The main interfaces for interaction with computers today are; keyboard, mouse and remote control. In order to interact with the presentation software Power Point, the presenter has to focus either on the computer or the buttons on the remote control. By doing this, the presenter often loses the contact with his audience and his or her flow of speech gets interrupted. This project has researched the possibility of using gestures for interaction with Power Point, by using an appliance that detects gestures. The purpose was that the interaction should be possible to realise by software, which we have done an introductory design of. We have focused on assisting presenters when they use Power Point and other applications when delivering presentation. To collect data and get an understanding of presenters, presentations and gestures we have observed presenters in action, done workshops together with future users and tested some gestures in real life. These are methods inspired from approaches such as ethnographic fieldwork and participatory design. During the whole project we have used video recording to collect and save data. To create an understanding and clear picture of what the future software should include UML-diagrams were used. We have separated gestures in two categories; natural and designed. The natural gestures occur naturally during speech and social interaction, while the designed gestures are gestures that you learn to use and express, often to perform a task. We discovered that it was the designed gestures that are best suited for gestural interaction with computer. Since the designed gestures are close to the natural way of gesturing we see them as easier to learn, remember and also more comfortable to use. We think the designed gestures have the potential to become second nature, therefore they are good to use for interaction with computers. Our research work led us to realise a need for an on/off function, to distinguish the designed gestures from the natural ones. By using a gestural interface during a presentation, the presenters can keep the focus on the audience and the message they want to convey. When gestural interfaces become reality they will introduce a paradigm shift in the way that people interact with computers and information. / Anette Eriksson 0457-12196 Caroline Svensson 0410-24148

Syftet med föreliggande studie var att göra jämförelser mellan små barn med typisk språklig utveckling och små barn med språkstörning avseende impressivt och expressivt ordförråd samt användning av gester. Fyra barn med typisk språkutveckling rekryterades till studien. Dessa barn var köns- och åldersmatchade med redan insamlat material från fyra barn med språkstörning. Åldrarna på barnen (en flicka, tre pojkar) var 33–51 månader. Impressivt och expressivt ordförråd testades med Picture Naming Game (PiNG) och testsituationen videofilmades för att möjliggöra undersökning av barnens användning av deiktiska, ikoniska och emblematiska gester. Resultaten visar att barnen med typisk språklig utveckling på gruppnivå erhöll ett högre resultat på PiNG jämfört med de matchade barnen med språkstörning. Barnen med typisk utveckling utförde ett lägre antal totalt använda gester, ett lägre antal deiktiska och ikoniska gester samt hade färre gester synkroniserade med tal jämfört med barnen med språkstörning. Barnen med typisk språklig utveckling utförde fler emblematiska gester samt hade en högre andel gester synkroniserade med tal än barnen med språkstörning. Endast en av de uppmätta skillnaderna uppnådde statistisk signifikans vilket identifierades i användandet av emblem under expressiva testuppgifter där TD-gruppen använde signifikant fler emblem än barnen i DLD-gruppen. Då inga signifikanta skillnader förelåg mellan gruppernas totala PiNG-resultat och användning av gester gjordes en gemensam korrelationsanalys där en stark och signifikant negativ korrelation (p=0,01832) mellan barnens ålder och användning av ikoniska gester identifierades. Resultatet i föreliggande studie indikerar att gestanvändningen kan vara värdefull att inkludera vid bedömning av barn och utredning av eventuell språkstörning. Det finns dock behov av fler studier inom detta område och analys av en större mängd data behövs. / The purpose of the present study was to make comparisons between young children with typical language development and young children with developmental language disorder regarding impressive and expressive vocabulary and use of gestures. Four children with typical language development were recruited to the study. These children were sex- and age-matched with already collected data from four children with language impairment. The ages of the children (one girl, three boys) were 33- 51 months. Receptive and expressive vocabulary was tested with the Picture Naming Game (PiNG) and the test situation was video recorded to enable examination of the children's use of deictic, iconic and emblematic gestures. The results show that the children with typical language development at the group level obtained a higher result on the PiNG compared to the age- and gender matched children with a developmental language disorder. The children with typical development performed a lower number of total gestures, a lower number of deictic and iconic gestures as well as fewer gestures synchronized with speech in comparison to the children with developmental language disorder. The children with typical language development performed more emblematic gestures and had a higher percentage of gestures synchronized with speech than the children with language disorder. Only one significant difference was identified between the groups. Statistical significance was identified in the use of emblematic gestures during expressive tasks of PiNG where the children in the TD-group used significantly more emblematic gestures than the children in the DLD-group. As there were no significant differences between the groups regarding the total result of PiNG and the use of gestures, a joint correlation analysis was performed where a strong and significant negative correlation (p=0.01832) between the children's age and the use of iconic gestures was identified. The results of the present study indicate that the use of gestures can be valuable to include when assessing children and investigating possible language disorders. However, there is a need for more studies in this area and analysis of a larger amount of data is needed.

