Abstract

Visually induced self-translation is called linear vection, while visually induced self-rotation is called circular vection. Impressions of circular vection and linear vection were measured using flow patterns presented on a flat screen. Subjects reported strong circular vection when the flow simulated a projected pattern of a rotating cylinder, which had gradients in speed and direction of moving elements on the screen. When speed gradients in a horizontal dimension were removed while not changing the direction distribution on the screen, strong circular vection was still reported. On the other hand, when the motion direction of all elements was the same (horizontal), having speed gradients, the circular vection was weak. The impression of linear vection showed the opposite trend. This result indicates not a speed distribution pattern but one of a two-dimensional direction on the retina determines the type of vection.
