I. Introduction
The visual education method of track and field sports is action demonstration. Action demonstration is to stimulate students' visual sense with specific and intuitive image, form perception, and leave fuzzy image to cerebral cortex [1]. If the teacher's behavior demonstration is not correct, it will leave fuzzy and wrong appearance to the students' cerebral cortex, form the wrong dynamic fixed concept, and affect the teaching effect. Physical education teachers' action demonstration is correct, action demonstration is faster in space, even if the process is more vivid, specific information can also show obvious action. There is no addition to the action performance. With the end of the action performance, the action state no longer exists, so it is not easy to leave a deep impression on students [2]. The application of computer multimedia vr virtual image technology can present the action that is difficult to see clearly or more complex technical action in the actual process with VR technology slow action or freeze frame picture, make up for the lack of teachers' intuitive demonstration, effectively lift the restrictions of teachers, and show more correct and standardized action than teachers [3]–[4].
