Low cost tangible interfaces for music :-)
This is really funny, but serious – check out this card board type interface
Audio d-touch is a collection of applications for real-time musical composition and performance, with very special user interfaces. The collection includes a drum machine and a sampling sequencer, both are controlled by spatially arranging physical objects on 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 following video shows the d-touch sequencer and the drum machine in action:
Enjoy and stay creative
