Atacan, Pamir Naz. "Smart Products: Technological Applications Vs User Expectations." Master's thesis, METU, 2010. http://etd.lib.metu.edu.tr/upload/12612450/index.pdf.
Full textAbstract:
This thesis focuses on the technological trends in smart products, and analyzes their conformity to the user expectations. The advances in computation technologies have totally revolutionized the product concept, and with the integration of microchips, software and sensors into the classical everyday objects, smart products, able to sense the context, reason about the sensed data and act according to the situation, have emerged. This new way of computing basing on the ubiquitous and calm computing visions, has distributed the digital information into the surrounding environment, and once freed from the limited resources provided by the classical desktop based computing, attempted to enhance user product communication and collaboration in everyday environments. Via their sensing - decision making - acting process and advanced interaction capabilities, smart products have gained the ability to better interpret user needs and intuitively communicate with users through simplified interfaces involving the majority of the senses without even disturbing or overburdening their users. The study first, throughout a literature review, examines these improvements in computation technologies and determines the trends related to smart products. An empirical research is then conducted to find out to what extend user expectations from smart products overlap with the ongoing researches in this area. The findings including users&rsquoconception about smartness and expectations from different types of smart products are analyzed regarding to the technological trends to deduce the coherence between literature&rsquo
s orientation and user preferences. The study considered the technological trends as a database and takes the user expectations as the design motivation.

Before the recent advances in sensing, actuation, computing and communication technologies, the integration between the digital and the physical environment was limited.
Humans linked those two worlds by collecting data about the physical environment before feeding it into the digital environment, and by changing the state of the physical environment based on the state of the digital environment.
The incorporation of computing, communication, sensing, and actuation technologies into everyday physical objects has empowered the vision of the Internet of Things (IoT). Things can autonomously collect data about the physical environment, exchange information with other things, and take actions on behalf of humans. Application domains that can benefit from IoT include smart buildings, smart cities, smart water, smart agriculture, smart animal farming, smart metering, security and emergencies, retail, logistics, industrial control, and health care.
For decades, building automation, intelligent buildings, and more recently smart buildings have received a considerable attention in both academia and industry. We use the term smart built environments (SBE) to describe smart, intelligent, physical, built, architectural spaces ranging from a single room to a whole city. Legacy SBEs were often closed systems operating their own standards and custom protocols. SBEs evolved to Internet-connected systems leveraging the Internet technologies and services (e.g., cloud services) to unleash new capabilities. IoT-enabled SBEs, as one of the various applications of the IoT, can change the way we experience our homes and workplaces significantly and make interacting with technology almost inevitable. This can provide several benefits to modern society and help to make our life easier. Meanwhile, security, privacy, and safety concerns should be addressed appropriately.
Unlike traditional computing devices, things usually have no or limited input/output (I/O) capabilities. Leveraging the ubiquity of general-purpose computing devices (e.g., smartphones), thing vendors usually provide interfaces for their products in the form of mobile apps or web-based portals. Interacting with different things using different mobile apps or web-based portals does not scale well. Requiring the user to switch between tens or hundreds of mobile apps and web-based portals to interact with different things in different smart spaces may not be feasible. Moreover, it can be tricky for non-domestic users (e.g., visitors) of a given SBE to figure out, without guidance, what mobile apps or web-based portals they need to use to interact with the surrounding.
While there has been a considerable research effort to address a variety of challenges associated with the thing-to-thing interaction, human-to-thing interaction related research is limited. Many of the proposed approaches and industry-adopted techniques rely on more traditional, well understood and widely used Human-Computer Interaction (HCI) methods and techniques to support interaction between humans and things. Such techniques have mostly originated in a world of desktop computers that have a screen, mouse, and keyboard. However, SBEs introduce a radically different interaction context where there are no centralized, easily identifiable input and output devices. A desktop computer of the past is being replaced with the whole SBE. Depending on the task at hand and personal preferences, a user may prefer to use one interaction modality over another. For instance, turning lights on/off using an app may be more cumbersome or time-consuming compared to using a simple physical switch.
This research focuses on leveraging the recent advances in IoT and related technologies to support user interactions with SBEs. We explore how to support flexible and adaptive multimodal interfaces and interactions while providing a consistent user experience in an SBE based on the current context and the available user interface and interaction capabilities.PHD

We explore how to support a flexible, adaptive, and multimodal interaction experience between users and SBEs using a variety of user interfaces and proposed interaction techniques.

Full textAbstract:
Context. Nowadays, mobile applications and services have occupied an essential part in our daily life. We use them to fulfill our needs for communication, news, or entertainment. Within a fierce competitive market, mobile applications need continually improvement through collections of user feedback to satisfy users’ needs. However, in mobile applications, lack of a comprehensive consideration in designing feedback mechanism makes it difficult to efficiently collect user feedback. It shows only approximate one third online user reviews that contain helpful information for improvement. In addition, users may be disturbed by feedback request, result in rejecting to provide feedback. Objectives. This study aims to provide a comprehensive consideration for elicitation of user feedback in mobile applications. Methods. This study followed a mixed qualitative-quantitative research approach. Firstly, we conducted an experiment and a semi-structured interview to investigate how do users provide feedback when they are using a mobile application. Then a content analysis and a statistical analysis were conducted for analyzing collected data. Results. Users’ preference of feedback approaches and the encouraging/discouraging factors for users to provide feedback were identified. We also assessed user-perceived suitable timings for interruption of feedback request. Conclusions. The result shows, generally, users prefer to provide feedback when asked by feedback request. Three encouraging factors and Three discouraging factors are identified. The beginning of mobile application execution is perceived as best moment for interruption of feedback request. In addition, this study also provides a three-time-dimensions approach for researching disturbances caused by interruption of feedback request as well as other peripheral information.

As more people move to cities, space is becoming more limited and expensive. Robotic furniture can increase functionality and optimize space, allowing spaces to feel as if they were three times the size. These mechatronic systems need capable electronics and connected microcontrollers to bring furniture to the Internet of Things (IoT). We present these electronics and firmware for three smart robotic spaces. These smart spaces need powerful software and computing systems to enable the transformations and give magic to the space. We present software written for three smart robotic spaces. The right user interfaces are vital for rich user experience. User studies with different smart home user interfaces show that although tactile interfaces are the most reliable and easiest to work with, people are hopeful for sufficiently robust gestural and speech interfaces in future smart homes. The urban homes and offices of the future are smart, customizable, and robotic.

Tzeremes, Vasilios. "End user software product line support for smart spaces." Thesis, George Mason University, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10249280.
Full textAbstract:
Smart spaces are physical environments equipped with pervasive technology that sense and react to human activities and changes in the environment. End User Development (EUD) skills vary significantly among end users who want to design, develop and deploy software applications for their smart spaces. Typical end user development is opportunistic, requirements are usually unplanned and undocumented, applications are simplistic in nature, design is ad-hoc, reuse is limited, and software testing is typically haphazard, leading to many quality issues. On the other hand, technical end users with advanced EUD skills and domain expertise have the ability to create sophisticated software applications for smart spaces that are well designed and tested.
This research presents a systematic approach for adopting reuse in end user development for smart spaces by using Software Product Line (SPL) concepts. End User (EU) SPL Designers (who are technical end users and domain experts) design and develop EU SPLs for smart spaces whereas less technical end users derive their individual smart space applications from these SPLs. Incorporating SPL concepts in EUD for smart spaces makes it easier for novice end users to derive applications for their spaces without having to interface directly with devices, networks, programming logic, etc. End users only have to select and configure the EU SPL features needed for their space. Another benefit of this approach is that it promotes reuse. End user requirements are mapped to product line features that are realized by common, optional, and variant components available in smart spaces. Product line features and the corresponding component product line architecture can then be used to derive EU applications. Derived EU applications can then be deployed to different smart spaces, thereby avoiding end users having to create EU applications from scratch. Finally the proposed approach has the potential of improving software quality since testing will be an integral part of EU SPL process.
In particular, this research has: (a) defined a systematic approach for EU SPL Designers to design and develop EU SPLs, (b) provided an EU SPL application derivation approach to enable end users to derive software applications for their spaces, (c) designed an EU SPL meta-model to capture the underlying representation of EU SPL and derived application artifacts in terms of meta-classes and relationships that supports different EUD platforms, (d) designed and implemented an EUD development environment that supports EU SPL development and application derivation, and (e) provided a testing approach and framework for systematic testing of EU SPLs and derived applications.

