Google Glass is the first large-scale effort to bring optical wearable computers to the marketplace. It’s unlikely to be the last. Glass is a head-mounted display with many of the features of a smartphone (view screen, audio, microphone and speech recognition, camera, geolocation, touch interfaces) and runs on the Android operating system. Any developer with experience programming web services or smartphone applications need only make a short leap in their user experience sensibilities and learn a few new tools to program Google Glass. We demonstrate the Google Glass user interface and explain how to use the two development kit options—the Mirror API for web service-based development and the GDK (Glass Development Kit), which is a small superset of the standard Android Development Kit. Attendees receive a copy of Redmond’s Programming Google Glass, published by Pragmatic Programmers.
