ABSTRACT:
A control system that undergoes lateral and rotational movement to selectively and accurately position an image on the screen of a video monitor. A movement detector is interfaced with a microprocessor to detect and interpret the movement of the control system. The control system comprises a shaft and a bar having a bar axis. The bar is rotatable around the shaft about the bar axis and slideable along the shaft in a direction parallel to the bar axis. Accordingly, movement of the bar with respect to the shaft causes a corresponding movement or positioning of the image on the screen.
