Tactile sense presentation device and method of driving tactile sense presentation device and electrode connection control
Abstract:
X and Y electrodes arranged on a support substrate of the tactile sense presentation device are divided into M groups (here, M≥2, M=4 in FIG. 14). When a presentation content of a tactile sense transits from the N-th frame to the (N+1)-th frame, the device, first, sets electrodes belonging to a group 1 to a floating state for a predetermined time and then, connects each electrode to an AC voltage signal source or the ground so as to present a tactile sense in the (N+1)-th frame. The device sequentially performs this operation for each group, and, when the operation of group M ends, transition between frames ends, and movement of the target area in which a texture sense is presented is completed. There is no case where all the electrodes are in the floating state together, and there is no interruption of the texture sense.
