The idea behind the "Atlas of Rome" 35m wide projection wall is to encourage passers-by to experience multiple views on the city they live in, and to explore the visions that architects, artists, institutions and, in general, other people have had on urban spaces. The project's ambition is considerable: several other international cities have been contacted to create other instances of the Atlas, with the idea of creating a data visualization system that interconnects remote urban spaces. Imagine, as an example, a data visualization through which people could interact in real-time with the people in other cities of the world.
All data shown is based on an online content management system that was set up as a collaborative process with the city's institutions, groups and individuals, and which allows all these stakeholders to add or alter any multimedia information about on their projects, actions, visions and urban plans.
This information is represented by 4 different data visualizations which are rendered onto a large-scale architectural installation. In the "Linearity" visualization, the visions take the form of mechanisms grabbing their life energy from the interactions among individuals and themes. Spheres represent visions and, while moving, they are constantly fed from the themes that they explore. In "Neo Map", circles represent the visions, dislocated according to their reciprocal geographical locations and connected by subjects. In "Bridges" visions orbit around the respective themes, in a cyclic sequence. Visions and themes dynamically show bridges and interconnections, according to he subjects and actions that they share. Lastly, "Timescape" transforms the passage of time into a landscape. Visions are represented in their time dimension, occupying spaces that are proportional to their duration and sequence. A geography defined through time and correlation is made visible and interactable.
12 different computers were used to drive the continuous 35m-wide projection, the server components and the control logics for the multi-touch screens. The technologies involved have been developed by FakePress and will soon be released as Open Source software (GPL2 license).
