Este trabalho relaciona elementos das áreas de Computação e Saúde para comporem a elaboração de uma metodologia para avaliação de usabilidade de sistemas de transcrição automática de laudos na área de Radiologia. Inicialmente, é apresentado um estudo realizado sobre a área de Interface do Usuário Baseada em Voz que identifica requisitos para os sistemas que trabalham com comunicação mediada por voz assim como as iniciativas no sentido de se criar uma metodologia para sua avaliação. Em seguida é realizado um estudo dos sistemas de transcrição automática de laudos, no qual os principais requisitos são caracterizados e classificados. Os dois estudos acima citados foram integrados para a elaboração de uma metodologia para a avaliação de Sistemas de Transcrição Automática de Laudos em Radiologia. A metodologia foi, então, validada previamente através de inspeções e testes de usabilidade realizados fora do ambiente hospitalar, através do uso de um sistema de transcrição automática de laudos em Radiologia. Posteriormente, a metodologia foi também aplicada a um hospital da cidade de São Paulo. Como resultado principal foi proposto um guia bastante detalhado para se avaliar os Sistemas de Transcrição Automática de Laudos em Radiologia, cada vez mais presentes em hospitais e clínicas no país, além dos relatos das experiências obtidas com a aplicação desta metodologia em um caso real. / This work combines knowledge from Computer Science and Health Science in order to propose an evaluation methodology for Automatic Transcription System of Radiology Reports. At first a study regarding a Voice User Interface is presented, this interface identifies the requirements for Spoken Language Dialogue Systems and it can also be used as a tool for an evaluation methodology. Following, a study of automatic transcription systems is presented; in this study the main requirements are listed and classified. Both studies were integrated to allow a new methodology to evaluate an Automatic Transcription System in Radiology. This methodology was previously validated through some inspections and usability tests outside the hospital environment and afterword the methodology was used in a hospital in São Paulo city. As a main result it was proposed a very detailed guide for evaluating the Automatic Transcription Systems Reports in Radiology, increasingly found in hospitals and clinics in this country, apart from reports on experiences gained in applying this methodology in a real case.

How can we develop usable and work process-oriented ICT systems for shared homecare? Shared homecare involves different professionals, consists of mobile work and requires immediate and ubiquitous access to patient-oriented information, supporting an integrated view on the care process. This thesis presents a new collaborative design method for user needs analysis and requirements specification in the context of health information systems development; the Multi-disciplinary Thematic Seminar (MdTS) method. The thesis also describes the MdTS method’s application and two different usability evaluations of the developed system. The MdTS addresses a significant problem with health information technologies; they tend to support collaborative work of healthcare professionals poorly, sometimes leading to a fragmentation of workflow and disruption of healthcare processes. Based on human-computer interaction methods, MdTS implies a multiple-user needs analysis by thorough investigation of the entire interdisciplinary cooperative work and its transformation into technical specifications in order to develop appropriate information and communication technology (ICT) for the users’ differing work situations. Application of the MdTS resulted in a prototype, the OLD@HOME Virtual Health Record (VHR), adapted to the specific demands in shared homecare. Through mobile devices each care professional accessed patient information in profession-specific views from an integrated platform. This thesis provides an interesting case, illustrating how mobile ICT can support shared homecare, thereby bridging health and social care activities and improving knowledge about joint work processes. Results from the usability evaluations were overall positive. Information needed at point of care was available on mobile devices and presented in an understandable manner. However, the evaluations also indicated that it is difficult to transfer results from one homecare setting to another due to differences in operational routines. In conclusion, application of the MdTS method, in this study, succeeded in elicitation of correct user needs and in transferring correct requirements specifications to system developers for implementation.

