Abstract

An electronic device includes a tactile sensation providing unit 30 configured to provide a tactile sensation to a contact object being in contact with a panel 10 and a controller 50 configured to control the tactile sensation providing unit 30 based on an amount of change of data based on press to the panel 10.

Claims

1. An electronic device, comprising:

a tactile sensation providing unit configured to provide a tactile sensation to a contact object being in contact with a panel; and

a controller configured to control the tactile sensation providing unit on the basis of an amount of change of voltage based on press to the panel in comparison with a threshold, wherein the threshold is changed after the tactile sensation providing unit provides the tactile sensation according to a position of contact of the contact object to the panel.

2. An electronic device, comprising:

a tactile sensation providing unit configured to provide a tactile sensation to a contact object being in contact with a panel; and

a controller configured to control the tactile sensation providing unit on the basis of an amount of change of data based on press to the panel in comparison with a threshold, wherein the threshold is changed after the tactile sensation providing unit provides the tactile sensation,

wherein the controller controls the tactile sensation providing unit based on a temporal amount of change of the data and a threshold of amount of change.

6. The electronic device according to claim 2, wherein the controller controls the tactile sensation providing unit based further on the data and a data threshold corresponding to the data.

3. An electronic device, comprising:

a tactile sensation providing unit configured to provide a tactile sensation to a contact object being in contact with a panel; and

a controller configured to control the tactile sensation providing unit on the basis of an amount of change of data based on press to the panel,

wherein the controller calculates a vector indicating the temporal amount of change of the data and a polarity of the amount of change, and based on the vector and a threshold vector, controls the tactile sensation providing unit.

4. The electronic device according to claim 3, wherein the threshold vector has a press threshold vector in which the vector corresponds to a plus direction vector indicating an increase in the amount of change and a release threshold vector in which the vector corresponds to a minus direction vector indicating a decrease in the amount of change.

5. The electronic device according to claim 4, wherein an absolute value of the press threshold vector is larger than an absolute value of the release threshold vector.

7. A control method of an electronic device configured to control a tactile sensation providing unit that provides a tactile sensation to a contact object being in contact with a panel by a controller, the method comprising:

controlling the tactile sensation providing unit based on an amount of change of voltage based on press to the panel in comparison with a threshold, wherein the threshold is changed after the tactile sensation providing unit provides the tactile sensation according to a position of contact of the contact object to the panel.

8. An electronic device, comprising:

a tactile sensation providing unit configured to provide a tactile sensation to a contact object being in contact with a panel; and

a controller configured to control the tactile sensation providing unit based on an amount of change of data based on press to the panel and a threshold of amount of change, wherein

after the tactile sensation providing unit provides a tactile sensation, the controller changes the threshold of amount of change.

9. The electronic device according to claim 8, wherein the controller decreases, after the tactile sensation providing unit provides a tactile sensation, the threshold of amount of change with time.

10. The electronic device according to claim 8, wherein the controller increases, after the tactile sensation providing unit provides a tactile sensation, the threshold of amount of change with time.

11. The electronic device according to claim 8, wherein the controller changes, after the tactile sensation providing unit provides a tactile sensation, the threshold of amount of change depending on a position of contact of the contact object to the panel.

12. A control method of an electronic device configured to control a tactile sensation providing unit that provides a tactile sensation to a contact object being in contact with a panel based on an amount of change of data based on press to the panel and a threshold of amount of change, including a step of

after the tactile sensation providing unit provides a tactile sensation, changing the threshold of amount of change.

13. An electronic device comprising:

a tactile sensation providing unit configured to provide a tactile sensation to a contact object being in contact with a panel; and

a controller configured to control the tactile sensation providing unit based on an amount of change of data based on press to the panel and a threshold of amount of change, wherein

the controller changes, after the tactile sensation providing unit provides a tactile sensation, the threshold of amount of change based on a maximum value of the data based on press to the panel.

14. A control method of an electronic device configured to control a tactile sensation providing unit that provides a tactile sensation to a contact object being in contact with a panel based on an amount of change of data based on press to the panel and a threshold of amount of change, including a step of;

after the tactile sensation providing unit provides a tactile sensation, changing the threshold of amount of change based on a maximum value of the data based on press to the panel.
