    Virtual collaborative systems are vital tools for accessing and sharing scientific data visualizations. This paper shows how two different modes of collaboration can affect user performance in a specific exploration task. Experiments with groups of users that are working in pairs showed that the lack of mobility can affect the ability to achieve specific exploration goals in a virtual environment. Our analysis reveals that the task was completed more efficiently when users were allowed to move freely and independently instead of working with limited mobility. In these systems, users adapted their own abilities and minimized theeffect of mobility restrictions. ©2009 IEEE.
