RESUMELe couplage de ressources d'interaction est l'un des fondements de l'informatique ambiante où l'utilisateur construit son espace par assemblage d'entités. Dans cet article, nous explorons de manière rationnelle cette notion étudiée jusqu'ici de manière exploratoire. Nous proposons comme point de départ un cycle de vie du couplage dont les états devraient êtres observables et contrôlables de manière souple et robuste par l'utilisateur. Nous illustrons notre propos avec l'état de l'art et les couplages mis en oeuvre dans I-AM, un intergiciel permettant la construction dynamique d'un espace d'interaction multi-écran, multi-pointeur, multi-clavier. MOTS CLES : Couplage de ressources d'interaction, technique d'interaction, informatique ambiante ABSTRACTAlthough coupling interaction resources is key to ubiquitous computing, this notion has been overlooked in previous studies. In this paper, we address this notion in a more systematic way by describing coupling as a finite state machine whose states should be maintained observable and controllable by users in a flexible and reliable manner. We illustrate the discussion with state of the art demonstrators as well as with I-AM, a middleware that supports the dynamic construction of multi-screen, multi-keyboard, and multi-pointer interactive spaces.
Abstract.Coupling is the action of binding two entities so that they can operate together to provide new functions. In this article, we propose a formal definition for coupling and present a graph theoretic notation so that the side-effects of the creation of a coupling can be analyzed in a formal and systematic way. We then describe I-AM (Interaction Abstract Machine), a middleware that supports the dynamic coupling of interaction resources such as screens, keyboards and mice, to form a unified interactive space. Using our notation, we illustrate how couplings are supported in I-AM.
