Transcript

  • 1. Using Mobile Augmented Reality for Urban Design Mark Billinghurst, Gun Lee HIT Lab NZ University of Canterbury September 2012
  • 2. Christchurch Before and After
  • 3.   3D graphics solutions available   Autodesk REVIST, ESRI ArcGIS, Grass,etc
  • 4. Emerging Novel User Interfaces  Immersive visualization  Multi-touch screens  Gesture interaction  Etc..
  • 5. Limitations  Interface   Complex to use   Unintuitive interaction   2D display for 3D content  Context of Use   Remote visualization   Separation from the real world   Unable to show life-sized content
  • 6. 1983 – Star Wars
  • 7. Augmented Reality  Combines Real and Virtual Images -  Both can be seen at the same time  Interactive in real-time -  The virtual content can be interacted with  Registered in 3D -  Virtual objects appear fixed in space
  • 8. AR for Urban Design
  • 9. MagicCup: Urban Design  Intuitive Virtual Object Manipulation on a Table-Top Workspace   Design your own city   Tangible User Interface -  Intuitive Manipulation
  • 10. Mobile AR for Urban Design  Enhancing plans/documents   Indoor AR use, meeting support   Overlaying virtual content on physical objects -  Visual tracking  Showing content on-site   Outdoor AR use, on-site visualization   Geo-located points of interest (POI) -  Sensor based tracking (GPS, compass)
  • 11. Enhanced City Plans  CERA – CCDU Plan   Using tablet to track off printed maps   Overlay 3D city models onto real maps
  • 12. User Experience  Touch interaction  Pointing selection  Animated objects
  • 13. Outdoor AR (2003)  Backpack system   Laptop, HMD, camera  Highly accurate tracking   GPS, inertial, RTK system   2-3 cm accuracy
  • 14. User Views  Stakeout survey application   Users able to find survey points twice as fast
  • 15. 2008 - Location Aware PhonesMotorola Droid Nokia Navigator
  • 16. Real World Information Overlay  Tag real world locations (POI)   GPS, compass input   Overlay graphics data on live video  Applications   Travel guide, Advertising, etc  Eg: Layar (www.layar.com)   > 20 million users   > 3,000 information channels
  • 17. 3DOn  Onsite Visualization Single Building   GPS + Compass input   Overlay graphics data on live video/Photos
  • 18. HIT Lab NZ Outdoor AR Platform  Cross platform   Android, iPhone  3D onsite visualization   3D model loading   Intuitive user interface  Positions content in space   Camera, GPS, compass  Targeting museum guide/outdoor site applications
  • 19. CityViewAR Application (2011)  Visualize Christchurch before the earthquakes
  • 20. User Experience  Multiple Views   Map View, AR View, List View  Multiple Data Types   2D images, 3D content, text, panoramas
  • 21. Time Usage  Percentage time spent in different views   AR used more then 50% of time when available
  • 22. Navigation Patterns  Red: AR users  Blue: Non-AR users
  • 23. Survey Results  Use of AR improved the user experience   But no difference between AR and non-AR usefulness  Favourite features   AR and Panorama views most popular   Users also enjoyed having rich data available  Main Problems (50% reported no problems)   UI design not intuitive (24%)   System not responsive (16%)
  • 24. AR Urban Design Tool (2012)  CERA CCDU Application   Enhanced CityViewAR application  Add VR view mode   3D model viewing/interaction  Add concept models of buildings   Multiple buildings at single site  Client/Server architecture   Support for user generated feedback
  • 25. VR View
  • 26. Differing Views  List View, Content View, Map View
  • 27. Interaction   Touch interaction   Information filtering   Building information   Model panning, zoom, rotation
  • 28. Looking to the Future
  • 29. Next Steps  Subsurface Visualization   See underground infrastructure  User evaluation   Architects, Urban Designers, Public  Develop authoring tool   Web-based content management system  Improve technology   Tracking, 3D rendering
  • 30. Subsurface Visualization  Using AR to view underground infrastructure
  • 31. Client/Server Architecture Web Interface Add models Web application java and php server Android application Database server Postgres
  • 32. Web based Outdoor AR Server  Web interface   Showing POIs as Icons on Google Map  PHP based REST API   XML based scene data retrieval API   Scene creation and modification API   Android client side REST API interface
  • 33. BASIC VIEW
  • 34. PERSONAL VIEW
  • 35. Augmented Reality 2.0 Infrastructure
  • 36. Leveraging Web 2.0  Content retrieval using HTTP  XML encoded meta information   KML placemarks + extensions  Queries   Based on location (from GPS, image recognition)   Based on situation (barcode markers)  Syndication   Community servers for end-user content   Tagging  AR client subscribes to data feeds
  • 37. iceFest (2012)  Outdoor AR for Antarctic Experience  Visit Antarctica in real world  Using handheld tablet
  • 38. Map Views
  • 39. Content Views
  • 40. AR View  View of ice superimposed over real world
  • 41. Panorama  Immersive 360 panorama
  • 42. Feedback  A = Satisfying, B = Ease to use  C = Useful for learning, D = Better learning than internet
  • 43. Conclusions   AR provides for geo-spatial visualization in place   Text, Images, 3D models  Hardware and software platforms widely available  Many possibilities for urban design applications   Indoor, outdoor AR enhancements  Important research problems need to be solved   Improved tracking, user interface, authoring tools, social interaction, user experience, etc.
  • 44. More Information   Mark Billinghurst   mark.billinghurst@hitlabnz.org  Gun Lee   gun.lee@hitlabnz.org  Websites   www.hitlabnz.org   www.hitlabnz.org/cityviewar   www.hitlabnz.org/mobileAR
  • 45. Try It Yourself  iOS (iPhone/Android)   Search for CCDU on app store  Android – Search on Android Market   CityViewAR – outdoor AR view   CCDU 3D – outdoor AR and 3D view   CCDU AR – AR view
