Regulating focus in accordance with relationship of features of a person's eyes
First Claim
1. A system for providing an at least partially in-focus image of a feature at which a person is gazing, comprisingvariable-focus means for providing an image of the feature on a display screen;
- means for indicating a spatial relationship of features of the person'"'"'s eyes; and
means for regulating the variable-focus means in accordance with the indicated relationship.

Abstract
The focus of variable-focus lenses in eyeglasses worn by a person is regulated in accordance with an indication of a spatial relationship of features of the person'"'"'s eyes to provide an at least partially in-focus image of a feature at which the person is gazing.. The lenses are nematic liquid crystal display devices. Light reflected off of each of the person'"'"'s eyes is detected to provide data indicating the respective dispositions of the person'"'"'s eyes; and the combined data for both eyes is processed by a neural network in a computer to provide focus-control signals for setting the focus of each lens. At least partially in-focus images are also provided of features at which a person in gazing (a) through goggles of a three-dimensional virtual reality system, (b) on a monitor that perceptually simultaneously displays different features with different degrees of focus as though they were at different distances from a person viewing the monitor, (c) on a monitor displaying remotely generated images and (d) through a view finder of a camera.
