Original Abstract Submitted
A fatigue detection and operator alert system is disclosed for detecting operator fatigue in a machine having a cab, a seat, and a joystick. The fatigue detection and operator alert system comprises an optic sensor positioned non-obstructively facing an operator and configured to output a first signal consisting of images captured of an operator; a pressure sensor configured to provide a second signal indicative of a pressure of an operator hand on the joystick; a thermal sensor configured to provide a third signal indicative of a temperature of the operator; a load sensor configured to provide a fourth signal indicative of a load of an operator foot; and a controller configured to: receive the sensor signals; detect instances of operator fatigue based on the received sensor signals during non-hauling operation; and actuate an alert device to alert the operator when instances of operator fatigue are detected.
