AI Hand-Gesture Controlled Cursor with OAK-D Lite

This system integrates advanced AI capabilities, including a machine learning algorithm running on-device, to allow users to control their computer cursor through hand and gesture tracking, leveraging Google's MediaPipe and the OAK-D Lite camera's processing.

Features

• Control the cursor with hand gestures.
• Different gestures for moving, clicking, and scrolling.
• Efficient processing on OAK-D Lite's onboard chip.
• Intuitive, natural human-computer interaction.

Installation

To install the necessary dependencies, ensure you have Python 3 and pip installed on your system. Then run the following commands:

python3 -m pip install -U pip
python3 -m pip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ depthai
pip install -r requirements.txt

Make sure your OAK-D Lite camera is connected to your computer before proceeding.

Usage

The system recognizes specific hand poses to control the cursor:

• Move: FIVE pose (open hand, move around freely)
• Click: FIST pose (close fist)
• Scroll: PEACE pose (index and middle finger together, move up and down)

Running the Application

1. To run the application, use the following command:

   python3 mouse_controller.py

   The system will start in headless mode by default, with no display output.

2. To enable a real-time rendering of the hand tracking, use the -r flag:

   python3 mouse_controller.py -r

   This will open a new window showing the live hand tracking process.

Ensure your hand is in the view of the OAK-D Lite camera, and the system will track your hand movements, interpreting them to control the cursor accordingly.
