Arvola, Mattias. « Good to use ! : Use quality of multi-user applications in the home ». Licentiate thesis, Linköping University, Linköping University, MDI - Interaction and Service Design Research Group, 2003. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-5686.
Texte intégralRésumé :
Traditional models of usability are not sufficient for software in the home, since they are built with office software in mind. Previous research suggest that social issues among other things, separate software in homes from software in offices. In order to explore that further, the use qualities to design for, in software for use in face-to-face meetings at home were contrasted to such systems at offices. They were studied using a pluralistic model of use quality with roots in socio-cultural theory, cognitive systems engineering, and architecture. The research approach was interpretative design cases. Observations, situated interviews, and workshops were conducted at a Swedish bank, and three interactive television appliances were designed and studied in simulated home environments. It is concluded that the use qualities to design for in infotainment services on interactive television are laidback interaction, togetherness among users, and entertainment. This is quite different from bank office software that usually is characterised by not only traditional usability criteria such as learnability, flexibility, effectiveness, efficiency, and satisfaction, but also professional face management and ante-use. Ante-use is the events and activities that precedes the actual use that will set the ground for whether the software will have quality in use or not. Furthermore, practices for how to work with use quality values, use quality objectives, and use quality criteria in the interaction design process are suggested. Finally, future research in design of software for several co-present users is proposed.

Wei, Nicklas, et Richard Blomberg. « Home sweet home : a case study on persuasive technology to promote usage of an m-health application by elderly living at home ». Thesis, Linnéuniversitetet, Institutionen för informatik (IK), 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-86874.
Texte intégralRésumé :
Much of the developed world is experiencing an aging population. This requires society to adapt to take care of a growing elderly population and improve their quality of life. Today, mobile systems are available that makes it possible to monitor and improve health (m-health). Even though these systems could be immensely helpful for the elderly population, this has not been the primary demographic for the current m-health systems. This case study aimed at examining how persuasive technology (technology for changing behavior and/or attitude) can be used to promote usage of m-health applications by the elderly. For this purpose, a theoretical framework for supporting m-health systems is proposed. This framework consist of persuasive technology (for motivation and support for fulfillment of human needs), knowledge of elderly issues in interacting with mobile interfaces, smartphone usability heuristics and the Plan-Do-Study-Act (PDSA) cycle (to support goalsetting and incremental progress). To determine how persuasive technology can be used to motivate elderly and find effective strategies for this purpose, the case study examined health behavior, motivations for healthy behavior, attitude to health, general goal setting behavior, needs, preferences, technological experience and self-efficacy, as well as usage of m-health systems using qualitative and participatory methods. Methods used included semi-structured interviews, future workshop, revolutionary rapid prototyping and usability evaluation. The findings of the interviews and the future workshop suggested the primary motivation for healthy behavior was derived from social aspects. Thus, the most effective persuasive strategies for the elderly likely target their need for social belonging and socialization. Based on the findings, an interactive prototype was developed. The prototype proposed an m-health application with self-monitoring that implemented an elderly community around healthy behavior, with opportunities to earn digital rewards and challenge other users to competition. The interactive prototype was then used in a usability evaluation to gauge its usability by the elderly and revised in higher fidelity according to their feedback.

Sensor-enabled computer systems capable of recognizing specific activities taking place in the home may enable a host of "context-aware" applications such as health monitoring, home automation, remote presence, and on-demand information and learning, among others. Current state-of-the-art systems can achieve close to 90% accuracy in certain situations, but the decision processes involved in this recognition are too complex for the end-users of the home to understand. Even at 90% accuracy, errors are inevitable and frequent, and when they do occur the end-users have no tools to understand the cause of errors or to correct them. Instead of such complex approaches, this work proposes and evaluates a simplified, user-centric activity recognition system that can be understood, modified, and improved by the occupants of a context-aware home. The system, named Distinguish, relies on high-level, common sense information to construct activity models used in recognition. These models are transferable between homes and can be modified on a mobile phone-sized screen. Observations are reported from a pilot evaluation of Distinguish on naturalistic data gathered continuously from an instrumented home over a period of a month. Without any knowledge of the target home or its occupant's behaviors and no training data other than common sense information contributed by web users, the system achieved a baseline activity recognition accuracy of 20% with 51 target activities. A user test with 10 participants demonstrated that end-users were able to not only understand the cause of the errors, but with a few minutes of effort were also able to improve the system's accuracy in recognizing a particular activity from 12.5% to 52.3%. Based on the user study, 5 design recommendations are presented.

Texte intégralRésumé :
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. Den föreslagna konstruktionen kommer att beaktas vid utformningen av Acreos hemautomatiseringssystem.

Haglund, Kristian, et 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.
Texte intégralRésumé :
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.

You, Wei. « Vision-based multiple user interaction with in-home large displays ». Thesis, University of British Columbia, 2008. http://hdl.handle.net/2429/5533.
Texte intégralRésumé :
In-home large displays such as TVs are becoming larger in size, and more
interactive in function. They start to be simultaneously used by multiple
people for various tasks in a dynamic setting. User interface issues such as
multiple users sharing the screen resources of the displays, and the usage
of multiple control devices have begun to emerge. We assume horizontally
laid out “personal interaction spaces” as the user interface for multiple users
to manage their screen real-estate. In this case, users often need to sign in
and out as well as have their personal spaces placed on the screen. Also,
the limited number and complex usage of conventional remote controllers
for TVs cannot satisfy the need of multiple interacting users.
In this thesis, we consider a
computer vision based system as a solution
to the emerging user interface issues. We built a vision system that tracks
the identities, positions and hand positions of people in front of a large
display to support our user studies of screen real-estate management and
multi-device management. We explore the usefulness of a vision system
through two user studies.
We designed the first study to compare the use of tracker-based mechanism versus manual ones for managing the display. Study Results suggest
that the tracking system is especially useful for simplifying the user sign
in/out process in conjunction with a manual method, and effective user-centric
placement of people’s interaction spaces.
As well, we designed a second study to explore whether contexts exist for
lower fidelity, gesture-based “remote controllers” for manipulating on-screen
objects. Study results show that gestural interfaces combined with high
fidelity devices such as a mobile phone in a group gaming scenario can be
useful for centralizing the control in the team and reducing errors. However,
gestural control is only suitable for simple, once-in-awhile interaction.

Texte intégralRésumé :
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.

