1. A system for measuring the speed of a person, said system comprising:

  • a plurality of accelerometers and rotational sensors disposed in the shoe of said person, said accelerometers configured so as to provide acceleration signals corresponding to accelerations associated with the movement of said shoe as said person takes a step, said rotational sensors configured so as to provide angular signals corresponding to the angle of said shoe about an axis of a three dimensional translational coordinate;

    a calculator coupled to said accelerometers and said rotational sensors configured so as to receive said acceleration signals and said angular signals, said calculator adapted to measure the distance traversed during each step and the speed of said person.
