Abstract
A method which is accurate and yet relatively simple, rapid and inexpensive for estimating 3-D coordinates of EEG (electroencephalograph) electrode positions on the head. The electrode positions of any number of scalp electrodes placed according to the standard 10/10 electrode position system are computed by a computer system based on 14 manually measured inter-electrode distances and 9 electrode-to-skull landmark straight-line distances. The measurements are made manually using digital calipers.
