Mind-Modulated Music in the Mind Attention Interface

Abstract

A recent study of electroencephalogram (EEG) activity associated with musical cognition has suggested a correlate for the amount of active musical processing taking place in the brains of musicians. Using a version of this measure, we have built a new brain computer interface which harnesses the "natural" brain activity of musicians to mold and modulate music as it is being composed and played. This computer music instrument is part of a system, the Mind Attention Interface, which provides an interface to a virtual reality theatre using measures of a participant's EEG, eye-gaze and head position. The theatre itself, and its spatialised sound system, closes a feedback loop through the mind of the participant.
