Simulation of a virtual reality tracking system

Kapil Patel, Wolfgang Stuerzlinger
2011 2011 IEEE International Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems Proceedings  
In this paper, we simulate a laser-based tracking system that was originally developed for a six-sided spatially immersive system in environments with one and five walls to evaluate its performance for  ...  Note that the "ceiling only" case is also equivalent to a user pointing a hand-held device at a large screen, so we expect our results to generalize to the scenario of pointing a tracking device at a large  ...  This enables auto-calibration of cameras. Due to the recursive nature of this algorithm it is not suitable for initialization of the tracker.  ...
