Created in 1985, the agency is at present under the direction of Olivier Schwartz, formerly trained at the École d’architecture in Paris, France. Contours conceives information and wayfinding systems at public sites: scenography of exhibition in a unique place, signage systems in buildings, wayfinding and didactic presentations in urban projects within the unity of a territory. The referent in all cases is the individual whom we accompany and inform when moving around: the usage scale that serves as the global measure of expectations from a recipient in his immediate surroundings. It determines the frame as well as extent of the agency’s interventions. The notion of a usage scale consists of all ranges in which information design is defined: context, function, duration, as well as restoring the base of analysis and conception to its essentials ¬— the user. Needs are no longer articulated in terms of objectives neither abstract nor treated in isolation, they constitute a new element that integrates — in a dynamic way — with the preexisting ensemble, the local ecosystem. Each addition, every shift necessitates a modelization of its supposed efficiency, while taking in account all interactions: at each stage of a project, programming is indispensable to its integration within the general system.
