Cognitive user-centred design approach to improve accessibility for blind people during online interactionAl Jarallah, Khulud January 2013 (has links)
The use of internet and other communication technology has become predominantly common in the life of normal sighted users. In order to have a fair level of equality in the society, blind people must also be able to use these facilities with equal ease and effectiveness Many governments decided to implement e-Government applications to enhance the delivery of information and services to its citizens, residents and businesses. These e-Government applications were carefully designed with the help of international standards to serve the whole group of population and especially people with disabilities. However, recent studies showed that the acceptance rate of these e Government applications among the community, especially between people with disability, is not up to the expectations. The aim of this research is to investigate the accessibility issues faced by blind people while interacting with online services like e-Government portals Owing to the nature of content and the importance of information which is to be delivered to the whole country, the accessibility standards of such portals are of paramount importance. It is this idea of evaluation of such websites for special category of blind people that has been the main focus of this thesis. The main aim of this doctoral research is to discover any accessibility problems that could be faced by people with blind users during online interaction and not covered in accessibility standards. A real example of online interaction is the e-Government portals. This research followed a rigours tri-staged evaluation process for a selected e-Government portal (Saudi Arabian portal) to analyse the accessibility issues faced by blind people. The aim of this evaluation process is to understand the cognition and perception of a blind user while interacting with a web-based environment. The first step of the evaluation process was to verify the level of adherence of the selected portal to the Web Content Accessibility Guidelines (WCAG). The second stage includes a detailed experimental exercise with a number of blind people following the task- oriented approach. The third step of the evaluation process was a detailed interview with web designers to analyse the problems faced by blind participants in the experimental exercise. Thereafter, cognitive-based solutions were proposed to improve the accessibility of online interaction for blind users and fill the gap in the accessibility standards. The introduction of navigational landmarks and the insertion of virtual map description improve the navigation and hence the performance of blind users. The proposed solution has been tested with a separate group of blind users to validate the research findings and to ensure the desired level of accessibility of the e-Government portals is achieved.

Teams consisting of only software developers will occasionally need to develop products that has to be easy to use. User Centered Design (UCD) is one approach to help increase the ease of use of a product and that can be incorporated into the teams’ traditional workflow when needed. The software developer team followed in this thesis had not tried to incorporate UCD into their current workflow when developing such products. So, this thesis looks at how a product designed with an agile/UCD approach differs from a product developed by the software development team’s traditional approach. The two products were designed to solve the same problem. The results show that the product developed with an agile/UCD-approach gave better usability rankings and better external appeal than the one created with the team’s traditional approach. On the other hand, traditional methods constitute a better choice for quick development of products for more technical user groups within the company for example.
Utilizing user-centered design for the University of Victoria’s international connections mapping applicationMacek, Ian 05 December 2012 (has links)
This thesis explores the design of a website to communicate international activities undertaken by or associated with the University of Victoria. The research was seeded by and undertaken in collaboration with the University of Victoria’s office of Vice-President Academics and Provost, and the Office of International Affairs. The thesis introduces and implements a product design process to create a mapping application for the university to display all of its international connections. The thesis advanced the study of how to incorporate users into the design process of an online map. User-centered design is an established practice of studying users and collecting their feedback during all stages of design. This process has begun to be used for online mapping. A challenge with online mapping is that potential users can be an unwieldy community. In this case study the users could come from anywhere within the UVic community, but also the public. With such a large and diverse group, incorporating all the potential users into the design process is not possible. A challenge therefore is to capture feedback from a meaningful representative sample of potential users. This research describes a process of user-centered design in which a sample of users were surveyed at the beginning of the process to determine their requirements and preferences for a mapping application, and then interviewed to test the usability of the product. The thesis concludes with recommendations for design and layout of an online mapping application, including identification where further study or decisions are required. / Graduate

