The Reactable project started in February 2003 at the MTG, by a team led by Sergi Jordà and completed with Günter Geiger, Martin Kaltenbrunner and Marcos Alonso. We envisioned the ambitious goal of developing the best computer-based musical instrument we could imagine, without being necessarily constrained by any predefined technology. In that sense, the Reactable really started from a concept, and not from a technology. First we decided what to do, and later we discovered how to do it, and the completion of all the technologies needed for the correct conclusion of the project (such as the tracking system reacTIVision), came luckily all along the Reactable's development process.

Since 2009, the commercialization and further development of the Reactable music instrument in all its forms (tabletop, mobile apps, etc.) is being carried by the spin-off company Reactable Systems, founded by the Reactable creators (Sergi Jordà, Günter Geiger, Martin Kaltenbrunner and Marcos Alonso).
