Laboratory of Simulation and Evaluation of the Environment (LSEE)
The Laboratoire de Simulation et d'Évaluation de l'Environnement (LSEE) is a remarkable piece of equipment managed and developed by the MODIS laboratory. It enables individuals to be immersed in an environment reproduced using synthetic or recorded images and sounds. This makes it possible to study how people's perceptions, decisions and behaviors are influenced by contextual factors. The latter can be directly linked to the environment (sound, visual) or to communication modes and content, social interactions, objects and situations proposed to raise awareness or act on these decisions, behaviors or perceptions. Experiments are thus carried out, immersing participants in a given context. They are based on simulations designed to reproduce a sound and visual environment as close as possible to reality.
This equipment is equipped with a digital audio station, whose 20 analog outputs enable the implementation of advanced multi-channel audio reproduction systems (wavefront synthesis, ambisonic, binaural, etc.). It also features a graphics station with 8 display outputs and excellent 3D rendering capacity. This enables the use of one or more screens, as well as virtual reality headsets.

The platform in detail
The LSEE has the capacity to offer a variety of alternatives for simulating real or imaginary, explorable and interactive scenes. Three main types of applications can be distinguished:
- simulation of the context of an inhabitant;
- immersion in an explorable and interactive virtual environment;
- interactive audio-visual applications.
For example, in recent years, research has focused on the perception of the noise of two-wheelers and thus to observe whether the modifications obtained in terms of acoustics were well perceived by participants placed in the situation of residents, the noise of the tramway and its insertion into urban traffic, the interactions between the visual and the sound in particular during the implementation of noise barriers, the perception of aircraft noise and the comparison of scenarios of evolution of aircraft noise (current/future) and to predict what would be the reactions of the residents subjected to these modified noises. It has enabled significant results to be obtained: the validation of the use of virtual reality to develop and deepen research in the field of environmental perception and evaluation, and the justification for the use of this methodology in predicting reactions to new developments or new environmental situations. Within the framework of the PUNCH project, it has enabled the study of the psycho-social conditions of the commitment to change in the behaviour of individuals in terms of choice of transport modes, and the forms of communication likely to facilitate it.
