Abstract

Abstract An eye movement tracking display comprises an image generator having wide view angle image generation means and narrow view angle image generation means and functioning to produce an image for display in a wearer's field of vision, an image display for displaying the image produced by the image generator to the wearer, and an eye movement detector for detecting movement of the wearer's eye. The image display comprises an image display panel for displaying a low-resolution image received from the wide view angle image generation means, image processing means electrically connected with the panel for erasing the portion of the low-resolution image displayed at the region of the panel to which the wearer's eye is directed, and an image transmission element positioned behind the image display panel for directing a high-resolution image received from the narrow view angle image generation means to the erased region of the panel.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 182 words
An eye movement tracking display comprising: an image generator having wide view angle image generation means and narrow view angle image generation means and functioning to produce an image for display in a wearer's field of vision, an image display for displaying the image produced by the image generator to the wearer, and an eye movement detector for detecting movement of the wearer's eye, the image display comprising a transparent liquid crystal panel having a front surface directed to the wearer's eye for displaying a low-resolution image received from the wide view angle image generation means, image processing means electrically connected with the eye movement detector for receiving an output signal from the eye movement detector and electrically connected with the panel for erasing by the output signal a portion of the low-resolution image displayed at a region of the panel to which the wearer's eye is directed, and an image transmission element positioned behind the panel for directing from behind the panel a high-resolution image received from the narrow view angle image generation means to the erased region of the panel.
Claim 2
Dependent Claim 182 words
An eye movement tracking display comprising: an image generator having wide view angle image generation means and narrow view angle image generation means and functioning to produce an image for display in a wearer's field of vision, an image display for displaying the image produced by the image generator to the wearer, and an eye movement detector for detecting movement of the wearer's eye, the image display comprising a transparent liquid crystal panel having a front surface directed to the wearer's eye for displaying a low-resolution image received from the wide view angle image generation means, image processing means electrically connected with the eye movement detector for receiving an output signal from the eye movement detector and electrically connected with the panel for erasing by the output signal a portion of the low-resolution image displayed at a region of the panel to which the wearer's eye is directed, and an image transmission element positioned behind the panel for directing from behind the panel a high-resolution image received from the narrow view angle image generation means to the erased region of the panel.
