Com o intuito de avaliar os problemas de acessibilidade em VUI, a presente pesquisa focalizou a proposição de uma abordagem de avaliação baseada em um conjunto de técnicas já conhecidas pela comunidade de IHC (Interação Homem-Máquina). No tocante a cada técnica utilizada, o problema foi focado a partir de diferentes perspectivas: (i) do usuário, expresso a partir das visões dos usuários sobre o produto, reunidas a partir de uma abordagem de avaliação; (ii) do especialista, expresso sob a forma de análise dos resultados dos desempenhos dos usuários em sessões de teste de acessibilidade; e (iii) da comunidade de acessibilidade, expresso com base em revisões de projeto, a fim de determinar se o projeto da interface está em conformidade com um padrão. Além disso, visando a evidenciar a incerteza associada aos julgamentos do avaliador na inspeção de conformidade do produto, incorporou-se a modelagem de incerteza, a partir da utilização de Redes Bayesianas, possibilitando ao avaliador explicitar os níveis de incerteza associados às inspeções de conformidade do produto a um padrão, por ele realizadas. A abordagem metodológica foi validada a partir de um estudo de caso envolvendo a avaliação da acessibilidade do sistema computacional DOSVOX, desenvolvido na Universidade Federal do Rio de Janeiro (UFRJ), com o objetivo de auxiliar usuários com deficiência visual no uso de sistemas computacionais. No enfoque da inspeção de conformidade, consideraram-se as partes 14 (Diálogos via menus), 17 (Diálogos via preenchimento via formulários) e 171 (Guia de acessibilidade de software) do padrão internacional ISO 9241. Por outro lado, nos enfoques da mensuração de desempenho e da sondagem da satisfação subjetiva do usuário, foram realizados testes de acessibilidade, envolvendo um universo amostrai de 100 usuários. Inicialmente, os participantes foram agrupados como cegos (40 usuários), baixa visão (20 usuários) e sem deficiência visual (40 usuários), de acordo com tipo de deficiência visual. Em seguida, eles foram classificados como principiantes (46 usuários) ou intermediários (54 usuários), de acordo com o nível de conhecimento em Informática e de experiência o produto avaliado. Os dados resultantes dos testes de acessibilidade foram processados estatisticamente, a fim de verificar a correlação entre os desempenhos dos grupos de usuários e entre o desempenho das categorias de usuários de cada grupo. O processamento estatístico dos dados evidenciou a inexistência de diferenças significativas entre os desempenhos dos grupos, bem como entre as categorias de usuários. Por outro lado, a confrontação dos resultados dos três enfoques (mensuração de desempenho do usuário, mensuração da satisfação subjetiva do usuário e inspeção de conformidade do produto a padrões) demonstrou que a abordagem de avaliação proposta produziu resultados complementares e reforçou a relevância da utilização de uma abordagem multimétodos para a avaliação de acessibilidade de interfaces vocais. / Voice interaction design per se does not provide quality assurance of the interactive process for visually impaired users. In this dissertation, a method for evaluating voice user interface (VUI) accessibility based upon a set of techniques already well-known to the HCI (Human-Computer Interaction) community is proposed. For each technique, the problem is focused from a different perspective: (i) the user's perspective, which is expressed as views on the product gathered from an inquiry-based approach; (ii) the specialist's perspective, which is expressed by the analysis of the performance results in accessibility testing sessions; and (iii) the accessibility community's perspective, which is expressed by design reviews to determine whether a user interface design conforms to standards. Additionally, Bayesian networks were used in order to make explicit the uncertainty inherent in conformity inspection processes. A case study with DOSVOX system was performed to validate the proposed approach. DOSVOX system was developed at Federal University of Rio de Janeiro (UFRJ) with the aim of helping visually impaired users use the computer. A conformity inspection was performed in accordance with parts 14 (Menu dialogues), 17 (Form-filling dialogues) 171 (Guidance on software accessibility) of ISO 9241. On the other hand, the user performance measurement and the user subjective satisfaction measurement were conducted via accessibility testing. One hundred subjects were enrolled in this study. First, they were categorized as blind (40 users), low vision (20 users) and non-visually impaired (40 users), according to their visual impairment. Second, they were grouped as novices (46 users) and intermediates (54 users), according to their knowledge level in Informatics and experience with the evaluated product. Accessibility test results were statistically analyzed in order to verify the correlation between category performances and between group performances. No statistically significant differences between the user categories or the user groups were found. On the other hand, data comparison showed that the three strategies adopted (user performance measurement, user satisfaction measurement and standard conformity inspection) add to the evaluation process, producing complimentary data that are significant to the process, and reinforcing the relevance of a multi-layered approach for the accessibility evaluation of voice user interfaces.

