We propose the CARE properties as a simple way of characterising and assessing aspects of multimodal interaction: the Complementarity, Assignment, Redundancy, and Equivalence that may occur between the interaction techniques available in a multimodal user interface. We provide a formal definition of these properties and use the notion of compatibility to(More)
This article reports our reflection on software architecture modelling for multiuser systems (or groupware). First, we introduce the notion of software architecture and make explicit the design steps that most software designers in HCI tend to blend in a fuzzy way. Building on general concepts and practice from main stream software engineering, we then(More)
Although several real multimodal systems have been built, their development still remains a difficult task. In this paper we address this problem of development of multimodal interfaces by describing a component-based approach, called ICARE, for rapidly developing multimodal interfaces. ICARE stands for Interaction-CARE (Complementarity Assignment(More)
In this paper we present a notation, ASUR++, for describing mobile systems that combine physical and digital entities. The notation ASUR++ builds upon our previous one, called ASUR. The new features of ASUR++ are dedicated to handling the mobility of users and enable a designer to express physical relationships among entities involved in the system. The(More)
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)
Our work focuses on the design of interaction techniques for large information spaces. Our goal is not to define yet another visualization technique but to provide insights for the design of such techniques. Our design approach is based on ergonomic criteria that arose from a study of how the user perceives and manipulates a large information space. We then(More)
Integrating computer-based information into the real world of the user, is becoming a crucial challenge for the designers of interactive systems. The Augmented Reality (AR) paradigm illustrates this trend. Information is provided by the AR system to facilitate or to enrich the natural way the user interacts with the real environment. We focus on the outputs(More)
One of the new design goals in Human Computer Interaction is to extend the sensory-motor capabilities of computer systems to better match the natural communication means of human beings. This article proposes a dimension space that should help reasoning about current and future Multi-Sensori-Motor systems (MSM). To do so, we adopt a system centered(More)
Multimodal interaction enables the user to employ different modalities such as voice, gesture and typing for communicating with a computer. This paper presents an analysis of the integration of multiple communication modalities within an interactive system. To do so, a software engineering perspective is adopted. First, the notion of “multimodal(More)
