Vection is an illusory self-motion perception induced by coherent motion in a wide visual field. We measured vection for two kinds of subjects who could or could not control the optic flows (the driver and passenger). Vection strength was always stronger in the passengers than in the drivers. These results could be explained by the predictability of the optic flow and active behavior with correct feedback.
