SYSTEM AND METHOD FOR USING MICROSACCADE PEAK VELOCITY AS A MEASURE OF MENTAL WORKLOAD AND FATIGUE

A system and method for determining a subject's level of fatigue. The method includes measuring microsaccadic eye movement dynamics of the subject, calculating a current microsaccade peak velocity from the measured microsaccadic eye movement dynamics, and comparing the current microsaccade peak velocity to a baseline microsaccade peak velocity. The method further includes determining the level of fatigue based on a difference between the current microsaccade peak velocity and the baseline microsaccade peak velocity.
