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.
