🎯 Usage

1. Install Dependencies

# Minimum (for testing)
pip install numpy

# Full system
pip install numpy websockets opencv-python google-genai

2. Choose Your Path

Option A: Test System (Recommended First)

python test_production_system.py

No hardware required. Tests:
- Database operations
- Template training
- Gesture recognition
- Export/import
- Auto-recovery

Option B: Full Training System

python run_training_system.py

Requires:
- Phone with Sensor Logger app
- Gemini API key (optional, for video)

3. Train Your First Gesture

# Import production components
from dj_agent.gesture_control import (
    GestureDatabase,
    GestureRecorder,
    GestureRecognizer,
)

# Create database
db = GestureDatabase("./gesture_database")

# Train template from 15+ samples
template = db.train_template("swipe_right", run_cross_validation=True)

# Recognize gestures
recognizer = GestureRecognizer(database=db)
result = recognizer.recognize(sensor_features)

1. Record 15+ samples (3 min)
2. Train template (<1 sec)
3. Practice until >85
4. Deploy to DJ system

Sample Training Output

📊 Progress for 'swipe_right':
   Current samples: 15/15
   Remaining: 0

🎓 Training template...
✅ Trained template for swipe_right

🔧 Configuration

Database Settings

GestureDatabase.MAX_BACKUP_COUNT = 10          # Keep last N backups
GestureDatabase.BACKUP_RETENTION_DAYS = 30     # Delete old backups
GestureDatabase.AUTO_BACKUP_INTERVAL = 300     # Backup every 5 min

Recognizer Settings

recognizer = GestureRecognizer(
    confidence_threshold=0.7,    # 0-1
    enable_caching=True,          # Template caching
    enable_calibration=True,      # Confidence calibration
)

# Adjust feature weights
recognizer.feature_weights['gyro_direction'] = 2.0  # Critical
recognizer.feature_weights['accel_peak_x'] = 1.5     # High

Recorder Settings

recorder = GestureRecorder(
    auto_save=True,                          # Crash recovery
    session_dir="./recording_sessions",      # Recovery location
)

GestureRecorder.MIN_SENSOR_READINGS = 10     # Minimum data
GestureRecorder.SENSOR_QUALITY_THRESHOLD = 0.8  # Quality bar

---

🐛 Troubleshooting

Phone Not Connecting

# Check connection
telnet <computer-ip> 8765

# Check firewall
sudo lsof -i :8765

### Low Recognition Accuracy
1. Record more samples (20+ recommended)
2. Remove outliers (automatic in production)
3. Use Practice Mode to identify weak features
4. Lower confidence threshold temporarily

Database Issues

# Check database health
python -c "from dj_agent.gesture_control import GestureDatabase; \
  db = GestureDatabase(); \
  print(db.get_stats())"

# View backups
ls gesture_database/backups/

Read: [PRODUCTION_DEPLOYMENT_GUIDE.md](./PRODUCTION_DEPLOYMENT_GUIDE.md) for complete troubleshooting.
