Supporting User Engagement in Participatory Design: A Multiple-fidelity Prototyping Approach

Lau, Charlotte January 2019 (has links)
Over the history of interaction design, concepts and methods of prototyping have been significantly developed to address new challenges faced by the field and the ever-going advancement of new technologies. Some of the important developments are related to the notions of mixed-fidelity prototyping, experience prototyping, and prototypes as filters. Building upon these developments, this study explores a multiple-fidelity prototyping approach, that is, using progressively higher fidelity prototypes in iteration. The study focused particularly on the design of user engagement. It documented, and contributed to, an actual design process of Xplore, an augmented reality game-based learning application. Three participatory design-style workshops employing low-, mixed-, and high-fidelity prototypes were conducted respectively. Thematic analyses of participants’ interactions revealed sets of themes in the workshops, which reflected the changing focus and scope of the design space. The implications of the results obtained in the study highlighted the role of prototypes of each fidelity level in engaging users in a design process, as well as the potential benefits of combining multiple fidelity prototypes when designing for user engagement.

Uma análise nos principais aspectos da construção calçadista para o desenvolvimento de um solado-protótipo feito a partir de fibra de coco / An analysis in the main aspects of the footwear construction for development of a prototype soloed made from coconut fibers.

Costa, Célia Regina da 02 April 2013 (has links)
Os calçados são essenciais na vida humana, eles possuem a função primordial de proteger os pés e interagem constantemente com o indivíduo. Além do aspecto funcional, se exige qualidade, conforto e estética em sua confecção. Os fatores antropométricos e biomecânicos contribuem nessa interface ao oferecer parâmetros científicos na sua forma ergonômica. Confeccionar um calçado que garanta a saúde para os pés necessita conhecer os fatores que estão direta ou indiretamente relacionados à sua história, ao processo de produção, a matéria-prima entre outros itens relacionados ao calçado, assim com um embasamento científico pode dar um melhor suporte ao processo de desenvolvimento do produto. Neste contexto, a dissertação teve por objetivo organizar estes conceitos de maneira que forneça informações essenciais para a construção de um calçado confortável, pois há uma dificuldade em encontrar uma gama de conhecimentos reunidos sobre calçados para o desenvolvimento de novos projetos. Neste sentido, o estudo investigou também as características da fibra de coco verde, dos frutos descartados na cidade de Francisco Morato - São Paulo, para verificar a viabilidade de aplicação dessas fibras na construção de partes do calçado. Para a realização deste trabalho foi fundamentado uma revisão teórica que apontou a evolução do calçado na história da humanidade, os fatores indispensáveis para oferecer o conforto, a análise do pé humano, conhecimento sobre a matéria-prima e algumas possibilidades de agregarem a fibra natural de coco verde para a fabricação de um protótipo para solado feito da fibra coco. A metodologia utilizada refere-se aos aspectos teóricos numa abordagem de conhecimentos para a confecção calçadista e, que possam ser empregados na etapa da produção do protótipo. Foi feita uma maceração biológica nas fibras e realizados testes de tração e microscopia óptica. As fibras foram extraídas do coco, analisadas em testes laboratoriais e posteriormente agregadas a uma resina (PVAc Poliacetato de Vinila) para formar o protótipo. Os resultados mostraram que as fibras de coco verde possuem potencial em relação a outras fibras naturais estudadas em literaturas, para serem aplicadas como reforços na construção de partes do calçado. Possuem a rigidez necessária aos materiais usados na fabricação do sapato e, uma proteção natural graças à presença de lignina. Porém, há necessidade de que as informações da cadeia produtiva sejam mais acessíveis e amplas a nível científico e, possibilitem a criação de alternativas mais eficazes e na melhoria das técnicas já existentes no mercado. Há uma grande possibilidade do emprego das fibras naturais em substituição das fibras sintéticas para serem empregadas na fabricação de partes dos calçados como, por exemplo, nos solados e palmilhas. / Shoes are essential mode of human life; they have the primary function of protecting the feet and constantly interact with the individual. Besides the functional aspect, if demands quality, comfort and aesthetics in its making. The anthropometric and biomechanical factors contribute to this interface and provide scientific parameters for its ergonomic design. Manufacturing a shoe that ensures the health of the human foot aims to know the factors that are directly or indirectly related to its history, production process, raw materials and other factors related to shoes, so with a scientific background can better support the process of product development. In this context, the dissertation aimed to organize these concepts in a way that provides essential information for the construction of comfortable shoes and can influence new ideas to use in the footwear sector, since there is a difficulty in finding a range of knowledge gathered over shoes, which are important for the development of new projects. In this sense, the study also investigated the characteristics of green coconut fiber, fruit discarded in the town of Francisco Morato - São Paulo, to verify the feasibility of these fibers in the construction of parts of footwear. For this work was based showed that a theoretical evolution of footwear in the history of mankind, the factors necessary to provide comfort, a study of foot, knowledge of the raw materials and some possibilities of aggregating the natural fiber coconut for manufacturing a prototype for soles made of coconut fiber. The methodology used refers to the theoretical approach knowledge for making footwear and which may be used in the production step of the prototype. We conducted a biological maceration into the fibers and performed tensile testing and optical microscopy. The fibers were extracted from coconut analyzed in laboratory tests and then aggregated to a resin (PVAc - Vinyl polyacetate) to form the prototype. The results showed that coconut fibers have potential in relation to other natural fibers studied in literatures, for use as reinforcements in building parts of the footwear. Have the necessary rigidity to the materials used in manufacturing the shoe, and a natural protection due to the presence of lignin. However, there is need for the information of the production chain are more accessible and wide-ranging scientific level and thus allow the creation of more effective alternatives and that the techniques could be improved. There is a great possibility of using natural fibers in place from synthetic for use in footwear, for instance, in the soloed and shoe insole.

