9. Client: Pickering Historic Village

10. Challenge
•
Plaques and written brochures provide
limited bandwidth and clumsy user
experience for explaining the buildings
and their significance
•
Wealth of rich media not currently being
shared; videos of historic dancing, singing,
acting

11. Solution: Mobile Augmented Reality

13. Layar Setup

14. Layar setup
Step 1: Create a user account at Layar.com
Step 2: Upgrade to a publishing account at
layar.com/publishing

16. http://code.google.com/p/porpoise/
PorPOISe is a server for Layar clients. It converts your data sets of POIs
(Points of Interest) into responses to the Layar client. Things like JSON
formatting and distance calculation are all done for you.
PorPOISe XML files and SQL databases as data stores.
Supported Layar features include:

1D (point), 2D (image) and 3D (model) objects

Custom actions

Custom filters (requires some PHP skills)

User authentication and personal layers (requires some more
PHP and web development skills)

17. Installing Porpoise
Step 1: download Porpoise from
http://code.google.com/p/porpoise/
Step 2: copy to your web server (I named
the porpoise root directory ‘layar’)

18. Setup the admin password
To generate an encrypted password, hit URL:
web/dashboard/crypt.php/admin=mypassword
Yields:
$_access["admin"] = '$1$.hLMpYz9$wsy198o7kZ3rfMdB0VXnA/';
Drop this into web/dashboard/users.inc.php

19. Setup config file
Open config/config.xml:
Setup the user:
<developer-id>espozi</developer-id>
<developer-key>Layar doesn't use a developer key anymore</developer-key>
Create an empty Layer:
DDiMIT XML layer configuration
<layer>
<name>ddimitdemo</name>
<connector>XMLPOIConnector</connector>
<source>ddimitdemo.xml</source>
</layer>

20. Add an empty layer XML
ddimitdemo.xml
<?xml version="1.0" encoding="UTF-8"?>
<layer>
<pois>
</pois>
</layer>

21. Sign on to Dashboard

22. Test the layer

23. Your turn

24. Create dev accounts
•
Create an account on layar.com, then
layar.com/publishing
•
Then I will give
you permission
to the DDiMIT
layer

25. Create POIs
•
Goto http://espozi.com/layar/web/dashboard
•
Sign in as admin (ask me for password)
–
Not sure if multiple users can add POIs
concurrently, but let’s try it
•
Create your POIs by clicking “New POI”

26. Test the Layer
•
Using the web
http://www.layar.com/publishing/testpage/page/ddimitdemo/
•
Using your phone:
–
Download the Layar browser to your
iPhone/Android
–
Login as your user
–
Click “Layers” -> “Test”
