Abstract

The ACAV project aims to improve videos accessibility on the Web for people with sensory disabilities. For this purpose, additional descriptions of key visual/audio information of the video, that cannot be perceived, are presented using accessible output modalities. However, personalization mechanisms are necessary to adapt these descriptions and their presentations according to user interests and cognitive/physical capabilities. In this article, we introduce the concepts needed for personalization and an adaptive personalization mechanism of descriptions and associated presentations is proposed and evaluated.
