Which of the following statements is not correct for the Braille system?
A. Transcription method for preparing Braille includes slates and stylus.
B. Character represents a letter, a combination of letters, a common word or a grammatical sign.
C. Each character in Braille system need to be recognised
D. For some languages, Braille is read from right to left

Answer 1

Braille is a generally recognised writing system used by and for blind people that consists of a code of 63 characters, each made up of one to six raised dots organised in a six-position matrix or cell. Braille characters are embossed in lines on paper and are read by delicately sliding the fingers over the manuscript.

Complete Step By Step Answer:
Cells, regardless of the language used to encode them, are read from left to right.
Each Braille character is composed of six dots arranged in a dot matrix.
Braille is created by hand or by computer.
Braille is used to transcribe natural language text by encoding individual letters, abbreviations, and shorthand contractions for each language.
Regardless of language, Braille is always read from left to right.
Hence, the correct option is: (D) For some languages, Braille is read from right to left.

Note:
Braille has been expanded to an 8-dot code, which is especially useful for use with braille embossers and refreshable braille displays. The additional dots of 8-dot braille are added at the bottom of the cell, resulting in a matrix 4 dots high by 2 dots wide. The numbers 7 (for the lower-left dot) and 8 are assigned to the additional dots (for the lower-right dot). The case of an individual letter is directly coded in the cell containing the letter in eight-dot braille, and all printable ASCII characters can be reproduced in a single cell. The Unicode standard encodes all $256\left( {{2^8}} \right)$ potential combinations of 8 dots. Braille with six dots is commonly stored as ASCII Braille.
