20080231507 | METHOD AND SYSTEM FOR NAVIGATING TO A COMMON POINT OF INTEREST BASED ON THE LOCATIONS OF MULTIPLE GPS RECEIVERS - A method of navigating to a common point of interest (POI) based on the locations of multiple global positioning system (GPS) receivers. In a first GPS receiver, an identifier of a second GPS receiver is selected from a list of pre-defined GPS receiver identifiers stored within the first GPS receiver. The first GPS receiver exchanges coordinates with the second GPS receiver. If the location of the second GPS receiver is the POI, the first GPS receiver calculates and displays navigational directions to the location of the second GPS receiver. If a location other than the second GPS receiver is the POI, the first GPS receiver calculates and displays multiple convenient meeting points based on pre-defined preferences. When one of the meeting points is selected, the first GPS receiver sends the coordinates to the other GPS receivers, and the first GPS receiver calculates and displays navigational directions to the meeting point. | 09-25-2008 |
