    Portraying Empathy In Character Design2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis examines possible improvement in evoking empathy through character design. The method used is research by design, by gathering information about emotions, emotional- and character design, and applying it during the design phase, two new characters were created based on an existing game character. The evaluation was done through a survey which concluded that the re-designed characters ability in evoking empathy was significantly stronger than the original characters. The characters ability in evoking empathy improved because they were more distinct when it came to expressing emotions through facial features and body language.

    Usability of the Swedish Accessible Electronic Health Record: Qualitative Survey Study.2022In: JMIR Human Factors, E-ISSN 2292-9495, Vol. 9, no 2, article id e37192Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Patient portals are increasingly being implemented worldwide to ensure that patients have timely access to their health data, including patients' access to their electronic health records. In Sweden, the e-service Journalen is a national patient-accessible electronic health record (PAEHR), accessible on the web through the national patient portal. User characteristics and perceived benefits of using a PAEHR will influence behavioral intentions to use and adoption; however, poor usability, which increases effort expectancy, may have a negative impact. Therefore, it is of interest to further explore how users of the PAEHR Journalen perceive its usability and usefulness.

    OBJECTIVE: On the basis of the analysis of the survey respondents' experiences of the usability of the Swedish PAEHR, this study aimed to identify specific usability problems that may need to be addressed in the future.

    METHODS: A survey study was conducted to elicit opinions and experiences of patients using Journalen. Data were collected from June to October 2016. The questionnaire included a free-text question regarding the usability of the system, and the responses were analyzed using content analysis with a sociotechnical framework as guidance when grouping identified usability issues.

    RESULTS: During the survey period, 423,141 users logged into Journalen, of whom 2587 (0.61%) completed the survey (unique users who logged in; response rate 0.61%). Of the 2587 respondents, 186 (7.19%) provided free-text comments on the usability questions. The analysis resulted in 19 categories, which could be grouped under 7 of the 8 dimensions in the sociotechnical framework of Sittig and Singh. The most frequently mentioned problems were related to regional access limitations, structure and navigation of the patient portal, and language and understanding.

    CONCLUSIONS: Although the survey respondents, who were also end users of the PAEHR Journalen, were overall satisfied with its usability, they also experienced important challenges when accessing their records. For all patients to be able to reap the benefits of record access, it is essential to understand both the usability challenges they encounter and, more broadly, how policies, regulations, and technical implementation decisions affect the usefulness of record access. The results presented here are specific to the Swedish PAEHR Journalen but also provide important insights into how design and implementation of record access can be improved in any context.

    User Evaluation of the Swedish Patient Accessible Electronic Health Record: System Usability Scale2021In: JMIR Human Factors, E-ISSN 2292-9495, Vol. 8, no 3Article in journal (Refereed)
    Abstract [en]

    Background: Transparency is increasingly called for in health care, especially, when it comes to patients’ access to their electronic health records. In Sweden, the e-service Journalen is a national patient accessible electronic health record (PAEHR), accessible online via the national patient portal. User characteristics and perceived benefits of using a PAEHR influence behavioral intention for use and adoption, but poor usability that increases the effort expectancy can have a negative impact. It is, therefore, of interest to explore how users of the PAEHR Journalen perceive its usability and usefulness. Objective: The aim of this study was to explore how the users of the Swedish PAEHR experience the usability of the system and to identify differences in these experiences based on the level of transparency of the region. Methods: A survey study was conducted to elicit opinions and experiences of patients using Journalen. The data were collected from June to October 2016. The questionnaire included questions regarding the usability of the system from the System Usability Scale (SUS). The SUS analysis was the focus of this paper. Analysis was performed on different levels: nationally looking at the whole data set and breaking it down by focusing on 2 different regions to explore differences in experienced usability based on the level of transparency. Results: During the survey period, 423,141 users logged into Journalen, of which 2587 unique users completed the survey (response rate 0.61%). The total mean score for all respondents to the SUS items was 79.81 (SD 14.25), which corresponds to a system with good usability. To further explore whether the level of transparency in a region would affect the user’s experience of the usability of the system, we analyzed the 2 regions with the most respondents: Region Uppsala (the first to launch, with a high level of transparency), and Region Skåne (an early implementer, with a low level of transparency at the time of the survey). Of the participants who responded to at least 1 SUS statement, 520 stated that they had received care in Region Skåne, whereas 331 participants had received care in Region Uppsala. Uppsala’s mean SUS score was 80.71 (SD 13.41), compared with Skåne’s mean of 79.37 (SD 13.78). Conclusions: The Swedish national PAEHR Journalen has a reasonably good usability (mean SUS score 79.81, SD 14.25); however, further research into more specific usability areas are needed to ensure usefulness and ease of use in the future. A somewhat higher SUS score for the region with high transparency compared with the region with low transparency could indicate a relationship between the perceived usability of a PAEHR and the level of transparency offered, but further research on the relationship between transparency and usability is required.

