Ce projet de recherche vise à explorer le rôle du design dans l’acte d’achat et l’évaluation des produits. L’hypothèse de recherche repose sur le fait que le design est un obstacle à la rationalité dans le choix d’un bien, car ce dernier est rattaché à des singularités qui lui sont propres, le rendant difficilement comparable aux autres biens d’un même marché. Les produits deviennent difficiles à évaluer et à classer parmi les autres biens similaires dans le marché. En soi, la finalité et les vertus du design permettent aux consommateurs d’avoir une plus grande liberté de choix, mais ce rôle dynamique et économique que peut prendre le design peut aussi confondre les consommateurs devenant brouillés par l’abondance de choix. En ce sens, le design serait la clé de la voûte d’une économie des singularités telle que proposée par Lucien Karpik dans L’économie des singularités. Avec une méthodologie ethnologique, cinq projets d’évaluation de produits au sein de deux organismes produisant des dispositifs d’aide à la consommation ont été observés sur une période de deux ans. À la conclusion de cette étude, il a été démontré que certaines améliorations pouvaient être apportées aux processus d’évaluation, plus particulièrement en ce qui concerne les facteurs qui ne sont pas pris en compte dans les dispositifs d’aide à la consommation actuels, comme l’évaluation de produits centrée sur l’usager à l’aide de scénarios d’usages, plutôt que l’évaluation de produits centrée sur l’objet, ainsi que la considération de l’expérience de l’usager dans l’évaluation des biens. / This research project aims at exploring the role of design within the act of purchasing and rating products. This premise is based on the fact that design is an obstacle to an individual’s rationality when choosing goods because they are multidimensional and of uncertain quality, as proposed by Lucien Karpik. This creates a difficulty faced by consumers when trying to find comparable products on the market. The research hypothesis of this project suggests that design is an obstacle to reason by offering multidimensional products to consumers. It then becomes harder for them to evaluate singular products available on the market, and to make wise consumption choices. One of the aims of design is to offer users freedom of choice, but this dynamic and economic role of design can also lead to confusion, where consumers become blinded by the abundance of choices. In this sense, design would be the keystone of a singularity-based economy. Five product rating projects were observed on a two-year period within two agencies involved in producing consumption aid devices by using an ethnological approach. The conclusion of this study has shown that some improvements could be made to the product rating processes, particularly for the facts that have not been accounted for in the actual consumption aid devices, such as user-centered product ratings based on user scenarios instead of object-centered product ratings, as well as considering user experience in product evaluation.

Les défis associés au phénomène du vieillissement démographique de la population se manifestent sous plusieurs formes et à de nombreux égards. Il y a des questions générales comme celles qui touchent l’économique et d’autres, plus spécifiques et situées, comme celles des modalités assurant des services et des soins adéquats aux personnes vulnérables. Par exemple, le colloque « La qualité de l’expérience des usagers et des proches : vers la personnalisation des soins et des services sociaux », programmé dans le cadre des Entretiens Jacques Cartier à l’automne 2014, s’était donné comme objectif d’examiner l’expérience personnelle des usagers relativement aux prestations de soins de santé et à l’organisation des services sociaux. L’origine de ces réflexions réside dans la nécessité de trouver un meilleur équilibre des pouvoirs dans les relations d’aide ou la prestation de soin. Cette problématique sous-entend l’idée de rendre les usagers capables d’un certain contrôle par l’adoption d’approches permettant aux professionnels de faire des ajustements personnalisés. Cette thèse de doctorat s’inscrit directement dans le prolongement de cette problématique. La recherche vise à examiner les conditions en mesure de rendre possible, dans les Centres d’hébergement et de soins de longue durée (CHSLD), un rapport au monde catégorisé par ce que le sociologue Laurent Thévenot nomme le régime de la familiarité. Le régime de la familiarité fait référence aux réalités où l’engagement des personnes se déploie dans l’aisance. Autrement dit, ce régime d’engagement correspond à un rapport au milieu où la personne est en mesure de déployer ses habitudes, d’habiter le moment et de se sentir chez elle. Comme le montre Thévenot, ce type d’engagement commande la conception d’un monde qui offre aux personnes la possibilité d’articuler les modalités de leurs actions sur des repères qui font sens personnellement pour eux. Ainsi, l’objet de la recherche consiste à mieux comprendre la participation du design à la conception d’un milieu d’hébergement capable d’accueillir ce type d’engagement pragmatique. Les orientations associées à la conception de milieux d’hébergement capables de satisfaire de telles exigences correspondent largement aux ambitions qui accompagnent le développement des