THE UTILITY OF PERIPHERAL VISION TO MOTOR VEHICLE DRIVERS
The study involved (1) the determination of the frequency of mirror usage by subjects in traffic maneuvers using their own cars and the associated extent of head turn during mirror usage, (2) the measurement of peripheral detection angles (PDA) as a function of target contrast, target speed, foveal attentional load, eye and head position, and subject age in a laboratory simulation, and (3) field validation studies. In Task 1, 45 subjects using their own vehicles yielded 4,400 mirror samples and associated head movements. Highlights include: (1) Greater head movement is associated with the left mirror compared to the inside mirror. The percent head turn (degree head turn/degrees to mirror) was 65% for the outside mirror versus 50% for the inside mirror. (2) Age differences were significant with older subjects exhibiting greater head movement for both mirrors.