    A comparative study between user research in academia and user research in commercially driven companies2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The following degree project is written within the department of Information Technology at Uppsala University. The subject studied is the difference between academic user research and such user research performed by professionals at commercially driven companies. Academic’s and professional’s agendas, interests and approaches seem to differ and consequently a gap emerges. To perform a comparison between academically defined and practically defined user research a case study and a literature study were conducted. During the literature study three main academic approaches to perform user research were studied and summarized in a unified view. The case study was performed over 4 months at Spotify in the User Research team to gain insights into how user research is conducted in a commercially driven company. The degree project shows that academics and professionals can benefit from each other. For example, academics can integrate various mix methods to better understand design and concepts and base assumptions on more reliable data. Professionals can benefit from academics by adapting a similar systematic approach to perform user research and have a larger impact on the development.

    Heuristic Usability Evaluation of the Uppsala University Student Portal2020Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Heuristic evaluation is a significant method used to evaluate the performance and usability of any web application. This research focuses on the usability evaluation of the Uppsala University student portal using the heuristic evaluation method. A survey was conducted to identify the usability problems in the student portal. The conducted survey determined that most of the participants agreed that the student portal is reliable, but more navigations and shortcuts need to be included so that the users can perform operations effectively. Nielsen’s ten heuristic principles are added in the survey for evaluating the usability of the student portal. For the effectiveness and flexibility of the utilization of the student portal, it is suggested that significant icons and menus are added that can enable the users to select options in less time. It is significant for the student portal to alert the students if any error occurs and provide notification about the errors and problems.

    Future Train Traffic Control: Development and deployment of new principles and systems in train traffic control2012Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The train traffic control system of the future requires new solutions and strategies in order to better meet tomorrow’s demands and goals. Uppsala University and Trafikverket have been collaborating for several years in research regarding train traffic control and how to improve traffic controllers’ support systems and working environment. At an early stage in the collaboration studies and analysis of important aspects of the traffic controller’s tasks, strategies, decision making, use of information and support systems were undertaken. This research resulted in new control paradigms, from control by exception to control by replanning. By using this paradigm we developed and designed prototype systems and interfaces that could better meet future goals and contribute to more optimal use of infrastructure capacity. Based on this research, a new operational traffic control system called STEG was developed in an iterative and user-centred design process. The system was deployed and tested operatively at a train traffic control centre in Sweden. The following evaluations focused on what happens when STEG is introduced in train traffic controllers’ work places. The evaluation of STEG showed satisfied users with a feeling of active involvement during the design and deployment processes, and gave confirmation that the new control strategies are functioning. STEG was seen as successful and was thereafter developed into MULTI-STEG, intended to be used by several users simultaneously, supporting them to share information in a new way. MULTI-STEG was deployed and tested at another train traffic control centre in Sweden. The following evaluations of MULTI-STEG focused on what happens when several users are involved and how train traffic controllers felt when sharing information, that before would have only been in their own minds, with each other. Some complications occurred due to mistakes in the deployment process, but altogether the evaluation showed positive attitudes towards the new system and MULTI-STEG was perceived as an efficient system for train traffic control.

    The main results are that STEG and MULTI-STEG can be used as an efficient train traffic control system and the new system can reduce the unnecessary cognitive load currently placed upon traffic controllers in today’s system. Also the deployment process is fundamental to the acceptance or non-acceptance of a new system by users. STEG was developed in a user-centred design process, but it is important that the deployment process is also user-centred.

    Abstract [en]

    Tomorrow’s train traffic systems requires new strategies and solutions for efficient traintraffic control and utilization of track capacity, especially in traffic systems with a highdegree of deregulated and mixed traffic. There are many different goals associated withthe traffic control tasks and the work of the traffic controllers (dispatchers). Examples aresafety, efficiency of the traffic with regard to timeliness and energy consumption, goodservice and information to passengers and customers etc. Today’s traffic controlsystems and user interfaces do not efficiently support such goals. In earlier research wehave analyzed important aspects of the traffic controller’s tasks, strategies, decisionmaking, use of information and support systems etc. Based on this research we,together with Banverket (Swedish Rail Administration), have designed prototypesystems and interfaces that better can meet future goals and contribute to more optimaluse of infrastructure capacity. These prototype systems have now been developed into afully operational system which has been tested during 6 months, for control of train trafficin a section of the Swedish rail system. The evaluation shows that the system efficientlysupports control tasks and is well accepted by the involved traffic controllers.