Full textAbstract:
The aim of this work is to simplify access to information for citizens of the city of Brno and at the same time to innovate the way of communication between the citizen and his city. The problem is solved by creating a conversational agent - chatbot Kroko. Using artificial intelligence and a Czech language analyzer, the agent is able to understand and respond to a certain set of textual, natural language queries. The agent is available on the Messenger platform and has a knowledge base that includes data provided by the city council. After conducting an extensive user testing on a total of 76 citizens of the city, it turned out that up to 97\% of respondents like the idea of a city-oriented chatbot and can imagine using it regularly. The main finding of this work is that the general public can easily adopt and effectively use a chatbot. The results of this work motivate further development of practical applications of conversational agents.

Haglund, Kristian, and Pia Flydén. "Key determinants for user intention to adopt smart home ecosystems." Thesis, Blekinge Tekniska Högskola, Institutionen för industriell ekonomi, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:bth-16807.
Full textAbstract:
IoT is a technology where different devices are equipped with internet connection which makes it possible to control them and exchange data over internet. IoT can be thought of as an umbrella term covering a broad and ever-growing range of services and technologies. One of the segments within IoT is the smart home ecosystem. The tremendous development the last decade within smartphones, wearable devices and broadband has created new ways to connect individual devices in the home (Qasim and Abu-Shanab, 2016; Jeong et al, 2016; Wilson et al, 2017; Hubert et al, 2017). This creates a synergy effect; by connecting multiple devices to a system new value is created. Energy, home controls, security, communication and entertainment services are all included in the smart home (Miller, 2015; Wilson et al, 2017). Even though the concept of smart homes has a large potential it seems like it has not reached its full potential and the diffusion of the innovation among the consumers is still at an early stage (Balta-Ozkan et.al, 2013; Yang et.al 2017). So far, many studies have been performed on the technical aspects of IoT and smart home ecosystems but less attention has been paid on the consumer point of view and what determinants that play a role in the intention to adopt the technology (Yang, Lee, and Zo. 2017). In addition, previous studies have mainly focused of one single device and has not considered the entire ecosystem (Yang, Lee, and Zo. 2017). Therefore, the purpose with this thesis is to study what are the key determinants for the intention to adopt smart homes from an ecosystem point of view. To fulfill the purpose known theoretical models regarding intention to adopt technology have been used to develop a research model. The basis to establish the research model has been the theory of innovation adoption, TRA, TPB, TAM, VAM and UTAUT. Based on the literature four determinants were selected to be included in the model; these were cost, perceived ease of use, perceived usefulness and individualization. The first three are all included in the mentioned theoretical models and have previously been proven to be important for intention to adopt. The last one, individualization is derived from the field of product differentiation. In the literature it is mentioned that the possibility to refine, adjust and modify may be crucial for the user (Dodgson et.al. 2008). With this background it was interested to include individualization as a determinant in the research model and study how it impacts intention to adopt. In addition to the determinants one moderator was included; the composition of the household. In order to collect the empirical data a survey was conducted using the snowball sampling approach via Facebook and LinkedIn. The survey consisted of two sections where the first section aimed to collect background information about the respondent and the second section consisted of questions regarding the determinants. In the second section the respondents were asked to respond according to a 5-point Likert scale. The used questions in the survey was predefined in the literature. Study results show that consumers’ use intention is shaped by individualization, perceived usefulness and perceived ease of use. Cost was found not to be statistically significant. Neither was the composition of the household.

Full textAbstract:
Due to the current urbanization trend, people are spending more time than ever on their daily commute. However, commuting in megacities often results in irritating scenarios. Especially when using public transportation. This project tried to provide an alternative way of commuting that would allow people to refresh themselves during the journey and prepare for their activities in the best way possible. Rather than looking at the commute as a transition from A to B, this project tried to envision different scenarios of daily life and implement smart solutions that would enhance the experience through seamlessly integrated technologies—based on the technological expertise from the sponsor Huawei. In this concept, smart sensors combined with data collection would provide a tailored experience for the customer at different depth levels. The process includes brand research and topic selection to set up the design goal. Basing on the valuable material got from the first step, the design moved to the next step and tried to find the solution for the thesis topic. This is processed by gathering information from the website, brainstorming the ideation. Then the author built up the prototype by sketching, rendering, and 3D modeling. The user experience got developed basing on the robust design. The author started with user research and analyzed and set up personas. The result is an interior design concept with a particular focus on its interaction and user experience. The seating position supports the user experience by changing in harmony with individual preferences and time of the day. Three unique travel modes provide different levels of control over the overall experience based upon the user's request and their trust in the smart system.

Full textAbstract:
Smart homes are residences equipped with information and communication technologies that anticipate and respond to the needs of the occupants. Despite the numerous research and industrial efforts, today only few expensive smart homes have been built and sold. The reason behind this slow uptake is the technology-driven approach characterizing existing solutions. The doctoral Thesis aims at demonstrating that a smart home can provide functionalities designed with a user-centered approach, taking into account ergonomic considerations about domestic activity and human cognition. This is achieved in collaboration with cognitive ergonomists, which help "minding the gap" between human context and machine-understandable context. Using off-the-shelf and lightweight instrumentation (also minimizing privacy concerns), extending existing context modeling, reasoning and management tools and following the Ubiquitous Computing principles, the doctoral work led to the following achievements: (i) the inter-disciplinary design of suitable functionalities, in collaboration with cognitive ergonomists; (ii) the design of a context-aware system that captures and reasons about uncertain contextual information in a distributed fashion; (ii) the realization of a working prototype that demonstrates the provision of energy-saving and comfort-preserving functionalities.

Green, William. "Capturing user requirements for smart hometechnology, to support industry practice." Thesis, Loughborough University, 2008. https://dspace.lboro.ac.uk/2134/8135.
Full textAbstract:
The home-orientated technology industry has grown rapidly since the 1980s. This movement has been catalysed by an intensive evolution in technology development and is reflected by academic and industry interest in the area. In combination with the ubiquity of digital consumer products, such interest has driven the re-emergence of the smart home as an ideal that, with a paradigmatic shift in human interaction with their environment, will improve lifestyle and support independent living. Accordingly, the smart home has come to represent an aspirational vision of the future. However, despite the renewed interest in the area and a legacy of technology that has resulted in confused, frustrated and disillusioned users, little research has been undertaken to identify the perception of the user towards the smart home. Consequently, the provision of guidance for industry practice and designers is severely limited. To counteract technology that does not support user needs and to ensure the efficacy of the smart home, this research captures the perception of the user towards existing and future technology and reflects on the needs of state of the art industry practice. In study one, eight workshops (N=55) captured positive anticipation and attitudes of users towards the smart home but with some concerns and contradictory needs and requirements. A contextual enquiry (N=12), incorporating a probe study and home interview, explored technology usage in more depth. Differences in basic technology usage, such as heating and lighting, revealed complex meanings behind the assumed use of technology. User needs were embodied in a co-design workshop (N=8) in which prototypes for the control of their smart home were modelled. Concepts for the smart home are distinguished by functionality, the locus of control for human-system interaction, and the nature of interaction. Despite the acknowledgement of the value of perceptive and aware technology, users must perceive empowerment and ownership of all activity in the home. To explore current practice in design and development for the smart home, interviews were conducted with industry professionals (N=18) from twelve companies and analysed according to a grounded theory method with a constructionist approach. User centred design was found to be prevalent in the smart home industry but compromises remained. The user perceptions towards the smart home illustrate the challenges that the industry must overcome, and provide a case study example of including the user throughout the `fuzzy front end' of the design process. Although user centred design is often deemed a panacea in the development of successful products, this study has found that disparate views on user centred design have caused a misrepresentation of the user and their importance. It is clear that companies want to be people-centred but effective user centred design practice is seemingly not arbitrary. The most immediate needs for successful professional practice of user centred smart home design have been identified in this study and are supported with the provision of guidance that will contribute to their understanding.

