How Do Blind People Read And Write ?

Introduction 
Blind people read and write through Braille script. Braille script is a system of writing that uses raised dots to enable the blind people to read and write through sense of touch. The system consists of 63 characters, each having one to six raised dots arranged in six position matrix or cell embossed in lines of paper. Blind people move their fingers lightly over the copy to read the text. Louis Braille invented the system in 1824 when he was a student at the National Institute for Blind Children, Paris.
