The people I&#x27;m talking about were also students, (University Hackathon).  A group of four, I want to say 2 sophomores and 2 freshmen.<p>This was 2-3 years ago, so machine learning wasn&#x27;t advanced (and even now, getting a functional NN running and trained in a weekend isn&#x27;t feasible) so they only had it recognize a small set of commands, but it could do that.
