🚗 NeuroDrive: Stay Awake. Stay Alive.

The problem: Drowsy drivers often close their eyes for 2–3 seconds without realising it. At highway speed, that’s enough to cause a crash, and most cars have nothing to warn them.

Our solution: NeuroDrive watches the driver’s face through a normal laptop webcam and sounds a loud alarm before drowsiness becomes dangerous. No extra hardware, no installation, and no video ever leaves the device. The AI runs fully inside the browser.

How it works

1. Webcam streams live video in the browser
2. MediaPipe Face Landmarker maps 468 points on the driver’s face every frame
3. We calculate six real signals from those points:
   • Eye closure (EAR): eyes counted as closed when the Eye Aspect Ratio drops below 0.21
   • Blink rate: blinks per minute
   • Yawns: mouth stays wide open for over 1 second
   • PERCLOS: % of the last 60 seconds with eyes closed
   • Head nods: sudden forward drop of the head
   • Looking away: face turned away from the road
4. These combine into a Drowsiness Score (0–100) and a Cognitive Load level
5. If eyes stay closed for 2 seconds or the score passes 70, a full-screen red alert appears and an alarm keeps ringing until the driver clicks “I’m Awake”

✅ How to test it (30 seconds)

1. Open the app in Chrome and click Allow for the camera
2. Sit facing the camera in good light; you’ll see your live EAR value on screen
3. Close your eyes for 2 seconds and the alarm goes off
4. Try a big yawn or nodding your head down and watch the score rise
