Cursor Movement using Hand Gesture

Overview

This project enables intuitive control of your computer's mouse cursor using hand gestures captured via a webcam. By leveraging computer vision techniques, the system detects hand landmarks and translates specific gestures into cursor movements and click actions. This offers an alternative, hands-free interaction method for various applications.

Features

• Real-time Hand Tracking: Utilizes MediaPipe for robust and accurate hand landmark detection.
• Gesture Recognition: Identifies specific hand poses to control cursor movement and clicks.
• Virtual Cursor Control: Move the mouse pointer simply by moving your hand.
• Virtual Clicks: Perform left-clicks , right-click, double-click, with a designated hand gesture (e.g., two fingers ,closed thumb and index finger).
• Adjustable Sensitivity: Customize cursor movement speed and gesture detection thresholds.
• Cross-platform (potentially): Written in Python, making it adaptable to different operating systems.

How it Works

The core of the project involves:

1. Webcam Input: Captures live video feed from your webcam.
2. Hand Detection and Landmark Extraction: The MediaPipe Hands model processes each video frame to detect hands and extract 21 3D hand landmark coordinates for each detected hand.
3. Gesture Interpretation:
   • Cursor Movement: The coordinates of a specific finger (e.g., the tip of the index finger) are used to map to the screen's coordinates, thereby controlling the cursor's position.
   • Click Detection: The relative positions of multiple finger landmarks (e.g., the distance between the thumb tip and index finger tip) are monitored to detect a "pinch" or "click" gesture.
4. PyAutoGUI Integration: The pyautogui library is used to programmatically move the system cursor and perform clicks based on the interpreted gestures.

Here's an example of hand landmark detection in action:

Installation

Prerequisites

• Python 3.x
• Webcam

Steps

1. Clone the repository:

   git clone [https://github.com/your-username/cursor-movement-hand-gesture.git](https://github.com/your-username/cursor-movement-hand-gesture.git)
   cd cursor-movement-hand-gesture

2. Create a virtual environment (recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows: `venv\Scripts\activate`

3. Install the required libraries:

   pip install mediapipe opencv-python pyautogui

Usage

1. Run the script:

   python main.py  # Or whatever your main script is called

2. Webcam Feed: A window will pop up displaying your webcam feed with hand landmarks overlaid.
3. Control:
   • Move your hand to move the cursor.
   • Perform a specific gesture (e.g., pinching your thumb and index finger) to perform a left-click.
   • (Add more specific gesture descriptions if your project has them, e.g., "Raise your middle finger to right-click").
4. Exit: Press q (or Esc) to quit the application.
