We are studying virtual reality system for “Hyper Hospital”. The “Hyper Hospital” is a medical care system which is distributedly constructed on an electronic information network. In the present report, we discussed a new version of our virtual reality system using a head-position sensor by the ultrasound, and a new head mounted display as the hardware parts of the system. We also developed an object oriented software to construct the virtual world for the Hyper Hospital. For severely disabled patients, we are studying the feasibility of the ERP (event related potential of the electroencephalogram) based human interface. The prototype system of the “Hyper Hospital” developed in the present study was shown to be applicable to the real medical environment.
