The Brain Music Lab at Georgia Tech has unique facilities allowing for online recording of EEG (brainwave), ECG (heart beat), EDA (skin response), temperature, breathing, and other measures of physiological response. We develop algorithms to convert these signals into music and sound, and engineer use-cases to apply biofeedback systems to creative, medical, and research problems. Past and current projects include brain-body music performance, epileptic seizure detection, collaborative sensing, and empathy building.
