On Using Multiple Disabilities Profiles to Adapt Multimedia Documents

Abstract

Currently, advanced technological hardware can offer mobile devices which fits in the hand with a capacity to consult documents at anytime and anywhere. Multiple user context constraints as well as mobile device capabilities may involve the adaptation of multimedia content. In this article, the authors propose a new graph-based method for adapting multimedia documents in complex situations. Each contextual situation could correspond to a physical handicap and therefore triggers an adaptation action using ontological reasoning. Consequently, when several contextual situations are identified, this leads to multiple disabilities and may give rise to inconsistency between triggered actions. Their method allows modeling relations between adaptation-actions to select the compatible triggerable ones. In order to evaluate the feasibility and the performance of their proposal, an experimental study has been made on some real scenarios. When tested and compared with some existing approaches, their proposal showed improvements according to various criteria.

On the use of historical data in context-aware multimedia documents adaptation processes

“…Only the spatial dimension of objects is handled but not their temporal synchronization. Saighi et al (2020) [20] Server-side A graph-based MDA that allows the inference of multiple adaptation actions using semantic reasoning upon users context.…”

“…In fact, from a functional point of view, most MDA processes work very well. However, when it comes to validating a given adaptation approach, the prototypes developed are often based on simulation to collect context elements; mainly for the elements related to connected objects (see for example [11], [12], [20]). Indeed, even if the simulation paradigm is very useful in many situations, the realization of a real prototype remains the most ideal, realistic and viable solution, in particular to deal with technical, and implementation issues.…”

“…Table 5 gives details of a subset of typical adaptation actions. To build these rules, we are inspired by those used in [12], [20].…”

“…b. Server-side adaptation: the devices playing the documents send adaptation requests to a server that deals with them (e.g. [20]). Although this option frees the client side from a tedious process that could slow down performance, this may affect the server response time due to overload.…”

A Multi-Viewpoint Approach For Semantic Multimedia Documents Adaptation

“…The authors in [12], the authors propose a new approach for adapting multimedia documents that extends HaMA [2]. their main contribution focus on, solving the problem of inconsistency between deduced actions in order to efficiently select the set of consistent ones, using graphs.…”
