The dissemination of large displays and personal mobile computing devices has created new opportunities for the joint use of these devices. Together these devices can enrich public spaces, promoting new and more engagement interaction mechanisms, giving users relevant information and providing important resources that can promote conversations and group activities. In this paper we explore the joint use of public displays and personal mobile computing devices, as equipments for the dissemination of personalized information that is delivered to users according to their interests and expectations. Three main aspects characterize our proposal. First, it encloses in the same system two types of devices for delivering information: mobile devices and large public displays. Second, the user only receives information of his interest point of view and the information is delivered through the most proper device. Third, our proposal combines into the same system two different perspectives: informative, providing users with information about their subscriptions and socializing, i.e. presenting, in a public display, information about the place, about users' interests and about interests of other people that visits the same place. We have developed and evaluate a partial prototype based on those principles. The results show that the system is easy-to-use, that it can support a wide range of activities and that the users recognize an added value of the system comparing to traditional approaches.
