A novel Braille pad with dual text-to-Braille and Braille-to-text capabilities with an integrated LCD display

Braille is the writing system that visually impaired people use to write or read or to communicate. This research paper presents a novel design of a low-cost, low-power, portable and user-friendly Braille system. The advantage of the system is that the designed system serves as both Braille writing and reading system, so visually impaired people can enhance their Braille writing and reading skills without the assistance of a Braille teacher. The designed system takes the input through Braille keyboard and produces the Braille output in Braille display; the corresponding English characters are also displayed on the LCD and also in the laptop if it is connected. It also has the capability of reading documents as text. By implementing the designed Braille system in schools and homes, Braille literacy rate can be increased and visually impaired people can be employed and can fully participate in the society.
