This paper reports on the design and implementation of BeThereNow, a public interactive information system where users are depicted immersed in various sceneries. The work is focused on the domain of info-tainment in public spaces using large displays and aims on short-time usage. The implemented system employs a mixed reality application through which users are informed about different sceneries and also create personalized digital postcards. This process is accomplished using computer vision algorithms in order to depict users and objects, while removing the background of the scene. Finally, the lessons learned from the long-term deployment of the system out-in-the-wild are presented, providing an insight on the users’ actions and reactions and feedback on future research directions.

The work reported in this paper has been conducted in the context of the AmI Programme of the Institute of Computer Science of the Foundation for Research and Technology-Hellas (FORTH). The authors would like to express their gratitude to Thanasis Toutountzis for his aid in manufacturing the rotating cube, as well as Manolis Apostolakis and Manolis Stamatakis who shaped the artistic concept and helped in the creation of the permanent installations.