Justified the decision to investigate the didactic gestures due to the fact that these units can reveal the objects to be taught and take a didactic perspective, moreover, teaching gestures can be interpreters of how the teacher's work is done and how they can reveal in response to student´s learnings about the object of study. In addition, the didactic gestures can bring light to the teaching-learning process with a genre, focusing on the development of the object decomposition process to be taught in the course of activities of the strategies, teaching tools put to use by the teacher, and all these strategies could prove the real teacher's work. We also assume that the didactic gestures allow not only identify the acting teacher (MACHADO and BRONCKART, 2009), but also the embodiment of this act establishing interaction in the construction of knowledge of the student in the classroom. We recognize the act teaching as an occupation that consists on complex gestures that if described and understood, may give the profession a character, admittedly, more professional. We use also the notions about the review model Interactionism Sociodiscursivo (BRONCKART, [1999] 2007), acting teacher (MACHADO and BRONCKART, 2009), and didactic gestures (AEBY-DAGHÉ and DOLZ, 2008). The corpus of research was audio recordings and later three classes transcripts, two classes recorded on different days within a month, with graduate students, and a recorded class with graduate students, about five months after the first recordings, totaling approximately 4 hours of recordings. The participants are students of evening courses in São Paulo, two rooms of new students in a course of Directors, with an average of 70 students per class, graduation, and 09 students in the postgraduate course in a night Educational Psychology. Analyses of data from the transcripts were based on the ISD model of analysis in respect of two categories: the production context and the overall plan of the thematic content. Based on these categories, we find the didactic gestures that lead to understanding of the teacher's work and acting teacher with regard to the object of study. The methodological approach used was the qualitative approach (ANDRÉ, 1995), described in a case study strategy (ANDRÉ, 1995) focusing on the difficulties students have in academic writing of a specific academic genre. The results showed that the specific didactic gestures reveal the teachable dimensions of an object of study and the teaching-learning process, which can create learning gestures / Esta pesquisa, inserida na área de Linguística Aplicada, tem por objetivo investigar os gestos didáticos (AEBY-DAGHÉ e DOLZ, 2008, SCHNEUWLY e DOLZ, 2009) utilizados pelo professor no ensino-aprendizagem do gênero textual resenha acadêmica, no contexto universitário e verificar como criam gestos de aprendizagem no aluno. Justifica-se a decisão por investigar os gestos didáticos devido à constatação de que estes podem revelar unidades dos objetos a serem ensinados e assumirem uma perspectiva didática. Além disso, os gestos didáticos podem ser intérpretes do trabalho do professor, podendo revelar, em resposta, a aprendizagem dos alunos sobre o objeto de estudo. Os gestos didáticos podem trazer luzes ao processo de ensino-aprendizagem de um gênero, com foco no desenvolvimento do processo de decomposição do objeto a ser ensinado no decorrer das atividades, das estratégias utilizadas e das ferramentas didáticas colocadas em uso pelo professor. Assumimos também que os gestos didáticos permitem, não só identificar o agir docente (MACHADO e BRONCKART, 2009), mas, também, o modo de realização desse agir que estabelece interação na construção do conhecimento do aluno em sala de aula. Reconhecemos o agir docente como uma atividade profissional constituída por gestos complexos que, se descritos e compreendidos, podem atribuir à profissão um caráter, reconhecidamente, mais profissional. Recorremos também às noções sobre o modelo de análise textual do Interacionismo Sociodiscursivo (BRONCKART, [1999] 2007), agir docente (MACHADO e BRONCKART, 2009), e gestos didáticos (AEBY-DAGHÉ e DOLZ, 2008). O corpus da pesquisa contou com gravações em áudio e, posteriormente, transcrições de três aulas, sendo duas aulas gravadas em dias diferentes, dentro de um mesmo mês, com alunos da graduação, e uma aula gravada com alunas da pós-graduação, cerca de cinco meses após as primeiras gravações, totalizando, aproximadamente, 4 horas de gravações. Os participantes da pesquisa são alunos de cursos noturnos da cidade de São Paulo, sendo duas salas de alunos ingressantes em um curso de Administração, com média de 70 alunos por sala, na graduação, e 09 alunas na pós-graduação de um curso noturno em Psicopedagogia. As análises dos dados obtidos nas transcrições basearam-se no modelo de análise do ISD em relação a duas categorias: o contexto de produção e o plano global dos conteúdos temáticos. Com base nessas categorias, verificamos os gestos didáticos que levam a compreensão do trabalho do professor e do agir docente no que diz respeito ao objeto de estudo. A abordagem metodológica utilizada foi a abordagem qualitativa (ANDRÉ, 1995), descritas em uma estratégia de estudo de caso (ANDRÉ, 1995) com enfoque nas dificuldades que os universitários apresentam na escrita acadêmica de um gênero textual acadêmico específico. Os resultados demonstraram que os gestos didáticos específicos revelam as dimensões ensináveis de um objeto de estudo e, no processo de ensino-aprendizagem, podem criar gestos de aprendizagem

