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.
