Abstract

A head-mounted-display system for virtual reality is developed, which is mainly comprised of a pair of viewing lenses together with LCDs to provide the stereoscopic image, and a tracking device to detect the motion of the head. Each viewing lens contains 4 optical elements, and can give a 120 degree(s) field of view for each eye when used with a 2.2' LCD. The tracking device consists of a 3-axis fluxgate magnetometer and a pendulum, which determines the orientation angles of the helmet. Another version of the tracking device capable of measuring 6 degrees of freedom movement of the helmet is currently under development.
