Trucking companies are equipping drivers with wearable monitors that check for signs of fatigue, and notify them when it’s time to pull over and rest.
Optalert makes glasses that measure eye-blinks with a light-emitting diode monitor, and displays those measurements in real time on a dash-mounted device with alarms and alerts.
Meanwhile, a headset by the software firm Maven Machines detects the angle of the driver's gaze, mirror checks, head bobs and jerks, and other signs of drowsiness. The device uses software that pulls data from internal accelerometers, onboard sensors, and global-positioning system data from cellphone towers.
Some products attempt to predict drowsiness, and fatigue management technology developer Fatigue Science sells software that analyzes sleep data from wearables and helps to boost drivers' awareness of fatigue risk ahead of time.
