1. An inertial sensing input apparatus, comprising:

  • an accelerometer module, structured with at least three accelerometers for detecting accelerations in three perpendicular directions with respect to a Cartesian coordinate system of X-, Y-, and Z-axes; and

    a gyroscope, used for detecting a rotation measured with respect to the Z-axis;

    wherein, an angle of rotation is obtained by integrating the angular velocity of the rotation detected by the gyroscope while calculating a centrifugal force as well as a centripetal force exerting upon the inertial sensing input apparatus at the moment of the rotation so as to using those for compensating acceleration signals measured along the X-axis and the Y-axis and thereafter defining movements of an object displayed on a screen of an interactive computer by the use of the compensated acceleration signals.
