De l'interaction homme-machine individuelle aux systèmes multi-utilisateurs. L'exemple de la communication homme-homme médiatisée

Abstract : This thesis focuses on the design and implementation of multi-user systems. Our conceptual model describes a multi-user system as relying on the combination of three functional spaces: the production space, the coordination space, and the communication space. We concentrate on the latter, which covers communication between users and defines computer-mediated communication. Our approach is made up of three levels: principles are defined by social and psychological sciences, properties are derived from principles and drive the design and evaluation phases, techniques are used to effectively build the system. Principles express contributions from the social and psychological sciences to our field of study. The Garden Movie psychology experiment studies the influence of camera and work area positions for a cooperative task. We use it to illustrate the use of principles. Properties are features of a system that can be verified. The choice of a relevant set of properties is driven by principles. We propose properties for multi-user and computer-mediated communication systems. Properties drive the design and the usability study of a system. We present the NEIMO user behaviour observation and Wizard of Oz platform. We illustrate its use for the study of computer-mediated communication systems with the Supratel system. Techniques may be software architecture models used to drive the implementation or implementation tools. Properties that the system should verify drive the choice of techniques. We present a problem space for software architecture models for multi-user systems and we use it to evaluate models proposed in the litterature. We note that no model actually covers harmoniously the three spaces of our conceptual model and that the models are not satisfying for computer-mediated communication. Thus, we present CoPAC, our software architecture model for multi-user systems and computer-mediated communication. We illustrate the use of CoPAC with the implementation of VideoPort, our mediaspace system. We also describe the UserLink library for continuous media. Finally, we propose the IMPACT classification for computer-mediated communication tools.
