ジェスチャ操作に適した機械の操作音の設計と評価

抄録

Operation sounds for machine products have been designed to transmit or caution correct information to users. The user operation for the machine product has changed from a button operation to a touch or gesture operation according to the evolution of information devices. However, the operation sound for the machine product has not been changing since the button operation has kept a main stream. The purpose of this study is to evaluate for combination between the gesture operation and the operation sound for new information devices. It is clarified that the relationship between the gesture operation and the operation sound by carrying out evaluation experiments using seven types of typical gesture operation and the different dimensional sounds, which are an ON/OFF temporal pattern sound, a pitch variation sound, and a movement of sound image. It is experimentally verified that the pitch variation sound and the movement of sound image are important factors for the gesture operation of the machine product.
