Under the academic responsibility of Prof. Didier Grandjean and the technical responsibility of software engineer Emmanuel Badier, the BBL is equipped with a high-end Virtual Reality CAVE system. This system allows researchers to benefit of the state of the art in virtual reality for creating and using immersive virtual environments. The manipulations of visual, auditory, and olfactory sensations coupled with the possibilities to track eyes, head, and body movements of one participant allow scientists to investigate complex behaviors in realistic scenes. Moreover, physiological measures (e.g. heart rate, skin conductance, muscular activity) as well as EEG measures can be done into the system. This tool allows researchers to immerse some participants in a virtual world presenting various situations and stimuli, entirely controlled by researchers.
