Abstract: End lines are ingeniously displayed so as to enhance the function of reaching a target without impairing safety. Visibility is improved and the driver is assisted to select a route, so that reaching a target is ensured. At the same time, the driver's burden is reduced and thereby safety is enhanced.

Abstract: [Problem] The present invention relates to a navigation system. An area where an aircraft remains for a unit time is computed as a cell using pieces of element data such as a type, a performance, a speed, and a direction of the aircraft, a trouble, and an air stream, an avoidance vector for separating overlapped cells is determined when the plural cells are overlapped with each other, and the aircraft flies manually or automatically according to the avoidance vector, whereby the navigation system prevents an accident from happening. [Solving Means] In the navigation system, using a generating line which is of a route predicted by counting a vector defined by the speed and the direction of the aircraft in the pieces of element data such as a rotating axis, the performance, the air stream, and the trouble, a conical area is computed as the cell to manually or automatically perform the avoidance for separating the cells.

Abstract: A navigation apparatus, and method, comprised of an input unit, central processing unit, output unit, locator, processing devices, computing and retrieving devices, and storage unit. The navigation apparatus and method computes or retrieves and outputs or displays a unit area not suitable for travel, that is, a “cell”, from a destination, based on, for example, a type of moving object or data of a navigated area. The navigation apparatus and method thereby presents cells as realistic, useful, basic information based on various travel factors and enables such cells to be avoided and the destination to be reached.

Abstract: A navigation apparatus which includes an input section, a central processing section, a display section and a memory section is mounted on a moving object. When an initial or current position and destination of the moving object are provided to the central processing section, the apparatus produces two or more possible routes along which the moving object can move to reach the destination after starting from the current position by using map data stored in the memory section. The initial or current position, destination and possible routes are repeatedly calculated, updated and indicated on a screen of the display section. The two or more possible routes are repeatedly produced by a processor and calculation/retrieval circuitry. A connection route existing between the two or more possible routes may be retrieved and repeatedly indicated. Furthermore, a possible area containing the possible routes may be retrieved and repeatedly indicated.

Abstract: A navigation system and a method therefor arranged to be mainly adapted to a driver but the same is as well as adapted to a pedestrian as a portable type according to an embodiment in which devices such as a distance sensor and an azimuth sensor are not used. When information about the passage through which a moving object is moving at this very moment, such as a signal transmitted from a transmitter disposed in each passage, electric waves emitted from an orbit satellite, results of detections made by the distance sensor and the azimuth sensor or information supplied by a user, is supplied, an estimation of a result of a travel through the passage while performing no right or left turn, and an estimation of a result of a travel through a lane the way of which is particularly determined previously are respectively indicated as a travelling line. When a target is set, both the target and the travelling line are indicated on the screen of a display device.
