ABSTRACT:
A gaze point tracking apparatus is provided having a comparator that receives a video signal corresponding to an eye image or a beacon image. The comparator produces a processed video signal that consists of two signal levels. A video processor detects and measures transitions between the two signal levels. The detected transitions are used to determine the location of a gaze point on a display.
