  • Patent number: 4145122
    Abstract: This invention relates to an apparatus for monitoring the position of the eye and generating an electrical signal based upon its displacement from a neutral position, such apparatus being characterized by a pair of eyeglasses modified to provide an infrared mirror on the inside surface of one lens, an infrared light emitting diode located on the nosepiece in position to produce a virtual image thereof within the wearer's eye as reflected from the infrared mirror, and an image detector mounted on the bow of the eyeglasses adjacent the mirror filtered to respond only to infrared light and effective to locate the position within the eye of the reflected LED image. The invention also encompasses a novel detector which, not only monitors the position of the eye but, in addition, through the use of a photosensor array, provides the means for generating a signal whose magnitude is proportional to the displacement of the eye from its centered or reference position.