Full textAbstract:
L’informatique ubiquitaire est graduellement devenue une réalité, nous utilisons divers dispositifs pour travailler et s’amuser (l’ordinateur, le portable, le smartphone). Au-delà des dispositifs personnels, les citoyens obtiennent des informations par les écrans publics qui sont présents partout dans les villes: l’abribus, l’aéroport, le centre commercial, etc. Il semble que la vision de l’informatique ubiquitaire est plus proche, cependant, l’avenir décrit par Mark Weiser est encore loin: «les technologies les plus profondes sont celles qui disparaissent». Actuellement les appareils électroniques ne sont pas assez intelligents et bien intégrés dans le contexte d’une ville. La ville intelligente (smart city) est un concept émergent pour construire une ville utilisant les technologies de l’information et de la communication (TIC). Ce concept propose d’améliorer la qualité de la vie et d’augmenter l’efficacité des activités dans une ville par les TIC. Il aussi met l’accent sur les savoir-faire des citoyens pour la construction des villes. La ville intelligente est en effet un système ubiquitaire large qui comprend différent systèmes (le système de gestion trafic, le système de transport public, le système de distribution de l’énergie, etc.). Les écrans publics construisent l’une des plus importants systèmes dans une ville. Cependant, ils ne sont utilisés que pour afficher de l’information, ils sont aveugles aux utilisateurs ainsi qu’à leurs dispositifs personnels. Dans cette thèse, nous proposons de construire des écrans publics intelligents basés sur l’interaction proxémique. L’interaction proxémique est inspirée par le terme venant de la psychologie «Proxémique». La Proxémique désigne les espaces virtuels autour des êtres humains pendant la communication. Les espaces sont différents selon la culture, les lieux où l’interaction se déroule. La Proxémique a été introduite à l’interaction homme machine par S. Greenberg en 2011 et il a créé le terme d’interaction proxémique. L’interaction proxémique étudie l’interaction en fonction de la relation spatiale entre les objets. Un écran proxémique peut connaître la distance, la position, l’identité et le mouvement de l’utilisateur. Ces dimensions proxémiques sont mesurées par l’écran comme les signaux de l’interaction implicite. Par ailleurs, il peut détecter les dispositifs mobiles des utilisateurs: il peut distribuer et échanger de l’information avec les dispositifs de l’environnement. Par rapport à un écran traditionnel, un écran proxémique offre des contenus plus personnalisés et ainsi répond aux besoins immédiats des utilisateurs. Ces avantages permettent à un écran public de bien s’adapter aux exigences de la ville intelligente. Notre objectif est d’étudier la façon de relever les défis d’un écran public dans une ville intelligente par l’interaction proxémique. Pour atteindre cet objectif, nous étudions les dimensions de l’interaction proxémique, et puis nous concevons un prototype d’écran proxémique grâce à différents capteurs: Kinect, Leapmotion et Webcam. Ce prototype supporte l’interaction implicite et explicite des utilisateurs pour fournir un contenu plus personnalisé aux utilisateurs, ainsi que des interactions naturelles. En outre, nous avons développé une boîte à outils pour la migration des données entre l’écran public et les appareils mobiles personnels. Avec cet outil, l’utilisateur peut télécharger des ressources à partir de l’écran, et l’écran deviendra un terminal pour recueillir les connaissances des citoyens pour la ville intelligente. Nous discutons les applications potentielles de ce prototype dans la ville intelligente, et nous proposons une application expérimentale qui est un panneau d’affichage proxémique des vols dans un aéroport. Basé sur cette application, nous avons réalisé des études utilisateurs systématiques dans notre laboratoire pour vérifier si l’interaction proxémique peut vraiment améliorer les performances d’un écran publicUbiquitous computing is gradually coming into reality, people use various digital devices (personal computer, laptop, tablet and smartphone) in order to study, work, entertain and communicate with each other. A city is actually a ubiquitous society, citizens get practical information from digital public displays that are installed everywhere in a city: bus station, railway station, airport or commercial center, etc. It seems that we are closing to the vision of ubiquitous computing, however, it’s still far from the vision what Mark Weiser described: the most profound technologies are those that disappear, they weave themselves into the fabric of everyday life until they are indistinguishable from it. That means in nowadays the widespread digital devices are still not intelligent enough and not well integrated, this issue is especially serious under a context of city than for personal usage condition.Smart city is a modern concept of city that seeks to improve the efficiency and quality of life by the information and communication technologies (ICTs), it as well emphasizes the importance of citizens’ knowledge for the wise management of city. The ICTs of a smart city constructs a large scale ubiquitous system, including traffic control systems, public transportation system, energy control systems, etc. In all the systems, digital public displays are one of the most important viewports that connect citizens with city. However, the public display today is only used as a screen to display information, it’s blind to the presence of users and ambient devices, these result in low efficiency of interactions, and make a city unable to take use of citizen knowledge.In this dissertation, we build an intelligent public display by the theory of proxemic interaction. Proxemic interaction is spatial related interaction patterns inspired by the psychological term: Proxemics, it studies the spatial -related interaction human to device and device to device. A proxemic interactive public display means that it is aware of user’s presence, position, movement, identity and other user related attributes, and takes these attributes as implicit inputs for interactions. Besides, it can sense ambient mobile devices and act as a hub for local deices information flows. Compared with traditional public display, proxemic interactive display can provide specific users with more personal related and instant - need information rather than provide general information to all users. That means to make displays sense users instead of making users explore displays exhaustively. These advantages make a proxemic display more adapt to the prospect of smart city.Our object is to study how to address the challenges of public display in a smart city by proxemic interaction. Towards this object, we study the dimensions of proxemic interaction, and build a prototype of proxemic interactive projected display with Kinect, Leap motion and web camera. This prototype supports implicit and explicit interaction of users to provide more personalized contents to users, as well as natural interactions. Furthermore, we developed a toolkit for data migration between public display and personal mobile devices, so that public display becomes aware of ambient users’ devices, users can download resources from public displays freely, while public displays can be as a terminal to collect knowledge of citizens for smart city.We discuss the potential applications of this prototype under smart city, and build an experimental application of proxemic airport flight information board. Based on this experimental application, we organized a systematic laboratory user study to validate whether proxemic interaction can really improve the performance of public displays

