Abstract
Scenography is a labour comprised of interrelationships between art and expert. It is based on space projection and news temporalities effort (production) and participate to a declaratory context (reception). Our ethnolinguistic approach describe and analyze practicals problems exposed by scenographers during professional moments and how they resolve them interactionally. In this article, we develop scenographic production and describe a particular activity : exposition space projection. For that, we explain a part of our scientific corpus (extract from Scenoscope project) that rest on Jewels exposition implementing in the city of Agde. We have collected observations and survey datas during several working sessions where principals actors of this cultural project were. Through this research field, we must define projection activity as a typical part of scenographic work.
