Moreover, the tasks of day-to-day have been automated. On that basis, the trend that, in the future, mobile devices will have the ability to perform measurements and replace the need deployment of a fixed infrastructure responsible for collecting certain information, simple tasks - like checking prices - could be extinguished. Based on this, the participatory sensing and applying techniques collaboration systems have been gaining focus, and especially improving the collection information. Many are collaborative applications that inform your users they are wondering and thereby create a collaborative community, able to help with collections and receive information through other users. However, although similar in its base, there are tools capable auxiliary developing these applications more easily; reducing time and effort; saving resources to focus on developing better and finishing applications; enabling the creation of the best ways to encourage users and, consequently, better collection and an active community longer. For these reasons, this work proposes a framework capable of assisting in development of systems that integrate the various concepts shown above, with integration into social networks and aid in application development. To this, they were raised important requirements for application of this area from which the architecture and tool design was created. Furthermore, the paper presents a prototype an application using the framework, in order to serve as proof concept thereof. / A cada dia dispositivos móveis são aperfeiçoados, ganham novas funcionalidades, novos sensores, hardware melhor e, com isso, maior capacidade de medir informações do meio em que são utilizados e de processá-las de forma correta. Além disso, as tarefas do dia-a-dia vêm sendo automatizadas. Com base nisso, a tendência de que, no futuro, dispositivos móveis terão a capacidade de realizar medições e substituírem a necessidade de implantação de uma infra-estrutura fixa responsável pela coleta de determinada informação, tarefas simples - como a verificação de preços - poderão ser extinta. Com base nisso, a área de sensoriamento participativo e a aplicação de técnicas de colaboração em sistemas vêm ganhando foco e, principalmente, aprimorando a coleta de informações. Diversas são as aplicações colaborativas que informam aos seus usuários o que estes estão querendo saber e, com isso, criam uma comunidade colaborativa, capaz de ajudar com coletas e receber informações através de outros usuários. No entanto, apesar de parecidas em sua base, não existem ferramentas capazes de auxiliar o desenvolvimento destas aplicações de forma mais fácil; reduzindo tempo e esforço; poupando recursos para o foco em melhor desenvolvimento e acabamento de suas aplicações; possibilitando a criação de melhores formas de incentivo aos usuários e, consequentemente, melhores coletas e uma comunidade ativa por mais tempo. Por estes motivos, esta dissertação propõe um framework capaz de auxiliar no desenvolvimento de sistemas que integram os diversos conceitos mostrados acima, com integração em redes sociais e auxílio no desenvolvimento da aplicação. Para isso, foram levantados requisitos importantes às aplicações desta área a partir dos quais a arquitetura e projeto da ferramenta foi criada. Além disso, o trabalho apresenta um protótipo de uma aplicação utilizando o framework, com a finalidade de servir como prova de conceito do mesmo.

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.
