1. A physical movement control and evaluation system comprising:

  • a source of physical movement;

    sensor means coupled to said source for deriving analog signals responsive to physical movement;

    digital generator means connected to said sensor for converting said analog signals to digital signals;

    a measuring unit receiving said digital signal and having analyzing means for evaluating motion and force measurements from said digital signals;

    a display means connected to said measuring unit and said analyzing means for displaying said evaluated motion and force measurements;

    feedback means coupled between said measuring unit and said source in parallel with said display means for introducing said evaluated motion and force measurements to said source for altering the physical movement;

    said measurement unit includes a Fourier analysis network having a separate motion analysis circuit and a force analysis circuit;

    said Fourier analysis network outputting said evaluated motion and force measurements being based on Fourier transform calculations;

    said motion analysis circuit and said force analysis circuit are coupled in parallel to said Fourier analysis network;

    said display means is selected from;

    a. visual displayb. auditing displayc. tactile displayd. printer; and

    said display means includes means for displaying said evaluated motion and force measurements as analog or digital mathematical expressions.
