着座型揺動装置のピッチ回転による擬似的な起伏形状知覚

抄録

A great number of driving simulators with visual presentation have been developed, but little is known about the perception of a topographic surface induced by visual and vestibular stimuli when a user runs over a bump or hole. In this paper, we conducted a user study to assess how congruence or incongruence of visual and vestibular shape cues influence the perception of a topographic surface. Experimental results show that the vestibular shape cue contributed to making the shape perception more than the visual one. The results of a linear regression analysis showed that performance with visual unimodal and vestibular unimodal cues could account for that with visuo-vestibular multimodal cues.
