🖐 Hand Gesture Controlled Shutdown

This project lets you shut down your computer using a hand gesture detected via your webcam. Built with Python, OpenCV, and MediaPipe, it identifies a specific gesture (middle finger up, others folded) and executes an immediate shutdown.

📦 Requirements

Install the required Python packages using:

pip install -r requirements.txt

The requirements.txt file contains:

opencv-python
mediapipe
numpy

🚀 How It Works

• Captures real-time hand landmarks using MediaPipe.
• Detects if:
  • Middle finger is extended.
  • Index, Ring, and Pinky fingers are folded.
• If the gesture matches, triggers a system shutdown.

⛘️ Warning: Shutdown is immediate once the gesture is recognized. Test carefully!

📋 Usage

1. Clone the repository and navigate into the project folder.
2. (Optional but recommended) Create and activate a virtual environment:

python3 -m venv venv
source venv/bin/activate  # On Linux/Mac
venv\Scripts\activate    # On Windows

3. Install the dependencies:

pip install -r requirements.txt

4. Run the script:

python main.py
or
python3 main.py

5. Allow webcam access.
6. Make the ultimate savage gesture:
   • Raise your middle finger high like you're flipping off your PC ✌️.
   • Keep the rest of your fingers tucked down like they know who's boss.
7. Watch your computer surrender and shut down immediately.
8. Press Q if you want to exit like a "civilized" human without nuking your machine.

🛠 Developer Notes

• To test without shutting down, comment shut_down_computer() and uncomment print("shutdown").
• Landmark detection follows MediaPipe's index for hand joints.

---

🧹 Extra Details

• Image Flip:

  • Makes webcam act like a mirror.

• Y-Axis for Detection:

  • In MediaPipe, y increases downward.
  • If fingertip y is higher (smaller) than the PIP joint y, the finger is pointing upward.

🧹 Author's Note

"Left # print("shutdown") commented out... because I'm cool like that. 😎"

Stay savage. 👑
