Modern Hand Gesture to Watch YouTube

Computer Vision Project to Control YouTube Using Hand Gestures

Getting Started

This guide will help you set up and run the Hand Gesture Control program on various operating systems (macOS, Linux, Windows).

Prerequisites

• Python 3.7 or higher(Maximum at 3.10)
• pip (Python package manager)
• A working camera with proper permission granted

Automatic Setup (Recommended)

1. Clone the repository:

   git clone https://github.com/bagaspra16/vision-python.git
   cd vision-python

2. Run the setup script:

   bash setup.sh

   Optional for Linux/macOS users:

   chmod +x setup.sh && ./setup.sh

   This script will:

   • Create a virtual environment (gesture_env)
   • Activate the virtual environment
   • Install all dependencies from Requirements.txt
   • Perform additional OS-specific setup (e.g., install alsa-utils on Linux)

3. Activate the virtual environment (if not already):

   • macOS/Linux:

     source gesture_env/bin/activate

   • Windows (Git Bash/PowerShell):

     source gesture_env/Scripts/activate

4. Run the program:

   python3 main.py

Manual Setup (Alternative)

1. Create and activate the virtual environment:

   python3 -m venv gesture_env
   source gesture_env/bin/activate  # macOS/Linux
   # or
   source gesture_env/Scripts/activate  # Windows

2. Install all dependencies:

   pip install --upgrade pip
   pip install -r Requirements.txt

Controls & Usage

Once the program is running, you can control your computer using hand gestures in front of the camera:

• Open all fingers of the right hand: Open browser (YouTube)
• All fingers of right hand open: Move the mouse cursor
• Only the index finger extended: Left click
• Distance between both hands: Control volume (farther = increase, closer = decrease)
• Make a fist with the right hand for 5 seconds: Exit the program
• Move hand up/down on the screen: Auto-scroll the page
• Press 'q' key on keyboard: Quit the application

Notes:

• Make sure the camera is granted access in your OS settings.
• On Linux, ensure alsa-utils is installed for volume control to work.
• On macOS, you may need to allow camera and input control access via System Preferences.

Troubleshooting

• If the camera is not detected, ensure it's not being used by another application.
• If gestures aren't responsive, ensure proper lighting and that your hand is clearly visible to the camera.
• For library-related errors, make sure all dependencies are installed in the virtual environment.

This program uses OpenCV, MediaPipe, pyautogui, and other libraries to detect hand gestures and control the computer cross-platform.
