  • Publication number: 20150241974
    Abstract: A tactile sensation providing apparatus determines a touched object and stores touch information based on the object in a memory unit 16. When an object in current touch information does not match an object in previous touch information stored in the memory unit 16, the tactile sensation providing unit 12 provides a first tactile sensation. When these objects match each other, the tactile sensation providing unit 12, based on the current touch information and the previous touch information, provides the first tactile sensation or a second tactile sensation, which is different from the first tactile sensation and provided with lower power than that for providing the first tactile sensation.