In this work, a system for recognizing activities in the home setting that uses a set of small and simple state-change sensors, machine learning algorithms, and electronic experience sampling is introduced. The sensors are designed to be "tape on and forget" devices that can be quickly and ubiquitously installed in home environments. The proposed sensing system presents an alternative to sensors that are sometimes perceived as invasive, such as cameras and microphones. Since temporal information is an important component of activities, a new algorithm for recognizing activities that extends the naive Bayes classifier to incorporate low-order temporal relationships was created. Unlike prior work, the system was deployed in multiple residential environments with non-researcher occupants. Preliminary results show that it is possible to recognize activities of interest to medical professionals such as toileting, bathing, and grooming with detection accuracies ranging from 25% to 89% depending on the evaluation criteria used. Although these preliminary results were based on small datasets collected over a two-week period of time, techniques have been developed that could be applied in future studies and at special facilities to study human behavior such as the MIT Placelab. The system can be easily retrofitted in existing home environments with no major modifications or damage and can be used to enable IT and health researchers to study behavior in the home. Activity recognition is increasingly applied not only in home-based proactive and preventive healthcare applications, but also in learning environments, security systems, and a variety of human-computer interfaces.

Learning people's behavior in their homes is central to health sensing, behavioral research, and building smarter environments. In this thesis, we explore learning such information in a passive and contactless manner - without asking people to wear sensors on their bodies or change the way they normally live. We leverage that radio frequency (RF) signals bounce off people, and carry information about them. This thesis presents systems, algorithms, and machine learning models to analyze the signals in the environment and infer information about people's behavior and well-being. Specifically, we analyze the surrounding RF signals to infer people's movement patterns and enable continuous monitoring of gait velocity and stride length. We also sense people's sleep efficiency, sleep onset, and nocturnal awakenings using radio signals, without any wearable devices. Further, we demonstrate that radio signals carry information about people's identity and body shape. This thesis introduces the first system that reconstructs a person's silhouette using RF signals. We then develop this system further to identify users in their homes with no restrictions on their movement patterns. This thesis also shows that the combination of identity and movements allows us to analyze user behavior and interaction at home, without asking users to write diaries or deploy cameras in their living space. Finally, we introduce a new self-supervised learning method to infer appliance usage at home. Collectively, the models and systems in this thesis provide a toolkit for learning behavioral analytics at home from the surrounding radio signals, and addressing questions like who, what, and when, in a passive manner with minimal interference with users' lives.

The mobile world is rapidly changing: Smartphones have gone from portable messaging and email devices to streaming-video machines that surf the Web at blazing speed. Now-a-days a smartphone can provide computing capabilities, wireless communication capabilities, run software and perform other tasks just like any traditional computer. These amazing features of a smartphone and Open Source Android market helped in the development of this project. The purpose of this project is to develop an Android application for controlling various elements of user environment. User Controlled Environment is an Android application for home. The environment consists of smart lights, an Android mobile devices for playing music and a display. The application sends the user’s preferred settings to the environment and the respective settings are applied. The preferences are displayed on the screen. The user will be able to view and adjust a variety of environmental preferences. The preferences include the light’s color, light intensity, and the music. When the user exits the application the environment goes to a default state. The users can set preferences which include moods, seven colors of light, three levels of light intensity and songs that the users can select.

Texte intégralRésumé :
As a result of the diversity of home buyers within the current housing market, houses are increasingly designed with but little user input into the overall design process. Home builders require the development of design tools which will accommodate user needs within specific housing markets. This thesis investigates the reaction of builders to the participation of home buyers in the design process through the use of computer-aided design (CAD).A review of the role of computers within the homebuilding industry is provided, including an historical overview of the use of CAD. The state of the art in CAD software applications is explored, with an assessment made of three low-cost software programs. Following a description of the existing design process in the homebuilding industry, a proposed system of user participation is outlined. A survey is taken of six builders in the Montreal and Ottawa regions to determine industry response to home buyer use of CAD as a design tool.
An analysis of the survey results reveals that although the builders are not currently participants in such a process, they are tentatively positive in their receptiveness to the idea of user-related CAD. The builders express many reservations concerning the available CAD systems, and they declare little interest in adopting the process as it presently exists. The relevant computer programs are found wanting, revealing a need for further development of both the software applications and the procedure for implementing CAD at the user participation level. Suggestions are offered for improvements in the process to the benefit of builder, designer, and end user.

Texte intégralRésumé :
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.

Texte intégralRésumé :
As technology becomes ever more pervasive, the challenges of home automation are increasingly apparent. Seamless home control, home monitoring and home programming by the end user have yet to enter the mainstream. This could be attributed to the challenge of developing a fully autonomous and extensible home system that can support devices and technologies of differing protocols and functionalities. In order to offer programming facilities to the user, the underlying rule system must be fully independent, allowing support for current and future devices. Additional challenges arise from the need to detect and handle conflicts that may arise among user rules and yield undesirable results. Non-technical individuals typically struggle when faced with a programming task. It is therefore vital to encourage and ease the process of programming the home. This thesis presents Homer, a home system that has been developed to support three key features of a home system: control, monitoring and programming. Homer supports any third-party hardware or software service that can expose its functionality through Java and conform to the Homer interface. Stand-alone end user interfaces can be written by developers to offer any of Homer's functionality. Where policies (i.e. rules) for the home are concerned, Homer offers a fully independent policy system. The thesis presents a custom policy language, Homeric, that has been designed specifically for writing home rules. The Homer policy system detects overlaps and conflicts among rules using constraint satisfaction and the effect on environment variables. The thesis also introduces the notion of perspectives to ease user interactivity. These have been integrated into Homer to accommodate the range of ways in which a user may think about different aspects and features of their home. These perspectives include location, device type, time and people-oriented points of view. Design guidelines are also discussed to aid end user programming of the home. The work presented in this thesis demonstrates a system that supports control, monitoring and programming of the home. Developers can quickly and easily add functionality to the home through components. Conflicts can be detected amongst rules within the home. Finally, design guidelines and a prototype interface have been developed to allow both technically minded and non-technical people to program their home.

