Le Corbusier in Bogota 1947-1951, was an exhibition that presented the contrast between the urban development proposal of Le Corbusier in the fifties and the current city. A system has been developed in order to provide the audience with an interactive 3D visualization in the exhibition. This paper describes the focus-context model used to show the differences between the current state of the city and the design by Le Corbusier, as well as some aspects about human-computer interaction to design the user experience based on audience assessments. The exhibition was held in Bogota from April to June, 2010.
