Abstract

A navigation apparatus has a display portion displaying a map that is controlled by a remote control as a manipulator. The remote control has a gravitation sensor. The gravitation sensor serves as a position detector to detect a three-dimensional coordinate set (x, y, z) of the remote control. A reduced scale for the displayed map is changed based on a displacement in z axis while the displayed map is moved based on a horizontal displacement in xy-coordinate plane. The remote control may move obliquely in a direction being neither parallel with z axis nor orthogonal to z axis, drawing a U-shaped locus. In this case, the reduced scale is designated as a subject reduced scale based on the lowest coordinate in z axis; the displayed map is moved based on a product obtained by multiplying the horizontal displacement by a unit distance according to the subject reduced scale.

First claim

What is claimed is:

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,
the manipulator displaced parallel with the x axis and the y axis permitting the map to move laterally and longi…
