Abstract textA device is provided, which uses a positioning system, to determine a first geographic location, while the device is located at the first geographic location. Information concerning the first geographic location may be stored in a computer memory. The device may be moved from the first geographic location to a second geographic location which is substantially different from the first geographic location. The device may be used to determine the second geographic location, while the device is located at the second geographic location. Information concerning the second geographic location may be stored in a computer memory. Directions from the second geographic location to the first geographic location may be provided by the device to a user. The directions may be displayed on a computer monitor or provided orally by use of a voice system. |
