# Hand Tracking

Real-time hand gesture recognition using MediaPipe and machine learning. Detect and classify hand gestures from video input.

## Features

- **Real-time Hand Detection**: Detect hands in video streams using Google's MediaPipe framework
- **Gesture Recognition**: Classify hand gestures using a pre-trained machine learning model
- **Multiple Interfaces**: Choose between:
  - Standalone hand tracking with OpenCV
  - Interactive hand-controlled game with Pygame
- **Easy to Use**: Simple API for integrating hand tracking into your applications
- **Flexible**: Support for webcams and video files as input

## Installation

### Basic Installation

Install the hand tracking package:

```bash
pip install hand-tracking
```

### With Game Support

To use the hand-controlled game features:

```bash
pip install hand-tracking[game]
```

### Development Installation

For development and testing:

```bash
git clone <repository-url>
cd hand-tracking
pip install -e ".[dev,game]"
```

## Quick Start

### Hand Gesture Recognition

```python
from hand_tracking import HandTracker

# Initialize the tracker
tracker = HandTracker()

# In your video processing loop:
import cv2

cap = cv2.VideoCapture(0)
while True:
    ret, frame = cap.read()
    if not ret:
        break
    
    # Get prediction
    result = tracker.predict_gesture(frame)
    
    # Draw on frame
    frame = tracker.draw_predictions(frame, result)
    
    # Display
    cv2.imshow('Hand Tracking', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()
```

### Command Line Usage

Run the hand tracking application:

```bash
hand-tracker
```

Or use the interactive game:

```bash
hand-tracking-game
```

### Hand Tracking Game

```python
from hand_tracking import HandTrackingGame

# Create and run the game
game = HandTrackingGame(screen_width=1280, screen_height=720)
game.run()
```

## Gesture Labels

The hand tracker recognizes the following gestures:

- **Greeting**: Hi
- **Letters**: A through Y (missing C and Z in current model)

For the game, special direction gestures are used:

- **up**: Move up
- **down**: Move down
- **left**: Move left
- **right**: Move right

## Model

The package includes a pre-trained model (`model.p`) that was trained on hand landmark data. To use your own model:

```python
tracker = HandTracker(model_path='/path/to/your/model.p')
```

## Requirements

- Python >= 3.8
- OpenCV (opencv-python)
- MediaPipe
- NumPy
- Pygame >= 2.1.0 (for game features)

## API Reference

### HandTracker

Main class for hand gesture recognition.

**Methods:**

- `__init__(model_path=None)`: Initialize the tracker
- `predict_gesture(frame)`: Predict gesture from a video frame
  - Returns: `{character, landmarks, bbox}`
- `draw_predictions(frame, prediction_result)`: Draw predictions on frame

**Class Attributes:**

- `LABELS_DICT`: Mapping of gesture indices to labels

### HandTrackingGame

Interactive game using hand gestures.

**Methods:**

- `__init__(screen_width=1280, screen_height=720, model_path=None)`: Initialize game
- `run()`: Run the game loop
- `handle_gesture(predicted_character)`: Process gesture input

**Functions:**

- `run_hand_tracking(video_source=0, model_path=None)`: Run standalone hand tracking
- `main()`: Run the game (entry point)

## Troubleshooting

### Camera Not Opening

- Ensure your webcam is connected
- Check camera permissions (especially on macOS/Linux)
- Try specifying a different camera index: `HandTracker(...)`

### Poor Gesture Recognition

- Ensure adequate lighting
- Keep your hand clearly visible
- Make sure the hand is not too close or too far from the camera
- The model was trained on specific hand positions

### Import Errors

- Ensure all dependencies are installed: `pip install -e .[dev,game]`
- Check Python version >= 3.8

## Performance

- Typical latency: 30-50ms per frame on modern hardware
- Tested on: Intel i5+ / AMD Ryzen 5+, with integrated graphics
- FPS: 20-30 FPS typical
