Abstract
The invention relates to a manually controlled input device for a computer which comprises a graph! graphics card for controlling a monitor video screen by means of! via a video signal, as a simulation and in the form! of a mechanical small-size spraying device (air brush) whose operating parameters are composed of three space coordinates, the air pressure of the ink spraying jet and the ink quantity therein. Synchronization signals from the video card are used in conjunction with an optical coupling between the input device and the video screen, to determine the spacial coordinates of the input device relative to the video screen.
