Abstract: A system for monitoring operator alertness. The system includes a sensor for detecting a head position property of a head of an operator and a controller in operative communication with the sensor. The controller is configured to collect a first plurality of time points of the head position property of the head of the operator, determine a baseline of the head position property of the head of the operator based on the first plurality of time points, collect a second plurality of time points of the head position property of the head of the operator, determine an operating condition of the head position property of the head of the operator based on the second plurality of time points, and evaluate the alertness of the operator based on a comparison of the operating condition to the baseline to identify a period of head stillness.
