The designed system takes the input through Braille keyboard and produces the speech output and it also has the capability to read documents. It is believed that by implementing the designed Braille system in schools and homes, Braille literacy rate can be increased and visually impaired people can be employed and can fully participate in society. Braille printer or braille embosser (is the same thing), do the same thing as a regular printer, but it prints for blind people. Braille is named after its creator, Frenchman Louis Braille, who lost his eyesight due to a childhood accident. A full Braille cell includes six raised dots arranged in two lateral rows each having three dots. The dot positions are identified by numbers from one through six. 64 solutions are possible from using one or more dots. A single cell can be used to represent an alphabet letter, number, punctuation mark, or even an entire word. Key Words: Arduino, Braille Keyboard, Braille, Braille Code, Speech Output(Speaker). 1. INTRODUCTION According to the survey of world health organization (WHO), there are more number of visually impaired people living in various countries. Because of the rate of Braille literacy in various countries is alarming low which effect on the significant relationship between higher income and employment, braille literary and academic success and also an education plays a crucial role. Now a days a very less number of people are learning to read and write. A Braille system consists of 6 dots, in two columns where 3 dots in each column. Using this 6 raised dots 64 different sign can be created. There are three types of Braille system encoding such as Grade 1, Grade 2 and Grade 3. Where Grade 1 consists of letter-by-letter transcription it is used for basic literacy and it also consists of English standard alphabets and punctuation marks. In Grade 2 Braille system is made up of English alphabets, punctuation marks, number(0 to 9) and contractions. This system is used for books, menus and other Braille materials. It also consists of few words. Grade 3 Braille system is used for personal use. It consists of entire words shortened to a few letters. 1.1 I. NEED OF PROJECT Keyboard:- -The presented solution is low cost -It is portable to carry everywhere -It is user friendly and easy to use -It is based on text to speech concept -User would be able to here what they type Printer:- -The presented solution is handy and can be carried anywhere -It consumes very less energy -It also uses coding in C language so it is easy to interface it with the keyboard -It uses a simple A4 size paper. 1.2 I. LITERATURE SURVEY There is variety of brands devices available in the market for visually impaired people to help them in educational activities and to bridge the communication gap between visually impaired people and people with sight.
