Abstract
A system for evaluating tolerance to high acceleration as a function of visual field perimeter and psychomotor tracking ability. A semicircular array of light-emitting diodes (LED's) subtend the lateral field of view of a subject. Pairs of opposed LED's are sequentially illuminated inwardly or outwardly at a programmed rate. A control stick manipulated by the subject provides a nulling signal for maintaining a desired pair of LED's illuminated.
