Research Context

About XR-NPC

Extended Reality Non-Player Characters (XR-NPCs) represent the next generation of intelligent healthcare training systems. The main work involves AI-driven character colleagues running in virtual reality (e.g., Meta Quest headset) built with Unity and Unreal game engines using a cross-platform bridge. These AI-driven characters provide realistic, adaptive, and safe learning environments for medical professionals.

DASEX Framework

D-A-S-E-X (Diagnosis, Adaptation, Safety, Engagement, eXplainability) is a comprehensive evaluation framework specifically designed for AI-driven healthcare simulations, ensuring clinical accuracy, safety, and educational effectiveness.
