Human-Computer Interaction / Extended Reality

Xuning Hu

I am a first-year PhD student at HKUST, jointly supervised by Prof. Xiaojuan Ma and Prof. Hai-Ning Liang. My research lies at the intersection of Human-Computer Interaction, Extended Reality, and computational modeling. I study how people interact with immersive systems through gaze, hand, and controller input, with the goal of understanding user behavior, developing predictive models, and optimizing interaction techniques.

Research Themes

Understand

Gaze Input

I investigate how people perceive, attend, and act through gaze-centered interaction in immersive environments.

  • Gaze-based steering and target acquisition
  • Eye-tracking accuracy, precision, and robustness
  • Visual attention during XR interaction

Model

Computational Models

I build empirical and computational models that explain how input quality, task dynamics, and environment constraints shape performance.

  • Human performance modeling
  • Data-driven analysis of interaction behavior
  • Predictive models for complex XR tasks

Optimize

Interaction Tasks

I design and evaluate techniques that make selection, steering, typing, and manipulation tasks faster, clearer, and more reliable.

  • Moving target selection
  • Multimodal feedback and input design
  • Task-specific optimization for VR/AR systems
