摘要

The display and actuating device (1) comprises a screen (2), a camera (3) and a central processing and control device (13) connected with a bus (14). The reference images of different persons of the respective users of the display and actuating device, are stored in a reference memory (4). The camera registers a person approaching the display and actuating device, where the image signals of the camera (BK) and image signals of the reference memory (BR) are supplied to an image comparison device (5) which carries out a coincidence-analysis of the image signals.
