Haptický model kláštera Obětování Panny Marie / Haptic model of the Church and the Monastery of Oblation to the Blessed Virgin Mary in Ceske Budejovice

JELÍNEK, Lukáš January 2018 (has links)
This thesis called Haptic Model of the Monastery of Presentation of the Blessed Virgin Mary is composed of two parts, theoretical and practical one. The theoretical part is dealing with selected period of Christian monastery complexes history. There are also mentioned some of the significant events of Christian world, that indisputably have influenced developement of monastic structures. Later on there is described the historical developement of the Monastery of Presentation of the Blessed Virgin Mary in České Budějovice (Budweis). The last chapter focuses on issues of people with visual impairment. The practical part of this thesis is based on creating of haptic model of the Monastery of Presentation of the Blessed Virgin Mary in České Budějovice in approximate measuring scale 1:125, which is supposed to be used primarily by visually impaired as a haptic-tactile aid, so that they can create an ideal image of shape of the monastery complex.

Analyse du couplage personne-système haptique / Study of Human-Haptic System Dynamic Coupling

Herrera Gamba, Diana 04 July 2012 (has links)
Les travaux décrits dans ce document abordent le problème du couplage dynamique homme-système haptique. Nous proposons une étude de ce couplage basée sur l'hypothèse d'un système hybride temporaire. Selon cette hypothèse, le système formé lors du couplage peut être considéré comme un système dynamique dont les deux parties ne peuvent pas être séparées. Ce sujet est pluridisciplinaire, se situant à l'intersection des sciences cognitives, de l'automatique et de l'haptique. La première partie du document comporte un état de l'art sur l'analyse du couplage dans ces trois domaines, une description de la problématique et de la méthode à utiliser pour notre étude ainsi qu'une proposition des typologies du geste. Lors de cette étude du couplage, nous nous intéressons à un groupe de gestes particuliers, notamment le geste périodique et le geste passif dans une situation de simulation haptique ainsi qu'aux modèles d'interaction capables de les générer. La méthode générale, consiste à définir des approches pour la modélisation du couplage main-système haptique pour ensuite réaliser une analyse du système couplé à partir d'une acquisition des données du système lors du couplage et en utilisant des méthodes d'identification de paramètres issus de l'automatique pour caractériser les modèles. La dernière partie, décrit la mise en place du dispositif pour l'analyse expérimentale du couplage en situation de simulation avec une interaction haptique. Ce dispositif permet l'acquisition des données du geste pour l'analyse. Nous présentons également, l'étude réalisée sur le simulateur haptique afin d'établir l'équivalence entre les paramètres virtuels introduits et issus du simulateur et des paramètres physiques réels. Ensuite, nous décrivons l'analyse expérimentale des différentes situations de couplage proposées. Les expériences effectuées lors de cette étude ont été réalisées sur la plateforme temps réel ERGON_X, conçue par l'ACROE/ICA. Les résultats de ces expériences ont permis de quantifier les modèles du geste et d'observer ses composantes, selon les modèles établis. Mots clés : haptique, interface haptique, interfaces homme-machine, simulation temps réel, couplage homme-objet, geste, modélisation physique, identification de paramètres. / The work described in this document deals with the problem of human-haptic system dynamic coupling. We propose a study of this kind of coupling based on the hypothesis of a temporary hybrid system. Under this hypothesis, the system formed during the coupling can be considered as a dynamic system in which the two parties that compose it cannot be separated. This is multidisciplinary topic, situated at the intersection of cognitive science, automation and haptics. The first part of the document includes a state of the art on the analysis of coupling in these three areas, the description of the problem and the methodology for the study as well as a proposal of gesture typology. In this study of coupling, we are interested in a particular group of actions, such as periodic movement and passive gesture in a situation of haptic simulation and also, in the interaction models able to generate them. The general method is to define the approaches for modeling the hand-haptic device coupling and then perform an analysis of the coupled system by acquiring system data during the coupling and using parameter identification methods to characterize the models. The final section describes the implementation of the device for the experimental analysis of coupling during simulation with a haptic interaction. This device allows data acquisition for gesture analysis. We also present the study of the haptic simulator to establish the equivalence between virtual parameters introduced to and returned by the simulator and real physical parameters. Then, we describe the experimental analysis of different proposed coupling situations. The experiments performed for this study were performed using the real-time platform ERGON_X, designed by ACROE / ICA. The results of these experiments were used to quantify gesture models and to observe its components, according to established models. Keywords: haptic, haptic interface, human-machine interfaces, real-time simulation, human-object coupling, gesture, physical modeling, parameter identification.

