1. G force response measuring apparatus comprising the combination of:
- a first array of visual stimulus elements dispersed around the preripheral view area of a test subject;
means for energizing said first array elements to a visual stimulating state thereof according to a first random time pattern;
a second array of visual stimulus elements dispersed around the peripheral view area of said test subject, each second array element being located adjacent a first array element;
means for energizing said second array elements to a visual stimulating state thereof in a second test subject controlled pattern tracking said first pattern to the best degree attainable by said test subject; and
means for determining the difference error between said first and second patterns.

Abstract
A G force acceleration effects monitoring apparatus involving a pair of LED or other visual stimulus arrays, one randomly patterned by an electronic driving apparatus and one patterned by the manipulation of a G force test subject. The electronic driving apparatus preferably includes a sum of sines algorithm and the test subject manipulations are received preferably from a joystick controller. Mounting of the apparatus in a centrifuge gondola and also in off-line training stations and use of the invention by animals are also disclosed.

18. A method of determining the endurance limit of a human test subject to acceleration G forces comprising the steps of:
-
moving a first visual stimulus randomly about the peripheral extending view field of said test subject; tracking the position of said first visual stimulus with a test subject-controlled simultaneously observed second visual stimulus that is position movable into and out of coincidence with said first visual stimulus in response to said test subject control; and sensing the loss of stimulus tracking ability in the test subject peripheral view field with G force exposure.

19. Apparatus for measuring the G force response of a test subject comprising:
-
first visual stimulus means movable in location around the peripheral view field of said test subject; means for moving said first visual stimulus means randomly about said peripheral view field; second visual stimulus means movable in location around said peripheral view field in response to control by said test subject for tracking the position of said first visual stimulus means in response to control by said test subject; and means for sensing the G force-induced loss of stimuli tracking capability in far peripheral view field areas of said test subject. - View Dependent Claims (20, 21, 22, 23)