Para tanto, foram estudados os principais processos operacionais de uma loja de varejo de autosserviço, com vistas a identificar como as Tecnologias da Informação (TI) e de Identificação e Captura Automática de Dados (AIDC), poderiam ajudar a melhorar os resultados operacionais e agregar valor ao negócio. Para analisar suas proposições (de que o uso de TI e de AIDC podem ajudar na: redução dos tempos dos processos de retaguarda; redução do número de operações no ponto de venda; prevenção de perdas; redução dos custos e dos tempos para a realização dos inventários; redução do número de funcionários nas lojas; redução do tempo de fila no caixa; redução de rupturas e no aumento da eficiência operacional da loja), foram pesquisados diversos estudos de casos mundiais de empresas do segmento de varejo, que implementaram as tecnologias de AIDC e TI, principalmente a de RFID, para saber quais foram os impactos do uso destas tecnologias em suas operações e, em seguida, foi desenvolvido um Estudo de Caso abrangente, por meio do qual se objetivou entender os benefícios empresariais reais do uso destas tecnologias para o varejo de autosserviço. Como resultado final, foi possível identificar as mudanças nos processos operacionais do varejo de autosserviço, bem como os benefícios gerados em termos de custo, produtividade, qualidade, flexibilidade e inovação. O trabalho também evidenciou os pontos críticos de sucesso para a implementação da TI e das AIDC no varejo, que são: a revisão dos processos operacionais; a correta definição do hardware; dos insumos; do software; das interferências do ambiente físico; da disponibilização dos dados/informações dos produtos; das pessoas/funcionários e dos parceiros de negócios/fornecedores. De maneira mais específica, este trabalho buscou contribuir para o enriquecimento do campo de estudos no segmento de varejo e para o uso da tecnologia da informação, no Brasil, já que o assunto sobre o uso e o impacto de novas tecnologias no ponto de vendas, ainda permanece pouco explorado academicamente. / This study sought to identify the main IT technologies available for the AIDC and retail self-service area, to fill the gap in the literature about the real advantages of using new technologies at the point of sale, in order to optimize its operation. In order to do this, we studied the main operational processes of a self-service retail store bearing in mind to identify how the technologies of Automatic Identification and Data Capture and IT could help to improve the operating results and add value to the business. To analyze these proposals we have surveyed several global case studies of retail companies, which implemented the AIDC and IT technologies to investigate what were the impacts of using these technologies in their operations and then designed a comprehensive and innovative Case Study, through which we sought to understand the real business benefits. As a final result, it was possible to identify the changes and the benefits in terms of cost, productivity, quality, flexibility and innovation. The work also highlighted the critical points of success for the implementation of AIDC and IT Retail, which are: the review of operating processes, the correct definition of the hardware; inputs; software; interferences of the physical environment, the availability of data / information of products, of people / employees and of business partners / suppliers. More specifically, this study sought to contribute to the enrichment of the field studies in the retail segment and for the use of information technology in Brazil, since the issue on the use and impact of new technologies at the point of sales, still remains unexplored academically.