No. of bitstreams: 1 2997.pdf: 4158163 bytes, checksum: 540ba66fcb2c536c7a72d8add391f0b3 (MD5) Previous issue date: 2010-05-12 / Financiadora de Estudos e Projetos / The software reengineering becomes important because of the need that organizations have in adjusting to new trends, technologies and user requirements. The term organization should be understood like universities or companies that develop software for use by a large number of people. Thinking about the adequacy of users requirements, is presented in this work the reengineering process of a software called Cognitor, which is a tool designed to support teachers in the process of creating electronic teaching materials. The need to reengineer Cognitor was perceived through a case study where several changes were pointed by users. Some of these changes are: text editor improvement, preview of the images that are inserted in the content pages, feedback to the users, among others. During the reengineering of this software, it was formalized a software reengineering process model, user-centered, for the conversion of desktop applications in RIAs (Rich Internet Application), called UC-RIA (User Centered Rich Internet Application). The process model was named as UC-RIA due to the participation of the potential users during the application s reengineering process, because they were involved in prototyping and in validation of the graphical interfaces of the new version. The results of this study show the capability of the proposed software reengineering model to be used as a support in organizations for the reengineering of their software, mainly because it inserts the users in the reengineering process during the application s Prototyping phase, bringing software to users real needs. / A reengenharia de software se faz importante devido à necessidade que as organizações têm em se adequar às novas tendências, tecnologias e exigências dos usuários. Inclui-se ao termo organizações , empresas ou universidades que desenvolvem softwares para serem utilizados por um grande número de pessoas. Pensando na adequação das exigências dos usuários, este trabalho apresenta a reengenharia de um software chamado Cognitor, que é uma ferramenta criada para apoiar os educadores no processo de criação de material didático eletrônico. A percepção da necessidade da reengenharia do Cognitor se deu através de um estudo de caso onde foram relatadas várias alterações que o software deveria sofrer, tais como: melhoria no editor de texto, pré-visualização das imagens que são inseridas nas páginas de conteúdo, feedback ao usuário, entre outras. Durante a reengenharia desse software, consequentemente, foi formalizado um modelo de processo de reengenharia de software, centrado no usuário, para a conversão de aplicações desktop em RIAs (Rich Internet Application), denominado UC-RIA (User Centered Rich Internet Application). Foi dado o nome de UC-RIA ao modelo de processo devido à participação dos potenciais usuários da aplicação durante o processo de reengenharia, pois estes estiveram envolvidos tanto na prototipação, quanto na validação das interfaces gráficas da nova versão. Os resultados obtidos neste trabalho mostram a potencialidade do modelo de reengenharia de software UC-RIA em ser utilizado como apoio às organizações durante a reengenharia de seus softwares, principalmente por inserir os usuários no processo de reengenharia durante a fase de Prototipação da aplicação, aproximando os softwares às reais necessidades dos usuários.
In response to climate change, there is a growing need for the UK to reduce carbon emissions in the domestic sector. As a majority of energy consumed within the domestic sector is as a result of space and water heating, research in the field focuses on thermal comfort. The literature on thermal comfort is dominated by an examination of the physiological aspects, and although the influences of psychological and socio-cultural aspects are often recognised, their relationship to the physiological aspects is not fully understood. Additionally, the literature typically studies various elements of comfort (e.g. thermal, acoustic, lighting, etc.) in isolation to each other rather than taking a holistic approach which would mirror how they are experienced in the real world and identify potential associations. As a result, this thesis explores the multi-dimensions of comfort in the domestic environment. This research begins by taking a user-centred approach to exploring UK householders perspectives of comfort in the home. Through interviewing householders, the findings revealed householders attributed a wide scope of factors to their own experience of comfort, from aesthetics to feeling secure in their home; the findings highlighted the significance of psychological factors to householders comfort. The following stage involved a focused and in-depth exploration of the psychological dimensions of domestic comfort through photo elicitation interviews. The findings supported the presence of four intertwined psychological dimensions and further established the multidimensional nature of comfort. The final study was conducted to establish when comfort and unwinding takes place in householders everyday lives. Through the use of two self-reporting ethnographic tools, namely SenseCams and diaries, householders were observed in their homes. The findings captured householders engaging in various comfort making activities and also demonstrated the value of using self-reporting tools in the home context. In the final stage, a classification of domestic comfort was generated which presents an accumulation of the findings from this research to produce a holistic and multi-dimensional notion of domestic comfort.