The application of visualisation techniques to the process of building performance analysis

Pilgrim, Matthew John January 2003 (has links)
Visualisation, the representation of data in visual form, is at the core of our ability to communicate information. Without clear representation, data would remain in its raw form thus greatly hindering the communication process. This is especially the case when the data source is large, complex and subject to change. One such area is related to the use of computer based simulation tools for thermal analysis. This research investigates the potential of visualisation to improve the ways in which thermal analysis data are presented to building services engineers, with a view to increasing the accuracy and efficiency of its interpretation. The approach taken throughout followed a pattern of research, development, demonstration and evaluation. The research phase included a detailed review of existing visualisation theory and an extensive user requirement survey. The development phase produced three working visualisation software prototypes, each of which was demonstrated or evaluated within the sponsoring company. Whilst the initial emphasis of the research was advanced Three-Dimensional (3D) visualisation, extensive user requirement analysis indicated that comparing multiple datasets in an intuitive manner was more important. In response, the research focused on combining techniques in ways which supported the rapid comparison of multiple files and the data contained within. The final prototype combines techniques for data storage and manipulation with information visualisation techniques and advanced 3D graphics. These elements are tightly integrated within a single application that facilitates the management and interpretation of data from multiple analysis models. Evaluation of the prototype showed high levels of user satisfaction and improvements in the accuracy and efficiency of data interpretation. The techniques demonstrated by the prototype were also understood and liked by the users of thermal analysis tools. Several of the techniques, such as the new Force Directed Difference Diagrams, have potential applications outside of building services engineering. The research has demonstrated it is possible to improve the representation and interpretation of building performance data using visualisation techniques.

