Tactile Signing
Tactile signing is a common means of communication used by people with deafblindness. It is based on a sign language or another system of manual communication. "Tactile signing" refers to the mode or medium, i.e. signing (using some form of signed language or code), using ''touch''. It does not indicate whether the signer is using a tactile form of a natural language (e.g. American Sign Language), a modified form of such a visual sign language, a modified form of a manually coded language, or something else. Kinds Until the 1970s, most people who were deaf and blind lived lives of isolation. As professionals became aware of this population, attempts were made to serve deafblind people by creating manual alphabets or modifying sign languages used by deaf-sighted people. See for example Helen Keller National Center, LightHouse for the Blind and Visually Impaired and Alabama Institute for the Deaf and Blind. Several methods of deafblind communication have been developed, inclu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Deafblindness
Deafblindness is the condition of little or no useful hearing and little or no useful sight. Different degrees of vision loss and auditory loss occur within each individual. Because of this inherent diversity, each deafblind individual's needs regarding lifestyle, communication, education, and work need to be addressed based on their degree of dual-modality deprivation, to improve their ability to live independently. In 1994, an estimated 35,000–40,000 United States residents were medically deafblind. Laura Bridgman was the first American deafblind person known to become well educated. Helen Keller was a well-known example of an educated deafblind individual. To further her lifelong mission to help the deafblind community to expand its horizons and gain opportunities, the Helen Keller National Center for Deaf-Blind Youths and Adults (also called the Helen Keller National Center or HKNC), with a residential training program in Sands Point, New York, was established in 1967 by ...

ASL Alphabet
The American Manual Alphabet (AMA) is a manual alphabet that augments the vocabulary of American Sign Language. Letters and digits The letters and digits are signed as follows. In informal contexts, the handshapes are not made as distinctly as they are in formal contexts. File:LSQ 1.jpg, 1 File:LSQ 2.jpg, 2 File:LSQ 3.jpg, 3 File:LSQ 4.jpg, 4 File:LSQ 5.jpg, 5 File:LSQ 6.jpg, 6 File:LSQ 7.jpg, 7 File:LSQ 8.jpg, 8 File:LSQ 9.jpg, 9 File:LSQ 10.jpg, 10 The manual alphabet can be used on either hand, normally the signer's dominant hand – that is, the right hand for right-handers, the left hand for left-handers. Most frequently, the manual alphabet is signed just below the dominant shoulder of the signer. When used within other signs or in a context in which this is not plausible, this general rule can be disregarded. J and Z involve motion. J is I with a twist of the wrist, so that the little finger traces the curve of the printed form of the letter; Z is an index finger move ...

Bay Islands Sign Language
Bay Islands Sign Language, also known as French Harbour Sign Language, is an indigenous village sign language of Honduras. It started in the village of French Harbour on the island of Roatán and spread to the neighbouring island of Guanaja. There is a high incidence of Usher syndrome Usher syndrome, also known as Hallgren syndrome, Usher–Hallgren syndrome, retinitis pigmentosa–dysacusis syndrome or dystrophia retinae dysacusis syndrome, is a rare genetic disorder caused by a mutation in any one of at least 11 genes result ... in French Harbour, which causes deafness and then blindness as well later in life. Because of this, BISL has developed both visual and tactile modes.

Nicaraguan Sign Language
Nicaraguan Sign Language (ISN; ) is a form of sign language developed by deaf children in several schools in Nicaragua. History Before the 1970s, a deaf community largely socializing with and amongst each other was not present in Nicaragua. Deaf people were generally isolated from one another and mostly used simple home sign systems and gesture () to communicate with their families and friends, though there were several cases of idioglossia among deaf siblings. The conditions necessary for a language to arise occurred in 1977 when a center for special education established a scheme that was initially attended by 50 deaf children. The number of pupils at the school (in the Managua neighborhood of San Judas) then grew to 100 by 1979, the beginning of the Sandinista Revolution. In 1980 a vocational school for deaf adolescents was opened in the Villa Libertad area of Managua. By 1983 more than 400 deaf pupils were enrolled in the two schools. Initially, the language scheme emphasized ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Sign Languages
There are perhaps three hundred sign languages in use around the world today. The number is not known with any confidence; new sign languages emerge frequently through creolization and '' de novo'' (and occasionally through language planning). In some countries, such as Sri Lanka and Tanzania, each school for the deaf may have a separate language, known only to its students and sometimes denied by the school; on the other hand, countries may share sign languages, although sometimes under different names (Croatian and Serbian, Indian and Pakistani). Deaf sign languages also arise outside educational institutions, especially in village communities with high levels of congenital deafness, but there are significant sign languages developed for the hearing as well, such as the speech-taboo languages used by some Aboriginal Australian peoples. Scholars are doing field surveys to identify the world's sign languages. The following list is grouped into three sections : * Deaf sign language ...

Deaf Education
Deaf education is the education of students with any degree of hearing loss or deafness. This may involve, but does not always, individually-planned, systematically-monitored teaching methods, adaptive materials, accessible settings, and other interventions designed to help students achieve a higher level of self-sufficiency and success in the school and community than they would achieve with a typical classroom education. There are different language modalities used in educational setting where students get varied communication methods. A number of countries focus on training teachers to teach deaf students with a variety of approaches and have organizations to support and advocate for deaf students. Identifying deaf students Children may be identified as candidates for deaf education from their audiogram or medical history. Hearing loss is generally described as slight, mild, moderate, severe, or profound, depending upon how well a person can hear the intensities of frequenc ...

Japanese Language
is the principal language of the Japonic languages, Japonic language family spoken by the Japanese people. It has around 123 million speakers, primarily in Japan, the only country where it is the national language, and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language. There have been many Classification of the Japonic languages, attempts to group the Japonic languages with other families such as Ainu languages, Ainu, Austronesian languages, Austronesian, Koreanic languages, Koreanic, and the now discredited Altaic languages, Altaic, but none of these proposals have gained any widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), extensive waves of Sino-Ja ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are and [b], pronounced with the lips; and [d], pronounced with the front of the tongue; and [g], pronounced with the back of the tongue; , pronounced throughout the vocal tract; , [v], , and [z] pronounced by forcing air through a narrow channel (fricatives); and and , which have air flowing through the nose (nasal consonant, nasals). Most consonants are Pulmonic consonant, pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of Ejective consonant, ejectives, Implosive consonant, implosives, and Click consonant, clicks. Contrasting with consonants are vowels. Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet, Linguis ...

Vowel
A vowel is a speech sound pronounced without any stricture in the vocal tract, forming the nucleus of a syllable. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in Vowel length, quantity (length). They are usually voice (phonetics), voiced and are closely involved in Prosody (linguistics), prosodic variation such as tone (linguistics), tone, intonation (linguistics), intonation and Stress (linguistics), stress. The word ''vowel'' comes from the Latin word , meaning "vocal" (i.e. relating to the voice). In English, the word ''vowel'' is commonly used to refer both to vowel sounds and to the written symbols that represent them (, , , , , and sometimes and ). Definition There are two complementary definitions of vowel, one Phonetics, phonetic and the other Phonology, phonological. *In the phonetic definition, a vowel is a sound, such as the English language, English "ah" or "oh" , produ ...

Braille Cell
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 ...

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 ...
