AI Technical Summary

Problems solved by technology

The strength and habit of primary school students or kindergarten students when learning to write are very important for the development of primary school students' writing habits in the future, but it is difficult for people to see the strength of children's pen when they learn to write through traditional writing pens. After the child finishes writing, use the marks left on the paper to determine the strength of the child's pen. This method is not accurate enough to judge, and it cannot be corrected in time when the child is writing.

In addition, when people use a pencil for sketching, it is also difficult to determine the strength of the pen
