Abstract
This paper describes micro pattern tactile samples to characterize tactile feeling. We perceive many tactile sensations such as rough, bumpy, smooth by our skin. At present, what kind of parameters of texture relates to these sensations is not clear. We designed and manufactured micro pattern tactile samples to investigate the relationship between the surface characteristics and our tactile sensations. The tactile samples presented in this work are made of SU-8 and have micro striped patterns. The effects of the width and pitch of the stripes on the tactile feeling were investigated. In distinguishing the roughness, the experiments deduced that width was a more dominant factor over the pitch.
