Abstract:
A tactile presentation device comprising: a contact face; a plurality of electrodes arranged along the contact face; a first control unit controlling operations of the electrodes for detecting contact or approach of an object toward the contact face; a second control unit controlling operations of the electrodes for presenting a tactile sense to the contact face; and a third control unit causing a part of the plurality of the electrodes to be controlled by the first control unit, sequentially changing the electrode to be controlled by the first control unit to another electrode among the plurality of the electrodes, and causing electrodes other than the electrode that is controlled by the first control unit to be controlled by the second control unit.
