Method for presenting tactile sensation and device therefor

摘要

A tactile sense presentation device includes first electrodes covered with an insulating film and arranged on a plane; second electrodes arranged on a plane with tops exposed to outside; and a control unit performing a first operation in parallel with a second operation. The first operation is for applying temporally changing first voltages to a part of the first electrodes to generate electric fields which are changed by the part of first electrodes, and the second operation is for applying temporally changing first electric currents to a part of the second electrodes to cause the electric currents to flow from the part of the second electrodes to second electrodes which are different from the part of second electrodes via electric conductors. The first electrodes and second electrodes are arranged not to overlap each other.

主权项

1. A tactile sense presentation device to engage with an object, the tactile sense presentation device comprising:
a plurality of first electrodes arranged on a first plane; an insulating film covering the plurality of first electrodes; a plurality of second electrodes arranged on a second plane, respective tops of the plurality of second electrodes being uncovered by the insulating film; and a controller configured to:
(i) cause a temporally-changing first voltage to be applied to a first part of the plurality of first electrodes to generate a temporally-changing electric field in the object contacting the insulating film above the first part of the plurality of first electrodes;(ii) cause a temporally-changing first electric current to be applied to a first part of the plurality of second electrodes to cause the first electric current to flow through the object contacting the first part of the plurality of second electrodes; and(iii) cause a temporally-changing second voltage to be applied to a second part of the plurality of first electrodes, and detect a voltage between the second part of the plurality of first electrodes and a third part of the plurality of first electrodes to detect position of the object.
