Abstract
Giving a feel to a virtual object is very effective, in that it can be improved in operability and reality. Recently, giving a sense of touch by using a visual illusion has been attracting attention, as a way to be given a sense of touch without going through the equipment. However, it has not been quantified about the relationship of tactile and visual, and there is a room for study in its augmentability. In this study, we investigate how much the vision contributes to the tactile. In addition, we propose three methods for providing a new finger tactile sense only by augmentation of visual information.
