MOVING TRAJECTORY GENERATION METHOD

摘要

A moving trajectory generation method includes the following steps of: sensing a movement of a writing device in the air by a moving trajectory sensing module so as to generate a moving trajectory and then generate a moving trajectory signal; generating a virtual projection plane and a trajectory projection plane by a trajectory reconstruction unit of a trajectory reconstruction module according to the moving trajectory signal; calculating an angle between the virtual projection plane and the trajectory projection plane, and generating a transformation matrix according to the angle; transforming the virtual projection plane to the trajectory projection plane according to the transformation matrix; and projecting the moving trajectory to the trajectory projection plane so as to obtain a two-dimensional trajectory signal.
