Metáforas conceituais para design de hipermídias
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Design e Expressão Gráfica, Florianópolis, 2014A eficácia do design de hipermídias é dependente de muitos fatores, incluindo as abordagens de design e métodos seguidos. A era do desenvolvimento ágil trouxe problemas para as equipes de desenvolvimento que precisam criar rapidamente interfaces gráficas para hipermídias, o que fomentou o interesse na integração do design de experiência do usuário e desenvolvimento ágil. Devido a isso, um processo chamado "Rapid Metaphor Processing? foi proposto para auxiliar o desenvolvimento rápido de interfaces gráficas para hipermídias. Inicialmente, a teoria de Metáforas conceituais é analisada, remontando autores que indicam ser este um aspecto imperativo para a comunicação e interação humana com hipermídias. Uma abordagem baseada neste conceito é então definida como um processo de projeto, sob a hipótese de que é possível, com a manutenção paralela de um senso de design centrado no usuário, agilizar soluções criativas. O processo então foi aplicado em um workshop, em quatro diferentes projetos que utilizaram o sistema proposto para desenvolver hipermídias, tendo como objetivo analisar se o processo poderia melhorar a agilidade, o design centrado no usuário e a inovação dos produtos. Implicações de cada conceito são discutidas em detalhes para mostrar a importância e o valor do processo proposto para o processo global de design. Os dados sobre o uso do processo foram obtidos através de questionários pré e pós-workshop realizados com os participantes; bem como da observação do andamento do workshop e da análise da produção resultante. Verificou-se que o processo proposto amplia a velocidade de projetos de experiência do usuário para interfaces gráficas, ao mesmo tempo, promovendo a inovação e o design centrado no usuário.The effectiveness of the hypermedia design is dependent on many factors, including the design approaches and followed methods. The era of agile development has brought problems for development teams that need to quickly create graphical interfaces for hypermedia, which fostered the interest in the integration of user experience design and agile development. Because of this, a process called "Rapid Metaphor Processing" was proposed to aid the rapid development of graphical interfaces for hypermedia. Initially, the theory of conceptual metaphors is reviewed, tracing authors who indicate that this is an imperative aspect for communication and human interaction with hypermedia. An approach based on this concept is then defined as a design process, under the assumption that it is possible, with the parallel maintaining a sense of user-centered design, to streamline creative solutions. The process was then applied in a workshop in four different projects that used the proposed system to develop hypermedias, aiming to examine whether the process could improve the agility, the user-centered design and product innovation. Implications of each concept are discussed in detail to show the importance and value of the proposed process for the global design process. Data on the use of the process were obtained through pre and post workshop questionnaires conducted with the participants; as well as the observation of the progress of the workshop and analysis of the resulting products. It was found that the proposed method enhances the speed of user experience designs for graphical interfaces, while fostering innovation and user-centered design
Understanding and Tooling Translational Research in Human-Computer Interaction
No full textThesis (Ph.D.)--University of Washington, 2020Successfully bridging research and practice in Human-Computer Interaction (HCI) can lead to better products and services that benefit society, as well as refined research questions and theories. However, groups of HCI practitioners and HCI researchers often fail to benefit from each other’s valuable expertise, which led to the use of a “research-practice gap” metaphor to illustrates the hardships of bridging research and practice. Although the research-practice gap has framed and motivated studies and opinion pieces by HCI academics, there is still much to be understood about the relationships of research and practice in HCI. This dissertation investigates the nuances of the research-practice gap metaphor in HCI, and the knowledge exchange and use by different groups in the HCI community. Informed by such nuances, I design tools to bridge research and practice in HCI.First, I investigate the research-practice gap to expose the complexity underlying the stark separation between two groups. I study HCI community members’ current efforts to engage in Translational Research efforts, with a focus on knowledge consumption and utilization as well as barriers for knowledge to flow across groups. As a result, I propose a Translational Science Model using the concept of a continuum instead of a gap, to represent how knowledge flows in the HCI community through multiple gaps. I define and describe instances of Translational Research in the HCI field. In addition, I propose design considerations regarding the creation of resources and design methods to facilitate the translation of HCI knowledge from scientific findings to design. Through these contributions, the HCI community can better understand current practices around disseminating and translating HCI knowledge, and the challenges and opportunities for Translational Research to impact distinct design activities.
Second, to help bridge the research and practice gaps, I design and evaluate tools aimed at tackling specific barriers for Translational Research in HCI. Translational Research tools in HCI have been framed around academics’ knowledge dissemination models and needs. In turn, I propose and evaluate tools focused on practitioners’ needs and workflow. In one tool, I tackled the barrier of language by creating learning modules for HCI practitioners to read and understand theoretical concepts. On another tool, I tackled the barrier of applicability and contribute a design method to facilitate the application of existing theories into the design process. Learnings from these design explorations help to further furnish our knowledge on how to effectively implement Translational Research efforts and provide additional nuance on the barriers for knowledge dissemination and translation in HCI.
In summary, this dissertation introduces and defines Translational Research in HCI and provides a foundation for the discipline to investigate and design translational processes and tools. Such contributions will hopefully inspire efforts to consolidate a Translational Science in HCI
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
