization. Our first study confirmed self-talk's therapeutic potential but highlighted user discomfort with voice experiences. To address this, we developed a systematic voice equalization algorithm using Analytical Hierarchy Process (AHP) to identify optimal voice modifications through progressive refinement of 14 voice types. Our second study implementing this algorithm demonstrated both improved anxiety outcomes and enhanced user engagement. Participants reported that interacting with their modified voice facilitated deeper self-acceptance and emotional understanding. These findings suggest that self-talk, when properly integrated with voice equalization techniques, can effectively support anxiety reduction while promoting sustained therapeutic engagement in digital mental health interventions.","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"HCI Lab"}],"personId":191910},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"HCI Lab"}],"personId":191892},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"HCI Lab"}],"personId":193126},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"HCI Lab"}],"personId":192768},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"HCI Lab"}],"personId":194027},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Yonsei University","dsl":"HCI Lab"}],"personId":193289},{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Sangmyung University","dsl":"Decision Making and Learning Lab, Department of Human-Centered AI"}],"personId":193939}]},{"id":194181,"typeId":13944,"title":"ARTimeTravel: Understanding Spatial Changes in Heritage Sites over Time through a Web-Based Augmented Reality Serious Game","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719904"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=uuksc43a3_k"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-5537","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[195268,195267],"eventIds":[],"abstract":"Heritage sites, as dynamically evolving social spaces, undergo spatial and cultural changes over time that are important for cultural heritage conservation and visitor experience.

To assess UX practitioners' perceptions of AI, we analyzed over 120 articles and discussions from UX-focused subreddits. Our findings indicate that while practitioners express optimism about AI reducing repetitive work and augmenting creativity, they also highlight concerns about over-reliance, cognitive offloading, and the erosion of critical design skills.

Additionally, topic dependency was a key factor, with participants reporting lower trust in AI when addressing societally debated topics (e.g., migration) versus health or entertainment topics. These perceptions were further influenced by interactions among cultural context, content domains, and explainability conditions. The result highlights the importance of integrating cultural and contextual nuances into the design of AI systems, offering actionable insights for the development of culturally adaptive and explainable AI tailored to diverse user needs and expectations across domains.","authors":[{"affiliations":[{"country":"Korea, Republic of","state":"","city":"Seoul","institution":"Seoul National University","dsl":"Human-Computer Interaction+Design Lab"}],"personId":192101},{"affiliations":[{"country":"Germany","state":"","city":"Tübingen","institution":"Leibniz-Institut für Wissensmedie","dsl":""}],"personId":193741},{"affiliations":[{"country":"Germany","state":"","city":"Tübingen","institution":"University of Tübingen","dsl":""}],"personId":191859}]},{"id":194224,"typeId":13944,"title":"Navigating Emotions Through Art: Recommendations for Designing Art-Therapy Based Chatbots for Trauma-Impacted Youth","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719869"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=CsUSdjRopGc"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-3126","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196282,196458],"eventIds":[],"abstract":"In this study, we design and deploy a novel system to examine the safety and efficacy of using a chatbot to conduct aspects of art therapy with youth who have experienced developmental trauma, focusing on supporting emotion identification, processing, and expression.

Using seasonal visualizations as probes during the interviews, we found that blood glucose management is highly individual with the same factors yielding divergent outcomes across participants.

This paper presents Safety Sense, an investigation of two AR warning modality combinations designed to enhance urban cyclists' perceived safety during motorcycle overtaking events: (1) a centralized visual display with warning sounds and (2) a bilateral visual display with voice prompts. Through a real-road study with 20 participants examining motorcycle overtaking events, this research evaluates the effectiveness of these combinations across three key dimensions: risk perception, directional awareness, and warning detection. Results show that both combinations significantly improved perceived safety compared to baseline conditions (p < .001, η² > .69), with the bilateral display and voice prompts outperforming the others in directional awareness and warning detection. Interview findings suggest that visual cues may be more effective than audio in facilitating rapid perception and response in complex urban traffic situations.

We implement this idea in a tool named CompSketch. CompSketch features a freeform canvas that allows designers to sketch and organize multiple disjoint ideas without assuming every stroke contributes to the final design.

To address this, our study aimed to suppress harmful behavioral activation by inducing harmless alternatives. Specifically, we sought to create a VR-based destructive experience using pseudo-loud vocalization that does not require actual voice production, achieved through auditory stimuli and laryngeal vibratory stimuli. Experimental results showed that vibratory stimuli enhanced the loud vocal agency and may have amplified the positive emotional effects of vocalization itself.

Through a VR study (N=18), we evaluated PaveFlow's effectiveness under two AV density conditions (single vs. multiple AVs) and a baseline condition without PaveFlow.

This performance remained consistent across both single and multiple AV conditions, despite persistent tensions in priority negotiation.