Thus, studies that evaluate the coded memory through active manipulation of objects, the haptic memory, are scarce, in particular the assessment of long-term oblivion rates. In the healthy aging process subsystems memory have different significant decline in its components. Therefore, the present study aimed to evaluate the real objects oblivion rates and family processed in the haptic and visual modality in two time slots to recall memories and recognition in a sample of 104 elderly people, of both sexes, without commitment cognitive. For this, a wooden box and a turntable for the presentation of haptic and visual stimuli, respectively were used. The procedure consisted of two phases, one phase of study (stimulus presentation) and another test (recall or recognition tasks), at intervals of 1 hour or 1 day. The Mann-Whitney test for independent samples showed significant differences in the recall task only at 1 day interval, with a superior visual recall of information (U = 55.50, p = 0.029, r =-0,60). In the assessment of the accuracy of recognition revealed that only 1 day interval was no significant difference, however, by superior to haptic condition (U = 55.50, p = 0.029, r =-0,55). In summary, the results show that for different memory tasks evaluation condition influences the forgetting rates over time. So it is necessary that new designs, with the addition of more extended periods of time, may bring further clarification. / As classificações utilizadas para os estudos da memória podem variar em relação a natureza da codificação dos estímulos, quanto ao tempo em que as informações permanecem armazenadas para posterior evocação e quanto a forma de aprendizado envolvida. Dessa forma, os estudos que avaliam a memória codificada através manipulação ativa dos objetos, a memória háptica, são escassos, em especial a avaliação das taxas de esquecimento a longo prazo. No processo de envelhecimento saudável os subsistemas da memória apresentam declínio significativo diferenciado em seus componentes. Diante disso, a presente pesquisa teve por objetivo avaliar as taxas de esquecimento de objetos reais e familiares processadas na modalidade háptica e visual em dois intervalos de tempo para memórias de recordação e reconhecimento em uma amostra de 104 idosos, de ambos os sexos, sem comprometimento cognitivo. Para isso, foi utilizada uma caixa de madeira e uma plataforma giratória para a apresentação dos estímulos hápticos e visuais, respectivamente. O procedimento consistiu em duas fases, uma fase de estudo (apresentação dos estímulos) e outra de teste (tarefas de recordação ou reconhecimento), realizada após os intervalos de 1 hora ou 1 dia. Foram encontradas diferenças significativas na tarefa de recordação apenas no intervalo de 1 dia, com uma superioridade na recordação visual das informações (U=55,50, p=0,029, r=-0,60). E na avaliação da acurácia do reconhecimento revelou que apenas no intervalo de 1 dia houve diferenças significativas, no entanto, com superioridade para a condição háptica (U=55,50, p=0,029, r=-0,55). Em resumo, os resultados mostram que para as diferentes tarefas de avaliação da memória a condição influencia nas taxas de esquecimento ao longo do tempo. Assim é necessário que novos delineamentos, com o acréscimo de intervalos de tempo mais prolongados, possam trazem maiores esclarecimentos.

