Building semi-immersing human-computer interaction environment of virtual teleconferencing based on multi-screen general projection

Building a human-computer interaction environment which supports natural communication and interaction among participant group is the key issue of virtual teleconferencing system, which needs to reestablish the correct space relationship of participants and synthesizing real size video into the virtual environment. We introduce a method that uses multiple projection screens driven by network-connected PCs to construct the spatial and realism semi-immerse virtual teleconferencing environment based on general projection transformation. The experiment shows that participants can interact and collaborate with natural interaction model in there.
