The Glass Class - Tutorial1 - Introduction to Glassware Development
2 likes2,839 views
The document provides an introduction to developing glassware applications using the Mirror API and Glass Development Kit (GDK). It explains that the Mirror API is used to create static timeline cards through a web-based application, while the GDK allows developing live cards and immersive Android apps that run directly on Glass. Examples of each are presented to illustrate the differences between the two approaches and how they integrate into the Glass user interface.
The Glass Class - Tutorial1 - Introduction to Glassware Development
- 1. The Glass Class: Introduction to Glassware Development with Mirror API & GDK July 7th – 11th 2014 Mark Billinghurst, Gun Lee HIT Lab NZ University of Canterbury
- 2. An Introduction to Glassware Development with Mirror API & GDK Gun Lee * Images in the slides are from variety of sources, including http://developer.android.com and http://developers.google.com/glass
- 5. A Card in the Timeline
- 7. Glassware and Timeline Static Cards Static content with text, HTML, images, and (link to) video. e.g. notification messages, news clip Live Cards Dynamic content updated frequently. e.g. compass, timer Immersions Takes over the whole control, out from timeline. e.g. interactive game
- 8. Glassware Development Mirror API Server programming, online/web application Static cards / timeline management GDK Android programming, Java (+ C/C++) Live cards & Immersions https://developers.google.com/glass/
- 9. Mirror API REST API Java servlet, PHP, Go, Python, Ruby, .NET Timeline based apps Static cards - Text, HTML, media attachment (image & video) - Standard and custom menu items Manage timeline - Subscribe to timeline notifications - Sharing with contacts - Location based services
- 10. Mirror API based Web App 3. Insert a static card User sees the card Glassware Web app https://developers.google.com/glass/develop/mirror/stories
- 13. Develop with Mirror API Create a project on Google APIs Console Prepare a web server https callback for OAuth 2.0 Minimum storage for credentials Create a web application Java servlet, PHP, Go, Python, Ruby, .NET Implement Oauth 2.0 authentication Use Mirror API to make REST API calls - Wrapper classes/methods provided
- 14. Mirror API in Raw HTTP
- 15. Mirror API Java Python PHP
- 16. Example
- 21. GDK Glass Development Kit Android 4.4.2 + Glass specific APIs Use standard Android Development Tools
- 22. GDK GDK add-on features Timeline and cards Menu and UI Touch pad and gesture Media (sound, camera and voice input)
- 23. Live Cards vs. Immersions Live cards display frequently updated information to the left of the Glass clock. Integrate rich content into the timeline Simple text/images to full-blown 3D graphics Immersions let you build a user experience outside of the timeline. Build interactive experiences Extra control, less user input constraints
- 24. Live Cards
- 25. Immersions
- 26. Live Cards vs. Immersions
- 27. Develop with GDK Android 4.4.2 (API 19) GDK Preview from the Android SDK Manager. Project settings: Minimum and Target SDK Versions: 19 Compile with: GDK Preview Theme: None (allows the Glass theme to be applied.) GDK samples File > New Project > Android Sample Project On Glass, turn on USB debugging Settings > Device Info > Turn on debug
- 28. Example Launch with voice trigger Android App with a full-screen Activity No theme (Glass system theme applied.) Handle touch input
- 29. Example
- 30. Example
- 31. Summary Use Mirror API if you need ... Use GDK if you need ... Or use both
