Abstract

An interactive system and method for navigating a person from a starting point to a destination, using a wireless location determining device and a wireless navigating device. The person sends a request for navigational directions via the wireless location determining device. Using a database that contains the geographic location and a corresponding name of the starting point and the destination, the request is answered and navigational information is sent to the wireless navigating device. The database was previously established by recording the movement of subjects, using a wireless location determining device, as the subjects moved from place to place in their environment. When the number of occurrences of subjects passing by any individual location reached a predetermined threshold, the subjects were prompted to enter a name that described and corresponded to that location. Using the provided navigational information, the person moves from the starting point toward the destination. Optionally, the wireless location determining device periodically sends the current geographic location of the person as he travels. Optionally the wireless location determining device periodically receives additional navigational information in response to the periodically sent information to update the person.
