THE EFFECT OF DIRECTION AND VELOCITY OF RELATIVE MOTION UPON DYNAMIC VISUAL ACUITY.
Abstract
In this study, human dynamic visual acuity was related to relative stimulus velocity when the stimulus motion contained a vector of motion toward the observer. The specific parameters investigated, and their effects upon visual acuity were: (1) Direction of stimulus motion across the retina; (2) Angular velocity of the stimulus perpendicular to the line of sight; (3) Rate of approach of the stimulus directly toward the observer; (4) Exposure time of the stimulus; and (5) Stimulus pattern. The results were discussed in terms of their application to object recognition from automobiles and low-altitude, high-speed aircraft. (Author)