approches du design centrées sur l’usager, du design d’expériences et plus récemment du design empathique. Cela dit, malgré les efforts investis en ce sens, les capacités d’appropriation des usagers restent un problème pour lequel les réponses sont précaires. La thèse interroge ainsi le fait que les développements des approches de design, qui ont fait de l’expérience des usagers une préoccupation de premier plan, sont trop souvent restreints par des questions de méthodes et de procédures. Le développement de ces connaissances se serait fait au détriment de l’examen précis des savoir-être également nécessaires pour rendre les designers capables de prendre au sérieux les enjeux associés aux aspirations de ces approches. Plus spécifiquement, la recherche précise les qualités de l’expérience des établissements dont le design permet l’engagement en familiarité. L’enquête s’appuie sur une analyse des jugements posés par des équipes d’évaluation de la qualité du milieu de vie des CHSLD présents sur le territoire Montréalais. L’analyse a mené à la caractérisation de cinq qualités : l’accueillance, la convivialité, la flexibilité, la prévenance et la stabilité. Finalement, sous la forme d’un essai réflexif, un tableau de savoir-être est suggéré comme manière de rendre les designers capables de mettre en œuvre des milieux d’hébergement présentant les qualités identifiées. Cet essai est également l’occasion du développement d’un outil réflexif pour une pédagogie et une pratique vertueuse du design. / The phenomenon of an aging population brings with it a whole host of diverse challenges. Some of these challenges are of a general nature, such as those related to economics, while others are much more specific, such as the conditions and procedures needed to ensure that vulnerable individuals receive adequate care and services. For instance, a symposium entitled “Providing a quality experience for users and loved ones: personalization of care and social services,” held during the fall 2014 Entretiens Jacques-Cartier, aimed to examine personal user experiences pertaining to the delivery of health care services and the organization of social services. This meeting’s initial hypothesis underscored the need for a more balanced power dynamic with caregivers or in the delivery of care. This hypothesis is based on the concept of user capabilities, achieved through the adoption of practices which enable professionals to provide personalized care. Further exploration of this particular issue is at the core of this doctoral thesis. This research aims to examine the conditions which would allow people living in long-term care facilities to engage with their environment in a way the sociologist Laurent Thévenot categorized as “familiar engagement.” Familiar engagement refers to realities in which people are able to rest on an accustomed dependency with the things and people that surround them. In other words, this type of engagement refers to a relationship with one’s environment which allows individuals to take part in their usual habits, and where they feel at home and at ease in their surroundings. As Thévenot’s analysis shows, this type of engagement requires the conception of a world which allows people to frame their actions around reference points which are personally relevant to them. Thus, this research aims to better understand the role of designers in the conception of nursing homes where this type of pragmatic engagement is made possible. The guidelines for the development of residential facilities able to satisfy these criteria are largely in line with the expectations surrounding the development of user-centered design, experience design, and empathic design. That being said, despite the efforts put forth towards this initiative, self-identification with one’s environment remains an unresolved problem. Our hypothesis is that the evolution of user-centered design is too often restricted by methodological or procedural issues. Development in this direction has been done to the detriment of the precise examination of the virtues needed by designers in order to be able to seriously take on the issues associated with the goals of this design approach. More specifically, this research identifies the qualities of long-term care facilities’ experience whose design allows for familiar engagement. For our study, we analyzed the findings and judgments of living environment evaluation teams concerning the quality of living environments of the long-term care facilities in the Montreal area. Through this survey, five qualities have been identified: welcomeness, conviviality, flexibility, thoughtfulness and stability. Finally, as a reflective essay, a portrait of virtues is suggested as a way for designers to implement facilities that share those qualities. The dissertation also presented a reflexive tool for a virtuous design practice and pedagogy.

A modalidade de Educação a Distância (EAD) ocupa atualmente um lugar importante no desenvolvimento e expansão da Educação no Brasil. A EAD a partir de novas tecnologias, teve um grande impulso, principalmente aquela que envolve a rede Internet. O uso das tecnologias digitais em espaços educativos permitiu que a comunicação, interação, armazenamento e distribuição de conteúdos para o processo educativo, fossem realizados de maneira mais eficiente.