<p>Användbarhet är en term som används för att bedöma kvaliteten hos ett gränssnitt. God användbarhet är viktig då den ger en ökad produktivitet och andra affärsfördelar i form av färre misstag och bättre kvalitet på slutprodukten. Användbarhet är en viktig designprincip men är en svår egenskap att uppfylla hos applikationer. </p><p>Studien behandlar användbarhet ur olika perspektiv, dels det teoretiska genom litteraturgenomgång, dels det praktiska genom intervjuer och observationer. Syftet var att förklara vad användbarhet är, hur det bedöms och vad man kan göra för att bygga in egenskapen i applikationer man utvecklar. För att exemplifiera och finna verklig förankring har jag valt att observera hur användare interagerar med ett existerande gränssnitt för bibliotek, Horizon. </p><p>Slutsatser kring studien är att Horizon inte används till allt den var tänkt att användas till, vilket i princip är ett dåligt betyg för en applikation. Samtidigt är detta inget större problem då den negativa verkan på verksamheten kan i det här fallet vara en definitionsfråga: är studenternas produktivitet när det gäller att söka och beställa litteratur kritisk? </p><p>När det gäller användbarhet i utvecklingsskedet kan man konstatera att även om intentionerna varit goda så har användbarhetsarbetet kring Horizon inte infriat förväntningarna. Vad som gått fel är varken sensationellt eller ovanligt; det har handlat om avsaknaden av slutanvändarens perspektiv, organisatoriska problem och möjligen också bristande kunskap om användbarhet i en eller annan form. En betydelsefull insikt som inte nämns i litteraturen men som togs upp är att beakta leverantörens marknadsställning när man ska köpa ett system. Trots bristerna, som ofta relaterar till brott mot designkonventioner, upplevs Horizon som ett bra och ändamålsenligt verktyg av sina användare. </p> / <p>Usability denotes the quality of a user interface. Even though usability is an important design principle, efforts to incorporate this quality in applications often fail. In this paper I study usability from a theoretical and a practical perspective. The goal is to explain usability and how to incorporate usability in applications. In order to exemplify, I study usability within the context of the library application Horizon. </p><p>This study shows that Horizon is only partially utilized by its users which in principle is a bad grade for an application. Partial use is however in this case, not a serious problem since the negative effects partial use imply could very well be a matter of definition: is the productivity of students, when it comes to searching and ordering library material, critical for the organization? </p><p>When it comes to usability in the development phases of a project, once again one can conclude that good intentions exist but efforts fail all the same and Horizon is no exception. This time we can attribute failure to the lack of the end users’ perspective, organizational problems and perhaps also unsufficient knowledge of usability in one form or another. An important conclusion, which has not been mentioned in the literature, is the importance of considering the market position of a presumptive vendor when buying a generic system. Despite the flaws (often related to violations of well established design principles) presented in this paper, Horizon is considered a good, effective and efficient application by its users.</p>

<p>Universal Design is a well established methodology with the fundamental purpose of designing products to be usable for as wide audience as possible, without the need of special adjustment to suit the individual. In this essay, Universal Design has had a clear influence in both the process and the result. The choice to use Universal Design as methodology in this usability evaluation, has essentiallv to do with the target audience.</p><p>As a part of the design process of MyTobii C8 has Tobii Technology ask for a usability evaluation. MyTobii C8 is an 8" touch screen computer with a windows based operating system which will initiate the software MyTobii C-Series Control. MyTobii C-Series Control is the control panel for MyTobii C8, whose interfaces constitute the platform for various modificarion of the unit. The interface of MyTobii C-Series Control is also the interface being evaluated. Because of the target audience being persons with different motoric and cognitive disabilities and theirs assistances, it is of great important that the interface is suitable for as many people as possible. With user tests, designed and analyzed with the help of Universal Design, different usability problems has been  identified and solved. Among the usability problems encountered the most vital has been the size and placement of the interactive parts and the physical interaction with the unit.</p> / <p>Universell Design är en genomarbetad metodologi, framtagen i syfte att göra produkter användbara och anpassade för så bred publik som möjligt, utan att produkten måste anpassas för individens egna förmågor.

