摘要
A technique is disclosed of tracking a position of a pupil of a viewer's eyeball, by directing light toward the eyeball and using a portion of the light reflected from the eyeball. In the technique, the detection is performed of the intensity of a reflected light beam which is a portion of a light beam entering the eyeball which is reflected therefrom. An intensity signal indicative of the intensity of the reflected light beam is produced. The pupil position is tracked based on intensity changes of the reflected light beam represented by the intensity signal.
