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 temporary position-sharing relationship between it and a second device, the server facilitates symmetrical position sharing between the two devices. While the relationship is active, the server can receive updated position data from one or both devices, and if necessary calculate or recalculate a path based on the updated data. The server can also alert one of the devices should the other move too close to or too far from a specified location.

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.

Abstract: A system for exchanging GPS or other position data between wireless 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 and a TalkControl application. The Buddy Watch application communicates with the GPS receiver and other wireless devices operated by buddies registered in the users phone as part of buddy groups or individually. GPS position data and historical GPS position data can be exchanged between cell phones of buddies and instant buddies such as tow truck drivers via a buddy watch server. Emergency monitoring services can be set up with notifications to programmable individuals in case an individual does not respond. Positions and tracks can be displayed. Target locations can be identified and annotated with text, voice or photo notes, photos, and the locations of buddies.
