Connaître la géographie de son environnement urbain est un enjeu important pour les personnes déficientes visuelles. Des cartes tactiles en relief sont généralement utilisées mais elles présentent des limitations importantes (nombre limité d'informations, recours à une légende braille). Les nouvelles technologies permettent d'envisager des solutions innovantes. Nous avons conçu et développé une carte interactive accessible, en suivant un processus de conception participative. Cette carte est basée sur un dispositif multi-touch, une carte tactile en relief et une sortie sonore. Ce dispositif permet au sujet de recueillir des informations en double-cliquant sur certains objets de la carte. Nous avons démontré expérimentalement que ce prototype était plus efficace et plus satisfaisant pour des utilisateurs déficients visuels qu'une carte tactile simple. Nous avons également exploré et testé différents types d'interactions avancées accessibles pour explorer la carte. Cette thèse démontre l'importance des cartes tactiles interactives pour les déficients visuels et leur cognition spatiale.

Achieving product and process quality are among the central themes of software engineering, and quality is an important factor in the marketplace. Usability and user experience (UX) are two important aspects of quality, particularly for interactive products. To achieve usability means producing products that let users do things in a satisfactory, efficient and effective way. To develop products with good UX, means going beyond usability, in ways that are still not clear to us. Achieving good usability and UX is hard. This thesis is concerned with organizations which work towards these goals. This research is concerned with understanding and improving the processes by which technology is designed and developed, and understanding the demands and expectations users have. It is about how companies can and actually develop products with good usability and UX, and what stops them from working towards this as efficiently as they could. We have viewed the usability and UX challenge from the viewpoints of Quality, Organizations, and Institutions, with a focus on participatory design, user-centred design and wicked problems. The research can be characterised as empirical research performed over a period of seven years, in close cooperation with industrial partners. The research was performed using multiple data collection methods to create constructs and shape theory. The field methods have ranged from being a participant observer, to performing interviews and holding workshops with members of the participating organisations. A case study approach was initially used, but focus soon moved from case study methodology to a closer focus on grounded theory, and finally the focus shifted to constructivist grounded theory. The thesis contributes to the field of software engineering in several ways. Usability has a long history within software engineering, human computer interaction, and design science, but the different discourses within the fields have meant that communication between the fields was problematic. The research in this thesis has moved between the different fields, contributing to bridging the gap between the areas. It gives an illustration of how usability work actually takes place in different types of companies, from a developer of operating systems for smartphones, to a global engineering company, which knows that it must find ways of working with, and measuring, usability and user experience. It gives concrete knowledge about the way in which companies can work with usability testing, and how they can provide information to satisfy the information needs of different stakeholders. It provides a discussion of the state of UX today, taking up the problems that stop industry making use of the definitions and theories of UX that exist. Thus, it gives an illustration of the different factors in product design, development and sales, from dealing with organizational factors to satisfying user needs, that all make usability work such a rocky road to navigate.

Cette thèse porte sur la conception d’interfaces de papier interactif dédiées à la création musicale. Malgré l’apparition d’outils informatique permettant de créer de nouveaux sons ou d’opérer des transformations sur des représentations symboliques de la musique, les compositeurs utilisent toujours le papier pour composer. Le papier interactif rend théoriquement possible la création d’interfaces combinant l’expression sur le papier et la puissance de calcul de l’ordinateur. Cependant, la conception de telles interfaces reste un problème complexe car chaque compositeur développe son propre processus de création, impliquant de nouveaux concepts et de nouvelles représentations musicales. Cette thèse propose l’utilisation de structures personnelles et adaptables sur le papier pour permettre aux compositeurs d’exprimer et d’explorer leurs idées musicales. Trois études conduites avec des compositeurs à l’Ircam (Chapitre 3) s’intéressent aux rôles du papier et de l’ordinateur lors du processus de composition et les possibilités du papier interactif