Visualising Electromagnetic Fields

This project set out to explore the world around us that is increasingly populated by invisible phenomenon. Most of the modern technology that we use is sometimes invisible. As interaction designers, we constantly talk about them and use them to shape experiences. This project provides a visual framework with which to visualise these unseen phenomena, to enable open dialogue and communication between many disciplines and shared personal interests.

Electromagnetic Fields (EMFs) are invisible to humans but they exist around all devices with electrical and magnetic parts. Using custom software, long exposure photography and stop-frame animation, a light-painting technique was developed that captured and visualised the EMF around everyday objects like our laptops and radios.

Collaboration with: Shamik Ray.

A short video was created to communicate our research and our experimentation.

This looping animation comprises of over 100 60 second exposures, taking many hours to capture before they could be edited together.

Camera rig and lighting test were conducted throughout the project.
