As its title suggests, the interactive urban installation “12M4s” is based on a space of 12M and a time of 4s, corresponding to a human walking at ordinary speed the distance of 12m. In this space-time continuum, human movements and flows are tracked to generate a visual (particles) and sonic (granular synthesis) scape in real-time, out of their main parameters (position, orientation and speed). The result, this ‘particle synthesis’ is projected on a ‘Mylar’ screen fusing projection and reflection while building a common space in between the digital and the body spaces.

about 12m4s

As its title suggests, the interactive installation “12M4s” is based on a space of 12M and a time of 4s, corresponding to a human walking at ordinary speed the distance of 12m. In this space-time continuum, human movements and flows are tracked to generate a visual (particles) and sonic (granular synthesis) scape in real-time, out of their main parameters (position, orientation and speed). This result is achieved via two different tracking techniques: firstly, image recognition is used to create spatial sounds (diffused through 8 speakers disposed along the 12m installation) and secondly, ultra-sound sensors are used to create visual echograms of the space (projected as background image along the 12m screen). The data captured through these sources influence a graphical vector-field projected on the entire surface of the screen (foreground), where each vector reacts to a visitor’s movements by taking his/her orientation. Furthermore, graphical and sonic objects emerge at the point (location) where movement is recognized. Once created, these sonic and graphical elements start to move inside the vector field, negotiating their way out according to the vectors orientation.

For example: a visitor is passing by the installation, s/he is followed by a visual and sonic trace. As soon as s/he changes direction or produces any other movements, s/he creates turbulences. According to this principle, the visitor can even more actively paint with his/her movements a sonic and visual space on the 12m surface, as it opens up to collective interaction.
