Abstract
A navigation terminal device includes a map information display unit 771 for displaying, on a screen, the map information containing the location information retrieved by a web server 3, a destination display unit for displaying the destination searched from the map information displayed on the display screen by screen scrolling, a route drawing unit 773 for drawing the route connecting a reference point based on the location information retrieved by the web server 3 to the destination so as to be superimposed on the screen with the map information displayed thereon, and a route searching unit 774 for exchanging the display between the reference point and the destination when the destination is displayed but the reference point disappears from the screen, thereby following the route from the reference point to the destination according to the drawn route information. In this configuration, the operability of a terminal device having a small capacity of screen can be improved and the burden for the user can be relaxed.
