ARToolKit is a software library that allows for the creation of augmented reality applications. To do this, it uses video tracking capabilities in order to calculate the real camera position and orientation relative to physical markers in real time. It is being developed at the University of Washington HIT Lab.


* Single camera position/orientation tracking.
* Tracking code that uses simple black squares.
* The ability to use any square marker patterns.
* Easy camera calibration code.
* Fast enough for real time AR applications.
* Free and open source.

Operating systems

It is available for SGI IRIX, Microsoft Windows, Mac OS X and Linux-based systems.
