I think I have managed to find a way to gather my research and my passion for psychogeography. Focusing on how information technologies could help us to reappropriate urban's life is definetely my interest... Debord, in 1955, defined psychogeography as "the study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behaviour of individuals ".
My stance is that IT could trigger new behavior in urban life (howard rheingold's smart mobs, social texting, location-based awareness services) that may encourage people to live new urban experiences.
I am trying to gather ideas about that, I begin to write something up...
