Google Glass may have been announced at last year’s Google I/O, but it didn’t get a proper introduction until this year’s I/O. Google devoted a number of sessions for the new hardware on Thursday, and Google has made some of those sessions available on YouTube.

First up is Developing for Glass with Timothy Jordan. He announced the Glass Developer Kit during this session, but there’s more than that:

By bringing technology closer, we can get it out of the way. This and other core concepts, design guidelines, UX paradigms, and APIs will be introduced as a baseline for Glass Development. Excellent examples will be shown and used to codify everything into a set of best practices. If you want to develop for Glass, this is where you start!

The other session is Voiding Your Warranty: Hacking Your Glass with Hyunyoung Sung and P.Y. Laligand:

Glass is ready for hacking! See what is possible with the hardware platform and how you can gain root access. Learn how to run your own experimental applications. Disclaimer: you’ll be stepping into uncharted and unsupported territory!
