Abstract : Two new applications of established techniques for measuring an individual's level of stress (workload) in tracking tasks are presented. An indirect technique of measuring 'reserve capacity' is utilized in a two-axis cross-coupled compensatory tracking task. A direct psychophysiological measurement is made by recording time histories of operator pupil diameter. The level of instability in the second axis of the cross-adaptive method is shown to be related to the level of workload in the primary axis. Increased pupil diameter is shown to be similarly related to operator workload.