    Abstract [en]

    Uppsala University has collaborated with Swedish National Railway Administration in research about train traffic control and how to improve traffic controllers’ work environment, so that they can better meet future demands. This has resulted in a new operational train traffic control system called STEG. The traffic controllers are today forced to develop and use very complex mental models which take a long time to learn. We have also found that their cognitive capacity is more used to indentify, understand and analyze the traffic situation and less to solve problems and find optimal solutions to disturbances. The objective for developing STEG was to change this situation and reduce unnecessary cognitive load. Interviews with traffic controllers show that STEG has reduced the complexity of their mental models and contributed to less unnecessary cognitive load in operation. Our conclusion is that by reducing the complexity of their mental model, they can be skilled much faster and they are now able to use their cognitive capacity and skills on the important parts of their work.

    Designing work-related software and identifying positive practices using a wellbeing-driven approach2023Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this report is to analyze, design and evaluate work-related software using a wellbeing-driven approach. By having the UX-wheel as a base, the focus was to identify practices that the chosen user group found especially meaningful and joyful. This was done by firstly investigating the state of the current version of the software Viedoc. Viedoc is used to design and gather subject data during clinical studies. After analyzing and gathering usage data and positive practices, several design concepts and ideas were brought forward. One of these was then implemented in an interactive prototype. The prototype was evaluated by two users by performing tasks in it and self-reporting using a proposed questionnaire. According to the questionnaire, the prototype did indeed give a feeling of subjective well-being, however, in order to verify this result and the method, more users need to be included.

    Evolving Systems – Engaged Users: Key Principles for Improving Region-wide Health IT Adoption2013Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Many countries have formulated their eHealth visions and billions of dollars have been spent on supporting the eHealth development throughout the world. An important part of the development is the electronic patient record (EPR). To enable sharing and increase cooperation between care providers, most Swedish county councils have decided to use a region-wide EPR. The health professionals often experience numerous problems and consider the region-wide EPR to be too generic and require them to tailor their practices instead of the system evolving towards supporting their needs.

    The aim of the PhD research is to gain knowledge of adoption when deploying and using region-wide health IT systems. This is accomplished by studying, analysing and reflecting upon what region-wide health IT systems are and how professionals use them in their practice. In the research a grounded theory method has been used, which means that the empirical data, not theories and hypotheses, have driven the research process. The data-gathering methods have been interviews, observations, participating in meetings, questionnaires, seminars and conducting literature reviews.

    In order to be able to improve the adoption, a set of four key principles has been identified: (1) Evolving systems-Engaged users, (2) Treat IT deployment and usage as part of organisational development, (3) Identify, respect and support differences, and (4) Identify what must be customised and what can be centralised.

    These four principles challenge the traditional way of developing enterprise-wide IT and emphasise the importance that users must engage in the development, procurement and deployment process to identify their similar and unique needs and procedures. It is crucial that both the similarities and uniqueness are respected and supported. The similarities can be supported by a centralised, standardised solution, while uniqueness requires a customised solution. In order to accomplish that, the IT deployment and usage needs to be treated as an important part of the on-going organisational development, and the IT systems must evolve, i.e., be continuously developed in order to engage the users to participate.

    Abstract [en]

    This paper is based on an interview study with 19 resident, specialist and senior physicians. The study was initiated by a Swedish Hospital management to investigate physicians’ attitude towards their EPR (Electronic Patient Records) and give recommendations for improvement in organization, development, deployment and training. The management had experienced that the physicians were unwilling to take part in the EPR deployment process and simultaneously complained about the low usability and potential safety risks of the systems. The study shows that the EPR must be considered a shared responsibility within the whole organization and not just a property of the IT department. The physicians must consider, and really experience, EPR as efficient support in their daily work rather than something they are forced to use. This includes considering work with the EPR as an important part of their work with patients.

    In this paper we use a sociotechnical approach and theories about group processes to analyse how two main clinician groups, nurses and physicians, are influenced by their main IT tool, the Electronic Patient Record (EPR), in their clinical practice. The paper is based on interviews with 19 physicians and 17 nurses that work at a Swedish university hospital. The clinicians considered the use of an EPR system necessary, but experienced the need to change their clinical practice to less efficient work routines in order for the EPR system to support them. The main result of the paper is that the EPR system affected nurses and physicians differently. The physicians were more frustrated and experienced that the EPR system worsened their clinical practice and a decreased status among the other clinical professions. The nurses on the other hand experienced that their work became more visible than before and found it easier to claim the importance of their work towards the physicians.

