This research is part of Project CLES (Cognitive Linguistic Elements Stimulation) whose objective is to develop a serious game, available online, for the evaluation and rehabilitation of cognitive disorders. This project aims, on the one hand, to create for each cognitive disorder a mini-game that is targeted to a very specific aspect of the disorder, while optimizing, through techniques of video games, their cognitive ergonomics. On the other hand, it aims to develop a module to generate, for each patient, personalized paths through the game keeping into account the patient’s difficulties and progress. Cognitive disorders that we consider in this project are: perception, attention, memory, oral language, written language, logical reasoning, visuo-spatial and transversal skills. In this article, we are particularly interested in the generation of courses. This means to propose an intelligent system for the generation of learning scenarios taking into account the user's profile, therapeutic objectives and interaction traces. We define a scenario as a series of educational activities in the form of games, allowing the user to achieve one or more therapeutic goals. This article is organized as follows: after positioning our work and giving a brief description of the project CLES, which is the application context our work, we present the general architecture of our system. This includes the knowledge models and the working of the scenario generator. Afterwards, we present the evaluation protocol, which we have proposed to conduct our evaluations. We also present the results of experimentation that have been conducted with an expert speech therapist.
