Louis Braille, who became blind at the age of three, invented the Braille system after being inspired by a military code called "night writing" used by soldiers. His system was designed with simplicity and efficiency in mind, consisting of six dots arranged in a 3x2 grid to represent letters, numbers, and even musical notation.
Today, Braille is used in various applications, such as books, signs, and educational materials, enabling blind people to enjoy literature, access information, and communicate more effectively. The system has also been adapted for use in computing, with Braille displays allowing people to read digital content. Efforts continue to improve accessibility and make the world more inclusive for people with visual impairments.
