AbstractIn contrast with two widely held and contradictory views – that sign languages of deaf people are “just gestures,” or that sign languages are “just like spoken languages” – the view from sign linguistics and developmental research in cognition presented by Goldin-Meadow & Brentari (G-M&B) indicates a more complex picture. We propose that neuroscience research suggests that a similar approach needs to be taken and offer some examples from research on the brain bases of sign language perception.

<p>This thesis provides the first documentation and description of the signs created and used by deaf individuals in Vanuatu. The specific aims of this research were as follows: to establish the sociolinguistic context experienced by deaf people in Vanuatu; to identify the repertoire and characteristics of signs used by the deaf participants; to compare features of participants’ individual signs with the characteristics of home signs and emerging sign languages; and to consider the degree of similarity and potential similarity of signs between participants and how this reflects individuals’ opportunities for contact with other deaf people and signing interlocutors. The limitations of this study are that field methodology for data collection was developed in situ as conditions allowed. The sociolinguistic context for deaf Ni-Vanuatu confirms that language isolation leads to marginalisation from community and society. The study established that these home sign lexicons were limited in quantity and conceptual range, and that shared background knowledge was essential for comprehension. Overall, 22 handshapes were documented, and the predominant handshapes unmarked. Most participants preferred handling strategy for depicting signs. Some evidence of noun-verb distinction was noted in the repertoire of some participants. However, across this range of formational characteristics, results showed significant individual variations. Furthermore, multiple barriers have precluded development of a shared sign language and any form of deaf community.</p>

&lt;p&gt;Sign languages &amp;#8203;&amp;#8203;arise from the need of communities of deaf people to communicate with each other and with others. Like all natural languages, they are tied to the traditions and cultures of the communities that invented and developed them. The sign language used in Italy is the Italian Sign Language, LIS.&lt;/p&gt; &lt;p&gt;The strong iconicity of LIS is very interesting from the point of view of communication and didactics of astronomy, also for the hearing impaired. The signs used for astronomical concepts and objects often express the meaning and nature of what is represented, much more than a single word in the Italian language does.&lt;/p&gt; &lt;p&gt;LIS is therefore effective not only for inclusive communication aimed at deaf people, but it can be effective for everyone, both in terms of equity and awareness of diversity and in terms of knowledge of astronomy and its link with culture and tradition.&lt;/p&gt; &lt;p&gt;We will present a set of videos published on EduINAF, the outreach and education online magazine of the Italian National Isntitute for Astrophysics, in which the LIS is the main medium of the storytelling. Each video has subtitles, in order to make the LIS understandable for all.&lt;/p&gt;

Deaf people, as a marginal community, may have severe problems in communicating with hearing people. Usually, they have a lot of problems even with such—for hearing people—simple tasks as understanding the written language. However, deaf people are very skilled in using a sign language, which is their native language. A sign language is a set of signs or hand gestures. A gesture in a sign language equals a word in a written language. Similarly, a sentence in a written language equals a sequence of gestures in a sign language. In the distant past deaf people were discriminated and believed to be incapable of learning and thinking independently. Only after the year 1500 were the first attempts made to educate deaf children. An important breakthrough was the realization that hearing is not a prerequisite for understanding ideas. One of the most important early educators of the deaf and the first promoter of sign language was Charles Michel De L’Epée (1712-1789) in France. He founded the fist public school for deaf people. His teachings about sign language quickly spread all over the world. Like spoken languages, different sign languages and dialects evolved around the world. According to the National Association of the Deaf, the American Sign Language (ASL) is the third most frequently used language in the United States, after English and Spanish. ASL has more than 4,400 distinct signs. The Slovenian sign language (SSL), which is used in Slovenia and also serves as a case study sign language in this chapter, contains approximately 4,000 different gestures for common words. Signs require one or both hands for signing. Facial expressions which accompany signing are also important since they can modify the basic meaning of a hand gesture. To communicate proper nouns and obscure words, sign languages employ finger spelling. Since the majority of signing is with full words, signed conversation can proceed with the same pace as spoken conversation.

