Abstract

An input device (101) according to the present invention includes a touch sensor (104) that detects contact, a display unit (103), a pressure detection unit (106) that detects pressure on the touch sensor (104), a memory unit (105) that stores indication information indicating existence of notification information, and a control unit (108) that controls the display unit (103) to display the indication information stored in the memory unit (105) when data based on pressure on the touch sensor (104) becomes equal to or greater than a threshold, thereby displays indication information in accordance with a user'"'"'s desire.

Claims

1. An input device comprising:

a touch sensor configured to detect contact;

a display unit;

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

a memory unit configured to store indication information indicating existence of notification information; and

a control unit configured to control the display unit to display the indication information stored in the memory unit when data based on pressure on the touch sensor becomes equal to or greater than a threshold.

2. The input device according to claim 1, further comprising a tactile sensation providing unit configured to provide a tactile sensation to a contacting object in contact with the touch sensor, wherein

when the data based on pressure on the touch sensor becomes equal to or greater than the threshold, the control unit controls the tactile sensation providing unit to provide the tactile sensation to the contacting object in contact with the touch sensor.

3. The input device according to claim 1, wherein when a position with respect to the touch sensor is a predetermined position, the control unit controls the display unit to display the indication information.

4. The input device according to claim 1, wherein when the display unit is displaying the indication information, and the touch sensor detects contact at a position corresponding to the indication information, the control unit controls the display unit to display notification information corresponding to the indication information.

5. The input device according to claim 1, wherein

the control unit

sets, when a plurality of types of indication information exist, a plurality of thresholds corresponding to the types of indication information, and

when the data based on pressure on the touch sensor becomes equal to or greater than any one of the plurality of thresholds, controls the display unit to display the indication information corresponding to the one of the plurality of thresholds.

6. The input device according to claim 5, wherein

the plurality of types of indication information include first indication information and second indication information, and

the control unit

sets a first threshold corresponding to the first indication information to be a value smaller than a second threshold corresponding to the second indication information, and

when the first indication information is being displayed on the display unit, and the data based on pressure on the touch sensor becomes equal to or greater than the second threshold, controls the display unit to display the second indication information together with the first indication information.

7. The input device according to claim 5, wherein

the plurality of types of indication information include first indication information and second indication information, and

the control unit

sets a first threshold corresponding to the first indication information to be a value smaller than a second threshold corresponding to the second indication information, and

when the first indication information is being displayed on the display unit, and the data based on pressure on the touch sensor becomes equal to or greater than the second threshold, controls the control unit to display the second indication information instead of the first indication information.

8. The input device according to claim 1, wherein

when the contact on the touch sensor satisfies a predetermined trajectory condition while the indication information is being displayed on the display unit, the control unit controls the display unit to hide display of the indication information being displayed on the display unit.

9. The input device according to claim 8, wherein

the control unit sets a deletion threshold larger than the threshold and, when the contact on the touch sensor satisfies the predetermined trajectory condition while the data based on pressure on the touch sensor is equal to or greater than the deletion threshold, controls the display unit to hide display of the indication information.

10. The input device according to claim 5, wherein

when the contact on the touch sensor satisfies a predetermined trajectory condition while the indication information is being displayed on the display unit, the control unit controls the display unit to hide display of the indication information being displayed on the display unit.

11. The input device according to claim 10, wherein

the control unit sets a deletion maximum threshold larger than any other threshold and, when the contact on the touch sensor satisfies the predetermined trajectory condition while the data based on pressure on the touch sensor is equal to or greater than the deletion maximum threshold, controls the display unit to hide display of the indication information being displayed on the display unit.

12. The input device according to claim 1, wherein

when the data based on pressure on the touch sensor becomes less than the threshold while the display unit is displaying a standby screen, the control unit causes the display unit to display a menu screen instead of the standby screen.
