Abstract
Relationship between skin displacement and subjective sensation is indispensable for the design of tactile feeling display. Previous works on the observation of the skin displacement mainly used flat glass plate and a camera. However, the flat glass is not a representative tactile texture that we daily touch. We developed a system that can observe interaction between textured surface and finger skin by using technique known as index matching. The textured plate is immersed in the oil with the same refractive index, so that the texture became invisible. The finger skin is printed with markers, and its movement is analyzed by image processing. We also show a preliminary result of the observation when finger strokes on 0.5 mm interval grating.
