A futuristic AI-powered desktop controller that allows you to manage system volume, screen brightness, and act as a virtual mouse using real-time hand gestures. Built with Python, OpenCV, and MediaPipe.

• Multi-Mode System: Seamlessly switch between different control modes using keyboard triggers.
• 🔊 Volume Control (Mode V): Adjust system volume by pinching your thumb and index finger.
• ☀️ Brightness Control (Mode B): Control screen brightness with the same intuitive pinch gesture.
• 🖱️ Virtual Mouse (Mode M): Move your cursor using your index finger and click by pinching.
• 📸 Quick Screenshot: Press S to take an instant screen capture of your workspace.
• Interactive UI: Real-time visual feedback, FPS counter, and mode indicators drawn directly on the webcam feed.

• Python 3.x
• OpenCV (cv2) - Computer vision and webcam frame processing
• MediaPipe - Real-time advanced hand tracking and landmark detection
• Pycaw & Comtypes - Windows system audio manipulation
• Screen-Brightness-Control - Multi-monitor brightness adjustment
• PyAutoGUI - Virtual mouse movement and automated clicks
• NumPy & Math - Coordinate interpolation and distance calculation
