Eunoia II is an iteration of “Eunoia”, which was my first performance using a commercial EEG (brainwave sensor) headset. 

“Eunoia II” is comprised of 48 speakers with aluminum plates in various sizes, all containing pools of water. The number 48 symbolizes philosopher Baruch Spinoza’s definitions of 48 different emotions. In his book Ethics, he describes emotions as states of mind and body related to feelings and says that all emotions are derived from three primary emotions: joy, pain, and desire. He lists 48 different forms of emotions, which include hope, fear, confidence, despair, hatred, remorse, overestimation, contempt, compassion, humility, pride, despondency, shame, benevolence, anger, etc. 

For “Eunoia II”, I am using the emotional values (data) picked up by the Emotiv EPOC headset, which then gets translated into sound waves that create vibrations in the pools of water placed atop speakers. The Emotiv headset continually transmits data while monitoring my brain activity (alpha, beta, delta, gamma, theta), emotional states (excitement, engagement, meditation, frustration), facial expressions (wink, raised or furrowed eyebrows, clenched jaw, smirk), and cognitive activity.
