Abstract

A system for exchanging GPS or other position data between devices for purposes of group activities, child location monitoring, work group coordination, dispatching of employees etc. Cell phones and other wireless devices with GPS receivers have loaded therein a Buddy Watch application that communicates with a remote Buddy Watch Server. The server gets or maintains position data for the wireless devices. When the server receives a request from a first device to set up a position-sharing relationship between it and a second device, the server calculates a path between the devices and transmits the path to each device. One or both users can then approach the other along the path. During this process, the server can receive updated position data from one or both devices, and if necessary recalculate the path based on the updated data.

Claims

1. A method of sharing position data between a first device associated with a first user and a second device associated with a second user, the position data including first position data indicating a first location of the first device and second position data indicating a second location of the second device, the method comprising:

communicating with the first device to authenticate the first device as a subscriber to a location-sharing service;

receiving, from the first device, a request for a token, the token to allow the first device to authorize a position-sharing relationship between the first and second devices;

sending the requested token to the first device, thereby allowing the first device to share the token with the second device;

receiving, from the second device, an assent to share the second position data, the assent including the requested token;

receiving the second position data from the second device;

calculating a path between the first position and the second position, the path including waypoints;

transmitting the path to the first device and the second device;

receiving updated position data from one of the first device and the second device;

recalculating the path based on the updated position data; and

transmitting the recalculated path to the first device and the second device.

2. The method of claim 1, further comprising receiving the first position data from the first device before receiving the second position data.

3. The method of claim 1, further comprising associating the first user with wireless devices of a list of buddies.

4. The method of claim 3, further comprising sending locations of the wireless devices to the first device.

5. The method of claim 1, wherein at least one of the devices is GPS-enabled.

6. The method of claim 5, wherein the GPS-enabled device is a phone.

7. The method of claim 6, further comprising issuing a location update request to the GPS-enabled phone.

8. The method of claim 1, further comprising sending a confirmation to the first device responsive to the assent.

9. The method of claim 1, further comprising automatically terminating the position-sharing relationship.

10. The method of claim 1, further comprising receiving an interval from one of the first device and the second device and automatically terminating the position-sharing relationship after the interval.

11. The method of claim 1, further comprising automatically terminating the position-sharing relationship at a designated time.

12. The method of claim 11, further comprising receiving the designated time from one of the first and second users.

13. The method of claim 1 carried out on a server executing non-transitory computer-readable instructions.

14. The method of claim 1, further comprising publishing the first and second position data to a third user.

15. The method of claim 1, further comprising publishing the first and second position data on a map displayed on the first device, wherein the publishing depicts the first and second users on the map and identifies a buddy relationship between the first and second users.

16. The method of claim 1, further comprising storing information indicative of a relationship between the first user and the second user.

17. The method of claim 16, wherein the relationship is a buddy relationship.

18. The method of claim 1, further comprising storing information designating a fixed or moving target, associating a label with the target, and transmitting the label to at least one of the first and second devices.

19. The method of claim 1, further comprising storing information designating a fixed or moving target, associating a picture with the target, and transmitting the picture to at least one of the first and second devices.

20. The method of claim 1, further comprising storing information designating a fixed or moving target, associating a pointer to a camera file with the target, and transmitting content from the camera file to at least one of the first and second devices.

21. The method of claim 1, further comprising storing information designating a fixed or moving target, associating a message with the target, and transmitting the message to at least one of the first and second devices.

22. The method of claim 1, further comprising relating the first and second devices responsive to the request to establish the position-sharing relationship.

23. A server for sharing position data between first and second devices associated with respective first and second users, the position data including first position data indicating a first location of the first device and second position data indicating a second location of the second device, the server comprising

server-side storage storing a list of people, the list including the first user;

an interface to communicate with the first and second devices, the interface receiving the first and second position data;

wherein the server, via the interface;

sends the requested token to the first device, thereby allowing the first device to share the token with the second device;

receives the requested token and the second position data from the second device;

calculates a path between the first position and the second position, the path including waypoints;

transmits the path to the first device and the second device;

receives updated position data from one of the first device and the second device;

recalculates the path based on the updated position data; and

transmits the recalculated path to the first device and the second device.

24. The server of claim 23, wherein the server receives the first position data from the first device before receiving the second position data.

25. The server of claim 23, further comprising associating, responsive to input from the first user, the first user with buddies.