Results show how participants identified distinct differences in communication styles—such as mechanical responses, repetitive messaging, and emotional flatness—that shaped their perceptions and suspicions of interacting with automated chatbots rather than authentic humans.","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Toronto","institution":"University of Toronto","dsl":"School of Information"}],"personId":192322},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Human Computer Interaction"}],"personId":193700},{"affiliations":[{"country":"Germany","state":"NRW/Siegen","city":"Siegen","institution":"University of Siegen","dsl":"Human Computer Interaction"}],"personId":192686},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Human Computer Interaction"}],"personId":192951},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"Siegen university","dsl":""}],"personId":191834},{"affiliations":[{"country":"Germany","state":"North Rhine-Westphalia","city":"Siegen","institution":"University of Siegen","dsl":"Human Computer Interaction"}],"personId":192922},{"affiliations":[{"country":"Germany","state":"","city":"Siegen","institution":"University of Siegen","dsl":"Information Systems"}],"personId":192882},{"affiliations":[{"country":"Germany","state":"NRW","city":"Sankt Augustin","institution":"Bonn-Rhein-Sieg University of Applied Science","dsl":"Institute for Consumer Informatics"}],"personId":186059}]},{"id":194334,"typeId":13944,"title":"RhythmBlink: Prompting Eye Blinks in Smart Glasses to Prevent Dry Eye Syndrome","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719954"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=oEWU7MRkSDg"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-5105","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196301,196460],"eventIds":[],"abstract":"Discreet, lightweight, optical see-through smart glasses are an emerging device form factor with high potential for integration into our daily lives.

Existing methods such as visualizing physical performance via video-recording have been used to support the reflection of craft practitioners, but they struggle to capture the subtle bodily actions and perceptions central to craft.

It can record muscle activity and fingertip vibration when the potter touches the clay, which then translates into tactile stimuli for post-action reflection. Comparing findings from two workshops with potters of varying experience levels, we observed that supplementing conventional video-based reflection with our haptic cues helped reveal subtle force patterns and correct misconceptions about both one’s own and others’ actions. These preliminary results suggest a potential for deeper skill understanding during reflection, as well as more nuanced communication in skill-based discussions.","authors":[{"affiliations":[{"country":"Japan","state":"Kanagawa","city":"Yokohama","institution":"Gradute School of Media Design","dsl":"Keio University"}],"personId":192773},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":182681},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":186820},{"affiliations":[{"country":"Japan","state":"","city":"Nagoya","institution":"Nagoya Institute of Technology","dsl":"Electrical and Mechanical Engineering"}],"personId":183207},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":187638}]},{"id":194364,"typeId":13944,"title":"Prompting Generative AI with Interaction-Augmented Instructions","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720080"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=KIDIIDYtdmY"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-2287","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196308,196315],"eventIds":[],"abstract":"The emergence of generative AI (GenAI) models, including large language models and text-to-image models, has significantly advanced the synergy between humans and AI with not only their outstanding capability but more importantly, the intuitive communication method with text prompts.

To address the issue, researchers have explored augmenting text-based instructions with interactions that facilitate precise and effective human intent expression, such as direct manipulation. However, the design strategy of interaction-augmented instructions lacks systematic investigation, hindering our understanding and application. To provide a panorama of interaction-augmented instructions, we propose a framework to analyze related tools from why, when, who, what, and how interactions are applied to augment text-based instructions. Notably, we identify four purposes for applying interactions, including restricting, expanding, organizing, and refining text instructions. The design paradigms for each purpose are also summarized to benefit future researchers and practitioners.","authors":[{"affiliations":[{"country":"China","state":"","city":"Hong Kong","institution":"The Hong Kong University of Science and Technology","dsl":"Department of Computer Science and Engineering"}],"personId":185781},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Microsoft Research Asia","dsl":""}],"personId":184851},{"affiliations":[{"country":"United States","state":"Illinois","city":"Evanston","institution":"Northwestern University","dsl":"Kellogg School of Management"}],"personId":192140},{"affiliations":[{"country":"China","state":"","city":"Beijing","institution":"Microsoft Research Asia","dsl":""}],"personId":193152},{"affiliations":[{"country":"China","state":"","city":"Hong Kong","institution":"The Hong Kong University of Science and Technology","dsl":"Department of Computer Science and Engineering"}],"personId":187993}]},{"id":194365,"typeId":13944,"durationOverride":120,"title":"Towards a Domain Expert Evaluation Framework for Conversational Search in Healthcare","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719675"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=d_DBBzvPPWo"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-3014","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196289],"eventIds":[],"abstract":"The rise of large language models for client-facing conversational search in healthcare necessitates evaluation frameworks that enable the assessment and comparison of these tools.

