This report documents technical and research efforts to systematically compare the performance of three mobile electroencephalographic (EEG) systems within the Naval Health Research Center's Physical and Cognitive Operational Research Environment. Twelve healthy subjects performed classic auditory and visual oddball tasks in both static (sitting) and dynamic (walking) conditions while wearing each mobile EEG system (subjects also wore a gold standard wired EEG system in the static condition only). Results indicated that all three mobile EEG systems were capable of acquiring high quality EEG signals; however, there were significant differences based on system preparation times, ratings of pain and comfort, and number of trials required to achieve measurement quality comparable to the gold standard system.
