The field of application of information processing systems in complex man-machine systems is still expanding as a result of ever-increasing automation. In the first stage of automation, physical labour was replaced by machines, leaving the mental aspects of the task to the human operator. Due to the increase of speed and capacity of information processing systems, combined with a simultaneous decrease of costprices, these systems found acceptance and brought in the next stage of automation, in which some of the mental aspects of the task were taken over. As a result this development has led and is still leading to a modification of the task of the human operator.
