Serviços de bibliotecas encontram-se intimamente relacionados ao uso de tecnologias da computação, sendo que alguns modelos foram propostos com vistas a fornecer suporte ubíquo a bibliotecas. No entanto, tais modelos não apresentam alguns aspectos que permitem oferecer recursos diferenciados aos usuários, tais como suporte ao bibliotecário, utilização de históricos de atividades de usuários e integração com sistemas de disponibilização de informação mantidos por terceiros. Desta forma, esta dissertação propõe um modelo computacional para suporte a bibliotecas ubíquas, denominado U-Library. O ULibrary disponibiliza recursos e serviços a usuários de bibliotecas com vistas a fornecer apoio ao desenvolvimento de suas tarefas diárias, no que tange a recuperação, o acesso e a manutenção de recursos e serviços de uma biblioteca. Este trabalho discute características presentes em trabalhos relacionados, descreve o modelo U-Library e apresenta aspectos de implementação e avaliação do modelo através de um protótipo. A avaliação do modelo ocorreu utilizando dados reais da Biblioteca do Centro Universitário Univates, no apoio de tarefas diárias de um grupo de voluntários. / Ubiquitous computing aims to make tasks that depend on computing transparent to the users, thus providing resources and services anytime and anywhere. Library services are closely related to the use of computing technologies. Some models have been proposed in order to provide ubiquitous support to libraries. However, such models do not present some aspects that allow to offer differentiated resources to the users, such as librarian support, use of user activity history and integration with systems providing information maintained by third parties. Therefore, this paper proposes a computational model to support ubiquitous library, called U-Library. The U-Library provides resources and services to library users in order to provide support for the development of their daily tasks, regarding the recovery, access and maintenance of resources and services of a library. This dissertation discusses features present in related work, describes the model U-Library and presents aspects of implementation and evaluation of the model through a prototype. The model evaluation has occurred using real data from Library of Centro Universitário Univates, in support to daily tasks of a volunteers group.

Essas mudanças de comportamento foram influenciadas, entre outros, por fatores tecnológicos, pois os turistas agora possuem diversas ferramentas de apoio desde o momento em que se pensa em fazer turismo, durante o turismo propriamente dito, e até mesmo após ele. Com isso, espera-se muito mais dessas ferramentas de apoio no quesito utilidade, confiabilidade e qualidade no serviço prestado. Muitos estudos têm sido conduzidos nesse sentido, diversos avanços já foram alcançados e atualmente já existem ferramentas que atendem várias demandas atuais dos turistas em seus itinerários. No entanto, a maioria delas não levam em consideração alguns aspectos importantes para que o turista seja realmente auxiliado, como por exemplo, encontrar informações turísticas sobre cidades consideradas de pequeno porte ou distantes de locais turísticos expressivos. O que muito se nota nessas ferramentas atuais, até mesmo nas de cunho comercial, é que somente são contempladas as cidades de grande porte, de alto fluxo de turistas. As demais cidades, que também possuem seus atrativos turísticos, são deixadas de lado. Outra característica comum nas ferramentas atuais é que os guias são gerados previamente e são entregues muitos dados estáticos aos turistas. No modelo de arquitetura desenvolvido neste trabalho, a coleta por informações turísticas acontece de maneira dinâmica, realizando buscas de conteúdo na web em diversas bases de conhecimento abertas e que estão em constante atualização. A partir daí essas informações são organizadas e armazenadas em ontologia, e por fim, entregues ao turista, baseadas em princípios de computação ubíqua. Essa capacidade de realizar buscas na web faz com que um número maior de cidades possa ser encontrado e se consiga chegar a um bom nível de satisfação do turista no uso da ferramenta, bem como eleva a percepção do grau de utilidade da arquitetura proposta. Portanto, o objetivo deste trabalho é desenvolver um modelo de arquitetura de sistema para o turismo ubíquo, baseado em dispositivos móveis, chamado de Ataîru, que na língua indígena Tupi-Guarani significa “companheiro de viagem”. O modelo considera dados sobre a localização e perfil do turista, bem como sobre dados climáticos, data e hora do local pesquisado, para prover respostas personalizadas aos turistas. Para avaliar o modelo proposto, foram utilizadas três técnicas pertinentes, a saber: avaliação por cenários, avaliação de desempenho e avaliação de usabilidade. Na avaliação de desempenho mostrou-se a viabilidade do modelo através de testes feitos no ambiente de nuvem computacional. Na avaliação de usabilidade foram convidados voluntários para usarem o aplicativo móvel cliente Ataîru, onde o objetivo foi avaliar a (1º) percepção de facilidade de uso e (2º) percepção de utilidade do aplicativo, e a (3º) percepção de utilidade das informações apresentadas, alcançando percentuais de concordância total de 72,5%, 82,5% e 67,5%, respectivamente e de concordância parcial de 27,5%, 15% e 30%, respectivamente. Isso mostra que o modelo supre a necessidade dos turistas de informações turísticas de cidades consideradas pequenas ou distantes de locais turísticos expressivos, tanto no aspecto quantitativo quanto qualitativo. / The way people do tourism