This paper describes a model-driven approach to create dynamically and manage these GUIs. In this approach, the Software Engineer designs conceptual models of the information system using object-oriented meta-models. A set of predefined mapping rules is applied to automatically transform and refine the conceptual models in order to generate, in runtime, the look and feel of the GUI, without source code creation. This improves the software usability, assuring consistency and homogeneity of the GUI, increases the productivity of the software engineering staff and simplifies maintenance. In our experiments we have observed an average productivity fifteen times higher than traditional methods of GUI development. / Construir e manter uma Interface Gráfica com Usuário (GUI) para Sistemas de Informação (SI) demanda muito tempo e esforço da equipe de Engenharia de Software. Esta dissertação descreve uma abordagem dirigida por modelos para criar dinamicamente e gerenciar essas interfaces. Nessa abordagem, o Engenheiro de Software projeta um modelo conceitual do sistema de informação usando um meta-modelo orientado a objetos. Um conjunto de regras de mapeamento predefinidas é aplicado para refinar e transformar o modelo conceitual do SI, gerando, em tempo de execução, a sua interface gráfica, com aparência e comportamentos específicos. Esse mecanismo melhora a usabilidade do software, assegurando consistência e homogeneidade das GUIs, aumenta a produtividade da equipe de Engenharia de Software e simplifica a manutenção do SI. Nos experimentos realizados foi observada uma média de produtividade quinze vezes maior do que os métodos tradicionais no desenvolvimento de GUIs.

One important phase in software development process is to create a design model of the system which follows all the architectural rules. Often the architectural rules are defined by the system architect and the system model is designed by the system designer. The architect defines the rules in a text file where no standard or pattern is followed. Therefore, there is always the risk of violating the architectural rules by the designer. So manual reviews on the system model should be done by the architect to ensure the system model is valid.In order to remove this manual checking which can be erroneous and time consuming ArCon (Architecture Conformance Checker) was developed by Combitech AB. ArCon is a tool which lets the architect define the architectural rules in the format of UML (Unified Modeling Language) models where the elements of the model have different meaning than the standard UML. ArCon can read this model and extract architectural rules from it and check the system model against those rules and then print all the rule violations.ArCon is an open source tool i.e. free for everyone to download and use. Currently, it supports Papyrus as the UML modeling tool. Papyrus is integrated to Eclipse platform and is a general purpose modeling tool. It supports users with all types of UML diagrams and elements.The idea for this thesis work was to implement a new feature for ArCon in order to facilitate the design process for system designers. The feature should provide the system designers only those types of elements which they are permitted to add to a specific fraction of the system model. The list of permitted element types should be extracted from the architecture model where all the architectural rules are defined in advance. This new support in ArCon was named Domain Specific Modeling (DSM) support.To evaluate the effect of DSM support on the system designers performance a few test sessions, called usability tests, were performed. The participants in the test sessions were a representative sample of software designers. After analyzing the data collected from the test sessions, the pros and cons of the new support were discovered. Furthermore, a few new ideas for enhancing DSM support were generated.

Det här arbetet syftar till att genom design av en telefonapplikation undersöka hur ljud kan förstärkas av den omgivande miljön. Arbetet visar på hur miljöförstärkt ljud skiljer sig från ljudförstärkt miljö samt vilka begränsningar det innebär att använda en vanlig smartphone som plattform.  Ett långsiktigt mål är att genom en produkt som låter oetablerade ljudproducenter distribuera sina alster i den offentliga miljön främja fri kultur och kreativitet. Arbetet har följt principen för RtD (research through design), där designprocessen utgör det fall som studeras och dokumentationen av den utgör den bas av data som analyseras och leder till slutsatser kring ämnet. Designprocessen i detta arbete innebär en mindre omfattande användarstudie i enkätform för att identifiera målgrupp, krav och mål. Följd av en andra studie där en prototyp framtagen med grund i resultaten från användarstudien utvärderas av deltagare genom observation, intervju och reaktionskort.  De största utmaningarna för designen grundar sig i att ta fram en applikation som inte stör upplevelsen, men samtidigt kan instruera användaren i hur man använder applikationen. Utifrån arbetet dras slutsatsen att användarinstruktioner, såväl visuella som auditiva, löper större risk att störa upplevelsen i miljöförstärkt ljud än i ljudförstärkt miljö. Vidare konstateras att den största bristen i en lösning som bygger på standardutrustning i jämförelse med en lösning som nyttjar dedikerad utrustning utgörs av begränsningar när det kommer till att ange riktning med hjälp av ljudets rumslighet.

