Fusion engines are fundamental components of multimodal inter-active systems, to interpret input streams whose meaning can vary according to the context, task, user and time. Other surveys have considered multimodal interactive systems; we focus more closely on the design, specification, construction and evaluation of fusion engines. We first introduce some(More)
Modern window-based user interfaces are actually a special kind of reactive system, and Petri nets may be fruitfully used to design such user-computer dialogues. This paper describes a software engineering tool aimed at supporting the use of high-level Petri nets for the specification, design and implementation of user interfaces in an event-driven(More)
This paper presents a design framework for safety critical interactive systems, based on a formal description technique called the ICO (Interactive Cooperative Object) formalism. ICO allows for describing, in a formal way, all the components of highly interactive (also called post-WIMP) applications. The framework is supported by a case tool called PetShop(More)
This paper addresses the problem of the articulation between task modelling and system modelling in the design of interactive software. We aim at providing solutions allowing the software designers to use efficiently task models during the design process, and to check that the software being built actually corresponds to the requirements elicited during the(More)
The research work presented here belongs in the domain of formal specification of human-software interaction. More precisely, we are concerned by the applying a formal specification technique in the various stages of the construction of an user-driven application, the kind supported by most of the current UIMS. We use the Interactive Cooperative Objects(More)
This paper presents a set of tools supporting the development of interactive systems using two different notations. One of these notations, called ConcurTaskTrees (CTT), is used for task modelling. The other notation, called Interactive Cooperative Objects (ICO), is used for system modelling. Even though these two kinds of models represent two different(More)
Petri Net Objects (P.N.O.) are a high-level, object-structured dialect of Petri nets, primarily devised for the design of parallel systems. We show how this formalism can be used for the specification and design of event-driven interfaces, through the use of a real-life example. We then discuss the potential for dialogue validation, integration in UIMS and(More)