Esta dissertação de mestrado fez parte do projeto Qualipso (Quality Platform for Open Source Software) que teve como principal objetivo melhorar a confiabilidade de sistemas de software livre. Nesse contexto, o enfoque desta pesquisa é um dos atributos de qualidade de software: usabilidade. As práticas de usabilidade no desenvolvimento de software livre, são aplicadas na maioria das vezes, em projetos patrocinados por grandes empresas ou que possuam especialistas em usabilidade como membros da equipe. Mas, em projetos menores da comunidade, compostos geralmente por desenvolvedores, raramente ela é considerada. Porém, a usabilidade é um atributo fundamental para a qualidade durante o uso de um sistema. Com base em valores compartilhados entre as comunidades de métodos ágeis e de software livre, esta dissertação propõe a adaptação de práticas de usabilidade no contexto de métodos ágeis para o contexto de comunidades de software livre. Por meio de pesquisa bibliográfica, levantamos as principais práticas de usabilidade tanto no âmbito de métodos ágeis, quanto no âmbito de software livre, e as classificamos de acordo com as fases do Design Centrado em Usuário, descrevendo cada uma com o formato nome-contexto-problema-solução-exemplos. As práticas foram exploradas em projetos de software livre, o que possibilitou maior entendimento de problemas enfrentados em contextos reais. Essa experiência resultou na proposta de adaptação de práticas de usabilidade ágil no contexto de comunidades de software livre. Dessa forma, descrevemos a realização de uma pesquisa-ação no projeto Arquigrafia-Brasil, um estudo de caso no projeto Mezuro e a aplicação de práticas de usabilidade em quatro projetos do Centro de Competência em Software Livre do IME-USP. / This Masters thesis was part of the Qualipso project (Quality Platform for Open Source Software) whose main objective was to improve the reliability of free and open source software systems. Within such context, the focus of this research is one of the attributes of software quality: usability. The usability practices in free and open source software development are applied most often in projects sponsored by large companies or employing usability experts as team members. But on smaller projects in the community, generally composed by developers, it is rarely considered. However, usability is an essential attribute to the quality in use of a system. Based on values shared between the communities of agile methods and free and open source software, this thesis proposes the adaptation of usability practices in the context of agile methods to the context of free and open source software communities. Through the study of the literature in the field, we gathered the main usability practices both within agile methods, as in free and open source software, and we classified according to User-Centered Design phases, describing each one with the format name-context-problem-solution-examples. The practices were explored in free and open source software projects, which enabled greater understanding of problems faced in real contexts. This experience resulted in the adaptation proposal of agile usability practices into the context of free and open source software communities. We describe the implementation of an action research in the Arquigrafia-Brazil project, a case study in the Mezuro project and the application of usability practices in four projects of the IME-USP FLOSS Competence Center.

This PHD is about design as a tool of interaction based in information systems, allowing not only to understand the relationship of design with the user, as also, based on User Centered Design, to create a methodology that solves real problems derived from its personal needs. In the case study, the work was based on People with Special Needs, which by their limitations spend much of their day sitting and consequently end up suffering from pressure ulcers. From the research methodology resulted an approach that in a first stage relates psychophysical data acquisition and processing derived from information systems, in an approximation to semiotics. In a second stage an application has been developed in LabView for the integration and processing of data relating to acquisition of user data and data regarding the characteristics of materials and prototyping processes. The result is a file that can be interpreted by CAD systems. The third and final phase, based on the interpretation of the data in the CAD system, allows exporting the information to a CAM system and consequently the production of a customized product through rapid manufacturing technology. The work developed resulted in an integrated system called "Core System" divided by modules that allows management of all information in real time regardless of the inputs of each of its sub-modules, allowing each of these changes to be reflected in the final result. The application is the result of research work that relates the different multidisciplinary areas, building, based on correlations and data validation by specialized technicians, information processing models. / Este trabajo aborda el papel como herramienta de interacción basada en los sistemas de información permitiendo no sólo entender mejor la relación del diseño con el usuario y, basándose en el Diseño Centrado en el Usuario, crear una metodología que solucionase problemas reales resultado de una necesidad personal. En el caso de estudio el trabajo se basó en personas con necesidades especiales, que por sus limitaciones pasan gran parte del día sentados, y por eso con el tiempo sufren de úlceras por presión. De la metodología de investigación resultó un enfoque que en una primera etapa relaciona la adquisición y procesamiento de datos psicofísicos en una aproximación a la semiótica partiendo de sistemas de información.

