Night Writing
Night writing is the name given to a form of tactile writing invented by Charles Barbier de la Serre (1767–1841). It is one of a dozen forms of alternative writing presented in a book published in 1815: ''Essai sur divers procédés d'expéditive française, contenant douze écritures différentes, avec une planche pour chaque procédé'' (Essay on various processes of French expedition, containing twelve different writings, with a plate for each process). The term (in French: ''écriture nocturne'') does not appear in the book, but was later applied to the method shown on Plate VII of that book. This method of writing with raised dots that could be read by touch was adopted at the Institution Royale des Jeunes Aveugles (Royal Institution for Blind Youth) in Paris. A student at the school, Louis Braille, used the tools and Barbier's idea of communicating with raised dots in a form of code, and developed a more compact and flexible system for communications, Braille.

1829 Braille
Louis Braille's original publication, ''Procedure for Writing Words, Music, and Plainsong in Dots'' (1829), credits Barbier's night writing as being the basis for the braille script. It differed in a fundamental way from modern braille: It contained nine decades (series) of characters rather than the modern five, utilizing dashes as well as dots. Braille recognized, however, that the dashes were problematic, being difficult to distinguish from the dots in practice, and those characters were abandoned in the second edition of the book. The first four decades indicated the 40 letters of the alphabet (39 letters of the French alphabet, plus English ''w''); the fifth the digits; the sixth punctuation; and the seventh and part of the eighth mathematical symbols. The seventh decade was also used for musical notes. Most of the remaining characters were unassigned. Script As in modern braille, most of the higher decades were derived from the first: *Decades 1–4 were the same as tod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York Point
New York Point (New York Point: ) is a braille-like system of tactile writing for the blind invented by William Bell Wait (1839–1916), a teacher in the New York Institute for the Education of the Blind. The system used one to four pairs of points set side by side, each containing one or two dots. (Letters of one through four pairs, each with two dots, would be .) The most common letters are written with the fewest points, a strategy also employed by the competing American Braille. Capital letters were cumbersome in New York Point, each being four dots wide, and so were not generally used. Likewise, the four-dot-wide hyphen and apostrophe were generally omitted. When capitals, hyphens, or apostrophes were used, they sometimes caused legibility problems, and a separate capital sign was never agreed upon. According to Helen Keller, this caused literacy problems among blind children, and was one of the chief arguments against New York Point and in favor of one of the braill ...

Charles Barbier De La Serre
Charles Barbier de la Serre (; 18 May 1767 – 22 April 1841) was the French inventor of several forms of shorthand and alternative means of writing, one of which became the inspiration for Braille. Barbier was born in Valenciennes and served in the French artillery from 1784 to 1792. He left France during the Revolution and lived for several years in the United States, returning to France during the reign of Napoleon Bonaparte. He did not rejoin the military. Barbier was interested in shorthand and other alternative writing forms. In 1815, he published a book titled, ''Essai sur divers procédés d'expéditive française''. In this book, Barbier explains that conventional writing is a barrier to universal literacy because it takes too long to learn, and people who must earn their living (farmers, artisans) cannot devote the necessary time to education. Barbier was also concerned about the barriers to literacy faced by people with visual or hearing impairments. Raised-point wri ...

Royal Institution For Blind Youth
The Institut National des Jeunes Aveugles (''National Institute for Blind Youth'') is a special school for blind students in Paris, France. It is considered the first school for the blind in the Western world, and has served as a model for many subsequent schools for blind students. Origins At the end of the 18th century, Europeans began to take an interest in the education of the blind. Before that time, the blind were treated as if they were incapable of being educated (despite the fact that many blind people born to families with the means to provide them with individual tutoring had become well educated). In 1784, Valentin Haüy, a linguist and translator for the king, appalled at the treatment of blind people and the fact that most blind people were poor and unable to do more than beg for a living, undertook to teach a young blind man called François Lesueur to read raised letters, proving that the blind were capable of reading and writing.

