ABSTRACT
The assessment of mental workload (MWL) is of crucial importance during the design and evaluation of complex systems. The construct of MWL has been investigated in a wide variety of domains, including aviation, air traffic control, military operations, driving and control room operation to name only a few. Subjective-rating MWL assessment techniques are administered either during or post-task performance and involve participants providing ratings regarding their perceived MWL during task performance. Primary and secondary task performance measures are typically used in conjunction with physiological measures and subjective workload techniques in order to measure operator MWL. The Subjective Workload Dominance Technique is a subjective MWL assessment technique that has been used both retrospectively and predictively. The participant should be presented with the Subjective Workload Dominance Technique rating sheet and asked to predict the MWL dominance of the interface under analysis.