has changed considerably in recent decades. These behavioral changes were influenced, among others, by technological factors, because tourists now have several tools to support from the moment in which it thinks about doing tourism, during the tour itself, and even after it. Thus, it is expected more of these support tools in the category utility, reliability and quality of service provided. Many studies have been conducted in this direction, several advances have been achieved and currently there are already several tools that meet current demands of tourists in their itineraries. However, most of them do not take into account some important aspects for the tourist really be helped, for example, find tourist information about cities considered small or far from significant tourist sites. What very noticeable in these current tools, even in commercial nature, is that only the large cities are contemplated, high flow of tourists. The other cities, which also have their tourist attractions, are set aside. Another common feature in today's tools is that the guides are pre-generated and delivered many static data to tourists. In architectural model developed in this work, the collection of tourist information happens dynamically, making content web searches in several open knowledge bases and are constantly updated. From there the information is organized and stored in ontology, and finally delivered to the tourist, based on principles of ubiquitous computing. This ability to search the web makes a larger number of cities can be found and can reach a good level of tourist satisfaction in using the tool as well as increases the perception of the degree of usefulness of the proposed architecture. Therefore, the objective of this work is to develop a system architecture model for the ubiquitous tourism, based mobile devices, called Ataîru, which in the indigenous language Tupi-Guarani means "traveling companion". The model takes into account data on the location and tourist profile, as well as weather data, date and time of the searched location, to provide personalized answers to tourists. To evaluate the proposed model, we used three techniques relevant, namely: evaluation of scenarios, performance evaluation and evaluation of usability. In performance evaluation proved the viability of the model by testing done in the cloud computing environment. In evaluating usability volunteered invited to use the mobile client application Ataîru, where the objective was to evaluate (1) perceived ease of use and (2) application utility perception, and (3) perceived usefulness of the information presented, increasing percentage of total concordance of 72.5%, 82.5% and 67.5%, respectively, and partial concordance 27.5%, 15% and 30%, respectively. This shows that the model supplies the need of tourist of tourist information about cities considered small or far from significant tourist sites, both in quantitative and qualitative aspect.

Faz-se importante então, desenvolver modelos que permitam não somente compartilhar dados clínicos, mas sim aumentar a longevidade dos dados, melhorar a sua qualidade, tornar os dados independentes da tecnologia usada e cientes de contexto. Neste cenário, o presente trabalho, denominado PEPContextual, consiste em um modelo que faz uso da ciência da situação (situation awareness), explorando informações relacionad as com o ambiente ou com os próprios usuários e onde diversos tipos de contextos são aglomerados de forma a gerar uma visualização mais rica, complexa e inteligente, criando inúmeras possibilidades, dentre elas, a inferência de riscos associados ao paciente. A contribuição principal deste trabalho está relacionada na identificação da dados de PHR do paciente e do uso da ciência da situação a fim de que seja possível realizar inferências de sintomas e possíveis diagnósticos. O modelo foi avaliado de duas formas: A primeira avaliação por estudo de caso confirmou a expectativa de que a aplicação de ciência de situação, baseada no modelo de Endsley, possibilitaria que o modelo de forma ubíqua detectasse riscos associados ao paciente; A segunda avaliação contemplou a usabilidade do modelo, como facilidade de uso e utilidade onde a maioria dos utilizadores considerou que as informações inferidas podem auxiliar diariamente em tratamentos. / Ubuiquitous computing can be defined as information at anytime, anywhere and its grows as a reality on people‘s activities and daily tasks through the diversification and popularization of mobile devices and networks. So, it‘s important create models that allow not only share clinical data, but increase its quality, making it indifferent to technology and context aware. In this case, the present paper, called PEPContextual, is about a model that makes use of situation awareness, exploring environment related information and/or its own users, where several types of contexts are combined looking a richer, complex and smart visualization, creating several possibilities and, among that, the inferrence of associated risks to patients. The main contribution of this paper is related to make use of PHR data and situation awareness in order to inferrence symptoms and some diagnoses. The model was evaluated by two distinct ways: The first evaluation by case study has confirmed the proposal that situation awareness, based on Endsley model, makes possible that the model is capable to find associated risks through ubiquity; The second evaluation measured the usability of the model, as the ease of use and utility where most of users had considered that inferrence information can help on daily treatments.

