Abstract: In a navigation apparatus, a CPU searches for a plurality of routes from a starting point to a destination. These routes share the same starting point and the destination, but vary in their course along the way. Then for route selection, the CPU refers to position information provided by a locator to determine on which of the routes the user is now moving. In this manner, the navigation apparatus can automatically select one route from several derived through the route search.

Abstract: In a main device 1, a processor 11 receives information about a destination point, and further generates guide image data representing a guide image for guiding a user who is driving a vehicle. A display unit 19 displays the guide image generated by the processor 11, thereby guiding the driving user to the destination point. When it is determined, while guiding the driving user, that the user is going to get off the vehicle, the processor 11 generates navigation data Dnvg including the information about the destination point, and transfers the navigation data to a sub-device 2. In the sub-device 2, a processor 21 generates, based on the received navigation data Dnvg, guide image data for outside of the vehicle representing a guide image for guiding the user who is traveling to the destination point on foot. A display unit 27 displays the guide image generated by the processor 21. Thus, it is possible to provide a navigation system that is convenient to use.

Abstract: In a navigation device (Unv), a processor 1 reads from a storage 4 directional object data (Ddr) onto a working area 3. The directional object data (Ddr) has a message plane and a plain plane, thereby representing a directional object whose planes are facing in each different direction. Based on the positional relationship between the user's current position and the directional object, the processor 1 determines which to render the message plane or the plain plane of the directional object. In the case of the message plane, the processor 1 renders it opaque. On the other hand, the processor 1 renders the plain plane transparent or translucent. In this manner, the resulting display image data generated by the navigation device (Unv) can represent maps meeting the user's demands and needs.

Abstract: A map information storage stores map information including roads, landmarks, and areas. An overlap determination unit determines whether a landmark and an area overlap with a road in consideration of a road and its width. A position changer moves the overlapping landmark and area to positions where they do not overlap with the road on width display. A changed map information storage stores map information including changed positional information of the landmarks and the areas. If the changed map information is displayed on a screen, the landmarks and the areas are displayed so as not to overlap with roads on width display.

Abstract: In order to implement a navigation device in which landmarks are much less monotonous, and the applicability thereof is wider, the navigation device of the present invention operates as follows. A landmark is displayed in either normal display (still) and emphatic display (animated) by referring to landmark information. Specifically, referring to for normal display is shape information and positional information in the landmark information, and for emphatic display, an emphatic display execution file therein is referred to. For emphatic display, a group of instruction described in the emphatic display execution file are interpreted and executed so that the landmark is animated.

Abstract: Data terminal equipment 31 receives a bonus-attached file including a shop bonus provided to a user, and a bonus identifier for uniquely identifying the bonus, and stores the bonus identifier included in the bonus-attached file. Data terminal equipment 21 previously stores another bonus identifier for uniquely identifying the bonus provided to the user of the data terminal equipment 31. Through data communications with the data terminal equipment 31, the data terminal equipment 21 requests the bonus identifier on the data terminal equipment 31 side. If determining that the bonus identifier received from the data terminal equipment 31 is as being the same as the data identifier stored therein, the data terminal equipment 21 provides the bonus specified by the bonus identifier to the user of the data terminal equipment 31. In such a manner, the data transmission system is improved in user's usability with no more need for printing coupons.

Abstract: On receipt of route information, map data in an area near the route is read. One intersection existing on the route is extracted from the read map data, and intersection-connected links connected to the intersection are extracted. The road widths from the center line to the right and left sides are specified for the intersection-connected links based on attribute data such as the actual road width of the intersection-connected links. New lines are drawn for all the intersection-connected links by translating the line representing the intersection-connected link as the center line rightward and leftward by the specified road widths, to determine right and left side lines of the intersection-connected link. Based on the thus-generated width-imparted intersection-connected links, an intersection shape is generated. This processing is repeated for all the intersections concerned.

Abstract: A navigation device at least includes a CPU and a detector generating a detection signal for determining whether a main device is used inside a vehicle or not. If determining, based on the detection signal from the detector, that the main device is used inside the vehicle, the CPU operates in on-vehicle mode to carry out first navigation (present position estimation and route search) suitable for use in the vehicle. Otherwise, the CPU operates in off-vehicle mode to carry out second navigation (present position estimation and route search) suitable for use outside of the vehicle. Thus, the navigation device can automatically switch its operation mode between on-vehicle mode and off-vehicle mode.

Abstract: In a navigation device assisting a driver of a vehicle to drive safely by presenting accurate information at the right time what is going on around his/her vehicle, an obstacle detection part detects any obstacle with the help of external information monitored by an external monitor part. By utilizing the vehicle's current position detected by an input part and a position detection part, and map data stored in a map data storage part, a route selection part searches for a route to a destination. Based on thus found route, current position, map data, and the external information from the obstacle detection part, a guiding part performs route guidance to the destination. A map data arranging part refers to the map data, information from the obstacle detection part and the input part, and object model display information from the object model display information storage part, and arranges any applicable object model onto a map data space.
