Semantic See-through Goggles: Wearing Linguistic Virtual Reality in (Artificial Intelligence)

When language is used as a medium for sensory information—as when one describes a scene in words—a kind of virtual reality emerges: realities projected into the same sentence become virtual/equivalent. We call this Linguistic VR (LVR). LVR is constituted by codes shaped chiefly by majority cultural norms. In today’s w…

TimeMarbles: A More Holistic Approach to Self-Reflecting on Focus in the Knowledge Workplace

Digital tools promoting individual focus are increasingly popular in knowledge work. Yet their narrow framing of attention as a binary of focus versus non-focus can be unsustainable and discourage engagement in other vital activities, such as team coordination and collaboration. We introduce TimeMarbles, a web app tha…

RealTwin: Concept Graph Representation and Grounding Framework for Reality-Preserving Digital Twin Reconstruction

Reconstructing realistic digital twins has become crucial as advances in mixed reality, metaverse, and robotics demand more accurate simulations for the physical world. Despite technical progress, building high-fidelity digital twins from a systematic and human-centered perspective remains underexplored. Drawing from…

Draped Surfaces: A Contour-Adaptive Interface Overlaid on the Physical Environment for Mixed Reality Workspaces

Conventional Mixed Reality (MR) workspaces are frequently organized in cockpit-like layouts, where multiple floating windows surround the user. While this configuration facilitates access to digital content, it often induces occlusion, reducing understanding of the physical environment and limiting access to real-worl…

The AI Genie Phenomenon and Three Types of AI Chatbot Addiction: Escapist Roleplays, Pseudosocial Companions, and Epistemic Rabbit Holes

Recent reports on generative AI chatbot use raise concerns about its addictive potential. An in-depth understanding is imperative to minimize risks, yet AI chatbot addiction remains poorly understood. This study examines how to characterize AI chatbot addiction---why users become addicted, the symptoms commonly report…

AI Twin: Enhancing ESL Speaking Practice through AI Self-Clones of a Better Me

Advances in AI have enabled ESL learners to practice speaking through conversational systems. However, most tools rely on explicit correction, which can interrupt the conversation and undermine confidence. Grounded in second language acquisition and motivational psychology, we present AI Twin, a system that rephrases…

Crystallizing Schemas with Teleoscope: Thematic Curation of Large Text Corpora on Reddit

Large text corpora, such as Reddit posts, have become an increasingly prevalent site of qualitative inquiry. However, most large text corpora are intractable for qualitative researchers. Instead, teams rely on statistical subsampling to reduce corpora to a manageable size for qualitative analysis. While previous work…

LLM-based Embodied Conversational Agent for Reducing Foreign Language Speaking Anxiety in Social VR

Foreign language speaking anxiety (FLSA) poses a major challenge for English-language learners, suppressing confidence and triggering a cycle of avoidance that hinders language acquisition. To address this, we explored the use of LLM-based embodied conversational agents (ECA) in social virtual reality (VR), which prov…

The Words That Can't Be Shared: Exploring the Design of Unsent Messages

People often have things they want to say but hold back in conversations, fearing being vulnerable or facing social consequences. Online, this restraint can take a distinctive form: even when such thoughts are written out - in moments of anger, guilt, or longing - people may choose to withhold them, leaving them unsen…

Advancing Inclusive Digital Well-Being Tools: How Neurodivergent Students Use Distraction Blockers

Neurodivergent students bring diverse cognitive styles and work patterns, and they are often a key audience for digital distraction blockers aimed at managing attention. However, it remains unclear whether these tools are grounded in their lived experiences, raising concerns that tool design may overlook neurodivergen…

Cloning the Self for Mental Well-Being: A Framework for Designing Safe and Therapeutic Self-Clone Chatbots

As digital tools increasingly mediate mental health care, self-clone chatbots can offer a uniquely novel approach to intra-personal exploration and self-derived support. Trained to replicate users’ conversational patterns, self-clones allow users to talk to themselves through their digital replicas. Despite the promis…

Reflective Motion and a Physical Canvas: Exploring Embodied Journaling in Virtual Reality

In traditional journaling practices, authors express and process their thoughts by writing them down. We propose a somaesthetic-inspired alternative that uses the human body, rather than written words, as the medium of expression. We coin this embodied journaling, as people's isolated body movements and spoken words b…

Quantifying Latencies: A Conversation Analysis Approach to Human-Agent Interactions in Virtual Reality

Users feel frustrated when they do not know when to speak with LLM-based agents. Technical delays disrupt the natural rhythm of conversation (turn-taking), yet there is little understanding of how these specific delays impact the back-and-forth flow of interaction. To address this, we analyzed human-agent conversation…

SCORE: A Framework for Quantifying Diegesis in Situated Visualization for Augmented Reality

A central goal of Augmented Reality (AR)-based Situated Visualization (SV) is to seamlessly integrate digital information into its relevant physical context. While existing frameworks describe numerous design dimensions, the field lacks a rigorous model to evaluate this integration. To address this, we introduce SCORE…

"It Seems to Understand My Heart": An Empirical Study of Persona-Driven Persuasive AI Agent for Aging-in-Place in Singapore

Persona-based, empathetic approaches can foster sustainable long-term user-agent engagement in aging-in-place contexts. We present PersonaBot, a persona-driven persuasive agent built on a Dual-Persona framework that constructs user personas and generates culturally diverse, gender- and personality-varied agent persona…

Are You Comfortable Sharing It?: Leveraging Image Obfuscation Techniques to Enhance Sharing Privacy for Blind and Visually Impaired Users

People with Blind Visual Impairments (BVI) face unique challenges when sharing images, as these may accidentally contain sensitive or inappropriate content. In many instances, they are unaware of the potential risks associated with sharing such content, which can compromise their privacy and interpersonal relationship…

Exploring Learners' Expectations and Engagement When Collaborating with Constructively Controversial Peer Agents

Peer agents can supplement real-time collaborative learning in asynchronous online courses. Constructive Controversy (CC) theory suggests that humans deepen their understanding of a topic by confronting and resolving controversies. This study explores whether CC’s benefits apply to LLM-based peer agents, focusing on t…

PASTA: A Scalable Framework for Multi-Policy AI Compliance Evaluation

AI compliance is becoming increasingly critical as AI systems grow more powerful and pervasive. Yet the rapid expansion of AI policies creates substantial burdens for resource-constrained practitioners lacking policy expertise. Existing approaches typically address one policy at a time, making multi-policy compliance…

Leveraging Head Movement for Navigating Off-Screen Content on Large Curved Displays

Large curved displays are ideal for viewing 360° content, such as 3D maps, but typically restrict users to a 180° viewport, leaving information off-screen. Since users naturally direct their heads toward regions on-screen before interacting, head movements offer a promising alternative for workspace manipulation to br…

Roomify: Spatially-Grounded Style Transformation for Immersive Virtual Environments

We present Roomify, a spatially-grounded transformation system that generates themed virtual environments anchored to users' physical rooms while maintaining spatial structure and functional semantics. Current VR approaches face a fundamental trade-off: full immersion sacrifices spatial awareness, while passthrough so…
