Internet of Things is expanding to the areas such as healthcare, home management, industrial, agriculture, and becoming pervasive in our life, resulting in improved efficiency, accuracy and economic benefits. Smart sensors with embedded interfacing integrated circuits (ICs) are important enablers, hence, variety of smart sensors are required. However, each type of sensor requires specific interfacing chips, which divides the huge market of sensors’ interface chips into lots of niche markets, resulting in high develop cost and long time-to-market period for each type. Software defined sensor is regarded as a promising solution, which is expected to use a flexible interface platform to cover different sensors, deliver specificity through software programming, and integrate easily into the Internet of Things. In this work, research is carried out on the design and implementations of ultra low power analog interface circuits toward software defined sensors for healthcare services based on Internet of Things.    This thesis first explores architectures and circuit techniques for energy-efficient and flexible analog to digital conversion. A time-spreading digital calibration, to calibrate the errors due to finite gain and capacitor mismatch in multi-bit/stage pipelined converters, is developed with short convergence time. The effectiveness of the proposed technique is demonstrated with intensive simulations. Two novel circuit level techniques, which can be combined with digital calibration techniques to further improve the energy efficiency of the converters, are also presented. One is the Common-Mode-Sensing-and-Input-Interchanging (CSII) operational-transconductance-amplifier (OTA) sharing technique to enable eliminating potential memory effects. The other is a workload-balanced multiplying digital-to-analog converter (MDAC) architecture to improve the settling efficiency of a high linear multi-bit stage. Two prototype converters have been designed and fabricated in 0.13 μm CMOS technology. The first one is a 14 bit 50 MS/s digital calibrated pipelined analog to digital converter that employs the workload-balanced MDAC architecture and time-spreading digital calibration technique to achieve improved power-linearity tradeoff. The second one is a 1.2 V 12 bit 5~45 MS/s speed and power-scalable ADC incorporating the CSII OTA-sharing technique, sample-and-hold-amplifier-free topology and adjustable current bias of the building blocks to minimize the power consumption. The detailed measurement results of both converters are reported and deliver the experimental verification of the proposed techniques.     Secondly, this research investigates ultra-low-power analog front-end circuits providing programmability and being suitable for different types of sensors. A pulse-width- -modulation-based architecture with a folded reference is proposed and proven in a 0.18 μm technology to achieve high sensitivity and enlarged dynamic range when sensing the weak current signals. A 8-channel bio-electric sensing front-end, fabricated in a 0.35 μm CMOS technology is also presented that achieves an input impedance of 1 GΩ, input referred noise of 0.97 Vrms and common mode rejection ratio of 114 dB. With the programmable gain and cut-off frequency, the front-end can be configured to monitor for long-term a variety of bio-electric signals, such as electrooculogram (EOG), electromyogram (EMG), electroencephalogram (EEG) and electrocardiogram (ECG) signals. The proposed front-end is integrated with dry electrodes, a microprocessor and wireless link to build a battery powered E-patch for long-term and continuous monitoring. In-vivo test results with dry electrodes in the field trials of sitting, standing, walking and running slowly, show that the quality of ECG signal sensed by the E-patch satisfies the requirements for preventive cardiac care.    Finally, a wireless multimodal bio-electric sensor system is presented. Enabled by a customized flexible mixed-signal system on chip (SoC), this bio-electric sensor system is able to be configured for ECG/EMG/EEG recording, bio-impedance sensing, weak current stimulation, and other promising functions with biofeedback. The customized SoC, fabricated in a 0.18 μm CMOS technology, integrates a tunable analog front-end, a 10 bit ADC, a 14 bit sigma-delta digital to current converter, a 12 bit digital to voltage converter, a digital accelerator for wavelet transformation and data compression, and a serial communication protocol. Measurement results indicate that the SoC could support the versatile bio-electric sensor to operate in various applications according to specific requirements. / <p>QC 20151221</p>

