During the activation process of a Glass device, Google decided to uses a QR Code as a programming helper. You can try it out by your own when you have a
Google account. Use the url: https://glass.google.com/setup
and click through the different steps until you reach the input field where you asked for a Network Name. Just put any name here and the next window generates a QR Code with the name of the given input. A really smart and easy way to program a device which does not have a lot of control buttons.