    Abstract [en]

    The health care environment is unique because of the large and complex organisation with a traditional hierarchic structure that is governed by laws and regulations. This paper examines how a large Swedish health care organisation work with usability issues regarding Electronic Patient Record (EPR) deployment and usage. EPR systems have great impact on work environment and clinical work routines will not be performed in the same way as before. This paper analyse how the EPR management and core business understand their EPR responsibilities and work with usability aspects at different levels in the organisations. The paper reveals that there is a conflict about responsibility between EPR management and core business management. The reasons for the confusion are contradictive understanding of what an EPR system is, an IT system or a tool for the core business to perform better health care work. This leads to that care staff's experience regarding the EPR system's usability, is not being listened to within the organisation. Three key concerns for a successful EPR deployment and usage are identified and further analysed; education, evaluation and support & improvement ideas.

    Abstract [en]

    This paper presents a longitudinal evaluation of user adoption during a Patient Administrative System (PAS) deployment. The research was performed at three units within a Swedish university hospital. Both qualitative and quantitative methods have been used to gather data before, during and up to two years after the deployment. The results show that all users experienced usability problems. After two years of usage the system was still not considered to be as supportive as the old system. The users that were required to use the system felt unsure and stressed about whether all information was consulted or not. The users that were less dependent on the system solved the problems by not doing the tasks; instead they let the clerks continue to do the PAS tasks as they did before the deployment. The results indicate that time will not heal usability problems; instead they need to be addressed in other ways.

    Abstract [en]

    BACKGROUND:

    In Sweden there are modular region-wide EPR systems that are implemented at various health organisations in the region. The market is dominated by four IT systems that have been procured and deployed in 18 out of 21 regions.

    METHODS:

    In a 2.5-year research study, deployments of three region-wide EPR modules: a patient administration system, eReferral module and eMedication module were followed and evaluated. Health professionals, EPR maintenance organisation, IT and health care managers were observed, interviewed and responded to questionnaires.

    RESULTS:

    Although the same deployment process was used during the three deployments, large variations in the units' adoptions were observed. The variations were due to: (1) expectation and attitude, (2) management and steering, (3) end-user involvement, (4) EPR learning, and (5) usability and the possibility of changing and improving the EPR.

    CONCLUSIONS:

    If changes in work processes are not considered in development and deployment, the potential benefits will not be achieved. It is therefore crucial that EPR deployment is conceived as organisational development. Users must be supported not just before and during the go-live phase, but also in the post-period. A problem often encountered is that it is difficult to make late changes in a region-wide EPR, and it is an open question whether it is possible to talk about a successful deployment if the usability of the introduced system is low.

    Abstract [en]

    The paper presents secondary users interpretation of key concerns (KC) for achieving an efficient and effective electronic patient record (EPR) usage. The evaluation is based on twelve interviews with Clinical Directors and IT Directors that are responsible for delivering high quality care, procuring and implementing IT. The participants represented five Swedish county councils who all use a region-wide EPR for all primary and hospital services. The analysis indicated that there were an unresolved conflict regarding what influence the IT should have on how the health professionals performed practice. Either the systems’ usability or the health professionals unwillingness to change, were blamed for the problems. We argue that the conflict is based on the idea that one EPR is going to support all user groups. Using a region-wide EPR must not be a problem. In the studied organisations, however, it became a problem because to achieve “one system that fits all” the fact that different user groups had different needs, roles and responsibilities were neglected. Neglecting the users’ needs is not solving the problems; instead it will increase the conflict. Using the KC will shed light on differences between primary and secondary users interpretations of the aim of the region-wide EPR.

    Abstract [en]

    Purpose The New Zealand eHealth landscape is diverse with hundreds of systems ‘wired together’ in a complex puzzle. The purpose of this paper is to explore the current debate about selecting and using Best of Breed (BoB) or Enterprise-wide (EW) eHealth systems.

    Method Strategic eHealth documents were analysed and 14 senior IS executives from health and IT organisations were interviewed.

    Findings There appears to be agreement about: (1) what the concepts mean; (2) the problems caused by the mix of BoB and EW, e.g., the strong influence of clinicians on IT decision making; and (3) a possible solution to the complex puzzle lies in changing the mix to emphasise patient-centric eHealth. However, when discussing to what degree IT systems should be customised and/or centralised disagreements become visible.

    Discussion and conclusions There is a trend among decision-makers towards patients’ needs rather than the physical context in deciding system use and design, with an emphasis on what is considered to be ‘best practice’. In this process the preferred systems are EW, however it is important to remember that it is not the only option. There is a risk that if the IT system is too generic (centralised) it might be an unsupportive tool for clinicians and undermine its purpose.

    Tailor the system or tailor the user?: How to make better use of electronic patient record systems2011Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Health care organisations are extremely complex because they consist of heterogeneous groups of people (clinical professions, patients, managers), use advanced technology (medical devices and patient record systems), and apply many organisational and clinical routines. When introducing Electronic Patient Record systems (EPR) in health care organisations, all these aspects get affected. Using a sociotechnical perspective is necessary in order to get a "successful" EPR usage.

