Watch the video

This project has been shared extensively across social media, and covered in the press: BBC, Verge, Mashable, Fast Co, Kottke, VentureBeat, NowThis and others

Run the demo in latest Chrome/Firefox to train the model using your own words and corresponding signs/gestures. If you have an Echo plugged in closeby, it should respond, otherwise simply play around and have fun. You will need to give permission to access your webcam and microphone.

Running the code

To use the code, first install the JavaScript dependencies by running

npm install

Then start the local budo web server by running

npm start

This will start a web server on localhost:9966.

  1. Allow permission to your webcam and microphone.

  2. Add some words you want to train on.
