Distributed collaborative environment with real-time tracking of 3D body postures

In this paper a multi-user motion capture system is presented, where users work from separate locations and interact in a common virtual environment. The system functions well on low-end personal computers; it implements a natural human/machine interaction due to the complete absence of markers and weak constraints on users’ clothes and environment lighting. It is suitable for every-day use, where the great precision reached by complex commercial systems is not the principal requisite.
