The present invention relates to a lecture system and a method using the lecture terminal.

In general, lectures are conducted when a lecturer writes a lecture on a textbook on a blackboard, and a lecturer writes the contents written on the blackboard in a textbook or a notebook that the lecturer has.

However, when a student takes a slow writing speed compared to a lecturer's lecture, a student may not be able to correctly write the desired contents.

The electronic blackboard developed to solve this problem is composed of a white blackboard on the front to record text, an electronic circuit on the back to read images, and a printer. Print The copyboard is a wide strip of electronic paper that is rolled up and printed. Electronic blackboards reflect fluorescent light onto a white blackboard, which reflects light from an image, which is then converted into an electrical signal by a sensor. The copyboard printer uses many thermal printers using a thermal head. There is also an electrophotographic printing method on ordinary paper. Also, if you remember the blackboard image in the electronic circuit, you can continue printing any number of pages.

As such, the electronic blackboard can immediately print the written contents on the spot, so there is no need to take notes in the notebook, thereby saving time.

However, the lecturer receives the printed matter including the contents of the lecture printed through the electronic board, and the student checks the printed matter and rewrites it in his own textbook or notebook, or the printed matter is adhered to the textbook or notebook. If you need a separate operation is a cumbersome problem.

Korean Patent Publication No. 10-386842 proposes a writing content providing system using an electronic blackboard to solve this problem.

In the writing content providing system, if the content written by the user is recognized from a copyboard capable of text recognition and converted into digital data, the server stores the converted digital data from the copyboard and stores the converted digital data online or offline. It is providing the writing to the client.

However, since the conventional writing content providing system merely provides the writing content, the textbook and the writing content are not related at all, and thus, the user has to search the writing content corresponding to the teaching material. In addition, the conventional writing content providing system is provided to a plurality of clients over the Internet, and regardless of the time zone, the client has to search for and download the writing content. In addition, the conventional writing content providing system has a disadvantage in that the writing contents can be downloaded from the server only after the client accesses the server through the Internet and undergoes a complicated process such as user authentication or payment.
