An Adaptive Human-Computer Design Method Led By Objectives

Work presented here, concerns the design of human-computer interaction within the framework of the industrial systems of supervision. In such a context, the user is often considered as a decisionmaker [1]. He has to identify different solutions, in order to answer a supervision problem, and choose the most appropriate solution within a complex environment. According to the objectives of the task in progress, the choice can be carried out in various manners by taking into account the characteristics of the user such as, his problem solving ability and his experience level [2]...Thus, for this type of context, it appears important to us to integrate, as soon as the designing phase, adaptivity functions and problem solving functions, in order to generate user-centered [3] interfaces of supervision systems. The principle of our designing approach makes it possible to consider any session of use as the realization of one or several high level objectives. The designing approach is based on three phases: a conceptual phase allowing the description of the objectives and the definition of the structure of navigation; a logical phase taking into account the presentation aspects of the interface, and an implementation phase allowing the development of the communication interface. One of the originality of this approach takes place in the concept of the hyperspace [4] used to model the structure and the logical characteristics of a navigation space. In addition, the implementation of the interfacing system is carried out with a multi-agent system making it possible to benefit as much as possible from the distributed aspect of the adaptivity concept.
