Does Vergence Influence the Vestibulo-Ocular Reflex in Human Subjects Rotating inthe Dark

摘要

In recent experiments involving acceleration stimuli, researchers instructedsubjects to focus on a visual target while measuring the vestibulo-ocular reflex (VOR) in one eye. These experiments showed conclusively that the VOR is influenced by target distance. We, on the other hand, were interested in investigating the VOR of subjects accelerated in complete darkness. Specifically, we wished to determine the subject's vergence point, which cannot be accomplished using data obtained from only one eye. Hence, a binocular eye-tracking system that works in the dark was required. In the experiment described in this thesis, the subject was rotated in the dark on NAMRL's Coriolis Acceleration Platform.
