Noor: A Brain Opera is the first fully interactive, immersive brainwave opera, in which a performer wearing a wireless EEG brainwave headset touches, gazes and walks around audience members in a 360° theater while a story is narrated. Her measured emotional states trigger videos, sound and a prerecorded libretto as her emotions are displayed as live time-colored bubbles. The opera rhetorically asks: “Is there a place in human consciousness where surveillance cannot go?” This article discusses the rationale and implementation of the brainwave opera.
