Abstract: A route search apparatus configured to search a route from a set place of departure to a set destination comprises network data that includes nodes and links representing a road network, an average cost value indicating an average of travel time of each of the links, and a variance value indicating a degree of variance of the travel time, and a route searcher configured to determine the route from the place of departure to the destination as a recommended route, based on the average cost value, the variance value and a weight coefficient of the variance value.

Abstract: Route search devices and programs obtain network data including nodes and links, and link information including (i) travel times for traveling a link included in the network data, the nodes and the links representing a road network, and (ii) for each entry link or each exit link, information that identifies a value representing statistical variation of travel times for the link, the entry link being a link entering a node at one end of the link, and the exit link being a link exiting from a node at another end of the link. The devices and programs search for a recommended route by taking into account (i) a travel time to a destination, based on the network data and the link information, and (ii) cost values identified based on a representative value of travel times for a link and a value representing statistical variation of the travel times.

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.

Abstract: Touch panel operation devices, methods, and programs set a touch-off determination time, and determine that the touch-off has occurred if the state at which the touch panel detects the user not touching the touch panel has continued for the set touch-off determination time or more after the touch-off was detected. When the user is touching the touch panel, the devices, methods, and programs acquire a touch coordinate, select an object corresponding to the acquired touch coordinate, and scroll-display the selected object based on a displacement of the acquired touch coordinate. The devices, methods, and programs determine whether the touch coordinate was acquired and displaced just before the touch-off was detected, and if the touch coordinate was acquired and displaced just before the touch-off was detected, set the touch-off determination time to be longer than if the touch coordinate was acquired and not displaced just before the touch-off was detected.

Abstract: A three-dimensional data processing device includes a bounding volume generating unit for generating a bounding volume of a solid body using stereographic data of the solid body, a view volume setting unit for setting a view volume based on a set viewpoint, and a culling processing unit for determining whether or not to draw the solid body within the view volume using the generated bounding volume. The bounding volume generating unit obtains bottom plane data of the solid body from the stereographic data, obtains an outer quadrangular frame that encloses a bottom plane of the solid body defined by the bottom plane data, obtains an inner quadrangular frame inscribed on the outer quadrangular frame, determines bounding volume geometry data using the inner quadrangular frame as a reference plane, and generates the bounding volume of the solid body from the bounding volume geometry data.

In response to a selection of a list item included in the list, a prior scroll direction that is the direction in which the list is scrolled immediately before the selection of the list item is acquired. Based on the prior scroll direction, a display mode of a list item frame that displays list item information related to the selected list item is set. The list item frame in displayed in the set display mode.

Abstract: Map display apparatus, methods, and programs store a first map image drawn based on map information stored in a map information storage unit and cause a partial range of the first map image to be displayed on a display unit. The apparatus, methods, and programs detect a pressed coordinate position where the display unit is pressed. When the pressing of the display screen is detected, the apparatus, methods, and programs cause a second map image drawn based on map information of an area vertically and horizontally twice as large as the display screen to be stored in a map image storage unit. The area has a center at a map position corresponding to the detected coordinate position. The apparatus, methods, and programs perform. follow-scrolling to move a display range of the second map image based on movement of the detected coordinate position.

Abstract: A navigation device includes a display unit, an operation detection unit, and an operation control unit. The display unit displays a map, at least a facility and a vicinity thereof on the map, and an icon. The operation detection unit detects a movement of the icon by a user. The operation control unit sets, when the map of the vicinity of the facility is displayed on the display unit, a predetermined area around a position of the facility as a lead-in area. The operation control unit also executes, when the icon is moved, a function of the icon with respect to the position of the facility if a post-movement position of the icon detected by the operation detection unit is within the lead-in area.

Abstract: In a three-dimensional data processing technique that uses stereographic data of a solid body to generate a bounding volume of the solid body, the generated bounding volume is used to determine whether or not to draw the solid body within a view volume. An inner quadrangular frame inscribed on an outer quadrangular frame, which encloses a plane outer profile of the solid body, is used as a reference plane for generating the bounding volume.
