Abstract
The present invention is related to a control device for a display state change on a monitor which includes a housing, a first input device mounted in the housing for determining a movement of a cursor on the monitor in an X- and a Y-directions, a second input device for determining two kinds of display state changes which include a movement of the cursor in a Z-direction and a display state change selected from a group consisting of a rotation operation and a picture change on the monitor, and a control circuit mounted in the housing for executing the display state changes. Various preferred operation modes for controlling the display state change on a monitor are also disclosed in the present invention for purpose of providing a easily manipulated control device with more functions than the conventional mouse and track ball.
