In order to compile a comprehensive representation of the available guidelines regarding interface design for an elderly audience, the available literature was scoured. A prototype interface was then produced based on the guidelines produced from this in combination with previously established needs among elderly that are subject to home care. Six subjects participated in a series of usability test that were implemented to evaluate the design of the prototype, along with complementary interviews that served to investigate the subject’s attitudes towards such a product that the prototype represents in general. The chosen method for these usability tests proved problematic and appropriate measures had to be implemented in order for the tests to produce adequate data. The results of the attuned method showcased an expected animosity towards the type of technology used in the tests while at the same time demonstrating the perceived redundancy in the product due to already established systems in use by the subjects as well as the requirements for such a product to be viable. That is primarily the extended ability to contact and/or communicate with caregivers that such a product offers.

[pt] Através desta dissertação, foi possível avaliar e definir recursos ergonômicos de áudio com análises de sites corporativos da Internet, para posteriormente verificar a aceitação destes recursos pelo usuário. Inicialmente, foram apresentados conceitos relativos à utilização de áudio em sites da Internet para melhor compreender os processos relacionados. Depois, foram realizados procedimentos para delimitar amostras e avaliar os efeitos dos recursos ergonômicos de áudio na experiência do usuário. Verificou- se que a adequação dos recursos ergonômicos de áudio é um fator primordial em sites que utilizam áudio na Internet e a falta de testes com o usuário no processo de desenvolvimento de sites compromete o uso do áudio. Sem conhecer o modelo- mental do usuário, não há como definir os quesitos mais importantes relacionados ao áudio. Percebeu-se também a importância de organizar resultados para auxiliar no desenvolvimento de projetos que envolvam aspectos ergonômicos ou de usabilidade. Assim, conclusões sobre os principais recursos ergonômicos de áudio foram apresentadas em seções distintas para facilitar sua aplicação. / [en] This thesis evaluated and defined audio ergonomic resources through the analysis of corporative sites from Internet, verifying the acceptance of these resources with the user. Initially, related concepts to audio application in sites of the Internet were presented to better understanding envolved processes. Later, procedures had been carried through to establish scopes and audio ergonomic resourses effects in the user experience were evaluated. It was noted that the adequacy of audio ergonomic resources is a primordial factor in sites that use audio in the Internet and the lack of tests with the user in the process of development of sites compromises the audio applications. Without knowing the mental-model of the user, it is impossible to define the most important itens related to audio. The importance of organizing research data results to assist in the development of projects that involve ergonomic or usability aspects was also noted. Thus, conclusions on the main audio ergonomic resources had been presented in distinct sections to facilitate its applications.

Thesis advisor: James Gips / This paper examines the impact of a multicultural approach on the usability of web and software interface designs. Through the use of an eye-tracking system, the study compares the ability of American users to navigate traditional American and Japanese websites. The ASL R6 eye-tracking system recorded user search latency and the visual scan path in locating specific items on the American and Japanese pages. Experimental results found statistically significant latency values when searching for left- or right-oriented navigation menus. Among the participants, visual observations of scan paths indicated a strong preference for initial movements toward the left. These results demonstrate the importance of manipulating web layouts and navigation menus for American and Japanese users. This paper further discusses the potential strengths resulting from modifications of interface designs to correspond with such cultural search tendencies, and suggestions for further research. / Thesis (BA) — Boston College, 2005. / Submitted to: Boston College.

