Ebook: Programming Google Glass: Build Great Glassware Apps with the Mirror API and GDK

The Pragmatic Programmers, 2015. - 299 p., english, ISBN: 978-1-941222-18-8, (Second Edition)Google Glass is the new wearable computer that everyone is talking about. Some people love it, some hate it, but folks can’t seem to help but talk about it. In short, Glass is a head-mounted computer with an optical display, a camera, several sensors, and a voice or touch interface. You can walk around, hands-free, check your email, watch or take videos, play games, and most anything else you can do with a smartphone. Equally important, it’s gaining traction for enterprise purposes, from fast-food restaurant employee training to use in surgical settings. You can program Glassware (Glass applications) in two ways: by using the HTTP-based Mirror API web-service, or by creating native applications using the Glass Development Kit (GDK). This book covers how to program both. You’ll get a glimpse of what Glass is and what it is not, and how users can interface with Glass. In Part One of this book 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. In Part Two you’ll learn how to shape user experience with the GDK by interacting with Glass hardware, from voice-to-text inputs, to QR code reading with the live camera, to building your own video game with fine-grained sensor inputs. You’ll see how to properly design new Glassware or update existing applica- tions to become Glassware. This is the book to read if you want a shortcut to this brave new world.