pour l’exploration des idées entre ces deux supports. Je décris des sessions de conception participative (Chapitre 4) qui examinent l’utilisation de représentations musicales formelles pour la création de nouvelles interfaces de papier couplées avec les logiciels de composition assistée par ordinateur. Je présente les Paper Substrates (Chapitre 5), des composants papier qui définissent des structures modulaires pour l’interaction avec des représentations personnelles de données musicales issues d’environnements informatique. Je décris une boîte à outil ainsi qu’une application graphique permettant de développer des interfaces utilisant les Paper Substrates. Des exemples illustrent la création de structures personnelles et de données musicales sur le papier qui peuvent être interprétées par les logiciels de composition assistée par ordinateur. Je présente une étude d’observation structurée conduite avec 12 compositeurs utilisant Polyphony pour composer une pièce électroacoustique (Chapitre 6). Polyphony est une interface qui intègre le papier interactif avec d’autres interfaces pour composer. L’étude a per- mis d’observer et de comparer les différents processus de composition des participants. Enfin, je détaille un projet de recherche et création mené avec le compositeur Philippe Leroux pour la création de sa pièce Quid sit musicus (Chapitre 7). Nous avons conçu de nouveaux systèmes interactifs pour la création de ressource compositionnelles, la synthèse sonore et le contrôle de la spatialisation à partir de tracés effectués sur une partition médiévale. / This thesis focuses on the design of interactive paper interfaces for supporting musical creation. Music composition has been deeply influenced by the computational power brought by computers but despite the use of software to create new sounds or work with symbolic notation, composers still use paper in their creative process. Interactive paper creates new opportunities for combining expression on paper and computation. However, designing for highly individual creative practitioners who use personal musical representations is challenging. In this thesis, I argue that composers need personal and adaptable structures on paper in which they can express and explore musical ideas. I first present three field studies (Chapter 3) with contemporary composers that examined the use of paper and the computer during the composition process and how linking the two media supports exploration of musical ideas. I then describe a participatory design study that investigates the use of formal musical representations (Chapter 4) for creating new paper interfaces that extend computer-aided composition tools. I introduce Paper Substrates (Chapter 5), interactive paper components that provide modular structures for interacting with personal representations of computer-based musical data. I detail tools that we created to develop paper applications with the Paper Substrates approach. Several examples illustrate the creation of personal structures and musical content that can still be interpreted by computer-aided composition software. I then describe a structured observation study with 12 composers who used Polyphony to compose a short electroacoustic piece (Chapter 6). Polyphony is a unified user interface that integrates interactive paper and electronic user interfaces for composing music. The study allowed us to systematically observe and compare their compositional processes. Finally, I report on a research and creation project with the composer Philippe Leroux during the composition of his piece Quid sit musicus (Chapter 7). Several work sessions with the composer and a musical assistant lead to the design of new paper- based interfaces for generating composition material, synthesizing sounds and controlling the spatialization from handwritten gestures from calligraphic gestures over an old manuscript.

Over the history of interaction design, concepts and methods of prototyping have been significantly developed to address new challenges faced by the field and the ever-going advancement of new technologies. Some of the important developments are related to the notions of mixed-fidelity prototyping, experience prototyping, and prototypes as filters. Building upon these developments, this study explores a multiple-fidelity prototyping approach, that is, using progressively higher fidelity prototypes in iteration. The study focused particularly on the design of user engagement. It documented, and contributed to, an actual design process of Xplore, an augmented reality game-based learning application. Three participatory design-style workshops employing low-, mixed-, and high-fidelity prototypes were conducted respectively. Thematic analyses of participants’ interactions revealed sets of themes in the workshops, which reflected the changing focus and scope of the design space. The implications of the results obtained in the study highlighted the role of prototypes of each fidelity level in engaging users in a design process, as well as the potential benefits of combining multiple fidelity prototypes when designing for user engagement.

