The invention relates to a method and a control device (2) for operating an electrically controllable technical device (1), in particular a machine, an installation, a device or a technical process. A control panel (4) with input means (6) for issuing control commands to the technical device (1) and for inputting data into the control device (T) by an operator (7) is provided in this case. This control panel (4) also comprises a graphics-enabled output means (8) for displaying subsets of information which is available overall for an operator (7). The important factor here is to provide at least one second screen layout, which is designed to display a second subset of information on the graphics-enabled output means (8) and is intended to be viewed from a relatively great distance, in particular from outside an immediate control range (9) of the control panel (4) or the technical device (1). Furthermore, the presence and/or absence of a person in the immediate control range (9) of the control panel (4) or the technical device (1) is detected automatically and automated changeover between a first screen layout and the second screen layout is effected on the basis of the determined state relating to the presence and/or absence of a person in the immediate control range (9) of the control panel (4) or the technical device (1).