Enhancing Accessibility of Web Based GIS Applications through User Centered Design / Ökad tillgänglighet av webbaserade GIS-applikationer genom användarcentrerad designBabar, Shahzad, Mehmood, Aamer January 2010 (has links)
Web Accessibility emerged as problem when disabled and elder people started interaction with web contents soon after the inception of World Wide Web. When web based GIS applications appeared on the scene of web and users of these kinds of applications increased, these applications faced the similar problem of accessibility. The intensity of web accessibility problems in GIS based applications has increased rapidly during recent years due to extensive interaction of user with maps. Web Accessibility problems faced by users of GIS applications are identified by content evaluation and user interaction. Users are involved in identification of accessibility problems because guidelines and automated tools are not sufficient for that purpose. User Centered Approach is used to include users in the development process and this has also helped in identification of accessibility problems of the users at early stages. The thesis report identify the accessibility issues in Web based GIS application by content evaluation and user interaction evaluation. MapQuest, a web based GIS application, is taken as a case study to identify the web accessibility problems in GIS applications. This thesis report has also studied that how accessibility of the web based GIS applications can be enhanced by using UCD approach in development process of GIS applications. / Webbtillgänglighet fram som problem när funktionshindrade och äldre människor började interaktion med webb-innehåll strax efter starten av World Wide Web. När webbaserade GIS-applikationer på scenen av webb och användare av dessa typer av tillämpningar ökat, dessa tillämpningar mötte liknande problem med tillgängligheten. Intensiteten av problem webbtillgänglighet i GIS-baserade applikationer har ökat snabbt under senare år på grund av omfattande interaktion med användaren med kartor. Webbtillgänglighet problem som användare av GIS-applikationer är identifierade med innehåll utvärdering och interaktion med användaren. Användare delta i identifieringen av tillgänglighetsproblem eftersom riktlinjer och automatiserade verktyg är inte tillräckliga för detta ändamål. Användarcentrerad metoden används för att inkludera användarna i utvecklingsprocessen och detta har också bidragit till en kartläggning av tillgängligheten problem för användarna i ett tidigt skede.

Denna uppsats Rapporten har också studerat hur att tillgängligheten av webbaserade GIS-applikationer kan förbättras med hjälp UCD strategi i processen för utveckling av GIS-applikationer.
How might we decrease the amount of information lost between and during night shifts through implementing a digital alarm register?Brandt, Julia January 2020 (has links)
This thesis explores the digital opportunities at a mobile workplace in elderly home care by analyzing the existing information and communication flow that happens between and during shifts in everyday practice using a user-centric approach. The fieldwork analysis reveals that a combination of media, both verbal, digital and paper-based is used throughout the shift to pick up and pass on information. With an ageing population that requires care from home, to sustain and improve the quality of care, my research indicates an evident need of supporting home care workers whilst being out of office.The research question is: “How might we decrease the amount of information lost between and during night shifts through implementing a digital alarm register?” which evolved from one out of four design opportunities.The main participants and focus throughout this study are the end-users, night shift home care workers at two different locations in the Malmö municipality. By involving the users early in the process, having a rich fieldwork process and putting emphasis on “support” rather than “replacement” resulted in a mobile application tool presenting relevant patient information, current alarms and alarm history.
Promoting Universal Access to E-government Services --- A Comprehensive Conceptual Framework from Citizens' PerspectiveAl Drees, Asma Ayed S. 26 June 2023 (has links)
The world moves toward the era of a smart society that is human-centered, sustainable, and inclusive. Countries employed new information and communication technologies to deliver services and engage citizens in the decision-making process. These services are evolving and in the near future, we can expect a plethora of new services related to Smart Society 5.0 and Industry 4.0, in addition to more traditional services. The possibility of these new technologies to foster sustainable development can only be obtained when all target users have fair access to the offered services. In the e-government context, ensuring service quality is crucial for success. While many factors contribute to service quality, user experience is becoming increasingly important. Governments need to put citizens at the center of the design process of their services and ensure that all target users have an enhanced experience with the offered e-services. Moreover, e-government constantly changes over time and continues to drive opportunities and open new possibilities for potential developments. Therefore, it is highly recommended that government agencies regularly evaluate citizens' experience with the offered services and investigate the factors that significantly influence their adoption behavior. However, numerous research efforts investigated the user experience of e-government from the lens of specific government services in an individual or specific range of countries. There has been a lack of a global e-government adoption framework to evaluate users' adoption behaviors of e-government services. Despite successful efforts to formalize certain aspects of user experience, there remains a need for a comprehensive and systematic framework for user experience evaluation. Therefore, the main objective