Abstract

A system for selectively acquiring, processing and displaying 3-D waypoints in a manner suitable for the purpose of providing selected hands-free navigation guidance to a user. The system includes a plurality of multi-function devices for defining a frame of reference, at least one of the plurality being adapted to be carried by the user. A communication link provides communication between the plurality of multi-function device means to form a mesh network. The multi-function devices calculate, exchange and process waypoint information indicative of the location of itself, the device carried by the user, and at least one other the device means to thereby provide the route taken by the user. A display gives a 3-D navigation guidance to the user.

Claims

1. A tracking system for acquiring and exchanging 3-D positions to provide navigational guidance to a user, comprising:

a plurality of multi-function devices each defining a frame of reference, at least one of said plurality being adapted to be carried by said user;

a communication link for linking communication between said plurality of multi-function devices to form a mesh network;

said plurality of multi-function devices being adapted to calculate, exchange and process waypoint information indicative of the location of itself, the device carried by said user, and at least one other said device to thereby provide the route taken by said user; and

a display on said multi-function device carried by said user for displaying a 3-D navigation guidance to said user.

2. The system of claim 1, wherein a portion of said plurality of multi-function devices are fixedly located in known positions.

3. The system of claim 2, wherein a different portion of said plurality of multi-function devices are emplaced at relative locations with respect to said known positions.

4. The system of claim 1, wherein each multi-function device periodically updates its calculation exchange and process of waypoint information.

5. The system of claim 1, wherein said display on said multi-function device carried by said user provides hands free 3-D navigation guidance.

6. The system of claim 1, which further includes a plurality of users, each carrying a multi-function device.

7. The system of claim 1, which further includes a switch for permitting the user to determine the form of the navigation signal, said form including at least an evacuation signal for evacuating the area proximate said user, a location signal for locating another multi-function device, and a retreat signal for showing the reverse path taken by said user.

8. The system of claim 7, wherein said switch is activated by said user.

9. The system of claim 7, wherein said switch is activated by an external command.

10. The system of claim 1, wherein said display is adapted to depict a current navigational task and an anticipated next navigational task.

11. A tracking system for acquiring and exchanging 3-D positions to provide navigational guidance to a user, comprising:

a plurality of multi-function device means for defining a frame of reference, at least one of said plurality being adapted to be carried by said user;

communication link means for linking communication between said plurality of multi-function device means to form a mesh network;

said plurality of multi-function device means being adapted to calculate, exchange and process waypoint information indicative of the location of itself, the device means carried by said user, and at least one other said device means to thereby provide the route taken by said user; and

display means on said multi-function device means carried by said user for displaying a 3-D navigation guidance to said user.

12. The system of claim 11, wherein a portion of said plurality of multi-function device means are fixedly located in known positions.

13. The system of claim 12, wherein a different portion of said plurality of multi-function device means are emplaced at relative locations with respect to said known positions.

14. The system of claim 11, wherein each multi-function device means periodically updates its calculation exchange and process of waypoint information.

15. The system of claim 11, wherein said display means on said multi-function device means carried by said user provides hands free 3-D navigation guidance.

16. The system of claim 11, which further includes a plurality of users, each carrying a multi-function device means.

17. The system of claim 11, which further includes switch means for permitting the user to determine the form of the navigation signal, said form including at least an evacuation signal for evacuating the area proximate said user, a location signal for locating another multi-function device means, and a retreat signal for showing the reverse path taken by said user.

18. The system of claim 17, wherein said switch means is activated by said user.

19. The system of claim 17, wherein said switch means is activated by an external command.

20. The system of claim 11, wherein said display means is adapted to depict a current navigational task and an anticipated next navigational task.