En raison de la nature intime des interactions homme-textiles (essentiellement, nous sommes entourés par les textiles 24/7 - soit sous la forme de vêtements que nous portons ou comme rembourrage dans nos voitures, maisons, bureaux, etc.), les textiles intelligents sont devenus des plates-formes de plus en plus attrayantes pour les réseaux de capteurs innovants biomédicaux, transducteurs, et des microprocesseurs dédiés à la surveillance continue de la santé. En même temps, l'approche commune dans le domaine des textiles intelligents consiste en l'adaptation de la microélectronique planaire classique à une sorte de substrat souple. Cela se traduit souvent par de mauvaises propriétés mécaniques et donc des compromis au niveau du confort et de l'acceptation des usagers, qui à leur tour peuvent probablement expliquer pourquoi ces solutions émergent rarement du laboratoire et, à l'exception de certains cas très spécifiques, ne soit pas utilisés dans la vie de tous les jours. Par ailleurs, nous assistons présentement à un changement de paradigme au niveau de l'informatique autonome classique vers le concept de calculs distribués (ou informatique en nuage). Dans ce cas, la puissance de calcul du nœud individuel ou d'un dispositif de textile intelligent est moins importante que la capacité de transmettre des données à l'Internet. Dans ce travail, je propose une nouvelle approche basée sur l'intégration de polymère, verre et métal dans des structures de fibres miniaturisées afin de réaliser des dispositifs de textiles intelligents de prochaine génération avec des fonctionnalités de niveau supérieur (comme la communication sans fil, la reconnaissance tactile, les interconnexions électriques) tout en ayant une forme minimalement envahissante. Tout d'abord, j'étudie différents modèles d'antennes compatibles avec la géométrie des fibres et des techniques de fabrication. Ensuite, je démontre expérimentalement que ces antennes en fibres multi-matériaux peuvent être intégrées dans les textiles lors d’un processus standard de fabrication de textiles. Les tests effectués sur ces textiles ont montré que, pour les scénarios «sur-corps et hors-corps», les propriétés émissives en termes de perte de retour (S11), le patron (diagramme) de radiation, l'efficacité (gain), et le taux d'erreur binaire (TEB) sont directement comparables à des solutions classiques rigides. Ces antennes sont adéquates pour les communications à courte portée des applications de communications sans fil ayant un débit de données de Mo/s (méga-octets par seconde) (via protocoles Bluetooth et IEEE 802.15.4 à la fréquence de 2,4 GHz). Des simulations numériques de taux d'absorption spécifique démontrent également le plein respect des règles de sécurité imposées par Industrie Canada pour les réseaux sans fil à proximité du corps humain. Puisque les matériaux composites de fibres métal-verre-polymère sont fabriqués en utilisant des fibres de silice creuses de diamètre submillimétrique et la technique de dépôt d'argent à l'état liquide, les éléments conducteurs sont protégés de l'environnement et ceci préserve aussi les propriétés mécaniques et esthétiques des vêtements. Cet aspect est confirmé par des essais correspondant aux normes de l'industrie du textile, l'étirement standard et des essais de flexion. De plus, appliquer des revêtements superhydrophobes (WCA = 152º, SA = 6º) permet une communication sans fil sans interruption de ces textiles sous l'application directe de l'eau, même après plusieurs cycles de lavage. Enfin, le prototype de textile intelligent fabriqué interagit avec l'utilisateur à travers un détecteur tactile et transmet les données tactiles à travers le protocole Bluetooth à un smartphone. Cette démonstration valide l’approche des fibres multi-matériaux pour une variété d'applications.As we are surrounded by textiles 24/7, either in the form of garments that we wear or as upholstery in our cars, homes, offices, etc., textiles are especially attractive platforms for arrays of innovative biomedical sensors, transducers, and microprocessors dedicated, among other applications, to continuous health monitoring. In the same time, the common approach in the field of smart textiles consists in adaptation of conventional planar microelectronics to some kind of flexible substrate, which often results in poor mechanical properties and thus compromises wearing comfort and complicates garment care, which results in low user acceptance. This explains why such solutions rarely emerge from the lab and, with the exception of some very specific cases, cannot be seen in the everyday life. Furthermore, we are currently witnessing a global shift from classical standalone computing to the concept of distributed computation (e.g. so-called thin clients and cloud storage). In this context, the computation power of the individual node or smart textile device in this case, becomes progressively less important than the ability to relay data to the Internet. In this work, I propose a novel approach based on the idea of integration of polymer, glass and metal into miniaturized fiber structures in order to achieve next-generation smart textile devices with higher-level functionalities, such as wireless communication, touch recognition, electrical interconnects, with minimally-invasive attributes. First, I investigate different possible fiber-shaped antenna designs and fabrication techniques. Next, I experimentally demonstrate that such multi-material fiber antennas can be integrated into textiles during standard textile manufacturing process. Tests conducted on these textiles have shown that, for on-body and off-body scenarios, the emissive properties in terms of return loss (S11), radiation pattern, efficiency (gain), and bit-error rate (BER) are directly comparable to classic ‘rigid’ solutions and adequately address short-range wireless communications applications at Mbps data-rates (via Bluetooth and IEEE 802.15.4 protocols at 2.4 GHz frequency). Numerical simulations of the specific absorption rate (SAR) also demonstrate full compliance with safety regulations imposed by Industry Canada for wireless body area network devices. Since metal-glass-polymer fiber composites were fabricated using sub-millimetre hollow-core silica fibers and liquid state silver deposition technique, the conductor elements are shielded against the environment and preserve the mechanical and cosmetic properties of the garments. This is confirmed by the textile industry standard stretching and bending tests. Additionally, applied superhydrophobic coatings (WCA=152º, SA=6º) allow uninterrupted wireless communication of the textiles under direct water application even after multiple washing cycles. Finally, I fabricated a user-interactive and wireless-communicating smart textile prototype, that interacts with the user through capacitive touch-sensing and relays the touch data through Bluetooth protocol to a smartphone. This demonstration validates that the proposed approach based on multi-material fibers is suitable for applications to sensor fabrics and bio-sensing textiles connected in real time to mobile communications infrastructures, suitable for a variety of health and life science applications.

Full textAbstract:
Smart Video erbjuder som dotterbolag till Codemill sina kunder möjligheten att, med hjälp av verktyget Creative Tools, omvandla deras videoklipp till interaktiva internet-butiker. Genom att integrera länkar i klippen så ökar antalet produktklick upp till tio gånger, i jämförelse med alternativet där länkarna är listade i anknytning till videon. Det ständigt växande internetanvändandet gör att efterfrågan på nya och innovativa mjukvarulösningar hela tiden ökar. Detta medför i sin tur att företag som Smart Video strävar efter att lansera sina produkter på marknaden så fort som möjligt, ofta genom att arbeta på ett sätt som skulle kunna beskrivas som ”trial-and-error”. Något som resulterar i utvecklingsprocesser med ett förhållandevis lågt användardeltagande och, i förlängningen, den förlorade konkurrensfördelen som ett användar-centrerat arbetssätt kan ge. Det här examensarbetet ämnar därför undersöka vikten av att inkludera användaren i de tidiga skedena av mjukvaruutvecklingsprocessen samt föreslå metoder som anses lämpliga vid utformningen av det koncept som är tänkt att rikta sig till de kunder som önskar Smart Video som en tjänst. Det huvudsakliga målet är att i slutet av projektet presentera ett konceptförslag som besparar kunden arbetet att själv omvandla dessa videoklipp till interaktiva motsvarigheter samtidigt som de, som en del utav en god användarupplevelse, har fortsatt kontroll över utförandet. Genom intervjuer, fokusgrupper och andra mindre metoder som studerar de tre användargrupperna; kund, operatör och utvecklare, utvecklas en stor förståelse för vad som är viktigt för tjänsten, från vilken konceptutformningen kan utgå. En utformning som till största del går ut på att iterativt formge det internetbaserade användargränssnitt som anses vara den enskilt viktigaste delen utav tjänsten. Användbarhetstester och omfattande åsiktsinsamling verifierar gränssnittet och det kan således i slutet av projektet, tillsammans med resten av konceptet, presenteras som ett förslag på hur Smart Video kan gå till väga för att fortsätta vara aktuell för sina kunder.The Codemill affiliate Smart Video provides their customers with the tool they need to transform their videos into interactive online stores. By “smartifying” the videos and adding links to products or services adjacent to the video itself, the click rate increases by up to ten times. As internet usage and online purchases grows larger, so does the demand of software that surround this phenomenon. This in turn makes companies, similar to Smart Video, strive to launch their product to the market as fast as possible by using a development process that could be described as “trial-and-error”. This results in drawbacks on the amount of performed user studies and losses in potential competitive advantages that a more user focused research might give. This thesis examines the importance of including users in the early software development phases and then suggests appropriate user study methods to the design of a concept for those customers that requires Smart Video as a service. With the main goal to present a design suggestion that spares the customer the process of modifying the material themselves, while maintaining in control of the end result and engaged in a satisfying user experience. By conducting interviews, focus groups and other minor user involvement methods with the three user groups, a great understanding of what was important in the service was gained. As it formed a base from which the design process could proceed. With the iterative procedure of constructing the customer interface prominent, the service took shape as it dealt with the issues and opportunities gathered. The usability test and the extensive feedback on the prototype justified the look of the interface and its usability, when it at the end of the semester, together with the rest of the concept, was presented as a proposal on how to approach the idea of taking that next Smart Video-step, thus making it a more attractive and relevant actor.

