Recent Research
An Immersive Virtual Reality Learning System with an LLM-Integrated Conversational Avatar for Real-Time Educational Assistance
This project develops an immersive VR learning system integrated with an LLM-powered conversational avatar for real-time educational assistance. The system enables in-environment question answering within a virtual classroom, addressing the lack of open-ended interaction in existing VR tools. A Unity-based prototype with a local LLM was evaluated through case studies and baseline comparison with a PC-based AI system.
Equipment
