Tactile sensation presentation apparatus, tactile sensation presentation method, drive signal generation apparatus, and drive signal generation method

摘要

The tactile sensation providing apparatus (400) includes a plurality of actuators (102) for vibrating the panel (101), a touch information acquisition unit (103) that acquires a plurality of touch positions on the panel (101), and a plurality of touches. A tactile sensation presentation determining unit (104) that determines a first touch position that presents a tactile sensation from among the positions, and the panel (101) vibrates according to the first tactile sensation signal at the first touch position, and the panel at the second touch position. (101) is a signal for driving each actuator (102) so as to vibrate smaller than the first touch position, and a transfer characteristic from each actuator (102) to or near the first touch position, and A drive that acquires a signal generated by using a transfer characteristic from each actuator (102) to or near the second touch position as a first drive signal. And a signal acquisition section (402).