of this thesis is to conduct a comprehensive study of the state of the art in user experience evaluation and develop a unified framework that integrates existing knowledge on the topic. It provides a systematic approach for enhancing user experience by providing guidelines on how to evaluate users' adoption behaviors of e-government services efficiently as a reference for future investigations. The research approach was conducted through two main phases. The first phase aims to design the proposed conceptual framework to evaluate users' adoption behaviors of e-government services. Hence, we have conducted a systematic literature review on user experience towards e-government services and cover all different aspects to better understand target users and enhance their overall experience. This systematic review informed the design of a holistic conceptual framework by investigating factors that significantly affect users' adoption of e-government services globally. The proposed framework provides a standard overarching process for future research in the e-government domain by providing an established methodology for evaluating users' adoption behaviors of e-government services. This framework is global, it is used to evaluate users' adoption behaviors of e-government in any country to ensure that citizens have a good experience with e-government services in that country. The framework includes the most common significant factors influencing users' adoption behaviors of e-government that represent the necessary steps to enhance citizen experience and boost their adoption behavior. The second phase implies the utilization of the proposed framework to evaluate users' adoption behaviors of e-government by developing a reference implementation of e-government adoption based on the proposed framework. The quantitative research methodology was employed using a web-based questionnaire to evaluate the e-government adoption behavior. The questionnaire contains a set of measurement items pertaining to each factor that existed in the proposed framework to investigate their potential relationships. The questionnaire underwent an iterative process of testing and validation to ensure the reliability and credibility of the measurement items. Then, the multivariate statistics, including the structural equation modeling, have been adopted to analyze and examine the framework relationships. Preliminary results of this thesis include two user studies investigating user experience towards specific e-government services to support the development of the conceptual framework. Then, the proposed framework alongside the reference implementation were applied to evaluate the Saudi e-government adoption by evaluating the adoption behavior and developing an explanatory model for the adoption behaviors of Saudi citizens. The contributions of this thesis can be summarized by conducting a systematic literature review on user experience towards e-government services to inform the design of the proposed framework. Then, developing a global conceptual framework for evaluating users' adoption behaviors of e-government. Overall, this thesis provides valuable insights into enhancing citizen experience and increasing their adoption of e-government services, which supports government agencies, practitioners, and policymakers. / Doctor of Philosophy / Governments employed new technologies that are dynamic and smart to deliver services to citizens and ensure they are engaged while using these services. Nowadays, the phenomenon of 'smart society' refers to systems that are human-centered, sustainable, and accessed by all target users.

In the literature, there has been a lack of a comprehensive review of user experience towards e-government services globally. In addition, many research efforts focused on developing e-government adoption frameworks based on government services in a specific country or a limited range of countries. There has been a lack of a global e-government adoption framework to evaluate users' adoption behaviors of e-government services. Despite successful efforts to formalize certain aspects of user experience, there remains a need for a comprehensive and systematic framework for user experience evaluation.

This comprehensive review informed the design of a holistic conceptual framework by investigating significant factors influencing users' adoption behaviors of e-government services globally. Hence, the proposed framework includes the most common significant factors influencing users' adoption behaviors of e-government imported from the comprehensive review's results. This framework provides a standard overarching process for future research in the e-government domain by providing an established methodology for evaluating users' adoption behaviors of e-government services. It is used to evaluate the e-government adoption behaviors in any country to ensure the efficiency of e-government services and enhance the citizen experience in that country. The quantitative research methodology was employed using a web-based questionnaire to evaluate the e-government adoption behavior based on the proposed framework. The questionnaire was tested and validated to ensure the reliability and credibility of the questionnaire items. After that, specific statistical techniques, including structural equation modeling, were used to examine and refine the framework relationships. Preliminary results of this thesis include two user studies investigating users' experience towards specific e-government services to support the development of the conceptual framework. Hence, the proposed framework alongside the developed questionnaire and implemented analysis techniques were applied to evaluate the Saudi e-government adoption by evaluating the adoption behavior and developing an explanatory model for the adoption behaviors of Saudi citizens. This thesis supports the e-government by providing valuable insights to government practitioners and policymakers on enhancing citizen experience and increasing their adoption of e-government services.