Grant, Tom. « The involvement of users in the design of home use medical devices : challenges and incentives for change ». Thesis, Loughborough University, 2014. https://dspace.lboro.ac.uk/2134/16283.
Texte intégralRésumé :
The prevalence and use of medical devices in the home environment continues to grow in the United Kingdom (UK) and Worldwide. It is recognised that such devices offer significant benefits to both patients and the National Health Service in the UK. The design of home use medical devices however represents a considerable challenge to designers and manufacturers alike. Developing devices that are usable and understandable by inexperienced, lay or dexterity impaired users requires an understanding across a breadth of disciplines. Previous research in this field has explored these challenges in attempt to offer support for developers of home use medical devices. There have been very few studies however that have explored whether the design community actually need, want or use such guidance, before considering whether this literature is adopted correctly. Through case studies, an online survey and in depth interviews this thesis suggests that industry practitioners are sceptical of the value of design guidance towards user involvement in home use medical device design. Consequently the practitioners in this research make little or no use of the formal design methods and supportive guidance documents available to them. More typically, practitioners in the home use medical device field use their own personal experiences and knowledge from working in the industry to adapt their own approaches to design. This thesis reports that the greatest challenge to involving users in the design of home use medical devices are the internal corporate and traditionally hierarchical barriers between stakeholders within the design process. In contrast to previous research offering support for designers and developers of home use medical devices this thesis calls for a wider change in design practice to facilitate the application of usability principles. As a conclusion to this thesis, recommendations for further research to address these changes in practice are proposed to industry professionals in the medical device industry. This thesis is submitted as part of the requirement for the Degree of Doctor of Philosophy at Loughborough University.

Most household consumers in the US are unaware of their electrical usage or the price of electricity until they receive their monthly bill. However, they are concerned about being "wasteful" when it comes to electricity use. But most consumers have no idea what being wasteful means. What if there was a way to show residential consumers their real-time electrical usage in terms of price or in terms of environmental emissions from non-renewable power plants? Would this appeal to their concerns about wastefulness and cause them to change their behavior with household appliance use? To test this question an experiment was designed, and multiple prototypes were built. The experiment consisted of a prototype showing a traffic light color pattern of two lights. The first light indicated the price/emissions metric chosen based on user allegiance. The second light indicated the usage of electricity in their home.
After running this experiment, the key takeaway was that that consumers will change their electrical usage behavior based on a metric that matters to them but will not compromise comfort or convenience over price or emissions. Electric energy trading in the US is a complicated system and fundamentally a business. Electrical energy is predicted and traded the day before, generally using clean energy sources in the US. However, if there is a surge in demand on the predicted day, dirty power is turned on. A dirty power plant is classified as being harmful to the environment by burning coal or oil. Dirty power plants are also expensive to the consumer and inefficient in the electric grid but can be turned on instantly in times of need. Because of this, the trading system is designed to minimize the use of dirty power. The electricity trading models follow a principle called the "duck curve".
The duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and renewable energy production. Generally, grid usage follows the duck curve.

Genre conventions emerge across discourse communities over time to support the communication of ideas and information in socially and cognitively compatible forms. Digital genres frequently borrow heavily from the paper world even though the media are very different. This research sought to identify the existence and form of a truly digital genre. Preliminary results from a survey of user perceptions of the form and content of web home pages reveal a significant correlation between commonly found elements on such home pages and user preferences and expectations of type. Results suggest that the personal home page has rapidly evolved into a recognizable form with stable, user-preferred elements and thus can be considered the first truly digital genre.

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.

Weng, Hsueh-Pei. « A sensitising tool for smart home designers : based on user-oriented product design research into the home life of older adults in the UK ». Thesis, Brunel University, 2010. http://bura.brunel.ac.uk/handle/2438/4310.
Texte intégralRésumé :
Focusing on the needs of users, design can leverage new product development process by offering insightful knowledge of those needs. This research investigates the technology development of smart homes. Design is utilised as a product research tool to identify key insights of the home life of the older adults living in the UK, and for the purpose of informing the front-end of the new product development process. The review of the literature in the field of smart homes suggests that the developments have lagged by a technology-push approach, the lack of appropriate concepts from users’ perspectives as well as the lack of development strategy, which has consequently been reflected in consumers’ reluctance towards smart homes. As a result, this doctoral research aimed to ‘develop a user-oriented product design research tool that improves the understanding of the home life of older adults.’ To achieve the aim, this research employs qualitative methodology to develop a research process that utilises the cultural probe, semi-structured interview and video tour. Informed by ethnographic tradition, this research establishes its trustworthiness and credibility by employing a thorough process of analysis (qualitative analysis with computer-assisted software NVivo 8 and peers debriefing) and evaluation (creative workshop and evaluative interview) with practitioners from the field of product design, design management and design education. The result of the field investigation is presented as ten personas and taxonomy of nodes, which form the contribution of this research, a sensitising tool and process. This research contributes a sensitising tool - a design-led, user-inspired and participatory product design research that the offers insightful knowledge of those older adults and their relationships with their homes living in the UK. This sensitising tool is developed for the smart home designers for the purpose of generating new product ideas and challenges designers’ preconception of users and smart homes, and provokes reflections on the practices of user-centred and user-participatory design, as examined in the creative workshop. In addition, this research also contributes to the growing debate surrounding the issues relating to ethnographic user research and the use of cultural probe for the design of new smart homes.

Texte intégralRésumé :
Today we live in an information society that is constantly growing in terms of the amount of information that are processed, stored, and communicated. Information security is a field that is of concern for both the individual and the society as a whole, as both groups are exposed to information every day. A society like this will demand more emphasis on information security. Previous researchers that has addressed this problem argues that security awareness is the most significant factor in order to raise the general security level. They also mention education as a solution to increase the security awareness and thereby achieve a secure environment. The aim of this thesis is to examine the differences between trained and untrained home users in security awareness and behaviour. The research was conducted, using a quantitative method in form of a survey research with the distribution of self-completion questionnaires. The study has a total of 162 respondents that participated. The result was presented and analysed through the use of the software program, IBM SPSS. The results of the findings suggest that the awareness of the trained home users is higher than of those who are untrained home users. Additionally, the discussion suggests that the home users who have participated in awareness raising initiatives, such as education and training, does not necessarily apply more security measures in their home environment, than those who are regarded as untrained home users. Hence, this study suggests that the increase in awareness may not necessarily be the only factor that affects the user’s behaviour, since those who have not participated in awareness raising initiatives applies security measures, almost to the same extent to those who have. This thesis might be able to act as a foundation for future research within the field, considering that the research is a comparative study between trained and untrained home users of the variables security awareness and behaviour where the found results, does not fully agree with previous research. However, an increase in awareness is a good start, but may need to be paired with appropriate training from other parties, such as internet service providers (ISPs) and banks. Maybe the solution could be to develop and strive for a continuous information security culture of the Swedish society, which may result in a deeper learning and understanding of security issues and inspire home users to be engaged and proactive about their information security behaviour.