AbstractDeaf people who form part of a Deaf community communicate using a shared sign language. When meeting people from another language community, they can fall back on a flexible and highly context-dependent form of communication calledinternational sign, in which shared elements from their own sign languages and elements of shared spoken languages are combined with pantomimic elements. Together with the fact that there are few shared sign languages, this leads to a very different global language situation for deaf people as compared to the situation for spoken languages and hearing people as analyzed in de Swaan (2001). We argue that this very flexibility in communication and the resulting global communication patterns form the core of deaf culture and a key component of the characterization of deaf people as “visual people.” (Globalization, sign language, international sign, Deaf culture, language contact, multilingualism)*

Comunidad  Sorda es aquella que participa de unos valores culturales y lingüísticos construidos en torno a la lengua de signos y a una concepción visual del mundo. Entre las personas sordas usuarias de la lengua de signos algunas aprendieron a signar en su infancia y otras siendo ya adultas; hay quienes son usuarias de audífonos o implantes cocleares y, entre ellas, hay quienes usan la lengua de signos y quienes no. También debemos mencionar a aquellas personas sordas que, a causa de un sistema educativo no inclusivo, tienen problemas de expresión y comprensión de textos escritos. Al igual que en el resto de la población, entre las personas sordas encontraremos niños, jóvenes, mayores, personas sordas con otra(s) discapacidad(es)... Todas y cada una de ellas con sus necesidades y demandas concretas. Es importante saber que, aun tratándose de un colectivo heterogéneo, todas las personas sordas, cualquiera que sea su tipo o grado de sordera, situación individual e independientemente de que sean o no usuarias de las lenguas de signos, comparten la necesidad de acceder a la comunicación e información del entorno sin barreras de ningún tipo. Por ese motivo es necesario desarrollar un servicio de orientación, asesoramiento y acción tutorial específico para el alumnado sordo que tenga en cuenta sus necesidades y dificultades y que evite cualquier tipo de discriminación o falta de accesibilidad al contenido universitario del tipo que sea. Por lo tanto, es necesario proporcionar este servicio con los recursos audiovisuales necesarios, intérpretes de lengua de signos española y formación continua a la comunidad universitaria. Es fundamental coordinarse con las asociaciones de personas sordas para cumplir los requisitos básicos que garanticen su inclusión, puesto que éstas son las que conocen mejor sus necesidades por la lucha de sus derechos, y orientar a la universidad para la consecución de dicha finalidad.   A Deaf Community is one that participates in cultural and linguistic values built around sign language and a visual conception of the world. Among the deaf people who used sign language, some learned to sign in their childhood and others when they were adults; there are those who use hearing aids or cochlear implants and, among them, there are those who use sign language and those who do not. We will also find deaf people who, because of a non-inclusive educational system, have problems of expression and comprehension of written texts. As in the rest of the population, among the deaf people we will find children, young people, elderly, deaf people with other disability(ies). . . Each and every one of them with their specific needs and demands. It is important to know that, even if it is a heterogeneous collective, all deaf people, whatever their type or degree of deafness, individual situation and regardless of whether or not they are users of sign languages, share the need to access the communication and information of the environment without barriers of any kind. For this reason it is necessary to develop a service of guidance, advice and specific tutorial action for deaf students that takes into account their needs and difficulties and avoids any type of discrimination or lack of accessibility to university content of any kind. Therefore, it is necessary to provide this service with the necessary audiovisual resources, Spanish sign language interpreters and continuing education to the university community. It is essential to coordinate with associations of deaf people to meet the basic requirements to ensure their inclusion, since they are the ones who best know their needs by fighting for their rights, and guide the university to achieve that goal.

