Visitors produce musical notes using “audio blocks” (fiducial markers) with 18 instruments, in styles of Hip-Hop, Latin, World, and Jazz. Each created note is represented as an animated shape, flowing in a real time musical stream across the table. We developed the table in OpenGL using a custom framework layered over openFrameworks. The hardware included three edge-blended projectors, a custom 12′ x 3′ Diffused Illumination multitouch table surface, and an RFID card reader log-in system. The software also communicated with a show controller to control lighting and a sign outside the room. The system was built using five computers – three were used to track and process touches and fiducial markers and broadcast that information over the network using TUIO, one computer ran the graphics and display application, and one machine ran a Max/MSP/Jitter application that communicated with Ableton Live in order to render the music and effects.
