Building a Role-Play Interactive System using LLM for Health Guidance Education

This study develops a “health guidance training system for nursing students” using conversational AI to simulate patient interactions. Health guidance aims to understand health states and change unhealthy behaviors to prevent lifestyle-related diseases, often employing role-playing as a training method. However, traditional role-playing suffers from student's shyness and inexperience. Our solution leverages the ChatVRM system, which integrates speech recognition, natural language generation, speech synthesis, and 3D avatars to create a simulated patient. The system was evaluated by nursing students and faculty through our surveys, with over 70% of participants providing positive feedback on its usefulness, ease of use, and natural interaction. These results suggest the system effectively enhances health guidance training by providing realistic and practical simulations. In future work, we will further improve the system and conduct extensive evaluation experiments.