Sign Languages

Just as no one can pinpoint the origins of spoken language in prehistory, the roots of sign language remain hidden from view. What linguists do know is that sign languages have sprung up independently in many different places. Signing probably began with simple gestures, but then evolved into a true language with structured grammar. "In every place we've ever found deaf people, there's sign," says anthropological linguist Bob Johnson. But it's not the same language. "I went to a Mayan village where, out of 400 people, 13 were deaf, and they had their own Mayan Sign - I'd guess it's been maintained for thousands of years." Today at least 50 native sign languages are "spoken" worldwide, all mutually incomprehensible, from British and Israeli Sign to Chinese Sign.

There are a lot of people who have many disabilities in our world out of which,people who are deaf and dumb cannot convey there messages to the normal people. Conversation becomes very difficult for this people. Deaf people cannot understand and hear what normal people is going to convey ,similarly dumb people need to convey their message using sign languages where normal people cannot understand unless he/she knows or understands the sign language. This brings to a need of an application which can be useful for having conversation between deaf,dumb and normal people. Here we are using hand gestures of Indian sign language (ISL) which contain all the alphabets and 0-9 digit gestures. The dataset of alphabets and digits is created by us.After dataset building we extracted the features using bagof- words and image preprocessing.With the feature extraction, histograms are been generated which maps alphabets to images. Finally, these features are fed to the supervised machine learning model to predict the gesture/sign. We did also use CNN model for training the model.

Historical Trajectory

Sign languages, structurally different from oral languages, are based on gestures and involve their own grammars and repertoires of lexical units (signals or signs), and they play an important role in establishing communication among deaf people around the world. This chapter primarily focuses on the development of dictionaries for Libras (an acronym for Língua Brasileira de Sinais, or ‘Brazilian Language of Signs’), the natural language of the Brazilian deaf community. It traces the influence of the first dictionary of the deaf in Brazil, Iconographia dos Signaes dos Surdos-Mudos (‘Iconography of Signs of Deaf-Mutes’), which was published in 1875 by the National Institute of Education of the Deaf (INES) and authored by Flausino José da Gama, a student at the Institute. In their demonstration of the influence and inspiration this dictionary gave to lexicographers who followed da Gama, Bidarra and Martins outline the historical trajectory of sign languages up to the present, considering different and parallel paths for sign languages in different countries, forms of stigmatization of sign language, and barriers to its use. Incorporating this historical and transnational analysis, Bidarra and Martins present both a broad discussion of the various models of sign language dictionaries that have been used around the world and an in-depth analysis of the development of Libras dictionaries in Brazil to the modern day.

Sign languages (SL) are the first language for most deaf people. Consequently, bidirectional communication among deaf and non-deaf people has always been a challenging issue. Sign language usage has increased due to inclusion policies and general public agreement, which must then become evident in information technologies, in the many facets that comprise sign language understanding and its computational treatment. In this study, we conduct a thorough systematic mapping of translation-enabling technologies for sign languages. This mapping has considered the most recommended guidelines for systematic reviews, i.e., those pertaining software engineering, since there is a need to account for interdisciplinary areas of accessibility, human computer interaction, natural language processing, and education, all of them part of ACM (Association for Computing Machinery) computing classification system directly related to software engineering. An ongoing development of a software tool called SYMPLE (SYstematic Mapping and Parallel Loading Engine) facilitated the querying and construction of a base set of candidate studies. A great diversity of topics has been studied over the last 25 years or so, but this systematic mapping allows for comfortable visualization of predominant areas, venues, top authors, and different measures of concentration and dispersion. The systematic review clearly shows a large number of classifications and subclassifications interspersed over time. This is an area of study in which there is much interest, with a basically steady level of scientific publications over the last decade, concentrated mainly in the European continent. The publications by country, nevertheless, usually favor their local sign language.

This commentary describes our perspective on transinstitutionalization as deaf teachers and researchers from different regions of Canada, and accounts for some of the ways in which transinstitutionalization manifests in the lives of deaf people, particularly in educational settings. In the present day, so-called inclusive education is often presented as the progressive alternative to institutionalization, or deaf schools. However, mainstream education in regular settings without adequate sign language support and the continuing polarization of language and identity options for deaf children are two of the main ways in which transinstitutionalization recurs for deaf children and adults and threatens the vitality of sign languages.
