ABSTRACT:
The present invention is directed to an electronic system and method for managing location, calendar, and event information. The system comprises at least two hand portable electronic devices, each having a display device to display personal profile, location, and event information, and means for processing, storing, and wirelessly communicating data. A software program running in the electronic device can receive local and remote input data; store, process, and update personal profile, event, time, and location information; and convert location information into coordinates of a graphic map display. The system additionally includes at least one earth orbiting satellite device using remote sensing technology to determine the location coordinates of the electronic device. The electronic devices receive synchronization messages broadcast by the satellite device, causing the software program to update the personal profile, event, time, and location information stored in each hand portable electronic device.
