Increasing economic, social and environmental problems around the world have shown that current models of economic development cannot be sustained. Thus, new patterns of consumption are needed. According to the literature, global companies are well placed to attempt leveraging sustainable consumption, as their production lines; supply chains; products and services extend across many continents, and as such the cumulative effect of their actions are wide reaching. This research sets out to better understand the intertwined factors that companies in two different contexts (Mexico and the UK), need to consider in order to leverage sustainable consumption. Through the literature review it was seen that sustainable consumption requires a multitude of changes, which have to occur at a systems level. In response to this, user-centred design (UCD) principles were seen as a valuable approach to give a broader account of the complexities around consumption and consumer's behaviour that could be communicated to higher management. A series of interviews, a focus group and a document analysis was undertaken to collect qualitative data. The findings led to the construction of a theoretical framework supported by UCD principles. The theoretical framework was then translated into the Sustainable Consumption Leveraging (SCL) Model and its toolkit. The SCL Model is a mechanism that takes into account the interaction of elements in a specific business context to identify areas of opportunity to leverage sustainable consumption through a consumer-focused approach. During a series of workshops, the SCL Model and its toolkit were tested to distinguish further opportunities of improvement and to understand where global companies stand with regards leveraging sustainable consumption. The research concludes by saying that companies need to work in collaboration with other actors to build a strong sustainability and innovation strategy that could help them to find new ways of doing business that can enhance more sustainable lifestyles.

Sambandet mellan patienters förväntningar inför axeloperation och i vilken utsträckning dessa påverkar den upplevda nöjdheten är inte entydigt. Positiva förväntningar är viktiga samtidigt som orealistiskt höga förväntningar kan ge lägre patientnöjdhet. Uppföljning utifrån individens upplevelse är viktig för att följa resultat och öka patientnöjdheten i en personcentrerad vård. Syftet med denna studie var att redogöra för en grupp axelopererade patienters mål inför operation, måluppfyllelse efter ett år och undersöka eventuella samband mellan olika förväntningar och grad av måluppfyllelse. Syftet var också att beskriva upplevd livskvalitet före och ett år efter operation, korrelera skattad livskvalitet och måluppfyllelse efter ett år samt undersöka eventuella skillnader i skattade värden beroende på bakgrundsfaktorer. Metoden var en  korrelerande prospektiv registerbaserad studie. Huvudresultatet visade hög grad av patientnöjdhet både för skattad livskvalitet och uppfyllelse av personligt mål, sambandet mellan dessa värden var starkt. Smärtfrihet var den vanligaste förhoppningen. Signifikant samband mellan olika förväntningar och uppnått mål sågs i grupperna ¨återgå till arbete¨ och ¨smärtfri nattetid¨. Kvinnor skattade signifikant lägre värden än män före operation men ingen signifikant skillnad kan ses vid ettårsuppföljningen. Slutsatsen var att undersökningsgruppen inför operation hade höga förväntningar och att dessa i stor utsträckning uppnåtts. Likaså sågs tydlig ökning i skattad livskvalitet. Minskad smärta/smärtfrihet var tydligt den viktigaste förväntan inför operation. Denna utvärdering av patientens upplevelse av måluppfyllelse och livskvalitet kan ge återkoppling i arbetet för att stärka och utveckla en personcentrerad vård. / The correlation between the expectations before shoulder surgery and to which extent they affect patient satisfaction is not unambiguous. Positive expectations are important whilst unrealistic expectations could lead to reduced patient satisfaction. Follow up based on the experiences of the individual is important to follow results and increase patient satisfaction in a person centred care. The aim of this study was to narrate the preoperative goals and the fulfilment of these goals after one year for a group of patients who had undergone shoulder surgery and to investigate the eventual relationship between different expectations and degree of goal fulfilment. The aim was also to describe the perceived life quality before and one year after surgery, to correlate perceived life quality and goal fulfilment after one year and to examine eventual differences in assessed values due to demographic factors. The method was a correlative prospective register based study. The main result showed high degree of patient satisfaction for both assessed life quality and fulfilment of personal expectations, the correlation between these values where strong. Relief of pain was the most common expectation. Significant correlation between expectations and goal assessment where seen in the groups ¨return to work¨ and ¨relief of nocturnal pain¨. Women assessed significant lower values than men before operation but no significant differences where seen at the follow-up after one year. The conclusion was that the study population had high preoperative expectations and that these where fulfilled to a great extent. An explicit increase in perceived life quality was also seen. Relief or reduction of pain was clearly the most important expectation before surgery. This evaluation of patients’ sense of goal fulfilment and perceived life quality might give feed back in the work to strengthen and generate a person centred approach.

