📖 Usage Guide

⚠️ IMPORTANT: You MUST complete these steps in order! The system will not work without proper setup.

🎯 Step 1: Train Your Personal Baseline (REQUIRED)

This step is MANDATORY before using the real-time predictor!

cd RealTime_Panic_Detector
python realtime_baseline_trainer.py

What happens:

  1. 🔌 Connects to Arduino via serial port
  2. 📊 Collects 5 minutes of calm, relaxed sensor data
  3. 🧮 Calculates YOUR personal normal levels
  4. 💾 Saves baseline to medical_baselines.pkl

Requirements:

  • ✅ Stay calm and relaxed during collection
  • ✅ Ensure good sensor contact
  • ✅ Avoid movement or stress
  • ✅ Complete the full 5-minute collection

Why this is required:

  • 🎯 Creates YOUR personal baseline (heart rate, EDA, breathing, etc.)
  • 🚫 Without this, the system won't know YOUR normal levels
  • ⚠️ The real-time predictor will fail without a personal baseline

🤖 Step 2: Prepare Machine Learning Models (REQUIRED)

Choose ONE of these options:

Option A: Use Pre-Trained Models (Recommended for beginners)

The repository includes pre-trained models in the models/ folder. These are ready to use!

# Models are already included in the repository
# No additional training needed
ls models/
# You should see: medical_ensemble_model.pkl, medical_random_forest_model.pkl, etc.

Option B: Train Your Own Models (Advanced users)

# Go back to main directory
cd ..

# Train new models with your data
python medical_panic_trainer.py

What happens:

  1. 📚 Loads WESAD dataset (if available)
  2. 🧠 Trains 6 different ML models
  3. 📊 Evaluates model performance
  4. 💾 Saves trained models to models/ folder

Requirements for Option B:

  • ✅ WESAD dataset in the correct location
  • ✅ Sufficient computational resources
  • ✅ 2-3 hours for training

🚨 Step 3: Start Real-Time Monitoring

Now you can use the real-time predictor!

cd RealTime_Panic_Detector
python realtime_panic_predictor.py

What happens:

  1. 📚 Loads YOUR personal baseline from Step 1
  2. 🤖 Loads trained models from Step 2
  3. 🔄 Starts continuous 30-second monitoring windows
  4. 🧠 Runs ML prediction on each window
  5. 🏥 Validates against clinical thresholds
  6. 📱 Displays real-time alerts and status

Prerequisites:

  • ✅ Personal baseline must be created (Step 1)
  • ✅ Trained models must be available (Step 2)
  • ✅ Arduino must be connected and working

📊 Step 3: Monitor Results

The system displays real-time information:

📊 14:30:25 - ✅ Normal stress levels - You're doing well!
   🤖 ML Probability: 15.2%
   🏥 Clinical Probability: 8.5%
   🎯 Combined Probability: 12.8%
   🚨 Alert Level: NORMAL

🎮 Advanced Usage

Training Custom Models

# Train new models with your data
python medical_panic_trainer.py

Testing Without Hardware

🚨 Common Setup Issues & Solutions

❌ Error: "No baseline found for user"

Problem: You tried to run realtime_panic_predictor.py without creating a baseline first.

Solution:

# You MUST run this first:
cd RealTime_Panic_Detector
python realtime_baseline_trainer.py
# Complete the 5-minute training session
# Then run the predictor:
python realtime_panic_predictor.py

❌ Error: "Models not found"

Problem: The system can't find the trained ML models.

Solution:

# Option 1: Use pre-trained models (recommended)
# Make sure the models/ folder exists with all .pkl files

# Option 2: Train your own models
cd ..
python medical_panic_trainer.py
cd RealTime_Panic_Detector
python realtime_panic_predictor.py

❌ Error: "Arduino connection failed"

Problem: Can't connect to Arduino for baseline training.

Solution:

  1. Check Arduino is connected via USB
  2. Note the COM port (e.g., COM3, COM4)
  3. Update the port in the script if needed
  4. Ensure Arduino code is uploaded

❌ Error: "Insufficient valid data for baseline calculation"

Problem: Not enough good sensor data during baseline training.

Solution:

  1. Ensure sensors are properly connected
  2. Stay completely still during the 5-minute session
  3. Check sensor contact (especially heart rate and EDA)
  4. Try again in a quiet, calm environment
