Abstract

A load control system may include load control devices for controlling an amount of power provided to an electrical load. The load control devices may be capable of controlling the amount of power provided to the electrical load based on control instructions received from a gesture-based control device. The gesture-based control device may identify gestures performed by a user for controlling a load control device and provide control instructions to the load control device based on the identified gestures. The gestures may be identified based on images received from a motion capture device. A gesture may be associated with a scene that includes a configuration of one or more load control devices in a load control system. The user may perform one or more gestures to program the gesture-based control device.

First claim

identify, via generated images, a first gesture performed by a user,
determine the at least one electrical load of a plurality of electrical loads based on the first gesture that is identified in the generated images,
identify, via the generated images, a second gesture performed by the user,
determine control instructions for controlling the at least one electrical load based on the second gesture that is identified in the generated images, wherein the control instructions are capable of controlling the amount of power provided to the at least one electrical load, and
control the amount of power provided to the at least one electrical load based on the control instructions.

2. The control device of claim 1 , further comprising a load control circuit, and wherein the controller is configured to control the amount of power provided to the at least one electrical load via the load control circuit.

3. The control device of claim 1 , wherein the first gesture is identified based on a first coordinate associated with the user's body, and wherein the second gesture is identified based on a second coordinate associated with the user's body.

4. The control device of claim 3 , wherein the first coordinate is associated with a first arm of the user, and wherein the second coordinate is associated with a second arm of the user.

5. The control device of claim 1 , wherein the controller is further configured to:
identify a speed at which the second gesture is performed, and
determine the amount of power provided to the at least one electrical load based on the identified speed.

6. The control device of claim 1 , wherein the controller is further configured to:
identify a distance over which the second gesture is performed, and
determine the amount of power provided to the at least one electrical load based on the identified distance.

7. The control device of claim 1 , wherein the controller is further configured to determine the at least one electrical load based on a vector associated with the first gesture.

8. The control device of claim 1 , wherein the first gesture and the second gesture are identified in different regions of a regional mapping configuration of one or more of the generated images.

9. The control device of claim 1 , further comprising a camera configured to generate the images.

10. A load control system for controlling an amount of power provided to at least one electrical load via at least one load control device, the load control system comprising:

13. The load control system of claim 10 , wherein the gesture-based control device is further configured to:
identify a speed at which the second gesture is performed, and
determine the amount of power provided to the at least one electrical load based on the identified speed.

14. The load control system of claim 10 , wherein the gesture-based control device is further configured to:
identify a distance over which the second gesture is performed, and
determine the amount of power provided to the at least one electrical load based on the identified distance.

15. The load control system of claim 10 , wherein the gesture-based control device is further configured to determine the at least one load control device based on a vector associated with the first gesture.

16. The load control system of claim 10 , wherein the first gesture and the second gesture are identified in different regions of a regional mapping configuration of one or more of the images generated by the motion capture device.

17. A control device for controlling an amount of power provided to at least one electrical load, the control device comprising:
