1. A teaching system for human trajectory learning comprising: a motion sensing device for sensing a student's movement; a display; memory; and electronic means responsive to the motion sensing device to generate, during the student's movement, a student's implement virtual image sequence on the display corresponding to the student's movement of an implement set in motion by the student and to simultaneously generate a teacher's implement virtual image sequence on the display of a corresponding teacher's movement of a corresponding implement set in motion by the teacher from said memory, and to generate a virtual object image on the display to be struck by the teacher's implement virtual image sequences, such that the student may cause the student's implement virtual image sequence to imitate the teacher's implement virtual image sequence for attempting to strike the virtual object image, thereby providing an efficient motion learning sequence for the student.
