QUANTITATIVE EVALUATION OF OPTICALLY INDUCED DISORIENTATION,
Abstract
The purpose of this study was to establish quantitatively and systematically the association between the speed of movement of an optical environment and the extent of disorientation experienced by an individual viewing this environment. The degree of disorientation was determined by measuring the angle by which an individual deviates from a straight path when he walks back and forth within a rotating optokinetic drum. The correlation between the speed of the moving optical environment and the amount of disorientation indicates that greater disorientation occurs when the optical environment moves faster. However, as the environment moves with increasing velocities the objectively measurable degree of disorientation becomes relatively less. It appears that at faster movements of the optokinetic drum, the subjects become increasingly more cognizant of their disorientation and attempt to compensate for it. At velocities of less than 20 radians/min. most subjects are disoriented in their motor activity without being aware of it. (Author)
