Publication number: 20060184317Abstract: In each of the divided regions of the map, a redundancy of the region is estimated from the characteristics quantity such as fractal dimension of line segments of road. Then, regions with the same redundancies are combined to form a larger area so that the map is divided according to the redundancy. The areas thus formed are summarized by the summarization methods conforming to their redundancies and are combined into one map. In the map thus generated, only necessary information can be presented, with redundant information eliminated.Type: ApplicationFiled: February 15, 2006Publication date: August 17, 2006Inventors: Akinori Asahara, Masaaki Tanizaki, Kishiko Maruyama, Shigeru Shimada, Akio Sumizawa

Publication number: 20060106534Abstract: In a communication type navigation system that downloads maps, the present invention provides a map data transmission method that can reduce time before guiding is started. A map provision server searches for a traveling route connecting a starting place corresponding to current position information received from an on-vehicle terminal and a destination corresponding to destination information. The server generates guidance information for guiding the vehicle along the searched traveling route and generates a route vicinity map along the traveling route. The server generates traveling route information comprising the searched traveling route and the guidance information, and plural map information blocks into which the route vicinity map containing map information is divided along the traveling route, assigns transmission priority levels to the map information blocks, and transmits the map information blocks according to the transmission priority levels after transmitting the traveling route information.Type: ApplicationFiled: October 22, 2003Publication date: May 18, 2006Inventors: Yukihiro Kawamata, Mariko Okude, Manabu Kato, Yoshitaka Atarashi, Shigeru Matsuo, Takashi Nakahara, Masaaki Tanizaki, Kishiko Maruyama, Shigeru Shimada

Patent number: 6922630Abstract: A portable terminal with the function of walking navigation. The portable terminal displays information on its narrow screen so as to make it easy for the user (walker) to understand and realize an interface that enables the user to understand inputs of retrieving conditions intuitively, thereby saving the input labor. Assume now that a user (walker) 10 is lost while walking towards a destination 11. In such a case, the present invention enables necessary information to be compressed, for example, so as to display both direction and distance to the destination from a present place with an orientation and a length of an arrow on a small screen and further so as to match the orientation of the arrow with the direction of the destination in the actual space.Type: GrantFiled: April 29, 2004Date of Patent: July 26, 2005Assignee: Hitachi, Ltd.Inventors: Kishiko Maruyama, Shigeru Shimada, Toshiichirou Sasaki

Publication number: 20040236507Abstract: A car navigation system by which a user can easily grasp a drop-in target in the course of a route. In a summary road map displayed in a two- or one-window display representation, contents of a two-dimensional road map is properly selected and simplified, roads are made linear, roads connected to an intersection are made orthogonal so that the user can easily see it, the position of a vehicle is expressed by a mark, and even the running route is expressed with a predetermined color or the like. Accordingly, the system offers the user such a display form as able to easily refer to. When the user specifies a target at which the user wants to drop in, the drop-in target is displayed at a corresponding position on the summary road map in the form of a land mark.Type: ApplicationFiled: March 3, 2004Publication date: November 25, 2004Inventors: Kishiko Maruyama, Masaaki Tanizaki, Shigeru Shimada

Patent number: 6748317Abstract: A portable terminal has a function of walking navigation. The direction of a destination is displayed by an indicating arrow that always points in the direction of the destination. In the navigation processing, the user enters data to select a menu and/or set retrieving conditions on the setup screen. At first, the user gets the location information of the portable terminal, represented by a latitude/longitude or coordinates and an altitude, for example. Then, the user gets the direction information of the portable terminal, which is the direction of the tip of the portable terminal as determined by a compass, a gyro, or a clinometer. The location information and the direction information are set as terminal information for the retrieving conditions. The system controls retrieving of the database and retrieves the information corresponding to the selected menu, such as route guidance.Type: GrantFiled: May 5, 2003Date of Patent: June 8, 2004Assignee: Hitachi, Ltd.Inventors: Kishiko Maruyama, Shigeru Shimada, Toshiichirou Sasaki
