A sneak peak of the Google’s Glass Development Kit (GDK) has been released. To give a sense of the state of the Glass development ecosystem: even the official Developer preview is ‘yet to come’.
The GDK is an addition to the Android SDK and allows developers to build ‘Glassware’ that runs directly on Glass, making use of its native hardware and software functionality, including Voice, Gesture Detection and ‘Cards’. The current documentation includes information on design patterns (ensuring a consistent user experience), and best practices regarding Cards, Menus, ‘Icons and Assets’ and Writing.
I can’t wait to start experimenting with Glass as soon as possible.