Emotions are fundamental to human lives and decision-making. Understanding and expression of emotional feeling between people forms an intricate web. This complex interactional phenomena, is a hot topic for research, as new techniques such as brain imaging give us insights about how emotions are tied to human functions. Communication of emotions is mixed with communication of other types of information (such as factual details) and emotions can be consciously or unconsciously displayed. Affective computer systems, using sensors for emotion recognition and able to make emotive responses are under development. The increased potential for emotional interaction with products and services, in many domains, is generating much interest. Emotionally enhanced systems have potential to improve human computer interaction and so to improve how systems are used and what they can deliver. They may also have adverse implications such as creating systems capable of emotional manipulation of users. Affective systems are in their infancy and lack human complexity and capability. This makes it difficult to assess whether human interaction with such systems will actually prove beneficial or desirable to users. By using experimental design, a Wizard of Oz methodology and a game that appeared to respond to the user's emotional signals with human-like capability, I tested user experience and reactions to a system that appeared affective. To assess users' behaviour, I developed a novel affective behaviour coding system called 'affectemes'. I found significant gains in user satisfaction and performance when using an affective system. Those believing the system responded to emotional signals blinked more frequently. If the machine failed to respond to their emotional signals, they increased their efforts to convey emotion, which might be an attempt to 'repair' the interaction. This work highlights how very complex and difficult it is to design and evaluate affective systems. I identify many issues for future work, including the unconscious nature of emotions and how they are recognised and displayed with affective systems; issues about the power of emotionally interactive systems and their evaluation; and critical ethical issues. These are important considerations for future design of systems that use emotion recognition in computing.

Recent, innovative developments in the field of gesture interfaces as input techniques have the potential to provide a basic, lower-cost, point-and-click function for graphic user interfaces (GUIs). Since these gesture interfaces are not yet widely used, indeed no tilt-based gesture interface is currently on the market, there is neither an international standard for the testing procedure nor a guideline for their ergonomic design and development. Hence, the research area demands more design case studies on a practical basis. The purpose of the research is to investigate the design factors of gesture interfaces for the point-andclick task in the desktop computer environment. The key function of gesture interfaces is to transfer the specific body movement into the cursor movement on the two-dimensional graphical user interface(2D GUI) on a real-time basis, based in particular on the arm movement. The initial literature review identified limitations related to the cursor movement behaviour with gesture interfaces. Since the cursor movement is the machine output of the gesture interfaces that need to be designed, a new accuracy measure based on the calculation of the cursor movement distance and an associated model was then proposed in order to validate the continuous cursor movement. Furthermore, a design guideline with detailed design requirements and specifications for the tilt-based gesture interfaces was suggested. In order to collect the human performance data and the cursor movement distance, a graphical measurement platform was designed and validated with the ordinary mouse. Since there are typically two types of gesture interface, i.e. the sweep-based and the tilt-based, and no commercial tilt-based gesture interface has yet been developed, a commercial sweep-based gesture interface, namely the P5 Glove, was studied and the causes and effects of the discrete cursor movement on the usability was investigated. According to the proposed design guideline, two versions of the tilt-based gesture 3 interface were designed and validated based on an iterative design process. Most of the phenomena and results from the trials undertaken, which are inter-related, were analyzed and discussed. The research has contributed new knowledge through design improvement of tilt-based gesture interfaces and the improvement of the discrete cursor movement by elimination of the manual error compensation. This research reveals that there is a relation between the cursor movement behaviour and the adjusted R 2 for the prediction of the movement time across models expanded from Fitts’ Law. In such a situation, the actual working area and the joint ranges are lengthy and appreciably different from those that had been planned. Further studies are suggested. The research was associated with the University Alliance Scheme technically supported by Freescale Semiconductor Co., U.S.

In order to make technology easier to handle for its users, the field of HCI (Human- Computer Interaction) has recently often turned the environment and the context of use. In this thesis the focus is on the relation between the user and the technology. More specifically, this thesis explores how roles and professional identity effects the use and views of the technology used. The exploration includes two different domains, a clinical setting and a media production setting, where the focus is on the clinical setting. These are domains that have strong professional identities in common, in the clinical setting neurosurgeons and physicists, and the media setting journalists. These settings also have a strong technological profile, in the clinical setting the focus has been on a specific neurosurgical tool called Leksell GammaKnife and in the journalistic setting the introduction of new media technology in general has been in focus. The data collection includes interviews, observations and participatory design oriented workshops. The data collected were analyzed with qualitative methods inspired by grounded theory. The work with the Leksell GammaKnife showed that there were two different approaches towards the work, the tool and development, depending on the work identity. Depending on if the user were a neurosurgeon or a physicist, the definition of the work preformed was inline with their identity, even if the task preformed was the same. When it comes to the media production tool, the focus of the study was a participatory design oriented development process. The outcome of the process turned out to be oriented towards the objectives that were inline with the users identity, more than with the task that were to be preformed. At some level, even the task was defined from the user dentity.

