A computer system records eye tracking data and identifies movements in the eye tracking data to determine gaze and pupil dynamics. Eye tracking data is correlated with a current task and predetermined vigilance requirements. The system determines if the user is exhibiting an appropriate level of vigilance based on the task or is becoming fixated. When fixation is detected, the system may engage in remedial action. A task flow diagram represents the operator tasks. Interactions between the user and the instrumentation are used to estimate the probability distribution of the task the user is currently conducting. The system correlates eye tracking data and physiological data such as electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRs) to determine neuroactivity. Monitoring neuroactivity reduces the probability of a false positive for fixation.
