English Answer The following.

A sign language is a language that uses body language to convey meaning through movements of the hand, arms, or body, and facial expressions to express the speaker’s thoughts.
Finger spelling is the process of spelling out words by using signs using fingers that correspond to the letter of the word.
Braille is a form of written language for the blind, in which characters are represented by patterns of raised dots that are felt with the fingertips.

Braille is a system of raised dots that can be read with the fingers by people who are blind or who have very low vision. It is a kind of code language. Each alphabet is arranged by one to six raised dots known as I cell’. A single cell can be used to represent an alphabet letter, number, punctuation mark, even a whole word.

The people who are blind or have a partial loss of vision carry a long white cane which signifies that they are self-reliant and independent. ‘Honouring the white cane’ means respecting the people who are blind or visually impaired and ensuring that they don’t face any difficulty in their day to day life. We should extend a helping hand to them and help them overcome the challenges they face in life and thus ‘Honour the white cane’.
