Abstract

In some embodiments, a technique for providing location-based functionality comprises providing functionality, wherein the functionality uses information provided by a location-aware device.

Claims

1. A method for providing a three-dimensional display on a location-aware device, comprising:

generating a graphic representation of a topography of a given region on the location aware device using contour data, the graphic representation being a distorted map of the given region;

determining one or more locations of interest in the given region using (i) location information received on the location-aware device, and (ii) information specific to the device or to a user of the device, wherein determining one or more locations of interest includes correlating the one or more locations of interest to one or more graphic objects or features by selecting one or more tiepoints from a plurality of tiepoints;

representing one or more locations of interest on the representation using the one or more graphic objects or features; and

displaying the representation with the one or more graphic objects or features.

2. The method of claim 1, further comprising determining a current location of the location-aware device.

3. The method of claim 1, wherein at least one of the locations of interest is a location of another location-aware device that is identified from data contained on the location-aware device.

4. The method of claim 1, wherein displaying the representation includes displaying varying perspectives of the representation of the topography using the contour data.

5. The method of claim 4, wherein perspectives are varied in response to user controls.

6. The method of claim 1, further comprising receiving the contour data over a network.

7. The method of claim 1, further comprising retrieving the contour data from a memory of the location aware device in order to generate the representation of the topography of the region.

8. The method of claim 1, wherein the contour data includes Digital Elevation Model data.

9. The method of claim 1, wherein determining one or more locations of interest includes using a user'"'"'s address book.

10. The method of claim 1, wherein determining one or more locations of interest includes using user data stored on the location-aware device.

11. The method of claim 1, wherein determining one or more locations of interest includes determining a location of one or more friends of a user from a buddy list stored on the location-aware device.

12. A method for displaying a map, the method being performed by one or more processors and comprising:

displaying a distorted map of a region;

providing a plurality of correlations between the distorted map and a plurality of physical locations, the plurality of correlations including a plurality of tiepoints and the plurality of physical locations including a location of interest;

wherein the location of interest is within one or more physical boundaries of the region represented by the map;

correlating a physical location of the location of interest to a display location on the distorted map by selecting one or more tiepoints from the plurality of tiepoints; and

wherein displaying the distorted map includes representing the location of interest at the display location.

13. The method of claim 12, wherein correlating the physical location of interest to the display location on the distorted map includes interpolating the display location from the one or more tiepoints.

14. The method of claim 12, wherein selecting one or more tiepoints from a plurality of tiepoints includes selecting three tiepoints.

15. The method of claim 12, wherein selecting one or more tiepoints from a plurality of tiepoints includes selecting four tiepoints.

16. The method of claim 12, wherein correlating the physical location of interest to the display location on the distorted map includes solving a bilinear equation.

17. The method of claim 16, wherein the bilinear equation includes coefficients derived from the one or more tiepoints.

18. A method for displaying a location associated with a communication event on a location-aware device, the method comprising:

initiating a communication event on the location-aware device;

determining a location of the location-aware device when the communication is initiated;

recording the location of the location-aware device when the communication event was initiated; and

displaying a distorted map with (i) information about the communication event, including the location of the location-aware device when the communication event was initiated, and (ii) a plurality of display locations;

wherein displaying the distorted map includes (i) correlating a plurality of physical locations with the plurality of display locations by selecting one or more tiepoints from a plurality of tiepoints, and (ii) representing the plurality of physical locations at the corresponding plurality of display locations.

19. The method of claim 18, wherein the communication event is a telephone call.

20. The method of claim 18, wherein the communication event is receiving a message.

21. The method of claim 18, wherein the current location is determined by the location-aware device.
