User trials were prepared and conducted in the first quarter of 2014 in order to assess the appropriateness of the innovative functionalities of the second screen demonstrator developed in Y2 of the LinkedTV project. A sample installation of LinkedTV was set up at three different locations: at Rundfunk Berlin Brandenburg (RBB), Sound & Vision (S&V), and at the University of St. Gallen (USG). The LinkedTV installation included a TV showing sample content (“main screen”) and an tablet (“second screen”) showing chapters of the program as well as semi-automaticaly acquired additional information about persons, topics and places depicted in the program on the main screen. In total 24 participants took part in the trial at all three locations (9 at RBB, 5 at S&V and 10 at USG). To assess the appropriateness of the LinkedTV features, the trial participants were provided with a “hands-on” opportunity to use the LinkedTV Application and were observed while using the installation. The participants also filled in a questionnaire at the end of the session.