Texte intégralRésumé :
The preferred clothing styles, and consideration factors of selected female underarm crutch users were investigated along with the comparison of body measurements between permanent and temporary crutch users. Results indicated permanent crutch users with strong function orientation preferred set-in sleeves, buttoned cuffs, enlarged jewel neckline, shawl collar and bloused silhouette. This was different from the temporary crutch users preference. The measurement difference of the same weight category showed that the proportion of permanent crutch users, with larger upper torso, was different to that of temporary crutch users. Factors for permanent crutch users selection of clothing included function, fit and fabric when evaluating illustrations, and comfort and esthetics were additional factors after trying on the prototypes of their choice. The prototype designs ameliorated the aspect of five subjects.

Burris, Andrea. « Creature comforts : an exploration of comfort in the home ». Thesis, Loughborough University, 2014. https://dspace.lboro.ac.uk/2134/16314.
Texte intégralRésumé :
In response to climate change, there is a growing need for the UK to reduce carbon emissions in the domestic sector. As a majority of energy consumed within the domestic sector is as a result of space and water heating, research in the field focuses on thermal comfort. The literature on thermal comfort is dominated by an examination of the physiological aspects, and although the influences of psychological and socio-cultural aspects are often recognised, their relationship to the physiological aspects is not fully understood. Additionally, the literature typically studies various elements of comfort (e.g. thermal, acoustic, lighting, etc.) in isolation to each other rather than taking a holistic approach which would mirror how they are experienced in the real world and identify potential associations. As a result, this thesis explores the multi-dimensions of comfort in the domestic environment. This research begins by taking a user-centred approach to exploring UK householders perspectives of comfort in the home. Through interviewing householders, the findings revealed householders attributed a wide scope of factors to their own experience of comfort, from aesthetics to feeling secure in their home; the findings highlighted the significance of psychological factors to householders comfort. The following stage involved a focused and in-depth exploration of the psychological dimensions of domestic comfort through photo elicitation interviews. The findings supported the presence of four intertwined psychological dimensions and further established the multidimensional nature of comfort. The final study was conducted to establish when comfort and unwinding takes place in householders everyday lives. Through the use of two self-reporting ethnographic tools, namely SenseCams and diaries, householders were observed in their homes. The findings captured householders engaging in various comfort making activities and also demonstrated the value of using self-reporting tools in the home context. In the final stage, a classification of domestic comfort was generated which presents an accumulation of the findings from this research to produce a holistic and multi-dimensional notion of domestic comfort.

Texte intégralRésumé :
In order to find good solutions to face the aging problems, a European Union project-MonAMI was established with the main purpose of enhancing old people’s life by using mainstream technological platforms to deliver helpful services. This thesis project is a sub-project of MonAMI project which focus on design and develop a graphical user interface for a touch-screen monitor that is used to deliver several useful services to old people who live in their home environment. Universal design principles, evaluation results from older prototypes, characteristics are the fundamental design guidelines for the interface design. The development processes have followed both User-Centered Design process and a modified version of task-artifact development life cycle. The biggest challenge for this thesis was to identify the most perceivable and acceptable design solution for the old user. This means the solution has to be good in both visual and logical way. Therefore, the solution is produced with an incremental progressive procedure. In this procedure, expert evaluation was used as the main method to filter out less perceivable ideas. A user test involved with two actual users was carried approaching to the end of the project and identified many critical issues in the solution. The final solution was presented with a low-fidelity prototype by using Microsoft PowerPoint Presentation to give the future product an insight view on the interface design for elder users.

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.

Texte intégralRésumé :
This research explores technological interventions to reduce energy use in the domestic sector, a notable contributor to the global energy footprint. In the UK elevated challenges associated with renovating an outdated, poorly performing housing stock render a search for alternatives to provide immediate energy saving at low cost. To solve this problem, this thesis takes a holistic design approach to designing and implementing a spatiotemporal heating solution, and aims to investigate experiences of comfort, thermal comfort concepts for automated home heating, users’ interactions and experiences of living with such a system in context, and the underlying utility of quasi-autonomous spatiotemporal home heating. The mixed-methods research process was employed to explore and answer four questions: 1) what is the context within which these home heating interfaces are used, 2) to what extent can spatiotemporal automated heating minimise energy use while providing thermal comfort, 3) how are different heating strategies experienced by users, and 4) How do visibility of feedback, and intelligibility affect the user experience related to understanding and control? Ideation techniques were used to explore the context within which the designs are used with regard to all factors and actors in play and resulted in a conceptual model of the context to be used as a UX design brief. This developed model used mismatches between users’ expectations and reality to indicate potential thermal comfort behaviour actions and mapped the factors within the home context that affected these mismatches. Potential user inclusion through participatory design provided stakeholder insight and interface designs concepts to be developed into prototypes. The results of a prototype probe study using these prototypes showed that intelligibility should not be an interface design goal in itself, but rather fit in with broader UX design agenda regarding data levels, context specificity, and timescales. Increased autonomy in the system was shown not to directly diminish the experience of control, but rather, control or the lack of originated from an alignment of expectations and reality. A quasi-autonomous spatiotemporal heating system design (including a novel heating control algorithm) was coupled with the design of a smartphone interface and the resultant system was deployed in a low-technology solution demonstrating the potential for academic studies to explore such automated systems in-situ in the intended environment over a long period of time. Assessment of the novel control algorithm in an emulated environment demonstrated its fitness for purpose in reducing the amount of energy required to provide adequate levels of thermal comfort (by a factor of seven compared with EnergyStar recommended settings for programmable thermostats), and that these savings can be increased by including occupants’ thermal preference as a variable in the control algorithm. Field deployment of that algorithm in a low-tech sensor-based heating system assessed the user experience of the automated heating system and its mobile application-based control interface, as well as demonstrated the user thermal comfort experience of two different heating strategies. The results highlighted the potential to utilise the lower energy-use “minimise discomfort” strategy without compromising user thermal comfort in comparison to a “maximise comfort” strategy. Diverse heating system use behaviours were also identified and conceptualised alongside users’ experiences in line with the developed conceptual model. A rich picture analysis of all previous findings was utilised to provide a model of the design space for home automated heating systems, and was used to draw interface design guidelines for a broader range of home automation control interfaces. The work presented here served as important first steps in demonstrating the importance of assessing UX of automated home heating systems in situ over elongated periods of time. Novel contributions of (i) conceptual model of automated systems’ domestic context and thermal comfort behaviours within, (ii) nudging this behaviour by selecting a “minimise discomfort” heating strategy over “maximise comfort”, (iii) using UX to influence user expectations and subsequently energy behaviour, and (iv) inclusion of thermal preference in domestic heating control algorithm were all resultant of examining naturally occurring behaviours in their natural setting. As such, they are important exploratory discoveries and require replication, but provide new research directions that would allow reduction of domestic energy use without compromise.

