ABSTRACT The screen, eternal windows to other worlds, in the last years it has gone from a faithful image support to transform into an authentic viewer through which everything happens, but nothing remains. Through it runs that which has lost tangible presence in our wide visual repertoire, while it has repositioned our experiences and sensations regarding the environment and images that surround us. It has modified our life’s spaces, contributed to condition a new space-time lecture that has to do with concurrency, with contraction, with life in real time, where diverse scenarios are a constant and therefore the possibility of worlds and “multiple” cities, and the creation of virtual communities, a reality. The contemporary city it’s lived through and on the screens, at the same time, it also shelters them; in a way that the visual speech and the critic art that reflects and questions the role of this artifact in contemporary societies which results in a real revitalization for the experiences that, through this speech, are lived fundamentally in common spaces. Away from demonizing it, such a questioned apparatus, which soon will stop showing just as we recognize it today, the research presented here, seeks to arrange it in its proper dimension about their conditioning role in and for public spaces. Keywords: Screen, public space, virtual cities and communities, critic art.
