X-CAMPUS : démarche et outils pour une assistance proactive contextuelle

International audienceThe contribution of new technologies in the development of the computing gave a rise to news domains of researches such as the Ambient Intelligent (AmI), where the new technologies are used as tools to assist users in their daily tasks. Our study mainly the proactive assistance and the interaction human-machine; we study the contextual proactive assistance in order to design an adaptive system able to determine the needs of user wishing have a virtual assistant. We are interested in the contextual proactive interaction between a human and a conversational agent, that we have named X-CAMPUS. X-CAMPUS stands for eXtensible Conversational Agent for Mul- tichannel Proactive Ubiquitous Services. It aims to assist user in his daily tasks thanks to its ability to perceive the state of the environment and interact effectively according to the user's needs. We show that according to the context, X-CAMPUS notifies the user via personalized messages (e.g., suggestion of restaurants according to their menus and the users' preferences) and also according to the most appropriate channel (instant messaging, e-mail and SMS).La contribution des nouvelles technologies au développement de l'informatique a donné naissance à de nouveaux domaines de recherches tel que celui de l'Intelligence Ambiante (IAm), où les nouvelles technologies sont utilisées comme des outils pour assister les utilisateurs dans leurs tâches quotidiennes. Notre étude porte principalement sur l'assistance proactive et l'interaction homme-machine ; nous étudions l'assistance proactive contextuelle dont le but est de concevoir un système adaptatif capable de déterminer les besoins de l'utilisateur souhaitant disposer d'un assistant virtuel. Nous nous sommes intéressés à l'interaction proactive contextuelle, dans le cadre d'un dialogue entre un humain et un agent conversationnel en ligne nommé X-CAMPUS. X-CAMPUS est l'acronyme de eXtensible Conversational Agent for Multichannel Proactive Ubiquitous Services. Il a pour vocation d'assister l'utilisateur dans ses tâches quotidiennes grâce à sa capacité de percevoir l'état de l'environnement et d'interagir pertinemment selon les besoins de l'utilisateur. Nous montrons que selon le contexte, l'agent notifie l'utilisateur avec des messages personnalisés (ex : suggestion de restaurants selon leurs menus, en accord avec les préférences de l'utilisateur) via le canal le plus approprié (messagerie instantané, e-mail et SMS)

Approche IDM pour le développement d'applications mobiles multimodales

International audienceL'informatique mobile propose différentes façons pour interagir avec les utilisateurs. La variété des capteurs qui équipent les périphériques mobiles (smartphone, tablette, ...) avec leurs modalités associées représente un écosystème important pour tester et valider les propositions scientifiques concernant la spécification des interactions multimodales. Dans cet article et en s'inspirant des travaux précédents de modélisation et de développement des applications multimodales, nous présentons une approche IDM (Ingénierie Dirigée par les Modèles) pour modéliser et générer des applications mobiles multimodales

Supporting Mobile Connectivity: from Learning Scenarios to Multichannel Devices: Special Issue on "Learning as a Ubiquitous and Continuous Communication Attitude"

Guest Editor: Piet KommersInternational audienceThe introduction of distance learning does not only bring a wider audience, but also much more diversity among the learners: first, because it can be integrated more easily into a Life-long Learning strategy; secondly, because the learners are not restricted to a sing le area and thus learners from different countries and with different cultures follow the curriculum. We have observed this in various DL diplomas in which we participate. In this article, we will shed some light on the difficulties and challenges arising from these multi-cultural settings. Based on our research work, we would like to insist on two particular points which are the necessity to adapt the pedagogical settings (e.g. pedagogical scenarios) according to the learners' behaviour to overcome unforeseen problems due to cultural differences and the importance of considering mobile technologies to overcome limited access to the technology in developing countries and to ensure continuous interaction among learners and with tutors

From Metamodeling to Automatic Generation of Multimodal Interfaces for Ambient Computing

International audiencehis paper presents our approach to design multichannel and multimodal applications as part of ambient intelligence. Computers are increasingly present in our environments, whether at work (computers, photocopiers), at home (video player, hi-fi, microwave), in our cars, etc. They are more adaptable and context-sensitive (e.g., the car radio that lowers the volume when the mobile phone rings). Unfortunately, while they should provide smart services by combining their skills, they are not yet designed to communicate together. Our results, mainly based on the use of a software bus and a workflow, show that different devices (such as Wiimote, multi-touch screen, telephone, etc.) can be coordinated in order to activate real things (such as lamp, fan, robot, webcam, etc.). A smart digital home case study illustrates how using our approach to design with ease some parts of the ambient system and to redesign them during runtime

Evaluation précoce et conception orientée évaluation

International audienceTo evaluate how people use the applications, many techniques can be applied. Rather than to set up a system of trace after the design, we propose here to design the applications by grafting from the very start a system of trace more complete and more easily exploitable at the time of evaluation. This system is disengageable and provides use oriented traces at the level of the functional core and the user interface. This oriented evaluation design is based on tasks and aspect oriented programming.Evaluer la façon dont les personnes utilisent les applications peut être réalisé par de nombreuses techniques de recueil et d’analyse. Plutôt que de mettre en place un système de trace après la conception, nous proposons ici de concevoir les applications en greffant dès le début un tel système. Ce système est débrayable et produit des traces « orientées usage » au niveau du noyau fonctionnel et de l’IHM. Ces traces fournissent des informations plus complètes et plus facilement exploitables lors des phases d’évaluation. Cette conception orientée évaluation repose sur les tâches et la programmation par aspects