As people age there is an overwhelming desire to remain in the familiar surroundings of the family home, what is called Aging in Place. But inevitable changes that occur in their lives force the aging adults and their families to consider a move to some form of institutional living. Living at a distance from one another, the adult child attempts to maintain peace of mind concerning the well-being of their aging parents but finds it to be a difficult task. I propose to address this problem by first proposing that technology can help minimize the anxieties experienced by the adult child concerning their aging parents well being by appropriately presenting information on the aging parents daily life. This technological design concept does not require that the aging parent input, or for that matter, do anything other than live their lives as they normally live them. Further, this technology provides this information in a manner that is continuously available to the adult child for either opportunistic or planned perusal. As a single instance of the technological design concept proposed above, the Digital Family Portrait embeds well-being related information into an item commonly found in homes, the picture in a picture frame. The Digital Family Portrait was first tested in a wizard-of-oz field trial, then redesigned based on the outcome of this initial field trial coupled with the results of two lab-based studies and a further informal evaluation. The redesigned Digital Family Portrait was built and installed in the home of an adult child while the sensors to drive it were installed in an aging parents home. A field trial of this installation lasting for one year was conducted. The result of this field trial was to find that the Digital Family Portrait was an acceptable means of resolving certain peace of mind issues for the adult child while not raising privacy. It was found to be used in a socially acceptable manner by the adult child while the aging parent to reported feeling less lonely.

Context-aware computing aims at making mobile devices sensitive to the social and physical settings in which they are used. A necessary requirement to achieve this goal is to enable those devices to establish a shared understanding of the desired settings. Establishing a shared understanding entails the need to manipulate sensed data in order to capture a real world situation wholly, conceptually, and meaningfully. Quite often, however, the data acquired from sensors can be inexact, incomplete, and/or uncertain. Inexact sensing arises mostly due to the inherent limitation of sensors to capture a real world phenomenon precisely. Incompleteness is caused by the absence of a mechanism to capture certain real-world aspects; and uncertainty stems from the lack of knowledge about the reliability of the sensing sources, such as their sensing range, accuracy, and resolution. The thesis identifies a set of criteria for a context-aware system to capture dynamic real-world situations. On the basis of these criteria, a distributed architecture is designed, implemented and tested. The architecture consists of Primitive Context Servers, which abstract the acquisition of primitive contexts from physical sensors; Aggregators, to minimise error caused by inconsistent sensing, and to gather correlated primitive contexts pertaining to a particular entity or situation; a Knowledge Base and an Empirical Ambient Knowledge Component, to model dynamic properties of entities with facts and beliefs; and a Composer, to reason about dynamic real-world situations on the basis of sensed data. Two additional components, namely, the Event Handler and the Rule Organiser, are responsible for dynamically generating context rules by associating decision events ? signifying a user?s activity ? with the context in which those decision events are produced. Context-rules are essential elements with which the behaviour of mobile devices can be controlled and useful services can be provided. Four estimation and recognition schemes, namely, Fuzzy Logic, Hidden Markov Models, Dempster-Schafer Theory of Evidence, and Bayesian Networks, are investigated, and their suitability for the implementation of the components of the architecture of the thesis is studied. Subsequently, fuzzy sets are chosen to model dynamic properties of entities. Dempster-Schafer?s combination theory is chosen for aggregating primitive contexts; and Bayesian Networks are chosen to reason about a higher-level context, which is an abstraction of a real-world situation. A Bayesian Composer is implemented to demonstrate the capability of the architecture in dealing with uncertainty, in revising the belief of the Empirical Ambient Knowledge Component, in dealing with the dynamics of primitive contexts and in dynamically defining contextual states. The Composer could be able to reason about the whereabouts of a person in the absence of any localisation sensor. Thermal, relative humidity, light intensity properties of a place as well as time information were employed to model and reason about a place. Consequently, depending on the variety and reliability of the sensors employed, the Composer could be able to discriminate between rooms, corridors, a building, or an outdoor place with different degrees of uncertainty. The Context-Aware E-Pad (CAEP) application is designed and implemented to demonstrate how applications can employ a higher-level context without the need to directly deal with its composition, and how a context rule can be generated by associating the activities (decision events) of a mobile user with the context in which the decision events are produced.

