Visual Phenomena Produced by Binocularly Disparate Dynamic Visual Noise.
Abstract
The use of helmet-mounted displays in flight simulation requires that different visual stimuli be presented to the two eyes. Such disparate stimulation may result in perceptual problems which could adversely affect simulator training. A series of four experiments addressed several perceptual problems associated with the use of binocularly disparate stimuli. The stimulus used in all four experiments was the dynamic visual noise (DVN) stereophenomenon produced by viewing a detuned television receiver with the input to one eye attenuated by a light filter. The result is the percept of several counterdirectional dot-planes separated in depth. The purpose of the basic visual research reported here is to further elucidate the visual mechanisms underlying movement aftereffects (Experiment I), binocular rivalry (Experiment II), perceived visual acceleration (Experiment III), and vergence and accommodation to perceived depth (Experiment IV). Each of these phenomena was induced by a form-free texture stimulus perceived as moving in planes located at various distances from the observer.
