On the Air is a full-body interactive installation that uses sensor data and animations. Most commonly, physically passive viewers watch an animation or a live action movie on a screen. However, On the Air uses the viewer’s distance to the installation as part of the content creation.
The installation includes a proximity sensor attached to an old radio, a pocket projector, an Arduino board, and a computer. Animated musicians are projected onto the wall walking toward and into the radio. If a visitor approaches the radio, the animated musicians speed up and run quickly into the radio and the music begins. The visitor is able to see the animated musicians walking calmly into the radio from approximately 20 feet away. As the viewer approaches the installation the animated musicians speed up and the viewer can only catch a glimpse of the musicians.