Program evaluation is becoming increasingly important in pediatric rehabilitation settings that adhere to FCS philosophy. This philosophy recognizes that each family is unique, that parents know their children best, and that optimal child functioning occurs within a family context. However, researchers know little about the specific evaluation activities occurring in these settings or the extent to which evaluators uphold FCS philosophy in their activities. The primary goal of this study is to examine the strengths, limitations, and consequences of current evaluation practice, including its compatibility with FCS philosophy. As a secondary goal, the study aims to understand the promise and prospects of alternative evaluation approaches that, in theory, are compatible with FCS philosophy. To address these goals, this study uses a mixed-methods approach and includes three phases. Phase 1 involves a survey of staff members involved with program evaluation at 15 Canadian pediatric rehabilitation centres. It determines the level of program evaluation occurring in these settings, verifies on the motivation for evaluation, and describes the degree to which evaluation activities are consistent with the FCS philosophy. Phase 2 involves interviews with staff members and explores the values, factors, and conditions that support and inhibit the evaluation of family-centred programs in pediatric rehabilitation settings as well as the benefits and limitations of using mainstream practices for evaluating these programs. Phase 3 then uses focus groups with staff members and interviews with parents to explore how the evaluation of family-centred programs can be improved as well as to identify the compatibility and practicality of using alternative evaluation approaches within these settings. Overall, the findings show that the amount of evaluation activities occurring within these centres is variable; that the majority of individuals working in program evaluation do not have formal training in it; and that the centres have limited resources for evaluation. The findings also demonstrate that participatory evaluation approaches are more compatible with FCS philosophy but that it might be difficult to implement such approaches given the limited resources and diverse characteristics of rehabilitation settings. In light of these circumstances, the study notes ways for improving program evaluation activities.

Aims: Acquired Brain Injury (ABI) is often researched from a reductionist perspective, focusing on pathology and dysfunction (Olney & Kim, 2001). More recently there has been a call towards taking a person-centred, global approach; questioning old ‘assumptions’ about what is currently known, and incorporating the views of the patient (Hill, 1999). This qualitative research study aimed to make a further contribution to the evidence-base by investigating the experience of adjusting to life after ABI. Method: Six participants, (two female, four male) aged 26-49, who had experienced a severe ABI an average of 31 months previously, were interviewed using a semistructured schedule. Interpretative Phenomenological Analysis (IPA) was employed to analyse the transcripts. Results: Five master themes emerged from the participants’ accounts: Experiencing a loss of control; Observed changes as a threat to identity; Being displaced by the injury: Feeling unchanged in a changed world; Attempts at managing a threatened identity, and Enable me don’t disable me: The role of support in recovery. Implications: Clinical implications were considered within Bronfenbrenner’s (1979, 2004) Ecological Systems Theoretical Framework. Within the Microsystems (the individual’s immediate systems such as their body, home and work) participants described a struggle to make sense of their perceived loss of control of their body and brain. They described the importance of making sense of these changes. Clinically there is a potential role for professionals to facilitate how people make sense of their experiences, perhaps moving away from reductionist explanations, which appeared to prevent participants from having hope to influence change. From a Macrosystemic level (the individual’s social, cultural and political systems) the participants felt they were less valued and as a result, judged by society and by political systems. Participants’ accounts suggested that they wanted to continue to contribute and be valuable in society. An implication therefore is for professionals involved to take more a political stance in influencing how we currently conceptualise people after brain injury, focusing on enablement rather than disablement.

