ABSTRACT
Design systems so they can detect when users are drowsy or asleep, and then rouse users to prevent accidents due to fatigue or drowsiness. Automobile companies and construction machinery manufacturers have tried to address the hazard of fatigued driving by developing systems that detect and rouse drowsy and asleep drivers. Falling asleep during high school math class has consequences, but ones that are not as dangerous as the sort that can occur when people fall asleep, or even become drowsy, while performing critical tasks. Pilot and air traffic controller fatigue is also a recognized problem. This is reflected in US Federal Aviation Administration rules established in 2011, which limit working hours for pilots. On-duty time is limited to 9-14 hours depending on the flight route and when the pilot’s day begins. Pilots must also have a rest period of 10 hours before returning to duty.