No. of bitstreams: 1 parte1.pdf: 2157506 bytes, checksum: f860bc902af866c32087958813a3a8b9 (MD5) Previous issue date: 2011-03-23 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Associate to Virtual Reality, the incorporation of haptic systems makes possible to extend the level of realism and provide a more efficient way of involvement, bringing better results in performing the activities of tactile nature embedded in applications and games. However, there are few incentives for implementing these devices in serious games. The development of serious games in immersive environments and the inclusion of non-conventional devices such as haptic devices, may contribute to the motivation and learning of the player. This work has as main objective the design, study, research, development and discussion of the incorporation of haptic systems in serious games, specifically in Odontology related to adult s oral hygiene. Though, the serious games development needs a multidisciplinary team. Thus, this work also proposes and tests a serious game development process which aims to achieve a good set of approach, content and technology for a correct planning and specification of the game. / Aliado à Realidade Virtual, a incorporação de sistemas hápticos possibilita ampliar o nível de realismo e oferecer uma forma mais eficiente de envolvimento, trazendo melhores resultados na realização das atividades de natureza tátil inseridas em aplicações e jogos. Entretanto, poucos são os incentivos da aplicação destes dispositivos em serious games. O desenvolvimento dos serious games em ambientes imersivos e a inclusão de dispositivos não convencionais, como dispositivos hápticos, podem contribuir para a motivação e aprendizado do jogador. Desta forma, este trabalho traz como principal objetivo a concepção, estudo, investigação, desenvolvimento e discussão da aplicação de sistemas hápticos em serious games, mais especificamente na construção de um jogo para a área Odontológica relacionada à higiene bucal de adultos, podendo este, ser utilizado para propiciar o entendimento melhor dos conceitos, como também, na fixação de técnicas de escovação e procedimentos envolvidos. Entretanto, o desenvolvimento de um serious game necessita de uma equipe multidisciplinar no qual profissionais da área que o conteúdo do jogo se relaciona precisa estar em constante comunicação com a equipe de design e desenvolvimento. Desta forma, também é proposto e testado neste trabalho, um modelo de processo para o desenvolvimento de serious games que visa alcançar um bom conjunto de abordagem, conteúdo e tecnologia para o correto planejamento e especificação do jogo.

Design do livro tátil ilustrado: processo de criação centrado no leitor com deficiência visual e nas técnicas de produção gráfica da imagem e do texto / Design tactile illustrated book: creation process focused the reader with visual impairment and the graphic production techniques image and text

