Normally, Braille devices are too expensive for regular users, which often face illiteracy due to lack of access to printers, and machines to read text. Out of 285 million visually impaired people on the planet, only five percent can read. One percent of books are translated to Braille and reading devices cost above $2,000.

teacher. All this under $300.
