摘要：This text works around a central question on thinking uses and user in Design; conceived as an abstract and at the same time a creative process: what does the Design make of the user's notion? In other words; how does it use it? How does it integrate it into the heart of its professional practices? This analysis naturally crosses two disciplinary approaches; that of the Design; and that of the information and communication Sciences which worked to define the use in connection with a technical object; the idea will thus be to show the sliding of the appropriation and the uses from the later to the former.