Um estudo da realizaÃÃo da seqÃÃncia narrativa no gÃnero notÃcia

AurenÃvia Ferreira da Silva 26 February 2007 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Esta investigaÃÃo està centrada na anÃlise e descriÃÃo da realizaÃÃo da seqÃÃncia narrativa no gÃnero notÃcia, segundo o esquema prototÃpico narrativo de Adam (1992), e na verificaÃÃo de relaÃÃes existentes entre esse modelo seqÃencial e a estrutura propriamente dita do gÃnero. O corpus desta pesquisa foi constituÃdo por 50 notÃcias, dentre as quais 26 policiais e 24 nÃo-policiais, retiradas dos sites dos periÃdicos jornalÃsticos O Povo e Folha de SÃo Paulo, no perÃodo de setembro de 2005 a setembro de 2006, e submetidos à identificaÃÃo das macroproposiÃÃes narrativas em sua estrutura textual. A anÃlise realizada levou-nos a uma nova classificaÃÃo das notÃcias em narrativas e expositivas, de acordo, respectivamente, com a identificaÃÃo ou nÃo da seqÃÃncia narrativa na sua estrutura. A partir dessa classificaÃÃo, constatamos que a seqÃÃncia narrativa se atualizou predominantemente nas notÃcias policiais, que apresentaram uma forma de realizaÃÃo recorrente: a ocorrÃncia expressiva da seqÃÃncia narrativa, com todas as suas fases, no lead, e a constante repetiÃÃo ou retomada de algumas das macroproposiÃÃes narrativas no corpo da notÃcia, como uma extensÃo do conteÃdo jà exposto, configurando uma caracterÃstica do gÃnero. A seqÃÃncia narrativa funcionou como um importante mecanismo de organizaÃÃo textual das notÃcias narrativas, ainda que sua conformaÃÃo narrativa prototÃpica tenha sido diferente da delineada por Adam. Jà nas notÃcias nÃo-policiais, o rendimento foi baixo. A estrutura composicional recorrente que registramos configurou-se como expositiva e, nesse caso, a analisamos à luz dos pressupostos teÃricos de Bronckart (1999). Acreditamos ter possibilitado uma interessante reflexÃo teÃrica sobre a realizaÃÃo do protÃtipo da seqÃÃncia narrativa de Adam no gÃnero notÃcia e, do ponto de vista aplicado, esperamos ter contribuÃdo para a operacionalizaÃÃo do conceito de seqÃÃncia textual narrativa no tratamento didÃtico de gÃneros nÃo-literÃrios considerados de natureza narrativa, tal como o gÃnero notÃcia. / This research analyzes and describes the realization of the narrative sequences in the genre news of newspaper through the Michel Adamâs prototypical project of narrative sequences (cf. ADAM, 1992) and through the relations between this project and the proper structure of that genre. The corpus was formed by 50 news, being 26 about crimes and 24 about other subjects. They were extracted from the sites O Povo and Folha de SÃo Paulo from September/2005 to September/2006 and later they were submitted to identification of the narrative macro-proposals in its textual structure. After, the news were classified as narrative and expositive according to identification or not of the narrative sequence in its structure. From this classification, we observed that the narrative sequence became predominantly current in the news about crimes, presenting almost always the following form of realization: the expressive occurrence of the narrative sequence in the lead, with all its phases, and the constant repetition of some narrative macro-proposals in the text like a characteristic and an extension of the content of the genre news. So, the narrative sequence functioned as an important mechanism of textual organization of the genre news, although its prototypical conformation is different of that one thought by Adam. About the other kinds of news, the profit was low. Its recurrent compositional structure is expositive, therefore we analyze it with the theoretician proposals of Bronckart (1999). This way, we tried to make possible a theoretical reflection about the realization in the genre news of the prototype of narrative sequence thought by Adam, waiting to contribute for the operacionalization of the notion of narrative textual sequence through the didactic treatment of not-literary genres, but narrative genres such as the genre news.

