ABSTRACT:
The tracker determines a vision vector for an eye of an operator. The device generally comprises: a video camera oriented so as to observe an eye of an operator for obtaining an image of the eye; camera interface electronics and image processor for digitizing the image of the operator's eye and for analyzing the digitized image for determining therefrom a plurality of points determinative of the iridal ellipse, the points being on the boundary between the eye's sclera and iris as represented by different light intensities; and a processor for utilizing said information and an estimate of the diameter of the iris in formulating an estimated optical axis vector for the eye. If the position and orientation of the camera is known relative to the operator's eye, then the pupillary ellipse can be used instead of the iridal ellipse. The tracker of the invention can be used as a mouse emulator attached to a mouse port of a personal computer system.
