Directional location system for a portable electronic device

1. A method for indicating, on a display of a first portable electronic device, a location of a second portable electronic device, said method comprising:

determining global location coordinates of said first portable electronic device;

receiving global location coordinates of said second portable electronic device, said first portable electronic device being authorized in an authorization process to receive location information of said second portable electronic device;

determining a relative direction from said first portable electronic device to said second portable electronic device;

providing a visual identifier superimposed on a map that is provided on said display to represent said relative direction from said first portable electronic device to said second portable electronic device,

wherein receiving of the global location coordinates of said second portable electronic device occurs continuously and without repeated requests from the first portable electronic device such that said visual identifier is updated continuously every time there is a change in said global location coordinates of said first portable electronic device or said second portable electronic device.

2. A method as claimed in claim 1 , wherein said global location coordinates are sent from said second portable electronic device to said first portable electronic device.

3. A method as claimed in claim 1 , wherein said global location coordinates of said second portable electronic device are manually input into said first portable electronic device.

4. A method as claimed in claim 1 , wherein said global location coordinates of said second portable electronic device are downloaded from a database.

5. A method as claimed in claim 1 , wherein said global location coordinates of said second portable electronic device are downloaded from the internet.

6. A method as claimed in claim 1 , further comprising: providing text on said display to specify a distance between said first portable electronic device and said second portable electronic device.

7. A portable electronic device having a directional location system, said directional location system comprising:

location determining hardware for providing global location coordinates of said portable electronic device;

a destination application for receiving global location coordinates of a second portable electronic device, said portable electronic device being authorized in an authorization process to receive location information of said second portable electronic device;

an electronic compass for determining a relative direction from said portable electronic device to said second portable electronic device;

an arrow application for providing a visual identifier superimposed on a map that is provided on a display of said portable electronic device, said visual identifier representing said relative direction from said portable electronic device to said second portable electronic device,

wherein the receiving of the global location coordinates of said second portable electronic device occurs continuously and without repeated requests from the first portable electronic device such that said visual identifier is updated continuously every time there is a change in said global location coordinates of said first portable electronic device or said second portable electronic device.

8. A portable electronic device as claimed in claim 7 , wherein said device is arranged to receive the global location coordinates of said second portable electronic device from said second portable electronic device.

9. A portable electronic device as claimed in claim 7 , wherein said device is arranged to receive the global location coordinates of said second portable electronic device by manually input into said portable electronic device.

10. A portable electronic device as claimed in claim 7 , wherein said device is arranged to receive the global location coordinates of said destination are downloaded from a database.

11. A portable electronic device as claimed in claim 7 , wherein said device is arranged to receive the global location coordinates of said second portable electronic device by downloaded from the internet.

12. A portable electronic device as claimed in claim 7 , wherein said arrow application further provides text on said display to specify a distance between said first portable electronic device and said second portable electronic device.

13. A method as claimed in claim 1 , wherein said first portable electronic device specifies said second portable electronic device as a device to track prior to receiving global location coordinates therefrom.

14. A portable electronic device as claimed in claim 7 , wherein said portable electronic device specifies said second portable electronic device as a device to track prior to receiving global location coordinates therefrom.

15. A method as claimed in claim 1 , wherein said visual identifier is updated when there is a change in said global location coordinates of said first portable electronic device and said second portable electronic device.

16. A portable electronic device as claimed in claim 7 , wherein said visual identifier is updated when there is a change in said global location coordinates of said portable electronic device and said second portable electronic device.

17. A method as claimed in claim 1 , wherein said visual identifier is an arrow.

18. A method as claimed in claim 1 , wherein said relative direction from said first portable electronic device to said second portable electronic device is determined using an electronic compass.

19. A portable electronic device as claimed in claim 7 , wherein said arrow application is arranged to provide an arrow as the visual identifier.

20. A method as claimed in claim 1 , wherein the visual identifier is updated every time there is a change in any of the global location coordinates of said first portable electronic device, the global location coordinates of said second portable electronic device, or said relative direction.

21. A portable electronic device as claimed in claim 7 , wherein the visual identifier is updated every time there is a change in any of the global location coordinates of said first portable electronic device, the global location coordinates of said second portable electronic device, or said relative direction.

22. The method as claimed in claim 1 , further comprising downloading the map from a network.

23. The method as claimed in claim 1 , wherein the superimposing of the visual identifier on the map is at the global location coordinates of said first portable electronic device.

24. The method of claim 23 , wherein the global location coordinates of said second portable electronic device are not displayed on the map.
