Immersia Virtual Reality room
Participants : Georges Dumont [contact] , Alain Chauffaut, Ronan Gaugne [contact] , Marwan Badawi.
The team was the first in France to host a large-scale immersive virtual reality equipment known as Immersia (see figure 9 ). This platform, with full visual and sound immersion, is dedicated to real-time, multimodal (vision, sound, haptic, BCI) and immersive interaction. It will accommodate experiments using interactive and collaborative virtual-reality applications that have multiple local or remote users. Our new wall has four faces: a front, two sides and a ground. Dimensions are 9.6 m wide, 2.9 m deep and 3.1 m hight. The visual reproduction system combines ten Barco Galaxy NW12 projectors and three Barco Galaxy 7+ projectors. Visual images from Barco projectors are rendered on glass screens. They are adjusted for the users position, and this, together with their high resolution and homogeneous colouring, make them very realistic. The ART localization system, constituted of 16 ARTtrack 2 cameras, enables real objects to be located within the U-shape. Sound rendering is provided by a Yamaha processor, linked either to Genelec speakers with 10.2 format sound or Beyer Dynamic headsets with 5.1 virtual format sound, controlled by the users position.
The Immersia Virtual Reality room has been inaugurated on 2012, june, the 20th. We have hosted the project VR-GO, a Trans National Acces VISIONAIR project in june 2012. The goal was to evaluate an assembly by comparing different types of interaction : real, virtual and virtual + force feedback [28] .
