1. An electronic device comprising:

  • a spherical element;

    a spherical shell surrounding said spherical element; and

    at least three electrodes proximate to the inner surface of the spherical shell, wherein one electrode is positioned to enable a three dimensional position of the spherical element relative to the shell to be calculated by measuring a first capacitance between the one electrode and the spherical element and a second capacitance between any other electrode and the spherical element;

    wherein a surface area of the one electrode covers a majority of the remaining surface not covered by the other electrodes.
