Volume Control 🎵

Control your computer's volume using hand gestures! This project uses computer vision to detect your hand and lets you adjust volume by pinching your thumb and index finger together.

How It Works

The app uses your webcam to:

1. Detect your hand in real-time using AI technology
2. Track your thumb and index finger positions
3. Measure the distance between them
4. Adjust volume based on that distance — closer fingers = lower volume, further apart = higher volume

Features

✨ Hand Gesture Recognition - Detects hands and finger positions
🎚️ Real-time Volume Control - Instantly adjust volume with your hand
📊 Live Feedback - See current volume percentage on screen
⚡ Performance Tracking - FPS counter for smooth operation
👋 Multi-hand Support - Can detect up to 2 hands

Requirements

• Python 3.x
• OpenCV (cv2)
• MediaPipe
• NumPy
• PyCAW (for Windows volume control)

Installation

1. Clone the repository:

git clone https://github.com/AmrEladawey/volume-control.git
cd volume-control

2. Install dependencies:

pip install opencv-python mediapipe numpy pycaw

Usage

Run the main script:

python VolumeControl.py

Then:

• Show your hand to the camera
• Bring your thumb and index finger together to lower volume
• Move them apart to increase volume
• Watch the volume percentage display on screen

Press q to quit the application.
