Runtime personalization of multi-device user interfaces: Enhanced accessibility for media consumption in heterogeneous environments by user interface adaptation

Abstract

The diversity of end-user devices in combination with a growing user base poses important challenges for providing easy access to the huge amount of content and services currently available. Each device has its typical set of capabilities and characteristics that must be taken into account to create an appropriate user interface that provides interactive access to multimedia data and services. Furthermore, end-users also have their specific requirements that influence the accessibility of data and services for individual access. The approach we present in this paper is geared towards the idea of universal access to interactive multimedia data and services for everyone, independent of the user characteristics or end-user device capabilities. For this purpose we combine user and device models with high-level user interface description languages in order to decouple the interface presentation from its platform, and to generate the most suitable interface on a per-user, per-device basis making use of the semantics that are provided by user and device profile.