L'intensification et l'homogénéisation des paysages agricoles a rendu les agrosystèmes plus sensibles aux bioagresseurs. Pour limiter les impacts de ces bioagresseurs sans recourir de manière intensive aux pesticides, une solution efficace est l'utilisation de variétés résistantes. La durabilité de ces résistances peut être faible, en lien avec l'adaptation des populations pathogènes. Il est donc nécessaire de concevoir des systèmes de culture permettant le contrôle des bioagresseurs et la préservation des ressources variétales. Ces stratégies de gestion peuvent reposer sur la combinaison de pratiques agricoles et d'organisation spatiale de ces pratiques, pour des pathosystèmes dont les agents sont dispersés par le vent. D'une part, la conception de ces stratégies peut bénéficier d'une approche participative, prenant en compte les conditions de culture et l'organisation des acteurs locaux. D'autre part, l'évaluation de ces stratégies, dont l'expérimentation est délicate du fait des échelles spatiale et temporelle requises, peut bénéficier d'une approche modélisatrice. Dans ce cadre, ce travail de thèse a mis au point et testé, sur deux régions d'étude, une méthode participative de construction de scénarios d'organisation spatiale des systèmes de culture, évalués vis-à-vis du contrôle du phoma du colza et de la gestion des résistances. Les scénarios co-construits explorent les futurs agricoles possibles en identifiant les tendances possibles d'évolution du contexte (économique, politique, règlementaire, épidémique), de manière prédictive ou plus exploratoire. Ils ont ensuite été évalués numériquement à l'aide d'un modèle préexistant, vis-à-vis de trois critères pertinents pour les acteurs : les pertes de rendement, la taille de la population pathogène et sa structure. Ces scénarios ont ensuite été évalués à l'aide de régressions linéaires, de manière à identifier les pratiques agricoles les plus influentes sur les trois critères d'évaluation considérés. Cette analyse a été réalisée à deux échelles spatiales complémentaires : l'échelle d'une petite région agricole et l'échelle locale, considérant plusieurs centaines de mètres autour des parcelles de colza pouvant être infectées. Ces analyses ont permis de mettre en évidence la prépondérance des rotations, des variétés et de la gestion des résidus de colza dans l'évolution de la maladie et sur la durabilité des résistances. Elles ont également montré la nécessité de prendre en compte plusieurs échelles pour la gestion de la maladie : si la taille de la population pathogène et les pertes de rendement peuvent être déterminées à partir de la composition en termes de systèmes de culture à l'échelle du paysage, une échelle plus locale est nécessaire pour évaluer l'évolution de la structure génétique de la population. Cet indicateur est en effet très lié aux variétés et aux pratiques présentes dans les 500 mètres autour des parcelles porteuses de la résistance considérée. Finalement, l'exploration de règles spatiales (isolement) et temporelles (maximisation des surfaces un an sur deux) des parcelles de colza ou des types variétaux a mis en exergue le fort potentiel de stratégies basées sur ces règles pour la gestion des résistances. La mise en place de ces stratégies nécessiterait une coordination entre les différents acteurs, à l'échelle du territoire agricole, qui pourrait s'avérer nécessaire en cas d'épidémie importante de phoma. La méthode mise en place pourrait être utilisée pour explorer la gestion d'autres thématiques à composante spatiale, comme par exemple l'érosion ou la gestion d'autres bioagresseurs. Ceci pourrait permettre une évaluation multicritère, prenant par exemple en compte les bioagresseurs de différentes cultures composant une même rotation, identifiant ainsi les pratiques les plus à mêmes de gérer simultanément les différentes thématiques locales. / The intensification and the homogenization of agricultural systems led to agrosystèmes that are more sensible to pests and diseases. To limit the impacts of these pests and diseases without increasing pesticides use, an efficient solution is the use of resistant cultivars. Sustainability of these resistances can be low, in link with the adaptation of pathogen populations. It is thus necessary to design cropping systems allowing both the control of pests and diseases and preservation of cultivar resistances. Such management strategies can combine cropping practices and their spatial organization, for pathosystems whose agents are wind-dispersed. The design of these strategies can benefit from participatory approaches, taking into account the local cropping systems and stakeholders' organizations. The evaluation of these strategies, hardly testable in reality due to the spatial and temporal scales involved, can benefit from a modeling approach. Within this scope, this PhD thesis designed and tested, in two study regions, a participatory method of scenarios design, aiming at building with local stakeholders scenarios of spatial organization of cropping systems and to assess them with regards to their performances on phoma stem canker of winter oilseed rape and resistance durability management. Participatory designed scenarios explore agricultural futures that may happen by identifying the possible evolutions of the context (economic, political, regulatory or epidemic), in a predictive or more exploratory way. Scenarios are then evaluated numerically with a pre-existing model, for three criteria relevant for the stakeholders: yield losses, structure and size of the pathogen population. This analysis has been performed at two complementary spatial scales: the regional and the local scale, considering hundreds of meters around fields cropped with sensitive cultivars. These analyses showed the importance of crop rotations, cultivars and tillage for the evolution of the disease and resistance sustainability. These analyses also showed the necessity of taking into account different scales for disease management. Indeed, size of the pathogen population and yield losses are well related to the landscape composition in terms of cropping practices, but a more local scale is necessary for the assessment of the genetic structure of the pathogen population. This indicator is thus significantly linked with the cultivars and cropping practices in the 500 meters around fields cropped with the considered resistance. Finally, we explored spatial (isolation) and temporal rules for rapeseed spatial and temporal allocations that could be used to manage resistance. For these strategies to be applied, coordination between stakeholders at the agricultural territory would be necessary, which could be necessary in case of strong phoma stem canker epidemics. The method we applied could be used to explore other thematic with a spatial component, as for instance pests or erosion. This could allow a multi-criteria analysis, for instance taking into account pathogens of different crops included in a rotation, thus identifying the cropping practices that could promote management of these local problems.

