Abstract : Invented at the end of the nineteenth century, the noun "ambiance" describes the shareable perception that we can have of a place, a moment or a relationship with others. It is in fact a "key word" that is used as much to open a phenomenological approach to the ecosystem, natural or built in which the human intervenes, as to describe more specifically a salient phenomenon. It is also and above all a "tool word", necessary for the understanding and the conception of the places in that it induces to take charge, in the analysis and in the conception, the physical and symbolic interactions of atmospheric phenomena, Sound, of uses in the built space. Whether for analysis or for design, it is necessary to go through a stage of representation and thus for the ambiences, of figuration of the intangible. A preliminary step is to identify a graphic corpus of climatic and sound phenomena and it will be verified that it already allows to accompany the project precise indications as to the intentions of control and regulation of the environment. However, it is not sufficient to relate three perceptual thicknesses that could be called "background", "intelligible" and "salient"; The sensitive qualification of an environment being the appreciation that one can have of one or the other of these thicknesses. The stage of representation reveals the cognitive aspects that accompany the perception of a place by attaching it to a context, in the form of a narrative, a temporal dynamics, an identification of sensitive figures, symbolic values And attention. With the narrative, an atmosphere becomes an updated space and consequently a denoted space. The latter is characterized by a certain number of indices which connect it to a distant other, fictional or not, with which it establishes relations of imitation or resemblance. Three families of space facilitating denotation are characteristic: the topical, the archetypical and the synecdoche of atmosphere. The validation of these hypotheses inevitably involves the project and the implementation of variable configurations making it possible to discern the influence and the variability of each factor while preserving a phenomenological approach. For obvious practical questions, it is therefore appealed to the virtual and the immersion of the subject in a fiction to begin to understand the functioning of the phenomena and to test their intensity on a spectator. It is therefore necessary to grasp a new problem to simply specify the protocol of experimentation. If one now knows that a virtual experience is neuronal in a way very close to a real experience, it is nevertheless necessary that a thorough reflection must be conducted on what the " We call it "immersion" and on the nature of the devices mobilized, says otherwise, it is a question of working simultaneously on the medium and on the content. The devices arrive at the illusion of immersion by performing three movements: the first is the envelopment of the spectator by overflowing its visual space, the second is the detachment of the real world by sidereation by saturating it with new sensory information, the Third is engagement in the virtual world, by means of real or non-real interaction interfaces. The conjunction of the three gives the illusion of entering a diegetic space, passing on the other side of the screen developing the idea of ​​transgression. The digital tools used in immersive devices greatly assist in teaching and designing atmospheres. The projects do not necessarily concern achievements for the contemporary world, they can be very favorably mobilized, alongside the archaeologists, for restitutions of historical contexts and atmospheres.
