A team from INRIA and Grenoble Universities in France will demo a new virtual reality system called Virtualization Gate that tracks users' movements very accurately using multiple cameras, allowing them to interact with virtual objects with new realism.A user wears a head-mounted display (HMD) and moves through a virtual space while several cameras track his movement. The video here shows a guy kicking over virtual vases and pushing a virtual representation of himself around. A cluster of PCs is needed to perform the necessary image capture and 3D modeling.
