Early praise for Programming Google
Glass
Eric’s writing captures the spirit of Glassware development with honesty, wit,
and charm—peppered with a healthy dose of insider tricks and techniques for
quickly building effective wearable computing services that coders of all levels
will appreciate.
→ Jason Salas
Coauthor, Think for Glass: Discover, Design, Develop
This insightful book opened my eyes to the potential of Google Glass in a big
way. Glassware is going to be huge, and this book gives you the tools to make it.
→Jim Wilson
Author, Node.js the Right Way
A great read and learning resource. You start with a small project and build it
into a full-fledged Glassware application, learning all about the Mirror API
along the way.
→Steven Mitchell
Glass Explorer
I really enjoyed your book; you successfully convinced me to buy Glass and
start learning as much about it as I can. It’s not like the tech is going to disappear
if I ignore it!
→Marissa Anderson
Principal Developer, Electrozoic
This is a great introduction to the Google Glass Mirror API. Any serious Google
Glass developer will want to get a copy of this book.

Acknowledgements
All books, even short ones like this, require efforts that extend far beyond a
single author. Although I get to put my name on the cover, I want to thank
everyone who helped turn a collection of drafts and ideas into a book we all
hope you’ll enjoy.
Thanks first go to my indefatigable editor, Jackie Carter. Thanks, too, to
Susannah, Andy, Dave, and the rest of the crew at Pragmatic for keeping this
ship sailing straight.
I’m thrilled to thank my eagle-eyed friend Jim Wilson, and the piles of notes
from a cadre of talented Glass Explorers: Jason Salas, Steven Mitchell, Marissa
Anderson, Mark Billinghurst, Elmer Thomas, and Rahul Ravikumar.
Finally, thanks to my patient wife Noelle for enduring another book, and a
preemptive thanks to Miss Wiggles for tolerating the next one.

Preface
Google Glass is the new wearable computer that everyone is talking about. Not
only does Glass offer a head-mounted optical display and touch interface, but
it’s also programmable in two ways: by creating native applications using the
Glass Development Kit (GDK), and by programming Glassware (Glass
applications) using the HTTP-based Mirror API. This book is about the latter.
You’ll get a glimpse of what Glass is and what it is not, and how users can
interface with Glass. Then you’ll learn how to develop a Glass application fast,
by using the Mirror API to manipulate timeline cards and menus, track a Glass’s
geolocation, create rich interactions by responding to user inputs, and capture or
serve user images and videos. You’ll see how to properly design new Glassware
or update existing applications to become Glassware. This is the book to read if
you want a shortcut to this brave new world.
