This invention relates to an eye movement tracking display for presenting a realistic visual image to a person.
2. Description of the Prior Art
Head mounted displays have been developed for visually presenting a person with a scene taken by a TV camera or with a realistic virtual image generated in a computer and displayed graphically. The head mounted display is equipped with a pair of independent TV monitors disposed one in front of each eye so as to enable the viewer to perceive a 3D sensation with stereo effects.
With such a head mounted display, when images taken by TV cameras or graphic images generated on computer displays are manipulated in accordance with movements of the viewer's head detected by a goniometer or magnetic means, the viewer is given the sensation of viewing the environment imaged by the cameras from the position of the camera or of being present in the world of imagery presented by computer graphics. Since the images are presented to the left and right eyes by two small image displays, however, the frames of the image displays are constantly within the viewer's field of view. This detracts from the sense of reality of the experience.
It is known that most human beings have a field of vision that extends.+-.40.degree. from the central axis of the eyeball. Therefore, unless the head mounted display is equipped with TV monitors whose picture areas are large enough to cover this region, the viewer will be able to see the monitor frames and be given the impression of viewing the displayed images as if peering through the frames. One conceivable way of overcoming this problem is to use TV monitors with picture areas large enough
atoms, preferably at least about 50 carbon atoms. The dispersant is described as having better hydrolytic constancy and shear stress constancy, produced by the chemical reaction of certain maleic anhydride - olefin copolymer with certain polyamines.

 With such a pass mounted display, when images taken by TV cameras or graphic images render on computer displays are manipulated in accordance with movement of the spectator's pass detected by a goniometer or magnetic means, the spectator is given the sensation of viewing the environment imaged by the cameras from the position of the camera or of being present in the world of imagery present by computer graphic.
