It's designed to assist in the development of real-time music and multimedia applications. EyesWeb supports the user (i) in the development and experimenting of computational models of expressive content communication and of gesture mapping strategies, (ii) in fast development and experiment cycles of interactive performance setups.
reacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers attached onto physical objects, as well as for multi-touch finger tracking. It was mainly designed as a toolkit for the rapid development of table-based tangible user interfaces (TUI) and multi-touch interactive surfaces. This framework has been developed by Martin Kaltenbrunner and Ross Bencina at the Music Technology Group at the Universitat Pompeu Fabra in Barcelona, Spain as part of the the reacTable project, a novel electronic music instrument with a table-top multi-touch tangible user interface.
