Abstract
MoodMixer is an interactive installation in which participants collaboratively navigate a two-dimensional music space by manipulating their cognitive state and conveying this state via wearable Electroencephalography (EEG) technology. The participants can choose to actively manipulate or passively convey their cognitive state depending on their desired approach and experience level. A four-channel electronic music mixture continuously conveys the participants’ expressed cognitive states while a colored visualization of their locations on a two-dimensional projection of cognitive state attributes aids their navigation through the space. MoodMixer is a collaborative experience that incorporates aspects of both passive and active EEG sonication and performance art. We discuss the technical design of the installation and place its collaborative sonication aesthetic design within the context of existing EEG-based music and art.
