Footfalls (2006, by Golan Levin and Zachary Lieberman) is an interactive audiovisual installation in which the stomping of the visitors' feet creates cascades of bouncy virtual forms.
Stomping sounds produced by the visitors' feet are detected by microphones under the floor. These signals govern the number of virtual objects that fall from a six-meter high projection. The harder the visitors stomp, the more items are dislodged from above. Using their silhouettes, visitors can also "catch" and "throw" these projected objects around.
Footfalls was commissioned in July 2006 by the NTT InterCommunicationsCenter (ICC), Tokyo. The documentation shown here is from a presentation of the project at Centre Beaulieu, Nantes, France, in May 2008. Footfalls was developed in openFrameworks by Tmema (Golan Levin and Zachary Lieberman).
