Testing the efficacy of different methods for mitigating aviation-related hypovigilance after detecting it on-line using physiological parameters

Fatigue-related decreases in vigilance (hypovigilance) and their negative effects on performance are widelyrecognized as posing a serious risk to aviation safety. In a prior Engage project, scientists at Thales Research &Technology (TRT) Canada (Quebec) collaborated with the Klein laboratory to design and conduct a researchproject in which participants performed tasks over an 8 hour period during which a variety of physiological,oculomotor and performance parameters, and self-reports of fatigue, were collected either continuously orregularly. Thales scientists then developed a mathematical model that from the physiological data could predictfatigue-related hypovigilance; a model that was successful when generalized to "new" data and that wasrecently tested in a more ecologically valid scenario (an intercontinental flight). In a followup project theDalhousie-Thales team plans to test the efficacy of mitigation measures of hypovigilance based on this model'son-line analysis of wearable data collecting during performance on a driving-like task. Thales is a world-classprovider of cockpit solutions. Their success, with the Klein laboratory, in using the data collected fromwearable devices to detect fatigue, lays the foundation for the current project in which the Klein lab willgenerate data that will allow Thales to include fatigue-mitigation strategies in their cockpit solutions.