Texte intégralRésumé :
The researchers predict a future, where people’s interaction with things is decreased and things become more autonomous, requiring less control from people, aiming to make life easier. However, the question is if we really are ready to let go of the control over such systems in order to have easier life. This is what this research through design project is aiming to find out through a research question How the different user interaction modalities with IoT devices at home influence the sense of control for users? and sub-question How the sense of control over IoT devices would influence how people trust them? With the help of prototype, questionnaire and online sessions, two lists of guidelines were created, consisting of points to consider while designing for such systems from control and trust perspective.The angle was narrowed down to a morning routine and interaction with the alarm clock connected to a coffeemaker.

Texte intégralRésumé :
Smart lighting has in more recent times developed into a broader market, where it has moved into people’s homes, as opposed to in the beginning when it was used more at office environments due to its benefits of high potential energy savings (Santamouris & Dascalaki, 2002). Today Smart LightingSystem (SLS) provides the opportunity for private home lighting fixtures and sensors to be connected wirelessly and connect with other internet of things (IoT) products to perform required tasks. Thus, the purpose of this study is to investigate if how Swedish residents use SLS at home. To answer this, we first needed to do an inventory of the homes currently using Smart lighting and if why it is being used. As a method for data collection of the study, a web-based survey including a mixed-question questionnaire was used with Single choice, Multiple-choice questions and a 7-Point Likert Scale. It consisted of 20 questions and got 114 respondents to answer about their usage of SLS. Out of these114, 39 participants were users of SLS. The raw data generated by the survey were analysed and visualized using descriptive statistics with tools like Pivotable and Pivot charts in Microsoft Excel. In general, Functionality is the most important aspect when investing in SLS across all age-groups and gender. Turn On/ Off and Dimming is the most common way of controlling the lights and the Smartphone for interaction in the home environment.

Park, Hyo Ri. « Whole Care+ : An integrated health care for the elderly living in their homes ». Research Showcase @ CMU, 2011. http://repository.cmu.edu/theses/22.
Texte intégralRésumé :
The elderly experience their health getting significantly deteriorated as they age. They suffer not only from chronic diseases but from various geriatric diseases such as high blood pressure, arthritis and cardiovascular disease. Their mental health also retreats creating challenges for the elderly from the loss of short term memory to dementia. Furthermore, after they retire, the elderly’s social network decreases as their social activities are inevitably limited to a small group of people like families and friends.
With the face of such impairments in their physical, mental and social health, many elderly cannot help but are being institutionalized or sent to specialized places like nursing homes, which provide them professional care. However, a study indicates that most Americans prefer to stay in their homes as they get older since they can maintain their social connections to neighbors and friends, be close to their medical caregivers in town as well as attain emotional comfort and security with familiar surrounding and environments. On top of that, Americans of all ages value on keeping their ability of independence and autonomy by controlling their lives in general.
Various health care-aid devices and services appear to offer specific support to health care activities for the elderly in their homes. However, such aids have more focused only on when the elderly’s health is degraded or on very specific areas such as tracking health data like blood pressure, blood sugar and calorie intakes.
The elderly need comprehensive understanding about their health problems, healthy daily habits and timely interactions with their families and caregivers, in order to keep independent living safely in their places. Smart Home technology has much potential to support the elderly’s independent living as well as interactions with others. To better understand this, we conducted a user-centered design project which looks at the management of the elderly’s health enabled by Smart Home technology.

Texte intégralRésumé :
Do residents find value in smart home functions? How should these functions be designed to offer user benefit? These were the governing questions of this study that involved nearly 200 families in three different housing projects during five years of occupancy. The housing units were equipped with advanced smart homes solutions, electronic and digital devices to control them, and a set of functions to increase comfort, safety and security in the homes. The evaluations of the residents' use and benefits were accomplished in two different phases, i) evaluation of the user expectations' before and direct after occupancy and ii) long-term experiences after 3-5 years. A third phase of the study represents a radical shift in view. Issues related to innovation and organisation of service delivery were brought into the fore. The research is founded on the multiple case-based methodology. Literature studies were effected. Data acquisition was based on interviews and questionnaires. Theoretical models from different research areas were used in order to analyse observations and to arrive to grounded conclusions. Important conclusions include the fact that smart home functionalities must be developed as close as possible out of the users' genuine needs as experienced in their daily lives. Failure to attain accessibility to a certain function will cause disappointment and will be forsaken. To gain and over time preserve the user's trust in smart home functions or in a system as a whole is conclusive for the their use. Another conclusion is that a viable business model for smart homes must include the occupancy phase. Surveillance and maintenance of smart home systems must be secured over time. It is argued that the failure of establishing a viable long-term service to homes to the benefit to the user depends highly on the market’s ability to supply the homes with appropriate services over time. Possible ways to mediate revealed shortcomings are outlined and what role and responsibility the housing construction industry has to consider with the further development of smart homes.QC 20100809

