Abstract

A tactile sensation providing apparatus includes a touch sensor 11 configured to receive an input, a load detection unit 12 configured to detect a pressure load on a touch face 11a of the touch sensor 11, a tactile sensation providing unit 13 configured to vibrate the touch face 11a, a memory unit 15 configured to store drive signal information for the tactile sensation providing unit 13, and a control unit 16 configured, when the pressure load detected by the load detection unit 12 satisfies a standard for providing a tactile sensation, to retrieve the drive signal information from the memory unit 15 and to control drive of the tactile sensation providing unit 13 based on the drive signal information such that a button depression sensation is provided one time to a pressing object pressing the touch face 11a.

Claims

1. A tactile sensation providing apparatus comprising:

a touch sensor configured to receive an input;

a load detection unit configured to detect a pressure load on a touch face of the touch sensor;

a tactile sensation providing unit configured to vibrate the touch face;

a memory unit configured to store drive signal information for the tactile sensation providing unit; and

a control unit configured, when the pressure load detected by the load detection unit satisfies a standard for providing a tactile sensation, to retrieve the drive signal information from the memory unit and to control drive of the tactile sensation providing unit based on the drive signal information such that a button depression sensation is provided one time to a pressing object pressing the touch face.

2. A control method for a tactile sensation providing apparatus including

a touch sensor configured to receive an input;

a load detection unit configured to detect a pressure load on a touch face of the touch sensor;

a tactile sensation providing unit configured to vibrate the touch face; and

a memory unit configured to store drive signal information for the tactile sensation providing unit, the method comprising;

a step, when the pressure load detected by the load detection unit satisfies a standard for providing a tactile sensation, to retrieve the drive signal information from the memory unit and to control drive of the tactile sensation providing unit based on the drive signal information such that a button depression sensation is provided one time to a pressing object pressing the touch face.
