LAb[au] and its interactive installation '12m4s'

The installation '12m4s' is an interactive audiovisual installation representing human flows by generating out of visitors' main parameters (position, orientation and speed) a visual ( 3d particles ) and sonic (granular synthesis) dynamic scape in real-time. To achieve this result, the installation uses 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). These different tracked data influence a graphical vector-field projected on the entire surface of the screen (foreground), where each of its vectors reacts to a visitor's movements while 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 t! o move through the vector field, while trying to find their path.

For example: a visitor is passing by the installation, s/he is followed by a visual and sonic trace, but 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 open ups to collective interaction.

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 space.
