Résumé
In visual perception, the kinetic depth effect refers to the phenomenon whereby the three-dimensional structural form of an object can be perceived when the object is moving. In the absence of other visual depth cues, this might be the only perception mechanism available to infer the object's shape. Being able to identify a structure from a motion stimulus through the human visual system was shown by Wallach and O'Connell in the 1950s through their experiments. For example, if a shadow is cast onto a screen by a rotating wire shape, a viewer can readily perceive the shape of the structure behind the screen from the motion and deformation of the shadow. There are two propositions as to how three-dimensional images are perceived. The experience of three-dimensional images can be caused by differences in the pattern of stimulation on the retina, in comparison to two-dimensional images. Gestalt psychologists hold the view that rules of organization must exist in accordance to the retin
