Duel is an early prototype for an online browser based motion tracking workout game where players interact with 3d objects in a shared space and compete against each other to win. Initiated as an extension of Jason’s motion tracking exercise web app, Duel was designed to be a more welcoming and fun game for all exhibition visitors, no matter their fitness level. It also served as a big learning experience in working with WebRTC, Three.js, Websockets, and Tensorflow.js in tandem.
