Abstract
The disclosure relates to the display, by projection on a screen, of an image managed by a computer system and to the input of data into the data-processing system by the shifting of a location marker in relation to the screen. A device for display by the projection of an image on a screen incorporates a surface detector of infrared radiation positioned behind the projection objective by means of a mirror separating the visible radiation and the infrared radiation. This display device is complemented by an infrared emitter with directional radiation, with which the observer traces a location marker on the screen which may take the form of a visible pointer overprinted on the image.
