ABSTRACT
The development of biobehaviorally based technologies that objectively provide on-line measures of alertness and drowsiness has recently undergone intensified activity due to demands imposed by the somewhat unrealistic expectation that humans can work and maintain performance continuously throughout the 24-hour day. Technology developments in the area of continuous detection of fatigue, while people perform (e.g., driving), have focused on sensors and monitors that can detect drowsiness and hypovigilance. Advances in electronics, optics, data-acquisition systems, algorithm developments, and many other areas have made it far more likely that the goal of an affordable, unobtrusive drowsiness detection system will be incorporated and implemented in various operational environments in the near future.
