While we have provided developer docs there's nothing like having good working examples to use as a guide when learning a new technology. In the process of developing ezAR we have developed several apps to help drive the process. We will be making these projects available over the next few weeks. The first of which is ezAR Compass.
Some planned enhancements include incorporating points of interest and directional info. I'm partial to Chipotle tacos. So I might customize it as a Chipotle locator with a heads-up display of their menu. Or maybe an iBeacon locator, e.g., estimote beacons.
The ezAR Compass source code is available in github under our MIT-ish license. You can find it here: https://github.com/ezartech/ezar-compass
