Thus, we base our study in a perspective that conceives language as multimodal as proposed by Kendon (1982), McNeill (2000), Cavalcante (2009), Ávila-Nóbrega; Cavalcante (2012), Fonte (2009, 2011a, 2011b, 2011c, 2012) and Fonte et al (2014) comprehending that gesture and speech are an integrated system of meaning. Based on this perspective, our general aim is to analyze the multimodal resources used by a blind child in the recount of fairy tales and as our specific aims to verify the roles of such multimodal resources that the blind child makes use of in retelling the tales, and also to identify and describe the speech, prosody and gestures during the narration of the tales. For this, we carried out an observational, qualitative and case of study research, with a nine-year-old blind child, who is blind from birth but does not present pathologies associated to his/her blindness. The child goes to Centro de Apoio pedagógico à Pessoa Visual (CAP) and also to school, where he/she is at the first year of fundamental 1. For our methodology we chose three classic tales from Disney: Little Red Riding Hood, The three Little Pigs and Snow White. These three classic tales were presented to the child in audio description in the child s home. The narration and recount of the tales were recorded and transcribed with the software Eudico Linguistic Annotator (ELAN). Besides this, we selected as categories of analysis the elements in the multimodal envelope: verbal, prosodic and gestural proposed by Ávila-Nóbrega (2010) and Fonte (2011). Results show that while recounting the tales the blind child took over different roles, sometimes the narrator, sometimes the character. These narratives were mediated by the multimodality of language, characterized by prosodic variations such as: strong and weak intensity, duration, pauses, speech speed. Furthermore, the child used verbal productions, that is, the speech, contemplating not only the narrative structure but also varied gestures including body gesticulations characterized by head movements, shoulders, hands and legs that contributed to the construction of meaning in the recount of the tales. / Esta pesquisa apresenta como objeto de estudo a multimodalidade em narrativas de uma criança cega, contribuindo para entender que recursos multimodais são utilizados por essa criança para produzir sentidos em narrativas de histórias infantis, já que ela não dispõe do canal visual para representar e perceber alguns gestos. Desse modo, fundamentamo-nos na perspectiva de funcionamento multimodal da linguagem proposta por Kendon (1982), McNeill(2000), Cavalcante (2009), Ávila Nóbrega;Cavalcante (2012), Fonte (2009, 2011a, 2011b, 2011c,2012) e Fonte et al (2014) que concebem gesto e fala como sistema integrado de significação. Com base nessa perspectiva, temos como objetivo geral analisar os recursos multimodais em narrativas de reconto de histórias de uma criança cega e como objetivos específicos verificar os papéis dos recursos multimodais que a criança cega utiliza no reconto de histórias, identificar e descrever a fala, a prosódia e os gestos durante a narração das histórias. Para isso, realizamos um estudo observacional, de caráter qualitativo e do tipo estudo de caso, no qual participou uma criança cega com 9 anos de idade, que apresenta cegueira desde nascença e não possui patologias associadas a deficiência visual. Frequenta o Centro de Apoio pedagógico à Pessoa Visual (CAP) e a escola regular, cursando o 1º ano do fundamental I. Como procedimentos metodológicos, selecionamos três clássicos infantis da Disney: Chapeuzinho vermelho, Os três porquinhos e Branca de Neve. Esses contos clássicos foram apresentados em audiodescrição para a criança cega em seu ambiente domiciliar. As narrativas dos recontos das histórias foram filmadas e transcritas através do software Eudico Linguistic Annotator (ELAN). Além disso, selecionamos como categorias de análise de dados os planos do envelope multimodal: verbal, prosódico e gestual, proposto por Ávila Nóbrega (2010) e Fonte (2011). Os resultados mostraram que, ao recontar as histórias, a criança cega assumia diferentes papéis, ora de narrador, ora de personagem. Essas narrativas foram mediadas pela multimodalidade da linguagem, caracterizada por variações prosódicas como: intensidade forte e fraca, duração, pausas, velocidade de fala; além disso, usou produções verbais, ou seja, a fala propriamente dita, contemplando a estrutura narrativa e ainda gestos variados incluindo gesticulações corporais caracterizadas pelos movimentos da cabeça, ombros, mãos e pernas que contribuíram para a construção de sentido dos recontos das histórias.

