let’s make layers!
Creating layers – Terminology Layar: The browser application
Layer: A content layer in our browser
POI: Point of Interest, element of data in the AR view (sometimes called hotspot, or object)
AR View: The augmented reality view, with the POIs superimposed on the camera view.
List View: A list of all POIs
Map View: POIs shown on a map
Layar terminology

Creating layers
Layers are built using simple web technology HTTP, JSON, HTML
2 step process: Create a layer definition in the Layar publishing environment
Create a layer server for delivering the POI content to the phones
Layar ecosystem
Creating layers – Publishing site

Add all the static content of a layer Listing details

Service URL
Creating layers – Layer service
RESTful API with a single HTTP GET call
GetPOIs Request: HTTP request with the following parameters: Latitude, Longitude, filter settings...
GetPOIs Response: JSON data containing POI information (hotspots)
API documentation: http://layar.pbworks.com

Creating layers – 3rd party services
Instead of creating your own layer service, you can use one of the community created tools, e.g.: Porpoise
