- 11. 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
- 12. 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 – Möhrig 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

- 14. Eyewear
- 15. 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
- 16. 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
- 17. 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
- 18. 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
- 19. Epson Moverio BT-200 540 16:9 960 • Binocular see through • External controller unit • 3D Stereoscopic view • Runs Android 4.0 • GPS built-in
- 20. 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
- 21. Optinvent ORA • Moncular see-through • Camera: 5MP • Sensors: – GPS – Orientation • Trackpad for Interaction • Android 4.2.2 480 4:3 640 Field of Vision
- 22. Optinvent ORA - Findings • Still in development – No Consumer Version available • Android SDK • Allows real AR – Also needs calibration • Interaction similar to Google Glass
- 23. 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
- 24. Calibration
- 25. Interaction with eyewear Voice Commands Controller Unit Companion App Gesture Control
- 26. 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)
- 27. User Interface we wish for Source: Cybershack, ExploreEngage.com
- 28. User Interface we get
- 29. How to define Interfaces ?
- 30. 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
- 31. 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
- 32. 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
- 33. Summary • Very different designs • Some still under development • Mostly Android based • Varying interaction concepts – Basic to allow interaction with glasses – Specifically designed for Glasses
- 34. Summary – cont’d • Use case based interaction design • Use case based UI design • Most interaction paradigms don’t work on Glasses – Touch based navigation best solution? – How much information needed for user?
