# 🔊 Virtual Volume Controller — OpenCV + MediaPipe Project
Control your system volume using just your **fingers** — no keyboard, no mouse, just pure gesture magic! 🖐️🤏
Built using **Python**, **OpenCV**, and **MediaPipe**, this project uses your webcam to detect finger distance and adjust the volume in real time.
## 🖼 Demo
## 🎯 How It Works
📷 Your webcam tracks your **index finger** and **thumb** using MediaPipe's hand tracking.
The distance between them determines the volume level:
- 👉✌️ **Stretch fingers wide** → Volume increases
- 🤏 **Bring fingers close** → Volume decreases
- 👈👉 **Touch both fingers** → System is **muted**
This is a simple yet powerful demo of **gesture-based human-computer interaction**!
## 🚀 Features
✅ Real-time finger tracking with MediaPipe
✅ Dynamically adjust system volume based on finger distance
✅ Mute system when fingers are touching
✅ Clean UI using OpenCV overlays
✅ Works offline (on Windows)
## 🧠 What You’ll Learn
- Hand landmark detection using **MediaPipe**
- Measuring Euclidean distance between fingers
- Mapping distance to volume percentage
- Controlling system audio using **pycaw** (Windows)
## 🛠 Setup Instructions
1. **Install the required dependencies, globlally or by creating a virtual environment:**
```bash
pip install -r requirements.txt
```
2. **Run the application:**
```bash
python volumeHandControl.py
```
## 🧰 Tech Stack & Dependencies
- Python
- OpenCV
- MediaPipe
- pycaw (for controlling system volume on Windows)
