Title: a four-point braille
Inventor: SEO JEONG UNG
IPC: G09B21/00
Filed: 2020-04-06
Abstract: While 6-point braille currently in use does not fully express Korean language even with 64 dots, so it is written repeatedly, 4-point braille of the present invention can display all Korean characters perfectly with 10 dots and 2 dots. The content of promises should be written down for the visually impaired who have to memorize and use punctuation marks and the promises should be predictable, systematic, and concise. According to the present invention, four-point braille is mostly made up of one or two dots, and based on 19 consonants and 6 vowels, 1, 2, 3, 4 and 6, 7, 8, 9 can be easily memorized by imagining the shape of the lower egg of an abacus in e, i, a, and u. Although 30 promises are repeated three times from 0 to 9, it is a promise that can be guessed as a promise that changes depending on the position of consonants, vowels, and final consonants. The promises may be memorized in an hour. The 6-point braille has inconveniences of not using abbreviations not using consonants as a final consonant to memorize the final consonants in addition to 64 dot patterns. In comparison with detecting 6 dots, reading and printing detecting 4 dots has a reduction effect of 40% or more, not 33%. Reducing the difficulty not only saves time and materials, but also increases detection accuracy. Since Hangul can be represtened with only 12 dot patterns, it is possible to predict the era of a convex braille device such as a date stamp in a post office as well as a small typewriter.
