Information Age

Fiducial Voice Beacons is a large-scale interactive artwork made especially for the Information Age gallery at the Science Museum by the artist Rafael Lozano-Hemmer.

Lozano-Hemmer’s artwork consists of 40 interactive light beacons located across the ceiling of the gallery. Each beacon holds a sound recording that is transformed from audio frequencies into beams of light.

The sound recordings come from poets, scientists, engineers, artists, philosophers and other voices from the past and present of modern communication. This archive brings together pioneers who have influenced our understanding and use of information technologies.

Gallery visitors can select, listen and replace the sound recordings with their own message using a free downloadable app. The work changes constantly as the message of one visitor replaces another.

Lozano-Hemmer describes the work as a kind of switchboard or cloud of voices and ideas that mirror the content of the gallery below.

About the artist

Rafael Lozano-Hemmer was born in Mexico City in 1967 and now lives and works in Canada. Many of his artworks use new technologies and custom-made physical interfaces that encourage public participation; the audience members are asked to actively participate, and their contributions become an essential part of the artwork.

Lozano-Hemmer has won several awards, including two British Academy of Film and Television Arts Awards for Interactive Art and the Prix Ars Electronica Golden Nica. He is a faculty associate of the Graduate School of Design at Harvard University. His work has been commissioned for the Millennium Celebrations in Mexico City (1999), the 50th Anniversary of the Guggenheim Museum in New York (2009) and the Winter Olympics in Vancouver (2010).