La thèse contribue à comprendre le rapport qui peut s’établir entre expérience spécifique de la culture et relation à la culture, dans le cas particulier de la visite muséale. C’est la notion d’ajustement qui est proposée pour rendre compte de ce rapport. Celle-ci désigne un régime d’interaction au cours duquel, l’acteur social s’engage dans un corps-à-corps avec un dispositif de communication et interprète la situation en mobilisant des représentations de cette situation et de son rôle de visiteur. Aussi la première partie montre – grâce à un détour par les théories de l’ethnométhodologie, des représentations sociales et de l’interaction médiatisée – comment le cadre méthodologique de la thèse a été construit pour appréhender la pratique du visiteur en train de se déployer. Deux terrains ont été choisis pour cette analyse : une exposition temporaire, dans les salles du musée du Louvre, qui engage une situation postulée comme une expérience de visite ; et un jeu pédagogique sur téléphone portable, mené dans les salles du musée des arts et métiers, qui ébranle, précisément, ce prérequis. La deuxième partie présente ainsi une analyse qui met en regard l’étude de la préfiguration des situations de communication par les dispositifs pour chacun des terrains, et la dynamique de leur redéfinition par les visiteurs, dans un ajustement progressif. L’exemple du texte, en tant qu’il est un opérateur de médiation aux objets et aux savoirs, permet de voir comment le visiteur s’ajuste à une double anticipation (l’activité de lecture et l’activité de visite), dans une tension entre la caractérisation de ses postures de lecture, la retextualisation des propositions et la reformulation permanente du projet général de la visite. La troisième partie consiste alors à regarder comment le visiteur caractérise la situation qu’il est en train de vivre, non plus seulement à partir de son expérience de lecture, mais à partir de sa compréhension de son activité générale de visite. On observe alors que les visiteurs vivent profondément une situation d’interaction médiatisée, c'est-à-dire qu’à la fois ils postulent une forme de dialogue avec un concepteur qui leur « parle » et en même temps ils identifient en permanence le geste expographique qui consiste à mettre en scène un espace. Cette situation est vécue dans un jeu d’attention très forte aux caractéristiques sémiotiques de l’exposition et de suspension volontaire de l’incrédulité. Pour terminer, l’analyse a permis de mettre au jour trois formes d’ajustement caractéristiques : (1) la mobilisation et construction de figures de parcours et de figures de visiteurs qui médiatisent le rapport de l’acteur à sa propre pratique et qui lui permettent de juger la situation de communication qu’il est en train de vivre. (2) La prise de rôle qui s’élabore à partir de la nécessité de trouver un cadre pertinent d’interprétation pour l’activité. (3) Et enfin, le jeu entre description de l’activité et cadre général d’interprétation qui permet au visiteur de construire un rapport plus général à la culture. / The thesis contributes to facilitate an understanding of the relation that can be established between a specific experience of culture and a relationship to culture, in the specific case of the museum visit. The notion of adjustment is proposed in order to account for this relation and points to a system of interaction during which the social agent is engaged in an embodied relationship with a dispositif (or apparatus) of communication and interprets the situation by using representations of this situation and of his role as a visitor. Thanks to a detour via the theories of ethnomethodology, of the social representations and of the mediated interactions, the first part shows how the methodological framework of the thesis has been built in order to apprehend the practice of the visitor as it is being deployed. Two case studies have been chosen for this analysis, a temporary exhibition in the galleries of the museum le Louvre, which engages a situation formulated as an experience of a visit; and a pedagogical game on mobile phone, set in the galleries of the museum arts et metiers, which disturbs this previous assumption. The second part then presents an analysis that puts into dialogue the study of the configuration of situations of communication through the dispositifs at play in each of these situations, and the dynamic of their redefinition by the visitors, through a progressive adjustment. The example of the text since it is considered to be a means of mediation with objects and with knowledge, reveals how the visitor adapts to situation that anticipate a double usage (reading and visiting), with a tension between the characterisation of his gesture and of his reading postures, the retextualisation of the propositions and the permanent reformulation of the general project of the visit. The third part consists in looking at how the visitor defines the situation that he is going through, not only from his experience of reading, but also from his general understanding of his visit. We then observe that the visitors profoundly live a situation of mediated interaction, which means that they simultaneously postulate a form of dialogue with a conceptor that “speak” to them and constantly identify the expographic gesture that consists in staging a space. This situation is experienced through a game of strong attention to the semiotic characteristics of the exhibition and through a willing suspension of disbelief. Finally, the analysis has allowed to bring to light three characteristic forms of adjustment: (1) The mobilisation and construction of figures of paths and figures of visitors which mediate the relationship between the agent and his own practice and which allow him to judge the situation of communication that he is going through. (2) The fulfilment of a role that is being elaborated from the necessity to find a relevant framework of interpretation for the activity. (3) And finally, the game between the description of the activity and the general framework of interpretation that allows the visitor to construct a broader relationship to culture.

