DISPLAY-INTERACTIVE EYE MOVEMENT MONITOR BASED UPON IMAGE PROCESSING TECHNIQUE

THE PROPOSED UNOBTRUSIVE TECHNIQUE FOR MONITORING EYE MOVEMENTS AND DETERMINING THE FIXATION POINT ON THE DISPLAY SCREEN IS BASED ON THE STATE-OF-THE-ART REAL-TIME IMAGE PROCESSING SYSTEM EQUIPPED WITH FAST SERVO-CONTROLLED MECHANISMS FOR THE ADJUSTMENT OF THE VIDEO CAMERA'S FOCUING, ZOOMING, AND ORIENTATION IN SPACE. THE FEASIBILITY OF AVAILABLE UNOBTRUSIVE TECHNIQUES OF EYE-MOVEMENT TRACKING (I.E., CORNEAL REFLEX, DOUBLE-PURKINJE, AND PUPIL ELLIPTICITY), IN CONJUNCTION WITH THE IMAGE PROCESSING SYSTEM WILL BE STUDIED. SPEED, RESOLUTION, RELIABILITY, COMPACTNESS AND SELF-CALIBRATION CAPACITY OF EACH METHOD WILL BE DETERMINED. FACTORS SUCH AS EASE OF USE, OPERATOR,S COMFORT, AND COST WILL BE CONSIDERED. BASED ON THESE STUDIES, THE APPROPRIATE SYSTEM WILL BE SELECTED AND OPTIMAL DESIGN PARAMETERS WILL BE DETERMINED FOR THE FINAL DESIGN AND CONSTRUCTION TO BE CARRIED OUT IN PHASE II EFFORTS.