Internet and websites are today one of the most important communication channels of almost all companies. They offer a simple, fast and effective way of communication, which is also available worldwide in a few seconds. With the globalization of market, more and more companies try to expand their business beyond the territory of the home state. In the current time of start-ups is the Internet also often a medium that allows formation of new spheres of business for which the website is absolutely essential channel. This type of business is internet based and has very often international ambitions from the very beginning. Given that each country (or region) can be seen as distinctive culture, it is advisable to locate websites for the needs of the foreign country. This is exactly the theme of this thesis. The concrete objective of this thesis is to offer a methodology for website localization in terms of webdesign. The basic building block is the delimitation of a multidisciplinary theoretical framework that examines the concept of culture and extensive literature review allowing current insight into the linking of website and culture, i.e. cultural website localization. Suitable method for gripping such a complex concept as a culture emerge from a theoretical framework as well. As the most appropriate method were determined Hofstedes cultural dimensions, which are then used for the analysis of cultural determination of web elements. Data collection for the purpose of analysis of web elements cultural determination is performed using a content analysis of websites from nine different countries. The results of the analysis are compared and synthesized with the findings stemming from a literature review. The final artifact of this thesis, a methodology for website localization from the perspective of web design, is based on this ground. Validation of the proposed methodology is done on the basis of assessment of the methodology for a domain of web design. This assessment is based on interviews with experts from different countries as well as presentation of concrete example of methodology use within a midsize website.

The main subject of this thesis is to prepare the web analysis and design methodology, MANW. The first part of the thesis is dedicated to the definition of the methodological framework on the basis of which the methodology will be built. The framework comes out from the methodological framework MEFIS which has been accustomed to comply with specific needs of the web application and websites development. The second part of the thesis is dedicated to the research of existing methodologies for web project implementation. Based on the research, the elements of the methodologies suitable for analysis and design are selected and then incorporated into the MANW methodology. The last part of the thesis is the description of the methodology itself and description of its characteristics and elements. The goal of the diploma thesis is to prepare a simple methodology for websites and web applications analysis and design which can be used in agile web development. The methodology is described by its phases, processes, roles, inputs and outputs and other elements which are defined in the elaborated methodological framework. The output of methodology processes are the data for implementation, deployment and operation of web solutions. It was necessary to define the term methodology and define a methodological framework first in order to work out the methodology itself successfully. Another starting point for methodology design was the research of existing methodologies which also serves as an introduction to the problems of web projects implementation and provides an overview of existing tools. Output of the thesis is the MANW methodology which is a synthesis of the working experience and of a methodological framework theory. This methodology is easily modifiable and thanks to the clear process definition it can provide the companies with an effective solution of web products analysis and design.

The topic of the thesis is costs in truck transport. There is analyzed theme Progress of costs in time, using indexes. The theoretical part is focused on the methodology for calculating the cost index published by the Czech Association of Road Carriers Česmad Bohemia and compared with several foreign indexes. The practical part has two objectives. The first focuses on the design of a new methodology that will be more accurate and reflect the true situation. The second objective of this methodology is to design basic informatics support, for both users, indexes users and persons, who are responsible for publishing these statistics. The summary points to the possibilities of alteration of the current designed index methodology and the potential for cooperation of Česmad Bohemia and Czech Statistical Office.

The object of this study was to assess the influence of native language, as a principal cultural characteristic, one users’ behavior when using a web-based e-commerce application. The study expands on previous research by comparing English and Russian users. The research also considered demographic data to assess additional factors that influence behavior and task performance. The research design encompassed an online shopping application with two different navigation menus. One menu was based on the action-object model and the other was based on the object-action model. The user interface was created in two different languages (Russian and English). This study suggests that language, as a cultural indicator, has a direct relationship to user satisfaction and performance in e-commerce web applications.

This thesis project explores how interactive technologies can facilitate a sense of social connectedness with others whilst remotely located. While studying the way humans use rituals for emotional management, I focused my interest on the act of commensality because it is one of the oldest and most important rituals used to foster togetherness among families and groups of friends. Dining with people who do not belong to the same household is of course hard during a global pandemic, just like many of the other forms of social interactions that were forcibly replaced by the use of technological means such as video-chat apps, instant messaging and perhaps an excessive use of social networking websites. These ways of staying connected, however, lack the subtleties of real physical interaction, which I tried to replicate with my prototype system, which consists of two sets of a lamp and a coaster which enable to communicate through light and tactile cues. The use of such devices creates a new kind of ritual based on the simultaneous use of the devices by two people, thus enabling a new and original form of commensality that happens through a shared synchronized experience.
