INFLUENCE OF VESTIBULAR STIMULATION AND DISPLAY LUMINANCE ON THE PERFORMANCE OF A COMPENSATORY TRACKING TASK.

Abstract

Loss of acuity for visual details in aircraft during unusual maneuvers has been documented. Recent investigations of this problem have served to define the magnitude of semicircular canal stimulation necessary to produce nystagmus of sufficient strength to degrade visual acuity. Present work extends former observations by investigating the effects of levels of illumination during semicircular canal stimulation on the performance of a task requiring vision. The illumination levels were selected to encompass the range used in aircraft cockpits. A compensatory tracking task with an aircraft instrument as the display provided an indirect measure of this loss of visual acuity and a direct practical measure of performance. (Author)
