How can we do?

Step 1: Camera
non-contact infrared camera–capture human eyelid and retina status

Step 2: Algorithm
Analyze the driver’s fatigue status according to PERCLOS algorithm.

Step 3: Alarm
Alert the driver by light and voice alarm if eyes not been detected in 2 seconds, well before they fall asleep at the wheel.

Step 4: Vibration
What can I do if the voice can’t wake me up? Don’t worry, we have vibrate here. Vibration is more shocking than voice alarm, wake up the drowsy driver immediately. Vibration is a silent alarm, wake up the driver only, instead of the passenger.

Step 5: Center Monitor