The evolution of Patient Reported Outcomes (PROs), has made an essential impact on patient-centered symptom management. PROs enable us to measure the patient‘s feels about their symptoms during treatment. ePROs (electronic PROs) are interfaces that allow a patient or health care provider to manage symptoms using an application such as mobile computing applications. The growth of mobile technologies in the healthcare sector has enabled us to take advantage of features like data manipulation, portability and standardization enable a better patient-driven symptom management. The Pan-Canadian Oncology Symptom Triage and Remote Support (COSTaRS) is a paper-based symptom management guideline designated for nurses. The objective of COSTaRS is to help and improve the decision-making process and create a consistent symptom management reporting system. Although this tool introduces numerous advantages in cancer symptom management, it also induces a number of issues for patients due to being overwhelming. Moreover, a noticeable portion of drawbacks originates from the paper-based nature of COSTaRS. In addition, cancer care symptom management mobile applications do not offer proper evidence-based centered symptom management system to the users. The purpose of this study is to design and developed the mobile version of COSTaRS for patients and caregivers. We identify problems with the current paper-based structure and related academic and non-academic works and then, we design and evaluate a mobile version of COSTaRS that takes advantage of advances in mobile technology. We leverage COSTaRS knowledge to create a mobile application for symptom management. We create an evidence-based platform for cancer treatment-related symptom management. A usability testing has been conducted for evaluation of the COSTaRS mobile application. The results of this study verify the usability of COSTaRS mobile application.

Coleções digitais de mídias, tanto pessoais como online, crescem rapidamente. Para que grandes quantidades de músicas sejam acessíveis à usuários, serviços populares como iTunes, Last.fm e Pandora oferecem recomendações. Essa abordagem livra usuários de lembrarem de músicas, e permite a descoberta de canções novas ou esquecidas. Mas recomendações apresentam problemas com usuários, como credibilidade e falta de controle. A motivação deste trabalho é melhorar a experiência de usuários com recomendações de música através do uso de explicações. Ao usar um sistema de recomendação, a satisfação e aprovação de usuários não depende só da eficácia do algoritmo, mas também de explicações. Pesquisas mostram que estas podem beneficiar sistemas de recomendação, aumentando a credibilidade e satisfação de usuários, ao oferecer mais transparência e formas de correção. O objetivo deste trabalho é projetar e desenvolver uma nova forma de visualização de tags, e testar sua viabilidade para explicar e filtrar recomendações de músicas. Mais precisamente, investigamos se esta visualização pode favorecer as metas de inspeção (scrutability), eficiência, eficácia e satisfação. A partir da pesquisa em necessidades de usuários para recomendações e música, a visualização Tag Strings foi projetada e desenvolvida. Tag Strings inclui tanto a interface da visualização, quanto o processo de coleta e cálculo de relevância de tags e músicas. Para a avaliação da visualização Tag Strings, dois tipos de experimentos foram construídos: a comparação entre uma lista de recomendações com Tag Strings, e a comparação entre o design de referência (baseado nos serviços Last.fm e Pandora) e Tag Strings. A construção desses dois experimentos permitiu a avaliação de Tag Strings como uma forma de explicação para recomendações de música. Os resultados dos experimentos evidenciam que a nova forma de visualização Tag Strings favorece as metas de inspeção (scrutability), eficiência, eficácia e satisfação, melhorando a usabilidade e experiência de usuários com recomendações de música. / Digital media collections, both personal and online, grow rapidly. To make large music collections available to users, popular services such as iTunes, Last.fm and Pandora offer recommendations. This approach frees users from searching for music, and allows for the discovery of new or forgotten items. But recommendations present issues such as user trust and lack of control. The motivation for this project is to improve user experience with music recommendations through explanations. While using a recommendation system, user acceptance and satisfaction depends not only on the algorithm effectiveness, but also on explanations. Research shows that recommendations benefit from explanations, increasing user trust and satisfaction by offering more transparency and scrutability. The goal of this project is to design and develop a new form of tag visualization, and test its feasibility to explain and filter music recommendations. We specifically investigate if the visualization can support the aims of scrutability, efficiency, effectiveness and satisfaction. Based on the user research and needs for music recommendation, the visualization Tag Strings was designed and developed. Tag Strings includes both the visualization interface and the process of collecting and calculation of tag and track relevancy. To evaluate the visualization Tag String, we designed two types of experiments: comparing Tag Strings with a recommendation list, and comparing Tag Strings with a design reference (based on the services Last.fm and Pandora). The design of these two experiments allowed the evaluation of Tag Strings as a form of explanation to music recommendation. The experiment results highlight that the new visualization Tag Strings favors the aims of scrutability, efficiency, effectiveness and satisfaction, improving the user experience with music recommendations.

