Abstract:
1. An inertial input apparatus with six-axial detection ability, 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 an angular velocity 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 input apparatus during the rotation so as to using those for compensating acceleration signals measured along the Y-axis and thus obtaining a pitch angle basing on the compensated Y-axis acceleration signal, thereafter defining movements of an object displayed on a screen of an interactive computer by the use of the pitch angle and the angle of rotation.
