An eye movement tracking type head mounted display for virtual reality system: evaluation experiments of a prototype system

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, namely to present a wider view angle and higher resolution image, 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 structure of the proto-type display system is explained, and the presentation method of the high resolution image using the prototype system is considered. Also, some evaluation experiments are introduced to demonstrate the effectiveness of the proposed idea
