In recent years AR research has focused on various sub areas of interest. Highly developed techniques in Graphics and Virtual Reality allow for increasingly realistic AR visuals. Elaborate tracking systems, input devices and computer vision techniques improve the registration of images and user interaction in AR setups. However, most commonly used AR systems still require sophisticated hardware tracking solutions, or at least fiducial markers [9]. ARToolKit [4] is a software library for building marker based Augmented Reality (AR) applications. Squared black and white markers with an embedded code is used in ARToolKit.
