Abstract

A terminal device including a touchpad and at least one processor is provided. The touchpad includes a reception module configured to, when the operating state is a normal mode, receive a touch on a first region in a detection region of the touchpad, and when the operating state is a power saving mode, only receive a touch on a second region which is a partial region of the first region. The at least one processor is configured to, when the operating state is the power saving mode, transfer the operating state from the power saving mode to the normal mode in response to receiving the touch on the second region by the touchpad when the operating state is the power saving mode.

First claim

1 . A terminal device comprising a touchpad and at least one processor, and having an operating state including a first state and a second state where power consumption is smaller than in the first state,
the touchpad being configured to, when the operating state is the first state, receive a touch on a first region in a detection region of the touchpad, and when the operating state is the second state, only receive a touch on a second region which is a partial region of the first region, the at least one processor being configured to, when the operating state is the second state, transfer the operating state from the second state to the first state in response to receiving the touch on the second region by the touchpad when the operating state is the second state.

2 . The terminal device according to claim 1 , further comprising a memory configured to hold gesture information indicating a gesture on the detection region, wherein
the touchpad is configured to detect a position of the received touch, and the at least one processor is configured to, when the operating state is the second state, determine whether or not to transfer the operating state from the second state to the first state by checking the position detected by the touchpad against the gesture information held by the memory, and transfer the operating state from the second state to the first state depending on a determination result.

3 . The terminal device according to claim 1 , wherein
the operating state further includes a third state where power consumption is larger than in the second state, the touchpad is configured to, when the operating state is the third state, only receive a touch on a third region in the detection region, the touchpad is further configured to detect a position of the received touch, the memory holds gesture information indicating a gesture on the detection region, wherein the at least one processor is configured to transfer the operating state from the second state to the first state via the third state, in response to receiving the touch on the second region by the touchpad when the operating state is the second state, transfer the operating state from the second state to the third state, and when the operating state is the third state, determine whether or not to transfer the operating state from the third state to the first state by checking the position detected by the touchpad against the gesture information held by the memory, and transfer the operating state from the third state to the first state depending on a determination result.

4 . The terminal device according to claim 1 , wherein the at least one processor is configured to, if the touch has not been received on the first region by the touchpad for a certain period of time when the operating state is the first state, transfer the operating state from the first state to the second state.

5 . The terminal device according to claim 1 , further comprising an input unit different from the touchpad, wherein
the operating state further includes a fourth state where power supply to the touchpad is stopped, and the at least one processor is configured to, if the touch has not been received on the second region by the touchpad for a certain period of time when the operating state is the second state, transfer the operating state from the second state to the fourth state, and if an input has been received by the input unit when the operating state is the fourth state, transfer the operating state from the fourth state to the second state.

6 . The terminal device according to claim 1 , further comprising a display, wherein electric power supplied to the display is larger in the first state than in the second state.

7 . The terminal device according to claim 1 , wherein any of partial regions of the first region can be set as the second region.

8 . A control method for controlling a terminal device including a touchpad and at least one processor, and having an operating state including a first state and a second state where power consumption is smaller than in the first state,
the touchpad being configured to, when the operating state is the first state, receive a touch on a first region in a detection region of the touchpad, the method comprising: only receiving a touch on a second region which is a partial region of the first region when the operating state is the second state; and transferring the operating state from the second state to the first state in response to receiving the touch on the second region by the touchpad when the operating state is the second state.

9 . A terminal device comprising a touchpad and at least one processor, and having an operating state including a first state and a second state where power consumption is smaller than in the first state,
the touchpad being configured to receive a touch on a detection region, the detection region including a first region and a second region which is a partial region of the first region, the at least one processor being configured to, when the operating state is the second state, transfer the operating state from the second state to the first state in response to receiving the touch on the second region by the touchpad when the operating state is the second state.
