Abstract__ Background Brain-computer interfaces BCI use electroencephalography EEG to interpret user intention and control an output device accordingly. We describe a novel BCI method to use a signal from five EEG channels comprising one primary channel with four additional channels used to calculate its Laplacian derivation to provide two-dimensional 2-D control of a cursor on a computer screen with simple threshold-based binary classification of band power readings taken over
