The SAGRES system is an educational environment built on the World Wide Web that facilitates the presentation of the information bases of a museum in a way that is adapted to the individual characteristics of each visitor. The interaction with the system may occur individually or in groups of students. The system also offers resources to support some forms of cooperative learning, allowing visitors to interact both synchronously and asynchronously, as well as locally (inside the museum) and non-locally (in places geographically distant from the museum). This cooperative learning is stimulated and monitored by software agents that use the human-computer interaction paradigm called directed improvisation to interact with the user. While helping the user, the agents improvise behaviors similar to human behaviors (e.g., happiness, satisfaction, and vibration), making the interaction friendlier. (Contains 10 references.)