This master thesis deals with the use of gestures in user interfaces. The goal of this thesis is to create library for hand tracking and gesture recognition in real time. For hand tracking was choosen algorithm Flock of Features. Classification of gestures is done by using algorithm DTW. This thesis also contains stage design, design and implementation of a system that uses this library. Within the tests was tested control of various application using this library.

This thesis contains descriptions of works I have made over the last two years. These descriptions have been applied to support themes of melancholia, restraint, and indeterminacy, which serve as prevalent strains connecting recent work. A few stories are also shared in the way pieces come about through thinking and making.

This thesis tests a newly developed model based on the Natyashastra, an Indian treatise on performing arts, and uses this for theatrical analysis in the contexts of British Asian theatre productions and contemporary Indian theatre in English. The study offers a tool that can provide an alternative model of analysis. By extending the existing analytical models, we can ask questions concerning the actors’ emotional manifestation and their mental state while acting. This thesis attempts to interpret the actors’ gestures and provides a structure to analyse them. In order to do that, this project uses the Natyashastra and rasa/bhava concepts as performance analysis tools, which might provide an alternate perspective to theatre analysis. The thesis reviews existing models of theatrical analysis and argues for an alternative model in Chapter One. It examines the analysis of theatre productions by scholars of British Asian theatre and contemporary Indian theatre in English in Chapter Two. Here, I review the ways in which scholars of British South Asian theatre have examined theatrical productions so far. Chapter Three tests the proposed model on four theatre productions, illustrating the ways in which theatre productions could be analysed, and identifies the model’s limitations and advantages. Chapter Four discusses findings in the light of the results analysed in Chapter Three; it also outlines some questions which needs further investigation. By doing so, this thesis contributes to the field of performance analysis and theatre studies by developing strong links between the manifestation of the actors’ bodymind, the directors' reception after their first reading of a play’s text, and playwrights’ initial emotions within the text, through production analysis.

