  Abstract

In this paper, a reverse Korean/English braille translation algorithm is developed to solve the information gap of the visually impaired, improving the smart device accessibility and convenience. This algorithm converts braille characters into keycode, and output Korean and English, numbers or punctuation marks to the smart device. In order to recognize the received input braille on the smart device, keycode conversion was used to work on Android, iOS, Windows, and MAC operating system. In addition, Korean consonants, vowels, abbreviations, English alphabets, numbers, punctuation marks, etc. have been implemented in accordance with reverse Korean braille translation regulations, making it easier for the visually impaired to use them.
