Abstract
An improved brain wave electroencephalograph (EEG) method measures the physical positions of EEG electrodes applied to the subject's scalp. A set of standard cross-directional lines are obtained to provide measurements of the subject's head and a computer system automatically defines the subject's head shape according to predetermined head shape classes. The position of the electrode on the subject's scalp is then determined by scaling the measurements of the subject's head to a head model of the same head shape class.
