Abstract
A mobile user device, such as a personal digital assistant (PDA 100), a wireless telephone, a car phone, or any other programmable device that the user generally has with him or her, is equipped with a global positioning system (GPS) receiver (101) and is programmable (102) by the user to alert the user to when he or she arrives with the device at a predetermined location (252), as well as to disclose (101) to the user whatever information (263) the user chose to associate with that location (e.g., a 'to-do' list). The user can program in the geographical coordinates (253) of locations and location names (252), and thereafter refer to the locations by name. The user can also program in a range (254) around each location, so that his or her arrival within that range will trigger the alert for the location.
