Abstract

A display method and apparatus for a navigation system which is capable of easily and quickly specifying a destination in the navigation system when using a “Point of Interest (POI)” method by preventing unwanted POI names or types from appearing on the navigation system. The method includes the steps of displaying a POI name list based on an instruction specified by a user, selecting an unwanted POI name in the POI name list, removing all POIs having the unwanted POI name or having the unwanted POI type from the POI name list, and selecting a destination in the POI name list from which the unwanted POI name is removed for route guidance by the navigation system. If necessary, the above steps of selecting the unwanted POI name and removing the unwanted POI names from the POI name list are repeated.

Claims

1. A display method for a navigation system for guiding a user to a destination, comprising the following steps of:

displaying a “

Point of Interest (POI)”

name list that shows candidate destinations to visit based on an instruction specified by a user;

displaying at least one function key for selecting a group of POIs;

selecting an unwanted POI name in the POI name list;

selecting the function key for specifying a group of POIs in the POI name list;

removing all POIs that coincide with both the selected unwanted POI name and the selected group of POIs from the POI name list; and

selecting a destination in the POI name list from which the unwanted POI name has been removed for route guidance by the navigation system.

2. A display method as defined in claim 1, further comprising a step of repeating the step of selecting the unwanted POI name, the step of selecting the function key, and the step of removing the coincident POIs from the POI name list.

3. A display method as defined in claim 2, further comprising a step of determining an optimum route to the destination, thereby performing route guidance to the destination.

4. A display method as defined in claim 1, wherein said step of displaying the POI name list includes a step of determining a method of retrieving the POI names either by a place type or a place name.

5. A display method as defined in claim 1, wherein said step of displaying the POI name list includes a step of determining an order of listing the POI names either by distance from a current user position or by an alphabetical order.

6. A display method as defined in claim 1, wherein said step of removing the POIs includes a step of filling other POI names in spaces in the POI name list where the unwanted POI names have been removed.

7. A display method as defined in claim 1, wherein said step of removing the POIs includes a step of adding new POI names to the POI name list where the unwanted POI names have been removed, and wherein the unwanted POI names are removed from the new POI names before being added to the POI name list.

8. A display method for a navigation system for guiding a user to a destination, comprising the following steps of:

displaying a “

Point of Interest (POI)”

name list that shows candidate destinations to visit based on an instruction specified by a user;

displaying a first function key for specifying a name of POIs and a second function key for specifying a type of POIs;

selecting an unwanted POI name in the POI name list;

selecting either the first function key for removing POIs having the unwanted POI name or the second function key for removing POIs of same type as that of the unwanted POI name;

removing all POIs having the unwanted POI name from the POI name list when the first function key is selected and removing all POIs in the same type as that of the unwanted POI name when the second function key is selected; and

selecting a destination in the POI name list from which the unwanted POI name has been removed for route guidance by the navigation system.

9. A display method as defined in claim 8, further comprising a step of repeating the step of selecting the unwanted POI name, the step of, selecting the first or second function key, and the step of removing the POIs that coincide with the selected unwanted POI name and the selected first or second function key from the POI name list.

10. A display method as defined in claim 9, further comprising a step of determining an optimum route to the destination, thereby performing route guidance to the destination.

11. A display method as defined in claim 8, wherein said step of displaying the POI name list includes a step of determining a method of retrieving the POI names either by a place type or a place name.

12. A display method as defined in claim 8, wherein said step of displaying the POI name list includes a step of determining an order of listing the POI names either by distance from a current user position or by an alphabetical order.

13. A display method as defined in claim 8, wherein said step of removing the POIs includes a step of filling other POI names in spaces in the POI name list where the unwanted POI names have been removed.

14. A display method as defined in claim 8, wherein said step of removing the POIs includes a step of adding new POI names to the POI name list where the unwanted POI names have been removed, and wherein the unwanted POI names are removed from the new POI names before being added to the POI name list.

15. A display apparatus for a navigation system for guiding a user to a destination, comprising:

means for displaying a “

Point of Interest (POI)”

name list that shows candidate destinations to visit based on an instruction specified by a user;

means for displaying at least one function key for selecting a group of POIs;

means for selecting an unwanted POI name in the POI name list;

means for executing the function key for selecting a group of POIs in the POI name list;

means for removing all POIs that coincide with both the selected unwanted POI name and the selected group of POIs from the POI name list; and

means for selecting a destination in the POI name list from which the unwanted POI name has been removed for route guidance by the navigation system.

16. A display apparatus as defined in claim 15, further comprising means for repeating processes of selecting the unwanted POI name, selecting the function key, and removing the coincident POIs from the POI name list.

17. A display apparatus as defined in claim 16, further comprising means for determining an optimum route to the destination, thereby performing route guidance to the destination.

18. A display apparatus as defined in claim 15, wherein said means for displaying the POI name list includes means for determining a method of retrieving the POI names either by a place type of a place name.

19. A display apparatus as defined in claim 15, wherein said means for displaying the POI name list includes means for determining an order of listing the POI names either by distance from a current user position or by an alphabetical order.

20. A display apparatus as defined in claim 15, wherein said means for removing the POIs includes means for filling other POI names in spaces in the POI name list where the unwanted POI names have been removed.

21. A display apparatus as defined in claim 15, wherein said means for removing the POIs includes means for adding new POI names to the POI name list where the unwanted POI names have been removed, and wherein the unwanted POI names are removed from the new POI names before being added to the POI name list.

22. A display apparatus for a navigation system for guiding a user to a destination, comprising:

means for displaying a “

Point of Interest (POI)”

means for removing all POIs having the unwanted POI name from the POI name list when the first function key is selected and removing all POIs in the same type as that of the unwanted POI name when the second function key is selected; and

means for selecting a destination in the POI name list from which the unwanted POI name has been removed for route guidance by the navigation system.

23. A display apparatus as defined in claim 22, further comprising means for repeating processes for selecting the unwanted POI name, selecting the first or second function key, and removing the POIs that coincide with the selecting unwanted POI name and the selecting first or second function key from the POI name list.
