Abstract
Augmented Reality (AR) is a promising candidate for the next generation of human computer interaction. However, a great number of obstacles have to be overcome in order to make AR become widelyacceptable. Among those obstacles, tracking is one of the major 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, modularizing 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 mechanism, presented PTAMM-Plus also enhanced performance and accuracy. In this paper, a testing oriented approach in software development was applied when implementing the PTAMM-Plus.
