Supervisory control environments, such as the NASA control room can induce high workload
levels in situations where a single error is capable of costing millions of dollars. An …

Many methods and models have evolved in recent years with the objective to improve our
ability to predict and measure workload, based on the desire to assure operators can …

Information regarding properties of workload assessment techniques as applied to multi-task
environments is reviewed in this chapter. Workload assessment in multi-task environments …

This report documents the results of an analysis of the scientific literature on operator
workload. It begins with an extensive discussion of the concept and definitions of operator …

Workload measurement techniques vary with respect to certain properties that determine the
utility of a technique for individual applications. Two particularly critical properties are the …

The concept of workload and its relationship to performance is introduced in this chapter.
Four categories of workload measurement techniques (ratings, primary and secondary task …

It has been stated for many years that workload is an important problem area for man-
machine-systems research and development. In order to evaluate alternative solutions in …

The Subjective Workload Assessment Technique (SWAT) has been used to assess mental
workload in a variety of situations. As with subjective techniques generally, use of SWAT has …

Assessment of subjective workload is becoming increasingly important in the evaluation of
human-machine systems. Two popular methods were compared:(1) the Subjective …
