Abstract
When an observer moves through a static 3-D scene, the retinal image deforms in a way that depends both on the scene geometry and on the observer’s motion. These deformations thus provide information about the scene geometry and the observer’s motion (Gibson, 1950). Human observers can in many cases perceive the direction of 3-D heading from retinal image motion, even under passive viewing such as watching TV. Performance depends on several factors, such as whether there is sufficient depth variation in the scene and whether the image motion is due to real or simulated eye movements. A variety of scene geometries have been used ranging from a single ground plane to a “3-D cloud of dots”. A recent review of human heading perception can be found in (Warren, 1998).