    The aim of my PhD studies is to provide health care organisations with knowledge and insights into how they can improve their organisation and practice in relation to usage of EPR systems. In my research I have used a grounded theory methodology for studying, analysing and reflecting on how electronic patient record systems are used by professionals in their practice. Studies have been conducted during a 2.5 years collaborative research project. Within the studied health care organisation there are differing opinions if an EPR system is mainly a technical system or a tool to support the clinical organisation. This conceptual division leads to an uncertainty in who is responsible for the proper function of the EPR system and have a major effect for the clinicians in their clinical practice. During the research seven potential problems areas, mandate, usability, education, participation, improvements, support and evaluation have been identified as crucial for the health care organisation to manage to achieve an effective EPR usage.

    The main results are 1) The health care organisation needs to establish a problem-solving strategy that questions the reasons behind the problems occurred, 2) The different stakeholder groups need to interact, create a better understanding for each other's perspective and agree on the same goal for the EPR system, 3) The clinical organisation needs help to improve their clinical practice in relation to the EPR system, 4) The EPR deployment and usage affect the clinicians in different ways. Their attitude towards the EPR system is dependent on the usability of the EPR system, the deployment process, their experience of participation, education, support and possibilities to improve the system.

    Physicians' concept of time usage: A key concern in EPR deployment2010Conference paper (Refereed)
    Abstract [en]

    This paper is based on an interview study with 19 resident, specialist and senior physicians. The study was initiated by a Swedish Hospital management to investigate physicians’ attitude towards their EPR (Electronic Patient Records) and give recommendations for improvement in organization, development, deployment and training. The management had experienced that the physicians were unwilling to take part in the EPR deployment process and simultaneously complained about the low usability and potential safety risks of the systems. The study shows that the EPR must be considered a shared responsibility within the whole organization and not just a property of the IT department. The physicians must consider, and really experience, EPR as efficient support in their daily work rather than something they are forced to use. This includes considering work with the EPR as an important part of their work with patients.

    Evaluation of User Adoption during Three Module Deployments of Region-wide Electronic Patient Record Systems2014In: International Journal of Medical Informatics, ISSN 1386-5056, E-ISSN 1872-8243, Vol. 83, no 6, p. 438-449Article in journal (Refereed)

    BACKGROUND:

    In Sweden there are modular region-wide EPR systems that are implemented at various health organisations in the region. The market is dominated by four IT systems that have been procured and deployed in 18 out of 21 regions.

    METHODS:

    In a 2.5-year research study, deployments of three region-wide EPR modules: a patient administration system, eReferral module and eMedication module were followed and evaluated. Health professionals, EPR maintenance organisation, IT and health care managers were observed, interviewed and responded to questionnaires.

    RESULTS:

    Although the same deployment process was used during the three deployments, large variations in the units' adoptions were observed. The variations were due to: (1) expectation and attitude, (2) management and steering, (3) end-user involvement, (4) EPR learning, and (5) usability and the possibility of changing and improving the EPR.

    CONCLUSIONS:

    If changes in work processes are not considered in development and deployment, the potential benefits will not be achieved. It is therefore crucial that EPR deployment is conceived as organisational development. Users must be supported not just before and during the go-live phase, but also in the post-period. A problem often encountered is that it is difficult to make late changes in a region-wide EPR, and it is an open question whether it is possible to talk about a successful deployment if the usability of the introduced system is low.

    FlyTracker: Design and Implementation of an Interactive Motion Tracking System2014Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    At the department of neuroscience at Uppsala University one of the research groups

    are working with motion vision. Motion vision is how seeing animal species process

    moving objects in their visual fields and how they experience self motion by

    generating an optic flow. This is important for animals of all sizes, everything from

    large mammals to insects. At the neuroscience department at Uppsala University they

    are using flies in their research as these are easier to work with than larger animals.

    Behavioral output as a result of visual stimuli is what is studied in the project I have

    been involved in as a part of this thesis. This is done by a track ball setup. The setup

    consists of a cup with a light plastic ball in it, from the bottom of the cup light airflow

    is added to reduce friction between the ball and the cup. A fly is tethered on top of

    the ball in such a way that when the fly is trying to walk the ball instead rotates

    accordingly. The ball rotation can then be measured by two sensors, both of which

    have been extracted from an optical mouse.

    There is no available, ready-made, software for reading the raw mouse data from the

    two sensors and from that input reconstructs the virtual movement path of the fly

    using. Therefore the purpose of this thesis has been to design and implement a user

    friendly and functional software system that fulfill this requirement.

    The design was done according to the principles of user-centered system design

    although with less formal documentation. This proved to generate a very good result.

    The end-users were included in every phase of the development process and it really

    was a huge advantage for the development process. Although all of the methods made

    available by the theories were not followed religiously, especially regarding

    documentation, that just displayed the power of agile methods were quality is more

    important than documentation. And the evaluation at the end of the project showed

    that the level of usability was high.

