Description

System for displaying modifiers on bulletin boards, method and recording medium {SYTEM, METHOD AND STORING MEDIA FOR REPRESENTING EXPRESSION OR SYMBOL ON BBS}

The present invention relates to a system for displaying a web-based formula code using a real-time image generation technology on a bulletin board, a method thereof, and a medium for recording such a program. More specifically, a user writes and inputs a formula on a text-based bulletin board. It relates to a bulletin board operator's server system and a method of posting a modifier symbol that transmit information to the operator server so that information including a formula can be posted on a bulletin board, and a medium for recording a program for implementing such a method.

In the web-based Internet, bidirectional communication is generally performed by a bulletin board program or a guestbook program by a CGI program. Looking at the basic structure, the user calls out the posting form of the bulletin board provided by the web server through the web browser, which is the input unit, and inputs the information to be posted in the input window of the form, and the web server receives the post through the gateway engine. It is a system that the gateway engine creates a web document and posts it on the bulletin board when it is stored in the storage DB and the user requests an inquiry. In short, such bulletin board systems are limited to posting text-based information.

However, as the Internet population grows, two-way communication demands based on online increase, and the types of information to be exchanged are expanded to non-textual information, and the exchange of image information is confirmed in real time through a web browser instead of file exchange. The need is very high. In the case of an online professor, for example, a mathematics course is opened on the website, and when the lecture is given, various special symbols are required for the Q & A content. Furthermore, the integrator, which inputs variables, is also created in the bulletin board system and exchanged as images The need to do that is getting urgent. In the future, such demands will be extended to formulas and sheet music.

In this regard, the Republic of Korea Patent Publication (Publication No. 2000-6791) can be used to draw a picture or formula using a text, figure, pen, etc. in the question and answer area using the active-X control for question and answer An online question-and-answer system is released to ensure that this is possible. However, this system has a drawback in that the information to be expressed is drawn by hand using a pen mouse. In addition, www.deayu.co.kr/xmath.html introduces the formula writing system implemented by the technique called Xmath. However, since the formula is edited based on the tex or latex syntax, the program size is large and the execution speed is slowed down. It is not scalable, such as adding a new symbol.

The present invention is to solve the above problems, to provide a system that provides a bulletin board in real time on a web browser without a third server or a separate program.

Still another object of the present invention is to provide a bulletin board system that is easy to maintain and expand a function of a system displaying a modifier symbol on a bulletin board and is easy to use by a user.

Still another object of the present invention is to provide a method of posting a bulletin board by expressing a mathematical symbol in real time on a web browser.

Still another object of the present invention is to provide a medium in which a program is recorded so that the expression can be posted on a bulletin board in real time on a web browser.
