Abstract

Typically, users click or otherwise show interest in a particular geographic region on a map to indicate their desire to center and/or zoom in on that location. However, it is more likely that a user has a higher interest in popular points of interest in a region than with a point of selection on a map. By employing popularity map data, the map navigation can be biased towards popular points of interest relative to a user'"'"'s selection. This allows users to more effectively navigate through maps, rather than through trial and error selections based solely on geography. Some instances utilize weighting of popularity points to determine an offset distance from a user'"'"'s selection. Other instances can employ a most popular point nearest a user'"'"'s selection as a bias point. Included popularity points for biasing can be determined based on a percentage of a visualized map image presented to a user.

Claims

1. A system that enhances map navigation, comprising:

a popularity data assessment component that receives popularity map data corresponding, at least in part, to a visualized map region and derives a subset of the popularity map data based on, at least in part, a map navigation input and the visualized map region; and

a popularity biasing component that employs the popularity map data subset to bias the map navigation input.

2. The system of claim 1, the popularity biasing component employs a weighted average of nearest popular points from the popularity map data subset to determine the map navigation input biasing.

3. The system of claim 1, the popularity biasing component employs a single most popular point from the popularity map data subset to determine the map navigation input biasing.

4. The system of claim 1, the popularity data assessment component determines the popularity map data subset based on a threshold.

5. The system of claim 4, the threshold derived from a percentage of the visualized map region.

6. The system of claim 4, the threshold derived based on a minimum level of popularity of popular points in the popularity map data.

7. The system of claim 1, the map navigation input comprising a system and/or user map center request and/or map zoom request on a geographical map location.

8. The system of claim 1, the popularity data assessment component determines the popularity map data subset based on, at least in part, user and/or system preferences for types of popularity data.

9. The system of claim 1, the popularity biasing component utilizes a bias based on user and/or system preferences for popularity map data utilized in the popularity map data subset.

18. A computer readable medium having stored thereon computer executable components of the system of claim 1.

20. A device employing the system of claim 1 comprising at least one selected from the group consisting of a computer, a server, and a handheld electronic device.

10. A method for assisting digital map navigation, comprising:

obtaining popular points for a map region viewed by a user;

selecting a subset of the popular points within a threshold;

determining a popular point center based on the subset; and

deriving a new center point for the map region based on a distance towards the popular center point.

11. The method of claim 10 further comprising:

shifting a viewing area of the map region towards the new center point; and

zooming the map region based on the new center point.

12. The method of claim 10 further comprising:

determining the popular point center based on a single most popular point of the subset and/or a weighted average of nearest popular points of a visual center point of the map region from the subset.

13. The method of claim 10 further comprising:

determining the threshold based on a percentage of a viewable portion of the map region.

14. The method of claim 10 further comprising:

determining the threshold based on a user and/or system preference.

15. The method of claim 10 further comprising:

determining the distance based on a normalized strength level of the subset of popular points.

16. The method of claim 10, the popular points based on prior collective user navigation behavior information.

19. A device employing the method of claim 10 comprising at least one selected from the group consisting of a computer, a server, and a handheld electronic device.

17. A system that augments map navigation, comprising:

means for receiving popularity map data corresponding, at least in part, to a visualized map region;

means for deriving a subset of the popularity map data based on, at least in part, a user'"'"'s geographical map selection point and the visualized map region; and

means for utilizing the popularity map data subset to bias the user'"'"'s geographical map selection point.
