For over 150 years, a system of raised dots known as braille has been the fundamental system of written communication for the blind. Perkins School for the Blind reports that there exist braille codes for over 130 languages from around the world. Even beyond the classroom, braille is an indispensable tool in the daily lives of people who are blind or visually impaired. Fortunately, advances in technology have the potential to make braille more readily available than ever before.
