We developed a prototype of simple virtual reality (VR) system as a support tool to overcome fear of heights. The system consists of one personal computer, one projector and a hemisphere dome screen with the diameter of 1 m. It is a dome-screen type VR system because it makes little burden both to a medical doctor (or a counselor) and to a client. The dome screen is a low-cost type made milky-white plastic. We adopted rear projection using only one projector and could get an image with an effective field of vision. We can use a picture or a movie took from a personal-type digital camera. As for the correction of image distortion, we made the software tool originally. Therefore, the running cost is also low and the operation is easy. As the result of evaluation experiment, we confirmed that the system made a feeling of devotion with little sense of incongruity. It seems to show the possibility that the simple VR system can be utilized as a medical service tool of the spread type.