Este trabalho explora a gerência de segurança e cooperação de aplicações em sistemas distribuídos móveis. Neste contexto, é feito um estudo sobre os diferentes middlewares para ambientes móveis (mobile middleware): suas capacidades de enfrentar os desafios da mobilidade e da segurança. As análises do estudo mostram que esses middlewares devem possuir características que lhes permitem uma melhor adaptação às necessidades das aplicações e à natureza dos ambientes móveis. Os middlewares existentes pouco abordam a questão da segurança. A segurança ainda é um problema complexo que deve ser gerido em todos os níveis de um sistema distribuído móvel, incluindo novos mecanismos. Com base nessa análise, foi desenvolvido um modelo de gerência de segurança que implementa um mecanismo de autenticação mútua, confidencialidade, detecção de intruso e controle de acesso em ambientes móveis. O objetivo é garantir a confiabilidade, a disponibilidade de serviços e a privacidade do usuário através da tecnologia PET - Privacy-Enhancing Tecnologies. A idéia é fundamentada em agentes interceptadores e autoridades de segurança que distribuem tíquetes de segurança e controlam o acesso a recursos e espaços de tuple do ambiente. O estudo de caso apresentou resultados satisfatórios que permitem julgar a pertinência do modelo proposto. O modelo será integrado a um sistema de e-saúde. / The work exploits the security management and the cooperation of applications in mobile distributed systems. In this context a study of different mobile middleware is made. The study examines their capacities to face the challenges of mobility and security issues. The analysis shows that the existing middleware has very few approaches on security problems; security is still a complex issue to be managed in all the levels of mobile distributed system including new mechanisms. Based on this analysis, a security management model is developed that implements a mechanism for mutual authentication, confidentiality, intrusion detection, access control of mobile agents in mobile environments, ensures services availability and user privacy, through technology PET (Privacy-Enhancing Technologies). The idea is based on interceptor agents and security authorities that distribute security tickets and control the access to resources and Tuple spaces in mobile environment. The proposed model presents good performance and is integrated to an e-health system: Relationship Management with Chronic Patient GRPC.

Este trabalho de pesquisa aprofunda o conhecimento associado aos sistemas de automação modernos baseados em redes de controle LonWorks®, visando torná-los mais facilmente utilizáveis como meios de implementar ambientes pervasivos. Para tanto, foi proposto um modelo de relacionamento dinamicamente reconfigurável entre dispositivos de uma rede de controle, que permite conferir a um sistema de automação distribuído algumas características previstas na computação pervasiva. É proposta uma extensão do modelo de objetos na tecnologia LonWorks®, utilizando conceitos de middleware, de forma a conferir aos módulos da rede a capacidade de auto-gerenciamento dinâmico, de modo a modificar os seus comportamentos à medida que novas situações sejam identificadas. A extensão proposta foi aplicada experimentalmente, visando a sua validação e refinamento, como o sistema de comunicação interno de uma empresa, substituindo os PABXs convencionais, considerado em maiores detalhes. Constatou-se a impossibilidade de sua implementação com a tecnologia LonWorks® atual, que utiliza conexões estáticas, necessitando de um operador ou integrador para configurá-las, caso não seja adotada a extensão proposta. Como estudo de caso o projeto de um PABX baseado na tecnologia LonWorks® foi avaliado e discutido, contribuindo para a geração de uma nova metodologia de concepção de sistemas de automação que possam atender algumas propostas previstas na computação pervasiva. É proposto integrar a Tecnologia da Informação e Comunicação, com as ações e os comportamentos convencionais que as pessoas apresentam. Essa metodologia proposta supera os desafios de projetistas de sistemas de automação de ambientes, em especial os prediais, e obtém integração entre processos de forma que as pessoas não percebam que estão interagindo com um computador, cuja presença deverá cada vez mais se tornar onipresente. Além de facultar interfaces fáceis e naturais, tem-se também a incorporação dos conceitos da computação sensível a contexto nos sistemas de automação. / Pervasive or ubiquitous computing, proposes the integration between the information and communication technology with the actions and common behaviors presented by people. One of the challenges that it imposes to the environmental automation systems developers, specially building automation developers, is that this integration is processed in such a way that people do not realize they are interacting with a computer, thus its presence becomes omnipresent. Besides the need of an easy and natural interface, there is also the need to incorporate the sensitive computing context to the automation systems. The current control networks utilized in automation