Research subjects were two students with visual impairment in different school years and age group attending multifunctional resource room (SRM) of the State Padre Nunes and Municipal Student William Tavares de Oliveira schools. Points out - that the number of target research students, although small, is full of students with visual disabilities attended in 2014 by multi-functional resources existing in the official school system of the municipality of Coxim - MS (municipality pole of the northern region DM). In addition to students, the research subjects were also the teachers of the respective multi-functional resources they attend and the teachers who attended the in mainstream education. To achieve the goal, it was launched hand of a qualitative research approach, which initially was referred to the theoretical framework that discusses the topic and was later carried out the field study procedure by means of collecting instruments such as analysis documents, observations and interviews. The results found that the two educational institutions surveyed are still building their pedagogical practice regarding the use and appropriation of information and communication technologies when used in multifunctional resource room as assistive technology. And this path is marked by questions, doubts and concerns, bringing new challenges and changing perspectives in understanding the processes of teaching and learning, mediated by the use of communication and information technologies specifically to assistive technology, despite these doubts and uncertainties it contributed more significantly the teaching and learning of students with visual impairment process. However it is of fundamental importance to teacher training for the appropriation of information and communication technologies especially in relation to work with assistive technology in educational environments so that it develops skills and abilities that allow building pedagogical practices in congruence with these technologies. / A presente pesquisa vinculada ao programa de Mestrado em Educação da UNOESTE - Universidade do Oeste Paulista teve como objetivo investigar a contribuição trazida pelo uso das tecnologias de informação e comunicação aplicadas como tecnologia assistiva na construção do conhecimento dos alunos com deficiência visual que frequentaram a sala de recursos multifuncionais. Foram sujeitos da pesquisa dois estudantes com deficiência visual de diferentes anos escolares e faixa-etária que frequentam a sala de recursos multifuncionais (SRM) das escolas Estadual Padre Nunes e Municipal Estudante William Tavares de Oliveira. Ressalta - se que o número de alunos alvo da pesquisa, apesar de pequeno, representa o total dos estudantes com deficiência visual atendidos em 2.014 pelas salas de recursos multifuncionais existentes na rede oficial de ensino do município de Coxim - MS (município polo da região norte de MS). Além dos estudantes, também foram sujeitos da pesquisa as professoras das respectivas salas de recursos multifuncionais que estes frequentam e os professores que os atenderam no ensino regular. Para alcançar o objetivo, foi lançado mão de uma abordagem de pesquisa qualitativa, na qual inicialmente, foi consultado o referencial teórico que discorre sobre a temática e, posteriormente foi realizado o procedimento de estudo de campo por meio de instrumentos de coleta, como análise de documentos, observações e entrevistas. Os resultados constataram que as duas instituições de ensino pesquisadas ainda estão construindo seu fazer pedagógico em relação ao uso e apropriação das tecnologias de informação e comunicação quando utilizadas na sala de recurso multifuncional como tecnologia assistiva. E que este caminho é pautado por dúvidas, incertezas e inquietações, trazendo novos desafios e perspectivas de mudança na compreensão dos processos de ensinar e aprender, mediados pelo uso das tecnologias de comunicação e informação especificamente à tecnologia assistiva. Apesar dessas dúvidas e incertezas, ela contribuiu de maneira expressiva no processo de ensino e aprendizagem dos alunos com deficiência visual, no entanto, é de fundamental importância a formação docente para a apropriação das tecnologias de informação e comunicação principalmente em relação ao trabalho com a tecnologia assistiva nos ambientes educacionais para que este desenvolva competências e habilidades que permitam construir práticas pedagógicas em congruência com estas tecnologias.

