Acknowledgments

Thanks to all the wonderful people at Pearson who made what could have been an arduous and chaotic process into a clear and well-structured one. Especially to Laura Lewin, Sheri Replin, and Malobika Chakraborty for working with me through constant updates, delays, rewrites, and headaches.

My immense gratitude to all the brilliant Googlers who helped me along the way. Especially Alex Faaborg and Bryce Reid for their support, reviews, and guidance navigating the real and virtual worlds of Google. Thanks also to all the Googlers who reviewed, supported, and offered feedback: Sam Kvaalen, Joanna Kim, Pete Bradshaw, Steve Seitz, Jonathan Terleski, Adam Glazier, Brian Kehrer, Ian MacGillivray, Bruno Oliveira, Liz Markman, Michael Marconi, Nathan Martz, Rachel Inman, Marek Gorecki, Andre Le, Dominik Kaeser, Nadav Ashkenazi, Kasey Klimes, Allen Hutchinson, Yumin Zhang, Justin Quimby, Alesha Unpingco, Mathew Tizard, Doug Claar, the YouTube VR team, the Geo AR team, the Poly team in NYC, and the whole Daydream team.

Ivan Sutherland, the inventor of modern-day VR, the field is indebted to you for all of your breakthrough work. On a personal level I am exceedingly grateful for your correspondence with me regarding the Sword of Damocles and the true history of the first VR headset.

Sam Brewton Lee, whose astute insights into the AR and VR worlds inspired me and whose tireless work as technical reviewer pushed the production of this book forward. Thanks also to the other reviewers and copy editors Genevieve Berrick, Joshua Rowe, and Hendrik Schoenmaker who worked with me to make this possible. To Mike Judge for his Mini Mike’s Metro Minis open source character collection on the Unity Asset Store, used in several of the recipes in this book. James Turnbull, thanks for your sage advice on book writing, the tech industry, and knowledge of all things general.

To my parents, Jock and Judith Keene, whose support has been unyielding. Jock originally introduced me to VR at the University of Sydney, and Judith who, as the great writer in our family, imparted her extensive knowledge, insight, and copy editing skills onto this project. I could not have done it without you.

Most of all thanks to my amazing family. My wife, Kaitlin Moore, for her help reviewing, editing, and constantly supporting me for eleven exhausting months. My baby daughter, Frida, who was always available for much-needed play breaks and laughter throughout the months of writing.
