Supporting distributed private and public user interfaces in urban environments

Proliferation of large public displays in urban cityscape gives rise to applications distributed between public displays and mobile devices. However, real deployment of distributed applications on top of this new infrastructure is challenging as no commonly accepted architectural solutions exist to rely on. In this paper, we present a platform supporting distributed application user interfaces on interactive large public screens and personal mobile devices. We demonstrate the functionality and potential of our approach by presenting a deployment of the platform with multiple distributed applications in authentic setting in a city center. We found this platform feasible to deploy interactive, appealing services on top of, and a non-cost information pick-up service as the most appealing to users.
