Abstract

A touch sensor includes a sensor and a processor. The sensor detects touch operations on first, second, and third regions of a sensor region disposed along a longitudinal direction of an outer edge portion of a terminal device. The second and third regions are on opposite sides of the first region. The processor identifies the orientation of the terminal device as a first orientation where the sensor region is located at the top or bottom of the terminal device or a second orientation where the sensor region is located at the right or left of the terminal device, and makes a different determination as to whether the first region is depressed based on whether the identified orientation is the first or second orientation, in response to detection of the touch operation on at least one of the second and third regions together with the touch operation on the first region.

Claims

1. A touch sensor, comprising:

a sensor region divided into a first region, a second region, and a third region that are disposed along a longitudinal direction of an outer edge portion of a terminal device, the second region and the third region being positioned on opposite sides of the first region;

a sensor configured to detect touch operations on the first region, the second region, and the third region;

a memory; and

a processor coupled to the memory, and configured to

identify an orientation of the terminal device as a first orientation in which the sensor region is located at a top or a bottom of the terminal device or a second orientation in which the sensor region is located at a right or a left of the terminal device; and

make a different determination as to whether the first region is depressed based on whether the identified orientation of the terminal device is the first orientation or the second orientation, in response to detection of the touch operation on at least one of the second region and the third region together with the touch operation on the first region.

2. The touch sensor as claimed in claim 1, wherein, in response to the detection of the touch operation on the at least one of the second region and the third region together with the touch operation on the first region, the processor is configured to determine that the first region is depressed when the identified orientation of the terminal device is the second orientation, and to determine that the first region is not depressed when the identified orientation of the terminal device is the first orientation.

3. The touch sensor as claimed in claim 2, wherein, in response to detection of the touch operation on the second region and the touch operation on the third region together with the touch operation on the first region, the processor is configured to determine that the first region is not depressed when the identified orientation of the terminal device is the second orientation.

4. A terminal device, comprising:

the touch sensor as set forth in claim 1;

another memory; and

another processor coupled to said another memory, and configured to perform an operation for executing a function correlated to the first region in response to determining, by the processor of the touch sensor, that the first region is depressed.

5. The terminal device as claimed in claim 4, wherein, in response to the detection of the touch operation on the at least one of the second region and the third region together with the touch operation on the first region, the processor of the touch sensor is configured to determine that the first region is depressed when the identified orientation of the terminal device is the second orientation, and to determine that the first region is not depressed when the identified orientation of the terminal device is the first orientation.

6. The terminal device as claimed in claim 5, wherein, in response to detection of the touch operation on the second region and the touch operation on the third region together with the touch operation on the first region, the processor of the touch sensor is configured to determine that the first region is not depressed when the identified orientation of the terminal device is the second orientation.

7. A touch sensor, comprising:

a sensor region divided into a first region, a second region, a third region, a fourth region, and a fifth region that are disposed along a longitudinal direction of an outer edge portion of a terminal device, the second region and the third region being positioned on opposite sides of the first region, the fourth region being positioned between the first region and the second region, the fifth region being positioned between the first region and the third region;

a sensor configured to detect touch operations on the first region, the second region, the third region, the fourth region, and the fifth region;

a memory; and

a processor coupled to the memory, and configured to

identify an orientation of the terminal device as a first orientation in which the sensor region is located at a top or a bottom of the terminal device or a second orientation in which the sensor region is located at a right or a left of the terminal device; and

make a different determination as to whether the first region is depressed based on whether the identified orientation of the terminal device is the first orientation or the second orientation, in response to detection of the touch operation on the fourth region or the fifth region together with the touch operation on the first region.

8. The touch sensor as claimed in claim 7, wherein, in response to the detection of the touch operation on the fourth region or the fifth region together with the touch operation on the first region, the processor is configured to determine that the first region is depressed when the identified orientation of the terminal device is the second orientation, and to determine that the first region is not depressed when the identified orientation of the terminal device is the first orientation.

9. A terminal device, comprising:

the touch sensor as set forth in claim 7;

another memory; and

another processor coupled to said another memory, and configured to perform an operation for executing a function correlated to the first region in response to determining, by the processor of the touch sensor, that the first region is depressed.

10. The terminal device as claimed in claim 9, wherein, in response to the detection of the touch operation on the fourth region or the fifth region together with the touch operation on the first region, the processor of the touch sensor is configured to determine that the first region is depressed when the identified orientation of the terminal device is the second orientation, and to determine that the first region is not depressed when the identified orientation of the terminal device is the first orientation.

11. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a depression detecting process, the depression detecting process comprising:

identifying an orientation of a terminal device as a first orientation in which a sensor region is located at a top or a bottom of the terminal device or a second orientation in which the sensor region is located at a right or a left of the terminal device, the sensor region being divided into a first region, a second region, and a third region that are disposed along a longitudinal direction of an outer edge portion of the terminal device, the second region and the third region being positioned on opposite sides of the first region, wherein touch operations on the first region, the second region, and the third region are detected by a sensor; and