Usability is one of the quality attributes, and is related to making the experience enjoyable user through an efficient and intuitive interface design. Agile methods are committed to deliver valuable software to the satisfaction of the customer. At times, they deliver only the utility, without covering aspects of usability. Design solutions providing greater usability and more appropriate to the users’ context is the main concern of the Interaction Design (IxD). The IxD is based on user-centered design, which takes into account the users needs and wants, aiming to promote interaction more enjoyable experience. In recent years, the attention in integrating user-centered design practices into agile methodologies has increased. However, a very limited number of contributions have addressed the integration into a broader level, gathering practices and providing guidance to the organization of work within a software development roadmap. This dissertation presents an approach to integrate user interaction design into Scrum process through activities and artifacts. In the first stage of the study, a literature study was performed to determine possible strategies for integrating IxD into Scrum process. Furthermore, an action research approach was applied to define and evaluate the artifacts that would support the ScrumUX integration approach, closely with the professionals in the software development industry. In the second stage, an experimental study was carried out to evaluate the proposed ScrumUX integration compared to traditional Scrum approach. The experiment was carried out in an academic context, in which nineteen students divided into five teams worked in software development projects, in the ERP systems domain. Statistical tests confirmed a significant difference between the experimental and control groups, noting that the teams who used the ScrumUX approach produced software with better degree of usability in the task support perspective, considering ERP systems’ users opinion. / Princípios do desenvolvimento ágil asseguram que a atenção contínua á excelência técnica aliada á um bom design contribui para o aumento de agilidade garantindo produtos com maior qualidade. A usabilidade é um dos atributos da qualidade, e está relacionada com tornar a experiência do usuário agradável por meio de um design de interface eficiente e intuitivo. Métodos ágeis estão comprometidos em satisfazer os clientes entregando software de valor. Mas, por vezes, acabam entregando somente a utilidade, sem cobrir os aspectos de usabilidade. Projetar soluções com maior usabilidade e mais apropriadas ao contexto dos usuários é a principal preocupação do Design de Interação (DxI). O DxI fundamenta-se no design centrado no usuário, que leva em conta as necessidades e desejos dos usuários para promover a mais agradável experiência de interação. O interesse em integrar práticas de design centrado no usuário com metodologias ágeis tem aumentado nos últimos anos. Contudo, um número bem limitado de contribuições têm abordado a integração em um nível mais abrangente, reunindo práticas e fornecendo orientações para a organização do trabalho dentro de um roteiro de desenvolvimento de software. Esta dissertação apresenta uma abordagem para integrar o Design de Interação do usuário ao processo Scrum por meio de atividades e artefatos. Na primeira etapa do estudo, realizou-se um estudo bibliográfico para verificar as possíveis estratégias para a integração do DxI com o processo Scrum, e em paralelo uma abordagem de pesquisa-ação foi aplicada, junto á profissionais da indústria de desenvolvimento de software, para definir e avaliar os artefatos que dariam suporte á abordagem de integração ScrumUX. Na segunda etapa, um estudo experimental foi conduzido com objetivo de avaliar a proposta de integração ScrumUX em relação ao Scrum tradicional. O experimento foi realizado em contexto acadêmico, onde dezenove alunos divididos em cinco equipes atuaram em projetos de desenvolvimento de software no domínio de sistemas ERP. Os testes estatísticos confirmaram uma diferença significativa entre os grupos experimentais e de controle, apontando que as equipes que utilizaram a abordagem ScrumUX produziram softwares com melhor grau de usabilidade na perspectiva de suporte á tarefas, considerando o ponto de vista de usuários de sistemas ERP.

First-class software engineering is no longer enough for an information system product to gain success on a market. Developing successful information system products has become a challenging practice that requires an understanding of those who are going to use the products. As product innovation has become the lifeblood of companies competing in the fast- paced IT industry, the end users have ultimately become those who determine the success of these type of products. User research is conducted to gather insights of users’ contexts, behaviors and feelings when using products. It can be practiced to explore how to create products and features that end users will find useful. This thesis examines how methods and tools used in user research can expose opportunities for innovation. The study was conducted by a literature study and a case study, where user research methods were put to practice to discover opportunities for creating a concept for a new product. Emphasis was also put on studying how to provide utility when developing a new product. The case study was performed over a four month period at an e- commerce company called Swiss Clinic in Stockholm, Sweden. The study shows that opportunities for innovation in user research occur in the interplay between business, user research discoveries and iterative design and that effective communication and artifacts play essential parts for innovating successfully.
