A virtual reality installation

This article presents a virtual reality installation similar to a CAVE based system but less expensive and easily transportable. Like any virtual reality system else, our installation aims to immerse a user in a virtual environment. Hence, we especially focus on the userpsilas feeling of presence which means the user should be able to feel the presence of the virtual objects and his self-presence in the virtual environment. Thus, the installation must conform to the next four conditions: an immersive environment, interactions, to keep the coherence between the perception of the virtual world and the interactions and to propose an experience which generates emotions.
