An immersive virtual reality room has been set up at Université Gustave Eiffel-ESIEE Paris. The spectator/actor is immersed in a virtual scene projected in 3D using polarized video projectors. Equipped with 3D sensors and data gloves, they can interact with the calculated scene in real time. The room is also equipped with individual immersive headsets. The room was designed to meet research and teaching needs. Its aim is to enable Virtual Reality experiments to create environments leading to 3D representations, particularly with regard to visual and sound aspects.
