Steps to Run the App

Prerequisites

• The app is designed for Python 3.8 and is optimized for the NVIDIA Jetson Nano or a Linux environment.
• Ensure that the default camera is configured and ready for use.
• Important: You will need two terminal windows running simultaneously:
  • One for starting the Bluetooth server and ensuring a Bluetooth device is connected.
  • One for running the application.

Steps to Set Up the Environment

1. Create a virtual environment with Python 3.8:

   python3.8 -m venv venv
   source venv/bin/activate

2. Install the required dependencies:

   pip install -r requirements.txt

   Alternatively, manually install the required imports:

   pip install numpy~=1.24.3 opencv-python~=4.10.0.84 mediapipe~=0.10.9 pynput~=1.7.7 tensorflow~=2.13.0 dbus-python~=1.3.2 keyboard==0.13.5 evdev==1.7.1 PyGObject==3.50.0 pycairo==1.27.0

Steps to Run the Bluetooth Server

1. In the first terminal:

   • Ensure the default camera is configured and operational.

   • Copy the D-Bus configuration file to the system directory:

     sudo cp ./src/jetson/bt_utils/org.yaptb.btkbservice.conf /etc/dbus-1/system.d

   • Disable the Bluetooth service:

     sudo systemctl disable bluetooth

   • Stop the Bluetooth service:

     sudo systemctl stop bluetooth

   • Start the Bluetooth server by running the script:

     sudo python start_bt_server.py

2. Verify that the Bluetooth device is connected and ready.

   • The app uses dbus-python, so your Bluetooth device should be properly paired and connected to the device where the key mappings will be sent.

Steps to Run the Application

1. In the second terminal:

   • Activate the virtual environment:

     source venv/bin/activate

   • Navigate to the source directory for Jetson:

     cd src/jetson

   • Run the application:

     python app.py

Notes

• The Bluetooth functionality was developed with the NVIDIA Jetson Nano in mind. Compatibility with other environments is not guaranteed.
• Ensure both terminal windows remain open and running while the application is in use.