systems, building, home and industrial control do not show resources that support the requirements of pervasive computing. This research intend to improve the knowledge associated to modern automation systems, based on LonWorks® control networks, viewing to make them more easily usable as ways to implement pervasive environments. For that, a dynamically settable relationship model was proposed between the intelligent devices of a control network, which allows providing some foreseen characteristics on pervasive computing in a distributed automation system. A LonWorks® technology object model extension is proposed, using middleware concepts, in a dynamic way, to modify behaviors when new situations are identified. The proposed extension was experimentally applied to a few use cases, aiming at its validation and refinement, such as the internal communication of a company, which replaces the usual PABX, which was considered in greater detail. The impossibility of its implementation was found with the current technology, without the use of the proposed extension. Those cases were evaluated and discussed, contributing to a new automation system concept technology that can support provided proposals on pervasive computing.

Ambientes Pervasivos são ambientes povoados por diversos dispositivos (sensores, atuadores, etc.) e aplicações de software (locais ou distribuídas) incorporadas nestes ambientes físicos de forma transparente para o usuário. Ambientes deste tipo devem ser capazes de interagir e satisfazer as requisições do usuário de forma autônoma e transparente. Nesse sentido, um dos maiores desafios de pesquisa em ambientes pervasivos é a de estabelecer mecanismos automáticos para compor, de forma dinâmica, funcionalidades que satisfaçam as requisições dos usuários. Nesse sentido, nós partimos da hipótese que mecanismos automáticos de interação entre ambientes e usuários podem ser abordados como um problema de composição automática de serviços em ambientes pervasivos. Portanto, nossa proposta é desenvolver um modelo referência, a partir do qual podem ser implementados sistemas que permitam ao ambiente pervasivo interagir com o usuário de forma natural, automática e dinâmica. Desta forma, o sistema de composição de serviços gerencia e automatiza o processo de resolução de requisições feitas pelo usuário (de forma implícita e/ou explicita) através das funcionalidades (serviços) disponíveis no ambiente ou através de novas funcionalidades criadas pelo processo de composição. Para tal fim, este trabalho apresenta um Modelo de Referência que permita projetar, implementar e avaliar sistemas de composição de serviços que gerenciem e automatizem o processo de interação em diversos tipos de ambientes pervasivos. Nossa proposta traz vantagens como: o baixo acoplamento e a interoperabilidade, isto porque é possível selecionar, integrar e reutilizar de forma eficiente e efetiva serviços heterogêneos provenientes de diversos tipos de dispositivos e/ou aplicações. Além disso, o modelo ontológico WSMO (Web Services Modelling Ontology) nos permite descrever semanticamente as capacidades dos serviços como também as informações contextuais presentes no ambiente, o que torna nosso sistema mais perto de um ambiente pervasivo real como o idealizado por Mark Weiser. / Pervasive environments are populated by several devices (sensors, actuators, etc.) and software applications (local or distributed) incorporated these physical environments transparently to the user. Environments of this type should be able to interact and process user requests autonomously and transparently. In this sense, one of the biggest research challenges in pervasive environments is to establish automatic mechanisms to compose dynamically, features that meet the user requirements. In this sense, we set the hypothesis that automatic mechanisms of interaction between users and environments can be addressed as a problem of automatic composition of services in pervasive environments. Therefore, our proposal is to develop a reference model, from which systems can be implemented to enable the pervasive environment interact with the user in a natural, automatic and dynamic. Thus, the system service composition management and automates the process of resolving requests made by the user (implicitly and / or explicitly) through the functionality (services) available in the environment or through new features created by the process of composition. To this end, this paper presents a Reference Model that allows to design, implement and evaluate systems of composition of services that manage and automate the interaction process in different types of pervasive environments. Our proposal brings benefits such as loose coupling and interoperability, because it is possible to select, integrate and reuse in an efficient and effective heterogeneous services from different types of devices and / or applications. Furthermore, the ontological model WSMO (Web Services Modeling Ontology) allows us to semantically describe the capabilities of the services as well as contextual information in the environment, which makes our system closer to a real pervasive environment as conceived by Mark Weiser.

