PROBLEM TO BE SOLVED: To reduce malfunction of a touch sensor with a vibration function.SOLUTION: A haptics signal generation unit 27 generates a haptics signal that vibrates a resistance film type touch panel 7 by a vibration element 9. A signal conversion unit 25 converts a voltage detected according to pressure points of the resistance film type touch panel 7 into coordinates of the pressure points of the resistance film type touch panel 7. A coordinate acquisition unit 29 acquires the coordinates of the pressure points of the resistance film type touch panel 7 from the signal conversion unit 25 at a predetermined sampling period Ts. A coordinate storage unit 31 stores the coordinates of the pressure points of the resistance film type touch panel 7 acquired by the coordinate acquisition unit 29. A coordinate determination unit 33, from among the coordinates of the pressure points stored in the coordinate storage unit 31, when the coordinates of the resistance film type touch panel 7 when not being pressed is zero coordinates, takes a maximum value as the coordinates of the pressure point. The coordinate determination unit 33, when the coordinates of the resistance film type touch panel 7 when not being pressed is the maximum value, takes a minimum value as the coordinates of the pressure point. |
