Braille is a tactile writing system designed for individuals who are blind or visually impaired. It consists of raised dots arranged in patterns within a 2x3 grid to represent letters, numbers, and punctuation marks. Each character or symbol is formed by a specific combination of these dots. For example, the letter "A" is represented by a single dot in the upper-left position, while "B" is formed by two dots in the upper-left and middle-left positions. Developed by Louis Braille in the early 19th century, Braille allows users to read and write through touch, providing access to literature, information, and education. Its significance lies in empowering individuals with visual impairments, enhancing their ability to communicate and navigate the world independently.
