Some species of reptile, herbivore and fish have specialized organs of vision to control both eyes independently and perceive images of surrounding environment for predatory behaviors or avoidance of dangers. Chameleons locate the prey with large and independent saccades of the highly mobile eyes. In contrast, Human cannot control both eyes independently except for convergences or divergences, and cannot perceive independent view fields for both eyes because motor system and cognitive functions of the human differ from those of chameleons. But we assumed that the human becomes able to perceive the images for both eyes and control visual axes with the appropriate device. In this paper, we describe a comprehensive system to provide two independent view fields to both eyes of human by combining two CCD cameras independently controlled and a head-mounted display. This system is composed of a camera positioning system, a 3D tracking system, and a display system. The camera positioning system controls postures of two platforms equipped with CCD cameras independently, which are mounted on right and left both side of the helmet. Desired angles were computed from coordinates of three-dimensional positions sampled by 3D tracking system. Position sensors of the tracking system were set on the fingers of both hands of the user. Each camera tracked the movement of the finger so that view fields could take any arbitrary direction. Visions taken by CCD cameras were projected onto the head-mounted display, which was equipped with two monocular display modules ahead of right and left eye. The system was tried out on several subjects. Most of subjects became able to control two different view fields independently after some practice. Through the trial use, it was thought that the system has the capability to be used for the study of visual perception and to have some practical applications.