This master project focuses on the development of a front-end applicationfor cloud computing. Traditionally, televisions have been excluded from thealways connected world. With the appearance of the smart televisions it isnow possible to connect them to the Internet. However, there still exists agap between televisions and services in the cloud.To solve the problem,we have developed a JavaScript application. This application allows the user to log into their CloudMe account from a SamsungSmartTV with multimedia support. This application is centered on improving the responsiveness performance of a cloud computing application. It alsoenhances the user experience by creating a user-friendly UI for a television.During the course of this thesis, the application and its functionalities havebeen studied, designed, developed, optimized and finally tested. We havealso done a set of measurements to validate the responsiveness of the proposed design.The development of this TV application shows the TV is a potential targetdevice for cloud computing services due to its better resources and capabilities in di↵erent areas such as multimedia reproduction.

In a world where there are about 7 billion people living and this number is continuously increasing, it is necessary to reduce the resource consumption to achieve a sustainable situation. In this work, a system to detect water and electricity consumption is introduced to identify resource waste and inform the consumers about it. For this purpose, many sensors are deployed in the kitchen of the department in order to gather data of the consumption. These sensors are an alternative to other ways of getting this information that are usually considered as invasive, like a camera. Even though, as far as there are many sensors deployed, the way to put all data together will be using wireless communication. Then, a treatment is performed in order to obtain some statistics about the consumption. These networks can also be accessed by people external to the department, who would be able to get information about their consumption and, consequently, their expenditures. Because all of this, a privacy problem of the enterprise appears, in this case the Electrical Engineering Automatic Control Department. Regarding the wireless communication, dierent protocols will be tested to check their reliability. Furthermore, the data from the dierent sensors makes possible to determine behaviour patterns of the people working there. By using this system, not environmentally friendly actions that lead to resource waste can be easily identied and corrected. Again, this opens a discussion about privacy, concerning the dierent people and their habits. To sum up, the system would enable the consumers to decrease their resource consumption, which would lead to an important energy saving in large scale and a reduction in costs in small scale.

The maturity of smart home technologies and wireless capabilities, increased accessibility through mass-market availability of internet is making the feasibility of the smart home more realistic. The added incentives to better control utilities and communications to make lives more sustainable, has also driven the growth in the market. This thesis investigates the advantages of the smart home both for the environment and user. Outlining opportunities for business by finding gaps in the market is to better synthesise products and services to improve the user experience. A literature review, market research and ethnographic research was undertaken to understand the current state of the smart home industry and identify the main stakeholders that impact the user. A customer journey map was created to visualise the user process and highlighted problem areas. A survey showed users were most concerned about quality, functions and saving energy and money. The survey perceptions on interactions with technology also shed light into the necessity for robust and reliable technology and adaptable products and services. The final outcome is a prototype model to improve user experience, including stakeholder influence, user needs and the connections between different stakeholders from pre-sale, sale and after-sale.

Syftet med denna studie har varit att närmare studera användarnas roll vid planering, utveckling och användande av smarta elnät, vad man kan dra för lärdomar av pågående projekt inom utvecklingen av smarta elnät när det kommer till användarnas roll i projekten, samt ge rekommendationer för ett framtida arbete. Detta gjordes genom en fallstudie av två sammanhängande projekt inom en kommun i Sverige som för närvarande arbetar med smart stadsutveckling och smarta elnät. Empiriinsamling skedde med hjälp intervjuer av boende och ansvariga i projektet samt projektdokumentation. Resultatet visar att de boendes roll i planeringen av projektet inte var stor, och att de inte räknades in bland de viktiga intressenter som enligt rekommendationer skulle vara delaktiga i projektet. Vidare skedde användarmedverkan i en begränsad form vid utvecklingen av den teknik som skulle användas hemma hos de boende, och då främst i form av användartester efter det att systemen hade tagits fram. Vidare visade intervjuerna på ett bristande engagemang hos användarna när det kommer till att använda tekniken som finns tillgängliga i det smarta nät som utvecklats inom kommunen. Dessa resultat utgör viktiga lärdomar för framtida projekt. Rekommendationerna som togs fram för ett framtida arbete inom smarta elnät är främst att det bör ske en ökad involvering av användare under samtliga delar i projekt rörande smarta elnät för att säkerställa en relevant och demokratisk samhällsutveckling och att detta bör ingå i projektens målsättningar. Vidare bör framtida projekt undersöka möjligheterna med att studera och arbeta med sociala praktiker inom energianvändning, för att undersöka hur man kan skapa en övertygelse hos de boende som leder till en ökad vilja att spara energi, och utnyttja de tekniska verktyg som gör detta möjligt. Det krävs även arbete för att hitta ytterligare incitament till aktiv energibesparing för att optimal användning av de smarta näten ska kunna uppnås.Smarta elnät och tjänsteutveckling för hemmet – vem är i behov av en smartare vardag?

Full textAbstract:
Newer technologies are being developed all the time in order to help us in our daily tasks. Smart Assistant (SA) is one such broad category of devices which, when instructed through speech or command, perform certain tasks. Most SAs have two primary tasks: identify the user, and perform the taskcommunicated by the user. The task of identification can be achieved in severalways and one such method involves face recognition interface integrated within SA. Further interaction with the user is achieved via either a touch screen or a speech-based interface integrated within SA. Since the primary objective of a SA involves interaction with an individual user, it is necessary to identify users' concerns related to the usability of SA.In this thesis, the goal is to perform a usability study of Smart Assistant(SA) in the context of providing assistance in scheduling meetings at the workplace. Adopting a qualitative approach and we performed the usability study by designing a questionnaire to document public perception of new technologies like a smart assistant. We performed an online survey and collected responses from a section of the population. We also performed a similar survey with employees at Cybercom who have experience in interacting with the SAbeing developed in their company, and which is meant for providing assistance in scheduling meetings.In the process, we also provide relevant background literatureon human-computer interaction to contextualize the results of our survey. Themain outcome of this work is a list of guidelines to be followed for developing asocially interactive speech-based SA.The results of our survey indicate that there are several privacy and security related concerns that users have when using a face recognition interface and speech-based interaction. Although some of the concerns require technological advancements, a few of the concerns can be addressed by adopting certain suggested strategies.

Full textAbstract:
This thesis presents the Simple Internet of Things Enabler (SITE), a smart home solution that allows users to specify and centrally control IoT smart objects. Unlike most existing systems, SITE supports End-User Development (EUD). It includes features that make the system accessible to users that do not possess a background in Information Technology (IT). Hence, it defines a simple language for the specification of control rules for smart objects. It also provides a user interface to graphically illustrate data received from smart objects.
Furthermore, we present the SITE architecture and describe the components that enable users to define, register, and operate smart objects within a smart home environment. Since deploying applications on the cloud renders many advantages pertaining to data security, robustness, and elasticity of resources, we additionally propose a cloud-based architecture for SITE. In this case, SITE acts as a service hosted on a cloud platform that realizes monitoring and control of a smart home remotely.
Moreover, since most of the objects in any environment are not inherently smart, we propose a framework that affords “everyday” objects the necessary modules to measure and report their state. Hence, users realize the smart objects using a transducer network framework that supports the amalgamation of multiple transducers into a single smart object. To make these objects easily reconfigurable, we apply a plug and play mechanism to enable the clustering of any number of transducers. We propose an algorithm that dynamically detects added and removed transducers from a smart object.
To assess the usability of SITE, we conduct an empirical study involving 20 participants belonging to two user groups: users with technical training (IT users) and users without technical training (Non-IT users). We demonstrate that both user groups can satisfactorily build smart objects and define control rules in a smart home environment using SITE.

