Abstract

A navigation device provided with an Internet communication means, a browser means for connecting to a specified home page according to a uniform resource locator (URL) and a memory for storing a data table of URLs of home pages established for respective objects existing in the area of a map displayed by the navigation device, which device reads a URL of a specified home-page from the memory and presents a content of the home page obtained by using the URL when the user directly designates the object or the position on a map shown on the display screen.

Claims

1. A navigation device for determining a current position of the device and displaying the determined current position on a map shown on a display screen, which device is provided with a wireless internet communication means, a browser means for connection with any one of specified home pages established in the Internet'"'"'s world-wide web according to a specified URL, and a memory means for storing a data table for registering URLs of the home pages for providing information on respective stationary objects existing on the displayed map, and wherein data of a specified stationary object is obtained from digital map data by designating the specific stationary object on the displayed map shown on the display screen, a URL of a home page corresponding to the object data is read from the memory means and transferred to the browser means by which a content of the home page of the specified stationary object is then obtained and displayed on the display screen.

2. A navigation device for determining a current position of the device and displaying the determined current position on a map shown on a display screen, which device is provided with a wireless Internet communication means, a browser means for connection with any one of specified home pages established in the Internet'"'"'s world-wide web according to a specified URL, a base station separate from said navigation device, a memory specially used for registering a data table of URLs corresponding to information of respective objects on the displayed map is disposed in said base station from which a URL of a desired home page corresponding to a specified object data is obtained by wireless communication with the base station from the navigation device, and wherein said specified object data is obtained by designating the object on the map shown on the display screen, and then a URL of a home page corresponding to the object data is read from said memory and transferred to the browser means by which a content of the home page is then obtained and displayed on the display screen.

3. A navigation device for determining a current position of the device and displaying the determined current position on a map shown on a display screen, which device is provided with a wireless Internet communication means, a browser means for connection with any one of specified home pages established in the Internet'"'"'s world-wide web according to a specified URL, and a memory means having memory spaces corresponding to respective map numbers and storing URLs of specified home pages for respective objects existing in a mapped area specified by a map number in a corresponding one of the memory spaces, and wherein a URL of a home page corresponding to data of a designated object is read from the memory means according to the map number shown on the display screen and transferred to the browser means by which a content of the home page is then obtained and displayed on the display screen.

4. A navigation device as defined in claim 3, characterized in that the memory means having memory spaces corresponding to respective map numbers and used specially for storing the URLs of the home pages established for objects existing in respective map areas specified by the map numbers is disposed in a base station separate from the device from which a URL of a desired home page corresponding to a specified object data is obtained by wireless communication with the base station.

5. A navigation device for determining a current position of the device and displaying a determined current position on a map shown on a display screen, which device is provided with a wireless Internet communication means, a browser means for connection with any one of specified home pages established in the Internet'"'"'s world-wide web according to a specified URL, and a memory means for storing a data table of registered URLs of home pages with reference to respective positions on the map, and wherein according to a designation of a position of an object existing on the map shown on the display screen, a URL of the home page corresponding to the object data is read from the memory means and transferred to the browser means by which a content of the home page is then obtained and displayed on the display screen.

6. A navigation device as defined in claim 5, characterized in that the memory means for storing therein a data table of the registered URLs of the home pages corresponding to respective positions on the map is disposed in a base station separate from the device from which a URL of a desired home page corresponding to the specified object data is obtained by wireless communication with the base station.

7. A navigation device comprising, means for determining a current position of the device, a display screen for displaying a roadmap that includes the current position of the device, means for indicating on the displayed roadmap the determined current position of the device, a wireless Internet communication means, a browser means for connection with any one of specified home pages established in the Internet'"'"'s world-wide web according to a specified URL, a memory means for storing data corresponding to respective road maps for display and for storing URLs of specified home pages for respective stationary objects existing on each said road map, means for selecting at least one said stationary object on the displayed road map for causing the URL of a home page of each said selected stationary object to be read from the memory means according to the displayed roadmap and for displaying each said URL on the display screen, and means for selecting a URL displayed on the display screen and causing said browser means, through said wireless Internet communication means, to obtain the content of the home page of the selected URL and to display the home page on the display screen.

8. A navigation device as defined in claim 7, characterized in that the memory means is disposed in a base station separate from the device and each said URL corresponding to a specified object data is obtained therefrom by a separate wireless communication with the base station from the navigation device.
