🚘 SARATHI – Unified Attention Monitoring for Transportation

"A moment’s lapse. A lifetime lost. SARATHI watches, warns, and saves."

---

📍 Overview

SARATHI is a real-time AI-based driver and pilot attention monitoring system that detects drowsiness, unsafe posture, and inattentiveness using only a single webcam. It serves as a digital co-pilot, ensuring that no fatigue-related accident goes unnoticed.

Developed during Hack4Bengal 4.0 – Eastern India's Largest Hackathon, SARATHI addresses one of the deadliest causes of transport-related deaths — fatigue.

🧪 Technical Workflow

SARATHI performs attention analysis using:

• 👁 Eye landmarks to detect prolonged closure or gaze shifts
• 🧠 Head pose (pitch, yaw, roll) to monitor orientation
• 🧍 Posture deviation using shoulder & spine angles

🧠 If any threshold is crossed:

• Screenshot is captured
• Audio alarm is triggered
• Visual status bar updates on Streamlit UI

🧗‍♂ Challenges Faced

• ⚠ Real-time processing without GPU
• 🌙 Handling low-light conditions
• ❗ Ensuring accuracy while minimizing false alarms
• 📐 Angle-sensitive posture detection
• 🧠 Calibrating thresholds across multiple face orientations

🌱 Future Enhancements

• 📷 Dual camera setup (side + front view) using IoT (e.g., Raspberry Pi)
• 🧘 User posture calibration on startup for custom thresholds
• ✋ Gesture-based alert dismissal using hand detection
• 🚨 SOS Trigger: Auto-message if alert persists beyond limit
• 🌒 Night mode via IR camera support

🕉 Why the Name "SARATHI"?

In ancient Indian tradition, SARATHI means “charioteer” — the one who safely drives the warrior through chaos.
In our context, SARATHI acts as a modern digital guide, monitoring attentiveness, preventing fatigue-induced danger, and saving lives through intelligence.