En años recientes,la Inteligencia Artificial ha contribuido a resolver problemas encontrados en el desempeño de las tareas de unidades informáticas, tanto si las computadoras están distribuidas para interactuar entre ellas o en cualquier entorno (Inteligencia Artificial Distribuida). Las Tecnologías de la Información permiten la creación de soluciones novedosas para problemas específicos mediante la aplicación de los hallazgos en diversas áreas de investigación. Nuestro trabajo está dirigido a la creación de modelos de usuario mediante un enfoque multidisciplinario en los cuales se emplean los principios de la psicología, inteligencia artificial distribuida, y el aprendizaje automático para crear modelos de usuario en entornos abiertos; uno de estos es la Inteligencia Ambiental basada en Modelos de Usuario con funciones de aprendizaje incremental y distribuido (conocidos como Smart User Model). Basándonos en estos modelos de usuario, dirigimos esta investigación a la adquisición de características del usuario importantes y que determinan la escala de valores dominantes de este en aquellos temas en los cuales está más interesado, desarrollando una metodología para obtener la Escala de Valores Humanos del usuario con respecto a sus características objetivas, subjetivas y emocionales (particularmente en Sistemas de Recomendación).Una de las áreas que ha sido poco investigada es la inclusión de la escala de valores humanos en los sistemas de información. Un Sistema de Recomendación, Modelo de usuario o Sistemas de Información, solo toman en cuenta las preferencias y emociones del usuario [Velásquez, 1996, 1997; Goldspink, 2000; Conte and Paolucci, 2001; Urban and Schmidt, 2001; Dal Forno and Merlone, 2001, 2002; Berkovsky et al., 2007c]. Por lo tanto, el principal enfoque de nuestra investigación está basado en la creación de una metodología que permita la generación de una escala de valores humanos para el usuario desde el modelo de usuario. Presentamos resultados obtenidos de un estudio de casos utilizando las características objetivas, subjetivas y emocionales en las áreas de servicios bancarios y de restaurantes donde la metodología propuesta en esta investigación fue puesta a prueba.En esta tesis, las principales contribuciones son: El desarrollo de una metodología que, dado un modelo de usuario con atributos objetivos, subjetivos y emocionales, se obtenga la Escala de Valores Humanos del usuario. La metodología propuesta está basada en el uso de aplicaciones ya existentes, donde todas las conexiones entre usuarios, agentes y dominios que se caracterizan por estas particularidades y atributos; por lo tanto, no se requiere de un esfuerzo extra por parte del usuario.Information Technology enables new solutions to be created for specific problems by applying knowledge gained in various areas of research.Our work is aimed at creating user models using a multi-disciplinary approach in which we use principles of psychology, distributed artificial intelligence, and automatic learning to create user models in open environments; such as Environmental Intelligence based on User Models with functions of incremental and distributed learning (known as Smart User Models). Based on these user models, we aimed this research at acquiring user characteristics that are not trivial and that determine the user's scale of dominant values in the matters in which he/she is most interested, and developing a methodology for extracting the Human Values Scale of the user with regard to his/her objective, subjective, and emotional attributes (particularly in the Recommender Systems). One of the areas that have been little researched is the inclusion of the human values scale in information systems. A Recommender System, User Models, and Systems Information only takes into account the preferences and emotions of the user [Velásquez, 1996, 1997; Goldspink, 2000; Conte and Paolucci, 2001; Urban and Schmidt, 2001; Dal Forno and Merlone, 2001, 2002; Berkovsky et al., 2007c]. Therefore, the main approach of our research is based on creating a methodology that permits the generation of the human values scale of the user from the user model. We present results obtained from a case study using the objective, subjective, and emotional attributes in the banking and restaurant domains, where the methodology proposed in this research was tested. In this thesis, the main contributions are: To develop a methodology that, given a user model with objective, subjective and emotional attributes, obtains the user's Human Values Scale. The methodology proposed is based on the use of existing applications, where there are connections between users, agents, and domains that are characterised by their features and attributes; therefore, no extra effort is required by the user.

Smarta enheter blir allt vanligare och teknologierna de använder blir allt mer avancerade. Som en följd av detta uppstår bekväma och effektiva lösningar till vardagliga problem. En stor mängd sammankopplade smarta enheter leder dock till system som är svåra att förstå och att använda. Detta ställer krav på lösningar som hjälper användare att interagera med enheter på ett intuitivt och effektivt sätt. En teknik som under de senaste åren blivit allt mer kommersiellt brukbar och som kan användas i detta syfte är augmented reality. Vidare så är spårning av ögonpositioner ett lovande tillvägagångssätt för att navigera virtuella menyer.Denna uppsats har som syfte att utvärdera hur ögon- och huvudrörelser kan kombineras för att låta användare på ett intuitivt sätt interagera med ett gränssnitt i augmented reality. För att uppnå detta tas två interaktionsmetoder fram som använder ögon- och huvudrörelser på något olika sätt. För att utvärdera deras prestanda och användbarhet så utförs ett experiment där deltagarna navigerar en uppsättning menyer både med hjälp av de framtagna metoderna och en beprövad referensmetod.Resultaten från experimentet visar att referensmetoden både är den snabbaste och den minst felbenägna ut av de tre utvärderade metoderna. Trots detta så föredrar deltagarna en av de framtagna metoderna, och båda dessa metoder uppnår adekvata resultat. Vidare så visar den kvantitativa datan inte på några mätbara skillnader mellan de framtagna metoderna. Däremot så uppnår en av dem högre resultat i de subjektiva utvärderingarna.Smart devices are becoming increasingly common and technologically advanced. As aresult, convenient and effective approaches to everyday problems are emerging. However,a large amount of interconnected devices result in systems that are difficult to understandand use. This necessitates solutions that help users interact with their devices in anintuitive and effective way. One such possible solution is augmented reality, which hasbecome a viable commercial technology in recent years. Furthermore, tracking the positionof users’ eyes to navigate virtual menus is a promising approach that allows for interestinginteraction techniques.In this thesis, we explore how eye and head movements can be combined in an effortto provide intuitive input to an augmented reality user interface. Two novel interactiontechniques that combine these modalities slightly differently are developed. To evaluatetheir performance and usability, an experiment is conducted in which the participantsnavigate a set of menus using both our proposed techniques and a baseline technique.The results of the experiment show that out of the three evaluated techniques, thebaseline is both the fastest and the least error-prone. However, participants prefer oneof the proposed techniques over the baseline, and both of these techniques perform adequately.Furthermore, the quantitative data shows no measurable differences betweenthe proposed techniques, although one of them receives a higher score in the subjectiveevaluations.

Full textAbstract:
As a result of developments, domestic usage of smart appliances by homeowners is increasing drastically. Clustering these appliances together and making them function as an efficient system defines a new place to live or new way of living called a “smart home”. While a smart home provides comfort to homeowners, realizing a smart home involves many technical and business oriented hurdles to be crossed. The primary goal of this thesis work is to design and evaluate the design of a residential gateway. This gateway should be designed as a standardized, secure, open source, hardware independent, and interoperable Residential Gateway. A service-oriented architecture is proposed using the OSGi framework to design the residential gateway and its individual components. These components include an access control component for homeowner authorization, a resource management component for managing connected devices, an automation component to realize an automation service, and finally a context component to provide context aware services to the homeowner. The final design proposed tries to solve the issues faced by some automation systems that are available in market. The evaluation of the design includes whether the design satisfies the basic requirements for a home gateway. This is followed by a comparison with existing systems with an emphasis on the improved features. The components proposed in the design could be used to construct a residential gateway that supports multiple services and multiple users. The proposed design will be taken into consideration during the design of Acreo’s home automation system.Som en följd av utvecklingen inom vetenskap och teknik så har användningen av smarta lösningar i hushållen ökat drastiskt. Att samla dessa apparater och få dem att fungera tillsammans som ett effektivt system, skapar ett nytt hem och ett nytt sätt att leva: ett smart hem. Å ena sidan så ger smartare lösningar ett bekvämare boende, men å andra sidan innebär det också många tekniska och affärsinriktade hinder att ta sig över. Det primära målet med denna avhandling är att utforma en bostadsgateway som är att utforma en standardiserad, säker, open source, maskinvaruoberoende, interoperabel Residential Gateway. En serviceorienterad arkitektur föreslås med hjälp av OSGi-ramverket för utformning av bostadsgateway-komponenter. Komponenterna innefattar behörighetskontroll för husägare för tillgångskontroll, resurshanteringskomponenter för hantering av anslutna enheter, automationskomponent för att inkludera automationstjänst och slutligen kontextkomponent för att tillhandahålla kontextbevakad tjänster till husägaren. Den slutliga designen som föreslås försöker lösa de problem som vissa automationssystem som finns på marknaden står inför. Utvärderingen av konstruktionen med grundläggande krav för att bygga hemgateways och med befintliga system ger information om de improviserade funktionerna. De komponenter som föreslås i konstruktionen kan användas för att bygga en bostadsgateway som stöder flera tjänster och flera användare.

