The authors propose a new Virtual Reality (VR) system using psychological and physiological data which reflect users’ mental state and voluntary and involuntary reactions. The VR system consists of a psychological and physiological data measurement system, human information processing model units, and an intelligent feedback system. This VR system can provide users with a more comfortable environment in virtual space. As a case study, the authors have applied the system to Sports CAI, in particular a Sports Image Training System for skiing, and an experimental prototype system has been developed. The system consists of weight measurement devices, ski scene display, and data display. According to the movement of the skier displayed on the screen, trainees can control their weight positioning for skiing. The system gives some instructions for improving skiing on the basis of weight data. The new image training method was realized by displaying psychological and physiological data in a virtual environment and by feedback of the data through real time visual information.
