Problems solved by technology

[0003] Keyboards are often used in computer technology and science teaching, but most of the keyboards used in traditional computer technology and science teaching are fixed and cannot be adjusted according to personal habits and height, especially when elementary school students or junior high school students use keyboards to learn When the teacher is operating, because the physical development of the students is not mature at this time, the elevation may be quite different from the height of the teacher, and it is extremely inconvenient to operate the keyboard at this time