O principal objetivo do desenvolvimento de aplicações multimodais é possibilitar uma maneira mais natural dos seres humanos se comunicarem com as máquinas, por meio de interfaces mais eficientes, intuitivas, fáceis de usar e, de certa forma, mais inteligentes. No entanto, a literatura da área mostra que a reutilização, tanto de conhecimento como de código fonte, ainda apresenta problemas, dados a complexidade do código em sistemas multimodais, a falta de mecanismos eficientes de testes de usabilidade e a dificuldade em se gerenciar a captura, o armazenamento e a recuperação de conhecimento de projeto. Nesta tese argumenta-se que a utilização de uma abordagem sistemática, centrada no usuário, apoiada por uma ferramenta computacional e com um modelo bem definido que permita o desenvolvimento de interfaces multimodais com a reutilização de Design Rationale, aumenta e melhora os níveis de usabilidade, promove a identificação e utilização de padrões de projeto e o reúso de componentes. Para demonstrar esta tese, apresenta-se neste texto a abordagem para o desenvolvimento de interfaces multimodais Web, MMWA, e o seu ambiente de autoria, o MMWA-ae, ambos compostos por atividades que auxiliam a equipe de projeto durante as fases de projeto, desenvolvimento e avaliações de usabilidade. São discutidos também os resultados obtidos com a execução de três estudos de caso, realizados no ambiente acadêmico, nos quais se buscou determinar a viabilidade da abordagem e os benefícios que podem ser alcançados com a combinação de diferentes técnicas, a saber: design rationale, padrões de projeto, modelagem de tarefas, componentes de software, princípios de usabilidade, avaliações heurísticas, testes com usuários, regras de associação, entre outras. Os resultados evidenciam que a abordagem e seu ambiente de autoria podem proporcionar diferentes benefícios para organizações que desenvolvem sistemas multimodais, incluindo o aumento da usabilidade e consequentemente da qualidade do produto, bem como a diminuição de custos e da complexidade do desenvolvimento com a reutilização de código e de conhecimento capturado em projetos anteriores / The main goal of developing multimodal applications is to enable a more natural way of communication between human beings and machines through interfaces that are more efficient, intuitive, easier to use and, in a certain way, more intelligent. However, the literature shows that the reuse of both knowledge and source code still presents problems, given the complexity of the code in multimodal systems, the lack of efficient mechanisms to test the usability and the difficulty in managing the capture, the storage and the recovery of design knowledge. In this thesis it is discussed that the use of a systematic approach, usercentered, supported by a computer tool and with a well defined model that allows the development of multimodal interfaces with the reuse of DR, increases and improves the usability levels, promotes the identification and the use of design patterns and the reuse of components. To demonstrate this thesis, it is shown in this text an approach to develop Web multimodal interfaces (MMWA) and its authoring environment (MMWA-ae), both composed of activities that help the design team during the different project phases: design, development and usability evaluation. We also discuss in this thesis the results obtained with the execution of three case studies, executed in the academic environment, which aimed to determine the feasibility of the approach and the benefits that can be achieved with the combination of different techniques, such as: design rationale, design patterns, tasks model, software components, usability principles, heuristic evaluations, user testing, association rules, among others. The results show clearly that the approach and its author environment can provide different benefits to organizations that develop multimodal systems, including the usability improvement and, consequently, the quality of the product, as well as the decrease of costs and complexity since it encompasses the development with reused code and design knowledge captured in previous projects

