The term 'Braille Component' can be broken down into two parts: 'DOT' and 'Braille'. DOT is a 3 letter word that refers to the raised dots used in the Braille writing system. Braille is a tactile writing system used by people who are visually impaired, allowing them to read and write through touch. The Braille Component is the combination of the two, which is used to create a tactile representation of written language.
