Design and Evaluation of Binocular Head-Mounted Displays.

Abstract

It has become necessary to develop a light-weight head-mounted display as a man-machine interface with a sensation of presence in tele-existence teleoperation and virtual-reality technology. Design for such displays needs knowledge of human factor and physiological optics. However, on general method has been proposed yet for the design of such displays. In this paper, we propose a method for designing head-mounted displays, and have developed four light-weight head-mounted stereoscopic full-color displays for remote operation. These displays are designed to give 3 D sensation with a sensation of reality. Two of them are very light weighted, and have wide angle of view, which are designed to teleoperate a mobile robot. The others have a link mechanism to support their weight, and have very fine resolution of view, which are designed so teleoperate a robot for fine manipulation tasks. Dynamic responses of a human operator using these displays are measured by tracking experiments. These results show which parameters of displays are related to dynamic performance. Such parameters are important factors for general design proceduer of head-mounted displays with good dynamic performance.
