Abstract

Methods for dynamically varying label density and label placement on a map display used in mapping and/or navigation solutions. Label density and label placement on a map display are adjusted dynamically based on: a function class of a road being navigated, a function class of a road to be navigated following an upcoming maneuver, a distance to an upcoming maneuver, and/or a speed a device receiving mapping/navigation services is travelling.

Claims

1. A method for dynamically varying a density of road labels displayed on a given displayed navigational map having a given density of displayed features, comprising:

dynamically varying a density of road labels displayed on a user device as a navigational map, said displayed road labels being varied in density for display based on;

a function class of a first road being navigated by said user device, and

a function class of a next road to be navigated along a navigated route following an upcoming maneuver.

2. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein said displayed road labels are varied in density for display further based on:

a distance to said upcoming maneuver.

3. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein said displayed road labels are varied in density for display further based on:

a speed said user device is travelling.

4. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein said displayed road labels are varied in density for display further based on:

a distance to said upcoming maneuver; and

a speed said user device is travelling.

5. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein:

said upcoming maneuver is an action for said user device to leave said first road and enter said next road along said navigated route.

6. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein:

said road labels are displayed on said navigational map for only a predetermined number of roads preceding said upcoming maneuver.

7. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein:

said road labels are displayed on said navigational map only for roads located within a predetermined distance of said upcoming maneuver.

8. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein:

said user device is a vehicle navigation system.

9. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1, wherein:

said user device is a mobile phone.

10. A method for dynamically varying a density of road labels displayed on a given displayed navigational map having a given density of displayed features, comprising:

dynamically varying a density of road labels displayed on a user device navigational map, with respect to a displayed density of said navigational map, said displayed road labels being varied in density for display based on;

a function class of a first road being navigated by said user device, and

a distance to an upcoming maneuver.

11. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 10, wherein said displayed road labels are varied in density for display further based on:

a speed said user device is travelling.

12. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 10, wherein:

said upcoming maneuver is an action for said user device to leave said first road and enter said next road along said navigated route.

13. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 10, wherein:

said road labels are displayed on said navigational map for only a predetermined number of roads preceding said upcoming maneuver.

14. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 10, wherein:

said road labels are displayed on said navigational map only for roads located within a predetermined distance of said upcoming maneuver.

15. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 10, wherein:

said user device is a vehicle navigation system.

16. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 10, wherein:

said user device is a mobile phone.

17. A method for dynamically varying a density of road labels displayed on a given displayed navigational map having a given density of displayed features, comprising:

dynamically varying a density of road labels displayed on a user device navigational map, with respect to a displayed density of said navigational map, said displayed road labels being varied in density for display based on;

a function class of a first road being navigated by said user device, and

a speed said user device is traveling.

18. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 17, wherein:

said user device is a vehicle navigation system.

19. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 17, wherein:

said user device is a mobile phone.
