Abstract:
1. A map display manipulation apparatus comprising: a display portion to perform a map display to display a map based on map information; a manipulator to perform a manipulation to the map display, the manipulator being displaced in a three-dimensional coordinate system of x axis, y axis, and z axis, the x, y, and z axes being mutually orthogonal, a position detector to detect and output a coordinate set as a position of the manipulator in the three-dimensional coordinate system at each of successive detecting times during a detection duration from an initial detecting time via middle detecting times to a present detecting time; and a control circuit to control the map display in the display portion on a basis of a real time in response to receiving each of the coordinate sets of the manipulator during the detection duration, the control circuit performing an initial operation to display the map under an initial reduced scale with an initial map-center position centered in the display portion when receiving an initial coordinate set at the initial detecting time, the control circuit performing a present-time operation when receiving a present coordinate set at the present detecting time after receiving middle coordinate sets at the middle detecting times from the position detector, the present-time operation