For instance, when a cute kitten appears in a video alongside a \"scratching\" action and pain, the kitten's action is perceived as the cause of the pain, transforming the experience into a pleasant interaction. To evaluate the effectiveness of this approach, the study examined whether the interpretation of pain stimulation, the level of discomfort, and the pain tolerance threshold were affected when electrical stimulation from the side of a smartphone was used as a source of pain and a cat scratching animation was displayed on the screen under varying conditions. The results indicated that participants with a higher tolerance for electrical stimulation experienced an increase in their tolerance for discomfort when the visual and sensory stimuli were presented together. Additionally, participants were more likely to attribute the stimulation to the cat's action. However, no significant differences were observed in responses to pain-related questions. These findings suggest that while this method may not reduce the intensity of pain, it could lower the discomfort associated with it.","authors":[{"affiliations":[{"country":"Japan","state":"","city":"Tokyo ","institution":"The University of Electro-Communications","dsl":"Graduate School of Informatics and Engineering"}],"personId":193284},{"affiliations":[{"country":"Japan","state":"Tokyo","city":"Chofu","institution":"The University of Electro-Communications","dsl":""}],"personId":192147},{"affiliations":[{"country":"Japan","state":"Tokyo","city":"Chofu","institution":"The University of Electro-Communications","dsl":"Department of Informatics"}],"personId":192536},{"affiliations":[{"country":"Japan","state":"Tokyo","city":"Chofu","institution":"The University of Electro-Communications","dsl":""}],"personId":192459},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"The University of Electro-Communications","dsl":"Graduate School of Informatics and Engineering"}],"personId":192834},{"affiliations":[{"country":"Japan","state":"","city":"Chofu","institution":"The University of Electro-Communication","dsl":""}],"personId":193674}]},{"id":194370,"typeId":13944,"durationOverride":120,"title":"Rethinking Heuristics, Are We Heading the Right Way?

In addition, this study reveals the potential of combining LLMs and VR-based data visualization to provide personalized feedback for users.","authors":[{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei ","institution":"National Taipei University of Technology","dsl":""}],"personId":192112},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei","institution":"National Taipei University of Technology","dsl":"XR Lab"}],"personId":192067},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei","institution":"National Taipei University of Technology","dsl":""}],"personId":193772},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei City","institution":"National Taipei University of Education","dsl":"Department of Mathematics and Information Education"}],"personId":192878},{"affiliations":[{"country":"Taiwan","state":"","city":"Taipei","institution":"National Taipei University of Technology","dsl":"Department of Interaction Design"}],"personId":193495}]},{"id":194378,"typeId":13944,"title":"BioForms: Exploring the Materiality and Interactive Affordances of Algae-based Bioplastics","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719990"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=zX3XKIMtbIs"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-4110","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196297,196303],"eventIds":[],"abstract":"For a long time, the primary focus of bioplastics has been to replace petroleum-derived plastics. As a result, current fabrication processes rarely adapt to the inherent characteristics of bioplastics, failing to showcase their true capabilities. This paper offers a series of unique properties of algae-based bioplastics uncovered through the Material-Driven Design framework, and fabrication processes that reveal novel affordances. We leverage properties often considered limitations such as shrinkage, heat and moisture reactivity, swelling, and long drying times to develop four fabrication techniques: agar screenprinting, laser cut reactive patterning, spongy foam structure, and 2.5D poured membranes. By utilizing commercially available ingredients and accessible tools, we aim to lower the barrier to exploring biomaterials in DIY settings. We advocate for understanding a material’s inherent characteristics as a first step in research and development, moving the focus beyond a human-centered to a material-led approach, further inspiring novel and better-suited applications.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"University of California, Berkeley","dsl":"Jacobs Institute for Design Innovation"}],"personId":192697},{"affiliations":[{"country":"United States","state":"California","city":"Berkeley","institution":"University of California, Berkeley","dsl":"Jacobs Institute for Design Innovation"}],"personId":192513}]},{"id":194379,"typeId":13944,"durationOverride":120,"title":"On Error Classification from Physiological Signals within Airborne Environment","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719995"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=e-u6NPrFHSQ"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-6777","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196289],"eventIds":[],"abstract":"Human error remains a critical concern in aviation safety, contributing to 70-80% of accidents despite technological advancements.

Participants completed standardized multi-tasking scenarios across conditions ranging from laboratory settings to straight-and-level flight and 2G manoeuvres while we collected synchronized physiological data. Our findings demonstrate that EEG-based classification maintains high accuracy (87.83%) during complex flight manoeuvres, comparable to laboratory performance (89.23%). Eye-tracking showed moderate performance (82.50%), while ECG performed near chance level (51.50%). Classification accuracy remained stable across flight conditions, with minimal degradation during 2G manoeuvres.

By combining qualitative content analysis with a graph representation of Social Media Journeys, we present how social media migration processes are motivated by the interplay of environmental and platform factors. We find that peer-driven popularity, the timing of feature adoption, and personal perceptions of migration causes --- such as security --- shape individuals’ reasoning for migrating between social media platforms. With this work, we aim to pave the way for future social media platforms that foster meaningful and enriching online experiences for users.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Bochum","institution":"Center for Advanced Internet Studies","dsl":""}],"personId":193737},{"affiliations":[{"country":"Germany","state":"","city":"Bochum","institution":"Center for Advanced Internet Studies (CAIS)","dsl":""},{"country":"Germany","state":"","city":"Wuppertal","institution":"University of Wuppertal","dsl":""}],"personId":184442}]},{"id":194393,"typeId":13953,"title":"Identity Boards: Exploring Use of Mixed Media Expression in Online Queer Spaces","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720307"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25n-9942","source":"PCS","trackId":13440,"tags":[],"keywords":[],"sessionIds":[194984,191331],"eventIds":[],"abstract":"Our project \"Identity Boards'' on Discord, is an extension tool to promote healthy communication within LGBTQIA+ communities, that aim to reduce microaggressions and foster a more inclusive online environment. \"Identity Boards\" enable users to visually express their experiences and identities through customized media collections, creating a space for self-expression and understanding.