A proposição da instância da referida abordagem a jogos digitais justifica-se a partir das particularidades contextuais desta categoria de aplicações de software, em relação a outras categorias, principalmente no que concerne à motivação de uso, sendo necessários processos de avaliação da usabilidade que considerem suas especificidades. A pesquisa também se justifica por expandir o escopo da abordagem original, considerando, além dos aspectos sintáticos, os aspectos de significado e de compreensão. A abordagem foi validada a partir de um estudo de caso, envolvendo o jogo digital Hearthstone: Heroes of Warcraft, no qual se investigou o impacto da inclusão da componente semântica ao processo de avaliação. Assim sendo, foram realizados dois experimentos, com 30 usuários cada. No primeiro grupo, considerou-se unicamente a componente sintática de avaliação, composta por: (i) avaliação heurística, (ii) mensuração do desempenho de uso e (iii) satisfação subjetiva do usuário. No segundo grupo, a componente semântica de avaliação foi incorporada à abordagem multimetodológica. O método de pesquisa foi misto, visando à coleta de dados de natureza qualitativa e quantitativa, sob uma premissa teóricopragmática. O confronto dos resultados obtidos a partir dos quatro diferentes enfoques considerados permitiu inferir impactos e contribuições positivas da integração da componente semântica à abordagem original, o que possibilita tornar mais abrangente e robusto o processo de avaliação da usabilidade da interface considerada / The purpose of this research was double fold: (i) conceiving and parameterizing a semantic approach for evaluating visual and design aspects of human-computer interfaces of digital games; (ii) integrating it into the multi-method approach conceived by Queiroz (2001). Such a research effort can be justified by the contextual particularities of this software application category with regard to other ones, mainly in what concerns use motivation and, the consequent need for a specific usability evaluation approach. The research is also justified by expanding the scope of the original approach, considering, in addition to the syntactic aspects, the aspects of meaning and understanding. The approach was validated from a case study, involving the digital game Hearthstone: Heroes of Warcraft, in which the impact of the inclusion of the semantic component on the evaluation process was investigated. Thus, two experiments were performed, with 30 users each. In the first group, only the syntactic component of evaluation was considered, consisting of: (i) heuristic evaluation, (ii) measurement of performance of use and (iii) subjective satisfaction of the user. In the second group, the semantic component of evaluation was incorporated into the multi-method approach. The research method was mixed, aiming at the collection of data of a qualitative and quantitative nature, under a theoretical-pragmatic premise. The comparison of the results obtained by the considered evaluation strategies revealed positive impacts and contributions of and including semantic aspects to the original approach. This makes it possible to enrich the usability evaluation process of a game interface, by producing complementary and more robust results.

The transformation of a manual paper-based moderation process into an electronic moderation (eModeration) process poses unique challenges. These challenges concern academic processes, people and the user experience of interactive systems. eModeration can improve the user experience of assessment processes while lowering the risk of delaying the process or losing scripts. Despite the benefits associated with optimising assessment procedures, particularly examination procedures, the use of eModeration in South Africa is limited. There are several possible reasons for a lack of eModeration adoption ranging from infrastructure and technical issues through to organisational and human factors. The focus of this study is on the human factors involved in eModeration. Since no User Experience Evaluation Framework for eModeration existed at the time of this research, an in-depth study was conducted based on the experiences of eModeration users in the context of private higher education institutions. The study focused on identifying the most important user experience constructs for the evaluation of an eModerate system within the context of private higher education institutions in South Africa towards proposing a framework. The study was based in the fields of Information Systems and Human-Computer Interaction with eModeration being the application domain. The research used a Design Science Research methodology, which involved the development and testing of a User Experience Evaluation Framework for eModeration. The data generation methods included interviews with deans, eModerators and management, as well as a survey that included responses from both moderators and deans. The research was conducted at Midrand Graduate Institute and evaluated at Monash University. The study makes a validated contribution towards identifying the most important user experience constructs. The identified constructs were utilised in the design and development of the User Experience Evaluation Framework for eModeration, which can be used along with the evaluation criteria tool to evaluate eModerate systems. / Information Science / D.

