Abstract

In one embodiment, a navigation system provides predictive natural guidance utilizing a mobile landmark based on location data. The location data may be a schedule. A controller receives data of a schedule of a mobile landmark. The location data could be collected in real time or estimated. The mobile landmark may be a vehicle or a celestial body. The controller correlates a route from an origin location to a destination location and the location of the mobile landmark. The controller generates a message based on the correlation. The message is output during presentation of the route and references the mobile landmark.

Claims

1. A method comprising:

identifying a geographic location for a mobile landmark;

receiving a current location of a mobile device, the current location determined by position circuitry;

calculating, using a processor, a route from the current location to a destination location from data received from a geographic database, wherein the mobile landmark does not follow the route;

determining, using the processor, a correlation between the route and the geographic location for the mobile landmark; and

generating an assurance message based on the correlation between the route and the geographic location for the mobile landmark;

wherein the assurance message includes a graphic indicative of the mobile landmark.

2. The method of claim 1, wherein the graphic indicative of the mobile landmark depicts a celestial body.

3. The method of claim 1, wherein the graphic indicative of the mobile landmark depicts an airplane.

4. The method of claim 1, wherein the graphic indicative of the mobile landmark indicates a wrong direction.

5. The method of claim 1, further comprising:

presenting the route and the assurance message on the mobile device.

6. The method of claim 1, further comprising:

receiving a schedule for the mobile landmark; and

defining a landmark vector from the schedule, wherein the landmark vector references an expected position for the geographic location of the mobile landmark and direction of the mobile landmark according to the schedule.

7. The method of claim 6, further comprising:

defining a mobile device vector based on the route and a current time, wherein determining the correlation comprises;

comparing the landmark vector and the mobile device vector.

8. The method of claim 7, further comprising:

calculating an angle between the landmark vector and the mobile device vector.

9. The method of claim 1, further comprising:

removing a portion of the route; and

incorporating the assurance message into the route.

10. A method comprising:

identifying a geographic location for a mobile landmark;

receiving a current location of a mobile device, the current location determined by position circuitry;

generating, using a processor, a route based on the current location and a destination location based on a geographic database, wherein the mobile landmark does not follow the route;

determining, using the processor, a correlation between the route and the geographic location for the mobile landmark;

generating an assurance message based on the correlation between the route and the geographic location for the mobile landmark;

wherein the assurance message includes a graphic indicative of the mobile landmark;

augmenting the route to include the assurance message; and

sending the route to the mobile device.

11. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

identifying a geographic location for a landmark;

receiving a current location of a mobile device, the current location determined by position circuitry;

generating a route from the current location to a destination location based on data from a geographic database;

determining, using a processor, a correlation between the route and the geographic location for the landmark;

receiving a schedule for the landmark;

defining a landmark vector from the schedule, wherein the landmark vector references an expected position and direction of the landmark according to the schedule; and

generating an assurance message based on the correlation between the route and the geographic location for the landmark;

wherein the assurance message includes a graphic indicative of the landmark.

12. The apparatus of claim 11, wherein the landmark does not follow the route.

13. The apparatus of claim 11, wherein the graphic indicative of the landmark depicts a celestial body or an airplane.

14. The apparatus of claim 11, wherein the graphic indicative of the landmark indicates a wrong direction.

15. The apparatus of claim 11, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

defining a mobile device vector based on the route, wherein determining the correlation comprises;

comparing the landmark vector and the mobile device vector.

16. The apparatus of claim 15, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

calculating an angle between the landmark vector and the mobile device vector.

17. The apparatus of claim 16, wherein the assurance message is generated in response to the angle being in a threshold range of angles.

18. A non-transitory computer readable medium including instructions that when executed are operable to:

receive data of an expected geographic location of a mobile landmark;

calculate a route between a current location of a mobile device and a destination, wherein the current location of the mobile device is detected by position circuitry;

compare the route to the expected location of the mobile landmark; and

generate a message including turn-by-turn directions that references the mobile landmark according to the expected location of the mobile landmark.

19. The non-transitory computer readable medium of claim 18, wherein the message graphically references the mobile landmark, and the message is to be displayed to describe the route.

20. The non-transitory computer readable medium of claim 18, wherein the message includes audio.

21. A method comprising:

identifying a geographic location for a landmark;

receiving a current location of a mobile device, the current location determined by position circuitry;

generating, using a processor, a route from the current location to a destination location, wherein the landmark does not follow the route;

determining, using the processor, a correlation between the route and the geographic location for the landmark; and

generating an assurance message based on the correlation between the route and the geographic location for the landmark;

wherein the assurance message includes a graphic indicative of the landmark,

wherein the graphic indicative of the landmark depicts a celestial body.
