The increasing number of media facades in urban spaces offers great potential for new forms of interaction – especially for collaborative multi-user scenarios. In this paper, we present a way to interact with them through live video on mobile devices. Users can directly interact with the facade shown in the viewfinder. Additionally, we use the mobile display to show individual content that would otherwise clutter the facade's canvas or distract other users. To demonstrate our concept, we built two collaborative multi-user applications: (1) painting freely on the facade and (2) solving a 15-puzzle. We tested the applications during the ARS Electronica Festival in Linz, Austria and found that users consider this interaction as easy-to-learn and that they enjoy collaborating or competing with others.
