Braille-a short note

 Braille enables blind people to read and write with a system based on touch .

 Louis Braille (1809-1852) was 15 years old when he designed a system of raised dots to signify an alphabet so that it would be easy to read by touch.

 He became blind at the age of 4 in an accident while playing in his dad's saddled workshop.

 He studied at the National Institute for blind Children (Paris). 

 In 1821, Charles Barbier a former captain visited the school , where Braille was introduced to letter code that Barbier developed to enable soldiers to communicate without sound or light at night 

 The reader has to move his finger around to recognize the sound .