Texte intégralRésumé :
The primary purpose of this research was to examine the adoption of computer security software in the home computer environment. The use of the Health Belief Model as a framework to design a model to examine home user adoption of computer security provided the basis for this research.
The method of the investigation was a cross-sectional study using a self-reported web-based survey to test the theoretical model derived from the Health Belief Model. The survey targeted individuals who are responsible for the selection, installation, and maintenance of software on their home computers. The data collection relied on a snowball sampling technique that recruited a total of 186 participants who completed the online survey.
The research model contains a total of 26 hypothesized relationships that were tested using multiple regression analysis techniques. The research model contains six main predicting variables (perceived vulnerability, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action) and four moderating variables (age, gender, education, and prior experience of attack). The model explains 30.4% of the variance in computer security usage, the dependent variable in the research model.
The results demonstrate that certain constructs found in the Health Belief Model are more effective than others in motivating individuals to utilize computer security software. Specifically, the results show that perceived vulnerability (H1), perceived barriers (H4), self-efficacy (H5), and the two-way interactions of age and barriers (H8d), education and benefits (H9c), prior experience and perceived severity (H10b), and prior experience and self-efficacy (H10e) had significant effects on computer security usage. Additionally, prior experience was found to have a significant main effect on the dependent variable.
Information from this research provides evidence that the Health Belief Model can be used to study the computer security usage behavior of home computer users. Further, the relationship of perceived vulnerability and computer security usage provides a way for practitioners to increase computer security usage behavior through targeted media campaigns.

Texte intégralRésumé :
Current dialogue systems can handle friendly and collaborative communication that supports diverse types
of interactions, such as menus in which the user is asked to choose an option, form filling in which the user
is asked for specific information, commands for expressing users' orders, and complex questions that can
even reference previously evoked entities. Consequently, dialogue systems seem to be useful for
accessing different types of applications. In particular, spoken dialogue systems are appropriate for
devices that do not allow web browsing, such as telephones, or the use of hands, such as vehicle GPS.
Practical dialogue systems are mostly adapted to the functionality of the specific application they access,
specially those incorporating speech, since voice technology still presents recognition problems in open
domains. Because the adaptation of those DS to new applications is expensive and has to be done by
experts, many studies have focused on the problem of developing dialogue systems that can be used for
different applications and languages. Most relevant of those systems use domain and dialogue models,
and have reusable domain-independent components. However the cost of adapting those systems to other
types of applications is still high, specially in mixed-initiative systems, in which the dialogue initiative can be
taken either by the user or the system.
The work in this thesis is particularly concerned with dialogue systems for guiding the user to access web
services. The huge amount of web information increase the need of communication systems adaptable to
different types of users, languages, services and channels. For this reason, dialogue systems can improve
the usability and accessibility of web contents.
We have developed a multilingual mixed-initiative dialogue system for guiding the user when accessing
web contents. To facilitate the adaptation of the dialogue system to new services and languages, the main
functions of the system (language processing, dialogue control and task management) is performed by
independent modules). The dialogue system developed consist of four independent general modules
(Language Understanding, Language Generator, Dialogue Manager and Task Manager) as well as two
knowledge structure accessible by all these modules (dialogue context and domain description).
Application and language-dependent resources are incorporated in separated data structures. In order to
minimize the need for application and language-restricted data we propose the use of separated general
bases for representing linguistic, application and domain knowledge.
In order to achieve a friendly communication, the dialogue management module follows a formal dialogue
model, based on the information state model, that uses of a rich representation of the dialogue context.
The dialogue manager modules also incorporates an independent submodule to adapt the dialogue
strategies, according to how well the communication is progressing. This component uses a conversation
model (obtained from a previously analysed corpus of dialogues) to determine the degree of the system
initiative in the next intervention considering several features on how well the conversation is doing.Els sistemes de diàleg permeten establir una conversa agradable i participativa, en la que es poden donar diferents tipus d'iteracions, com ara menús amb els que es presenta a l'usuari un conjunt d'opcions per a que n'esculli una, comandaments per expressar ordres, preguntes molt concretes i també preguntes complexes que poden fer referència a entitats prèviament evocades. Precisament perquè els sistemes de diàleg permeten diversos tipus d'iteracions, són adequats per facilitar l'accés de l'usuari a aplicacions diferents. A més, els sistemes de diàleg accessibles mitjançant la veu són molt apropiats per accessoris ens els que no es poden utilitzar les mans, com ara el telèfon o els aparells de GPS instal·lats als vehicles. La majoria de sistemes de diàleg que s'han desenvolupat s'han adaptat a una aplicació concreta, ja que el seu funcionament millora molt quan la cobertura del llenguatge es limita al necessari per expressar un conjunt de tasques determinades. El problema dels sistemes de diàleg desenvolupats per una aplicació concreta és que no són fàcilment adaptables a d'altres, el treball a realitzar és costòs i l'han de realitzar experts. Per a superar aquesta limitació s'han realitzats molts treballs de recerca centrats en el desenvolupament de sistemes de diàleg fàcilment adaptables a diverses aplicacions i llengües. Els treballs més rellevants en aquesta línia proposen l'ús de models de diàleg i del domini i la organització del sistema de diàleg en mòduls generals independents, reutilitzables per diferents aplicacions. Tot i que aquestes propostes redueixen el cost l'adaptació dels sistemes de diàleg a noves aplicacions, no s'elimina, menys quan es tracta de sistemes on la iniciativa de la comunicació és mixta, pot ser tant del sistema com de l'usuari. El treball d'aquesta tesi està centrat en els sistemes de diàleg per guiar als usuaris quan accedeixen a la serveis i continguts disponibles a la web. Hem desenvolupat un sistema de diàleg multilingüe d'iniciativa mixta per guiar a l'usuari quan accedeix als continguts de la web. Per facilitar la adaptació del sistema a nou serveis i noves llengües, les diferents tasques del sistema (processament del llenguatge, gestió del diàleg i accés a l'aplicació) són realitzades per mòduls independents. El sistema de diàleg desenvolupat consisteix en quatre mòduls independents que controlen les quatre tasques principals ( comprensió de la intervenció de l'usuari, generació de resposta, gestió del diàleg i gestió de tasques de l'aplicació) i dues estructures de dades accessibles per aquests mòduls (context del diàleg i descripció del domini). Els quatre mòduls generals del sistema utilitzen estructures dades dependents de l'aplicació (servei) i de la llengua. Amb la finalitat de facilitar la incorporació d'aquestes estructures de dades necessàries per cada nova aplicació proposem la utilització d'estructures de dades generals per representar el coneixement conceptual de l'aplicació i el seu domini, així com el coneixement lingüístic. Per tal de poder assolir una conversa agradable el gestor de diàleg incorpora un model de diàleg formal, basat en el model de l'estat de la informació, que es caracteritza per utilitzar una representació rica del context. El gestor de diàleg també incorpora un submòdul independent per adaptar les estratègies de diàleg considerant els possibles problemes que apareixen a la conversa. Aquest component utilitza un model de conversa ( desenvolupat a partir de l'anàlisi d'un corpus de diàlegs obtinguts en interaccions prèvies amb el sistema) per determinar el nivell d'iniciativa que ha de mostrar el sistema per respondre. En aquest model es consideren diferents dades relacionades amb la comunicació (per exemple, si s'ha entès perfectament la última intervenció de l'usuari, si ha demanat ajuda,...).

