• ✋ Control system volume by changing the distance between your thumb and index finger
• 🔊 Visual feedback for volume level on screen
• 🧠 Intuitive gesture-based interface

---

📦 Dependencies

Install the required libraries:

pip install opencv-python mediapipe numpy pycaw comtypes

Note: pycaw only works on Windows.

🚀 How to Run

1. Clone the repository:

git clone https://github.com/Yamii07/volume-controller-hand-gestures.git
cd volume-controller-hand-gestures

2. Run the script:

python volume_control.py

3. Show your hand to the webcam and pinch your thumb and index finger to adjust the volume.

🧠 How It Works

• MediaPipe detects hand landmarks in real time.
• Calculates the distance between landmark 4 (thumb tip) and landmark 8 (index finger tip).
• Maps that distance to a system volume range (0% - 100%).
• Adjusts volume using pycaw on Windows.