Orientador: Alexandre César Rodrigues da Silva / Resumo: Transmissão de dados sem fio tem se tornado cada vez mais presente no dia a dia, devido a comodidade da não utilização de cabos, bem como pela maior mobilidade propiciada. Este trabalho aborda duas tecnologias de comunicação sem fio atuais: Identificação por Radiofrequência (RFID) e Bluetooth, destacando suas principais características e apresenta o protótipo de um circuito que efetua a leitura de tags fixadas em objetos, por meio de um leitor RFID e, posteriormente, transmite a identificação dessas a um smartphone, por meio da tecnologia Bluetooth. Com o propósito de ilustrar aplicações do protótipo construído, foram desenvolvidos dois softwares para smartphones Android: um de controle de medicamento de idosos e outro para auxiliar deficientes visuais nas aulas práticas laboratoriais. Durante o desenvolvimento do trabalho, testes foram realizados para se verificar o alcance de leitura do leitor RFID utilizado. Também foram realizados testes com a tecnologia Bluetooth, verificando-se a distância máxima de conexão e transmissão/recepção de dados entre o protótipo desenvolvido e um smartphone. / Abstract: Wireless data transmission has become increasingly present in everyday life, because the convenience of not using cables, as well as the greater mobility afforded. This paper addresses two current wireless communication technologies: Radio Frequency Identification (RFID) and Bluetooth, highlighting its main characteristics and presents the prototype of a circuit that performs the reading tags attached to objects by means of an RFID reader and later transmits the identification to such a smartphone, using Bluetooth technology. In order to illustrate prototype built applications, they developed two software for Android smartphones: one for the elderly medicine control and another to assist the visually impaired in the laboratory classes. During the development work, tests were conducted to verify the read range of the RFID reader used. Also with Bluetooth technology tests were performed, checking the maximum distance connection and transmission/reception of data between the developed prototype and a smartphone. / Mestre

De nos jours, la détection et la mesure de la distance avec les ondes électromagnétiques (Radar) sont utilisées dans de nombreux domaines tels que l’aéronautique, l’automobile ou bien la médecine. Dans cette thèse, nous nous intéressons plus particulièrement au Radar dans le domaine du bien-être pour le grand public : capteur sans contact pour le suivi du sommeil, et lunettes ou canne pour malvoyants pour la détection des obstacles sur la route. Le problème posé dans cette thèse est d’ajouter les fonctionnalités nécessaires suivantes à la solution Radar existante afin de répondre à ces applications : la mesure du rythme respiratoire issu du déplacement de la cage thoracique et de l'abdomen de quelques millimètres pendant la respiration et la mesure de la direction d'arrivée de l'onde électromagnétique rétro-diffusée des obstacles devant le malvoyant. Le contexte technologique de départ est celui de la technologie ultra large bande qui offre une résolution de l’ordre du centimètre pour la mesure de distance à une portée de quelques mètres et la discrimination des signaux rétro-diffusés des multiples obstacles. Suivant les besoins, les travaux décrits ici se sont concentrés sur le canal de propagation en rétro-diffusion sur corps humain. Ils se sont aussi portés sur les techniques de traitement du signal pour pouvoir estimer le rythme respiratoire dans le signal rétro-diffusé du corps humain, et sur l'estimation de la direction d'arrivée de l'onde à un réseau d'antennes avec une résolution au degré près. Enfin, cette thèse aborde l’architecture du système, et notamment du récepteur associé au réseau d'antennes, afin de pouvoir réaliser la mesure angulaire sans augmenter la complexité, le coût et la consommation du récepteur. / Detection and ranging with electromagnetic waves (Radar) are used in a number of domains such as aeronautics, automobile or even medecin. In this thesis, we are interested particularly on Radar in the wellness domain for widely use: sleep pattern tracking sensors, smart glasses or white cane with obstacles detection for visually impaired people. The problem, which so far has not been discussed, is to add necessary functionalities as follow to the exciting solution to resolve theses applications: the thoracic and abdominal displacement tracking with a millimetric resolution; and the measurements of arrival direction of backscattered signals from obstacles in front of visually impaired individuals. The technological starting point is the one of Ultra Wideband (UWB) technology, which offers a resolution of approximate one centimeter in the distance measurement within the range of few meters and in the discrimination of backscattered signals from multiple obstacles. To meet these criterias, the research focuses on the backscattering propagation channel in particularly from the human body. It also analyses the techniques in signal processing, aiming to estimate the breathing rate in the backscattered signal of human body, and to estimate the arrival direction to an antenna array to nearly one degree. Finally, it investigates the systematic architecture, especially in the receiver associated with the antenna array, in order to withstand the angular measurement without notably increasing the receiver complexity and consumption.

