Abstract: This utility model relates to systems for interfacing with a computer via control of an image created on a projector screen and can be used for the interaction of a user with the computer during presentations, training sessions or educational events. The electro-optical pointing device comprises a source of radiation in the form of a light wand and a video camera. The video camera is connected to the computer and records the movement of a light spot over the screen, onto which an image being transmitted from the computer is projected. The source of radiation is a laser or a light-emitting diode emitting radiation in the infrared spectral range. An infrared range light filter is mounted in front of the lens of the video camera. The utility model makes it possible to simplify the design of the device whilst maintaining the operational efficiency thereof.
