Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of information networks, and in particular, the contents displayed on a large display board used in a group education institution such as a school, a cram school, a preparatory school, a culture center, etc. It relates to a local network system that is sent and displayed by.

[0002]

2. Description of the Related Art Conventionally, blackboards, whiteboards, etc. have been prepared in classrooms at group education institutions, and educators such as teachers and teachers use chalk or whiteboard markers on the blackboards and whiteboards to explain. I try to deepen my understanding by showing the contents to be shown in letters and figures. Then, the students and students each transcribe the contents written on these boards into the notebook while listening to the lecture.

[0003]

However, the educator writes the contents to be explained one after another on a board such as a blackboard and erases them.
Since the operation of erasing and writing is repeated, there are the following problems. If this writing or erasing operation is done quickly,
There is a problem that the students, etc. cannot transfer to the notebook. It is difficult to listen to the lecture and move the transcription at the same time.
Educational effects will be reduced. If the letters written on the board are small, or if you are seated far away from the board, or if you have nearsightedness or weak eyesight, you need to focus more on the transcription, and you cannot transfer it. There's a problem. The present invention provides a local network system that solves such a problem, reforms a conventional educational system in an educational institution, and improves the educational effect.
