Abstract

A GPS device and method for quickly and automatically determining and implementing an appropriate scale or area for displaying simultaneously at least a current location and a previously designated or otherwise identified waypoint, trail, track, or other geo-referenced indicator associated with a location. Relative distance, direction, and other useful navigation information may also be determined and displayed.

Claims

1. A method of displaying at least two locations simultaneously on a display component of a GPS device, the method comprising the steps of:

(a) allowing for identifying a first location;

(b) determining a current location;

(c) determining automatically a change in a current display sufficient to simultaneously display both the first location and the current location; and

(d) implementing automatically the change in the current display so as to simultaneously display both the first location and the current location on the display component.

2. The method as set forth in claim 1, wherein the first location is a waypoint.

3. The method as set forth in claim 1, wherein the change in the current display involves a change in scale to display a different amount of area.

4. The method as set forth in claim 1, wherein the change in the current display involves displaying an at least partially different area.

5. The method as set forth in claim 1, further including the step of determining and displaying information regarding a relative distance and a relative direction from the current location to the first location.

6. The GPS device operable to implement the method set forth in claim 1.

7. A method of displaying at least two locations simultaneously on a display component of a GPS device, the method comprising the steps of:

(a) allowing for identifying a first location;

(b) allowing for identifying a second location;

(c) determining a current location;

(d) determining automatically, in response to a first activation, a change in a current display sufficient to simultaneously display both the first location and the current location;

(e) implementing automatically the first change in the first current display so as to simultaneously display both the first location and the current location on the display component;

determining automatically, in response to a second activation, a second change in the current display sufficient to simultaneously display both the second location and the current location; and

(g) implementing automatically the second change in the current display so as to simultaneously display both the second location and the current location on the display component.

8. The method as set forth in claim 7, wherein the first location is a waypoint.

9. The method as set forth in claim 7, wherein the change in the current display involves a change in scale to display a different amount of area.

10. The method as set forth in claim 7, wherein the change in the current display involves displaying an at least partially different area.

11. The method as set forth in claim 7, further including the step of determining and displaying information regarding a relative distance and a relative direction from the current location to the first location.

12. The GPS device operable to implement the method set forth in claim 7.

13. The GPS device as set forth in claim 12, further including a dedicated control mechanism which when activated a first time accomplishes the first actuation, and which when activated a second time accomplishes the second actuation.

14. A method of displaying at least two locations simultaneously on a display component of a GPS device, the method comprising the steps of:

(a) allowing for identifying multiple locations;

(c) determining a current location;

(d) allowing a user to select one of the multiple locations;

(e) determining automatically, in response to an activation, a change in a current display sufficient to simultaneously display both the selected one of the multiple locations and the current location; and

(f) implementing automatically the change in the current display so as to simultaneously display both the selected one of the multiple locations and the current location on the display component.

15. The method as set forth in claim 14, wherein one or more of the multiple locations is a waypoint.

16. The method as set forth in claim 14, wherein the change in the current display involves a change in scale to display a different amount of area.

17. The method as set forth in claim 14, wherein the change in the current display involves displaying an at least partially different area.

18. The GPS device operable to implement the method set forth in claim 14.

19. The GPS device as set forth in claim 19, further including a dedicated control mechanism which when activated a first time accomplishes the first actuation, and which when activated a second time accomplishes the second actuation.
