In terms of taking the stroke order of the Chinese characters, many people read the beginning and the high school, and the teacher points to the desk to write, so that the 'drawing reverse stroke' always exists, namely the stroke order has problems, and the stroke problem of writing is difficult to change. Therefore, in the examination of primary school Chinese, the stroke order of the Chinese characters occupies a plurality of scores, and many parents are always very headache, which seems to be changed by the rules taught on the book.

Therefore, many people are developing various corresponding teaching aids to solve the above problems, for example, chinese patent CN102800216 discloses a method and device for learning chinese characters, which is used to help beginners write chinese characters in correct writing order. The method comprises the following steps: determining Chinese characters; obtaining strokes and stroke sequences from the stroke sequences according to the determined Chinese characters, wherein the stroke sequences comprise the Chinese characters, the strokes corresponding to the Chinese characters and the stroke sequences corresponding to the Chinese characters; and displaying the Chinese characters in the Chinese character display area according to the stroke sequence of the Chinese characters. The device can demonstrate the correct strokes of the Chinese characters, disassemble and display all the strokes of the Chinese characters to be written, and recombine the Chinese characters by the user according to the writing plan of the strokes.

However, the above-mentioned device only enables the user to learn the correct stroke, but cannot record the writing time well, because it takes 5 seconds and 5 minutes to write a Chinese character correctly, and the mastering proficiency of the reaction is completely different, which is not beneficial for the teacher to judge the mastering proficiency of the student.
