Résumé: This article presents a meta-model of user interfaces, based on the idea of mental models. This meta-model provides its utility in single-user environments as well as those for multiusers. A prototype is presented that implements the meta-model and two trial areas are chosen for discussing its operation. The most innovative aspect is unifying di!erent use schemes in one interface, like temporary, spatial, networked or structured data organizations.
