Research Vision
- Extended Reality (XR): When does a virtual moment feel real? Studying how presence is formed, broken, and recovered.
- Human-Centered AI: Intelligent systems that read and align with human experience in real time.
- Game Technology: Games as laboratory and muse, powered by real-time 3D and neural rendering.

XR + Interpretive AI
Aligning machine perception with human experience by interpreting user gaze, emotion, and intent inside virtual worlds.

XR + Adaptive AI
Dynamically adjusting virtual environments based on user states to sustain immersion and comfort in real time.

XR + Collaborative AI
Augmenting shared virtual experiences by understanding how users coordinate, recover, and build trust together.

XR + Constructive AI
Constructing coherent, responsive virtual worlds with AI-driven real-time 3D scene representation and neural rendering.
