However, the electronic whiteboard can only be used to display the teaching content that has been edited in advance. However, in practical teaching, on-the-spot writing and drawing are inevitably required to assist in teaching. The current method is to write on the blackboard with traditional chalk, or use an electronic pen to write on the electronic Writing on the writing board, however, no matter what kind of writing is used, there are limitations of irregular handwriting, especially when it comes to drawing teaching, there will always be irregular drawing in manual drawing, which will affect the quality of teaching