User-Centred Design (UCD) was proposed in the 1980s and, since then, its philosophy has helped to solve design problems, regardless of the advances in technology over time. The standard ISO 9241:210 (2010), formerly ISO 13407, provides guidance in human-centred design principles and activities undertaken throughout the design lifecycle to further support UCD. In addition, since it was mentioned in ISO 9241:210, UCD has also utilised User Experience Design (UXD) in recent years. There are many approaches that support UCD to ensure it is more attainable when designing. In addition, large firms, such as HP, IBM and Microsoft, use anthropologists in their user research in order to make products more user-centred. However, the concept of UCD should, theoretically, be more widely used in all product design and it is intriguing as to why it is not as popular as it should be. As noticed in the real world, imperfect designs still frustrate us everywhere. The aims of this thesis were to investigate the difficulties of practicing a UCD approach in idea generation and to design solutions for idea generation that would encourage further practice of UCD/UXD. In the first part of the thesis, there is an exploration of the problems encountered when practicing UCD idea generation. When examining the process, a multitude of problems were found, with most blamed as being costly, time consuming and requiring complex skills. In addition, it was suggested that a systematic solution was required to overcome such difficulties. Therefore, later in this research, a systematic model is proposed and evaluated using participants (both designers and target users). Due to the fact that design practitioners are not usually researchers, further help to implement the model in the form of persona application software is needed. Hence, the concept of service design was employed to further assist with the use of the model. In the end, computer-aided development was introduced, together with the integration of the systematic UCD model. The UCD model and the software have been evaluated as effective from both the responses of product design practitioners and end-users. Future recommendations and the research limitations are also discussed in each chapter and the overall results are given in the last chapter. This thesis successfully provided the complete process during the exploration of the low usage problems of UCD, and solutions were presented to assist designers with their UCD/UXD in the future.

At large sporting events (LSEs), e.g. football matches and athletics events, the user experience has been shown to be highly variable (Nilsson, 2004; Nilsson et al. 2004). Reported problems include a lack of social interaction with fellow spectators, and insufficient relevant information on the events or the sporting action taking place (Nilsson, 2004; Nilsson et al. 2004; Esbjornsson et al. 2006; Jacucci et al. 2005). A possible solution is personalisation, making the mobile application adapt to the user, ensuring that only relevant information is retrieved and presented in a way that is suitable. This thesis is devoted to studying the user experience related to mobile personalization at LSEs. It aims to investigate how personalized mobile applications at LSEs can render the user experience more active and engaging in a contextually, socially and culturally relevant way. The thesis reviews different theoretical approaches to help to understand the concepts of interest e.g. personalization and user experience (Chapter 2). Research methods are also discussed including the challenge of adapting user-centred methods into the Chinese culture (Chapter 3). This thesis investigates the user experience of mobile personalization at LSEs by following the circle of user-centred research: It starts to consider user requirements and user experience at LSEs and derives the usage patterns that personalized mobile applications could usefully support (Chapter 4). Then it explores the relevant contextual factors at LSEs which could be used to prescribe the behaviour of a personalizable mobile application (Chapter 5). Next, it describes the user-centred process used to design personalizable interfaces for mobile applications used at LSEs. Four key elements of design are considered: content, conceptual, interaction and presentation design (Chapter 6). The final outputs of the design process were two personalized mobile prototypes for Chinese users at LSEs. These included versions based on either (1) user-initiated or (2) system-initiated personalisation. Finally it investigates the impact on user experience of mobile personalization at LSEs in two empirical studies (a field experiment and a lab-based experiment) with these prototypes (Chapters 7 and 8). Mobile personalization is shown to result in an enriched user experience across a range of activities that a spectator would undertake at a large sporting event. The thesis discusses primarily the effective design of mobile personalization, the design implications at LSEs, user experience design, and research methods for Chinese users (Chapter 9). In conclusion (Chapter 10), specific contributions and avenues for future work are highlighted.

Pakistani families with disabled children are among the most disadvantaged population groups in the UK. Previous research has indicated difficulties with accessing support services as well as problematic attitudes towards disability within the Pakistani community. As no substantial improvement in their situation was evidenced since early studies in the 1990s, a participatory action research study was undertaken with six Pakistani families to explore how an actionoriented, emancipatory approach could facilitate them to explore their support needs and how these might be met, in further depth. An occupational justice perspective was used to clarify how cultural and familial expectations influenced family members’ occupational balance and well-being. After an exploratory phase in which all family members were interviewed and family interactions observed in their own homes, three action research groups were formed for women, men and children respectively. Each group carried out their own action research around their chosen topic. Through participation in the project the participants gained important skills as well as a better understanding of their situation and how they could be more proactive in improving it. Furthermore, the fact that all family members were actively involved in the project helped them to start implementing changes in behaviour and communication at home. Key findings of the study were that the importance of faith in accepting the disabled child and dealing with negative community attitudes needs to be recognised and fostered; that the social model of disability needs to be more explicit about the influence of religion and culture on the lived experience of disabled people; that the central support need of parents is for practitioners to build up a supportive relationship with them as persons in their own right; and that (the lack of) belongingness had a very significant impact on the disabled child’s and their mothers’ well-being.
