Guardian Optical Technologies announced it has added the position of a driver's head to the safety elements the company's advanced "All in One" sensor can detect inside the cabin of an automobile.

The National Highway Traffic Safety Administration (NHTSA) reports drowsy driving claimed 824 lives in the U.S. in 2015. The AAA Foundation for Traffic Safety estimates that 21% of fatal motor vehicle crashes involve driver fatigue. In 2016, 3450 people were killed in motor vehicle crashes involving distracted drivers, and 9% of fatal crashes in 2016 were reported as distraction-affected crashes.

"The position of a driver's head is an integral part of understanding whether the driver is paying attention to the road while also indicating if he or she is drowsy," said Gil Dotan, CEO of Guardian Optical Technologies

Guardian's standalone automatic sensor system is built from the ground up to work with automotive hardware and software, including all built-in safety systems, such as seatbelts and airbags. Drivers are constantly kept aware of conditions and people in their cars, allowing them to sidestep dangerous human error, including unintentionally leaving infants behind in the car.

Guardian combines video image recognition (2D), depth mapping (3D), and optical micro- to macro-motion analysis to constantly scan and track occupants and objects anywhere in the vehicle, using low-cost, automotive-grade components. The sensor identifies the location and physical dimensions of everyone in the car, distinguishing people from objects. By detecting micro vibrations, the system can register, in some cases, a presence even without a direct line of sight.
