Measuring Pilot Fatigue with ElectroOculoGraphy
DescriptionThis project assesses pilot fatigue using ElectroOculoGraphy (EOG) while operating in a prolonged aeronautical scenario simulation. Level of fatigue was defined by three EOG metrics: Blink Rate (BR), Blink Duration (BD), and positive Amplitude Velocity Ratio (pAVR).
Participants stayed awake for at least 18 hours, then completed fatigue-inducing visual tasks for up to 4 hours. EOG metrics were computed and analyzed for any correlations with fatigue development over time. The findings suggest BD appeared to be the most sensitive individual metric for assessing fatigue, displaying an upward trend where other metrics, BR and pAVR, were less consistent. Cluster analyses that considered features from each of the metrics were used to determine distinct fatigue categories, resulting in an improved categorization.
In upcoming research, a fatigue categorization model based on this cluster analysis will be tested for its ability to predict the onset and any concerning developments of operator fatigue.
