    Extension of the Wahl-Rothermel temporal model for the multimedia documents
    (2007-04-12) Maredj, Azze-Eddine; Alimazighi, Zaia; Sadallah, Madjid
    Multimedia presentation defines composition of different media having inherent or assigned temporal behavior: text, images, animations, audio and video. Temporal composition is the most important feature of multimedia presentations because it defines the overall scheduling of temporal events. In this paper, our goal is to propose an extension of Whal and Rothermel temporal model to increase its degree of expressiveness. For that, a new delay definition is proposed.

    Un modèle logique de documents pour les interactions multimédia
    (JTEA, 2008-05-02) Maredj, Azze-Eddine; Alimazighi, Zaia; Tonkin, Nourredine; Sadallah, Madjid
    La dimension temporelle d’un document multimédia interactif confère à ses objets des comportements différents de ceux d’un document classique. De nouveaux besoins de lecture doivent être considérés pour maîtriser sa complexité de perception. Les interactions utilisateur sont une solution à ces besoins. Toutefois, dans les systèmes multimédia actuels, c’est uniquement sur les objets du document que reposent ces interactions et de plus le lecteur est réduit à un rôle passif. Dans cet article, nous proposons un modèle logique de documents multimédia où les objets ne sont plus perçus comme des entités indissociables mais peuvent être regroupés en scènes définissant des parcours de lecture selon le besoin. De plus, le lecteur peut définir ses propres parcours de lecture. Un ensemble de mécanismes d’interactions y est proposé. --------------- The temporal dimension of an interactive multimedia document confers to its objects behaviors different from those of a traditional document. New needs for reading must be considered to control its complexity of perception. The user interactions are a solution to these needs. However, in the current multimedia systems, the interactions are based only on the document objects and the reader is reduced to a passive role. In this paper, we propose a logical model for multimedia documents where the objects are no longer seen as inseparable entities but can be grouped into scenes defining paths of reading as needed. In addition, the reader can define its own paths of reading. A set of interaction mechanisms is proposed.

    MediaStudio : Un système d’édition et de présentation de documents multimédia interactifs
    (CERIST, 2010) Maredj, Azze-Eddine; Sadallah, Madjid; Tonkin, Nourredine
    In the actual standards and multimedia systems, the documents are often written in an event based approach which makes the programming techniques not adapted to the incremental edition process. The documents maintenance has become very hard and very expensive and the construction of such documents is not adapted to the non-computer scientist users. Moreover, works done in this field have mainly focused on the temporal dimension while the development of such systems should consider all the multimedia document dimensions (temporal, spatial, structural and hypermedia) to mutualize their conception and implementation. Furthermore, the documents adaptation to particular users reading profiles is not considered whereas for some application fields, like learning, this remains an important need. On the basis of those observations, MediaStudio will try to be a contribution to the field of editing and presenting interactive multimedia documents through a set of propositions to compensate the mentioned insufficiencies.
