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, comprising:

receiving, by a processor, an electromagnetic signal generated during gesture movement of a device;

determining, by the processor, an electromagnetic power associated with the electromagnetic signal;

obtaining, by the processor, a value associated with the electromagnetic power determined from the electromagnetic signal;

identifying, by the processor, a command that matches the value associated with the electromagnetic power; and

executing, by the processor, the command in response to the electromagnetic signal generated during the gesture movement of the device.

2. The method of claim 1, wherein the value is obtained from a database.

3. The method of claim 1, further comprising instructing a different device to execute the command.

4. The method of claim 1, wherein the device comprises a mobile device.

5. The method of claim 1, further comprising:

determining an updated electromagnetic power;

obtaining an updated value associated with the updated electromagnetic power.

6. The method of claim 5, further comprising identifying another command that matches the updated value.

7. The method of claim 1, wherein the electromagnetic power is determined according to a plurality of measurements associated with the electromagnetic signal.

8. The method of claim 1, wherein the electromagnetic power is determined according to an electromagnetic power signature.

9. The method of claim 1, wherein the electromagnetic power is determined according to a Poynting vector.

10. A system, comprising:

a processor; and

a memory device that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising;

receiving an electromagnetic signal generated during gesture movement of a device;

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

identifying a command in a table that is associated with the value of the electromagnetic power; and

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

11. The system of claim 10, wherein the operations further comprise storing a plurality of commands in a database.

12. The system of claim 10, wherein the operations further comprise measuring the electromagnetic power.

13. The system of claim 10, wherein the system comprises a communication device.

14. The system of claim 10, wherein the operations further comprise determining the electromagnetic power according to a plurality of measurements associated with the electromagnetic signal.

15. The system of claim 10, wherein the operations further comprise detecting a change in the electromagnetic power and updating the value according to the change.

16. The system of claim 10, wherein the operations further comprise determining the electromagnetic power according to a power signature.

17. The system of claim 10, wherein the electromagnetic signal is generated by a communication device.

18. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, the operations comprising:

detecting a wireless signal generated during gesture movement of a device;

determining a value associated with an energy level of the wireless signal;

detecting a match between the value associated with the energy level and an entry in a table;

obtaining a command associated with the entry in the table; and

executing the command in response to the wireless signal generated during the gesture movement of the device.

19. The machine-readable storage medium of claim 18, wherein the operations further comprise initiating the command.

20. The machine-readable storage medium of claim 18, wherein the wireless signal is transmitted by the device.