No. of bitstreams: 1 Marta Cecilia Rabinovitsch Gertel.pdf: 289435 bytes, checksum: 43ff4cd776f52360ea872b71bf47d3ab (MD5) Previous issue date: 2008-07-29 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Introduction: In the field of Speech Therapy it is possible to find questionings on how our clinical intervention could facilitate the insertion of the individual, mainly patients with special needs. This way the context of speech therapy clinic could be directed to help the patient finding his own personal place, a fundamental aspect that will give him the sense of belonging both to his family and to school. The theoretical referential from Winnicott is the base of this research and it has been legitimated in various other researches from the speech therapy area in the sense of revealing ways to welcoming the patient, the complaint and the demand, understating through the therapeutic relation the needs and queries in the life of the individual who comes for treatment. It is important to stress that it is part of the clinic perspective the extension of care to the environment, in this case family and school, whenever necessary. Objective of this work: reflect and discuss the role of the speech therapist in conducting these therapeutic strategies during treatment of a child with Pervasive Developmental Disorder, mainly related to family and school. Methodology: This research is from a clinic-qualitative nature and was developed through a clinic case study of a child suffering from Pervasive Developmental Disorder. The material used was prepared from recorded reports and comprises the clinical material obtained on the family counseling from July 2002 to November 2004. The material cuts obtained portray the route followed through the patient story main point, stressing out significant moments that originated the development of the speech therapy therapeutic process regarding speech communication, social integration in the school and family environment. Results: The patient involved in this study attends normal classes and since speech therapy treatments, presented significant development in both social and family behavior, apart from showing an effective advance in oral communication. Conclusions: Assuming a perspective that leads the treatment to a child in a unique way, the therapeutic focus goes beyond clinic manifestations. To favor a physical and emotional environment able to promote constitutive experiences that respect the singularity of each patient taking into consideration the reality of the family and the community where the social nucleus is inserted. As a consequence ethnic identity, culture and ethics are better understood as fundaments of the human being and therefore as place of rooting and existence. In our understanding therefore the role of Phonoaudiology (speech therapy) could be directed to the creation of situations that will favor each patient process of inclusion in life, with all the respect that every one deserves / Introdução: No campo fonoaudiológico é possível encontrar questionamentos quanto a forma como nossa intervenção clínica pode favorecer a inserção do indivíduo na sociedade, principalmente nos pacientes com necessidades especiais. Nesse sentido, o contexto da clínica fonoaudiológica pode ser direcionado para auxiliar o paciente a encontrar um lugar próprio e pessoal, aspecto fundamental para que lhe seja possível alcançar o sentido de pertencer a sua família e à escola. O referencial teórico de Winnicott embasa esta pesquisa e vem sendo legitimado em vários estudos da área fonoaudiológica, no sentido de desvendar maneiras de acolher o paciente, a queixa e a demanda, compreendendo, assim, por meio da relação terapêutica, necessidades e questionamentos que atravessam a vida da pessoa que chega para atendimento. Cabe ressaltar que faz parte desta perspectiva clínica a extensão dos cuidados ao ambiente, neste caso família e escola, sempre que se fizer necessário. Objetivo do trabalho: refletir e discutir sobre o papel do fonoaudiólogo na condução das estratégias terapêuticas durante o atendimento de uma criança com Transtorno Global do Desenvolvimento, principalmente no que se refere à família e à escola. Método: Esta pesquisa é de natureza clínico-qualitativa e foi desenvolvida por meio de um estudo de caso clínico, de uma criança com Transtorno Global do Desenvolvimento. O material utilizado foi elaborado a partir de registros em forma de relatórios e abrangem o material clínico obtido nos atendimentos à família e à escola, de julho/ 2002 a novembro/2004. Os recortes no material obtido retratam o percurso seguido ao longo do eixo da história do paciente enfatizando os momentos significativos que geraram desenvolvimento do processo terapêutico fonoaudiológico no que se refere à comunicação oral, integração social no ambiente familiar e escolar. Resultados: O paciente envolvido neste estudo freqüenta classe de ensino regular e, a partir dos atendimentos fonoaudiológicos, apresentou