O crescente uso das tecnologias digitais no dia-a-dia das pessoas gerou diversas mudanças de comportamento; tendências colaborativas de troca e compartilhamento de informações, ideias, conhecimentos e bens materiais passam a integrar não apenas a vida social dos usuários da internet, mas também surgem no ambiente escolar e de trabalho, mediadas por diferentes interfaces e dispositivos digitais. Nesse contexto, esta pesquisa pretende compreender como as ferramentas que surgiram a partir do uso das novas tecnologias de informação e comunicação (TICs) impulsionaram ou facilitaram a colaboração entre usuários na internet, abordando os principais aspectos e necessidades da colaboração em ambientes virtuais e relacionando-os com conhecimentos da área do design de interfaces O principal objetivo do estudo é propor elementos de interface que, integrados aos ambientes virtuais de aprendizagem (AVAs), favoreçam a realização de atividades colaborativas. Para tanto, após revisão bibliográfica e análise de similares, foi realizada uma análise das ferramentas colaborativas na interface do AVA Moodle, sob o aspecto dos mecanismos de conversação, coordenação e percepção de Preece, Rogers e Sharp (2005). Em seguida, foi aplicado um questionário com professores da área de design a respeito do uso do Moodle e/ou de demais tecnologias digitais em atividades colaborativas com os alunos. Os resultados dessa etapa foram discutidos em uma oficina com especialistas do campo de design a fim de avaliar as possibilidades de implementação de elementos gráficos e ferramentas computacionais na interface do Moodle que pudessem facilitar a colaboração entre seus usuários. Esses procedimentos elucidaram um conjunto de necessidades, requisitos, elementos e funcionalidades de interface com vistas a apoiar a colaboração em AVAs e/ou outras plataformas digitais. / The increasing use of digital technologies in people's daily lives has generated a number of behavioral changes; collaborative tendencies of exchange and sharing of information, ideas, knowledge and material goods integrate not only the social life of internet users, but also arise in the school and work environment, mediated by different interfaces and digital devices. In this sense, this research aims to understand how the tools that have emerged from the use of the new information and communication technologies (ICTs) have driven or facilitated Internet user’s collaboration, addressing the main aspects and needs of collaboration in virtual environments, relating them to interface design topics. The main objective of the study is to propose interface elements that, integrated to the interface of learning management systems (LMS), promote the accomplishment of collaborative activities To do so, after a literature review and the analysis of interfaces with collaborative functions, an analysis of Moodle's collaborative tools was carried out considering the mechanisms of conversation, coordination and awareness (PREECE; ROGERS; SHARP, 2005). Then, a questionnaire was applied with professors from the design area regarding the use of Moodle and/or other digital technologies in collaborative activities with their students. The results of this stage were discussed in a workshop with design experts, in order to evaluate the possibilities of implementing graphic elements and computational tools in Moodle's interface that could facilitate user's collaboration. These procedures have generated a set of needs, requirements, interface elements and functionalities to facilitate collaboration processes in learning management systems and/or other digital platforms.

Although Internet booking system has reached its peak in the recent years many previous researches say there is always a growing interest in the role and nature of design in HCI principles. Small difference can create a large impact in the business of Internet booking system. The future of any online booking system will be heavily depended on how easy and how friendly the system is designed. In our thesis, we are going to suggest what aspects of usability principles are important in making the user interface of current flight booking systems to reach a high degree of usability. For the above purpose we will find usability flaws in the current user interface design of flight booking systems and highlight the potential factors or aspects that make user interface more acceptable to users. To reach this purpose we will use a case study and analyze using an explanation building technique. The empirical data was collected through satisfaction questionnaire which was based on nine “preset tasks” which are designed depending on various usability principles. In our thesis, we will create an understanding on the aspects of usability principles used to make a user interface more acceptable to the users. This understanding will lead future researches in the betterment of interface design of flight booking system.

