Mesurer les activités numérisées par leur qualité perçue

How are we to analyze the activities that go on in digital environments whose components are distributed over space and time? We discuss these questions in the context of the theory of subject-oriented activity, which enables us to define the distinctive properties, content and structure of the activity. We have used the theory of mental images as another theoretical base. The `perceived quality' approach is a synthesis of the methodological contributions of these two theories. Starting from this point, we developed techniques for defining the subjective relevance of different elements mediating the activity located in the objects or in the environment. Their perceived quality includes both the observable properties of a situation and the characteristics of the subject (individual or group). The analysis aims to highlight either the perceived quality of the actual characteristics of the situation (here and now) or the history of its constitution (the former experience of the individual or the group) or the expectations of the individual (the content of his goals which anticipates a future situation). We discuss the positive contributions and the limitations of this approach, and illustrate them with case studies.
