Ars Electronica Futurelab guest artist Golan Levin came up with a totally new approach to the visualization of sounds in a multi-user augmented reality system.

The Hidden World of Noise and Voice installation took a playful approach to the new technologies of augmented reality. Visitors outfitted with data glasses got a glimpse into a mysterious parallel world in which words and sounds become visible. These utterances seemed to flow out of the mouths of fellow participants and assumed a wide variety of forms depending on the sounds’ volume, frequency and pitch. At the center of the installation was a table upon which virtual objects casted shadows that could also be seen by the surrounding audience of non-participants not equipped with data glasses. These special see-through data glasses were custom developed for the project by the Ars Electronica Futurelab.

Here, for the first time, dynamic objects were generated as part of an augmented reality application. The sounds and their shadows were computed in real-time and depicted in a mixed reality environment.
