Abstract
A method and a system for motion tracking, capable of tracking a trajectory of a movable object by an architecture having at least three accelerometers arranged in a predefined structure. The trajectory, displacement and rotational angle of the movable object are determined by ways of extrapolation, numerical calibration and vector transformation according to the acceleration signals detected by the at least three accelerometers.
