Title: EYE/GAZE TRACKING SYSTEM AND METHOD
Abstract:
An eye/gaze tracking system (100) receives first and second image streams (DIMG1, DIMG2) in first and second processing lines (110; 120) respectively. The first processing line (110) has at least one first processor (P1, P11, P12) generating a first set of components of eye-specific data (p1LG, p1LP, p1RG, p1RP) for producing eye/gaze data (DE/G). The second processing line (120) has at least one second processor (P2, P21, P22) generating a second set of components of eye-specific data (p2LG,p2LP, p2RG, p2RP) for producing the eye/gaze data (DE/G). The eye/gaze data (DE/G) describe an eye position and/or a gaze point of the subject (U).