The researcher found little information in literature reviewed about how Gestalt Play Therapy is being used in the treatment of visually impaired children. The aim of the study was to expand knowledge regarding this issue. A basic qualitative research study of an exploratory and descriptive nature was undertaken to describe how this therapy may be used in the treatment of such children. A representative sample was drawn from the population, consisting of gestalt play therapists who previously provided assistance to these children, using a purposive non-probability method. Data collection took place through the execution of semi-structured telephone interviews. Collected data was analysed using the Thematic Content Analysis to search for related themes (in line with the objectives of the study) in transcribed interviews. The general conclusion drawn from the empirical data was that gestalt play therapy can be used to good effect in the treatment of visually impaired children. / Die navorser het gevind dat daar weinig inligting in die literatuur beskikbaar is oor hoe gestaltspelterapie in die hulpverlening aan visueel gestremde kinders benut kan word. Die doel van die navorsingstudie was dus om kennis uit te brei rakende die benutting van gestaltspelterapie in die hulpverlening aan visueel gestremde kinders. 'n Basiese kwalitatiewe navorsingstudie met 'n verkennende en beskrywende aard is onderneem om te beskryf hoe gestaltspelterapie benut word met betrekking tot visueel gestremde kinders. 'n Verteenwoordigende steekproef is getrek, volgens 'n doelgerigte nie-waarskynlikheidsmetode, vanuit die populasie bestaande uit gestaltspelterapeute wat al van tevore hulp aan visueel gestremde kinders verleen het. Data-insameling het plaasgevind deur middel van semi-gestruktureerde telefoniese onderhoude. Die versamelde data is volgens die Tematiese Inhoudsanalise ontleed deur verbandhoudende temas (ooreenkomstig die doel van die studie) in getranskribeerde onderhoude te soek. Die algemene gevolgtrekking wat vanuit die empiriese bevindinge gemaak kan word, is dat gestaltspelterapie wel in die hulpverlening aan visueel gestremde kinders benut kan word. / Social Work / M.Diac.

Understanding fashion and dress is frequently dictated by the sense of sight and the social fact of visibility. This thesis aims to explore the phenomenon of non-visual fashion and dress with a particular focus on visually impaired people and their bodies as a site of knowledge production. While previous studies of the relationship between body and dress have examined how the sighted body is fashioned, the present small-scale and socio-sensorial study attempts to fathom how fashion and dress become perceivable in haptic, audial, and olfactory terms. This thesis engages thoughtfully with the visually impaired and their feelings related to the present-day field of fashion and dress, building on a Bourdieusan framework of habitus and embodiment applied to fashion studies. Employing qualitative interviews conducted among visually impaired women in Finland, this thesis gives voice to the people meagrely represented in the literature on fashion and dress. Furthermore, while acknowledging the empirically grounded non-visual dimension, this thesis adheres to previous contributions of revaluing the plurality of epistemologies and discourses vis-à-vis fashion, dress, and the body.

The subject of this thesis entitled What does an invisible city look like is the perception of a city and the way it is represented. The work is based on urban semiotics that sees urban environment as a particular system of communication. The methods of sensory urbanism and rhythm analysis are employed as well. The author asks whether the cities could be represented by other than visual symbols as it is usually the case for the products of tourism industry (guidebooks, souvenirs, etc.). Usually, the symbol of a particular city is formed by the image of its skyline. In Prague, this is the skyline of the Prague Castle, in Paris, it is the Eiffel tower, in New York, it is the Statue of Liberty, etc. But every city has definitely many other qualities. What are they? To find the answer, the author asks for help the visually impaired people. These people can tell easily what are the non-visual qualities of the urban space as they experience them necessarily in their everyday life and use them for better orientation. The author interviewed the visually impaired people and she also observed the way they read the city in real. The practical part of the thesis focuses on the Prague city centre.
