Braille alphabet

Braille is a tactile writing system using patterns of raised dots arranged in cells of up to six dots (two columns of three). Each combination represents a letter, numeral, or punctuation, enabling visually impaired individuals to read through touch. For example, the letter "A" is a single raised dot in the top left position, while "B" has dots in the top left and middle left. This systematic arrangement allows users to recognize characters by feeling the pattern of dots with their fingertips, providing access to written language across multiple languages and contexts.