Ubiquitous computing application developers have limited options for a practical activity and location sensing technology that is easy-to-deploy and cost-effective. In this dissertation, I have developed a class of activity monitoring systems called infrastructure mediated sensing (IMS), which provides a whole-house solution for sensing activity and the location of people and objects. Infrastructure mediated sensing leverages existing home infrastructure (e.g, electrical systems, air conditioning systems, etc.) to mediate the transduction of events. In these systems, infrastructure activity is used as a proxy for a human activity involving the infrastructure. A primary goal of this type of system is to reduce economic, aesthetic, installation, and maintenance barriers to adoption by reducing the cost and complexity of deploying and maintaining the activity sensing hardware. I discuss the design, development, and applications of various IMS-based activity and location sensing technologies that leverage the following existing infrastructures: wireless Bluetooth signals, power lines, and central heating, ventilation, and air conditioning (HVAC) systems. In addition, I show how these technologies facilitate automatic and unobtrusive sensing and data collection for researchers or application developers interested in conducting large-scale in-situ location-based studies in the home.

This dissertation is based upon the work within a number of research projects, five of which are presented in detail. The work follows the direction of research laid out by the Ubiquitous Computing and Augmented Reality research programs and concerns the broad question of where to go as we seek to take digital technology, and human interactions with this technology, beyond the traditional desktop computer. The work presented takes a design-oriented approach to Human Computer Interaction research. Five prototype systems are presented: Ambient displays for remote awareness, a navigation device providing guidance through tactile cues, a personal device for wastewater plant operators, paper cards enabling control of video playback, and a cell phone that enables you to ‘talk silent’. It is discussed how these prototypes, despite obvious differences, all reflect the same overall attitude towards the role of digital technology. It is an attitude emphasizing that integration of digital technology with everyday human activities means making computational power manifest as part of a larger patchwork of resources. Furthermore, it is an attitude promoting the design of digital technology that leaves the control and initiative with people and their earned ability to take appropriate action when faced with the particularities of the social and physical settings encountered in everyday life beyond the computer screen. In other words, this dissertation brings forward, by using five prototypes as examples, an attitude that encourages us to recognize, embrace, and take advantage of, the fact that human interaction with digital technology takes place, not in a vacuum, but in a rich and diverse world full of many resources for human action other than the digital technology we bring about. / <p>In collaboration with School of Arts and Communication, Malmö University, Sweden.</p>

Services based on the Information and Communications Technologies (ICT) are present more and more in the lives of people. The advancement of ICT in technical and social acceptance terms has led the creation of new models of service provision. These provision models involve further integration with people's activities so that are not only present in their professions or civic space but also in a more intimate areas related to their own identity. So it is now common to find services aware of user's health, their domestic habits, ideology, etc. Therefore, the analysis of existing services must be open out to include other aspects related to the way of being and feeling of their members. This way is possible to ensure both the technical correctness of its features as promoting safe and respectful solutions both of civic rights as the way of being and feeling of its members. From the engineering point of view, the user perspective has historically encompassed under the concept of technological acceptance. Within this field can be interpreted as friendly solutions adapted to users will encourage the acceptance by them. Solution acceptance is desirable although it is difficult to ensure. This difficulty is due to the lack of the number of variables that affect the acceptance of technological solutions and the difficulty of optimizing the known variables. In this thesis it is studied and characterized one of the variables that affect the acceptance of existing services: confidence. Confidence is defined in psychological terms, providing its characterization with the aim of be used in typical methods of engineering. Also different tools are proposed to facilitate the optimization of this confidence in services whose complexity establishes this variable in a basic issue to improve acceptance. Health services deployed in a home have been chosen as working context for this thesis. This scenario presents a number of acceptance restrictions on the technology used to create services and how they manage the acquired user information. It comes to highly sensitive and delocalized services that can affect to the user's perception of the environment, the home, and generate fear or rejection to prevent final adoption as a valid solution. Once defined the generic framework, the main