1. A method of controlling a visual operator interface comprising a plurality of predefined areas, which include one or more monitoring areas configured to display visual elements representing a current state of a technical system, the method comprising:
determining that one of the monitoring areas is to be prioritized;
locating an operator's attention in one of the predefined areas; and
initiating an incomplete visibility decrease in at least one other area of the visual operator interface, wherein the prioritized monitoring area is unaffected by the visibility decrease and the visibility decrease is conditional upon whether the operator's attention is already directed at the prioritized area;
wherein at least one of the following holds:
a) the predefined areas of the visual operator interface correspond to one or more of:
a complete image of an installed visual display,
a subarea of an image of an installed visual display,
a visual display of a handheld device;

b) the predefined areas are juxtaposed as seen from an operator position, in such manner that at least one area extends into the operator's peripheral visual field;
c) the predefined areas correspond to different windows of a graphical user interface, which are positionable in a mutually concealing arrangement.
