Experimental Interaction Hongik 2010

Experimental Interaction
(Physical media)
Preface and Introduction

Cymatics is the study of visible sound and vibration, typically on the surface of a plate, diaphragm or membrane.

Direct ocular viewing of vibrations involves exciting inorganic matter such as particulate matter, pastes (both magnetic and non magnetic) and liquids under the influence of sound, although recent research has extended the range of media to include organic matter and the range of viewing has been extended to include the light microscope.
The generic term for this field of science is the study of 'modal phenomena,’ named 'Cymatics' by Hans Jenny, a Swiss medical doctor and a pioneer in this field. The word 'Cymatics' derives from the Greek 'kuma' meaning 'billow' or 'wave,' to describe the periodic effects that sound and vibration has on matter.
The apparatus employed can be simple, such as a Chladni Plate (a flat brass plate excited by a violin bow) or advanced such as the CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.

This class and projects will be about the exploration of audio driven patterns and graphics with an intention to create an instalation.

Project One
Circuit Bending and Electronics
Duration 3 weeks

Each person will buy two or more battery powered electronic
audio devices. (Must be battery powered). One will be a
speak and spell machine the other will be up to you.

Week One – Introduction
Week Two – Disassemble and initial tests
Week Three – Adding components for control and interaction.

Note. As well as buying electronic audio devices you will also need soldering irons and various other components.

Project Two
Signal Processing and Sound
Duration 3 weeks


Sound signals have been represented graphically for as long as graphics has existed. However with a computer added to the working pipeline its possible to envisage many new and unexplored visualizations of audio data.

The basis of motion graphics is often the relationship between sound and image. However as media breaks out of the confines of the screen new methods and approaches to audio data output are emerging.


We will take our sound source from the first project. Processes it digitally then output it three dimensionally via the laser cutting fabrication process.

Week One - Introduction
Week Two – Strategies for visualizing audio
Week Three – Digital laser output

Project Three
Duration 2 weeks

David Hall 'Ferro Interaction' 2004



Each person will choose a liquid or granular material and pipe their audio
Experiments through the material.

The end result will be a Movie presentation of their experiment.


Project Four
Real-time and interaction
Duration 6 weeks


Final Presentation