We identified that this value is manifested in the design of digital interface so expressive, and more specifically, the use of this value to the development of collaborative virtual environments. We found that these measures can increase greats benefits to social development and design in turn, would be the connection between the user and the field of technology innovation and science. We understand in this study, cases in which authorship in interface design can encourage collaboration between users of digital networks, in favor of an approaching to understanding of what it is for the designer acting to contribute to the development of this framework delimiting. These questions were conducted based on the inquiries from Foucault, Barthes and Michael Rock about the authorship, the considerations of Pierre Levy, Steve Johnson and Lucia Santaella to the ramifications of cyberspace, and the placement of Gui Bonsiepe about design in the digital age. Among other authors who were important in development. Finally, we conclude that the designer s role in this context is of essential importance, and that the demonstration through the critical approach to the designer value of mediated authorship, attaches to the development of design projects for collaborative media interface, the application field innovation networks to these conditions by allowing the user to more natural interaction with cyberspace / A temática: autoria torna-se de grande relevância na revolução digital, movimentando uma vasta ordem de debates na sociedade. Identificamos que esse valor se manifesta no design de interface digital de maneira expressiva e, mais especificamente, no emprego desse valor ao desenvolvimento de ambientes digitais colaborativos. Constatamos que essas medidas podem trazer grandes benefícios ao desenvolvimento social e o design, por sua vez, é o meio de ligação entre o usuário e o campo da inovação da tecnologia e da ciência. Compreendemos, nesse estudo, processos em que a autoria no design de interface pode favorecer a colaboração entre usuários das redes digitais, em prol da aproximação de uma compreensão do que cabe ao designer desempenhar para contribuir com o desenvolvimento desse contexto delimitado. Esses questionamentos foram conduzidos com base nas contribuições de Foucault, Barthes e Michael Rock a respeito da autoria, nas considerações de Pierre Lévy, Steve Johnson e Lucia Santaella sobre os desdobramentos da cibercultura, e nas colocações de Gui Bonsiepe referentes ao design na era digital; entre outros autores que foram importantes nesse desenvolvimento. Por fim, concluímos que o papel do designer nesse contexto é de essencial importância e que a manifestação por meio da abordagem crítica desse profissional, mediada pelo valor autoria, confere ao desenvolvimento do design de interface de meios colaborativos, a inscrição no campo da inovação a essas redes ao permitir ao usuário condições cada vez mais naturais de interatividade com o ciberespaço

In driving, multiple variables in automated systems such as adaptive cruise control (ACC) and active steering, and in the environment dynamically change and interact. This complexity makes it difficult for operators to track the activities and responses of automation. The inability of operators to monitor and understand automation's behavior contributes to inappropriate reliance, i.e. when an operator uses automation that performs poorly or fails to use automation that is superior to manual control. The decision to use or not use automation is one of the most important an operator can make, particularly in time-critical or emergency situations, therefore it is essential that an operator is calibrated in their automation use. An operator's decision to rely on automation depends on trust. System feedback provided to the operator is one means to calibrate trust in automation in that the type of feedback may differentially affect trust. The goal of this research is to help operators manage imperfect automation in real-time and to promote calibrated trust and reliance. A continuous information display that provides information on system behavior relative to its operating context is one means to promote such calibration. Three specific aims are pursued to test the central hypothesis of this dissertation that continuous feedback on the state and behavior of the automation informs operators of the evolving relationship between system performance and operating limits, therefore promoting accurate mental models and calibrated trust. The first aim applies a quantitative model to define the effect of understanding on driver-ACC interaction failures and to predict driver response to feedback. The second aim presents a systematic approach to define the feedback needed to support appropriate reliance in a demanding multi-task domain such as driving. The third aim assesses the costs and benefits of presenting drivers with continuous visual and auditory feedback. Together these aims indicate that continuous feedback on automation's behavior is a viable means to promote calibrated trust and reliance. The contribution of this dissertation is in providing purpose, process, and performance information to operators through a continuous, concurrent information display that indicates how the given situation interacts with the characteristics of the automation to affect its capability.
