![]() Ce démonstrateur vise à mesurer l'expressivité des modèles définis en les expérimentant sur la conception d'applications géographiques variées. Pour mesurer l'apport de cette approche mais aussi des modèles et des langages de conception pro-posés, nous avons mis au point un environnement-auteur nommé WINDMash. Ce langage se veut également riche dans la description de l'interactivité. Ce langage visuel se veut simple afin de pouvoir être appréhendé par des experts d'un domaine (enseignement, tourisme, culture.) n'ayant pas forcément des compétences fortes en informatique. Pour faciliter le processus de conception, le travail de spécification est réalisé de manière visuelle y compris la dimension interactive qui demeure la plus complexe à décrire et pour laquelle nous proposons un langage dédié inspiré du diagramme de séquence UML. L'exécution des modèles permet ainsi de proposer une approche de conception basée sur des cycles courts dans lesquels le concepteur affine ses besoins en enchaînant, autant de fois que nécessaire, des phases de spécification, d'exécution et d'évaluation de son application. Ces modèles se veulent riches pour être en mesure de décrire une grande variété d'applications tout en conservant la capacité à traduire leurs instances sous forme de code exécutable. Les modèles de conception proposés permettent de produire ces applications au service de tâches élémentaires nécessaires à la réalisation d'un objectif. We have developed WINDMash, an authoring environment, to assess our approach, as well as the models and the design languages with a diversity of geographic Web applications.Ĭet article présente un cadre de conception d'applications Web géographiques interactives s'appuyant sur des modèles de conception génériques permettant d'élaborer une application selon trois dimensions : les con-tenus géographiques manipulés, la manière de les afficher mais aussi les comportements interactifs associés. We have demonstrated that this language is sufficiently simple to be understood by domain experts (e.g., education, tourism, culture) with no computer science background. In particular, the interactive behaviour is specified with a language inspired from the UML sequence diagram. Modeling is performed using visual languages. This executability supports an agile design process based on short cycles where designers can refine their needs as many times as necessary by specifying, executing and evaluating their application. They are operational as they are translated into executable code. They are expressive enough to describe a wide variety of geographic applications. The three design models allow designers to develop applications for elementary tasks to achieve a specific goal. This framework includes three generic design models that allow designers to build a geographic application according to three dimensions: geographic content, content rendering and display, and interactive behaviour. This paper presents a framework dedicated to the design of geographic web applications. ![]() We present different examples and source codes that pinpoint the added-value of the WIND model and its API. WIND is a declarative model enabling users to design web interactions between textual, map and calendar components. It is object-oriented: users can consistently describe interactions whatever the source and target components are. It is fully executable (thanks to the WIND JavaScript API). The main characteristics of WIND are then presented and discussed: WIND is integrative (it combines textual, map and calendar components it also combines Web Mapping Services, etc.). We present the core concepts of WIND (eventreaction- interaction processing), its API and we illustrate the WIND model with different examples. In this article, we report on Web Interaction Design (WIND), a web interaction lightweight programming model that we designed to help users to describe interactions between textual, map and calendar components. ![]() 156–174) making use of geographical information avoiding any programmer intervention. In: Chapter 8, Web-based intelligent e-learning systems: technologies and applications, pp. Our research problem is enabling teachers to design by themselves an Active Reading Learning Scenario (Murray T (2005) Hyperbook features supporting active reading skills. Different works and experiments have shown that current Web Mapping Services and frameworks are partially unfitted for the design and easy programming of web applications dedicated to the teaching of geographic information. ![]() ![]() Recent research has attested the implementation and the effectiveness of Geographic Information Systems in geographic teaching (Kerski Demirci ). ![]()
