Methods and apparatus for monitoring fatigue and notifying an individual are described. The individual may be an operator of a vehicle equipment or machine a student or other person that may experience fatigue. Motion of the individual is monitored to detect a predescribed motion in response to a stimulus to first determine a base responsiveness profile. Afterwards a current responsiveness profile is determined based on a prescribed motion in response to a stimulus and if the current responsiveness profile exceeds a predetermined threshold of the base responsiveness profile a notification is issued to the individual and optionally another person such as an employer teacher or parent.
