Minuum keyboard on a Smart Watch

The smart watch as an output device is pretty obvious, but this is really interesting tech to make it a viable input device as well.

The Minuum team made a really impressive IndieGoGo video a while back[1], they quickly got the Android version of the keyboard onto the Play store[2], and they're still continuing to impress! Great work, keep it up.
