Fishbone Tactile Illusionを利用した触対象の凹凸知覚(触覚とロボット,2007年度 第2回フォーラム)

抄録

Tactile sensation usually provides reliable perception of an object's presence and its surface geometric profile. However, the human tactile perception is not necessarily faithful reproduction of the physical property of an object in real world. Such phenomenon is called as tactile illusion, and it provides a lot of insights about the characteristics of human tactile perception and its mechanisms as like as visual illusion research. Researches on tactile illusions have been reported little by little from the era of Aristotle to present in psychological field, and actively reported by engineers in recent years. It is because that the study on tactile illusions is also helpful for engineers to develop a tactile display, which is an apparatus to (re) produce tactile perception. This article mainly reviews the Fishbone Tactile Illusion as a casework of tactile illusion research in engineering field, then discusses the mechanisms of human tactile perception based on the findings of the illusion, as well as the application of those findings.
