How the user behavior is affected by the use of secondary screens on interactive television: An affective usability dimension

Abstract:

Television (TV) has deeply influenced on human behavior so far, however Internet is changing the way that people interact with TV. One important change has been leveraged by the wide adoption of small and powerful mobile computers, such as smartphones and tablets. It has raised the opportunity to employ them in multi-user and multi-device interactive television (iTV) scenarios. Two important research questions are: Do these devices compete or cooperate for the attention and the benefit of the user? Most notably, how multi-device interaction is appreciated in multi-user scenarios? Previous research has raised and considered the above research issues and questions for dual screen set-ups in the work environment. Broadly it is explored multi-device user interface configurations in the context of a leisure environment and for entertainment applications. Our objective is to measure the affective usability dimension in the field of iTV and how this kind of new conceptual interaction can change the user behavior. In this paper, a system to control and share the TV content with a smartphone or tablet is defined and the methodology to evaluate this system is presented. © Springer-Verlag Berlin Heidelberg 2013.
