Here are the first screenshots from my initial experiment translating my Old North Church project into an Augmented Reality iPhone app. What you see below is what that interface looks like on the phone itself. The floating black and white image is the image plane placed in the general area it is to be displayed. As you can see, it is floating in the air and not placed exactly where it was intended.

There are a few factors working against me here:

1. This is in a highly residential and densely populated area with dozens of WiFi ports and cell phone interference. The resulting causes the Layar app to inaccurately pinpoint your location.

2. I have found that using the app on the 3G network causes the app to under perform and makes it very hard to find your location while failing to accurately find your position.

3. The Hoppala interface is counter intuitive when it comes to tweaking the placement of media content. Conversely, it is extremely easy to use in conjunction with Layar to host your content and get access to your Point Of Interest URL.

All in all, it took me two hours from starting blind, to walking outside viewing a very crude but complete image in the desired space.

Using a combination of Layar and Hoppala, I am able to place media content at specific GPS coordinates and have that media visible through the iPhone app.

What you see below you is a screen capture across the street from the Old North Church. The phone is able to guide the interface to the correct coordinates but has a difficult time getting the artwork to display correctly as well.