Att besöka museum är ett populärt nöje, och ett sätt att erhålla ny kunskap. Tidigare studier har visat på positiva resultat av att öka meningsfullheten av besöken genom användning av teknologi. Denna forskning introducerade en design som framtagits genom deltagande design. Forskningen visar på möjligheten att förstärka upplevelsen av museibesöket genom digitalt gåvo-givande beteende. Deltagarna besöker ett museum som ett par, där den ena parten agerar gåvogivare och den andra mottagare. Under besöket ritar deltagarna sketcher, hittar objekt, svarar på frågor angående utställningsföremålen och samlar därigenom ledtrådar för att avkryptera gåvan. Denna forskning förklarar hur gåvo-givande beteende bidrar till den sociala upplevelsen mellan romantiska par och hur denna bidrar till upplevelsen av museibesöket. Resultatet erbjuder möjligheter för vidare forskning om hur nära förhållanden påverkar meningsfulla upplevelser. / Museums are popular among people to relax and obtain knowledge. Prior studies showed great efforts on increasing meaningfulness of the museum tour with the support of technology. This research introduces a design created through participatory design practice. The interaction presents its potential of enhancing the museum visiting experience for visitors in intimate relationships through digital gift- giving behavior. Participants visit the museum as couples, with one party acting as the gift giver and the other as the gift receiver. During the visit, participants draw sketches, find objects, answer questions related to the objects and collect the clues to decrypt the given gift. This research explains how gift- giving behavior enhances the social experience between the intimate couple and how social interaction between intimate couple enhances the museum visiting experience. This research suggests the opportunity for research on the effect of the close relationship on meaningful experiences.

Esta dissertação trata de questões relativas à experimentação prática no processo de ensino-aprendizagem nos cursos de arquitetura e urbanismo. Com a perspectiva de contribuir com o ensino de arquitetura no Brasil, foram escolhidas para análise duas realidades: a Universidade de São Paulo, no Brasil, com foco nas disciplinas da FAUUSP em que há o desenvolvimento do espaço pedagógico do Canteiro Experimental; e nos Estados Unidos, em comunidades pobres do Alabama, com base no método de trabalho do Rural Studio, da Universidade de Auburn. O Canteiro Experimental da FAUUSP é um equipamento pedagógico e uma proposta metodológica de ensino desenvolvido nos últimos quinze anos, dentro das atividades curriculares práticas construtivas com os alunos. O Rural Studio é um projeto pedagógico formado por estudantes e professores, com metodologia de trabalho de um laboratório de ensino e extensão, que desenvolve com a comunidade beneficiada projetos e depois construções de casas e espaços coletivos para assentamentos pobres do sul dos Estados Unidos. O trabalho analisa a influência desses processos educativos na formação de um arquiteto com prática profissional direcionada à população atualmente desatendida, considerando a importância fundamental da educação na promoção de transformações sociais. Para isso, a pesquisa abordará em um primeiro momento a relação da evolução dos movimentos de moradia, das políticas públicas habitacionais no Brasil e as teorias do grupo \"Arquitetura Nova\" com as iniciativas decorrentes nas Escolas de Arquitetura como os Laboratórios de Habitação e Canteiros Experimentais. Em seguida, analisará o Canteiro Experimental da FAUUSP, procurando entender como este espaço de práticas construtivas pode ser estendido a atividades dentro de comunidades. Para, enfim, fazer uma análise do grupo americano e compreender as possíveis contribuições que podem ser incorporadas à realidade brasileira. Ao resgatar experiências inovadoras, o presente projeto visa ainda contribuir para uma necessária renovação do ensino de arquitetura no Brasil, aproximando a teoria da prática construtiva e a Universidade da comunidade. / This dissertation deals with issues of practical experimentation in the process of teaching-learning courses in architecture and urbanism. With the prospect of contributing to the teaching of architecture in Brazil, two realities were selected for analysis: the University of São Paulo, in Brazil , focusing on the disciplines of FAUUSP where the is the development of the pedagogical space at the Experimental Job Site; and the United States, in poor communities in Alabama, based on the method of work of the Rural Studio, of the Auburn University. Experimental Job Site of FAU is a teaching equipment and methodology developed in the last fifteen years within the construction practices curricular activities of students. The Rural Studio is a pedagogical project formed by students and teachers, with methodology of a laboratory for teaching and extension, which develops with the benefiting community projects and then constructs houses and collective spaces for poor settlements of the southern United States. The paper analyzes the influence of these educational processes in the formation of an architect with professional practice directed to the currently underserved population, considering the fundamental importance of education in promoting social change. Therefore, the research will focus at first on the relationship of the development of housing movements, of public housing policies in Brazil and the theories of the group \"New Architecture\" with initiatives arising in the Schools of Architecture as the Housing Laboratories and Experimental Job Site. Then examines the Experimental Job Site of FAU, trying to understand how this space of construction practices can be extended to activities within communities. To finally make an analysis of the American group and understand the possible contributions that can be incorporated to the Brazilian reality. By rescuing innovative experiences, this project aims to contribute to a necessary renewal of architectural education in Brazil, bringing the theory of constructive practice and the University of the community.

