MOVING TRAJECTORY GENERATION METHOD
First Claim
1. A moving trajectory generation method, comprising the 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 signal to the trajectory projection plane so as to obtain a two-dimensional trajectory signal.
