Abstract
In this paper, an optical tracking system is introduced for the use within Virtual and Augmented Reality applications. The system uses retroreflective markers which are attached to a special designed interaction device. The construction of the device allows us to gather six degrees of freedom. In order to achieve high tracking precision we introduce a calibration algorithm which results in sub-pixel accuracy and is therefore well applicable within Augmented Reality scenarios. Further the algorithm for calculating the pose of a rigid body is described. Finally, the optical tracking system is evaluated in regard to its accuracy.
