Problems solved by technology

[0002] Now there are some multimedia teaching systems that project the PPT prepared by the teacher in advance through the projector. There are the following problems in the use of the multimedia system: it will also make the teacher unable to demonstrate the hand-drawn drawings very well, which brings difficulties to the teaching process. It is very inconvenient; in some places with narrow spaces, due to the distance limitation, the projector cannot be used, which affects the normal teaching; the existing multimedia teaching systems are all fixed and cannot be moved flexibly