Texte intégralRésumé :
Au cours des dernières années, la révolution numérique a continué sa progression. Les technologies de l'information et des communications (TIC) ont totalement changé la vie quotidienne des gens à leur domicile (concept de « maison numérique »). Pendant ce temps, non seulement le volume des émissions de CO2 produit par les TIC, ce qu'on appelle l'empreinte carbone, est sans cesse en croissance mais elle s'accompagne également d'une hausse du prix de l'électricité, augmentant fortement la part des équipements numériques dans la budget global des ménages. Ainsi, pour des raisons environnementale et économique, réduire la consommation d'énergie dans les nombreux équipements du réseau domestique est devenu un enjeu majeur. Dans ce contexte, la thèse porte sur la conception, l'évaluation et la mise en œuvre d'un ensemble de mécanismes dans le but de répondre aux problèmes de consommation d'énergie sur les réseaux locaux rassemblant les équipements numériques domestiques. Nous proposons un réseau de contrôle qui est formé par des noeuds de contrôle de l'énergie placés au-dessus du réseau traditionnel. Chaque nœud de contrôle est relié à un dispositif en vue de coordonner les états d'alimentation de l'équipement domestique associé.. Un démonstrateur pour un système Home Power Efficiency (HOPE) a également été mis en œuvre. Il démontre la faisabilité de la solution technique que nous proposons pour le contrôle de l'énergie dans un réseau domestique réel avec des scénarios réels qui sont souvent utilisées par utilisateur. Après avoir analysé le mode d'utilisation des équipements du réseau domestique, nous proposons un système de gestion d'énergie qui contrôle ces équipements minimisant ainsi que leur consommation. Le système est basé sur l'analyse des services collaboratifs, chaque service est découpé en blocs fonctionnels atomiques, distribués dans les différents équipements. Cela permet de gérer avec plus de précision les besoins énergétiques de chaque équipement de manière à n'alimenter que les composants nécessaires au service demandé. Pour conclure ces travaux, nous avons également cherché à minimiser les impacts de l'économie d'énergie sur la qualité d'expérience perçue par l'utilisateur (notamment le délai d'activation des services). Nous proposons un système de gestion d'énergie pour des services collaboratifs offrant plusieurs compromis possibles entre la consommation d'énergie et le délai d'activation des services dans un réseau domestique. Il est complété par un algorithme d'apprentissage du comportement des utilisateurs domestiquesIn recent years, Information and Communications Technology (ICT) has totally changed the people daily life in the Digital Home. Meanwhile, not only the amount of CO2 emission of ICT, so called ''footprint'', is increasing without cease, but also the price of electricity is constantly rising. Thus, it is quite important to reduce energy consumption in the home network and home devices for the environmental and economic reasons. In order to cope with this context, the thesis concerns the design, the evaluation, and the implementation of a novel set of mechanisms with the purpose of responding to home network energy consumption problems. We proposed firstly an Overlay Energy Control Network which is formed by the overlay energy control nodes. Each node is connected to one device which forms an overlay control network to coordinate the power states of the device. Then, a testbed for HOme Power Efficiency system (HOPE) is implemented to demonstrate the technical solution for energy control in a real home network environment with several frequently used scenarios. After analyzing user's way of use of their home network equipment, we propose a power management which controls the devices based on the analysis of the collaborative services. These frequently used collaborative services require different functional blocks in different devices. This model provides the possibility to turn on the right requested functional blocks in the right device at the right moment. Finally, based on the former contribution, the collaborative overlay power management offers several possible tradeoffs between the power consumption and the waiting delay in the home network

The present study's purpose was to investigate the home care staff's experiences of working as key workers, which factors they consider is relevant to key working and what obstacles and opportunities they experience in their work as a key worker. The study also focused on how the home care staff perceive that key working can enable user influence. A qualitative approach was used and the material for the study was collected through semi-structured interviews. The result shows that there are areas for improvement that may develop key working. The study shows that the staff generally feel that working as a key worker works well and that it can enable user influence in many areas. The study finally illustrates factors such as continuity, working relationship oriented, and taking responsibility, as significant for key working to work as successfully as possible.Föreliggande studies syfte var att undersöka hemtjänstpersonalens upplevelser av att arbeta med kontaktmannaskap, vilka faktorer de anser är av betydelse för ett fungerade kontaktmannaskap samt vilka hinder och möjligheter de upplever i sitt arbete med kontaktmannaskap. Därtill fokuserade studien på hur hemtjänstpersonalen upplever att ett kontaktmannaskap kan möjliggöra brukarinflytande. En kvalitativ ansats användes och materialet till studien samlades in genom semistrukturerade intervjuer. Resultatet visar att det finns hinder som kan påverka personalen att uppnå det som är syftet med kontaktmannaskapet samt att det finns förbättringsområden som kan utveckla kontaktmannaskapet. Studien visar att personalen överlag upplever att arbetet med kontaktmannaskapet fungerar bra samt att de upplever att ett kontaktmannaskap kan möjliggöra brukarinflytande inom många områden. Studien åskådliggör slutligen faktorer såsom kontinuitet, att arbeta relationsorienterat samt att man tar sitt ansvar som kontaktman som betydande, för att ett kontaktmannaskap ska fungera så framgångsrikt som möjligt.

