The goal of City Murmur is to show how different media differently describe the urban space through the attention that is payed on each street of a city. A new media geography has been generated intersecting the media scape with the geographical reality of the city.
On-line newspapers, information agency, blogs and personal websites, thematic media are monitored to highlight the pattern of perceptions on the urban space. This monitoring activity leads to the creation of an atlas that will produce - in real-time - different maps based on news sources, themes, and time. The atlas allows users to understand the urban space as a function of media attention and biases and social and cultural diversity of the city itself.
CityMurmur aims at addressing maps and diagrams not as passive representation of realities but as tools for interpretation and action. It wants to build a time-based narration, an historical archive of media coverage of the urban space which is able to reveal some hidden dynamics useful for city policy support, critical media analysis, and sociocultural research.
City Murmur has been developed during the 2008 edition of Visualizar, at Medialab Prado by Giorgio Caviglia, Michele Graffieti, Samuel Granados Lopez, Daniele Guido, Marco Quaggiotto, Donato Ricci, Gaia Scagnetti.
Initially focused on the city of Madrid, it has been also applied to New Orleans, in occasion of the 2009 SiGGRAPH exhibition, where it has been invited to participate in the Emerging Technology session.
