A method of assisting a user in bringing a plurality of EEG electrodes into proper contact with the user's scalp includes receiving a signals from EEG electrodes, determining a state of contact with the user's scalp, and displaying a representation of the user's scalp and an indicator of the state of contact, the indicator positioned on the representation in a position representative of a position of an associated electrode on the user's scalp. Determining quality of contact of an electrode on a user can includes applying a reference signal to a user, receiving a measured signal from an electrode for monitoring bioelectric signals of the user, and determining a state of contact of the electrode with the user based on the measured signal and the reference signal.
