Last weeks Something For The Weekend we showed you a video of Mark Mosher playing the AudioCubes from Percussa. AudioCubes are a platform for audio-visual creation and exploration. They are a collection of beautifully designed and hand-made objects, each containing its own self-powered wireless computer system. However, this week we want to show you a video from Btrax using a interface based on the reacTIVision software.
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.
If you want to know more what reacTIVision is used for, here is a list of music interfaces built with this software.
