There are certain infinite families of square palindromes which are well-known. For example, , ,… ## [TravelGalleria: Supporting Remembrance and Reflection of Travel Experiences through Digital Storytelling in Virtual Reality (CHI ’25 Honourable Mention)](https://www.robertxiao.ca/research/travelgalleria/?utm_source=rss&utm_medium=rss&utm_campaign=travelgalleria) _2025-04-28 · nneonneo · Robert Xiao_ Travel is a powerful yet fleeting experience that can shape personal perspectives and support self-reflection. To recapture the essence of travel, we explored the use of VR as a medium for immersive re-experiencing with an emphasis on storytelling. We developed TravelGalleria, a VR authoring tool that allows users to curate personalized digital galleries. TravelGalleria encourages creative… [Listen](https://robertxiao.ca/pubs/2025_CHI_TravelGalleria.mp4) ## [PatternTrack: Multi-Device Tracking Using Infrared, Structured-Light Projections from Built-in LiDAR (CHI ’25)](https://www.robertxiao.ca/research/patterntrack/?utm_source=rss&utm_medium=rss&utm_campaign=patterntrack) _2025-04-28 · nneonneo · Robert Xiao_ As augmented reality devices (e.g., smartphones and headsets) proliferate in the market, multi-user AR scenarios are set to become more common. Co-located users will want to share coherent and synchronized AR experiences, but this is surprisingly cumbersome with current methods. In response, we developed PatternTrack, a novel tracking approach that repurposes the structured infrared light patterns… [Listen](https://robertxiao.ca/pubs/2025_CHI_PatternTrack.mp4) ## [HaloTouch: Using IR Multi-Path Interference to Support Touch Interactions with General Surfaces (CHI ’25)](https://www.robertxiao.ca/research/halotouch/?utm_source=rss&utm_medium=rss&utm_campaign=halotouch) _2025-04-28 · nneonneo · Robert Xiao_ Sensing touch on arbitrary surfaces has long been a goal of ubiquitous computing, but often requires instrumenting the surface. Depth camera-based systems have emerged as a promising solution for minimizing instrumentation, but at the cost of high touch-down detection error rates, high touch latency, and high minimum hover distance, limiting them to basic tasks. We developed HaloTouch, a… [Listen](https://robertxiao.ca/pubs/2025_CHI_HaloTouch.mp4) ## [How We See Changes How We Feel: Investigating the Effect of Visual Point-of-View on Decision-Making in VR Environments (CSCW ’24)](https://www.robertxiao.ca/research/how-we-see-changes-how-we-feel/?utm_source=rss&utm_medium=rss&utm_campaign=how-we-see-changes-how-we-feel) _2024-11-10 · nneonneo · Robert Xiao_ Virtual reality (VR) can immerse users into engaging experiences, affording opportunities to study behaviour in simulated contexts such as decision-making processes. However, methodological research into designing meaningful VR experiences – experiences that promote appreciation and deeper understanding of a work – is still underdeveloped. In this two-part study, we investigate how visual… [Listen](https://robertxiao.ca/pubs/2024_CSCW_HowWeSeeChangesHowWeFeel.mp4) ## [Press A or Wave: User Expectations for NPC Interactions and Nonverbal Behaviour in Virtual Reality (CHI PLAY ’24)](https://www.robertxiao.ca/research/press-a-or-wave/?utm_source=rss&utm_medium=rss&utm_campaign=press-a-or-wave) _2024-10-15 · nneonneo · Robert Xiao_ Non-Playable Characters (NPCs) are important in games, as they can provide guidance to the player, create social engagement, and advance the game’s narrative. Although much research exists regarding NPC interactions for traditional gaming environments, e.g. desktop or console, fewer works have considered this from a virtual reality (VR) perspective. Our work first uncovers the salient and unique… [Listen](https://robertxiao.ca/pubs/2024_CHIPLAY_PressAOrWave.mp4) ## [VirtualNexus: Enhancing 360-Degree Video AR/VR Collaboration with Environment Cutout and Virtual Replicas (UIST 2024)](https://www.robertxiao.ca/research/virtualnexus/?utm_source=rss&utm_medium=rss&utm_campaign=virtualnexus) _2024-10-14 · nneonneo · Robert Xiao_ Asymmetric AR/VR collaboration systems bring a remote VR user to a local AR user’s physical environment, allowing them to communicate and work within a shared virtual/physical space. Such systems often display the remote environment through 3D reconstructions or 360° videos. While 360° cameras stream an environment in higher quality, they lack spatial information, making them less interactable. We… [Listen](https://robertxiao.ca/pubs/2024_UIST_VirtualNexus.mp4)
