World Braille Day was celebrated on January 4, 2017. Braille is a tactile writing system used by people who are visually impaired people. It is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed a code for the French alphabet which was the first version of Braille. These characters have rectangular blocks called cells that have tiny bumps called raised dots. The number and arrangement of these dots distinguish one character from another. The sets of character designations vary from language to language. There may also be embossed illustrations and graphs that appear in braille text.
With the use of screen reader software, braille usage has declined. However, because it teaches spelling and punctuation, braille education remains important for developing reading skills among blind and visually impaired children. USD 475 recently upgraded its websites to include ALT text or alternative text for all images so that screen readers can read the text instead of the image for visually impaired individuals.
