Psychophysical Influence on Tactual Impression by Mixed-Reality Visual Stimulation

This paper describes the influence of visual stimulation on the tactual sense in a mixed-reality environment; i.e., how a tactual impression of a real object is affected by seeing a superimposed image of a different type of material. If the behavior and the extent of such an influence, a sort of illusion, are investigated in detail, the objects composed of a limited variety of materials can be perceived differently. This would be useful in the field of digital engineering. Therefore, we performed various experiments systematically.
