Tracking in a multi-user augmented reality system
Thomas Auer, Axel J. Pinz · 1998
We present a tracking system integrating both optical and magnetic tracking which runs on low-cost hardware. This tracking system is part of the "Studierstube", a new multi-user augmented reality system. On the one hand, two independently running tracking systems are integrated to complement each other, on the other hand by using only parts of two independent tracking systems we can obtain a unique result which is superior to the complete result of any one of the two systems alone. Keywords: augmented reality, tracking, registration, integration of optical and magnetic tracking 1 Introduction In augmented reality applications, precise registration is important: If the position or orientation of the user cannot be determined precisely, the augmentation will be unsatisfactory: Virtual Objects will be displaced, or even worse, they will freely float around in the space surrounding the user. Thus, precise registration is needed to avoid these symptoms. Further stress on precise registr...
