Augmented reality is somehow a technology that makes scenes generated by computer to merge with scenes captured from the real world. Such as if you capture your own picture or video, which is an object in the real world, and you create a computer-generated background or 3D objects, such as in a deep ocean with fishes swimming around. And using the augmented reality software tool you can merge them, which results a video or a picture that looks so real, that you can hardly differentiate between what is real and what is generated by the computer.

The ARToolKit v4.4 is the first fully-featured AR framework that supports native operation on Apple iPhone, which lets you create applications with sample real world imagery captured with your iPhone camera, and merges them with software-generated 3D objects. The ARToolKit is also well integrated with the accelerometer of the iPhone, which allows it to automatically detect movements from the iPhone, and impose those movements on 3D images instantaneously.

This AR software also allows iPhone to track multiple points simultaneously, and you can easily place new objects in the virtual world using the iPhone’s multi-touch interface.
