Abstract
In this research, by using three-dimensional shape which realizes the operation result on the interface, visual information and tactile information of three-dimensional shape are made to function. By doing so, the prediction of the result when manipulating the interface matches the actual result. In this research, we focused on crossfade switching of sounds. As a result of the verification, it turned out that the interface which realized the operation result has usefulness from a visual and tactile point of view.
