Development of an eye movement tracking type dead mounted display: system proposal and evaluation experiments

This paper describes a head mounted display (HMD) system which can present realistic visual images of the environment. There are several types of commercial HMDs for virtual reality systems. One of the problems of their systems is that the screen size is small in order to keep the image resolution high. Therefore, the screen frame and displayed images overlap and impair the sense of reality. In order to improve it, a new type of HMD is proposed. The idea is based on superimposing small, high resolution images on wide, low resolution images. The high resolution images are presented only near the center of human retina, according to the motion of eyeball detected. In this paper, the design of the optical system and image control system is explained. Also, some preliminary evaluation experiments using a prototype system are introduced to demonstrate the effectiveness of the proposed idea.<<ETX>>
