A Demonstration of a Dry/No Preparation Electrode System for EEG

Psychophysiological assessment using electroencephalography (EEG) has previously been demonstrated to be an effective method for objectively assessing a variety of human factors-relevant states, such as mental workload and fatigue, as well as providing a mechanism for brain-computer interfaces. Wider adoption of EEG methods has been hampered by the extensive preparation and care that must be taken in order to ensure good signal quality. This demonstration will exhibit a new EEG system that is capable of recording data with no preparation, can be worn for long periods of time, and is reasonably robust in mobile environments. While still in development, this system has the potential to enable objective assessment of cognitive state in a wide variety of human factors applications.