Elizabeth Romani 28 April 2016 (has links)
Esta pesquisa aborda o design do livro tátil ilustrado, uma obra que possibilita a inclusão do leitor com deficiência visual. A investigação está centrada no modo como a mensagem é expressa no texto e na imagem, a partir do entendimento da tipografia, da diagramação, da linguagem empregada na ilustração e da produção gráfica. O objetivo da pesquisa é discutir sob a ótica do design a produção atual desta categoria de livro, entendendo-se que o livro tátil ilustrado configura-se como um objeto multissensorial que explora, principalmente, a percepção tátil, sendo esta um recurso também utilizado no despertar da curiosidade do leitor em fase de alfabetização. Para o leitor, principalmente, o cego, é importante desenvolver a sensibilidade tátil ainda na infância, por isso o livro físico como uma fonte de informação é instrumento fundamental de formação perceptiva. Grande parte da produção do livro tátil ilustrado está vinculada a conhecimentos oriundos da pedagogia, desenvolvidos nos centros de assistência à pessoa com deficiência visual, muitas vezes, sem a participação integral do designer no projeto. Por esta razão, no Brasil, os livros oriundos de diferentes iniciativas assemelham- se e são caracterizados pela produção tradicional, seguindo a concepção de material didático para cegos. Recentemente, uma nova concepção de livros multissensoriais para crianças tem sido elaborada por um número restrito de editoras, fundamentalmente as europeias, que exploram diferentes técnicas de acabamento na obtenção da imagem tátil. Esta pesquisa parte da hipótese que grande parte das imagens presentes nos livros táteis ilustrados produzidos no Brasil não são interpretadas pelo cego. São apresentados os desdobramentos desta questão relacionados ao entendimento da imagem e do texto. Entre eles, indaga-se: a linguagem dos desenhos táteis estaria condizente com o leitor cego? A técnica de obtenção do relevo interfere no processo de leitura? O texto auxilia no entendimento da imagem? A composição rígida das páginas favorece a leitura? A ausência de estudos específicos sobre o livro tátil ilustrado no campo do design e as restritas publicações bibliográficas no âmbito da leitura háptica conduziram para o levantamento de campo: visita às escolas especializadas, visita aos museus acessíveis e leitura mediada junto ao público de interesse. Além disso, realiza-se a análise de seis obras com diferentes concepções de ilustrações táteis, sendo três nacionais: O Chapeuzinho vermelho, de Bia Villela, Abraço de urso, de Cláudia Cotes, Adélia sonhadora, de Lia Zatz; e três importadas: Ruvidino in piscina, do Istituto dei Ciechi di Milano, Des vers de travers, de Anette Diesen, e Petit souffle de vent, de Elisa Lodolo. As leituras têm o propósito de discutir a compreensão da imagem, do texto e a composição do livro. Esses livros são analisados a partir de referências do design gráfico e da percepção visual, com maior ênfase nas obras de Bruno Munari e Rudolf Arnhein. Por fim, produz-se uma série de trabalhos práticos de caráter experimental a partir de narrativas que suscitam ampliar a discussão do processo de projetar um livro tátil ilustrado. Os resultados mostram que grande parte das imagens táteis presentes nas publicações brasileiras não são compreendidas pelos leitores cegos, sendo que um conjunto de fatores associados corrobora para este resultado, entre eles, identifica-se a linguagem das ilustrações, a técnica de produção e ausência do concreto na relação do texto com a imagem. / This research addresses the tactile illustrated book design, a work that enables the inclusion of the reader with visual impairments. The research is centered on how the message is expressed in the text and the image, from the understanding of typography, the layout, the language used in the illustration and mass production. The aim of the research is to discuss from the viewpoint of design the current production of this book category, on the understanding that the illustrated tactile book figure as a multi-sensory object that explores mainly the tactile perception, this being a feature also used to arouse the reader\'s curiosity in the literacy phase.For the reader, especially the blind, it is important to develop a tactile sensitivity in its childhood, therefore the physical book as a source of information is a fundamental tool of perceptual training. A great part of the production of illustrated tactile book is tied to knowledge originating from pedagogy, developed at the assistance centre for visually impaired and very often without the full involvement of the designer in the project. For this reason, in Brazil, books from different initiatives are similar and are characterized by traditional production, in accordance with didactic material for the blind. Recently, a new concept of multi-sensory books for children have been developed by a limited number of publishers, primarily European, exploring different finishing techniques in obtaining the tactile image. This research starts from the assumption that most of the images presented in the illustrated tactile books produced in Brazil are not interpreted by the blind. Will be presented the developments on this issue related to the understanding of image and text. Amongst them: the language of tactile drawings would be consonant with that of the blind reader? The embossing technique interferes in the reading process? The text assists in the understanding of the image? The rigid composition of the pages stimulate the reading? The absence of specific studies regarding the tactile illustrated book in the field of design and the strict bibliographic publications within the haptic reading led to the field survey: visits to specialized schools, visits to acessible museums and reading mediated by the target public. In addition, the analysis of six books, each one with different conceptions of tactile illustrations, was carried out, being three of them national: O Chapeuzinho vermelho, by Bia Villela, Abraço de urso, by Cláudia Cotes, Adélia sonhadora, by Lia Zatz; and three from abroad: Ruvidino in piscina, by Istituto dei Ciechi di Milano, Des vers de travers, by Anette Diesen and Petit souffle de vent, by Elisa Lodolo. The readings are meant to discuss the understanding of image, text and the book\'s composition. These books are analyzed based on references brought from graphic design and visual perception, with greater emphasis on the works of Bruno Munari and Rudolf Arnhein. Finally, it was produced a series of practical work of an experiential nature from narratives which intend to broaden the discussion about the process of designing a tactile illustrated book. The results demonstrated that the majority of tactile images present at Brazilian publications are not understood by blind readers - a set of associated factors corroborates to this result: the illustration language, the reproduction technique and absence of concrete in the relation between text and image.

Application for Customisable Interaction with Physical Objects : A Tool for Speech and Language Therapists

Herault, Romain Christian January 2015 (has links)
Physical objects with digital properties are being used more and more by the public. One such term for these artefacts include "the Internet of Things''. Most of these objects are often impossible to further modify or customise, and thus serve just the single purpose intended by their creators. This thesis explores the possibility of customising physical objects in order to provide an affordable and flexible way of interacting with them. A prototype, involving a mobile phone application (Android) and wireless sensor technology (NFC tags), was developed for the medical domain of speech and language therapy. The system, developed in close association with two therapists, allows the customisation of current speech and language exercise and associated material. It is designed to also assist with logging the patient interactions during the conduction of such exercises. The proposed solution has been tested and validated by medical experts, and its user interface evaluated by non-patient users.