WETform introduces four distinct modalities—Pattern, Texture, Actuation, and Mist—each highlighting specific material properties and interaction affordances of shape-changing water surfaces. These modalities enable applications such as creating animated water pixel patterns, augmenting visual content with dynamic textures, manipulating objects on water surfaces, and engaging multiple senses, including scent, through the mist. \r\n\r\nBy integrating water’s fluid, ephemeral, and multi-sensory qualities into an interactive system, WETform expands the design space of computational materials, offering new possibilities for dynamic, material-based interfaces in HCI.

This helps prevent students from falling into a vicious cycle of decreased academic achievement and increased aversion to learning, potentially leading to dropout. Data-driven models often outperform eXplainable Artificial Intelligence (XAI) models in predicting learning outcomes, yet their lack of interpretability can hinder trust from educators. Therefore, this study developed an XAI information fusion framework that not only extracts potential trends from the time series of student grades to enhance predictive performance but also mines explicit relationships between classroom behaviors and learning outcomes. This reveals the behavioral causes behind changes in grades.

These findings highlight the complex role of AI literacy in promoting critical engagement and the importance of education to deepen users’ technological understanding.","authors":[{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"Loyola University Chicago","dsl":""}],"personId":191987},{"affiliations":[{"country":"Singapore","state":"","city":"Singapore","institution":"National University of Singapore","dsl":"Division of Industrial Design"}],"personId":185769}]},{"id":194463,"typeId":13944,"title":"PhysioBots: Engaging K-12 Students with Physiological Computing and Robotics","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720106"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=YF7ZmlkLnV4"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-9957","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196284,196461],"eventIds":[],"abstract":"Dr. Chris S.

Our detailed measurements revealed that tactile acuity decreases linearly from the tip to the pad and drops steeply at the sides. Using these findings, we optimized electrodes for an electro-tactile device by extending the sensory range from the DIP joint to the fingertip, narrowing electrode spacing toward the tip, and increasing spacing on the sides compared to the finger pad. This optimization enables a wider and higher-density tactile presentation compared to the conventional one and is expected to increase the speed and accuracy of recognition and manipulation tasks using tactile sensation by increasing the amount of information transmitted.

However, traditional coaching feedback struggles to provide assistance on instructing the time to swing and the amount of power required to return the ball, especially during the user's swing motion. To tackle such a challenge, we present ModPaddle, a racket-shaped force feedback system that can modify the user's swing power and provide real time assistance. ModPaddle utilizes the gyroscopic effect to generate a force that can either assist or limit the user's swing power and provide the swing timing. The proposed system can generate gyroscopic force up to 7.56 N, enabling the user to successfully return the ball to proper range of distance on the opponent's field. ModPaddle aims to revolutionize table tennis training by providing instant, tangible guidance potentially teaching players the correct amount of power and swing timing to return the ball to desired distance.","authors":[{"affiliations":[{"country":"Japan","state":"Saitama","city":"Fujimino-shi","institution":"KDDI Research, Inc.","dsl":""}],"personId":193374},{"affiliations":[{"country":"Japan","state":"Saitama","city":"Fujimino-shi","institution":"KDDI Research, Inc.","dsl":""}],"personId":193661},{"affiliations":[{"country":"Japan","state":"Saitama","city":"Fujimino-shi","institution":"KDDI Research, Inc.","dsl":""}],"personId":193630}]},{"id":194533,"typeId":13944,"title":"Yurt Portal: A Nomadic Spatial Media with Real-Time Cross-Cultural Mirroring for Embodied Digital Tourism","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719740"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=Q4DkYeVr1g4"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-8445","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[195268,195267],"eventIds":[],"abstract":"Digital tourism describes the activity of leveraging interactive media to engage in an immersive cultural encounter, which allows people to explore diverse cultures without physical restrictions.

While visual elements have traditionally dominated spatial design, the impact of tactile sensations as flooring materials on perception remains largely overlooked. This study examines how soft carpet and hard tile floors influence subjective evaluations of objects. Using abstract shapes inspired by the Bouba and Kiki phenomenon, 86 participants (44 on soft, 42 on hard flooring) evaluated two objects based on twenty-eight adjective pairs related to sight and touch within a controlled environment. Results showed that soft carpet floors enhanced perceptions of sophistication and beauty in Kiki, while hard tile floors amplified Bouba’s elasticity and brightness. These findings highlight a “figure-ground relationship,” where flooring texture interacts with sensory information to shape object perception. By focusing on the physical-material aspects of Human-Building Interaction (HBI), this research underscores the role of material effects in spatial design. It offers insights into how flooring can subtly guide cognition, behavior, and aesthetic experiences in architectural spaces.","authors":[{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University","dsl":"Keio University Graduate School of Media Design"}],"personId":192428},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":192894},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":192701},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":186820},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University","dsl":"Keio University Graduate School of Media Design"}],"personId":193823},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"Nomura LTD.","dsl":""}],"personId":192638},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"NOMURA Co.,Ltd.","dsl":""}],"personId":193482},{"affiliations":[{"country":"Japan","state":"","city":"Tokyo","institution":"Nomura LTD.","dsl":""}],"personId":193618},{"affiliations":[{"country":"Japan","state":"Tokyo","city":"Minato-ku Daiba","institution":"NOMURA Co.,Ltd.","dsl":""}],"personId":193862},{"affiliations":[{"country":"Japan","state":"","city":"Yokohama","institution":"Keio University Graduate School of Media Design","dsl":""}],"personId":187638}]},{"id":194538,"typeId":13944,"title":"Generative AI for medical education: Insights from a case study with medical students and an AI tutor for clinical reasoning","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3721208"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=S-QhlLAoBXs"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-1949","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196284,196461],"eventIds":[],"abstract":"Generative Artificial Intelligence (AI), particularly Large Language Models (LLMs), have demonstrated significant potential in clinical reasoning skills such as history-taking and differential diagnosis generation—critical aspects of medical education.

