Nous présentons la construction d'un parcours pour l'apprenant et un environnement auteur intégré dans une architecture orientée services. Nous apportons une solution basée sur les services Web pour l'intégration des données pédagogiques et des applications qui les animent. Nous discutons de la structuration des données et des moyens d'évaluation des connaissances dans le cadre d'un système de gestion de contenu pédagogique. Nous présentons ensuite nos travaux de recherche en cours et une partie des résultats du projet XESOP. Nous présentons enfin notre concept pour la réalisation et l'implémentation de l'éditeur de questionnaires basé sur les technologies des services Web.

Applications hybrides et adaptatives basées Apache Cordova

Les cahiers pédagogiques R&T, Actes du 4ème Workshop Pédagogique des IUT Réseaux et Télécoms (WPRT 2018), Nov 5, 2018

La technique Cordova, supporté par le groupe Apache, est une alternative de développement multiplateforme mobile se basant sur HTML5, CSS3 et JavaScript. C’est une forme de conteneur pour interfacer l'application Web avec des fonctionnalités mobiles natives de l’appareil. Cordova autorise ainsi la conception d'applications mobiles hybrides pour accéder à l'appareil photo, à la géolocalisation, au système de fichiers et à d'autres fonctions mobiles natives. Pour les étudiants R&T cette plateforme met en valeur les connaissances acquises dans les modules de développement Web, la programmation objet et la programmation pour appareils mobiles.

Cloud-based Mash-up Authoring Tools for e-Learning

We argue that this objective can be extended when the learning content is created on a multimodal SaaS authoring and publishing platform with an XML-based language for content and metadata description to satisfy instructional designers for a responsive interactivity coupled with rich and informative substance. This position paper presents a Cloud-services based solution for building a virtual and personal learning environment that combines a wide range of technology and tools for learning-content mash-up authoring and diffusion. The proposed service-based framework is intended to support lifelong learning content creation and to enable mash-up of various learning services and applications by adapting learning objects on desktop and small handheld devices.

Cloud computing is a technology and a business model that allows access to an extensible set of storage and computing facilities with a provision and pay as you go model. This position paper discusses the problem of content adaptation for mobile devices in a cloud context. A device independent model is presented in order to achieve automatic adaptation of the content based on its semantics and the capabilities of the target device. An m-learning software as a service cloud framework is presented for adapting, displaying and manipulating learning documents on smart devices. Some aspects of services integration in the cloud for m-learning are

The main challenge of mobile networking is the contextaware content adaptation. This paper discusses the problem of content adaptation for mobile devices. The adaptation considers the context of the client and the environment where the client request is received. A device independent model is developed in order to achieve automatic adaptation of the content based on its semantics and the capabilities of the target device. A serviceoriented Framework, as part of an e-Learning SaaS Cloud, is presented for adapting and displaying learning objects on small handheld devices, including a text-to-speech solution for learners in moving. Some aspects of e-Learning services integration of in Cloud computing environment are also discussed.

Cela necessite l'application de mecanismes d'animation et de coordination des modules et des activites pedagogiques. Si un systeme e-Learning est une collection d'activites ou de processus, nous pouvons decouper ses fonctionnalites en un certain nombre de fonctions autonomes qui peuvent alors etre realisees separement sous la forme d’applications autonomes ou de e-services, en utilisant la technologie des services Web. Cet article presente notre approche pour la conception et le developpement d’outils e-Learning , qui a ete experimentee dans le cadre du projet XESOP.

This requires animation methods and coordination for modules and pedagogical activities. An e-Learning system can be seen a collection of activities or process, whose functionalities are autonomous functions that may be designed separately as autonomous applications or e-Services, in using Web. This article presents our approach for designing an e-Learning platform that complies with several standards. The work described in this paper has been conducted in the framework of the XESOP project.

A Hybrid Indoor Localization Framework in an IoT Ecosystem

To overcome this lack, we propose a Hybrid Indoor Positioning and Navigation System (HIPNS), based on Li-Fi (Light-Fidelity) localization and optical camera positioning analyses deployed in an indoor environment. The localization approach is based on the fuse of two positioning strategies where the camera-based part is responsible for localizing individuals and recovering their trajectories in zones with low coverage of Li-Fi LEDs. A third-party element is planned to operate in the event of loss of contact. So, the step detection technique and heading estimation are applied in a smartphone-based indoor localization context between two referenced points. The main contribution of this paper focuses on the use of techniques, algorithms, and methods from different spheres of application that generate heterogeneous data. We apply a data integration approach based on REST ...
