XR Research: Extended Reality, Spatial Interaction & QoE
Research overview
I investigate how immersive and interactive systems can be designed and evaluated to improve experience quality, task performance, and trust.
What I Research (in plain language)
I study how virtual and augmented reality systems can be built so they actually work well for people — not just technically, but in terms of how natural, comfortable, and useful they feel. My lab measures user experience using questionnaires, eye tracking, and physiological sensors, and applies these findings to improve VR/AR for training, healthcare, and everyday use.
Methods toolbox
Eye tracking · Physiological sensing · Behavioral coding · QoE questionnaires · Simulator studies · Statistical analysis · Multimodal fusion
Related outputs: Psychophysiology-tagged work and QoE-tagged work.
Cross-cutting application domains
Safety-critical training · Public-space MR · Digital twins · Health communication · Intelligent agents
Research lines
XR & Spatial Interaction
Why it matters: Spatial interaction quality directly influences usability, social acceptance, and deployment readiness.
Representative outputs
- Towards Socially Acceptable Virtual Reality Interactions in Public Contexts
- A user study on physically active locomotion in social virtual reality
- Perceptibility and Preference of Dynamic Weight Changes in Virtual Reality Through Pseudo-Haptic and Vibrotactile Cues
Representative projects
Quality of Experience (QoE)
Why it matters: QoE data links technical system behavior to perceived quality, trust, and adoption.
Representative outputs
- Impact of Packet Loss and Delay on Presence and User Experience in VR Cloud Gaming
- Dynamic and Responsible Digital Twins for Extended Reality
- A quality of experience approach for cloud gaming in virtual reality
Representative projects
Psychophysiology & Behavioral Measurement
Why it matters: Multimodal measurements help quantify user state beyond self-report alone.
Representative outputs
- Arousal Effects on Evaluation and Perception in Multimedia Quality
- Assessing Social Acceptability in Immersive Environments
- User-centered measurements for immersive interaction quality
Representative projects
Digital Health & Learning
Why it matters: Human-centered XR can improve engagement and measurable outcomes in education and health communication.
Representative outputs
- The digitalization of healthcare for older adults (book editorship)
- Immersive interview training and social interaction studies
- Recent XR teaching-transfer publications
