Abstract

When specifying a Point of Interest (POI) as a destination in a navigation system, a relation between a POI and associated POIs is defined as a parentage. Detailed information such as polygon data, address, position, etc., is stored for a POI, and if the POI is a parent, a list of the child POIs or polygon data thereof also is stored. In setting a destination, the navigation system: (1) displays the detailed information and the polygon of the parent, and when a parent POI is selected from the POI list, (2) displays a list of the child POIs or polygons of the child POIs as requested, and (3) specifies a child POI from the list of the child POIs or the polygons of the child POIs to input a destination.

Claims

1. A method of selecting a destination in a navigation system by Point of Interest (POI), comprising:

displaying a POI list including parent POIs with which are associated at least one child POI;

selecting a POI from the POI list and displaying information relating to the selected POI, including whether the selected POI is a parent POI ;

displaying for a selected parent POI a list of associated child POIs; and

selecting a child POI from the list of child POIs.

2. A destination selecting method as claimed in claim 1, wherein the POI list is displayed as a result of selecting a category from a list of categories.

3. A destination selecting method as claimed in claim 1, wherein a route search is executed with the selected child POI as the destination.

4. A destination selecting method as claimed in claim 1, wherein the selected parent POI is a shopping mall and the child POI is a tenant in the shopping mall.

5. A destination selecting method as claimed in claim 1, wherein the child POI is a parking lot associated with the selected parent POI.

6. A destination selecting method as claimed in claim 1, wherein the child POI is an entrance or exit associated with the selected parent POI.

7. A method of selecting a destination in a navigation system by Point of Interest (POI), comprising:

displaying a POI list including parent POIs with which are associated at least one child POI;

selecting a POI from the POI list and displaying information relating to the selected POI, including whether the selected POI is a parent POI;

displaying for a selected parent POI polygon data of child POIs; and

selecting a child POI from the polygon of the child POI.

8. A destination selecting method as claimed in claim 7, wherein the POI list is displayed as a result of selecting a category from a list of categories.

9. A destination selecting method as claimed in claim 7, wherein, when a parent POI is selected from the POI list, a polygon of the parent is displayed.

10. A destination selecting method as claimed in claim 7, wherein, when the POI is a parent, link data of child POIs and also names of child POIs are stored.

11. A destination selecting method as claimed in claim 7, wherein a child POI is displayed with a polygon, and the polygons of multiple child POIs are displayed in linked fashion.

12. A destination selecting method as claimed in claim 7, wherein a route search is executed with the selected POI as the destination.

13. A destination input method as claimed in claim 7, wherein the selected parent POI is a shopping mall and the child POI is a tenant in the shopping mall.

14. A destination input method as claimed in claim 7, wherein the child POI is an entrance or exit associated with the selected parent POI.

16. An on-vehicle navigation system as claimed in claim 15, wherein parent POI information displayed by the control unit includes information indicating whether the parent POI possesses a child POI.

17. An on-vehicle navigation system as claimed in claim 15, wherein the control unit executes a route search for a selected child POI as a destination.

19. An on-vehicle navigation system as claimed in claim 18, wherein parent POI information displayed by the control unit includes information indicating whether the parent POI possesses a child POI.

20. An on-vehicle navigation system as claimed in claim 18, wherein the control unit displays the child POI with a polygon, and displays the polygons of multiple child POIs in a linked fashion.

15. An on-vehicle navigation system that displays POIs (Points of Interest) in the form of a list, and selects a destination POI from the POI list to thereby input a destination, the on-vehicle navigation system comprising:

a POI database containing, for each POI, information such as address, position, and, if the POI is a parent, a list of associated child POIs, and

a control unit that displays, when a parent POI is selected from the POI list, the information of the parent, and displays the list of child POIs on request.

18. An on-vehicle navigation system that displays POIs (Points of Interest) in the form of a list, and selects a destination POI from the POI list to thereby input a destination, the on-vehicle navigation system comprising:

a POI database containing, for each POI, information such as polygon data, address, position, and, if the POI is a parent, polygon data of associated child POIs, and

a control unit that displays, when a parent POI is selected from the POI list, the information and a polygon of the parent, and displays the polygon of a child POI on request.
