Caught by Surprise, Caught by Culture: Bridging Facial Expression's Recognition and Interpretation of Surprise Across Cultures

Facial expressions are powerful signals of human emotion, shaping both human–human and human–computer interaction. As interactive technologies, from adaptive interfaces to emotion-aware agents, become more pervasive, systems are increasingly expected to recognize and respond to users' emotions naturally. But what if a…

Sustainable Human-AI Collaboration in Creative Contexts: An Integrated Approach of CASA, UTAUT, Psychological Ownership, and Self-Determination Theory

This study examines the psychological mechanisms that enable sustainable human–AI collaboration in creative tasks. Drawing on the CASA paradigm, we frame generative AI as a social collaborator and integrate UTAUT, psychological ownership theory, and self-determination theory to explain users’ continued engagement with…

CHI '26Exploratory Search & Information Seeking +2

Understanding Spatiotemporal-Aware Multimodal Conversational Search in the Outdoor Urban Space

Emerging multimodal conversational search (MCS) tools (e.g., Gemini Live) allow users to search for spatiotemporal information through natural language dialogues as they move through urban space. Despite the growing popularity of these tools, there is limited understanding of how people engage with this technology. To…

Data-Prompt Co-Evolution: Growing Test Sets to Refine LLM Behavior

Large Language Models (LLMs) are increasingly embedded in applications, and people can shape model behavior by editing prompt instructions. Yet encoding subtle, domain-specific policies into prompts is challenging. Although this process often benefits from concrete test cases, test data and prompt instructions are typ…

"Do I Really Need This?": Illuminating Challenges in Integrating Computational Training Tools in Esports Coaching

The rise in popularity and value of esports motivates the creation of computational training tools (CTTs) for learning, assessment, and skill gain. While some tools exist commercially, much of the work in the research literature is rarely used outside of a lab, resulting in a lack of knowledge on the challenges involv…

Seen but Ignored: Understanding User Disengagement from Emergency Alerts in High-Frequency Contexts — A Case Study of South Korea

Public Warning Systems (PWS) are critical infrastructures for protecting lives during emergencies, yet many users increasingly ignore or disable alerts. Prior research has focused on attentive recipients, overlooking those who disengage mentally or behaviorally. We examine disengagement as a gradual process of psychol…

The Timing of Breaks for Resilience: Collective Recovery in Multi-User Virtual Reality

The pursuit of seamlessness in collaborative VR often creates a paradox: concealing technical failures generates asymmetric awareness, fracturing the shared reality essential for teamwork. We argue instead that disruption timing acts as an information structure. Drawing on the theory of rational rituals, we posit that…

DanXeReflect: Interacting with the Spatio-Temporal Past Movements for Embodied, Reflective Choreographic Collaboration

Choreographic reflection relies on iterative dialogue, where dancers and choreographers refine movement through embodied demonstration and shared feedback in studio rehearsal. With the shift to video, this exchange becomes constrained: annotations detach from the body, gestures lose spatial grounding, and subtle varia…

HyPockeTuner: Bringing Hyperparameter Optimization to Mobile Devices

Hyperparameter optimization (HPO) is a long-running process that can span hours or even days. While recent Human-in-the-Loop HPO systems enable monitoring and steering of the process, they are typically designed for desktop environments, which limits their effectiveness in managing prolonged experiments in practice. T…

State Your Intention to Steer Your Attention: An AI Assistant for Intentional Digital Living

When working on digital devices, people often face distractions that can lead to a decline in productivity and efficiency, as well as negative psychological and emotional impacts. To address this challenge, we introduce a novel Artificial Intelligence (AI) assistant that elicits a user's intention, assesses whether on…
