American Braille
American Braille was a popular braille alphabet used in the United States before the adoption of standardized English Braille in 1918. It was developed by Joel W. Smith, a blind piano tuning teacher at Perkins Institution for the Blind in Boston, and introduced in 1878 as ''Modified Braille''. In 1900 it was renamed ''American Braille''. Rather than ordering the letters numerically, as was done in French Braille French Braille is the original braille alphabet, and the basis of :Innovative braille scripts, almost :French-ordered braille scripts, all others.

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...

Braille
Braille ( , ) is a Tactile alphabet, tactile writing system used by blindness, blind or visually impaired people. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. For blind readers, braille is an independent writing system, rather than a code of printed orthography. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first Binary numeral system, binary form of writing developed in the modern era. Braille characters are f ...

English Alphabet
Modern English is written with a Latin-script alphabet consisting of 26 Letter (alphabet), letters, with each having both uppercase and lowercase forms. The word ''alphabet'' is a Compound (linguistics), compound of ''alpha'' and ''beta'', the names of the first two letters in the Greek alphabet. The earliest Old English writing during the 5th century used a runic alphabet known as the Anglo-Saxon futhorc, futhorc. The Old English Latin alphabet was adopted from the 7th century onward—and over the following centuries, various letters entered and fell out of use. By the 16th century, the present set of 26 letters had largely stabilised: There are 5 vowel letters and 19 consonant letters—as well as Y and W, which may function as either type. Written English has a large number of Digraph (orthography), digraphs, such as , , , , and . Diacritics are generally not used to write native English words, which is unusual among orthographies used to write the languages of Eu ...

English Braille
English Braille, also known as ''Grade 2 Braille'', is the braille alphabet used for English. It consists of around 250 letters ( phonograms), numerals, punctuation, formatting marks, contractions, and abbreviations (logograms). Some English Braille letters, such as , correspond to more than one letter in print. There are three levels of complexity in English Braille. Grade 1 is a nearly one-to-one transcription of printed English and is restricted to basic literacy. Grade 2, which is nearly universal beyond basic literacy materials, abandons one-to-one transcription in many places (such as the letter ) and adds hundreds of abbreviations and contractions. Both Grade 1 and Grade 2 have been standardized. "Grade 3" is any of various personal shorthands that are almost never found in publications. Most of this article describes the 1994 American edition of Grade 2 Braille, which is largely equivalent to British Grade 2 Braille. Some of the differences with Unified English Brai ...

Perkins School For The Blind
Perkins School for the Blind, in Watertown, Massachusetts, was founded in 1829 and is the oldest school for the blind in the United States. It has also been known as the Perkins Institution for the Blind. Perkins manufactures its own Perkins Brailler, which is used to print embossed, tactile books for the blind; and the Perkins SMART Brailler, a braille teaching tool, at the Perkins Solutions division housed within the Watertown campus's former Howe Press. History Founded in 1829, Perkins was the first school for the blind established in the United States. The school was originally named the New England Asylum for the Blind and was incorporated on March 2, 1829. The name was eventually changed to Perkins School for the Blind. John Dix Fisher first considered the idea of a school for blind children based upon his visits to Paris at the National Institute for the Blind and was inspired to create such a school in Boston, but it was founded by Samuel Gridley Howe, who had also ...

French Braille
French Braille is the original braille alphabet, and the basis of :Innovative braille scripts, almost :French-ordered braille scripts, all others. The collation, alphabetic order of French has become the basis of the international braille convention, used by most braille alphabets around the world. However, only the 25 basic letters of the French alphabet plus ''w'' have become internationalized; the additional letters are largely restricted to French Braille and the alphabets of some neighboring European countries. Letters In numerical order by decade, the letters are: For the purposes of accommodating a foreign alphabet, the letters ''ì, ä, ò'' may be added: There are also numerous contractions and abbreviations in French braille. Punctuation Punctuation is as follows: The lower values are readings within numbers (after the Antoine number marker: see below). Formatting and mode Formatting and mode-changing marks are: As in English Braille, the capital sign is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate And Stylus
The slate and stylus are tools used by blind people to write text that they can read without assistance.Alpha Chi Omega (1908) Invented by Charles Barbier as the tool for writing letters that could be read by touch, the slate and stylus allow for a quick, easy, convenient and constant method of making embossed printing for Braille character encoding. Prior methods of making raised printing for the blind required a movable type printing press. Design The basic design of the slate consists of two pieces of metal, plastic, or wood fastened together with a hinge at one side.Harry Houdini Collection (1888) The back part of the slate is solid with slight depressions spaced in braille cells of six dots each. The depressions are approximately deep and about in diameter. The horizontal and vertical spacing between dots within a cell is approximately , while the distance between adjacent cells is about . The front of the slate consists of rectangular windows that fit over the bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perkins Brailler
The Perkins Brailler is a "braille typewriter" with a key corresponding to each of the six dots of the braille code, a space key, a backspace key, and a line space key. Like a manual typewriter, it has two side knobs to advance paper through the machine and a carriage return lever above the keys. The rollers that hold and advance the paper have grooves designed to avoid crushing the raised dots the brailler creates. Although braille notation was designed for people who are blind or visually impaired to read, prior to the introduction of the Perkins Brailler, writing braille was a cumbersome process. Braille writers created braille characters with a stylus and slate (as developed by Louis Braille) or by using one of the complex, expensive, and fragile braille writing machines available at the time. History The first Braille writer machine was presented by Frank Haven Hall in 1892. The original Perkins Brailler was produced in 1951 by David Abraham (1896–1978), a woodwork ...

Helen Keller
Helen Adams Keller (June 27, 1880 – June 1, 1968) was an American author, disability rights advocate, political activist and lecturer. Born in West Tuscumbia, Alabama, she lost her sight and her hearing after a bout of illness when she was 19 months old. She then communicated primarily using home signs until the age of seven, when she met her first teacher and life-long companion Anne Sullivan. Sullivan taught Keller language, including reading and writing. After an education at both specialist and mainstream schools, Keller attended Radcliffe College of Harvard University and became the first deafblind person in the United States to earn a Bachelor of Arts degree. Keller was also a prolific author, writing 14 books and hundreds of speeches and essays on topics ranging from animals to Mahatma Gandhi. Keller campaigned for those with disabilities and for women's suffrage, labor rights, and world peace. In 1909, she joined the Socialist Party of America (SPA). She w ...
