Drowsy driving kills thousands of people in the United States each year. We’ve all been there: You are driving down a boring interstate highway at night. You start to nod off and, just when you about to enter la la land, you “snap out of it” and clutch the wheel, your heart racing. Scary, huh? And you were one of the lucky ones. Other drivers, succumbing to the sirens of sleep, crash and burn.
But a new device being developed may keep drivers like you awake and save your life. Here’s how it works:
A Bluetooth headset fits on one ear and points an infrared sensor toward the eye to detect blinking. (See photo). The driver’s blinking frequency indicates drowsiness. The data is transmitted by Bluetooth to a smartphone. If the sensor detects drowsiness, the headset vibrates, flashes and beeps to alert — and awaken — the sleepy driver.
