Abstract

A system, device and method for identifying, within a local area, a location of an electronic device, such as a mobile telephone, includes determining a signal characteristic of a wireless communication from one or more wireless devices in the local area to the electronic device, wherein determining is performed by the electronic device. Then, based on a comparison of the determined signal characteristic from the one or more wireless devices to a plurality of reference signal characteristics the location of the electronic device in the local area is determined.

Claims

1. A method for identifying a location of an electronic device within a local area, comprising:

storing in the electronic device at least one invalid location;

determining a signal characteristic of a wireless communication from one or more wireless devices in the local area to the electronic device, said determining performed by the electronic device;

determining the location of the electronic device based on a comparison of the determined signal characteristic from the one or more wireless devices to a plurality of reference signal characteristics,

wherein when the determined location of the electronic device is at least partially in the at least one invalid location, changing the determined location to a valid location adjacent to the at least one invalid location.

2. The method of claim 1, wherein determining a signal characteristic includes:

performing a wireless scan of the local area at a plurality of different transmission power levels; and

logging an identifier and a responding signal characteristic of the one or more wireless devices that respond to the scan, and the transmission power level used to perform the scan.

3. The method of claim 2, wherein determining the location includes comparing the logged data for each wireless device to determine which wireless device is closest to the electronic device.

4. The method of claim 2, wherein determining the signal characteristic includes using a transmitter and receiver of the electronic device that are operative to implement at least one of a Bluetooth protocol or a WiFi protocol.

5. The method of claim 1, further comprising controlling at least one electronic appliance in the local area based on the location of the electronic device in the local area.

6. The method of claim 5, wherein controlling at least one electronic appliance includes controlling at least one of a television system, an audio system, a lighting system, a kitchen appliance, a home entertainment system, a personal computer system, a telephone system, or an alarm system.

7. The method of claim 5, wherein the at least one electronic appliances is controlled based on a profile associated with the electronic device and the at least one electronic appliance, said profile including at least one preferred setting for the electronic appliance.

8. The method of claim 7, further comprising prioritizing a plurality of profiles that are usable in the local area, wherein settings of at least one profile can override settings of another profile.

9. The method of claim 5, further comprising controlling the at least one appliance from a user interface on the electronic device.

10. The method of claim 1, further comprising changing, based on the determined location of the electronic device, at least one of a user interface of the electronic device or an operational characteristic of the electronic device.

11. The method of claim 1, further comprising prior to performing the scan, collecting the plurality of reference signal characteristics and storing said reference signal characteristics in memory.

12. A method for using an electronic device to identify a location of the electronic device within a local area, wherein said electronic device includes a short range wireless transceiver, comprising:

storing in the electronic device at least one invalid location;

using the short range transceiver to scan for wireless devices in the local area;

collecting in the electronic device an identifier of each wireless device that responds to the scan, and a signal characteristic of the responding wireless device; and

determining the location of the electronic device in the local area based on the logged data,

wherein when the determined location of the electronic device is at least partially in the at least one invalid location, changing the determined location to a valid location adjacent to the at least one invalid location.

13. The method of claim 12, wherein the scan is performed at at least two different transmission power levels.

14. A portable electronic device, comprising:

a short range wireless transmitter and receiver;

a scanning circuit operative to command the wireless transmitter and receiver to perform a scan for wireless devices in at least part of a local area, and to determine a signal characteristic of a response to the scan;

a logging circuit operative to log in memory of the electronic device an identifier of the responding wireless devices and the corresponding signal characteristic; and

a determination circuit operative to determine a location of the electronic device within the local area based on the logged data,

wherein at least one invalid location is stored in memory of the electronic device, and wherein when the determination circuit determines the location of the electronic device is at least partially in the at least one invalid location, the determination circuit changes the determined location to a valid location adjacent to the at least one invalid location.

15. The electronic device of claim 14, wherein the scanning circuit is further operative to perform the scan a plurality of different transmission power levels, and the logging circuit is operative to log each identifier and signal characteristic with the corresponding transmission power level.

16. The electronic device of claim 14, wherein determination circuit is operative to compare the logged data to reference data to determine which wireless device is closest to the electronic device.

17. The electronic device of claim 14, wherein the wireless transmitter and receiver operate based on a Bluetooth protocol or a WiFi protocol.

18. The electronic device of claim 14, further comprising a control circuit operative to control at least one electronic appliance in the local area based on the determined location of the electronic device in the local area.

19. The electronic device of claim 18, wherein the control circuit is operative to control the at least one electronic appliance based on a profile associated with the electronic device and the at least one electronic appliance, said profile including at least one preferred setting for the electronic appliance.

20. The electronic device of claim 18, further comprising a display for displaying a user interface, wherein the at least one appliance is controllable from the user interface.

21. The electronic device of claim 20, wherein the control circuit is operative to change at least one of the user interface or an operational characteristic of the electronic device based on a location of the electronic device.

22. The electronic device of claim 14, wherein the electronic device is a mobile telephone.

23. A system for controlling the operation of at least one electronic appliance within a local area, comprising:

the portable electronic device configured to determine a location of the electronic device within a local area;

a plurality of wireless devices arranged within the local area;

a controller operatively coupled to the at least one electronic appliance, wherein the electronic device is operative to wirelessly provide the location of the electronic device within the local area to the controller, and the controller is operative to control the operation of the at least one electronic appliance based on the location of the electronic device in the local area,

wherein at least one invalid location is stored in memory of the electronic device, and wherein when the electronic device determines the location of the electronic device is at least partially in the at least one invalid location, the electronic device changes the determined location to a valid location adjacent to the at least one invalid location.

24. The system of claim 23, wherein the at least one electronic appliances is controlled based on a profile associated with the electronic device and the at least one electronic appliance, said profile including at least one preferred setting for the electronic appliance.
