Abstract

Aspects of the present invention include a device including processing circuitry that detects a first user action according to a first signal received from a first sensor while operating in a first mode, the first user action being gripping and lifting up of the device, changes an operation mode from the first mode to a second mode based on the first user action, detects a second user action according to a second signal received from a second sensor while operating the second mode, the second user action being a touch operation, performs an operation based on the second user action, and changes the operation mode from the second mode to a third mode after a predetermined period of time elapses, the second mode consuming more power than the first mode, and the third mode consuming more power than the first mode.

Claims

1. A device, comprising:

processing circuitry configured to;

detect a first user action according to a first signal received from a first sensor while operating in a first mode, the first user action being gripping and lifting up of the device;

change an operation mode from the first mode to a second mode based on the first user action;

detect a second user action according to a second signal received from a second sensor while operating the second mode, the second sensor being a capacitance-type touch sensor, the second user action being a touch operation of a display of the device and the second user action being consistent with a first detection condition associated with the second mode;

perform an operation based on the second user action; and

change the operation mode from the second mode to a third mode after a predetermined period of time elapses without detection of the second user action, wherein

the second mode consumes more power than the first mode, and

the third mode is a power saving mode configured to save power consumed by the second sensor, the third mode consuming more power than the first mode.

2. The device according to claim 1, wherein the second mode is an active mode.

3. The device according to claim 1, wherein the processing circuitry is configured to change the operation mode from the second mode to the first mode after a predetermined period of time elapses without detection of the second user action.

4. The device according to claim 1, wherein the first sensor and the second sensor are different sensors.

5. The device according to claim 1, wherein the first sensor is an acceleration sensor.

6. The device according to claim 5, wherein the acceleration sensor is a piezoelectric-type sensor or a piezo resistance-type sensor.

7. The device according to claim 1, further comprising the first sensor and the second sensor.

8. The device according to claim 1, wherein the second mode consumes more power than the third mode.

9. A non-transitory computer readable medium storing computer executable instructions which, when executed by processing circuitry of a device, cause the device to:

receive a first signal from a first sensor to detect a first user action while operating in a first mode, the first user action being gripping and lifting up of the device;

change an operation mode from the first mode to a second mode based on the first user action;

determine, when a second signal is received from a second sensor and the operation mode is the second mode, that a second user action is performed, the second sensor being a capacitance-type sensor, the second user action being a touch operation of a display of the device and the second user action being consistent with a first detection condition associated with the second mode;

perform an operation based on the second user action; and

change the operation mode from the second mode to a third mode after a predetermined period of time elapses without detection of the second user action, wherein

the second mode consumes more power than the first mode, and

the third mode is a power saving mode configured to save power consumed by the second sensor, the third mode consuming more power than the first mode.

10. The non-transitory computer readable medium according to claim 9, wherein the device is further caused to change the operation mode from the second mode to the first mode after a predetermined period of time elapses without detection of second user action.

12. A method, comprising:

receiving a first signal from a first sensor, of a device, to detect a first user action while operating in a first mode, the first user action being gripping and lifting up of the device;

changing, by processing circuitry of the device, an operation mode from the first mode to a second mode based on the first user action state;

determining, when a second signal is received from a second sensor and the operation mode is the second mode, that a second user action is performed, the second sensor being a capacitance-type sensor, the second user action being a touch operation of a display of the device and the second user action being consistent with a first detection condition associated with the second mode;

performing, by the processing circuitry, an operation based on the second user action; and

changing the operation mode from the second mode to a third mode after a predetermined period of time elapses without detection of the second user action, wherein

the second mode consumes more power than the first mode, and

the third mode is a power saving mode configured to save power consumed by the second sensor, the third mode consuming more power than the first mode.

13. The method according to claim 12, wherein the first sensor is an acceleration sensor.
