ILLUSION, a performance-based sound installation by DXARTS Ph.D. Candidate Haein Kang will be presented at two conferences:
- ICMC (International Computer Music Conference), June16-23 at NYU: https://nycemf.org/
- IEEE-GEM (IEEE-Game, Entertainment, and Media), June 19-22 at Yale University: https://www.ieee-gem.space/
The electrophysiological response of the brain is a substance of mental activity, and this project uses the neural signal as a medium of art by employing the EEG-based brain-computer interface(BCI). With current BCI technology, we cannot identify the emotion. However, we can detect whether you are aware of limb movements or visual information. When you relax and block visual details while you are conscious, approximately 8-13 Hz electrophysiological signals appear in the visual cortex, which is called the posterior dominant rhythm (PDR) in neurology. In the project, the performer’s PDR activates the cellular automata algorithm to produce rhythmic sounds reminiscent of raindrops.
Blinking, the simple movement of closing and opening your eyes divide the visual world into light and darkness. The BCI system turns the repetitive gesture into the musical rhythm. When you close your eyes, you can see the world imaged by sounds. ILLUSION is an instrument propelled by the mind and the experience of a moment of obscurity.
