Braille is a tactile writing system designed for individuals with visual impairments, enabling them to read and write through touch. Invented by Louis Braille in 1824, it uses raised dots arranged in cells of up to six dots, representing letters, numbers, punctuation, and even musical and scientific symbols. Each cell is configured uniquely to correspond to a specific character or instruction. Braille can be written using specialized tools like a slate and stylus or Braille typewriters and printers. Widely used worldwide, it plays a crucial role in promoting literacy, independence, and accessibility for blind and visually impaired individuals.
