Abstract
Media facades in urban spaces offer great potential for
new forms of collaborative multi-user interaction. We
present a way to directly interact with facades at-adistance
through live video on mobile devices. We extend
the Touch Projector interface to accommodate
multiple users by showing individual content on the
mobile display that would otherwise clutter the facade's
canvas or distract other users. To demonstrate our concept,
we built an application that allows for simultaneous
painting on a facade. We gathered informal feedback
during the ARS Electronica Festival in Linz, Austria
and found that our interaction technique is (1) considered
easy-to-learn, but (2) may leave users unaware of
the actions of others on the same canvas.
