Abstract
A tactile sense presentation device including: a tactile-sense presentation unit having a first working electrode group of a plurality of first working electrodes arranged along a first direction; and a control unit operable to apply a first tactile sense signal having a first waveform to each of the first working electrodes. The control unit applies the first tactile sense signal, in which a phase difference corresponding to a distance between adjacent first working electrodes is applied to the first waveform, to each of the plurality of first working electrodes so as to cause the first waveform to travel along the first direction at a predetermined speed.

A tactile sense presentation device comprising:
- a tactile sense presentation unit including a first working electrode group of a plurality of first working electrodes arranged along a first direction;
- and
- a control unit operable to apply a first tactile sense signal having a first waveform to each of the first working electrodes,
- wherein the control unit applies the first tactile sense signal, in which a phase difference corresponding to a distance between adjacent first working electrodes is applied to the first waveform, to each of the plurality of first working electrodes so as to cause the first waveform to travel along the first direction at a predetermined speed.
A tactile sense presentation method for presenting a tactile sense with a tactile sense presentation device including a tactile sense presentation unit having a first working electrode group of a plurality of first working electrodes arranged along a first direction, the tactile sense presentation method comprising:
- deciding a phase difference corresponding to a distance between the adjacent first working electrodes such that a first waveform travels along the first direction at a predetermined speed, by a control unit of the tactile sense presentation device;
- and
- applying the first tactile sense signal to which the phase difference is applied, to each of the first working electrodes, by the control unit.
