Résumé / Abstract
RECENT STUDIES HAVE SHOWN THAT THE PATTEUR OF OPTICAL FLOW RESULTING FROM THE OBSERVER'S SELF MOTION THROUGH A STABLE ENVIRONMENT IS USED BY AN OBSERRVER TO ACCINATELY CONTROL HIS/HER MOVEMENTS HAVEVER, LITTLE IS KNOWN ABOUT THE PERCEEPTION OF ANOTHER VEHICLE DURING SELF MOTION. IN EXPERIMENTS USING VISUAL SIMULATIONS OF CAR DRIVING, WE SHOW THAT OBSERVERS ARE QUITE ABLE TO DETECT THE PRESENCE OF A MOVING OBJECT DURING SELF-MOTION HOWEVER, THE PERCEPTION OF THE OTHER CAR'S TRAJECTORY APPEARS TO BE SHONGLY DEPENDENT ON ENVIRONMENTAL FACTORS (SHAPE OF THE ROAD, PRESENCE OF A ROAD SIGN NEAR THE INTERSECTION) THESE RESULTS SUGGEST THAT LOCAL AND GLOBAL VISUAL FACTORS DETERMINE THE PERCEPTION OF A CAR'S TRAJECTORY DURING DELF-MOTION
