Abstract: In this study, we focused on roughness of grasped objects and investigated effects of roughness on mechanical responses in fingertip, roughness perception, and gripping comfort during gripping cylinders with grooves. Roughness perception and gripping comfort evaluation of cylinders with different grooves and ridges were obtained from ten participants in grasping experiment. Mechanical responses in fingertip during gripping cylinders with grooves were calculated by finite element (FE) method using fingertip FE model. Results of FE simulation indicated that strain energy density in skin and subcutaneous tissue increased with groove width of cylinders. Additionally, perceived roughness also increased with groove width of cylinder. Hence, strain energy density in skin and subcutaneous tissue seems to contribute to roughness perception. Furthermore, relationships between perceived roughness and gripping comfort evaluation were different among individuals. Specifically, cylinders perceived to be rough tended to be evaluated as discomfort by seven participants, whereas others tended to evaluate as comfort.
