The Augmented Reality ViewFinder Toolkit allows you to "augment" the experience to your Windows Phone 7.5 application. Easily display geolocalized objects over the camera stream to help your user find their way around!
How does it work ?
You probably have an idea of the objects you want to display over the camera feed, depending on their location. The first step is to implement the IAugmentable interface on them - the properties in this interface will be used in the binding of the OverlayItems, which are the controls used to display these objects on the AugmentedViewFinder control. When OverlayItems are too close to each other, they are grouped together in OverlayGroups to improve readbility.
