Recommendations to improve user experience in second screen applications: a case study

This article presents a case study that uses recommendations from the literature of Human-computer interaction (HCI) for adaptation of a second screen application entitled DFapp, in order to improve the user experience. The paper explains how an application was tested including the implementation of HCI recommendations, with final users. A set of guidelines sourced from recommendations found in the literature permitted the improvement of the application's interactivity and were essential to this process. With this study, we intend not only to contribute to the development of a better understanding of the combined use of TV and second screen in diverse environments, but also to provide support literature for second screen application developers. As a result, it is presented recommendations concerning not only general concepts for HCI, but also a core recommendation for second screen applications.