I denna kvalitativa studie är syftet att undersöka förskollärares argument och erfarenheter till varför de använder TAKK, Tecken som Alternativ och Kompletterande Kommunikation till det yngsta barnet i förskolan, 1–3 åringar. Syftet besvarades genoms frågorna: vilka skäl har förskollärare för att använda TAKK? Vad har förskollärare för erfarenheter av användandet med TAKK? TAKK är ett verktyg som utförs med händerna och förstärker det viktigaste ordet i en mening samtidigt som personen talar och tecknar det förstärkande ordet. TAKK används av barnet och den vuxna för att hitta ett gemensamt språk som alla på förskolan kan förstå.   För att få fram resultatet till studien användes semistrukturerade intervjuer. De genomfördes med åtta förskollärare i fyra kommuner, deras tankar ställs mot det sociokulturella perspektivet. Resultatet visar att förskollärarna är positiva till användandet och menar att det är barnets rättighet att kunna få en ”röst” för att kunna påverka sin livssituation. Genom att ge barnet kommunikationsmöjligheter via TAKK ökar delaktigheten, inflytandet, självständigheten och det bidrar positivt till språkutvecklingen för barnet. Det framkom att det vardagliga användandet av TAKK i förskolan kan ses som en utmaning. TAKK ska ses som en naturlig del under hela dagen på förskolan. Engagerade förskollärare kan genom TAKK skapa stora möjligheter för barnets kommunikation, självkänsla och frihet.

The purpose of this study is to examine how body language, specifically handgestures, correlate to in-group and out-group notions. To approach the issue thehand gestures of two politicians are compared with a focus on how theirgestures relate to in-group and out-group notions in their speech. Interactionanalysis is applied, and the gestures of each politician are categorised andsummarised to be analysed. The analysis reveals that there is a distinctdifference between the two politicians in what gestures they use over all, andconsequently also differences in their gestures when discussing in-groups versusout-groups. However, the main takeaway from the discussion is that one of thepoliticians is directing their gestures towards the camera, whereas the otherpolitician mostly directs their gestures at the live audience.

Este trabalho apresenta um estudo na área de mesas interativas e uso de gestos como forma de entrada. Primeiramente é analisado um conjunto representativo de métodos de elicitação existentes que geram um vocabulário de gestos para aplicações de superfícies multitoque, como mesas interativas. Algumas das características analisadas são: custos, clareza de informações e se avalia o vocabulário final criado. São obtidos, assim, os pontos positivos e negativos dos métodos. Em seguida, as informações obtidas na análise feita, juntamente com outras informações e definições na área, permitiram a criação de um metamétodo. Esse metamétodo pode ser utilizado como base para criação de métodos, pois define desde a escolha de quais usuários utilizar nos testes até o desenvolvimento da aplicação utilizando o vocabulário de gestos criado. / This work details a study in the area of interactive tables and the use of gestures as input. First, a representative set of elicitation methods that create a vocabulary of gestures for multitouch surface application, such as interactive tables, are analyzed. Some of the characteristics analyzed are: costs, clarity of informations and whether the final vocabulary of gestures is evaluated afterwards. This way the pros and cons of the methods are established. The insights obtained in the analysis, along with other information and definitions on the area, allowed the creation of a metamethod. This metamethod can be used as a basis for creating other methods, since it defines all the steps required, from the selection of users for the test to the development of the application that will use the vocabulary of gestures created.

