1. A three-dimensional display device comprising:
- display means for displaying a cursor as virtually located in a three-dimensional space and as moving in said space according to a velocity vector that can be changed in response to control signals representing said cursor;
input means for inputting first parameter signals including two parameters that three-dimensionally define the direction of said velocity vector;
control means connected between said display means and said input means for generating said control signals to display the cursor at a position virtually located in said three-dimensional space and with a configuration such that the cursor appears to move at a constant speed in a fixed direction when said parameter signals indicate no change and such that the cursor appears to change its moving direction in a direction and at a rate represented by said first parameter signals when a change occurs in said parameter signals.

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.

12. A method of controlling display of a cursor in a three-dimensional space, comprising the steps of:
-
displaying a cursor as a moving image located in a three-dimensional space on a display means; supplying first parameter signals from an input device, including two parameter signals representing a three-dimensional change of direction of the movement of said cursor; generating control signals based on said first parameter signals, the control signals controlling the display of said cursor to move said cursor in a constant direction and at a constant speed when said first parameter signals represent no change and to move said cursor to change direction when said first parameter signals are changed. - View Dependent Claims (13, 14, 15, 16, 17)
