In this papar, we propose a Virtual Reality (VR) Relax/Refresh system employing physiological feedback whose purpose is getting rid of stress and recovering from mental fatigue in a short time.
First, the concept of the system and the necessary functions are discussed from the viewpoint of physiology and VR technology.
Secondly, a prototype system developed on the basis of the concept is shown. It is composed of a massage lounger, a heart rate sensor, a head-mounted-display (HMD), a VCR, and an interface circuit which controls the massage chair and generates threedimensional images. The developed system also has functions such as sleep judgement algorithm and physiological feedback mechanism which varies the stimulations to the living body according to the measured heart rate data.
Finally, the system is evaluated by measuring electrocardiograms of 5 subjects and calculating power spectrum of fluctuation on R-R intervals of the waveform. The result shows the system more effective than just having a rest with eyes ope
