Binocular head mounted display with eye movement tracking function: development of the prototype and its application

This paper describes a head mounted display that can present images with high reality. The head mounted display (HMD) is often used on tele-robotics systems as visual presentation equipment. In such a tele-robotics system, an operator works on the basis of visual information presented by the HMD. In order to work precisely, high reality images are demanded. In order to present high reality images, a wide view angle and high resolution images need to be presented. But in conventional HMDs the field of view is narrow or the resolution is low, because of the restriction of the scanning line of a display. For that reason, the usage is limited. In order to solve those problems, we are developing the eye movement tracking type HMD (EMT-HMD) that can present the wide view angle and high resolution images of the environment although conventional displays are used. The principle is that a small image of high resolution is present in a narrow range of view point and present a wide image of low resolution in the perimeter by using two displays. In this paper, we examine a system which tracks the movement of eyes in a two dimensional range. The structure of a trial production system is explained. Also some evaluation experiments are introduced.
