High resolution, wide view angle head mounted display using eye movement tracking: system structure and evaluation experiments

This paper describes a head mounted display (HMD) which can present visual images with high reality using the characteristics of the human eye. The HMD has received considerable attention as vision presentation equipment for virtual reality or telerobotics. However conventional HMDs have problems that those images are narrow view angle and low resolution, because those displays have a fixed number of scanning lines. In order to improve it, an eye movement tracking type HMD (EMT-HMD) was proposed. The EMT-HMD can present wider view angle and higher resolution compared with the conventional HMDs, though conventional display devices are used. The principle is that a small high resolution image is superimposed on a wide low resolution image using two conventional display devices. A small, high resolution image is presented at small area around the view point according to the output of the eye movement detector. On the other hand, a wide, low resolution image is presented at its peripheral wide area. In this paper, the structure which can track eye movement in 2-dimension is discussed. Then, the structure of the trial production system, is explained. Also, some evaluation experiments are be introduced to confirm the effectiveness of the proposed idea.
