| Abstract | The placement of a point in the median vertical plane under the influence of a moving optical environment was tested in 12 subjects. It was found that the median plane was displaced in the same direction as the movement of the visual environment when the environment was moved at speeds ranging from 9 plus or minus 1 radians/minute to 45 plus or minus 1 radians/minute. It was established that unidirectional movements of the total optical environment always caused a spatial disorientation with respect to external visual reference points. |
