Relation between perceived depth and perceived motion in uniform flow fields.

Abstract
Three experiments are reported that examined the nature of the perceptual linkage between perceived depth and perceived motion in bidirectional uniform velocity fields. In such displays there is systematic misperception of both the speeds and directions of motion of visual objects. It was found that the speed and the direction of perceived motion were related to objective velocity by the addition of a uniform velocity component across the visual field. It is proposed that this uniform component may be the result of compensation for incorrectly registered ocular rotation and that such an account may also apply to classical center-surround induced motion effects.