Texte intégralRésumé :
Hydroponics is a method of cultivating plants without the use of soil. Soil acts as a growth medium which gives plants stability, provides nutrients and allows roots to be kept wet without drowning. In hydroponics the soil’s functions are replaced by synthesized methods. Stability comes from a substrate (i.e. LECA, rockwool perlite).The 16 essential nutrients are solved in water which are distributed to plants’ roots by different techniques. To generate photosynthesis natural light is replaced by artificial light, especially red light in the proximity of 660 nm. Hydroponics has been used as a cultivation method for at least 2000 years. During the 20th century industrial applications became common since plastics allowed for complex systems engineering. The method also makes it possible to grow the same amount of crops with approximately 10% water usage and 25% of the area compared to conventional cultivation. During the past few years systems for home use has emerged but the product genre is still in its cradle. This master thesis covers a new conceptual design of a hydroponic home system. The project was carried out at Omecon AB in Stockholm as a consulting design project. Omecon AB is an engineering consultant agency within mostly mechanical construction looking to widen the competence base. Using a design process based on Human-Centered Design the project involved the stakeholders users, extreme users, Omecon AB, plant experts, electronics engineering and service as well as plastics design engineering. Additional/supplemental economical–, ecological– and social sustainability aspects has been considered during all phases of the process. By using the Human-Centered Design process the problem range is expanded from its initial state which results in a more complete end result. Common methodology altered with some unorthodox twists has been utilized throughout the project. The final result is a conceptual hydroponic system for home environment which is designed as an interior design product as well as a high-performance cultivation system. By using natural materials such as wood and steel the users expands its life span and thus mitigates the negative environmental impact. Another aspect which prolongs the products life span is the modular usage which lets users vary and choose their preferred settings. All manufactured materials included in the final concept were flow resources and the parts were engineered to be easily separable for future replacement and recycling. A new type of pot was invented along with a new way of adjusting the height-wise position of lamps. The aeroponic technique, which was applied to this concept, is generally considered to generate the largest plants and thus comprises higher performance compared to other home systems. The use of substrate was also eliminated which decreases continous material consumption within hydroponics.Hydroponik är en metod för att odla växter utan jord. Jord i odling agerar som ett växtmedium som ger plantor stabilitet, tillför näringsämnen och tillåter rötter att vara i väta utan att dränka dem. I hydroponik ersätts jordens funktioner med syntetiska metoder. Stabilitet ges av ett substrat (t.ex. LECA-kulor, stenull eller perlit). De 16 essentiella näringsämnena löses i vatten och distribueras till plantors rötter med hjälp av olika tekniker. For att skapa fotosyntes ersätts naturligt ljus med artificiellt ljus. Speciellt rött ljus i närheten av 660 nm. Hydroponik har använts som odlingsmetod i åtminstånde 2000 år. Under 1900-talet blev industiella applikationer vanliga eftersom plast möjliggjorde tillverkling av komplexa system. Metoden tillåter även att odla samma mängd grödor med 10% av vattenmängden och 25% av ytan jämfört med konventionell odling. Under de senaste åren har system avsedda för användning hemma blivit vanligare men produktgenren är fortfarande ung. Det här examensarbetet täcker en ny konceptuell design av ett hydroponiskt system för hemmabruk. Projektet utfördes på Omecon AB i Stockholm som ett konsultarbete inom design. Omecon AB är en konsultfirma som mestadels är verksamma inom mekanikkonstruktion men de vill vidga sin kompetens. Genom användning av en designprocess som har baserats på Human-Centered Design har projektet involverat intressenterna användare, extrema användare, Omecon AB, växtexperter, en elektronikingenjör samt plastkonstruktion. Vidare har aspekter inom ekonomisk–, ekologisk– och social hållbarhet beaktats genom alla faser av processen. Via användning av Human-Centered Design-processen har problemrummet expanderats från den initiala utgångspunkten vilket resulterar i ett mer komplett slutresultat. Vanlig metodik varvat med okonventionella anpassningar har använts genom projektet. Slutresultatet består av ett konceptuellt hydroponiskt system för hemmabruk som är designat som en inredningsprodukt samt ett odlingssystem med hög prestanda. Genom användning av naturliga material som trä och stål förlänger användarna produktens livslängd och på så sätt förmildras den negativa klimatpåverkan. En annan aspekt som förlänger produktens livslängd är moduläriteten som låter användare variera och välja deras föredragna inställningar. Alla tillverkade material inkluderade i slutkonceptet var flödesresurser och delarna konstruerades så att de går lätt att separera för framtida ersättning och återvinning. En ny typ av kruka uppfanns tillsammans med ett nytt sätt att justera höjden av lamporna. Den aeroponiska tekniken, som används is konceptet, är allmänt ansedd att generera de största plantorna och innefattar därför högre prestanda jämfört med andra hydroponiska hemmasystem. Användning av substrat eliminerades också vilket minskar kontinuerlig materialkonsumption inom hydroponik.

Texte intégralRésumé :
This work is presented in defence of the thesis that it is possible to measure the social expectations and perceptions that humans have of robots in an explicit and succinct manner, and these measures are related to how humans interact with, and evaluate, these robots. There are many ways of understanding how humans may respond to, or reason about, robots as social actors, but the approach that was adopted within this body of work was one which focused on interaction-specific expectations, rather than expectations regarding the true nature of the robot. These expectations were investigated using a questionnaire-based tool, the University of Hertfordshire Social Roles Questionnaire, which was developed as part of the work presented in this thesis and tested on a sample of 400 visitors to an exhibition in the Science Gallery in Dublin. This study suggested that responses to this questionnaire loaded on two main dimensions, one which related to the degree of social equality the participants expected the interactions with the robots to have, and the other was related to the degree of control they expected to exert upon the robots within the interaction. A single item, related to pet-like interactions, loaded on both and was considered a separate, third dimension. This questionnaire was deployed as part of a proxemics study, which found that the degree to which participants accepted particular proxemics behaviours was correlated with initial social expectations of the robot. If participants expected the robot to be more of a social equal, then the participants preferred the robot to approach from the front, while participants who viewed the robot more as a tool preferred it to approach from a less obtrusive angle. The questionnaire was also deployed in two long-term studies. In the first study, which involved one interaction a week over a period of two months, participant social expectations of the robots prior to the beginning of the study, not only impacted how participants evaluated open-ended interactions with the robots throughout the two-month period, but also how they collaborated with the robots in task-oriented interactions as well. In the second study, participants interacted with the robots twice a week over a period of 6 weeks. This study replicated the findings of the previous study, in that initial expectations impacted evaluations of interactions throughout the long-term study. In addition, this study used the questionnaire to measure post-interaction perceptions of the robots in terms of social expectations. The results from these suggest that while initial social expectations of robots impact how participants evaluate the robots in terms of interactional outcomes, social perceptions of robots are more closely related to the social/affective experience of the interaction.
