Yang Liu
I am a first-year PhD student at Aarhus University, supervised by Associate Professor Ken Pfeuffer.
I make prototypes of extended reality (XR) interaction techniques and applications, conduct user experiments for evaluation, and write academic papers.
My design of novel interactions is grounded in affordances, metaphors, and human behaviors. For example, a stick-shaped object affords pointing due to its shape. Through our embodied experience with pens and finger dexterity, that object can also support precise drawing and manipulation. By adopting different grip postures, we use the same object for pointing, drawing, or manipulation, as we have learnt and being doing in everyday practice.

News & Updates
I spent an overwhelming week at CHI ‘26, Barcelona. On Wednesday, I presented the paper StylusPort.
I attended the annual retreat of our Human-Centered Computing (HCC) section in the Department of Computer Science. I met new people, talked about science misconduct, and practiced scientific writing.
I spent a productive and meaningful week in the beautiful historical town Lancaster during January 12–16.
Six people of the Aarhus team flew to Lancaster on Monday. On Tuesday, we visited Lancaster University along with our sister lab – GEMINI. On Wednesday and Thursday, the workshop continued at the Lancaster Castle and Storey. Within the three-day workshop, we listened to and presented talks about everyone’s research.
Our work StylusPort: Investigating Teleportation using Stylus in VR has been conditionally accepted by CHI 2026, which will take place in Barcelona, Spain.
I have officially started my PhD study from Jan. 1, 2026. My supervisor is Prof. Ken Pfeuffer, and the PhD topic is Multimodal Spatial Interfaces for Human-AI Collaboration.
I attended ACM UIST ‘25 in Busan, Korea to present my paper. A week later, I went to Daejeon, Korea to attend IEEE ISMAR ‘25. I spent enjoyful time in both places with my friends and colleagues.
Our work At a Glance to Your Fingertips: Enabling Direct Manipulation of Distant Objects Through SightWarp has been accepted by UIST 2025, taking place in Busan, Korea.
