Presentation of Movement Parallax on a Fixed Display.

Three-dimensional (3D) visualization is a key component in the human interface for teleoperation. A 3D visualization system usually implies a system which uses convergence and binocular parallax. It has been found, however, that spatial sensitivity using these techniques is highly inconsistent among individuals. In this paper, we discuss the presentation of the movement parallax (MP), which is another aspect of 3D visualization. In order to present MP, the display device must follow the movements of the human's head. A natural choice here is to use a head-mounted display (HMD). For practical teleoperation, however, a HMD is found to be too stressful for the operator. In this paper, we propose a technique to present MP on a large fixed screen. A prototype is developed, and experiments show that the MP is very effective in improving the operator's ability to recognize the teleoperation environment.