Os sufixos agentivos -nte e-(d/t/s)or no português: um estudo semântico-diacrônico / The agentive suffixes nte and (d/t/s)or in the Portuguese language: a semantic diachronic study

Anielle Aparecida Gomes Gonçalves Jacometti de Oliveira 08 September 2014 (has links)
No processo derivacional, os sufixos nte e (d/t/s)or são conhecidos por formarem vocábulos designados na língua como agentivos. O conceito de agente, por sua vez, é fundamental para os estudos da linguagem, pois descreve uma categoria primária a qualquer ser vivo, servindo, por isso, de base para a criação de outras categorias. Propôs-se observar, descrever e organizar os significados dos sufixos nte e (d/t/s)or presentes na língua portuguesa, utilizando o mecanismo da paráfrase. Por tratar-se de afixos abrangentes, fizeram-se necessários dois tipos de abordagem: uma qualitativa e uma quantitativa. Num primeiro momento, fez-se uma pesquisa etimológica específica nos agentivos nomeadores de profissionais, isto é, em designadores de seres humanos portadores de uma função, em que se examinou o emprego primitivo dos sufixos que compõem essa análise. Depois, abarcaram-se palavras pertencentes a campos diversos, limitados pela presença desses sufixos. Os sufixos formadores de nomina agentis nte e (d/t/s)or remetem aos falantes a ideia de alguém ou algo que faz alguma coisa, isto é, forma duas séries nas quais se corporizam as derivações deverbais de designações de pessoas que são agentes da ação implicada no significado do verbo. A hipótese do trabalho é a de que os nomes em nte e (d/t/s)or possuem a propriedade do aspecto, entendido como duração da ação, devido à constituição histórica tanto das bases que os integram como dos próprios afixos, o que confere a cada um deles um papel semântico específico na língua. Constatou-se que as paráfrases dos nomes em nte e (d/t/s)or seguem um padrão acional único, sem variação nos diversos grupos lexicais a que pertencem, com uma especificidade no significado do sufixo nte. Esses e os outros elementos morfológicos se constituem como fundamento material para mediar a relação do falante com sua expressão social / In the derivational process, the suffixes nte and (d/t/s)or are known for forming words which are designated in the language as agentives. The term agent is fundamental to the studies of languages because it describes a primary category to any living being, and therefore it serves as a base to the creation of other categories. The proposal of this work is to observe, to describe and to organize the meanings of the suffixes nte and (d/t/s)or in Portuguese, utilizing the mechanism of paraphrase. Since they are comprehensive affixes, two approaches a qualitative and a quantitative one were necessary. Firstly, it was conducted a specific etymological research about the professional agentives, i.e. namely in human beings that have a function, in which the original function of the suffixes was examined. Subsequently, words of different fields were analyzed with these affixes. The nomina agentis forming suffixes nte and (d/t/s)or give to the speakers the idea of someone or something that does some action, forming two series in which they embody the deverbal derivations of nouns of people who are agents of the action implied in the verb meaning. The hypothesis of the work is that names in nte and (d/t/s)or own the property of the aspect, videlicet the implication of the duration of the action, due to historic constitution of both the bases and the affixes, which provides to each suffix one specific semantic role in the language. It was noticed that the paraphrases of the names in nte and (d/t/s)or follow one single standard of action, with no variation in the several and different lexical groups to which they belong, with a specificity in the meaning of the suffix nte. These and the other morphological components constitute the material base to mediate the relationship between the speaker and his/her social expression

Environnement de programmation parallèle: application au langage Prolog

Morel, Eric 14 November 1996 (has links) (PDF)
Cette thèse présente l'étude de l'implantation d'un système Prolog parallèle sur une architecture sans mémoire commune dans le cadre du projet PLoSys (Parallel Logic System). L'exécution exploite le parallélisme de manière implicite. Le système repose sur un modèle OU multiséquentiel. Le partage de l'état d'exécution est assuré par copie des données. Le langage Prolog supporté est complet, et intègre les effets de bord classiques du langage. La gestion parallèle fait l'objet d'une étude complète pour préserver la compatibilité avec l'exécution séquentielle du langage Prolog. En particulier, une méthode originale est présentée pour la gestion parallèle des effets de bord. Enfin, ce document présente la réalisation d'un prototype portable, ainsi que l'analyse des résultats obtenus