This enables flexible manual interactions, and supports ergonomic interactions.","authors":[{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":182918},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":182877},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":185022},{"affiliations":[{"country":"United States","state":"Illinois","city":"Chicago","institution":"University of Chicago","dsl":""}],"personId":183578}]},{"id":194546,"typeId":13944,"title":"Reframing Automation Benefits: A Human-Centered Approach to Expanding the Value of AI-Generated Reports in Healthcare","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719979"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=6K47z9mUZI4"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-8695","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196307,196314],"eventIds":[],"abstract":"The use of Large Language Models (LLMs) for generating medical reports is being increasingly explored across medical specialties.

It builds on the earlier XRAYHEAD, which produced the illusion of seeing and touching a skeleton inside the head. The essential mechanism of XRAYHEAD is to create a visual image where a skeleton appears to be embedded inside the mirrored reflection of the head by appropriately combining the reflected and transmitted images with a half-mirror at an optimal light intensity. The primary innovation of the new system lies in opening the skull along the forehead line and incorporating a compact sound instrument with a light sensor. This system modifies the sound's timbre based on hand penetration depth, enhancing the illusion of sound emanating from inside the head. To evaluate its effectiveness, we conducted two experiments. In the first, 86% of participants reported experiencing an illusory sensation of skull intrusion and a lingering object inside the head. The second experiment showed that audio-tactile integration significantly strengthened the sensation of sound originating from one's head (magnet-head illusion).","authors":[{"affiliations":[{"country":"Japan","state":"","city":"Nagoya","institution":"Nagoya City University","dsl":""}],"personId":192215},{"affiliations":[{"country":"Japan","state":"Aichi","city":"Nagoya","institution":"Nagoya City University","dsl":"Graduate School of Design and Architecture"}],"personId":193336}]},{"id":194561,"typeId":13944,"durationOverride":120,"title":"Transitioning Focus: Viewing Human-AI Collaboration as Mixed-focus Collaboration","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720109"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=xdrrINIrTEc"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-9991","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196290],"eventIds":[],"abstract":"The abilities that recent AI models presented, like multi-modal content generation and reasoning, allow us to see the possibility of human-AI collaboration.

The accuracy and speed of such goal-directed movements depend on their estimated energy and time costs. In VR, vision is stimulated separately from tactile and kinesthetic sensory modalities. For instance, a virtual pointing device can be visually presented as heavy while being physically lightweight. Yet, it is unknown how visual and physical weight cues contribute to our strategy to optimize movements in terms of accuracy and speed. In a study with 32 participants, we found physical weight (additional weight of the controller) increases precision and movement time when pointing in VR. Interestingly, we found that visually conveyed weight (additional volume at the controller's 3d model) also increases movement time, suggesting that adjusting the appearance of virtually held objects can affect the performance of pointing movements. We interpret our findings in light of motor-cognitive models and discuss implications for VR designers.","authors":[{"affiliations":[{"country":"Germany","state":"","city":"Berlin","institution":"Berlin University of Applied Sciences and Technology","dsl":""}],"personId":192752},{"affiliations":[{"country":"Germany","state":"","city":"Regensburg","institution":"University of Regensburg","dsl":""}],"personId":192087},{"affiliations":[{"country":"Germany","state":"","city":"Regensburg","institution":"University of Regensburg","dsl":""}],"personId":193835},{"affiliations":[{"country":"Germany","state":"","city":"Regensburg","institution":"University of Regensburg","dsl":""}],"personId":192054},{"affiliations":[{"country":"Germany","state":"","city":"Berlin","institution":"Beuth University of Applied Sciences","dsl":""}],"personId":192029},{"affiliations":[{"country":"Germany","state":"","city":"Regensburg","institution":"University of Regensburg","dsl":""}],"personId":185855},{"affiliations":[{"country":"Germany","state":"","city":"Regensburg","institution":"University of Regensburg","dsl":"Media informatics group"}],"personId":187644}]},{"id":194587,"typeId":13944,"durationOverride":120,"title":"\"It Warned Me Just at the Right Moment\": Exploring LLM-based Real-time Detection of Phone Scams","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720263"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=fWCI8JwMCKg"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-9873","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196290],"eventIds":[],"abstract":"Despite living in the era of the internet, phone-based scams remain one of the most prevalent forms of scams. \r\nThese scams aim to exploit victims for financial gain, causing both monetary losses and psychological distress. \r\nWhile governments, industries, and academia have actively introduced various countermeasures, scammers also continue to evolve their tactics, making phone scams a persistent threat.\r\nTo combat these increasingly sophisticated scams, detection technologies must also advance. \r\nIn this work, we propose a framework for modeling scam calls and introduce an LLM-based real-time detection approach, which assesses fraudulent intent in conversations, further providing immediate warnings to users to mitigate harm.\r\nThrough experiments, we evaluate the method's performance and analyze key factors influencing its effectiveness. \r\nThis analysis enables us to refine the method to improve precision while exploring the trade-off between recall and timeliness, paving the way for future directions in this critical area of research.","authors":[{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"The Hong Kong Polytechnic University","dsl":""}],"personId":192011},{"affiliations":[{"country":"China","state":"","city":"Shenzhen","institution":"Shenzhen University","dsl":""}],"personId":191960},{"affiliations":[{"country":"China","state":"","city":"Hong Kong","institution":"The Hong Kong Polytechinic University","dsl":"Department of Computing"}],"personId":192579},{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"The Hong Kong Polytechnic University","dsl":"Dept. of Computing"}],"personId":191828},{"affiliations":[{"country":"Hong Kong","state":"","city":"Hong Kong","institution":"The Hong Kong Polytechnic University","dsl":"Dept. of Computing"}],"personId":192870},{"affiliations":[{"country":"China","state":"","city":"Hong Kong","institution":"The Education University of Hong Kong","dsl":"Centre for Learning, Teaching and Technology "}],"personId":193690}]},{"id":194588,"typeId":13944,"title":"Combining AI and Crowdsourcing to Identify Misinformation in Online News","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720007"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=NrX6ls3cnXk"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-9510","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196308,196315],"eventIds":[],"abstract":"Misinformation in online news presents a critical challenge as it can influence individuals’ assessment of news articles and impact decision-making.

