New Ways of Knowing Ourselves. BCI

Facilitating Artistic Exploration of Our

Biology

Laura Jade and Sam Gentle

Abstract As rapidly advancing technologies become more widely available, hav-

ing access to tools that collect biometric data and in particular BCI technology, is

providing artists with new ways of exploring our biological selves as well as creating

new modes of audience interaction. Brainlight is a large illuminated interactive sculp-

ture that integrates biology, lighting design and BCI technology to explore the hidden

aspects of our minds. The installation is controlled with a wireless EMOTIV EPOC+

EEG headset that detects live neural activity which is translated into a light display

within the brain sculpture. In real time it visualises the brain frequencies of Theta

(3.5–7.5 Hz) as green light, Alpha (7.5–13 Hz) as blue light, and Beta (16–32 Hz)

as red light. Previously, in more traditional art, when an audience views an artwork

their own psychological process would be a passive, hidden, private experience. The

aim of Brainlight is to harness the brain as the creator of an interactive art experience

where no physical interplay is required except for the electrical activity of the mind.

The project exposes some key developments in the use of BCI technology for artis-

tic purposes, such as how to accurately collect and process EEG data aesthetically,

and what license the artist can take with this data in order to facilitate meaning or

allow space for the audience to bring their own meaning to the work. This chapter

will explore these developments and outline the collaborative process behind the

research and development of the work and the contexts in which it has subsequently

been exhibited and used by the public.
