[Invited Talk] Determination characteristics for vection yielded by two optical flows

Abstract (in Japanese) (See Japanese page) 
(in English) We investigated the characteristic of speed of vection occurred from two optical flows that were overlapped in the same space at different speed. When the speed difference between two optical flows was small, the speed of vection linearly increased with the ratio of the spatial distribution densities of two optical flows. On the other hand, when the speed difference between two optical flows was large, the slower optical flow had greater contributions to the speed of vection. This characteristic can be predicted by a model that sum up speeds of two optical flows weighted by the ratio of the spatial distribution densities of two optical flows. In addition, this characteristics of the speed of vection agree with the result of our previous research which investigate the effect of vection inducing stimuli on the change in driver’s speed sensation.