O objetivo desta tese é descrever a temporalização em língua de sinais brasileira (libras), no âmbito da teoria semiótica de linha francesa. Para tanto, a proposta é analisar seis textos narrativos sinalizados por surdos ou intérpretes fluentes na língua. Os estudos sobre as línguas de sinais, como os de Liddell (2003), de Finau (2004), de Johnston & Schembri (2007), de Sinte (2013), têm apontado que as línguas sinalizadas contam com os mecanismos gerais de enunciação; que não há marcas morfológicas de flexãode tempoem seus verbos, e que há outros elementosgramaticais e discursivos envolvidos na construção das relações temporais no interior de seus textos, como gestos manuais (os itens lexicaisdicionarizadosque têm função de advérbio, como HOJE, ONTEM, AMANHÃ, etc.), e como outros gestosnão manuais,como movimentos do tronco, localização das mãos e direção do olhar do sinalizador. Esta tese vai tratar de mostrar a especificidade da organização do tempo no plano do conteúdo dos textos em libras. O estudo parte das pesquisas mencionadas e toma como base para a análise o trabalho realizado por Fiorin (2002) no português, para apresentar uma descrição dos mecanismos de instauração e organização do sistema temporal de cada um dos textos selecionados, mostrando como foram marcados o MR (momento de referência) e os diferentes momentos que compõem essas histórias. A proposta foi levantar todas as formas como a libras expressa o presente, o passado e o futuro em seus discursos, descrevendo, assim, o que Greimas & Courtés (2012) denominam como sendo a localização temporal em um texto e os efeitos de sentido da instauração do tempo. Os dados analisados foram transcritos no software ELAN (EUDICO Language Annotator), seguindo a proposta de McCleary, Viotti & Leite (2010). As análises feitas mostram que, em alguns textos do corpus, a marcação do tempo é feita por itens lexicais de tempo dicionarizados, por meio de debreagens enunciativas e enuncivas, e, em outros casos, quando não há uma marca temporal específica, a língua conta com outro mecanismo discursivo, uma embreagem heterocategórica, que permite que, por meio de uma neutralização das categorias da enunciação (pessoa, espaço, tempo), o tempo seja construído espacialmente e entendido a partir de elementos que tipicamente instauram pessoa e criam diferentes espaços nos textos. / The objective of this thesis is to describe the timing in Brazilian sign language Libras within the framework of French Semiotics. As such, the proposal is to analyze six narrative texts signaled by deaf people or fluent interpreters of the language. Studies of sign languages, such as those of Liddell (2003), Finau (2004), Johnston & Schembri (2007), and Sinte (2013), have pointed out that sign languages use the general mechanisms of enunciation, that there are no morphological markers of tense inflection of verbs in these languages, and that there are other grammatical and discursive elements involved in the construction of temporal relationships within signed texts, such as hand gestures (lexical items listed in dictionaries as adverbs, such as TODAY, YESTERDAY, TOMORROW, etc.) and other non-manual gestures, such as upper-body movements, hand positions, and the direction of the signers gaze. This thesis intends to demonstrate the specificity of the organization of time in the content of the texts in Libras. The present study takes the aforementioned studies as a starting point and uses the work of Fiorin (2002) about Portuguese Language as a basis for the analysis to present a description of the mechanisms for establishing and organizing the temporal system of each of the texts selected, showing how the MR (moment of reference) and the different moments that make up these stories were marked. The proposal was to survey all the forms by which Libras expresses the present, past and future in its discourses, thus describing what Greimas & Courtés (2012) call the temporal localization in a text and the effects of meaning in terms of establishing time. The analyzed data were transcribed in the ELAN (EUDICO Language Annotator)software following the proposal of McCleary, Viotti & Leite (2010). The analyses performed showed that in some texts of the corpus the marking of time is effected by dictionarized temporal lexical items, by means of enunciative and enuncive débrayages (shifting out), and, in other cases where there is no specific temporal marker, the language uses another discursive mechanismheterocategorical embrayage (shifting in)which uses a neutralization of enunciation categories (person, space, time) to allow time to be constructed spatially and understood based on elements that typically establish the person and create different spaces in the texts.