Louis Braille
Louis Braille ( ; ; 4 January 1809 – 6 January 1852) was a French educator and the inventor of a reading and writing system named after him, braille, intended for use by visually impaired people. His system is used worldwide and remains virtually unchanged to this day. Braille was blinded in one eye at the age of three. This occurred as a result from an accident with a stitching awl in his father's harness making shop. Consequently, an infection set in and spread to both eyes, resulting in total blindness. At that time, there were not many resources in place for the blind, but he nevertheless excelled in his education and received a scholarship to France's Royal Institute for Blind Youth. While still a student there, he began developing a system of tactile code that could allow blind people to read and write quickly and efficiently. Inspired by a system invented by Charles Barbier, Braille's new method was more compact and lent itself to a range of uses, including music. ...

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 ...

Coordinates
In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine and standardize the Position (geometry), position of the Point (geometry), points or other geometric elements on a manifold such as Euclidean space. The coordinates are not interchangeable; they are commonly distinguished by their position in an ordered tuple, or by a label, such as in "the ''x''-coordinate". The coordinates are taken to be real numbers in elementary mathematics, but may be complex numbers or elements of a more abstract system such as a commutative ring. The use of a coordinate system allows problems in geometry to be translated into problems about numbers and ''vice versa''; this is the basis of analytic geometry. Common coordinate systems Number line The simplest example of a coordinate system is the identification of points on a line (geometry), line with real numbers using the ''number line''. In this system, an arbitrary point ''O'' (the ''ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoneme
A phoneme () is any set of similar Phone (phonetics), speech sounds that are perceptually regarded by the speakers of a language as a single basic sound—a smallest possible Phonetics, phonetic unit—that helps distinguish one word from another. All languages contain phonemes (or the spatial-gestural equivalent in sign languages), and all spoken languages include both consonant and vowel phonemes; phonemes are primarily studied under the branch of linguistics known as phonology. Examples and notation The English words ''cell'' and ''set'' have the exact same sequence of sounds, except for being different in their final consonant sounds: thus, versus in the International Phonetic Alphabet (IPA), a writing system that can be used to represent phonemes. Since and alone distinguish certain words from others, they are each examples of phonemes of the English language. Specifically they are consonant phonemes, along with , while is a vowel phoneme.

Valentin Haüy
Valentin Haüy (pronounced ; 13 November 1745 – 19 March 1822) was the founder, in 1785, of the first school for the blind, the Institute for Blind Youth in Paris (now Institut National des Jeunes Aveugles, or the ''National Institute for the Young Blind'', INJA). In 1819, Louis Braille entered this school. Life Haüy was born into a family of weavers. His father, a full-time loomer, also held the job of ringing the Angelus bells in a local Premonstratensian, Premonstrant Abbey. The abbey monks educated Valentin and he became a skilled Linguistics, linguist speaking ten different languages of the day. He also studied Ancient Greek and Biblical Hebrew, Hebrew. In 1783, he gained the title "interpreter to the king", Louis XVI. In 1786, he was the interpreter of the King, to the Admiralty and the City Hall. He was a member of the Office of Writing. Haüy's impulse to help the blind started in 1771, after he stopped for lunch in a cafe on the Place de la Concorde, Paris. There, ...

Nyctography
Nyctography (''in Nyctography:'' ) is a form of substitution cipher writing created by Lewis Carroll (Charles Lutwidge Dodgson) in 1891. It is written with a nyctograph (a device invented by Carroll) and uses a system of dots and strokes all based on a dot placed in the upper left corner. Using the Nyctograph, one could quickly jot down ideas or notes without the aid of light. Carroll invented the Nyctograph and Nyctography as he was often awakened during the night with thoughts that needed to be written down at once, and didn't want to go through the lengthy process of lighting a lamp only to have to then extinguish it. The nyctograph The device consisted of a gridded card with sixteen square holes, each a quarter inch wide, and system of symbols representing an alphabet of Carroll's design, which could then be transcribed the following day. He first named it "typhlograph" from ("blind"), but at the suggestion of one of his brother-students, this was subsequently changed int ...
