Part 1: In this Session you will be able to get familiar with Glass capabilities, understand the Now concept and design guides for Glass in general. Part 2: In this session will dive into the Glass Developer Kit (GDK) and will practice developing for glass. The GDK is an add-on to the Android SDK that lets you build Glassware that runs directly on Glass. The session will cover how to start developing for Glass, overview about the GDK and a live demo on some GDK features.

• The Glass user interface is a virtual timeline that is comprised of 640 × 360 pixel cards.
• Users scroll through the timeline to reveal cards in the past, present, and future.
• The most recent items reside in the center of the timeline, closest to the user experience.

11. Home

The default Home card is the Glass clock and it resides in the center of the timeline.
Appears whenever users wake Glass up
Provides voice and touch commands to start other Glasswares

12. Past, Present and Future
• Scrolling To the right of the Glass clock brings the history section.
• Cards naturally decay in the past section.
• Past displays static cards ranging from text, HTML, photos, and videos.
• Scrolling To the left of the Glass clock brings the present and future section.
• Future and Present contain both static and live cards.

At the farthest left of the timeline is the Settings bundle, where you configure Glass settings
