Abstract. This paper defines the problem space of distributed, migratable and plastic user interfaces, and presents CAMELEON-RT 1 , a technical answer to the problem. CAMELEON-RT 1 is an architecture reference model that can be used for comparing and reasoning about existing tools as well as for developing future run time infrastructures for distributed, migratable, and plastic user interfaces. We have developed an early implementation of a run time infrastructure based on the precepts of CAMELEON-RT 1 .
This paper addresses the problem of coupling interaction resources. Coupling is the action of binding two entities so that they can operate together to provide a new set of functions. For example, coupling a piece of cardboard with a steerable camera-projector pair results in a portable interactive surface. Although coupling is not a new phenomenon, recent research demonstrates that coupling opens the way to unbounded forms of interaction. Because the risk of introducing complexity is high, we propose an analytical model that can serve two purposes: the model can be used to inform the design of novel user interfaces; the computational version of the model can be used at run time as a mechanism to evaluate candidate solutions when dynamic adaptation to the context of use must be undertaken. We illustrate the contribution of the model with three chosen running examples.
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.
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 two complementary conceptual tools to reason about coupling interaction resources. The first tool is a graph theoretic and algebraic notation that can be used to identify the consequents of causal couplings so that the side-effects of the creation of a coupling can be analyzed in a formal and systematic way. The second tool formulates the problem of coupling using an 8 state automaton that models the life cycle of a coupling and provides designers with a structure to verify that usability properties have been satisfied for each state. We conclude with the concept of meta-UI, an overarching interactive system that shows that coupling is only one aspect of a larger problem space.
