From Martin Wehl on vimeo:
The project is a small prototype exploring the sonification* of elevation data. It was created within a course on the use of audio within interaction design at my university. I wanted to keep the sonification set up as simple as possible hence I designed the higher elevation to coincide with a higher note. The topographic model used for the sonification is a fictional landscape. The layers were created with laser cut poplar plywood and painted with conductive ink to enable touch sensitivity. Hook-up wires are located beneath each layer, connecting the surfaces of conductive ink with an arduino leonardo board and an additional adafruit mpr121 touch sensor. Every touch generates an audible note in real-time via a web browser that utilizes the tone.js; an amazing library for programming your own synthesizers.
