This paper presents insights and learning experiences on the development of an integrated group recommender system in the European FP7 HBB-Next research project. The system design incorporates insights from user research and evaluations, media industry players, and European HbbTV standardization efforts. Important differences were found between providing(More)
Every now and then existing methods in the User-Centered Design (UCD) process evolve and new methods are being introduced. In this position paper we discuss our new approach for studying communities within the new media landscape. First, this new approach contains ways to improve the relations between the designers, researchers and developers on the one(More)
In this paper, we present a better understanding of the contextual aspects that determine TV and video viewing situations in the home. The results can be used to design recommender systems algorithms and interfaces for TV and video content that better fits with different viewing situations in the home. This is achieved by taking into account these typical(More)
This paper presents an explorative investigation into households? uses of traditional broadcast television (TV) and more recently introduced video-on-demand (VoD) services. More specifically, we explain how each way of viewing TV and video content relates to different viewing situations in the home. We conducted in-home interviews with seven households in(More)
— The scope of this paper is the interdisciplinary measurement and modeling methodology of Quality of Experience (QoE) when playing a mobile location-based massively multiplayer online role-playing game (MMORPG) that places the virtual world on top of the real world using the user's location. The paper introduces the implementation of a re-usable mobile QoE(More)
Today, using second screen devices while watching TV is quite common, whether related to what happens on TV or not. One area of research looks at using second screen devices to support social interaction. While most research in this area focuses on supporting social interaction between remote viewers, in this article, we focus on social interaction between(More)
The well-established Quality of Service and the relatively recently emerged Quality of Experience research topics are unquestionably linked, yet to date little effort has been invested in the study of their precise correlation and mutual reciprocity. This paper examines the impact of three representative QoS-related parameters on user QoE in the particular(More)
This paper identifies important requirements for second screen (game) companion apps. Participants were invited to create their own (board) game to play alongside a TV show. Afterwards they were interviewed about their experience. Analyses of the games and interviews lead to some valuable insights in what contributes to an engaging "TV game". Lessons(More)