    Usable IT systems for mobile work2005Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Today, mobile technology is making its entry into working life within all sorts of occupations. When the purpose of the technology is to support mobile work, new requirements appear – for both the technology itself and for the emerging new work processes – as a result of these new conditions. Consequently, the introduction of a new IT system will affect the organisation and the way work is performed. This thesis addresses these changes in work processes and ways to provide a supporting IT system. An underlying component of my research work is the belief that the personnel from the organisation itself must participate in a large extent when developing new work processes and when designing supporting IT systems, since they will be using the IT system as a tool in their future work practice.

    To understand the nature of mobility in a work context and how it affects usability in IT systems, I have initiated studies of the area where mobile work is supported by technology. Important characteristics have been found that affect mobile work. My research work has concerned traditional professions, primarily professions within mobile healthcare.

    An exhaustive study of how to design new work processes within the area of home care of the elderly has been carried out, accompanied by field studies of mobile work within the mobile healthcare sector. The results have been described in terms of aspects of future work processes that are effective and sustainable. Moreover, important characteristics of mobile technology that support this kind of mobile work have been identified. The two perspectives are then merged, in order to design usable IT systems for mobile work.

    Usability in Mobile IT systems2005Report (Other (popular scientific, debate etc.))
    Abstract [en]

    In this report we give an overview of usability aspects applicable to mobile devices and systems. A number of research projects from three different application areas are presented and experiences from the projects are discussed.

    To successfully design usable products, services and systems both for leisure and for mobile work practice has turned out to be a difficult undertaking. Many systems fail because of a number of reasons. Some systems do not fail, but remains difficult and cumbersome to use.

    A certain immaturity can be observed since developers and designers do not fully utilise the benefits and assets provided by today’s technology in design of mobile systems. For mobile systems, the varying contexts of use become more important. When only relying on existing knowledge of design for stationary systems, important possibilities are often lost and the system has gone astray.

    Co-Designing with Extreme Users: A Framework for User Participation in Design Processes2023In: Scandinavian Journal of Disability Research, ISSN 1501-7419, E-ISSN 1745-3011, Vol. 25, no 1, p. 418-430Article in journal (Refereed)
    Abstract [en]

    The demand for user participation in design processes is increasing, and there is a need to formulate guidance on how to involve disabled users and their representative organisations. Their participation contributes an extreme user perspective to the design process. The aim of this study was to develop an empirically grounded framework for user participation in co-design processes, involving the users with wide range of characteristics. The study was theoretically grounded in 'participatory design' and 'value sensitive design' and used an exploratory study design with online workshops to iteratively collect and analyse data. All participants collaborated on an online Miro-board to identify themes and formulate guiding principles for the framework. We propose a framework consisting of three themes: participation fundamentals, participation ethics and participation practicalities, entailing 11 guiding principles. By applying this framework, the premises, methods and activities in the design process will be accessible to all participants, and user participation in design projects will become more transparent, equitable and easier to implement. It will enable all users, people with disabilities and others, to participate and contribute to a design that can be used by the widest range of people.

    Adaptive robotic tutors that support self-regulated learning: A longer-term investigation with primary school children2018In: International Journal of Social Robotics, ISSN 1875-4791, E-ISSN 1875-4805, Vol. 10, no 3, p. 357-370Article in journal (Refereed)
    Abstract [en]

    Robots are increasingly being used to provide motivating, engaging and personalised support to learners. These robotic tutors have been able to increase student learning gain by providing personalised hints or problem selection. However, they have never been used to assist children in developing self regulated learning (SRL) skills. SRL skills allow a learner to more effectively self-assess and guide their own learning; learners that engage these skills have been shown to perform better academically. This paper explores how personalised tutoring by a robot achieved using an open learner model (OLM) promotes SRL processes and how this can impact learning and SRL skills compared to personalised domain support alone. An OLM allows the learner to view the model that the system holds about them. We present a longer-term study where participants take part in a geography-based task on a touch screen with adaptive feedback provided by the robot. In addition to domain support the robotic tutor uses an OLM to prompt the learner to monitor their developing skills, set goals, and use appropriate tools. Results show that, when a robotic tutor personalises and adaptively scaffolds SRL behaviour based upon an OLM, greater indication of SRL behaviour can be observed over the control condition where the robotic tutor only provides domain support and not SRL scaffolding.

