Tactile sensation providing apparatus
First Claim
1. A tactile sensation providing apparatus comprising:
- a touch sensor;
a main control unit configured to process data;
a tactile sensation providing unit comprising a first piezoelectric element configured to vibrate a touch face of the touch sensor based on a signal from the main control unit to provide a first tactile sensation and a second tactile sensation to an operation object on the touch face;
an operation detection unit configured to detect an operation to the touch sensor; and
a tactile sensation provision control unit configured to control drive of the tactile sensation providing unit, whereinthe main control unit outputs a state signal indicating a first operation state in which the main control unit is not busy in taking time for executing data processing or a second operation state in which the main control unit is busy in taking time for executing data processing,the tactile sensation provision control unit, based on the state signal, vibrates the tactile sensation providing unit in a first vibration mode when the operation detection unit detects the operation in the first operation state such that the first tactile sensation is provided to the operation object on the touch face, and vibrates the tactile sensation providing unit in the second vibration mode when the operation detection unit detects the operation in the second operation state such that a second tactile sensation is provided to the operation object,the operation detection unit comprises a second piezoelectric element that does not provide a tactile sensation, wherein the second piezoelectric element detects an operation to the touch sensor, andthe operation detection unit is configured to directly supply the tactile sensation provision control unit with detection information of the operation object detected by the touch sensor or a signal corresponding to the detection information.

Abstract
When an operation to a touch sensor 11 is detected in a first operation state in which a main control unit 16 is not busy with data processing, a tactile sensation provision control unit 14 controls a tactile sensation providing unit 13 to vibrate a touch face 11a in a first vibration mode such that a first tactile sensation is provided to an operation object. On the other hand, when the operation is detected in a second operation state in which the main control unit 16 is busy with data processing, the touch face 11a is vibrated in a second vibration mode such that a second vibration is provided to the operation object. Since different tactile sensations are provided, an operator may recognize whether processing corresponding to the operation may be executed. Thereby, re-inputs are minimized.