Grande parte das moradias brasileiras apresenta coberturas inadequadas, conforme indicação de pesquisa sobre o deficit habitacional. A carpintaria dessas coberturas necessita de mão de obra qualificada e materiais de custos elevados, porém, na maioria dos casos ainda hoje utiliza processo construtivo artesanal. O objetivo deste trabalho é identificar quais as condições necessárias para viabilizar a produção de sistemas de cobertura adotando o processo de préfabricação com madeiras de florestas plantadas, em contextos com precariedades, como nos casos dos assentamentos rurais. Os estudos se concentraram em dois assentamentos rurais; no primeiro, Assentamento Rural Pirituba II no município de Itapeva - SP, foi desenvolvido o sistema de cobertura VLP (vigas laminadas pregadas) e empregado em 35 moradias; no segundo, Assentamento Rural Sepé Tiaraju localizado no município de Serra Azul - SP, foi desenvolvido o sistema de cobertura Painéis pré-fabricados e empregado em 67 moradias. A estratégia adotada para a coleta de dados do produto e do processo aconteceu ao longo da cadeia de produção dos sistemas de cobertura, começando pelo desenvolvimento do projeto, passando pela realidade social do assentamento até a aplicação das propostas em cada assentamento. O desenvolvimento e escolha da proposta elaborada utilizam o processo participativo com envolvimento direto das famílias em todo o processo. Os resultados obtidos permitem concluir que ambos os sistemas de cobertura pré-fabricados atendem às condições necessárias na redução de custos com materais e mão de obra melhorando a qualidade de acabamento dos sistemas de cobertura mesmo trabalhando em situações com precariedade de infraestrutura. A relevância da pesquisa está no fato de agregar valores não comuns às coberturas das habitações rurais possibilitando a replicação dos princípios adotados em situações semelhantes, mesmo que em contextos diferentes, demonstrando que a pré-fabricação com o processo participativo podem ser alternativas viáveis para comunidades organizadas. / There are many Brazilian houses with inadequate roofs, as indicated by research on the housing deficit. The traditional build-up roofs require skilled labor and expensive materials, made in a handmade construction process. The objective of this research is to identify the necessary conditions to enable the production of roof systems by adopting the pre-fabrication with soft-wood from reforestations, to be applied in precarious situations, such as are found in rural settlements. The studies focused on two rural settlements. At the first, in the Pirituba II (Itapeva SP, Brazil), it was designed the roof system NLB (nailed laminated beams) which covered 35 houses. In another context, the Sepé Tiaraju, located in the municipality of Serra Azul SP (Brazil), it was designed the roof system in prefabricated wood panels, applied in 67 houses. The strategy for collecting data about the product and the process occurred throughout the production chain of roofing systems, starting with the participatory design, through the found social reality, to implementation of proposals in each rural settlement. The development and selection of the proposed solutions counted with the direct involvement of the families throughout the process. With the results it is concluded that both prefabricated roof systems meet the conditions of cost reductions of materials and labor, improving the quality of the finish of the roof system, even when working in situations with precarious infrastructure. The relevance of this research is to add not common value to the roof of rural housing, enabling the replication of the principles in similar situations and demonstrating that the prefabrication and participatory design can be viable alternatives to organized communities.