    Exploring the referral and usage of science fiction in HCI literature2018In: Design, User Experience, and Usability: Part II, Springer, 2018, p. 19-38Conference paper (Refereed)
    Abstract [en]

    Research on science fiction (sci-fi) in scientific publications has indicated the usage of sci-fi stories, movies or shows to inspire novel Human-Computer Interaction (HCI) research. Yet no studies have analysed sci-fi in a top-ranked computer science conference at present. For that reason, we examine the CHI main track for the presence and nature of sci-fi referrals in relationship to HCI research. We search for six sci-fi terms in a dataset of 5812 CHI main proceedings and code the context of 175 sci-fi referrals in 83 papers indexed in the CHI main track. In our results, we categorize these papers into five contemporary HCI research themes wherein sci-fi and HCI interconnect: (1) Theoretical Design Research; (2) New Interactions; (3) Human-Body Modification or Extension; (4) Human-Robot Interaction and Artificial Intelligence; and (5) Visions of Computing and HCI. In conclusion, we discuss results and implications located in the promising arena of sci-fi and HCI research.

    Speaking Symbols: A semiotic analysis of the Smart Ping system in League of Legends2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis brings attention to communication systems in games and how their development has stagnated. The focus is directed towards visual communication and the question of “Can the Smart Ping system in League of Legends suggest visual communication as a viable solution for in-game communication in multiplayer games, according to the semiotic model of Roland Barthes? ” is presented. Roland Barthes’ two order of signification model is then used to perform an analysis of the visual communication system called Smart Ping in the game League of Legends. The findings suggests that visual systems can be a viable solution as they provide visual techniques in design, tactic use for players while being effective to execute, helps removing language barrier problems and can use cultural aspects to an advantage in design when creating the system, making it easier for players to understand the message created. In-game multiplayer communication, is a vital part of how a game succeeds or falters when providing tools for players to communicate; as it is one of the main areas that creates frustration for the players. An aspect of this importance is that as frustration builds up, the flaws of design are found and questioned, and if not answered, damages the community due to the consequences of not solving the issues within the game. Therefore it is important that designers do not neglect the issues related to the current systems, and instead work to find new solutions, because if they do not, it damages the relationship between consumers and developers. This topic is discussed as frustration for players also bring toxicity into the community of games. To finalize the thesis suggests an approach in connection to visual communication systems and emphasizes experimentation in game design as an important part of development; while as a developer staying open towards feedback helps, as it strengthens the community and can provide new solutions from unexpected sources.

    Effects on User Engagement as a Result of Improved Usability and Design in Form-Based User Interfaces2023Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis examines how usability and design improvements affect user engagement on a website. By conducting interviews and analysing user behaviour and feedback related to a job application form, the study demonstrates that enhancements in usability and design can lead to improved quality in user responses. Specifically, an increase in the length and quality of text field input was observed, along with improved responses regarding profile pictures, links, and documents. However, there are certain limitations to consider, including the fact that participants were aware of the monitoring during the interviews, which could influence the authenticity of the results. Additionally, other factors that could have influenced user engagement were not taken into account, making it difficult to solely attribute the changes to usability and design improvements.

    Conversation Analysis as a Design Research Method for Designing Socioculturally Contextual Conversational Agents2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This research paper presents a study exploring if using the Conversational Analysis (CA) method in design research could result in designing more socioculturally contextual conversational agents. The research specifically focused on understanding the 1) effect on the design outcome and 2) the role in the design process. This was studied through practice-based design research, participant evaluation of the design outcome, and expert interviews on the design method. The findings were analysed both qualitatively and quantitatively and showed, that socioculturally contextual design could potentially be a data-rich field of study with connections to design concepts such as inclusive design, affective design, design ethics, increased user experience, and further studies are therefore recommended. Furthermore, the study provided an understanding of the contexts in which the CA method may be useful in design, how it can potentially impact the design, and how to apply it to the design process and showed a positive effect on the design outcome in terms of socioculturally contextual design.

    Navigating through Frustrations: A User-Centered Approach to Enhancing Airborne Early Warning and Control System Operator Experience2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master thesis focuses on enhancing the user interface experience for Airborne Early Warning and Control (AEW&C) system operators in a military context. Collaborating with Saab, a defense sector company, the study employs the research through design and a user-centered design approach to investigate user needs and how they interact with the interface. The research reveals that despite the unique nature of the defense industry, operators respond poorly to a difficult-to-use interface, leading to frustration and underutilization of functionalities. The study identifies contextual factors such as information overload, user interface design and personalization, task difficulty and lack of help systems, stress, and cognitive load. Through the development and testing of a new interface prototype, incorporating design feedback sessions and iterations, the thesis addresses these contextual demands. The findings highlight the significance of introducing user experience in military environments, where complex system engineering and functionality have been traditionally preferred over simplicity and usability.