The Digital Doorway (DD) is a non-standard computer system deployed to promote computer literacy amongst the underpriviledged communities in South Africa. Since its inception there has been no usability evaluation of the software installed on the DD. This study investigate the applicability of standard involved two cycles of design research phases to develop a set of multi-category heuristics for evaluating a selection of interfaces and applications installed on the DD. The heuristic evaluation method was found to be an appropriate method for the evaluating the usability of the software as well as the direct accessibility support provided on the DD. As a triangulation exercise the heuristic evaluation was complementary role of using a combination of evaluation methods. / Computing / M. Sc. (Information Systems)

Congestion, air pollution and weather are some examples of these problems, today constantly reminded of the great damage done to citizens. The use of Information Visualization techniques can serve to support the analysis of these problems and help identify viable and effective solutions for them. On the other hand, the application of Information Visualization to the problems of urban traffic is still a poorly explored area and generally focused on simple aspects of traffic. The present thesis thus addresses the lack of studies in this area, especially in the representation of data related to origin-destination (OD) matrices. In order to do so, a specific classification is proposed for visualizations aimed at the urban traffic scenario, with the purpose of facilitating the identification of works and authors related to the area. In addition, there is the creation of new visualizations, directed to OD arrays, in order to offer different alternatives in the representation of traffic data. Finally, an approach is proposed to evaluate visualizations of OD matrices and correlated information, with the intention of offering adequate feedback to interface designers and enabling the creation of more effective visualizations. / A maioria das cidades de médio e grande porte no mundo sofre dos problemas relacionados ao crescimento do número de veículos. Congestionamentos, poluição do ar e desperdício de tempo são alguns exemplos desses problemas, hoje constantemente lembrados frente aos grandes prejuízos causados aos cidadãos. A utilização de técnicas de Visualização de Informações pode servir para apoiar a análise desses problemas e ajudar a identificar soluções viáveis e efetivas para os mesmos. Por outro lado, a aplicação de Visualização de Informações aos problemas de tráfego urbano ainda é uma área pouco explorada e geralmente focada em aspectos simples do trânsito. A presente tese vem, assim, suprir a carência por estudos nessa área, em especial na representação de dados relacionados a matrizes Origem-Destino (OD). Para tanto, propõe-se uma classificação específica para visualizações voltadas ao cenário do tráfego urbano, com o objetivo de facilitar a identificação de trabalhos e autores relacionados à área. Além disso, há a criação de novas visualizações, voltadas para matrizes ODs, com o intuito de oferecer diferentes alternativas na representação de dados do trânsito. Por fim, propõe-se uma abordagem para avaliar visualizações de matrizes OD e informações correlacionadas, com o intuito de oferecer um feedback adequado aos designers de interface e possibilitar a criação de visualizações mais efetivas.

This paper, the corresponding wireframe documentation including the functional prototype and flowchart document the evaluation and redesign of the beta version of the social networking platform ModernFamilies.net. In order to reveal possible usability flaws for people of different generations, in particular the elderly, a user-centered design approach including an expert review, diary studies and interviews were conducted. The findings reflected the need for consistency and feedback in general. For young children, the concept of the site appeared to behard to grasp. Experienced users found the access and management of relatives cumbersome. Most importantly, the elderly, novice computer users had a hard time getting started with the site on their own because they did not have access to a PC nor internet at their home. The latter and the fact, that some issues might never be solved by traditional usability testing because the user just feels overwhelmed by the vast amount of communication features he is faced with today calls for alternative, more intelligent, ambient interfaces. However, we came to the conclusion that although evaluation of such new technologies with elderly people is not alwayseasy, it is best to be conducted in the participants home or a similar environment. / AGNES
