ARToolKit is a computer tracking library that allows for the creation of strong augmented reality applications that overlay virtual imagery on the real world. To do this, it uses video tracking capabilities in order to calculate the real camera position and orientation relative to square physical markers in real time. Once the real camera position is known a virtual camera can be positioned at the same point and 3D computer graphics models drawn exactly overlaid on the real marker. So ARToolKit solves two of the key problems in Augmented Reality; viewpoint tracking and virtual object interaction.

ARToolKit was originally developed by Hirokazu Kato of Nara Institute of Science and Technology in 1999 and was released by the University of Washington HIT Lab. Currently it is maintained as an opensource project hosted on SourceForge with commercial licenses available from ARToolWorks. ARToolKit is a very widely used AR tracking library with over 160,000 downloads since 2004.