    Abstract [en]

    The students who are taught Greek as a second or foreigner language are in many cases expected to face two educational processes simultaneously. They have to learn the language as well as all the school subjects taught in this language: history, geography, religion, physics etc Compared to their schoolmates, who are functioning in the familiar environment of their mother language, these students should make double the effort and work twice as hard in order to keep pace with the rest of the class. A lot of different pedagogic approaches have been applied over the years in order to facilitate the learning of a second language in the elementary schools around the world. The experts in the field of education support that the teachers should find suitable motives in order to mobilise their students’ potentials so that their academic objectives are achieved. Based on the reality that the children today are surrounded by numerous high technology media and that the fashionable computer games can be particularly addictive, the teachers can borrow from the industry of entertainment and create pleasant and effective conditions of teaching. In the attractive environment of the "virtual class" and with the suitable "mind tool" accessible to the students, so much the learning of a second language as well as the learning of the subjects taught in this language can be promoted successfully. Moreover, the Greek school teachers that travel in many different countries in order to teach the Greek language to the children of immigrants, can surely benefit from such educational software and facilitate their mission by participating in the "school-twinning" networks of the world. After briefly reviewing the psychological theories of language learning and acquisition, we will discuss the possibilities and weaknesses of using certain technical systems in the classroom for the conquest of a second language. Our main hypothesis is that the learning and the usage of the Greek language presupposes real activities in a Greek linguistic environment and that the systems of technology and information have the possibility of creating such an environment that will strengthen the learning. The presentation will try to address the issues generated above.

    Social drone companion for the home environment: a user-centric exploration2017In: Proc. 5th International Conference on Human Agent Interaction, New York: ACM Press, 2017, p. 89-96Conference paper (Refereed)
    Abstract [en]

    Recent research has focused on how to facilitate interaction between humans and robots, giving rise to the field of human robot interaction. A related research area is human-drone interaction (HDI), investigating how interaction between humans and drones can be expanded in novel and meaningful ways. In this work, we explore the use of drones as companions in a home environment. We present three consecutive studies addressing user requirements and design space of companion drones. Following a user-centered approach, the three stages include online questionnaire, design workshops, and simulated virtual reality (VR) home environment. Our results show that participants preferred the idea of a drone companion at home, particularly for tasks such as fetching items and cleaning. The participants were also positive towards a drone companion that featured anthropomorphic features.

    User-centered Visualizations of Transcription Uncertainty in AI-generated Subtitles of News Broadcast2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    AI-generated subtitles have recently started to automate the process of subtitling with automatic speech recognition. However, people may not perceive that the transcription is based on probabilities and may entail errors. For news that is broadcast live may this be controversial and cause misinterpretation. A user-centered design approach was performed investigating three possible solutions towards visualizing transcription uncertainties in real-time presentation. Based on the user needs, one proposed solution was used in a qualitative comparison with AI- generated subtitles without visualizations. The results suggest that visualization of uncertainties support users’ interpretation of AI-generated subtitles and helps to identify possible errors. However, it does not improve the transcription intelligibility. The result also suggests that unnoticed transcription errors during news broadcast is perceived as critical and decrease trust towards the news. Uncertainty visualizations may increase trust and prevent the risk of misinterpretation with important information.

    Abstract [en]

    Background: Parkinson disease (PD) is a chronic degenerative disorder that causes progressive neurological deterioration with profound effects on the affected individual's quality of life. Therefore, there is an urgent need to improve patient empowerment and clinical decision support in PD care. Home-based disease monitoring is an emerging information technology with the potential to transform the care of patients with chronic illnesses. Its acceptance and role in PD care need to be elucidated both among patients and caregivers.

    Objective: Our main objective was to develop a novel home-based monitoring system (named EMPARK) with patient and clinician interface to improve patient empowerment and clinical care in PD.

    Methods: We used elements of design science research and user-centered design for requirement elicitation and subsequent information and communications technology (ICT) development. Functionalities of the interfaces were the subject of user-centric multistep evaluation complemented by semantic analysis of the recorded end-user reactions. The ICT structure of EMPARK was evaluated using the ICT for patient empowerment model.

    Results: Software and hardware system architecture for the collection and calculation of relevant parameters of disease management via home monitoring were established. Here, we describe the patient interface and the functional characteristics and evaluation of a novel clinician interface. In accordance with our previous findings with regard to the patient interface, our current results indicate an overall high utility and user acceptance of the clinician interface. Special characteristics of EMPARK in key areas of interest emerged from end-user evaluations, with clear potential for future system development and deployment in daily clinical practice. Evaluation through the principles of ICT for patient empowerment model, along with prior findings from patient interface evaluation, suggests that EMPARK has the potential to empower patients with PD.

    Conclusions: The EMPARK system is a novel home monitoring system for providing patients with PD and the care team with feedback on longitudinal disease activities. User-centric development and evaluation of the system indicated high user acceptance and usability. The EMPARK infrastructure would empower patients and could be used for future applications in daily care and research.
