Modelling User Behaviour and Experience – The R2D2 Networks Approach

The rapidly increasing importance of multimedia services delivered over telecommunication networks has heightened the need for technologies that adapt efficiently to users’ needs. It is of particular interest to understand users of such services. This paper proposes a unified approach to modelling users’ behaviour and experiences in the context of new multimedia services. Static information on users’ behaviour is integrated with users’ real-time feedback about their experiences. A unified user profile is used for implementation of a media-aware, user-dependent, self-adaptive network resource manager. Our first experience shows that such a unified approach might be beneficial for network and service providers. The tool for gathering real-time user experience, we propose, might also be useful in other contexts, such as personalised content recommender systems.
