Martin Kaltenbrunner is a researcher and Ph.D. candidate working in the Music Technology Group at the Pompeu Fabra University in Barcelona, Spain. His research work concentrates on tangible and auditory user interfaces and interactive sonic systems in general. He is teaching a class on interactive systems at the department of technology at the UPF, and a workshop on tangible interaction at the Kunstuniversität Linz. Currently he is mainly working on the human computer interaction concepts of the reacTable - an electronic music instrument with a multi-touch tangible user interface, and on its open source computer vision engine reacTIVision
