A consortium of European companies and educational institutions is developing a technology that uses seat-located sensors to detect drivers' fatigue by monitoring their heart rate and respiration.
The system comprises three primary components -- a sensor on the inside of the seat belt's chest strap that monitors heart rate, seat back sensors that measure respiration and a signal processing unit located below the seat.
If the readings from all these sensors suggest that the driver is becoming dangerously fatigued, the system will sound an alarm or warn the driver about their fatigue levels.
The system -- dubbed 'HARKEN' or 'Heart and Respiration In-Car Embedded Nonintrusive Sensors -- has been assessed on closed tracks, and will soon be tested on open roads to see how capable it is of accurately detecting drivers' fatigue
The HARKEN System Monitors Drivers' Fatigue
