(Re)Evaluating Virtual Reality Manipulation Techniques for Precise Alignment of Complex 3D Objects

We expanded on previous research and conducted a study comparing AMP-IT and WISDOM during alignment of objects with complex geometry to evaluate the potential influence of geometric complexity on the performance, usability, workload and preference. Our findings indicate that participants had faster completion times and higher trial completion rates with AMP-IT on high-precision alignment tasks, contrary to earlier findings that used simple objects. Yet WISDOM is still preferred and considered more usable, despite increased workload and poorer performance, exposing participants’...

Exploring Real-Time Affective State Detection and Intelligent Adaptive Interventions in Virtual Reality

There is growing consensus in human-computer interaction (HCI) and affective computing that affect — users’ emotional and psychological states — is a critical contextual dimension for truly adaptive XR systems. While traditional context-aware systems primarily adapt to users’ tasks and environmental conditions, affect-aware systems should extend this capability by continuously inferring users’ affective states, reasoning about their causes within a given context, and delivering adaptive responses that help users mitigate unwanted emotions and successfully progress through their tasks. One example...

From Slides to Space: Interactive Scale Navigation for XR Presentations

This project presents our solution to the 2026 IEEE VR 3DUI Contest challange. We developed a scale-based navigation system with spatialized regions to traverse an immersive presentation, replacing traditional slide decks with embodied movement through a 3D virtual environment. To demonstrate this approach, we designed an immersive presentation centered on the exploration of the solar system, where predetermined regions function as presentation slides. The user, acting as the presenter, exhibits content by scaling and moving the VE over the course...

Exploring Bichronous Collaboration in Virtual Environments

Virtual environments (VEs) empower geographically distributed teams to collaborate on a shared project regardless of time. Existing research has separately investigated collaborations within these VEs at the same time (i.e., synchronous) or different times (i.e., asynchronous). In this work, we highlight the often-overlooked concept of bichronous collaboration and define it as the seamless integration of archived information during a real-time collaborative session. We revisit the time-space matrix of computer-supported cooperative work (CSCW) and reclassify the time dimension as a continuum....

EyeST: Eye-Enhanced Immersive Space to Think with Gaze-Driven Recommendations

The advancements in AI have raised intriguing possibilities for personalized experiences. Imagine if AI could anticipate your interests by analyzing your gaze patterns from the last hour of reading. What if it could recommend insights not just based on the pages you visited but on the specific parts of those pages that held your attention? The concept extends into immersive spaces. In XR, even though you get more space to organize massive amounts of information, you’d still have to exhaustively...

Guided Tours for Asynchronous Collaboration in Virtual Reality

While collaborative virtual environments have been investigated for working in different spaces at the same time, few have investigated the best practices for collaborating in those spaces at different times. We designed a system that allows experts to create engaging tours inside a virtual inspection space, preserving knowledge and insights while requiring observer interaction to follow the tour’s playback. A user study evaluating the influence of these interactions on an observing user’s information recall and user experience indicated that additional...

Welcome to the 3D Interaction Group

The 3D Interaction (3DI) Group performs research on 3D user interfaces (3D UIs) and 3D interaction techniques for a wide range of tasks and applications. Interaction in three dimensions is crucial to highly interactive virtual reality (VR) and augmented reality (AR) applications to education, training, gaming, visualization, and design. We also conduct empirical studies to understand the effects of immersion in VR and AR, the impact of natural and magic 3D interaction techniques, and usability and user experience in 3D UIs.
