| الوصف: | This paper describes how a simple workload measure obtained every 2-3 minutes during the evaluation of a prototype command and control console can be used to develop an operator's workload profile as a function of other system parameters, such as track density on the tactical plot, and task loading. If system measures can be monitored regularly, functional models of operator workload can be derived, and workload levels can be interpolated to provide near-continuous workload estimates every 15-30 seconds. The resulting workload profiles can be used to identify conditions that result in potential operator overload. Profiles from several operators may be used to study team workload distribution and to derive more efficient work allocation strategies. Also discussed in the present work is how the simple unidimensional workload measure relates to multidimensional measures that differentiate between mental demand, physical demand, frustration, and other aspects of work. Multidimensional measures require more extensive reporting and are thus not suitable for administration during system testing. A common multidimensional scale, the NASA Task Load Index (TLX), was administered at the conclusion of the each evaluation session. Regression analysis revealed that the 90th percentile from the distribution of unidimensional workload estimates related to the NASA-TLX dimensions of mental effort and temporal demand in a group of 20 operators. These findings indicate that near-continuous workload profiles may be built from simple subjective workload estimates combined with system-state information, and that the workload estimates can be linked to specific behavioral dimensions as captured by more complex workload assessment scales. iii iv CONTENTS EXECUTIVE SUMMARY . |
