Gesture Control System A real-time hand gesture recognition system that enables mouse control, volume adjustment, brightness control, and screenshot capture using hand gestures detected via a webcam. Built with MediaPipe, OpenCV, PyAutoGUI, and system-level APIs. Features

• Mouse Movement: Move the mouse cursor by moving your index finger.
• Left Click: Perform a left mouse click using a specific hand gesture.
• Right Click: Perform a right mouse click with a different gesture.
• Double Click: Perform a double click using another gesture.
• Screenshot Capture: Take screenshots with a dedicated hand gesture.
• Volume Control: Toggle and adjust system volume by holding a gesture on the left hand.
• Brightness Control: Toggle and adjust screen brightness by holding a gesture on the right hand.
• Hold-to-Toggle Control Modes: Volume and brightness controls are activated only after holding the toggle gesture for 3 seconds, preventing accidental switches.
• Visual Feedback: On-screen text displays current actions and countdown timers for toggling controls.

Folder Structure (MVC)

• model/ - Contains logic related to gesture detection, audio and brightness control.
• view/ - Contains UI related code (displaying camera feed and text overlays).
• controller/ - Handles input processing and interaction between model and view.

Notes

• Ensure your webcam is enabled and accessible.
• Volume and brightness control use Windows-specific APIs (pycaw and screen_brightness_control).
• Gestures may vary slightly based on lighting and webcam quality.
• You may need to adjust gesture thresholds for better accuracy depending on your environment.

Troubleshooting

• If volume or brightness controls do not work, verify your OS and permissions.
• For brightness adjustment, the system must support software control of the backlight.
• If the webcam feed does not appear, check your webcam connection and permissions.