desenvolvimento significativo em seu comportamento social e em família, além de efetivo avanço em sua comunicação oral. Conclusões: Ao assumir uma perspectiva que direciona o atendimento para a criança de maneira singular, o enfoque terapêutico coloca-se para além das manifestações clínicas. Procura-se propiciar um ambiente físico e emocional capaz de promover experiências constitutivas que respeitem a singularidade de cada paciente levando em conta a realidade da família e da comunidade onde se encontra inserido aquele núcleo social. Como conseqüência a etnia, a cultura e a ética passam a ser compreendidas como fundantes do ser humano e, portanto, como lugar de enraizamento e existência. Portanto, em nosso entender, a atuação fonoaudiológica pode ser direcionada para a criação de situações que favoreçam o processo [de cada paciente] de inclusão na vida, com o respeito que todas as pessoas merecem

A linguagem e a comunicação são processos fundamentais para o desenvolvimento humano. Mas longe de serem processos inatos ou maturacionais são processos sócio-históricos que se desenvolvem ao longo da vida. Dessa forma, quando as crianças chegam à idade escolar trazem com elas uma linguagem e comunicação oral não como produtos acabados, mas como processos sociais e em desenvolvimento Professores de séries iniciais muitas vezes são surpreendidos quando uma criança não fala, ficando sem ação, pois a expectativa deles é trabalhar apenas com a escrita. Eles pressupõem que oralidade já deveria estar desenvolvida em seus alunos. A escola tem papel fundamental nesse processo de alfabetização, mas também no desenvolvimento da linguagem como um todo incluindo as diversas formas de comunicação possíveis, pois, é de suma importância que a escola acolha todas as pessoas sem discriminações ou preconceitos. Esta pesquisa teve como foco principal propor ações mediadoras com uso de recursos e estratégias de CAA para promover o desenvolvimento da comunicação em sujeitos com TGD. As ações mediadoras foram embasadas nos pressupostos da Teoria Sócio-Histórica, focando em estratégias nas quais a interação vise à comunicação com recursos de CAA de baixa e alta tecnologia como foco principal. O presente trabalho estruturou-se como um estudo de caso (multicaso) de dois sujeitos incluídos nas séries iniciais do ensino fundamental na rede publica municipal da grande Porto Alegre. Ambos os sujeitos tem TGD, sendo que um tem diagnóstico de autismo e o outro de Síndrome de Cornélia de Lange (CdLS). Os resultados a serem apresentados mostram que é possível a utilização da CAA no processo do desenvolvimento de sujeitos não oralizados com TGD, pois, de forma geral, percebe-se que no final da pesquisa os sujeitos ampliaram suas formas de comunicação graças ao uso da CAA. Os indícios de intencionalidade de comunicação que emergiram nos sujeitos com TGD, quando utilizadas ações mediadoras com CAA, se ampliaram de forma significativa chegando os sujeitos a tornarem-se agentes intencionais em diversos momentos das interações. / Language and communication are key processes in human development. But far from being innate or maturational processes, they are socio-historical processes that develop throughout life. Thus, when children reach school age they bring with them the language and oral communication not as a finished product, but as a social process in development. Schoolteachers are often surprised when a child does not speak, and do not know what to do, because their expectation is to work only with writing. They assume that orality should have been already developed in their students. The school has a fundamental role in the process of literacy, but also in language development as a whole, including the various forms of possible communication. Therefore, it is essential that the school accepts all persons without discrimination or prejudice. This research aims to propose mediation actions through the use of resources and strategies of AAC to promote the communication development in subjects with PDD. The mediating actions were based on the principles of the Social-Historical Theory, focusing on strategies in which the interaction aimed at communicating with AAC features of low and high technology. This study was structured as a case study (multicase) of two individuals inserted in the initial grades of elementary public school at Porto Alegre. Both subjects have PDD; one was diagnosed with autism and the other with Cornelia de Lange Syndrome (CdLS). The results presented show that it is possible to use the AAC in the development process of individuals with PDD and with oral language issues because, in general, at the end of the study subjects increased their forms of communication through the use of AAC. The evidence of intentional communication that emerged in subjects with PDD when using mediation actions with AAC have expanded significantly, reaching the subjects and turning them into intentional agents at different times of the interactions.

