Abstract

An information processing apparatus includes a sensor; a touch panel; and a processor coupled to the sensor and the touch panel and is configured to control the information processing apparatus, wherein the sensor is configured to transmit an interrupt notification to the touch panel so as to wake up the touch panel when detecting an operation performed upon the sensor, and wherein the touch panel is configured to: determine whether a contact with the touch panel has been detected when being waked up, and transmit an interrupt notification to the processor so as to wake up the processor when it is determined that a contact with the touch panel has not been detected.

Claims

1. An information processing apparatus, comprising:

a sensor;

a touch panel; and

a processor coupled to the sensor and the touch panel and is configured to control the information processing apparatus,

wherein the sensor is configured to transmit an interrupt notification to the touch panel so as to wake up the touch panel when detecting an operation performed upon the sensor, and

wherein the touch panel is configured to;

determine whether a contact with the touch panel has been detected when being waked up, and

transmit an interrupt notification to the processor so as to wake up the processor when it is determined that a contact with the touch panel has not been detected.

2. The information processing apparatus according to claim 1,

wherein the touch panel is configured to be brought into a sleep state when it is determined that a contact with the touch panel has been detected.

3. The information processing apparatus according to claim 1, further comprising

a display that is disposed to overlap the touch panel,

wherein the processor is configured to transmit a display control signal to the display so as to bring the display into a display state, when receiving the interrupt notification used for wake-up of the processor.

4. The information processing apparatus according to claim 1, wherein the sensor is a fingerprint sensor.

5. The information processing apparatus according to claim 4,

wherein the sensor is configured to determine whether a contact with the touch panel has been detected, when detecting a contact with the sensor.

6. The information processing apparatus according to claim 4,

wherein the sensor is configured to determine whether a contact with the touch panel has been detected, when detecting an operation of pressing the sensor.

7. The information processing apparatus according to claim 1,

wherein the sensor is an electrostatic sensor configured to determine whether a contact with the touch panel has been detected, when detecting a contact with the electrostatic sensor.

8. The information processing apparatus according to claim 1,

wherein the sensor is configured to determine that the contact with the touch panel has not been detected, when a contact with the touch panel is not detected within a predetermined period from detection of an operation performed upon the sensor.

9. The information processing apparatus according to claim 1,

wherein the sensor is configured to determine that the contact with the touch panel has not been detected, when a portion of a contact with the touch panel detected within a predetermined period from detection of an operation performed upon the sensor is equal to or less than a threshold value.

10. An information processing apparatus, comprising:

a sensor;

a display;

a touch panel that is disposed to overlap the display; and

a processor configured to control the information processing apparatus,

wherein the sensor is configured to

transmit an interrupt notification to the processor so as to wake up the processor when detecting an operation performed upon the sensor, and

wherein the processor is configured to;

determine whether a contact with the touch panel has been detected when being waked up, and

transmit a display control signal to the display so as to bring the display into a display state when it is determined that a contact with the touch panel has not been detected.

11. An information processing method executed by a touch panel included in an information processing apparatus, the information processing method comprising:

determining whether a contact with the touch panel has been detected when detecting an operation performed upon a sensor; and

transmitting a wake-up signal to a processor for controlling the information processing apparatus so as to wake up the information processing apparatus when it is determined that a contact with the touch panel has not been detected.
