遠近法的錯視によるPseudo Haptics効果の検証

抄録

Pseudo Haptics is a method of presenting tactile sensations without using any haptic device. However, Pseudo Haptics is problematic because of its limited effect size and significant differences in effect among individuals. To improve them, we investigated the effect of perspective increase using the line perspective illusion that affects Psuedo Haptics. For this purpose, we examined the perceived distance to the object in VR space using the linear perspective illusion and then the perceived weight and movement distance when the object was pushed. The results showed that the illusion could not significantly change the perceived distance and that it was difficult to improve the weight perception by Pseudo Haptics. This may be because the observers could not consciously perceive the illusion, and it was difficult to notice the illusion due to the small change in the visual object caused by the line perspective method.