We discuss the importance of robust funding mechanisms to support all phases of community-based projects and advocate for stronger academic-community partnerships to ensure real-world impact in addressing societal challenges.","authors":[{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"School of Public Health Sciences"}],"personId":186114},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"Games Institute"}],"personId":192199},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Kitchener","institution":"Marillac Place","dsl":""}],"personId":191843},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"School of Public Health Sciences"}],"personId":182746},{"affiliations":[{"country":"Canada","state":"Ontario","city":"Waterloo","institution":"University of Waterloo","dsl":"Stratford School of Interaction Design and Business"}],"personId":183271}]},{"id":194602,"typeId":13944,"title":"Introducing 3D Sketching to Overcome Challenges of View-Consistency and Progressive Development in 2D Generative AI-Based Car Exterior Design","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719731"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=hd-q3onyI0M"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-8550","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196281,196456],"eventIds":[],"abstract":"Recent advances in 2D generative AI are beginning to find applications in highly specialized fields, such as car exterior design.

These findings highlight the importance of the dynamics in conversations within OCCs and provide actionable insights for designing digital environments that foster constructive feedback exchanges.","authors":[{"affiliations":[{"country":"United States","state":"New York","city":"ITHACA","institution":"Information Science","dsl":"Cornell University"}],"personId":193998},{"affiliations":[{"country":"United States","state":"New York","city":"ITHACA","institution":"Information Science","dsl":"Cornell University"}],"personId":192860}]},{"id":194616,"typeId":13944,"durationOverride":120,"title":"Discrepancies in Mobile App Permissions: Exploring Transparency and User Awareness in the Android Ecosystem","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719902"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=RidIhTyDv3g"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-7468","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196292],"eventIds":[],"abstract":"Transparency in mobile app permissions is essential for maintaining user trust and protecting privacy as individuals increasingly rely on digital solutions.

Our qualitative findings reveal that while adolescents value privacy, emotional support, and localized content in mental health tools, existing chatbots lack personalization and cultural relevance. These findings inform recommendations for culturally sensitive chatbot design that prioritizes anonymity, tailored support, and localized resources to better meet the needs of adolescents in India. This work advances culturally sensitive chatbot design by centering underrepresented populations, addressing critical gaps in accessibility and support for adolescents in India.\r\n","authors":[{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"University of Pennsylvania","dsl":""}],"personId":192068},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"University of Pennsylvania","dsl":"Department of Computer and Information Science"}],"personId":193588},{"affiliations":[{"country":"India","state":"Telangana","city":"Hyderabad ","institution":"Mamata Academy of Medical Sciences","dsl":"School "}],"personId":192867},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"University of Pennsylvania","dsl":"Department of Computer and Information Science"}],"personId":185045},{"affiliations":[{"country":"United States","state":"Pennsylvania","city":"Philadelphia","institution":"University of Pennsylvania","dsl":"Computer and Information Science"}],"personId":193409}]},{"id":194630,"typeId":13944,"title":"KnuckleBoard: Knuckle-based Input in Augmented Reality while Sitting, Standing, and Walking","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3720281"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=Bctnc_sA6NY"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-1618","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[195268,195267],"eventIds":[],"abstract":"Interaction with digital content has changed substantially with the introduction of Augmented Reality (AR).

To explore this idea, we conducted a controlled experiment (N=18) comparing it to the state-of-the-art controller-based input while sitting, standing, and walking. We found that the knuckle method provided a better user experience and was preferred for walking due to its engaging nature and reduced visual focus.

