Abstract

A method and an electronic device for gesture recognition are provided. The method is applied to an electronic device, which displays at least one object on a touch screen. Wherein the object has two states, one of which is a selected state and the other is an unselected state. The method includes: detecting a first touch point and a second touch point on the touch screen; when the first touch point and the second touch point are on the touch screen simultaneously, and the first touch point corresponds to at least one object, and the second touch point corresponds to at least another object, entering a multi mode. Wherein the at least one object corresponding to the first touch point and the at least one object corresponding to the second touch point are set to the selected state. It can simplify user operations by using this method.

Claims

1. A method of gesture recognition for an electronic device displaying at least one object on a touch screen, wherein, the object has two states, a selected state and an unselected state, the method comprises:

detecting a first touch point and a second touch point on the touch screen;

entering multi-select mode when the first touch point and the second touch point are simultaneously on the touch screen, with the first touch point corresponding to at least one object and the second touch point corresponding to at least one object;

wherein, the at least one object corresponding to the first touch point and the at least one object corresponding to the second touch point are set to the selected state.

2. The method of claim 1, wherein, the at least one object corresponding to the first touch point and the second touch point are set to the selected state as follows:

adding the at least one object corresponding to the first touch point and the second touch point to a multi-select list, and the multi-select list is configured for storing objects in the selected state.

3. The method of claim 1, wherein, the first touch point corresponding to at least one object and the second touch point corresponding to at least one object comprises:

the first touch point and the second touch point correspond to a first object;

or,

the first touch point corresponds to a first object and the second touch point corresponds to a second object;

or,

the first touch point corresponds to a first object, a second object is located inside a first region formed by a closed track with the second touch point as the end-point thereof;

or,

the first object is located inside a second region, and the second region is formed by a closed track with the first touch point as a end-point thereof, the second object is located inside a first region, the first region formed by a closed track with the second touch point as the end-point thereof.

4. The method of claim 3, wherein, if the first touch point and the second touch point correspond to a first object, the method further comprises:

exiting multi-select mode when only one touch point is detected on the touch screen, or when two touch points not corresponding to any object are detected;

if the first touch point corresponds to a first object and the second touch point corresponds to a second object, or if the first touch point corresponds to a first object and a second object is located inside a first region, or if a first object is located inside a second region and a second object is located inside a first region, the method further comprises;

exiting multi-select mode when a third touch point not corresponding to any object is detected on the touch screen.

5. The method of claim 1, wherein, after entering multi-select mode, the method further comprises:

after a third object is detected to be selected, setting the state of the third object to the selected state if the third object was in the unselected state before it was selected.

6. The method of claim 5, wherein, setting the state of the third object to the selected state after the third object is detected to be selected comprises:

detecting a fourth touch point and a fifth touch point simultaneously on the touch screen;

detecting a fourth track formed by the motion of the fourth touch point on the touch screen, and detecting a fifth track formed by the motion of the fifth touch point on the touch screen;

setting the state of the third object to the selected state when the third object is located inside a region formed by the fourth track and the fifth track.

7. The method of claim 6, wherein, the method further comprises:

acquiring the initial position of the third object;

acquiring the target position of the third object according to the fourth track and the fifth track;

moving the third object from the initial position to the target position.

8. An electronic device, displaying at least one object on a touch screen thereof, wherein, the object has two states:

a selected state and an unselected state, the electronic device comprises;

a first detection unit, configured for detecting a first touch point and a second touch point on the touch screen;

a start unit, configured for entering multi-select mode when the first touch point and the second touch point are simultaneously on the touch screen, with the first touch point corresponding to at least one object and the second touch point corresponding to at least one object;

wherein, the at least one object corresponding to the first touch point and the second touch point are set to the selected state.

9. The electronic device of claim 8, wherein, the electronic device further comprises:

a storage unit, configured for storing a multi-select list for storing objects in the selected state;

a processing unit, configured for adding the checked objects to the multi-select list.

10. The electronic device of claim 8, wherein, the electronic device further comprises:

a second detection unit, configured for detecting a fourth touch point and a fifth touch point simultaneously on the touch screen;

a third detection unit, configured for detecting a fourth track formed by the motion of the fourth touch point on the touch screen, and detecting a fifth track formed by the motion of the fifth touch point on the touch screen;

a setting unit, configured for setting the state of the third object to the selected state when the third object is located inside a region formed by a fourth track and a fifth track.

11. The electronic device of claim 10, wherein, the electronic device further comprises:

a first acquisition unit, configured for acquiring the initial position of the third object;

a second acquisition unit, configured for acquiring the target position of the third object according to the fourth track and the fifth track;

a displacement unit, configured for moving the third object from a initial position to the target position.
