	abstract = {Interactive tabletops offer a unique opportunity for exploring home videos and photos. Nevertheless, there are still a number of unexplored challenges for effectively providing support for collocated group interaction around media. This paper reports on a user study involving 24 users, intended to better understanding the challenges ahead. Our volunteers (in couples) evaluated our media sharing application prototype, providing valuable feedback with regards to three key challenges: metaphor, digital ecosystem, and level of control. First, users appreciated the selected metaphor of physical photos, but without relinquishing software support, such as alignment and distribution of media items. Second, vertical auxiliary screens helped in supporting a bigger number of users and providing more comfort and a better viewing angle and stance. Third, the nature of the task (either storytelling or random exploration) had a strong influence on the control capabilities to be provided by the application. Fourth, personal spaces within the tabletop were useful for allowing independent navigation. We consider these results as relevant for the future developments of home media sharing applications for the living room.},
