Frequency and Volume
It is a large-scale installations in public space done by Rafael Lozano-Hemmer. His work encourages both social interaction and audience participation through the deployment of new technologies.
On entering the space, participants’ shadows are cast on the wall. Monitored by a video tracking system, each shadow tunes in to a radio frequency, changing channels as it moves around the gallery. The outline of a projected shadow affects the tuning, while its size controls the volume, thus the human body becomes an antenna able to tune into different frequencies. The resulting sound environment is a continuously evolving composition created by multiple contributors.
