User-centric and personalized access to mobile multimedia systems based on a multimedia middleware

A great research challenge in multimedia systems is the user-centric design and adaptation of interfaces to multimedia systems. User-centric does involve methods of HCI (Human-Centric Interface) research, but should also better incorporate the interest of the users, the usage context and the technical properties of the system. This work focuses on multimedia systems in the domain of emergent interactive TV applications. These systems are very dynamic and rich in their interaction patterns and require hyperlinked, browsing, searching and collaborative access to different multimedia resources, thus delivering complex research problems to the interface design of multimedia systems. In the application center is the development and access to recommendation systems which is an important component in such system, due to the immense information in channels and content proposed. The work will therefore pose and solve research questions on concrete requirements of multimedia systems for interactive TV applications in terms of utilization and context. For the practical evaluation of the proposed methods, we will provide extensions to Personal TV, a multimedia recommendation system recently released at the department of computer science with a focus on Distributed Information Systems of University of Passau, that will presents a means to provide for a mobile multimedia systems an User-Centric and personalized access.
