Abstract

Workload and performance are critical factors in the evaluation of man-machine systems. Systems are designed with certain performance requirements in mind, and the attempt to meet these requirements imposes a certain workload on the human operator. Although a precise definition of mental workload has proven elusive, we must nevertheless deal with this concept because we feel intuitively that such a phenomenon exists, and is an important limitation to both system performance and operator acceptance.
