In general, when teaching at schools (elementary, middle and high schools), academies, and companies, the lectures were conducted mainly using a blackboard or a white board, and most of the lectures are still conducted in the same way at most schools and companies.

In this way, when a lecture is conducted using a blackboard or a white board, lecturers (teachers, professors, and instructors) see the blackboard or the white board. There is a problem in that the contents cannot be delivered efficiently, and when the lecture is conducted using the blackboard, chalk powder is blown, which causes harm to the health of the lecturer.

In particular, if a lecture is conducted using a blackboard and a white board, the size of the font cannot be arbitrarily adjusted unless a large font is used, and thus, the contents of the lecture cannot be delivered accurately and effectively, and the lecture is efficiently conducted for a large number of students. Not only can't be delivered or delivered, but there are limitations to the lecture.