This master thesis project studies behavior and actions of older users in China, with emphasis on the influence of vision decrease on older peopleʼs using experience. Related data was collected through the action research process and user behavior was studied. The project can be divided into two parts: user study and action research. In the user study section, user problems were posed and studied thoroughly with three user investigation methods: questionnaire, interview and ethnographic observation. Analysis was then carried out according to the study outcomes. Based on the user study results, action research direction was elicited to mainly focus on three aspects: font and icon study, as well as touch-screen interaction pattern research. Contextual inquiry was adopted as the primary research method; “Text-in-screen” prototype; “Look and feel” prototype and the platform iOS were used as tools to complete the research. At the end, explicit criteria of fonts and icons that better suits older users with poor vision was established and usersʼ adaptability for touch-screen smart phone system was explored.

This thesis presents IntuiSec, a framework for intuitive user interaction with Smart Home security. The design approach of IntuiSec is to introduce a layer of indirection between user-level intent and the system-level security infrastructure. This layer is implemented by a collection of distributed middleware and user-level tools. It encapsulates system-level security events and exposes only concepts and real-world metaphors that are intuitive to non-expert users. It also translates user intent to the appropriate system-level security actions. The IntuiSec framework presents the user with intuitive steps for setting up a secure home network, establishing trusted relationships between devices, and granting temporal, selective access for both home occupants and visitors to devices within the home. The middleware exposes APIs that allow other applications to present the user with meaningful visualizations of security-related parameters and concepts. I present the IntuiSec system design and an example proof-of-concept implementation, which demonstrates the user experience and provides more insight into the framework.

This study applied a radio frequency identification (RFID) reader module and an Arduino development board to turn on smart outlet power supplies using RFID. A current transformer integrated with an energy chip captured the current within the equipment, and a dsPIC30F4011 digital signal controller regulated the total current. Using sequential or random overcurrent power-down modes, we controlled the total current provided by the smart outlet within ratings. Furthermore, an LCD displayed the current in the equipment during operation for user reference.

The earpiece has become an indispensable part of our daily life. It provides not only sound output but also supports simple input right now. However, the interaction with the smart earpiece has been constrained due to its small form. In the aim of extending the ear-input space and interaction method, we explored the user-defined gestures with smart earpiece through the elicitation study. We recruited 28 participants, each designing gestures for 31 smart device-related tasks. With a total of 868 gestures, we conducted a gesture taxonomy and analyzed participants' mental models. Based on our classification, we proposed a user-defined gesture set and provided several insights for designing ear-input gestures. First, the users preferred choosing different interactions according to tasks, not focused on only mid-air gestures or touch-based gestures. Second, similar gestures were assigned to seemingly related tasks for better understanding and easier to remember. In addition, users preferred fewer fingers used and small size gestures when they concerned with social acceptance.

Information communication technology has been incorporated into healthcare services for years. As the technology evolves, internet of things introduces new opportunities for constructing smart hospitals. It is important to explore the users’ requirement during early stage of development. Along with the growing numbers of disabilities and elderly, the need for rehabilitation and long-term care rises. The current research focused on the rehabilitation wards because of the possibilities of extension of the designs from hospitals to communities as the basis of telerehabilitation. We used service blueprinting, in-depth interviewing and Analytic Hierarchy Process to explore the users’ requirement of smart hospitals from the prospective of clinical workers in rehabilitation wards of a medical center. As the results, we 1) completed a service blueprinting for in-patient rehabilitation; 2) explored the unmet needs during clinical works by in-depth interviewing senior workers; 3) summarized the requirement domains during clinical works; 4) ranked the requirement domains by Analytic Hierarchy Process. Our results also showed the highest ranked requirements as clinical alerts and evaluation/recording. The different rankings of requirements among workers of different professions reflected the need of accommodation and customarization. The above findings would provide useful insights into clinical workers’ requirements for future system designs.

In the decades, the cryptosystem becomes more and more complex to enhance the security with raise of the computation loading and cost. In the beginning, the cryptosystem adopted the concept of the public-key-based cryptosystem. However, the computation takes lots of time and may not be available in the particular scenario, like mobile environments. In mobile environments, the computation ability of the mobile device may be limited too low to execute the high computation loading, like the public-key-based cryptosystem. Thus, the hash-function-based cryptosystem is introduced to decrease the computation loading without losing security. Nowadays, the hash-function-based concept is the trend in the cryptosystem. Generally speaking, simple to use and easy to implement are practical. According to this idea, we proposed two kinds of user identification schemes. In the two schemes, the password-based authentication and the temper-resistant devices are introduced to provide the service of secure communication in this thesis. In the first scheme, we try to formally model the general user identification scheme and adversarial attack. Based on the first scheme, we proposed the second scheme in which there are mutual authentication and session key agreement to enhance the security. Because of the integrity of hash function, we adopted the hash function in both user identification schemes and several improvements are hence earned.

With the rapid development of computer network technologies, users can easily access remote servers’ resources over public but insecure channels anytime anywhere. When accessing remote services over distributed networks, user authentication plays an important role to prevent resources or services from being accessed by unauthorized users. For personal privacy, it is essential to protect the user’s identity because user anonymity has received much attention in recent year. Therefore, many user authentication schemes using smart cards have been proposed to solve the issue of user anonymity while achieving mutual authentication and key agreement. However, most of them are vulnerable to some security threats because they do not thoroughly consider the security concerns. In this thesis, there are two main subjects. First, we discuss characteristics and requirements of smart-card-based user authentication schemes preserving user anonymity and propose an improvement of Wang et al.’s scheme. In addition, more and more applications are implemented in multi-server environment because computer network technologies have grown spectacularly. Thereupon, we propose a robust and novel dynamic-ID-based authentication scheme ensuring user anonymity for multi-server environment using smart cards. The proposed schemes not only comply with all security requirements but also suit applications in the resource-limited devices while preserving user anonymity.

This dissertation is addressing the smart city concept through identifying citizen participation
as an essential part of the framework.
Several smart city examples were analyzed and a high variety, not only in terms of affected
areas, but also concerning the multiple ways how individual programs integrate citizens, was
recognized. Three ways to participate in a smart city were identified:
1. Citizens help the government collecting data
2. Citizens being involved in using the data generated by the government
3. Citizens being involved in government activities.
Through elaborating on the smart city concept, the presence and importance of citizen
engagement was clarified. Further, participation itself was put into focus. Therefore, several
subject-related topics were explored and the identified participation methods were specified.
Furthermore, quantitative research was conducted in form of a survey, examining the key
findings of the literature review. To facilitate the allocation of trends to several groups, a
cluster analysis has been conducted and five clusters could be created:
The “Creatives”, -“Alternatives”, -“Techies”, -“Greens” and -“Normals”.
Major research results were:
The majority associates a smart city with a rather technical nature.
Privacy is standing out as the main concern.
Respondents are the least confident about developing an application or a service.
Combining those results with the key findings based on the literature review, the urge for city
administrations to modernize and to embrace the smart city concept was identified. The
dissertation concludes with recommending governments to overcome those barriers by the
implementation of so-called “living-labs” and “toolkits”.

