Welcome to HCI Tech Lab!

We are a multidisciplinary research group working on physical computing, natural user interface, and socially acceptable interactions. Our research focuses on enabling novel interactions for Extended Reality (XR) through sensing/feedback technology and wearable interface with the aid of applied machine learning while supporting intelligent authoring system.

We envision natural user interactions that overcome physical, mental, and social barriers. To achieve this, we will focus on


  • Embedding Interactive Technologies
  • Advancing Interaction Techniques
  • Authroring User Interface & Experience
