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.

First claim

What is claimed is:

1. A method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone, comprising:
dynamically varying a density of road labels displayed on a navigational map on a mobile phone, said density of road labels being selected for display being varied in density based on:
a function class of a current road being navigated by said mobile phone, and
only roads intersecting said current road along a navigated route following an upcoming maneuver.

2. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 1 , wherein said density of road labels being selected for display being varied in density further based on:
a distance to said upcoming maneuver.

3. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 1 , wherein said density of road labels being selected for display being varied in density for display further based on:
a speed said user device is travelling.

4. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 1 , wherein said density of road labels being selected for display being varied in density for display further based on:
a distance to said upcoming maneuver; and
a speed that said mobile device is travelling along a navigated route.

5. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 1 , wherein:
said upcoming maneuver is a navigated prompt for said mobile phone to navigate off said current road and enter a next road along a navigated route.

6. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone 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 road labels displayed on a navigational map on a mobile phone 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. A method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone, comprising:
dynamically varying a density of road labels displayed on a navigational map on a mobile phone, said density of road labels being selected for display being varied in density based on:
a predetermined number of roads preceding an upcoming maneuver, that are both intersecting a current route, and of a same function class or a more significant function class as a road being currently navigated.

9. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 8 , wherein said density of road labels being selected for display is varied further based on:
a speed said mobile phone is travelling.

10. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 8 , wherein:
said upcoming maneuver is an action for said mobile phone to navigate off said current road and enter a next road along a navigated route.

11. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 8 , wherein:
only road labels for a predetermined number of roads preceding said upcoming maneuver are displayed on said navigational map.

12. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 8 , wherein:
only road labels for roads within a predetermined distance of said upcoming maneuver are displayed on said navigational map.

13. A method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone, comprising:
dynamically varying a density of road labels displayed on a navigational map on a mobile phone, said density of road labels being selected for display being varied in density based on:
a predetermined number of roads preceding an upcoming maneuver, that are both intersecting a current route, and of a same function class or a more significant function class as a road that is to be navigated following said upcoming maneuver.

14. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 13 , wherein said density of road labels being selected for display is varied further based on:
a speed said mobile phone is travelling.

15. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 13 , wherein:
said upcoming maneuver is an action for said mobile phone to navigate off said current road and enter a next road along a navigated route.

16. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 13 , wherein:
only road labels for a predetermined number of roads preceding said upcoming maneuver are displayed on said navigational map.

17. The method for dynamically varying a density of road labels displayed on a navigational map on a mobile phone according to claim 13 , wherein:
only road labels for roads within a predetermined distance of said upcoming maneuver are displayed on said navigational map.
