Abstract

If a destination set on a display 3 is a facility not having connection relation between facilities stored in a facility information DB 84, a scroll direction detecting unit 92 that detects a scroll direction of a map 31 detects a direction instructed for scroll as the scroll direction and a display controlling unit 94 performs scroll of the map 31 in the scroll direction. In addition, if the set destination is a facility having the connection relation between the facilities, the scroll direction detecting unit 92 that detects a scroll direction of the map 31 detects the scroll direction based on the connection relation of the destination and the direction instructed for scroll and the display controlling unit 94 performs the scroll of the map 31 to a position of a facility connected to the destination in the scroll direction.

Claims

1. A navigation device configured to search for a route to a destination or provide guidance on a facility related to the destination, the navigation device comprising:

a facility information storing unit configured to store facilities and connection relations among the facilities;

a destination setting unit configured to set a first facility among the facilities stored in the facility information storing unit as the destination;

a displaying unit configured to display a map of a vicinity of the set destination;

an operating unit for receiving a scroll operation on the map by a user;

a scroll direction detecting unit configured to detect a scroll direction of the map based on the scroll operation received by the operating unit; and

a display controlling unit configured to scroll the map in the scroll direction detected by the scroll direction detecting unit, wherein

when the first facility has no stored connection relation with the other facilities,

the scroll direction detecting unit is configured to detect a direction of the scroll operation received by the operating unit as the scroll direction, and

the display controlling unit is configured to scroll the map in the scroll direction,

when the first facility set as the destination by the destination setting unit has a stored connection relation with a second facility among the other facilities,

the scroll direction detecting unit is configured to detect the scroll direction based on both (i) the stored connection relation of the first and second facilities and (ii) the direction of the scroll operation received by the operating unit, and

the display controlling unit is configured to scroll the map to a position of the second facility in the scroll direction and display the second facility as a destination candidate in a distinguishable manner,

the displaying unit is configured to function as the operating unit,

the first facility is a first station on a railroad track,

the second facility is a second station connected to the first station through the same railroad track, and

the display controlling unit is configured to, if a speed of the scroll operation on the operating unit is equal to or more than a predetermined speed, scroll the map to a station where an express train stops next in the scroll direction.

2. The navigation device according to claim 1, wherein

the display controlling unit is configured to display the second facility as the destination candidate with a specific icon, and

upon the user selecting the specific icon, the destination setting unit is configured to set the second facility as a new destination.