objective of this dissertation is focused on promote the acceptance of new pervasive and personalized health services and their deployment in domestic intelligent environments through a layout that promotes a psychological state of confidence in users. To achieve this goal, a set of results, both conceptual, technological and experimental, have been provided. In particular, it has offered a complete characterization of the feeling of confidence from a viewpoint of engineering and a definition of sensitive or delocalized pervasive service. Furthermore, a method for the inclusion of the Interaction Design discipline in engineering processes of such services through a set of patterns of interaction is offered. Finally, this thesis provides the development of a software architecture to ensure proper deployment of these pervasive sensitive services in intelligent environments in a confident way. Discussion of the results suggests the extension of the deployment model to different services of the Information Society that handle sensitive data both in the context of the digital home and other settings where the user perform everyday activities such as work spaces or schools. The future work lines include the imminent need to apply the results to ongoing developments, within research projects in those the author takes part, and the development of new research lines aimed at creating new spaces and interaction technologies as advanced accessible interfaces, toys of the future, confident visualization systems or security systems based on the condition of the user. / Tjänster baserade på informations- och kommunikationsteknik (IKT) blir allt mer vanligare i människors liv. För att främja acceptansen för IKT i både tekniska och sociala aspekter av människors liv har nya modeller för dessa tjänster skapats. Dessa modeller har en närmare knytning till människors verksamhet så att de inte bara förekommer i deras yrken eller fritid men också i mer intima områden som anknyter till individens egen identitet. Det är nu därför vanligt att hitta tjänster som tar hänsyn till användarens hälsa, vanor, ideologi, etc.  En analys av befintliga tjänster måste inkludera dessa aspekter men även användarnas känsla av identitet och medlemskap. På detta sätt är det möjligt att säkerställa den tekniska riktigheten hos dessa funktioner som i sin tur borgar för säkra och respektfulla lösningar som tar hänsyn till medlemmarnas medborgerliga rättigheter likväl som deras känsla av identitet och medlemskap. Historiskt sett, och ur ett tekniskt perspektiv, har användarperspektivet omfattats under begreppet teknisk acceptans. Inom detta område har användarvänliga lösningar anpassade till användarna själva uppmuntrat acceptans av dem. Acceptans av lösningar är önskvärt även om det är svårt att säkerställa. Denna svårighet beror på avsaknaden av antalet variabler som påverkar acceptansen av tekniska lösningar och svårigheten att optimera de kända variablerna. I denna avhandling studeras och karaktäriseras en av de variabler som påverkar acceptansen av befintliga tjänster: förtroende. Förtroendet definieras i psykologiska termer med syftet att kunna använda termen i typiska metoder för teknik. Det föreslås också olika verktyg för att underlätta optimering av detta förtroende inom tjänstesektorn. Hälso- och sjukvård i hemmet har valts som scenario för denna avhandling. Detta scenario presenterar ett antal restriktioner med avseende på acceptansen av den teknik som används för att skapa tjänster och hur dessa tjänster hanterar den förvärvade användarinformationen. För användaren är situationen mycket känslig och de erbjudna tjänsterna kan påverka användarens uppfattning av miljön och hemmet och/eller generera rädsla eller avsmak för att acceptera lösningen. När den generiska ramen är etablerad är det huvudsakliga syftet med denna avhandling att främja acceptans av nya tjänster för personlig hälsovård och deras användning i hemmet. Detta skall uppnås genom en layout som främjar ett psykologiskt förtroende hos användarna. För att uppnå detta mål har en uppsättning resultat, både begreppsmässiga, tekniska och experimentella, analyserats. Framför allt har en fullständig karaktärisering gjorts av känslan av förtroende från en teknologisk synvinkel och en definition av en känslig och allomfattande tjänst. Dessutom framläggs en metod för införandet av interaktionsdesign i de aktuella tjänsterna genom ett antal interaktionsmönster. Slutligen behandlar denna avhandling utvecklingen av en mjukvaruarkitektur för att säkerställa en korrekt användning av dessa känsliga tjänster. Resultaten pekar på att distributionsmodellen även kan användas för andra tjänster i informationssamhället där användaren utför vardagliga sysslor, såsom i det digitala hemmet eller andra miljöer (t.ex. skolor och arbetsplatser), där känsliga uppgifter hanteras. De framtida arbetsuppgifterna omfattar det överhängande behovet av att tillämpa resultaten på den pågående utvecklingen av forskningsprojekt som författaren är involverad i. Detta omfattar även utveckling av ny forskning som syftar till att skapa ny interaktionsteknik t.ex. avancerade gränssnitt, framtida leksaker, säkra visualiseringssystem eller säkerhetssystem baserat på användarens hälsa/tillstånd. / <p>This PhD research has been conducted under a double PhD agreement degree between the School of Telecommunications Systems and Engineering (ETSIST) at the Technical University of Madrid (UPM) in Spain and the School of Technology and Health (STH) at the Royal Institute of Technology (KTH) in Sweden.</p><p>QC 20160129</p>
