Abstract:

The problem of disorientation in a moving optical environment was examined. Egocentric disorientation can be experienced by a pilot if the entire visual environment moves relative to his body without a clue of the objective position of the airplane in respect to the ground. A simple method of measuring disorientation was devised. In this method changes in motor activity were recorded for assessing optically induced disorientation.

Subjects were placed into an optokinetic drum which excluded any stationary objects from view. Within the non-moving drum the subject walked straight back and forth with open eyes. In the experimental situation the drum was rotated at various constant speeds. The subjects were requested to walk straight forward and backward while their walking pattern was traced.
