Abstract

The present disclosure relates to a method and an apparatus for controlling a smart device. The method includes: when a first hand gesture is detected, preparing to switch a control relationship according to the first hand gesture and a first mapping relationship, the first mapping relationship including a corresponding relationship between hand gestures and respective control functions; when a second hand gesture is detected, determining a target controlled device according to the second hand gesture and a second mapping relationship, the second mapping relationship including a corresponding relationship between hand gestures and locations of respective controlled devices; establishing a first control relationship with the target controlled device; acquiring a third hand gesture; and controlling, according to the third hand gesture and the first mapping relationship, the target controlled device to perform an operation corresponding to the third hand gesture.

Claims

1. A method for use in a controlling device, comprising:

when a first hand gesture is detected, preparing to switch a control relationship according to the first hand gesture and a first mapping relationship, the first mapping relationship including a corresponding relationship between hand gestures and respective control functions;

when a second hand gesture is detected, determining a target controlled device according to the second hand gesture and a second mapping relationship, the second mapping relationship including a corresponding relationship between hand gestures and locations of respective controlled devices;

establishing a first control relationship with the target controlled device;

acquiring a third hand gesture; and

controlling, according to the third hand gesture and the first mapping relationship, the target controlled device to perform an operation corresponding to the third hand gesture.

2. The method according to claim 1, further comprising:

acquiring a first positioning straight line and a second positioning straight line, each of the first positioning straight line and the second positioning straight line being an extension line of a direction pointed by a finger of a user when the user respectively points to a controlled device at a first location and a second location;

determining a location of the controlled device according to an intersection point of the first positioning straight line and the second positioning straight line; and

establishing the second mapping relationship between a hand gesture and the location of the controlled device.

3. The method according to claim 1, further comprising:

establishing the first mapping relationship between a hand gesture and a control function, wherein the hand gesture is used to control the control function in different controlled devices.

4. The method according to claim 1, wherein

the first hand gesture and the second hand gesture are performed by two hands, respectively;

wherein, when the second hand gesture is detected, the determining of the target controlled device according to the second hand gesture and the second mapping relationship further comprises;

when the first hand gesture and the second hand gesture are detected approximately at the same time, determining the target controlled device according to the second hand gesture and the second mapping relationship.

5. The method according to claim 1, wherein

the first hand gesture and the second hand gesture are performed by the same hand;

wherein, when the second hand gesture is detected, the determining of the target controlled device according to the second hand gesture and the second mapping relationship further comprises;

when the detection of the second hand gesture and the detection of the first hand gesture are separated by a predetermined amount of time, determining the target controlled device according to the second hand gesture and the second mapping relationship.

6. The method according to claim 1, further comprising:

releasing the first control relationship with the target controlled device; and

establishing a second control relationship with a second controlled device, the second controlled device being controlled by the controlling device before the first hand gesture is detected.

7. A controlling device, comprising:

one or more processors; and

a memory for storing instructions executable by the one or more processors;

wherein the one or more processors are configured to;

when a first hand gesture is detected, prepare to switch a control relationship according to the first hand gesture and a first mapping relationship, the first mapping relationship including a corresponding relationship between hand gestures and respective control functions;

when a second hand gesture is detected, determine a target controlled device according to the second hand gesture and a second mapping relationship, the second mapping relationship including a corresponding relationship between hand gestures and locations of respective controlled devices;

establish a first control relationship with the target controlled device;

acquire a third hand gesture; and

control, according to the third hand gesture and the first mapping relationship, the target controlled device to perform an operation corresponding to the third hand gesture.

8. The controlling device according to claim 7, wherein the one or more processors are further configured to:

acquire a first positioning straight line and a second positioning straight line, each of the first positioning straight line and the second positioning straight line being an extension line of a direction pointed by a finger of a user when the user respectively points to a controlled device at a first location and a second location;

determine a location of the controlled device according to an intersection point of the first positioning straight line and the second positioning straight line; and

establish the second mapping relationship between a hand gesture and the location of the controlled device.

9. The controlling device according to claim 7, wherein the one or more processors are further configured to:

establish the first mapping relationship between a hand gesture and a control function, wherein the hand gesture is used to control the control function in different controlled devices.

10. The controlling device according to claim 7, wherein

the first hand gesture and the second hand gesture are performed by two hands respectively;

wherein the one or more processors are further configured to;

when the first hand gesture and the second hand gesture are detected approximately at the same time, determine the target controlled device according to the second hand gesture and the second mapping relationship.

11. The controlling device according to claim 7, wherein

the first hand gesture and the second hand gesture are performed by the same hand;

wherein the one or more processors are configured to;

when the detection of the second hand gesture and the detection of the first hand gesture are separated by a predetermined amount of time, determine the target controlled device according to the second hand gesture and the second mapping relationship.

12. The controlling device according to claim 7, wherein the one or more processors are further configured to:

release the first control relationship with the target controlled device; and

establish a second control relationship with a second controlled device, the second controlled device being controlled by the controlling device before the first hand gesture is detected.

13. A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a controlling device, cause the controlling device to perform:

when a first hand gesture is detected, preparing to switch a control relationship according to the first hand gesture and a first mapping relationship, the first mapping relationship including a corresponding relationship between hand gestures and respective control functions;

when a second hand gesture is detected, determining a target controlled device according to the second hand gesture and a second mapping relationship, the second mapping relationship including a corresponding relationship between hand gestures and locations of respective controlled devices;

establishing a first control relationship with the target controlled device;

acquiring a third hand gesture; and

controlling, according to the third hand gesture and the first mapping relationship, the target controlled device to perform an operation corresponding to the third hand gesture.
