Abstract
When exposed to a large moving visual display a person experiences illusory self motion (vection). Using specialized devices, vection and induced visual motion were studied in three sets of experiments. In the first experiment, a neglected aspect of vection has been investigated. This concerns the relation between illusory visual motion of stationary objects and illusory self motion induced by motion of a visual scene. Two distinct components of induced visual motion were measured; exocentric induced motion which causes a stationary object to appear to move with the self and egocentric induced motion which causes an object to appear to move with respect to the self. The second experiment was designed to reveal the extent to which vection depends on the presence of stationary objects in the field of view and to explore what types of relative motion between the moving display and the stationary objects most strongly induce vection.
