Abstract
Technological advancement has changed the nature of interactions within
modern man-machine systems, with workload becoming more a load on the
mental capacities of the human systems component than on his/her physical
capabilities. Moreover increased system capabilities may have
disproportionately reduced the time available to perform these mental
operations, thereby adding new and more complex cognitive tasks. A concept
crucial to the evaluation of modern man-machine systems is that of the
resulting implications of loading and overloading the cognitive
capabilities of the human systems component, namely the measurement of
mental workload. ( Abbreviation abstract )
