1. An eye tracking interface system for controlling task-performing functions comprising:

  • a detecting device adapted to detect bio-electromagnetic signals generated by eye movements;

    a first processor adapted to receive said detected bio-electromagnetic signals and, in response thereto, assigning tokens from a set of symbolic tokens corresponding to eye movement classifications, thereby producing a plurality of tokens representative of said bio-electromagnetic signals;

    a second processor adapted to receive said plurality of tokens, recognize patterns of tokens, and generate command signals based on said recognized patterns;

    where said command signals control task-performing functions.
