Nguyen, T., Sandor, C., and Park, J. PTAMM-Plus: Refactoring and Extending PTAMM In Proceedings of International Conference on Artificial Reality and Telexistence, pages 96--100, Adelaide, SA, Australia, December, 2010.
Augmented Reality (AR) is a promising candidate for the next gen- eration of human computer interaction. However, a great number of obstacles have to be overcome in order to make AR become widely- acceptable. Among those obstacles, tracking is one of the ma- jor well-known challenges. The state-of-the-art in AR proved that PTAMM is one of the most promising tracking systems. However, it is quite difficult to develop AR applications based on PTAMM system because of its monolithic architecture. Therefore, modu- larizing it for seamless integration is needed. On the other hand, PTAMM distorts graphic results instead of undistorting the video images, the result of which is a distorted augmented view. In this paper, we present PTAMM-Plus, which refactored and extended PTAMM by developing a well-formed API, re-arranging threads, and improving the undistortion mechanism. Using PTAMM-Plus, AR developers may easily build AR applications independently on top of PTAMM. By rearranging threads and undistortion mecha- nism, presented PTAMM-Plus also enhanced performance and ac- curacy. In this paper, a testing oriented approach in software devel- opment was applied when implementing the PTAMM-Plus.
