The system includes a sensor arrangement (5, 5', 5'') arranged in the area of the seat (1, 1', 1''), which recognizes an occupation of the seat and provides a corresponding signal to an evaluation arrangement (9). The sensor arrangement may include an infrared sensor arranged in a defined distance from the seat, or a pressure sensor arranged in the seat and/or in the back of the seat. The seat is especially associated with a computer terminal and a screen (3, 3', 3'') arranged in firm relationship to the seat and the back of the seat.
