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.

Route search apparatus, route search method and computer-readable storage medium storing program

A route search apparatus comprises a road information storage part configured to store road information including link information comprised of single link information and composite link information; and a route searcher configured to search a recommended route between two different points using the link information. The single link information includes information regarding an approach link that is a link approaching to a node at one end of a target link, an exit link that is a link exiting from a node at the other end of the target link, and a cost of the target link for entering from the approach link and exiting to the exit link. The composite link information includes information regarding an approach link that is a link approaching to a node at one end of a target link array, an exit link that is a link exiting from a node at the other end of the target link array, and a cost of the target link array for entering from the approach link and exiting to the exit link.

If a destination set on a displayis a facility not having connection relation between facilities stored in a facility information DB, a scroll direction detecting unitthat detects a scroll direction of a mapdetects a direction instructed for scroll as the scroll direction and a display controlling unitperforms scroll of the mapin the scroll direction. In addition, if the set destination is a facility having the connection relation between the facilities, the scroll direction detecting unitthat detects a scroll direction of the mapdetects the scroll direction based on the connection relation of the destination and the direction instructed for scroll and the display controlling unitperforms the scroll of the mapto a position of a facility connected to the destination in the scroll direction.

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.

Touch panel type operation device, touch panel operation method, and computer program

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.
