The present invention relates to a graphic recognition method of teaching materials using dot pattern recognition technology. The graphic recognition method of the teaching material using the dot pattern recognition technology according to the present invention is printed on the graphic area of the teaching material in a specific pattern that is difficult to identify with the naked eye, and the identification is made by the optical recognition pen according to the contact of the optical recognition pen. A method of displaying and recognizing a graphic by outputting a voice or music corresponding to the graphic by recognizing a pattern, wherein the unit graphic area of the teaching material includes a content part and a header part, and the content part is divided into a plurality of virtual sections. At least one dot pattern having content related information is formed in each section, and the header part includes one or two sections having the same size as each unit section of the plurality of virtual sections of the content part. The dog or two sections contain information about the data frame structure and orientation. A framing dot pattern is formed, and the framing dot pattern is composed of two closest dot patterns in the entire frame structure including the content portion and the header portion, and the two closest dot patterns use a framing dot pattern search algorithm. Find it.
