Abstract
A base station is installed in a predetermined area where a large number of target points are studded around the station. When the operator moves a mobile station around the base station, display means is provided for both or either of the base station that guides the operator and the mobile station, and a display screen of the display means displays 2 kinds of a Forward (foreground) mode and a Back (background) mode. In the Forward (foreground) mode, the display screen of the display means displays a landscape in a forward direction (opposite direction to the mobile station by 180° when seen from the base station) of the operator (mobile station) when the operator sees the base station from the current position of the mobile station, or from the next target point if the operator reaches the next target point. In the Back (backward) mode, the display screen of the display means displays the landscape in a backward direction (direction of the operator and the mobile station when seen from the base station) of the operator (mobile station) when the operator sees the base station from the current position of the mobile station, or from the next target point if the operator reaches the next target point. The relationship between the mobile station and the next target point is displayed on an imaginary landscape in an imaginary manner so that the operator can see the direction and distance for movement.
