Abstract
In this study, the design method of the surface shape where the tactile sense was taken into consideration was developed. In this method, tactile response is evaluated by considering a friction coefficient and a surface temperature. The optimization problem is solved using the Convex Linearization method (CONLIN). However, many optimum solutions exist and are dependent on an initial design. Therefore the design in consideration of 1/f fluctuation was performed by giving 1/f fluctuation to an initial state. Several examples show the change of surface shape to the various conditions.
