an interactive table surface. Each object represents a sound, and its position with respect to the surface is mapped to certain playback parameters. For example, the horizontal position of an object represents the timing of the sound. The system is extremely low cost
and now it can be freely and fully downloaded from http://www.d-touch.org/audio. All is needed to get audio d-touch to work is a standard computer (PC or Mac) with a webcam and a printer.
The audio d-touch interactive surface consists of a simple printed piece of paper. The movable physical objects are marked using labels, also printed on normal paper. The computer observes the blocks and the paper through a low cost web-cam, and thanks to the d-touch marker recognition algorithm it can localize them precisely. The information about the position and orientation of each block is used to control a digital audio synthesis process. The system was designed to be extremely low cost, robust and easy to set up, which makes it possible to fully and freely release it for download.

The release of audio d-touch is itself part of a research project about novel computer interfaces. Our aim is to advance the field by gaining insight on how tangible interfaces may be used in the real world. Please help us by trying out the applications, letting us know what you think and spreading the word about audio d-touch! To inform our research we remotely record usage data from the system, in the respect of our users' privacy: we do not record images, but only the positions of the objects in the interface and the sounds recorded on them (all details are available on the download page on d-touch.org).

collaboration resulted in the incredibly fast production of a number of prototypes in 2003, thanks also to the great encouragement that they received from the Media Engineering Group at the University of York. In the following years Enrico continued to develop audio d- touch as a side activity, while his day job as researcher at Media Lab Europe and MIT Media lab focused on mobile devices. Part of the original d-touch recognition system was adopted by the colleagues and friends developing Reactable at UPF in Barcelona. In 2006 the Italian composer and cellist Giovanni Sollima became interested in the sequencer and has used it in a number of public performances right up until the present day. In early 2009 Matteo Giaccone and Olivier Küng joined Enrico, who in the meantime had moved to the Media and Design lab at EPFL, and their enthusiasm and technical contribution was key for making audio d-touch truly multi-platform and available for download.
