10. AR categories Video see through Video stream of environment Augmentations on on top of video stream E.g. Smartphones, Webcam AR Optical see through Augmentation projected on Optical device Augments actual real world elements, not video stream

11. Recap: History of AR Glasses not new First research projects focused on Optical see-through HMDs HMD, Backpacked computer, GPS, compass E.g. Feiner et.al. (1997), Thomas et.al. (1998) Development of mobile phones focus shifted to mobile devices Mhrig et. al (2004) first 3d Marker Tracker Wagner, Reithmayr (2008) first NFT Tracker on mobile phone 2012: Announcement of Google Glass Explorer Edition avaialable from 2013 Started a Hype Many Vendors surfaced

12. The other third screen? Desktop Mobile Augmented Reality Information Density Context Relevance + =

13. Eyewear

14. Google Glass 360 16:9 640 Field of Vision Heads-Up Display No see-through Companion App No GPS in-built Voice Commands Basic controls on device Runs Android 4.4

15. Google Glass - Findings No real Augmented Reality Only annotations Needs own SDK (GDK) for Development UI Specifically designed for interaction paradigms Gets hot very easily Esp. longer usage of camera

16. Vuzix M100 Field of Vision 16:9 360 640 Heads-Up Display No see-through Companion App Basic Controls on device Runs Android 4.0

17. Vuzix M100 - Findings No Real Augmented Reality Small screen allows very little information Supports Android SDK Different headsets for different use cases Very small display Very hard to navigate through menu

18. Epson Moverio BT-200 540 16:9 960 Binocular see through External controller unit 3D Stereoscopic view Runs Android 4.0 GPS built-in

19. Epson Moverio - Findings Allows actual Augmented Reality Applications Needs Calibration Android SDK Enable/disable 3D Stereoscopic mode Projects simple Android screen Main interaction with controller unit No hands free interaction

20. Optinvent ORA Moncular see-through Camera: 5MP Sensors: GPS Orientation Trackpad for Interaction Android 4.2.2 480 4:3 640 Field of Vision

21. Optinvent ORA - Findings Still in development No Consumer Version available Android SDK Allows real AR Also needs calibration Interaction similar to Google Glass

22. Calibration Difference of user view and camera view Camera not aligned Account for displacement of integrated camera Account for angle between camera user view Account for field of view of user

23. Calibration

24. Interaction with eyewear Voice Commands Controller Unit Companion App Gesture Control

25. Interaction Very diverse concepts Not as simple as interaction with phones Search for optimized interaction Aim for hands free interaction User can use hands for other tasks Guide user (e.g. Maintenance)

26. User Interface we wish for Source: Cybershack, ExploreEngage.com

27. User Interface we get

28. How to define Interfaces ?

29. User interfaces for eyewear Very small screen What information is relevant for the user? Context awareness Application often not the lone focus of user Guidance, Assistance applications Needed fast information processing

30. Challenges Small screen estate Always in front of user Information density How often can you show information Limited cursor or not clickable at all Minimal battery capacity Low CPU power

31. Challenges - AR Similar problems to AR on early mobile phones Restricted computation power Restricted memory Small screens How to create real optical see-through experience ? account for displacement of camera Account for size of display Needs calibration for correct augmentation

32. Summary Very different designs Some still under development Mostly Android based Varying interaction concepts Basic to allow interaction with glasses Specifically designed for Glasses

33. Summary contd Use case based interaction design Use case based UI design Most interaction paradigms dont work on Glasses Touch based navigation best solution? How much information needed for user?
