Physiological Markers of Vigilance Variation in a Supervisory Task
Résumé
Many recent studies show that physiological markers can support the assessment of cognitive states such as human attention or vigilance variation. In the perspective of new cockpit or future products that are evaluated in a more ecological simulation context, we investigate which and how such physiological metrics could complete the often used classical methods such as subjective ratings or direct observation. Before assessing their robustness in a more ecological environment, we present the results of two experiments aiming to select the set of relevant metrics: A psychomotor vigilance task classically used in the study of vigilance and a second task that combined an alarm detection task and a supervisory task. Global results show that the combination of ECG and eye-tracking indicators is a promising solution for the investigation of pilot vigilance decrement in a cockpit simulator.