Technology needs to be designed considering various usage contexts. Today many parents use social media. Children are allowed to have a social media account by some social media websites if they are above a certain age. Social media is diverse in content that it is sometimes suitable for viewing by children and sometimes not. Parents sometimes wish to show some specific content from their social media page to their children. The page that they wish to show could have a content that is not suitable for viewing by children. This presents a problem to both the parent and child as users who sit together to view the intended content. This thesis intends to study on the different use contexts when the parent and child would want to sit together viewing a social media page sharing the same device. The study would also try to understand how the parent would envision to have the social media user interface during such usage contexts. This study also aims to trigger further research on the problems related to computer mediated interaction of people and children using the virtual sphere especially in social media encompassing the data analytics that would be needed in the background to ease such a communication.

A usabilidade é um aspecto de grande importância na área de produtos eletromédicos, pois um mau uso de algum produto pode acarretar sérios problemas de saúde ao paciente ou até mesmo sua morte. De forma a mitigar tal problema, a NBR IEC 60601-1-6 (referente à usabilidade nos produtos eletromédicos) passou a ser obrigatória para certificação de produtos eletromédicos no Brasil a partir de dezembro de 2015. Entretanto, tal norma ainda deixa muitas dúvidas de aplicação a equipes de projeto. Para mitigar esse problema, alguns temas da literatura poderiam ser aplicados. Um deles é o de Processo de Desenvolvimento de Produtos (PDP). Os modelos de PDP e os métodos de gestão de requisitos poderiam melhorar os processos das empresas da área eletromédica, assim como a teoria de User-Centred Design (UCD) e métodos voltados ao usuário poderiam melhorar o envolvimento do usuário no desenvolvimento de produtos e consequentemente a sua usabilidade. Entretanto, pôde-se notar que as empresas de pequeno porte não seguem as orientações da teoria, algumas sequer as conhecem, e quando conhecem, possuem dificuldades em suas aplicações. O objetivo dessa pesquisa é desenvolver um framework para aplicação de métodos de UCD no PDP de empresas de produtos eletromédicos, com o foco na fase de desenvolvimento de conceito, contendo a integração de métodos de UCD e de gestão de requisitos com a teoria dos modelos de PDP e com os requisitos normativos. Para tal, é seguida nessa pesquisa uma metodologia que compreende três fases: (I) fundamentação teórica e empírica (realizada por revisão da literatura e estudos de caso exploratórios), (II) desenvolvimento do framework (por meio de modelagem), e (III) verificação (com utilização de focus group e entrevistas com especialistas). A avaliação do framework foi considerada positiva. A sequência e a inclusão de dos passos se mostrou válida e lógica; os métodos propostos e o material de apoio elaborado foram considerados pertinentes ao desenvolvimento de produtos; e a organização de todas as entregas, juntamente com sua conexão com os passos, ajuda muito na elaboração do arquivo de engenharia de usabilidade. O framework desenvolvido ajuda as equipes de projeto a envolver o usuário no desenvolvimento de produtos e na busca por produtos com maior usabilidade. Além dessas contribuições empíricas, essa pesquisa traz a contribuição teórica da conexão do PDP com detalhamento de métodos. / Usability is an aspect of great importance in the area of electromedical products, since a misuse of some product can cause serious health problems to the patient or even his death. In order to mitigate such a problem, NBR IEC 60601-1-6 (referring to usability in electromedical products) became mandatory for certification of electromedical products in Brazil since December 2015. However, this standard still leaves many application doubts to project teams. To mitigate this problem, some literature issues could be applied. One is the Product Development Process (PDP). PDP models and requirements management methods could improve the processes of companies in the electromedical area, as well as User-Centred Design (UCD) theory and user-oriented methods could improve user involvement in product development and consequently its usability. However, it may be noted that small companies do not follow the theory\'s guidelines, some do not even know them, and when they do, they have difficulties in their applications. Thus, the objective of this research is to develop a framework for the application of UCD methods in the PDP of electromedical products companies, focusing on the concept development phase, containing the integration of UCD methods and requirements management with the theory of PDP models and with the standard requirements. For this, a methodology is followed, which includes three phases: (I) theoretical and empirical foundation (done by literature review and exploratory case studies), (II) framework development (through modeling), and (III) verification (using focus group and interviews with specialists). The framework evaluation was considered positive. The sequence and inclusion of the steps proved to be valid and logical; the methods proposed and the developed supporting material were considered relevant to the development of products; and the organization of all deliveries, along with its connection to the steps, helps a lot in the development of the usability engineering file. The developed framework helps project teams to engage the user in product development and the search for products with greater usability. Besides these empirical contributions, this research brings the theoretical contribution of the connection of the PDP with details of methods.
