1. A method of exercising control of an object shown upon a display by brain wave monitoring, wherein a brain of an individual being monitored responds to command selections that are shown upon said display, and thereby moves the object shown upon the display to a selection desired by the individual, said method comprising the steps of:

  • a) monitoring said brain waves of an individual; and

    b) computer processing the monitored brain waves in accordance with step (a) in order to control said object shown upon said display, and further including the steps of;

    i) monitoring said brain waves at a comprehensive set of head locations;

    ii) selecting specific head locations to be utilized to control said object;

    iii) feeding said brain waves from said selected head locations to a computer which utilizes temporal and spatial filtering methods to obtain a plurality of object control signals;

    vi) using an algorithm to combine said plurality of object control signals to control movement of said object upon said display;

    v) storing data consisting of brain waves from all of said monitored head locations, said control signals derived from the selected head locations, and movements of said object; and

    vi) periodically analyzing said stored data of step (v), using results of said analysis to modify said selection of specific head locations, said plurality of object control signals derived in step (iii) from said selected head locations, and said algorithm of step (iv), so as to improve control of object movement.
