2. Overview
Mobile AR
Applications
The Browser approach
Layers by example
The Layar API
What’s next for AR?

3. Types of AR
Marker based AR
Webcam recognizes special symbol
Location based (mobile) AR
Runs on mobile phone
Look! No markers!

4. AR Applications
Dedicated AR apps
Generic AR “browsers”
Aim to be the “web browser” for AR content
Examples: Layar, Wikitude

5. The AR browser approach
Browser: just one app (install once)
Open content model
Basic specification for AR data
Content from independent providers
AR Browser = catalog and AR viewer

6. The Catalog
AR content in “layers”
Each layer is registered...
...and listed in a catalog

7. The AR view
@TweepsAround demo at Sprint Nextel Event

8. AR Layers
Some examples

9. Where is...
ATMs
Hotels
Letter Box
Phone Booth (that
would be ironic!)

10. But there’s so much more!
AR is not primarily about dry facts
It’s all about experience
Think out of the box!

11. Entertainment
Position the image and
take a screenshot

12. Social
Where are my friends
on...
Twitter
Foursquare
Gowalla

13. Data visualization
measurement and display of air quality

14. Commercial campaigns
Concept for Coca Cola
Switch on your Layer
and the happiness
factory comes to life.

Discovery
Relevance, personalization
Privacy

21. Building blocks
Many existing techniques can be used:
Wave / XMPP (real time protocol)
Semantic Web technology (discovery, relevance)
Collaborative spam filtering (will become essential)
Many of this comes together in...
