Instrumenter la lecture savante de documents multimédia temporels

The evolution of document digitalization and diffusion technologies confronts the scholar to contents and reading methods which exceed the tradition inherited from the theoretical and technical frame of the letter and the print. Taking into consideration the material and spatial nature of the critical activity, where the manipulation of knowledge goes with the manipulation of the objects they are embodied in, this article proposes a reflection on the necessity to prolong the document engineering action in the field of computer human-interaction. It's indeed by the space – the one of the environment and the one of the writing – that the reader brings the temporality of his documents and interpretative plan under control. Our stake is then to understand the critical activity foundations so as to lay down directions for its computer instrumentation.
