"The more clearly you understand yourself and your emotions, the more you become a lover of what it is."- Baruch Spinoza
“Eunoia” is a performance that uses my brainwaves -- collected via EEG sensor-- to manipulate the motions of water. It derives from the Greek word “ey” (well) + “nous” (mind) meaning “beautiful thinking”. EEG is a brainwave detecting sensor. It measures frequencies of my brain activity (Alpha, Beta, Delta, Gamma, Theta) relating to my state of consciousness while wearing it. The data collected from EEG is translated in realtime to modulate vibrations of sound with using software programs. EEG sends the information of my brain activity to Processing, which is linked with Max/MSP to receive data and generate sound from Reaktor." - Lisa Park
"Eunoia II is outfitted with 48 vibration pools, inspired by the 48 emotions philosopher Baruch Spinoza outlined in his book, Ethica, like frustration, excitement, engagement, and meditation. Each speaker vibrates according to Park's brain wave-interpreting algorithm, which tranforms intense signals from Park's Emotiv EEG headset into intense vibrations in the pools of water atop speakers. The modulation of the sound (volume, speed, panning) occurs in real-time in response to her emotional values detected by EEG headset. Here, Park is literally putting her inner struggles on display, and the whole show depends on how she deals with her feelings. The calmer she is, the less vibrations of the sound happen."
