Navigation system destination entry
View Patent ↗A system and method for entering a destination into a navigation system, usually a vehicle navigation system, that reduces the cognitive load on the vehicle user over known systems. The method includes contacting the destination by any suitable and available manner, such as by a cell phone provided on or in the vehicle, through the internet, through an ad-hoc network, etc., where information concerning the GPS location of the destination is sent back to the navigation system and is displayed on the navigation system screen. If the destination is accurate, the vehicle driver can select that destination, such as by touching an icon on the screen, which would allow the destination entry process to be performed while the vehicle was moving.
1. A method for entering a destination into a navigation system, said method comprising:
transmitting a message from the navigation system to an object at the destination;
receiving the message by the object at the destination and determining that the message is asking for a signal identifying the destination;
transmitting the signal identifying a location of the object back to the navigation system, where the object has a GPS receiver and the GPS receiver provides the location of the object, and the object is in wireless communications with another device at the destination, the other device provides location data to the object, and the object combines the location data from the other device with data from the GPS receiver in the location of the object that is transmitted back to the navigation system;
displaying the location on a screen, where the screen is part of the navigation system; and
selecting the location as the destination.
2. The method according to claim 1 wherein the object is a cellular telephone and the message are cellular telephone call between the navigation system and the object.
3. The method according to claim 1 wherein transmitting the message from the navigation system to an object includes using a cellular telephone at the navigation system's location to transmit a cellular telephone call to the object.
4. The method according to claim 1 wherein the message accesses the internet to determine the location of the destination.
5. The method according to claim 1 wherein the signal includes GPS coordinates of the location of the object.
6. The method according to claim 1 wherein the object is part of an ad-hoc internet group.
7. The method according to claim 1 wherein the object is part of a geo spatial web.
8. The method according to claim 1 wherein transmitting and receiving the message includes transmitting and receiving the messages wirelessly.
9. The method according to claim 1 wherein the navigation system is on a vehicle.
10. A method for entering a destination into a vehicle navigation system, said method comprising:
using a cellular telephone on the vehicle to call a cellular telephone at the destination;
receiving the cellular telephone call by the cellular telephone at the destination and determining that the call is asking for GPS coordinates of the destination;
sending the GPS coordinates of the destination to the cellular telephone at the navigation system, where the cellular telephone at the destination has a GPS receiver and where the GPS receiver provides the GPS coordinates, and the cellular telephone at the destination is in communication with a TCP/IP device with a known fixed location, and the known fixed location of the TCP/IP device is used to refine the GPS coordinates that are transmitted back to the navigation system;
displaying the destination on a screen that is part of the navigation system, where the destination is displayed as an icon at a location on a map; and
selecting on the icon on the screen as the destination.
11. A system for entering a destination into a navigation system, said system comprising:
means for transmitting a message from the navigation system to an object at the destination;
means for receiving the message by the object at the destination and determining that the message is asking for a signal identifying the destination;
means for transmitting the signal identifying a location of the object back to the navigation system, where the object location is determined using both location data from a fixed location TCP/IP device with which the object is participating in a piconet and GPS location data from a GPS receiver in the object;
means for displaying the location on a screen; and
means for selecting the location as the destination.
12. The system according to claim 11 wherein the message accesses the internet to determine the location of the destination.
13. The system according to claim 11 wherein the object is part of an ad-hoc internet group.
14. The system according to claim 11 wherein the object is part of a geo spatial web.
15. The system according to claim 11 wherein the means for transmitting and receiving the messages transmits and receives the messages wirelessly.
16. The system according to claim 11 wherein the navigation system is on a vehicle.
17. The method according to claim 1 wherein displaying the location on the screen is performed by displaying the location as an icon on a map, and wherein selecting the location is performed by selecting the icon.
18. The system according to claim 11 wherein the means for displaying the location on the screen displays the location as an icon on a map, and wherein the means for selecting the location selects the icon.
19. The system according to claim 11 wherein the piconet is a very small area network such that the location of the object is equivalent to a location of the fixed location TCP/IP device, and the location data from the fixed location TCP/IP device is combined with the GPS location data in order to increase the precision of the signal identifying the destination.