Design and control of a teleoperated palpation device for minimally invasive thoracic surgery

Buttafuoco, Angelo 25 February 2013 (has links)
Minimally invasive surgery (MIS) consists in operating through small incisions in which a camera and adapted instruments are inserted. It allows to perform many interventions with reduced trauma for the patient. One of these is the ablation of peripheral pulmonary nodules.<p><p>Nevertheless, the means for detecting nodules during MIS are limited. In fact, because of the lack of direct contact, the surgeon cannot palpate the lung to find invisible lesions, as he would do in classical open surgery. As a result, only clearly visible nodules can be treated by MIS presently.<p><p>This work aims at designing, building and controlling a teleoperated palpation instrument, in order to extend the possibilities of MIS in the thoracic field. Such an instrument is made of a master device, manipulated by an operator, and a slave device which is in contact with the patient and reproduces the task imposed by the master. Adequate control laws between these two parts allow to restore the operator's haptic sensation. The goal is not to build a marketable prototype, but to establish a proof of concept.<p><p>The palpation device has been designed in collaboration with thoracic surgeons on the basis of the study of the medical gesture. The specifications have been deduced through experiments with experiencied surgeons from the Erasmus Hospital and the Charleroi Civil Hospital.<p><p>A pantograph has been built to be used as the master of the palpation tool. The slave is made of a 2 degrees of freedom (dof) clamp, which can be actuated in compression and shear. The compression corresponds to vertical moves of the pantograph, and the shear to horizontal ones. Force sensors have been designed within this project to measure the efforts along these directions, both at the master and the slave side, in order to implement advanced force-feedback control laws and for validation purposes.<p><p>Teleoperation control laws providing a suitable kinesthetic force feedback for lung palpation have been designed and validated through simulations. These simulations have been realized using a realistic model of lung, validated by experienced surgeons. Among the implemented control schemes, the 3-Channel scheme, including a local force control loop at the master side, is the most efficient for lung palpation. Moreover, the increased efficiency of a 2 dof device with respect to a 1 dof tool has been confirmed. Indeed, a characteristic force profile due to the motion in 2 directions appeared in the compression force tracking, making the lesion easier to locate. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished

Vnímání vertikality u pacientů s vývojovou dyspraxií / Perception of verticality in patients with developmental coordination disorder

Žídek, Radim January 2017 (has links)
Bibliographic identification Author's first name and surname: Bc. Radim Žídek Title of the master thesis: Perception of verticality in patiens with developmental coordination disorder Department: Department of Rehabilitation and Sports Medicine, 2nd faculty of medicine, Charles University and FN Motol Supervisor: PhDr. Ondřej Čakrt, Ph.D. The year of presentation: 2017 Annotation: Developmental coordination disorder is typical for poor motor learning and motor coordination that cannot be related to any neurological or mental disease. The exact reason of it stays still unknown. There are theories that say that dysfunctional collaboration of afferent systems causes developmental coordination disorder. Thanks to afferent systems a human organism is able to perceive different modalities. One of the modalities is a perception of verticality. In theoretical part of this thesis we summarized information about developmental coordination disorder and postural and balance control. In experimental part we tested 35 pupils of primary school (age 13-15). Using MABC-2 we classified the pupils into children with and without predispositions for developmental coordination disorder. Then we tested their ability of perceiving subjective visual and subjective haptic verticality. According to statistical evaluation there is no...

Right Brain Study

Griffin, Velda L 01 January 1985 (has links)
The purpose of this study is to show that instructional methods designed for right-brained students will make a significant difference in the reading achievement scores of the students when compared with the scores of right-brained sixth grade students not receiving these instructional methods.The subjects were sixth grade students who use the right hemisphere of the brain to a greater degree than the left hemisphere. The subjects' cerebral preference was determined by a test known as the Cerebral Preference Index (CPI). Ten students each were chosen from two sixth grade classes. The study consisted of a Control Group and Experimental Group. During the study the Control Group received eight weeks of the regular school's program while the Experimental Group received eight weeks of instructional strategies that take hemispheric specialization into consideration. The results indicated that there was no significant difference in the reading achievement scores of those students who received the instructional methods designed for right brained students. The analysis of data did suggest that those scoring high on the pre-test scored high on the post test. The results indicated the same outcome for low scorers.