ChatGPT users compared to Google users were faster and more likely to find the correct answers.

The lengthy training cycle, repetitive practice, and frequent mistakes discourage learners, while traditional master-apprentice methods lack adaptability. Meanwhile, societal prejudice and economic uncertainty reduce the allure of ICH careers. To address these issues, we propose intelligent learning strategies that improve accessibility, personalize skill development, and offer better career prospects. Our findings provide empirical evidence for the HCI community and underscore the necessity of more inclusive, sustainable vocational education frameworks for ICH.","authors":[{"affiliations":[{"country":"China","state":"","city":"Shang hai","institution":"Tongji University","dsl":""}],"personId":192630},{"affiliations":[{"country":"China","state":"","city":"Hangzhou","institution":"china academy of art","dsl":""}],"personId":192892},{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"Tongji College of Design and Innovation","dsl":"Intelligent Big Data Visualization Lab"}],"personId":193612},{"affiliations":[{"country":"China","state":"","city":"Shanghai","institution":"Tongji University","dsl":"College of Design and Innovation, Intelligent Big Data Visualization Lab"}],"personId":192163}]},{"id":194700,"typeId":13954,"durationOverride":90,"title":"Factually: A Live, Wearable Fact-Checker","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3721346"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25t-8847","source":"PCS","trackId":13438,"tags":[],"keywords":[],"sessionIds":[194986],"eventIds":[],"abstract":"We present Factually, a novel concept of a live, wearable, fact-checking system that extends users’ ability to discern truth in real time.

We developed a two-agent system: a therapist agent providing problem-solving therapy, and a communication style modifier agent that adjusts these responses according to six communication styles: Authoritative, Concise, Conversationally Dominant, Informal, Sentimental, and Talkative style. An experimental study demonstrated that our system successfully produced perceivable differences in communication styles, with adapted responses receiving significantly higher style-specific ratings compared to unadapted responses. These results suggest that LLM-based therapeutic chatbots can be effectively modified to exhibit distinct communication styles, laying the groundwork for developing culturally adaptive therapeutic chatbots.","authors":[{"affiliations":[{"country":"United States","state":"Washington","city":"SEATTLE","institution":"University of Washington","dsl":"Foster School of Business"}],"personId":192546},{"affiliations":[{"country":"United States","state":"Washington","city":"Seattle","institution":"University of Washington","dsl":"Information Systems and Operations Management, Michael G.

Additionally, we present case studies demonstrating how the augmented dataset and models can support research on human cognition and visualization design, enabling designers to refine visualizations for optimal complexity.\r\nAll supplemental materials are available at \\url{https://osf.io/k4uta}","authors":[{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":"Interactive Computing"}],"personId":193524},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Institute of Technology","dsl":"College of Computing"}],"personId":191966},{"affiliations":[{"country":"United States","state":"Illinois","city":"Evanston","institution":"Northwestern University","dsl":""}],"personId":193716},{"affiliations":[{"country":"United States","state":"Massachusetts","city":"Amherst","institution":"University of Massachusetts, Amherst ","dsl":""}],"personId":193133},{"affiliations":[{"country":"United States","state":"Georgia","city":"Atlanta","institution":"Georgia Tech","dsl":"Interactive Computing"}],"personId":183421}]},{"id":194729,"typeId":13944,"title":"Mapping the Tool Landscape for Stakeholder Involvement in Participatory AI: Strengths, Gaps, and Future Directions","addons":{"doi":{"type":"doiLink","url":"https://dl.acm.org/doi/10.1145/3706599.3719726"},"Presentation Video":{"title":"Presentation Video","type":"video","url":"https://www.youtube.com/watch?v=5hNVXIr0n6Y"}},"recognitionIds":[],"isBreak":false,"importedId":"chi25g-8048","source":"PCS","trackId":13439,"tags":[],"keywords":[],"sessionIds":[196305,196312],"eventIds":[],"abstract":"Stakeholder Involvement (SHI) during technology development is increasingly promoted in responsible AI (rAI) guidance.

This approach has led to a significant gap in understanding the long-term application of these techniques in real-life contexts, which is essential for designing effective ER training games. To address this gap, we developed a biofeedback game incorporating four distinct breathing techniques and conducted a 10-week longitudinal study with 25 participants. After one week of training, the majority of participants demonstrated successful transfer of breathing techniques to real-life scenarios. Our findings provide actionable design insights for promoting long-term skill transfer and highlight the potential of respiratory biofeedback games as sustainable tools for emotion regulation training.

Specifically, it investigates (a) whether individuals exhibit consistent belief reasoning abilities and (b) whether these abilities can be inferred from their nesting capabilities within the JP model framework. To address these questions, we propose a novel processing algorithm inspired by Item Response Theory to estimate reasoning abilities based on participants' responses to diverse reasoning scenarios. A pilot experiment was conducted to validate the methodology and refine the experimental design for future studies. While the small sample size limits the statistical significance of the findings, preliminary results suggest the JP model's potential to capture human higher-order beliefs.

