The method of reading and writing system implemented by Louis Braille for the Blind people is really good and an innovative approach taken by him. This method helps the blind persons to read the letters and numbers through touch the dots. The dots are raised in shapes of letters and digits in the paper. The Blind persons will recognize the letters and digits by touching the raised dots in the paper. The same method is also used for writing.
This methods was implemented by Louis Braille in the year 1825. He was born in 4th January, 1809. This day would be a remember-able one by the blind people to give respect to Louis Braille. He passed away on 6th January, 1952.
Suppose, this method was not implemented by Braille then the blind persons may suffer to read and write the numbers and words. There also may be a chance for having some alternate method by someone to fulfill the needs of blinds.
