An eye tracking device that follows a driver’s eye movements could be in your driving future. The device, designed to monitor a driver’s eye movements and warn of inattention or driver fatigue can monitor a driver’s eyes, even through sunglasses.

Similar eye tracking devices have been talked about for quite a few years now but this one seems to have a track record. Developed by a company called Seeing Machines in Australia, their equipment has been used for some time and is currently installed in up to 4,000 delivery vehicles and heavy mining machines. Their use in mining equipment, it is claimed, has led to a 70 percent decrease in driver fatigue and distraction.

For cars, the company has developed a small eye tracking detector designed to fit easily into a car’s dashboard. It’s designed to work in conjunction with advanced driver assistance systems such as automatic braking and lane departure systems. If the system detects that a driver isn’t paying attention to the road or is fatigued, it can give an audible warning or vibrate the seat to bring the driver’s attention back to the road.

The company also sees the systems being used in aircraft cockpits and simulators, and working environments where strict attention to computer and machinery consoles is necessary.

They list Ford, General Motors, and Toyota as partners so it looks as if the auto industry is actively pursuing this technology for future applications in automobiles.
