Abstract
When one of rollers Xa and Xb rotating about the X axis rotates, an image on the screen moves in the X direction; when both rollers rotate in the same direction at the same time, the image rotates about the X axis; and when both rollers rotate in opposite directions to each other at the same time, the image rotates about the Z axis. With rollers Ya and Yb, movement in the X direction, rotation about the Y axis, and rotation about the Z axis can be input. When a roller Za rotates, the image moves in the Z direction. With the above structure, movement data and rotational data in the three-dimensional space can be input.
