Abstract

A navigation system includes a feature that allows a user to specify a type of point of interest (or business chain) and then receive a reminder when the user is in proximity to a location of the point of interest of the specified type (or business chain) while traveling in a geographic region.

Claims

1. A method of operation for a navigation system, the method comprising the steps of:

accepting identification by a user of a category of location type about which a reminder is desired;

using a geographic database to determine locations at which the identified category of location type are located in a geographic region;

later, while the user is traveling in the geographic region to a location other than a location of the identified category of location type, continuing to determine new current positions of the user;

comparing each new current position of the user as the user is traveling in the geographic region to locations of the category of location type identified by the user;

determining if one of the new current positions of the user is within a proximity threshold of any one of the locations of the category of location type identified by the user; and

informing the user with a reminder if one of the new current positions of the user is determined to be within the proximity threshold to one of the locations of the identified category of location type.

2. The method of claim 1 wherein the navigation system is installed in a vehicle.

3. The method of claim 1 further comprising the step of:

providing the user with guidance to follow a route to the one of the locations of the category of location type located within the proximity threshold to the user.

4. The method of claim 1 wherein the step of determining comprises comparing distances between each new current position of the user to positions of locations of the category of location type identified by the user.

5. The method of claim 1 wherein the step of determining comprises comparing distances between each new current position of the user to positions of locations of the category of location type identified by the user;

and

wherein the step of informing is performed if any of said distances is less than the proximity threshold.

6. The method of claim 5 wherein said proximity threshold is configurable by the user.

7. The method of claim 1 wherein the step of determining comprises comparing travel times between each new current position of the user to positions of locations of the category of location type identified by the user.

8. The method of claim 1 wherein the step of determining comprises comparing travel times between each new current position of the user to positions of locations of the category of location type identified by the user;

and

wherein the step of informing is performed if any of said travel times is less than the proximity threshold.

9. The method of claim 8 wherein said proximity threshold is configurable by the user.

10. The method of claim 1 further comprising the step of:

storing data indicating said identification in a memory storage device associated with said navigation system, wherein said memory storage device is capable of retaining said data while said navigation system is not being used.

11. The method of claim 1 wherein said step of informing is performed while said user is traveling in a vehicle in which said navigation system is installed.

12. The method of claim 1 wherein said navigation system uses the geographic database to determine if the user is within the proximity threshold to a location of the category of location type identified by the user.

13. The method of claim 1 wherein said geographic database is installed with said navigation system.

14. The method of claim 1 wherein said step of informing continues to be performed while the user remains within said proximity threshold to a location of the identified category of location type.

15. The method of claim 14 wherein said step of informing ceases after the user is no longer within the proximity threshold of a location of the identified category of location type.

16. The method of claim 1 further comprising:

when performing the step of informing the user, also informing the user of the category of location type.

17. The method of claim 1 further comprises:

prior to the step of accepting identification, providing the user with categories of location types.

18. The method of claim 1 further comprising:

if said user is in within the proximity threshold of more than one location of the identified category of location type, informing the user that more than one location of the identified category of location type is within the proximity threshold; and

providing additional information about each location of the identified category of location type which is within the proximity threshold.

19. The method of claim 1 further comprising:

receiving real-time data relating to the category of location type; and

using the real-time data in conjunction with data relating to locations of the category of location type when determining if the user is within the proximity threshold to a location of the category of location type.

20. The method of claim 19 wherein the real-time data relates to one of:

gasoline prices, hotel room prices, and movies.

21. A method of operation for a navigation system, the method comprising the steps of:

accepting an identification by a user of a business chain about which a reminder is desired when the user is in proximity thereto;

later, continuing to determine new current positions of the user while the user is traveling in a geographic region,

using a geographic database to determine locations of the business chain in the geographic region;

comparing each new current position of the user while the user is traveling in the geographic region to locations of the business chain identified by the user;

determining if one of the new current positions of the user is within a proximity threshold of any one of the locations of the business chain; and

informing the user with a reminder if one of the new current positions of the user is within the proximity threshold of one of the locations of the business chain.

22. The method of claim 21 wherein the navigation system is installed in a vehicle.

23. The method of claim 21 further comprising the step of:

providing the user with guidance to follow a route to the one of the locations of the business chain located within the proximity threshold to the user.

24. The method of claim 21 wherein the step of determining comprises comparing distances between each new current position of the user to positions of locations of the business chain identified by the user.

25. The method of claim 21 wherein the step of determining comprises comparing travel times between each new current position of the user to positions of locations of the business chain identified by the user.

26. The method of claim 21 further comprising the step of:

storing data indicating said identification in a memory storage device associated with said navigation system, wherein said memory storage device is capable of retaining said data while said navigation system is not being used.

27. The method of claim 21 wherein said step of informing is performed while said user is traveling in a vehicle in which said navigation system is installed.

28. The method of claim 21 wherein said step of informing continues to be performed while the user remains within said proximity threshold of a location of the identified business chain.

29. The method of claim 21 further comprising:

when performing the step of informing the user, also informing the user of the business chain to which the user is within the proximity threshold of.

30. The method of claim 21 further comprising:

if the user is within the proximity threshold of more than one location of the identified business chain, informing the user that more than one location of the identified business chain is within the proximity threshold; and

providing additional information about each location of the business chain which is within the proximity threshold.

31. The method of claim 21 further comprising:

receiving real-time data relating to the business chain; and

using the real-time data in conjunction with data relating to locations of the business chain when determining whether the user is within the proximity threshold of a location of the business chain.
