1. A three-dimensional inertial sensing method for cursor control, comprising the steps of:

  • using a micro inertial sensing module to detect an acceleration of gravity for generating a raw inclination signal accordingly;

    low-filtering the raw inclination signal for obtaining a stabilized inclination signal;

    registering an initial signal of the micro inertial sensing module;

    calculating a signal variation amount basing on the raw inclination signal, the stabilized inclination signal so as to compensate the raw inclination signal using the signal variation amount;

    calculating the difference between the compensated inclination signal and the initial signal; and

    mapping the differences as a coordinate signal for controlling the movement of a cursor displayed on a display.