Because of current technology limitations, the realization of ubiquitous computing observes a limited set of aspects of ubiquitous computing, such as, mobility and context, which are based on services that integrate the users with the resources that are present on a delimited ubiquitous environment (such as in smart spaces). Instead, we explored a different approach, in which services are used not to integrate an individual user with the environment, but to integrate the users present in the environment with one another. One way to realize this aspect is by using content sharing, first-class application dat, that serve as integration medium between users. However, due to the environment complexity and lack of middleware platforms, applications that follow this approach are repeatedly built from scratch using raw techniques. Aiming to provide an infrastructure for the development of this kind of applications, we propose Content Sharing for Smart Spaces (C3S), a middleware that offers a high-level programming model using primitives that are based on a set of content sharing semantics and ubiquitous application concepts. The primitives express a small set of behaviors, such as move, clone, and mirror, which serve as building blocks for developers to implement sharing and content ubiquity features, while the ubiquitous concepts supported by the middleware allow the manipulation of users, groups and ubiquitous applications. We validated our proposal using two different case studies that allowed us to explore these features. Our results show that our middleware provides an easier way to develop sharing-based applications compared to related work found in the literature. / De acordo com Mark Weiser, a computação ubíqua se concentra na integração de maneira despercebida e sem rupturas (seamlessy) de tarefas da computação no cotidiano das pessoas. Por causa das atuais limitações tecnológicas, a realização dessa integração segue um ou mais aspectos da computação ubíqua, por exemplo, de mobilidade ou de contexto, que são baseados em serviços que integram o usuário em um ambiente ubíquo delimitado (como espaços inteligentes). Neste trabalho exploramos uma abordagem diferente, em que os serviços não são utilizados para integrar um usuário individual ao ambiente, mas são utilizados para integrar os usuários presentes no ambiente uns com os outros. Uma maneira de realizar esse aspecto é usando o compartilhamento de conteúdo, dados de primeira classe da aplicação que servem como meio de integrar os usuários. No entanto, devido à complexidade do ambiente de computação ubíqua e à falta de plataformas de middleware, aplicações que seguem esta abordagem são repetidamente construídas a partir “do zero”, usando técnicas não convencionais. Com o objetivo de fornecer uma infraestrutura para o desenvolvimento deste tipo de aplicação, propomos o Content Sharing for Smart Spaces (C3S), um middleware que oferece um modelo de programação de alto nível, usando primitivas baseadas em um conjunto de semânticas de compartilhamento de conteúdo e em conceitos de aplicações ubíquas. As primitivas expressam um conjunto de comportamentos, tais como mover, clonar, e espelhar, que servem como blocos de construção para os desenvolvedores implementarem funcionalidades de compartilhamento, enquanto que os conceitos de ubiquidade permitem a manipulação de usuários, grupos e aplicações ubíquas. A proposta foi validada por meio de dois estudos de caso que exploram esses recursos. Os resultados permitiram concluir que o middleware fornece uma maneira mais fácil de desenvolver aplicativos baseados em compartilhamento em comparação com trabalhos semelhantes encontrados na literatura.
