An Experimental Comparison of Three Optical Trackers for Model Based Pose Determination in Virtual Reality

Abstract

In recent years many optical trackers have been proposed for usage in Virtual Environments. In this paper, we compare three model based optical tracking algorithms for pose determination of input devices. In particular, we study the behavior of these algorithms when applied to two-handed manipulation tasks. We experimentally show how critical parameters influence the relative accuracy, latency and robustness of each algorithm. Although the study has been performed in a specific near-field virtual environment, the results can be applied to other virtual environments such as workbenches and CAVEs.
