Blinks, Saccades, and Fixation Pauses During Vigilance Task Performance: 1. Time on Task.

Abstract

In the future, operators of complex equipment will spend more time monitoring computer controlled devices rather than having hands-on control of such equipment. The operator intervenes in system operation under "unusual" conditions or when there is a computer malfunction. The latter occurs relatively seldom. The operator's task thus becomes a "vigilance" task, one requiring attention to monitoring equipment with little need for action. An individual's ability to maintain vigilance is easily compromised, with time-on-task (TOT) a major detractor of performance. The question asked in this research was: Can gaze control measures be used to reflect, and hopefully to predict, periods of impaired vigilance?
