Abstract

A method of tracking a lead mobile device entails receiving tracking data that includes a current location for both the lead mobile device and at least one other mobile device that is also tracking the lead device. The method also entails displaying the current locations of the lead device and of the at least one other mobile device that is also receiving the tracking data. A related method shares tracking data with other mobile devices by activating a communication application, communicating with a plurality of other mobile devices via the communication application, and receiving user input to cause the mobile device to transmit tracking data to the plurality of other mobile devices.

Claims

1. A method of tracking a lead mobile device, the method comprising:

receiving tracking data that includes a current location for both the lead mobile device and at least one other mobile device that is also tracking the lead device; and

displaying the current locations of the lead device and of the at least one other mobile device that is also receiving the tracking data.

2. The method as claimed in claim 1 wherein displaying the tracking data comprises graphically displaying on a map the current locations of the lead mobile device and of other mobile devices that are tracking the lead device.

3. The method as claimed in claim 2 wherein displaying the current locations of the lead mobile device and of other mobile devices comprises visually distinguishing the lead mobile device from the other mobile devices and also visually distinguishing a user device from other mobile devices that are also tracking the lead device.

4. The method as claimed in claim 1 further comprising receiving user input to select a new mobile device as the lead mobile device.

5. The method as claimed in claim 1 wherein receiving tracking data is triggered when a short-range wireless proximity detector loses a connection with the lead device.

6. The method as claimed in claim 1 wherein the tracking data further includes one or more of speed, heading and path.

7. A method of sharing tracking data on a mobile device with other mobile devices, the method comprising:

activating a communication application;

receiving user input to cause the mobile device to transmit tracking data to a plurality of other mobile devices; and

communicating with the plurality of other mobile devices via the communication application.

8. The method as claimed in claim 7 wherein the tracking data comprises one or more of a current location, speed, path and heading.

9. The method as claimed in claim 7 wherein the communication application is an e-mail application.

10. The method as claimed in claim 7 wherein the communication application is an instant messaging application.

11. The method as claimed in claim 7 wherein the communication is a social networking application.

12. The method as claimed in claim 7 further comprising temporarily deactivating tracking when a short-range wireless proximity detector trigger regains a connection with the device.

13. The method as claimed in claim 7 further comprising displaying a map showing a current location of the mobile device that is transmitting the tracking data as well as current locations of the plurality of other mobile devices.

14. A mobile device for tracking both a lead device and at least one other following device that is also tracking the lead device, the mobile device comprising:

a processor operable to control operation of the mobile device;

a positioning system operatively coupled to the processor to determine a current location of the mobile device;

a radio-frequency transceiver operatively coupled to the processor to receive tracking data that includes current locations of a lead device and of the at least one other following device;

a memory operatively coupled to the processor to store the current locations of the mobile device, the lead device and the at least one other following device; and

a display screen operatively coupled to the processor to display the current locations of the mobile device, the lead device, and the at least one other following device.

15. The mobile device as claimed in claim 14 wherein the display screen graphically displays a map depicting the current locations of the mobile device, the lead device and the following devices that are tracking the lead device, the current locations being represented by icons that visually distinguish the lead device from the following devices.

16. The mobile device as claimed in claim 14 comprising a user input device to receive user input to select a new mobile device as the lead device.

17. The mobile device as claimed in claim 14 comprising a short-range wireless proximity detector that triggers tracking when the proximity detector loses a connection with the lead device.

18. A mobile device for sharing tracking data, the mobile device comprising:

a memory storing a communication application;

a processor operatively coupled to the memory to execute the communication application;

a radio-frequency transceiver to communicate with a plurality of other mobile devices via the communication application;

a positioning subsystem operatively coupled to the processor to determine a current location of the mobile device from which the tracking data is generated; and

a user input device operable to receive user input from within the communication application that causes the mobile device to transmit the tracking data to the plurality of other mobile devices.

19. The mobile device as claimed in claim 18 comprising a short-range wireless proximity detector that triggers transmission of the tracking data when the proximity detector loses a connection with a lead device.

20. The mobile device as claimed in claim 18 wherein the tracking data comprises one or more of speed, heading and path data.

21. The mobile device as claimed in claim 18 wherein the communication application is an e-mail application.

22. The mobile device as claimed in claim 18 wherein the communication application is an instant messaging application.

23. The mobile device as claimed in claim 18 wherein the communication application is a social networking application.

24. The mobile device as claimed in claim 18 wherein the memory and processor are operable to recognize user input received by the user input device as a command to initiate a conference call involving the mobile device and the plurality of other mobile devices.
