ABSTRACT
Over the last few years, the television viewer has been assuming an ever increasingly active behaviour, creating new habits in face of television using the technology available. In this perspective, the mobile device has been playing a key role as second screen, into which the plot leaks or where complementary information is presented. The perfect conditions for the creation of a medium, where knowledge related to television shows can be created and shared, are then in place. This research takes advantage of this opportunity, starting with a preliminary study to access the needs and expectations of potential users. From the gathered results, a mobile application that makes available complementary information for the television shows through automatic content recognition was conceptualised. A proof of concept was implemented and, following the ensuing laboratory evaluation, it was possible to infer about the optimisation of the television experience and the sharing of information about the shows between viewers.
