Driver fatigue is known to be one of the leading causes of traffic accidents, which implies that prevention and early detection of driver fatigue could go a long way to reducing the incidence of car crashes.
A team of researchers and engineers from Washington State University Spokane have developed a steering wheel system that detects fatigue and drowsiness using inexpensive electronics.
The system works on the basis that variability in steering wheel movement is a great indicator fatigue. Relatively small amounts of steering wheel variability predict the onset of driver fatigue, before things get to the point where a car is drifting and swerving out of its lane.
This ingenious and potentially life-saving steering wheel system could be built into new cars or easily installed as an after-purchase accessory.
