Abstract

Gesture control uses electromagnetic power signatures. A signal is received and a power of the signal is determined. The power is associated to a command, and the command is executed in response to a gesture.

Claims

1. A method of controlling a receiving device, comprising:

determining, by a processor, an electromagnetic power transported by an electromagnetic signal during gesture movement of a remote control;

querying, by the processor, an electronic database for a value associated with the electromagnetic power, the electronic database associating values of electromagnetic powers to possible commands;

retrieving, by the processor, a command of the possible commands from the electronic database, the command electronically associated with the value associated with the electromagnetic power transported by the electromagnetic signal; and

executing, by the processor, the command to control the receiving device.

2. The method of claim 1, further comprising storing the electronic database in a memory of the receiving device.

3. The method of claim 1, further comprising measuring the electromagnetic power.

4. The method of claim 1, further comprising using the Poynting vector to determine the electromagnetic power.

5. The method of claim 1, further comprising determining a change in the electromagnetic power.

6. The method of claim 1, further comprising determining a change over time in the electromagnetic power.

7. The method of claim 1, further comprising preloading an electromagnetic power signature.

8. The method of claim 7, further comprising preloading the command that corresponds to the electromagnetic power signature.

9. A system, comprising:

a processor; and

a memory storing code that when executed causes the processor to perform operations, the operations comprising;

receiving an electromagnetic signal transmitted during movement of a remote control;

determining a value of an electromagnetic power associated with the electromagnetic signal;

querying an electronic database for the value of the electromagnetic power, the electronic database having electronic associations between values of electromagnetic powers and possible commands to identify and to retrieve a command electronically associated with the value of the electromagnetic power; and

executing the command in response to the electromagnetic signal transmitted during the movement of the remote control.

10. The system of claim 9, wherein the operations further comprise storing the electronic database.

11. The system of claim 9, wherein the operations further comprise measuring the electromagnetic power.

12. The system of claim 9, wherein the operations further comprise using the Poynting vector to determine the electromagnetic power.

13. The system of claim 9, wherein the operations further comprise determining a change in the electromagnetic power.

14. The system of claim 9, wherein the operations further comprise determining a change over time in the electromagnetic power.

15. The system of claim 9, wherein the operations further comprise preloading an electromagnetic power signature.

16. The system of claim 15, wherein the operations further comprise preloading the command that corresponds to the electromagnetic power signature.

18. The memory device of claim 14, wherein the operations further comprise measuring the electromagnetic power.

19. The memory device of claim 14, wherein the operations further comprise preloading the command that corresponds to the value of the electromagnetic power.

17. A memory device storing code which when executed causes a processor to perform operations, the operations comprising:

receiving an electromagnetic signal transmitted during a gesture movement of a mobile device;

determining a value of an electromagnetic power associated with the electromagnetic signal;

querying an electronic database for the value of the electromagnetic power, the electronic database having electronic associations between values of electromagnetic powers and possible commands to identify and to retrieve a command electronically associated with the value of the electromagnetic power; and

executing the command in response to the electromagnetic signal transmitted during the gesture movement of the mobile device.