In this talk, we will delve into a series of innovations in the augmented world, augmented interaction, and augmented communication, that aim to facilitate creators, scale XR+AI technology, and help people to better communicate in their physical life.\n\nThe talk starts with Android XR's vision video, followed by pioneering mirrored world system, Geollery. With Depth Lab, Ad hoc UI, Artificial Object Intelligence, and Finger Switches, we present real-time 3D interactions with depth maps, objects, and micro-gestures in XR. To scale such technologies, we built Visual Blocks and InstructPipe, that empower novice users to unleash their inner creativity, by rapidly building machine learning pipelines with visual programming and generative AI. Finally, with CollaboVR, GazeChat, Visual Captions, ThingShare, and ChatDirector, we enrich real-world communication with mid-air sketches, gaze-aware 3D photos, LLM-informed visuals, object-focused views, and co-presented avatars.\n\nWe conclude the talk with highlights of Project Astra, offering a visionary glimpse into the future of a universally accessible metaverse.","authors":[{"affiliations":[{"country":"United States","state":"California","city":"San Francisco","institution":"Google","dsl":""}],"personId":183884}]},{"id":196429,"typeId":13955,"title":"H2L (Champion Sponsor): BodySharing as an Experience-Sharing Interface for Humanity: Shaping a New Form of Empathy","addons":{"Recruitment Info":{"name":"Recruitment Info","title":"Recruitment Information","type":"custom","url":"https://h2l.jp/recruit/"}},"recognitionIds":[],"isBreak":false,"importedId":"17675","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[196438],"eventIds":[],"authors":[]},{"id":196430,"typeId":13955,"title":"Toyota Research Institute (Champion Sponsor): Human Centered AI Research at Toyota Research Institute","recognitionIds":[],"isBreak":false,"importedId":"17676","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[196436],"eventIds":[],"authors":[]},{"id":196431,"typeId":13955,"title":"Fairy Devices (Champion Sponsor): What Is THINKLET?

Drawing from her organization’s work advocating for ethical and inclusive AI on international platforms, Nkonde challenges dominant narratives in tech by centering social impact over technological innovation. She argues that when we begin with the question, \"Who is affected, and how?\", rather than \"What can this technology do?\", we open up possibilities for more just and human-centered AI systems.\nNkonde further unpacks how marginalized perspectives—particularly those informed by Black feminist and queer thought—offer critical tools for identifying and addressing bias, surveillance, and discrimination embedded in algorithmic systems. By examining real-world policy efforts and advocacy strategies, she invites participants to reflect on the ways bias can be actively countered through inclusive design practices, equitable data governance, and values-driven development processes.\nThis keynote calls on designers, educators, and researchers to consider how they might incorporate these critical perspectives into their own product teams, classrooms, and labs—not only to mitigate harm, but to reimagine AI as a tool for collective liberation.","authors":[{"affiliations":[],"personId":196727}]},{"id":196446,"typeId":13943,"durationOverride":5,"title":"Award announcement","recognitionIds":[],"isBreak":false,"importedId":"17692","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[191563],"eventIds":[],"authors":[]},{"id":196447,"typeId":14139,"title":"Closing keynote — Designing Beyond Age: Rethinking Inclusion and Interaction in a 100-Year Life","recognitionIds":[],"isBreak":false,"importedId":"17693","source":"SYS","trackId":13408,"tags":[],"keywords":[],"sessionIds":[191563],"eventIds":[],"abstract":"As societies shift toward unprecedented longevity, HCI faces a compelling challenge and opportunity: How do we design technologies that not only accommodate—but empower—users across all stages of life?\nIn this keynote, Masako Wakamiya shares her lived experience as a late-blooming technologist, digital artist, and active community contributor. Through her journey—from learning computing in her 60s to developing an app for older adults in her 80s—she invites HCI professionals to reconsider assumptions about aging, usability, and agency. Wakamiya reminds us that while aging may bring changes in cognitive and physical abilities, it also deepens emotional insight, strengthens interpersonal connections, and enriches one’s capacity to contribute meaningfully. She challenges the field to move beyond accessibility toward true participation, where older users are not just end-users but co-creators and storytellers. Her insights underscore the need for age-inclusive design practices that not only adapt to changing needs but also celebrate what endures and grows with age—curiosity, creativity, empathy, and community.

Like all AI-powered tools, these code completion tools are not always accurate and can introduce bugs or even security vulnerabilities into code if not properly detected and corrected by a human programmer. One technique that has been proposed and implemented to help programmers locate potential errors is to highlight uncertain tokens. However, little is known about the effectiveness of this technique. Through a mixed-methods study with 30 programmers, we compare three conditions: providing the AI system's code completion alone, highlighting tokens with the lowest likelihood of being generated by the underlying generative model, and highlighting tokens with the highest predicted likelihood of being edited by a programmer. We find that highlighting tokens with the highest predicted likelihood of being edited leads to faster task completion and more targeted edits, and is subjectively preferred by study participants. In contrast, highlighting tokens according to their probability of being generated does not provide any benefit over the baseline with no highlighting. We further explore the design space of how to convey uncertainty in AI-powered code completion tools and find that programmers prefer highlights that are granular, informative, interpretable, and not overwhelming. This work contributes to building an understanding of what uncertainty means for generative models and how to convey it effectively.","authors":[{"affiliations":[{"country":"United
