The collaborative research initiative (ARC) NIEVE aims at:
- Studying the modulation of emotion in audiovisual VEs, focusing on the case of phobia of dogs in the iCube.
- Studying appropriate representations, view combinations/transitions and auditory feedback for effective navigation in VEs
- Developing novel immersive audiovisual interfaces for navigation in VEs
- Developing an innovative emotion-based methodology for the evaluation of immersive navigation interfaces.

INRIA Sophia-Antipolis Immersive Space
The Immersive Space in Sophia-Antipolis has two display devices, a CadWall for its ease of use and an iCube for its immersion quality. Both devices offer 6:1 sound restitution, stereo images and optical tracking. In NIEVE, we will be using the iCube. iCube This display device offers a 3.2m x 2.4m working area. It is made of 3 vertical screens (left, front, right) and an horizontal one (floor). Thanks to the head tracking, it allows a single user to be completely immersed in a virtual environment. It is a unique setup at INRIA since it is the first immersive “CAVE-like” immersive environment of the Institute; in particular, the floor is retroprojected, which is essential for the sensation of immersion and presence. In addition, we provide full Head-Related Transfer Funtion based 3D audio spatialization, delivered over headphones or speakers using Cross Talk Cancellation (planned for 2010). Technical features Enforcing the user experience quality has been one of our main goals. It results in several features:
- Screens Retro projected screens (including the iCube floor) to avoid shadows. Dark screens to enhance contrast.
- Projectors 12k lumen to guarantee brightness. Xenon bulbs for their spectrum.
- Stereo Active Infitec to minimize ghosting and avoid synchronization issues Two different image and sound generators are available:
- a single PC with multiple graphics card and a multi canal sound card,
- a graphics cluster where a master drives one slave dedicated to each projector and a sound server. Graphics cards are Nvidia Quadro 5800FX. A photograph of the iCube is shown below:
