What Is the Braille System?

Braille, or braille, is embossed. It is specially designed for the blind and touches the senses. Through braille plates, braille machines, braille printers, etc., different combinations of bumps are made on the paper. Generally, the braille of each square is composed of six dots. The left side is 123 from top to bottom, and the right side is 456. Call a party. It was created by the French blind Louis Blair in 1824, so it is commonly known internationally as "Braille".

"Reading Braille", which features 12 points in each of the left, middle, and right columns, and implements the reform of the phoneme system of Chinese Braille (referring to the initials, primordials, vowels, and tones of syllables). One-to-one correspondence, the dot structure is strict, suitable for thumb reading or sliding reading. It has three advantages: easy to learn, sketch, and read.

"Reading Braille" uses one tone (12 o'clock) and one tone (phonological tone), and adopts the strategies of "reverse 90 °" and "thumb reading." Compared with the current Braille and general Braille, it is rich in national characteristics, the reading efficiency of Braille is more efficient, and the input speed of Braille is faster.

Design "Reading Braille", the purpose is: to create easy to learn and efficient Chinese Braille, sincerely serve the blind! The goal is: a map to learn to read Braille!

Paper publications with raised symbols for the blind to read with their fingers. The internationally used Braille symbol was invented in Paris by the French blind L. Braille (1809 ~ 1852) in 1824. Each Latin letter and punctuation mark occupy 6 positions (2 × 3), which is composed of 1 to 6 dots arranged at different positions. It is called the Blair character system, and is commonly called braille. Countries have developed their own Braille scripts based on their own characteristics and referring to this system. Before 1949, there were several kinds of Braille in China, but they were all Chinese phonetic notation, which was inconvenient to use. In 1952, the blind person Huang Nai, who was the chairman of the Chinese Association of the Blind, Deaf and Mute, created a new Braille based on the Braille system, based on Chinese Pinyin characters, and used words as units, which provided a better way for the publication of Braille. condition. The printing methods of Braille publications have undergone a series of evolutions. Early use of hard lead alloy type (braille), embossed on cardboard to make the dots bulge. In the future, special machines were used to print braille on tin-plated steel plates, which were used as mother boards instead of alloy movable type embossing. Both were hollow dots. In recent years, light-sensitive resins or foamed resins have been used, and the mother board perforated with braille has been used for missed printing. The ink is then cured by infrared irradiation or heated and foamed to become solid braille. The advantage of this method is that the edge of the braille is clearer than the hollow braille, which is easier to read, the book has a longer service life, and does not need to use heavy cardboard, making the book lighter. China's existing Braille Institute and printing plants, blind schools use textbooks printed in the country, and also publish a Braille monthly magazine and a variety of magazines such as art, science and technology.
