Case Studies For Visions

Creates virtual networks of real places with the use of QR codes which are used to tag buildings and urban sites. These codes can be read via mobile phones. The user shoots the codes and logs them in to

Anyone can tag places and create a denCity-site. All relevant information and data links concerning the particular user-request are released cartographically and depend on the desired degree of locality.

"This information exchange layer, through the tags's crosslinkings and referencing among each other, features a multidimensionality which oscillates between the local and the virtual.The tags are digital yet visible marks in the city. At the same time virtual and physical addresses. They establish interfaces between locality and virtuality. (

Art in Odd Places

Providing an opportunity for people in the art world to explore and examine the role public space plays in our society. Using a map, the audience move about the Lower East Side revealing art in places throughout the community.

AIOP 2006 projects examine current public space potential, spaces that have recently been privatized, and the boundaries of public space.

On the interactive map available online (shown here), one can understand the relationships between authors, location, and projects, placed in three correspondent columns, by rolling over each one of the instances.

Sensity is part of "The Emergent City" series of works by Stanza. In this 3rd version of Sensity, Stanza aims at visualizing the dynamic data around his district as an audio visual artwork.

Sensity artworks are made from the data that is collected across the urban and environment infrastructure. A network of sensors, some fixed, and some embedded, collects data which is then published online. The sensors then interpret the micro-data of the interactive city. The output from the sensors displays the emotional state of the city online and the information will be used to create installations and sculptural artifacts.

These artworks made will represent the movement of people, pollution in the air, the vibrations and sounds of buildings, they are in effect emergent social sculptures visualizing the emotional state of the city.


The work is based on the movement of pedestrians on a public space. Some pedestrians walk only on the sidewalk and use the pedestrian crossing for crossing the street, other pedestrians freely make shortcuts on the formally imposed traffic situation. Pedestrian is an artwork in public space that reflects on this movement. It visualizes the real movement of people, and adds a virtual movement based on the assumption that people's mind is not subject to gravity or any other physical limitations.

The movement of pedestrians is recorded with a camera from a high place like the roof of a building. A pattern of movement of the pedestrians is extracted by reworking this recording frame by frame with video animation software: it is as if pedestrians draw lines though the space. From this pattern, some dominant directions can be found. These directions will not be exactly what the urbanist foresaw when designing the public space at the location, but be the real flow, the real use of the city by its inhabitants.

The movement of the pedestrians could be regarded as force-vectors through the space. A person's trajectory from A -> B is nearly never a straight line, as many obstacles are in the way (like buildings), imposed trajectories (pedestrian crossings, sidewalks) and physical limitations (gravity). At this point a question is asked: how would the pedestrians move when they were not limited by anything?

Tracing the Visitor's Eye

Fabien Girardin is a Ph.D. student in Computer Science and Digital Communication at the Interactive Technology Group at the Pompeu Fabra University in Barcelona, Spain. His current investigation explores the people perception of discrepencies in the context of collaboration supported by mobile and ubiquitous environments.

In continuation of Fabien's exploration of Flickr geotagged images, he produced the "traces" left in Flickr by tourists and citizens of Barcelona based on around 4000 images taken between October and December 2006.

A trace consists in an ordered set of geotagged images taken by one person in one day. The data and visualizations remain somewhat raw, but there might be a potential to define and confirm patterns of how tourists navigate the urban space. The maps do not carry the sense of time yet to highlight when and where the traces start and end.
