Abstract
A cursor moves at a constant velocity in a constant direction in a display space for displaying a three-dimensional image. When two parameters for representing a direction in a three-dimensional space are entered, the cursor changes its direction according to the entered direction at a rate determined by the entered magnitude. When a parameter for changing the velocity is entered, the cursor velocity is changed. It is not necessary to enter a three-dimensional coordinate to control the cursor to reach the desired position, and the manipulation of the cursor is very much simplified.
