Augmented Reality (AR) experiences are becoming increasingly popular within mobile applications. This presentation will demonstrate how developers can add powerful camera-view AR features to their Android applications using the Wikitude API, without having to deal with any of the complexities of device positioning, orientation or camera UI.

1. Augmented Reality using the
Wikitude API
Jeff Gilfelt - November 2009

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. 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. From existing geo data based application...

5. ...to AR application

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. Code

8. Creating the Wikitude AR Intent

9. Adding Points Of Interest (POIs)

10. Starting the Intent

11. Callback Intents

12. Callback Intents

13. Callback Intents

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. 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
