  • Publication number: 20200050348
    Abstract: A first operation region 11 for providing a first tactile sensation and second operation regions 12_U and 12_D for providing a second tactile sensation are arranged adjacent to each other. when a detection unit 20 detects a slide operation from the first operation region 11 to the second operation region 12U or 12D, an operation control unit 30 outputs a second operation signal different from a first operation signal output depending on a movement distance of the slide operation on the first operation region 11. Therefore, the second operation signal is output when the degree of operation is not sufficient even by performing a slide operation within the first operation region 11, and the movement of the finger stops at a place where a change from the first tactile sensation to the second tactile sensation occurs. As a result, it is possible to allow a user to perform an operation of a degree of operation desired by the user without performing the slide operation several times.
