Together with Laura Malinverni, I participated in the Campus Junior event “La universidad y yo” at Universitat Pompeu Fabra. We invited teenagers to explore possibilities of rethinking and changing learning spaces through the use of a mixed reality system. During a brainstorming activity, the participants reflected upon which learning spaces had caught their attention and how they would like them to “transform”. After that, they created first their own ideas for graffitis with pencil and paper. The graffitis were then digitalized and the teenagers explored their application in relation to the physical space of the university campus.