With the application of rapid development of digital technology and multimedia technology, the applications and functions of traditional TV is increasing. Information communication is transformed from one-way receiving into two-way exchange, through the integration of state-of-the-art hardware and software. This allows TV to be implemented with network capabilities and independent operating system, which is known as “Smart TV”. However, the market research organization NPD surveyed on December of 2012 indicated that only less than 15% of smart TV users could use new TV functions such as downloading applications or browsing websites. Many smart TV consumers indicats that current problem is mainly arising from inconvenient remote control. Therefore, this study aims to use experimental observation, performance and subjective measurements to investigate the usability of traditional remote control, motion sensing (or remote point) control and touch control, and finally to provide suggestions for smart TV remote control and interface design. The main findings of this study are as blow. Statistically significant differences of the operating modes between three different remote control types are found. For traditional TV features, traditional remote control performs better than the others. For new smart TV features, motion control''s performance is better than the others. Overall, the usability of three types of remote controls are not rated only at “OK” level. The results also provide smart TV remote control design recommendations as follows: (1) Intuitive and simple operations. (2) Avoid using composite keys/buttons. (3) Grouping buttons according to different functions/scenario. (4) Clear and recognizable icon design and words marked. (5) Provide one-hand control mode to reduce physical loadings. (6) No need to look down at the remote control. (7) Universal concerns at all ages.

The ideas of smart home and home automation have been proposed for many years. However, when discussing homes of the future, related studies have usually focused on deploying various smart appliances (or devices) within a home environment and employing those appliances automatically by pre-defined procedures. The issue of user-configurable home automation has largely been neglected recently. The difficulties of supporting user-configurable automation are due to the complexity of various dynamic home environments. Within their home domains, users usually think semantically; for example, “I want to turn off all the lights on the second floor”. If a home automation system cannot accept semantic commands or provide semantic feedback, users may have to create multiple processes for one task and modify them frequently. This thesis proposes a semantic home automation system, USHAS (User-configurable Semantic Home Automation System), which adopts Web Service and WSBPEL for executing automated process; OWL and OWL-S for defining home environments and service ontology; and a self-defined markup language, SHPL (Semantic Home Process Language), for describing semantic processes. To provide convenient and friendly user interface, USHAS allows users to define their home environments and automation processes via Web pages. In this manner, users can access USHAS and control appliances not only on their PCs but also on their mobile devices. Moreover, USHAS is also able to play the role of home information broker. USHAS can provide the capability of offline browsing and executing the user-selected Web pages and Web applications on PCs and mobile devices.

Recently, several password authentication schemes using smart card have been proposed by many scholars. In a password authentication scheme using smart card, a legal user can login to a remote server and access the authorized data. In 1981, Lamport proposed a remote authentication scheme for insecure communication. The scheme needs a password table on the remote server for verifying a legal user. In 1999, Hwang and Li proposed a new authentication scheme using a smart card. The advantage of the scheme is that it does not need any password table or verification table. Later, Sun proposed another remote user authentication scheme using a smart card to improve the efficiency of the Hwang-Li scheme. But these schemes do not allow users to freely choose and change their passwords. In 2003, Wu and Chieu proposed a user friendly remote authentication scheme with a smart card. Users can freely choose and change their passwords in the Wu-Chieu scheme. However, we will point out that the Wu-Chieu scheme is insecure and an improved scheme will be given. In addition, several password authentication schemes have been proposed by many scholars. In 2000, Peyravian and Zunic proposed a scheme for protecting passwords while being transmitted and changed over insecure networks. Their scheme is based on the collision-resistant hash function, which is simple and efficient to implement. Later, Lee et al. pointed out that Peyravian-Zunic scheme was insecure and proposed an improved scheme, called LLH scheme, to solve the security problem of guessing attack in the Peyravian-Zunic scheme. However, in 2003, Yoo, Ryu and Yoo have pointed out that LLH scheme is insecure and proposed a secure use authentication scheme. In this paper, we discuss that the scheme of Yoo, Ryu and Yoo has several security problems: the scheme is still vulnerable to the guessing attack, stolen-verifier attack, server spoofing attack and denial of service attack.

Due to the rapid development of the distributed network environment, the traditional password authentication scheme is no longer suitable for remote user authentication. In this thesis, we proposed different remote user authentication schemes based on RSA and ElGamal’s public key cryptosystem respectively. We utilize smart cards to be the stored and verified medium where they are often used in non-interactive remote user authentication schemes. In our proposed schemes, we also guard against many intentional attacks and consider many security issues such as replay attack, impersonation attack and so on. Furthermore, we also analyze and compare with recent researches related to smart card-based remote user authentication schemes. Compared with other schemes, our proposed schemes possess many advantages. For examples, we don’t need to maintain password table in the remote system, we can against replay attack. Furthermore, we take the functionality of user friendly into account. That is, users can select their favorite passwords and change their passwords freely.

Smart card, also called IC card or chip card, was first invented by the German scientists Jurgen Dethloff and Helmut Grotrupp, who added the identity card with integrated circuits and obtained a patent in the same year. In 1975, the French company CII-Honeywell Bull produced the first credit card that was like ID card. In the same year, French scientists Roland Moreno obtained the patent of IC card in French. In 1976, the French computer company Bull produced the products of IC card first and began to apply in various areas, just like E-purse, IC debit card, credit card, easy card, national health insurance IC card, natural person''s evidence and so on. Since the data of smart card will transmit over the Internet, there are some problems to cope with. For example, the transmission of data channels is unsafe; it is easy to be monitored or intercepted the user’s data by the attacker or to perform some of the Internet attacks, like replay attack, masquerade attack, man-in-the-middle attack, and so on. Furthermore, the data stored in smart card can be retrieved by the attacker to launch other attacks, resulting unsafe transactions. Although many scholars proposed their method to improve the security of authentication schemes, there are some weaknesses found by other scholars. Hence, improvements of security of authentication schemes become an endless cycle. In this thesis, we propose an authentication scheme to improve other methods proposed by other scholars. We assume that the data stored in smart card can be obtained by the attacker, and our scheme can resist various attacks.

With the rapid development of science and technology, smart TV gradually towards the mature stage of development and provide a variety of intelligent functions. However, when the functions of smart TV are added, buttons of the controller will also be increased. People consider that Smart TV controller becomes more complex than before, and it affects peoples willingness to use new functions. Eye-controlled devices have been regarded as expensive medical assistive devices in the past. However, gaze input has become increasingly popular and being used in various fields as a new interaction. Therefore, this research would apply the gaze input to operate the smart TV, and try to improve the user experience. Through the literature to understand the status of smart TV development, smart TV operation methods, and the eye-controlled interaction development, the eye-controlled application and existing problems. To analyze the future development possibilities of gaze input operation. By the experiment performance and the user subjective assessment. The paper probed into three modes of operation: "hand operation", "eye-hand operation" and "pure eye operation". The results showed that there were significant differences in the performance of different modes of operation. In the traditional basic function of the task, "hand operation" performance was better. On the other hand, in the new function of the task, "eye-hand operation" was better. The mental load of "eye-hand operation" was less than "pure eye operation". The highest SUS score was "eye-hand operation", followed by the "pure eye operation", "hand operation" SUS score was the lowest. But the SUS score of the three did not meet the standard of good use. In addition, the experimental results showed that the interface design has a considerable impact on eye control operations of usability. Based on the experimental analysis results, this study summarizes the gaze input operation and interface design recommendations as follows: (1) The gaze input operation should be simple and intuitive and can be personalized adjustment. (2) Buttons of the eye-controlled interface should be place the middle of the screen, and maintain the appropriate distance, also according to its functional category group arrangement. (3) To avoid using pure monochrome as the interface background. (4) Buttons should be provided obvious trigger feedback when operating.

With the development of the Internet, more and more services have been published and make life more convenient. However, it probably has a chance for malicious attackers to mount various attacks. Hence, it is essential to propose a well-designed secure authentication scheme which allows authorized users to access services from servers. In past years, because the smart card has the ability in identifying and data processing with low cost, it is widely for using in practical applications. In this thesis, we propose two mechanisms of multi-server remote user authentication using smart card in network environments. In the first study, we find the security weaknesses of Li et al.’s scheme and propose an improvement dynamic identity based multi-server authentication scheme. Analyses show that our proposed scheme can prevent several attacks and support the revocation of anonymity to handle the malicious behavior of a legal user with efficiency. The second study is to propose an advanced biometrics-based authentication scheme for a multi-server environment. Through a theoretical proof focused on security, functionality, and performance aspects, we show that our proposed scheme achieve higher security and efficiency as compared to previous schemes. In particular, our scheme overcomes the false positive problem in biometrics detection.
