Can web design methodologies (actually) help practitioners?

There exist many web design methodologies and the new ones are constantly being added to the pool of those offered to practitioners. However as previous research shows, practitioners either do not know, do not use or even do not care for these development approaches. This paper examines web design practice, and the design of visual aspects in particular, in order to establish whether any of the existing methodologies would actually address the practitioners concerns. Through grounded theory analysis, it transpires that from amongst several examined approaches, IS-based web design methods are dealing with great many practical issues which designers perceive as most pressing.<br /

Application of Grounded Theory to Exploring Multimedia Design Practices

This paper describes the application of Grounded Theory to an exploration of multimedia\ud design practices. It discusses the opinions of multimedia developers, as elicited from\ud interviews, on the selected design tasks and the processes employed in their completion. Our\ud findings, which emerge from the analysis of the collected data, indicate that the currently\ud available multimedia models do not address some of the important concerns of practitioners.\ud We believe that closing the methodological gaps in these models would provide better\ud support for the multimedia development process

NAC, une architecture pour l'adaptation multimédia sur le web

National audienceThe Web is evolving towards richer contents and diverse media that are accessed with different devices through multiple kinds of network. This heterogeneous, mobile and changing environment requires that multimedia information delivered by servers be adapted to the actual conditions of use. For that purpose, a number of methods, languages, formats and protocols are developed, especially by W3C. The NAC architecture presented in this article was designed and implemented based on these technologies, focusing on adaptation processing, on environment description models, on negotiation protocols, and on content transformations

ZYX - A Semantic Model for Multimedia Documents and Presentations

: Existing languages, formats, and multimedia document models such as HTML, MHEG, SMIL, HyTime, SGML, and XML, do not provide the appropriate modeling primitives needed to provide adequate support for reusability, interaction, adaptation, and presentation-neutral description of the structure and content of multimedia documents as required in the Cardio-OP project. Since each of these models lacks some significant concepts and does not meet all of the requirements, we propose a new approach for the semantic modeling of multimedia content, the Z Y X model, which we implemented on the basis of an object-relational database system. The approach taken allows for fine-grained representation and retrieval of structures and layout of multimedia material, for flexible on-the-fly composition of multimedia fragments in order to create individualized multimedia documents, and for the realization of adaptation and personalization of multimedia presentations depending on the user environment specifi..

MediaSync: Handbook on Multimedia Synchronization

This book provides an approachable overview of the most recent advances in the fascinating field of media synchronization (mediasync), gathering contributions from the most representative and influential experts. Understanding the challenges of this field in the current multi-sensory, multi-device, and multi-protocol world is not an easy task. The book revisits the foundations of mediasync, including theoretical frameworks and models, highlights ongoing research efforts, like hybrid broadband broadcast (HBB) delivery and users' perception modeling (i.e., Quality of Experience or QoE), and paves the way for the future (e.g., towards the deployment of multi-sensory and ultra-realistic experiences). Although many advances around mediasync have been devised and deployed, this area of research is getting renewed attention to overcome remaining challenges in the next-generation (heterogeneous and ubiquitous) media ecosystem. Given the significant advances in this research area, its current relevance and the multiple disciplines it involves, the availability of a reference book on mediasync becomes necessary. This book fills the gap in this context. In particular, it addresses key aspects and reviews the most relevant contributions within the mediasync research space, from different perspectives. Mediasync: Handbook on Multimedia Synchronization is the perfect companion for scholars and practitioners that want to acquire strong knowledge about this research area, and also approach the challenges behind ensuring the best mediated experiences, by providing the adequate synchronization between the media elements that constitute these experiences
