Abstract

A touch control method is provided, which includes obtaining a first input operation from a first touch-sensitive area of an electronic device; in response to the first input operation, controlling a second touch-sensitive area of the electronic device to switch from a first state to a second state, the first state is a non-operating state, the second state is an operating state; obtaining a second input operation through the second touch-sensitive area in the second state, a starting position of the second input operation is located within the first touch-sensitive area, an operation of the second input operation in the starting position includes the first input operation; and in response to the second input operation, generating an operation instruction corresponding to the second input operation.

Claims

1. A touch control method, comprising:

obtaining a first input operation from a first touch-sensitive area of an electronic device;

controlling a second touch-sensitive area of the electronic device to switch from a first state to a second state, in response to the first input operation;

the first state being a non-operating state, the second state being an operating state;

obtaining a second input operation through the second touch-sensitive area in the second state;

a starting position of the second input operation being located within the first touch-sensitive area, and an operation of the second input operation in the starting position comprising the first input operation; and

generating an operation instruction corresponding to the second input operation, in response to the second input operation.

2. The touch control method as claimed in claim 1, wherein

obtaining the first input operation from the first touch-sensitive area of the electronic device comprises when a first portion of a touch sensing array of a touch sensor of the electronic device is in an operating state and a second portion thereof is in the first state, obtaining the first input operation through the first portion of the touch sensing array of the touch sensor in the operating state;

the first touch-sensitive area and the second touch-sensitive area are corresponding to the touch sensing array of the touch sensor, the first touch-sensitive area corresponding to the first portion of the touch sensing array, the second touch-sensitive area corresponding to the second portion of the touch sensing array; and

controlling the second touch-sensitive area of the electronic device to switch from the first state to the second state comprises controlling the second portion of the touch sensing array of the touch sensor to switch from the first state to the second state.

3. The touch control method as claimed in claim 1, wherein:

obtaining the first input operation from the first touch-sensitive area of the electronic device comprises when a first sensor of the electronic device is in an operating state and the touch sensor of the electronic device is in the first state, obtaining the first input operation by the first sensor;

the first touch-sensitive area corresponding to a sensitive area of the first sensor, and the second touch-sensitive area corresponding to a sensitive area of the touch sensor; and

controlling the second touch-sensitive area of the electronic device to switch from the first state to the second state comprises controlling the touch sensor to switch from the first state to the second state, and controlling the first sensor to switch from the operating state to the non-operating state.

4. The touch control method as claimed in claim 2, wherein the first input operation and the second input operation are different input portions of a single input operation.

5. The touch control method as claimed in claim 4, wherein the first touch-sensitive area is an area first contacted by an operator when inputting the single input operation.

6. The touch control method as claimed in claim 5, wherein:

generating the operation instruction corresponding to the second input operation comprises;

generating a movement command for moving a cursor on a display screen of the electronic device in real time according to an operation trajectory of the second input operation; and

controlling movement of the cursor on the display screen based on the movement command.

7. An electronic device, comprising:

a housing having a touch-sensitive area for touch input; and

a processor configured to;

obtain a first input operation from a first touch-sensitive area of the touch-sensitive area;

control a second touch-sensitive area of the touch-sensitive area to switch from a first state to a second state, in response to the first input operation;

obtain a second input operation through the second touch-sensitive area in the second state; and

generate an operation instruction corresponding to the second input operation, in response to the second input operation;

wherein a starting position of the second input operation is located within the first touch-sensitive area, an operation of the second input operation in the starting position comprises the first input operation and, the first state is a non-operating state, and the second state is an operating state.

8. The electronic device as claimed in claim 7, further comprising:

a first touch sensor having a touch sensing array;

wherein the touch sensing array is corresponding to the touch-sensitive area of the housing;

the first touch-sensitive area is corresponding to a first portion of the touch sensing array, and the second touch-sensitive area is corresponding to a second portion of the touch sensing array;

wherein the processor is coupled with the first touch sensor, the processor is further configured to;

obtain the first input operation through the first portion of the touch sensing array of the first touch sensor, when the first portion of the touch sensing array is in an operating state and the second portion thereof is in the first state; and

control the second portion of the touch sensing array to switch from the first state to the second state in response to the first input operation.

9. The electronic device as claimed in claim 7, further comprising:

a first sensor having a sensing area corresponding to the first touch-sensitive area;

a second touch sensor having a sensing area corresponding to the second touch-sensitive area;

wherein the processor is coupled with the first sensor and the second touch sensor, the processor is further configured to;

obtain the first input operation by the first sensor, when the first sensor is in an operating state and the second touch sensor is in the first state;

control the second touch sensor to switch from the first state to the second state; and

control the first sensor to switch from the operating state to the non-operating state.

10. The electronic device as claimed in claim 8, wherein the second touch-sensitive area surrounds the first touch-sensitive area.

11. The electronic device as claimed in claim 10, further comprising a keyboard having a keyboard input area, the keyboard input area and the touch-sensitive area being located on a same surface of the housing.

12. The electronic device as claimed in claim 11, wherein the first touch-sensitive area of the touch sensitive area is an area not contacted by an input gesture during inputting through the keyboard input area.
