ABSTRACT:
An inertial sensing method is disclosed, which is capable of detecting tilting of an inertial sensing apparatus with respect to a specific level surface while using the detection for defining/controlling movements of a cursor displayed on a display, In a preferred aspect, as it is capable of acting as an hand-held input device, a swing of a hand holding the inertial sensing apparatus can be detected thereby and is used for controlling a page change of a display. Operationally, a micro inertial sensing module of the aforesaid inertial sensing apparatus detects changes of gravity caused by tilts of the inertial sensing apparatus and then generates inclination signals accordingly while enabling a wireless transmitter to send the same to a micro processing unit where the inclination signals are filtered and then compared with predefined datum signals so as to enable a cursor control circuit to define/control movements of a cursor displayed on a display according to the comparison. In addition, an effect of vibration measured along an axis of a Cartesian coordinate system of X-, Y-, and Z-axes defining the inertial sensing apparatus can be eliminated by the use of variations of signals measured along other axes of the Cartesian coordinate system. Preferably, by using two Y-axis accelerometers of the micro inertial sensing module to measure a difference of centrifugal forces detected respectively thereby, the adverse affection of centrifugal forces exerting upon the Y-axis can be eliminated.
