• 🖌️ Draw in mid-air using hand gestures
• 🎨 Multiple color options (Blue, Green, Red, Yellow)
• 📏 Adjustable brush sizes
• 💫 Real-time hand tracking
• 🔄 Canvas clearing option
• 🖼️ Smooth drawing experience
• 📸 Live webcam integration

🛠️ Technical Requirements

Hardware

• Webcam (Optional)
• Computer with Python support

Software Dependencies

pip install opencv-python
pip install mediapipe
pip install numpy

🚀 Installation & Setup

1. Clone the repository

git clone https://github.com/Vinandra-Adam-Saputra/AirCanvas-VirtualDrawing.git
cd AirCanvas-VirtualDrawing

2. Install dependencies

3. Run the application

python virtual_paint.py

🎮 Controls & Usage

Hand Gestures

• ☝️ Index Finger Up + Middle Finger Down: Activate drawing mode
• ✋ Other Positions: Pause drawing

Keyboard Controls

• q - Quit application
• c - Clear canvas
• b - Switch to blue color
• g - Switch to green color
• r - Switch to red color
• y - Switch to yellow color
• + - Increase brush size
• - - Decrease brush size

💡 How It Works

Hand Detection

• Uses MediaPipe Hands for accurate hand landmark detection
• Tracks 21 different points on your hand
• Focuses on index finger tip for drawing

Drawing Logic

1. Initialization

   • Sets up video capture
   • Creates empty canvas
   • Initializes color options and brush settings

2. Hand Tracking

   • Detects hand in frame
   • Identifies finger positions
   • Determines drawing mode based on gesture

3. Drawing Process

   • Tracks index finger movement
   • Creates continuous lines when drawing
   • Maintains smooth line quality

🛠️ Customization

Adjusting Detection Sensitivity

self.hands = self.mp_hands.Hands(
    max_num_hands=1,
    min_detection_confidence=0.7,
    min_tracking_confidence=0.7
)

Adding New Colors

self.colors = {
    'blue': (255, 0, 0),
    'green': (0, 255, 0),
    'red': (0, 0, 255),
    'yellow': (0, 255, 255)
    # Add your custom colors here
}
