<P>PROBLEM TO BE SOLVED: To provide a tactile stimulation generation device capable of easily giving a desired electric stimulus to a user, the device being provided with high reliability and high safety. <P>SOLUTION: A tactile stimulation generation device 1 for giving an electric stimulus to a fingertip 40 of a user is used by arranging a tactile stimulus generating sheet 4 including an insulating layer 2 provided with a group of tactile generation electrodes 3, on a top surface of a coordinate input device 10. When the fingertip 40 comes close to the insulating layer 2, positive electrodes and negative electrodes in the group of tactile generation electrodes 3 to which differential voltage is to be applied, and the fingertip 40 are capacitively coupled with each other. Accordingly, a part of currents flowing from the positive electrodes to the negative electrodes passes through the fingertip 40, so that the currents give the stimulus to the user. At the time, the differential voltage is applied while current amount control is performed so that an amount of currents flowing into the fingertip 40 from the positive electrodes becomes the same as an amount of currents flowing out from the fingertip 40 into the negative electrodes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
