  2. 2. Augmented Reality (AR) Combining digital data with real-world imagery. GPS location Magnetometer (compass) Accelerometer Camera Much innovation in the mobile AR space has been happening on Android, as the necessary hardware and API has been available since launch.
  3. 3. Wikitude World Browser Presents information about your surroundings (landmarks, points of interest) annotated onto a live camera view Users can contribute their own POIs via wikitude.me First practical AR mobile application available world wide Android Developer Challenge 1 finalist API for Android released September 2009
  4. 4. From existing geo data based application...
  5. 5. ...to AR application
  6. 6. Wikitude API - Getting Started Download API package http://www.wikitude.org/developers Register for an API key (optional during development) Include wikitudearintent.jar within your project build path
  7. 7. Code
  8. 8. Creating the Wikitude AR Intent
  9. 9. Adding Points Of Interest (POIs)
  10. 10. Starting the Intent
  11. 11. Callback Intents
  12. 12. Callback Intents
  13. 13. Callback Intents
  14. 14. Tips Don't add more than 50 POIs to the AR view Test on real devices where possible Emulator requires manual install of the Wikitude APK Location, yaw, pitch and roll instrumentation is painful
  15. 15. Augmented Reality Markup Language (ARML) Proposed open Augmented Reality markup specification based on KML with extensions Adoption will ensure all data that is created for augmentation in the physical world can be universally accessed and viewed on any Augmented Reality browser http://www.openarml.org/
