Martin Kaltenbrunner is a Human Computer Interaction Designer, currently finalizing his Ph.D. at the Pompeu Fabra University in Barcelona, Spain. Recently he has been mainly working on the interaction design of the reacTable - a tangible modular synthesizer based on a multi-touch surface. He is author of the open source tangible interaction framework reacTIVision and the related TUIO protocol, which has been widely adopted for open source multi-touch applications.

reacTIVision is an open source, cross-platform computer vision tool for the fast and robust tracking of fiducial markers attached onto physical objects, as well as for multi-touch finger tracking.

The reactable is a collaborative electronic music instrument with a tabletop tangible multi-touch interface. Several simultaneous performers share complete control over the instrument by moving and rotating physical objects on a luminous round table surface. By moving and relating these objects, representing components of a classic modular synthesizer, users can create complex and dynamic sonic topologies, with generators, filters and modulators, in a kind of tangible modular synthesizer or graspable flow-controlled programming language.

After its overwhelming success on Youtube and since the Icelandic singer Björk has incorporated the instrument during her last Volta world tour, the reacTable has become widely known to the general public.
