    Robots, ethics and language2015Ingår i: Computers & Society: The Newsletter of the ACM Special Interest Group on Computers and Society Special Issue on 20 Years of ETHICOMP / [ed] Mark Coeckelbergh, Bernd Stahl, and Catherine Flick; Vaibhav Garg and Dee Weikle, ACM Digital Library, 2015, s. 268-273Konferensbidrag (Refereegranskat)
    Abstract [en]

    Following the classical philosophical definition of ethics and the psychological research on problem solving and decision making, the issue of ethics becomes concrete and opens up the way for the creation of IT systems that can support handling of moral problems. Also in a sense that is similar to the way humans handle their moral problems. The processes of communicating information and receiving instructions are linguistic by nature. Moreover, autonomous and heteronomous ethical thinking is expressed by way of language use. Indeed, the way we think ethically is not only linguistically mediated but linguistically construed – whether we think for example in terms of conviction and certainty (meaning heteronomy) or in terms of questioning and inquiry (meaning autonomy). A thorough analysis of the language that is used in these processes is therefore of vital importance for the development of the above mentioned tools and methods. Given that we have a clear definition based on philosophical theories and on research on human decision-making and linguistics, we can create and apply systems that can handle ethical issues. Such systems will help us to design robots and to prescribe their actions, to communicate and cooperate with them, to control the moral aspects of robots’ actions in real life applications, and to create embedded systems that allow continuous learning and adaptation.

    The importance of language in teaching and learning ethics2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    The use of English as the teaching language at University courses for non-native English-speaking students is spreading more and more. Certain learning problems and difficulties have been reported already. However, in ethics courses, language has a greater impact. Concepts like right, wrong, values, etc., are complex. The meaning of such concepts is culturally embedded and they are constantly created and re-created in contexts of communication. The notions of, and every-day life encounters with “right” and “wrong” are linguistically experienced, described, and mediated, and therefore much more dependent on language than for example technical terms. In teaching, cognitive coordination between teacher and students is necessary in order for learning to take place. This is a kind of negotiation between instruction and the cognitive needs of the students, which, in order to be successful, has to be mediated through a shared language regarding the meanings of ethical and value terms and concepts. Using a language that is foreign to the students or the teacher or both, creates a need to re-create these meanings in class. This is clearly a burden that should be considered.

    User-centred design and agile development of IT systems2006Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Despite the knowledge on the interaction between humans and computers, too many IT systems show great deficits when it comes to usability. Every day we run into technology that makes our every day life and our work unnecessarily complex and difficult because of the IT systems that are not designed to support our tasks in a usable way. This thesis deals with different aspects of usability and the process of how to develop usable IT systems effectively. Primarily, the systems concerned are used in professional work, such as case handling systems in large government organisations.

    The main objective of this research is to understand which essential factors in the system development process that facilitate the development of usable IT systems. Another key subject is how human-computer interaction (HCI) knowledge can be integrated into systems development, in particular the integration of user-centred design (UCD) and agile software development. The research is based on a qualitative approach and on reflections from my own experience in development projects. It also includes exploratory studies and design cases.

    The attempts of bridging the gap between HCI and software engineering have not been notably successful in practice. To address some of these problems, there is a need for a more precise definition of user-centred design, which is proposed in the thesis. Also, the complicated reality of systems development is not considered enough by HCI researchers and practitioner. To reach better results, UCD has to be integrated as a natural part of the development process. In the thesis, I argue that the agile approach together with UCD can be a good starting point for this integration. The agile approach emphasises that responding to change in development is more important than strictly adhering to a plan. Also, it prioritises regular deliveries of working software over extensive models and documentation. However, from an HCI perspective, agile processes do not inherently provide the required support for user-centred design. Nevertheless, the basic values and specific methods of agile development may have the potential to work very well together with UCD. For instance, iterative development is fundamental to both user-centred design and agile development.

    Finally, the research addresses how iterative methods can be used to find design solutions that support the users to cope with the problems of overview and control in case handling work.

    Cognitive work analysis in practice: Adaptation to project scope and industrial context2016Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The Cognitive Work Analysis (CWA) framework is widely used by researchers for the analysis of complex systems. It, however, lacks the same impact amongst industrial practitioners. This thesis investigates possible adaptations of the framework to project and industrial constraints, and the consequences associated with such adaptations. Long haul heavy vehicle transportation is the application domain for the work presented in the thesis. The CWA framework has been applied within the Methods for Designing Future Autonomous Systems (MODAS) project. Adaptations have been made to fit the framework within the project constraints and the industrial contexts. Interviews with stakeholders in an industrial organization regarding possible use of models from the CWA framework have been made. The CWA was scaled to available resources when applied within the MODAS project. From this we realized that prioritization of work activity can have consequences on the resulting systems ability to handle unforeseen events. Further, a focus on the current system probed a rapid out-dating of the analysis due to technical development. The conclusion is that even if advantages are lost during adaptation due to practical constraints, the CWA framework could add value to practitioners within industry if adapted to the industrial context.

    Abstract [en]

    Introducing automation in a human-machine system changes the tasks performed by human operators. It is difficult to analyse systems for which there are no experienced operators. This issue emerged within a project with the aim to develop a human–machine interface for a highly automated long-haul vehicle. To handle the problem, a formative strategies analysis method with promises to enable desktop analyses through predefined strategy categories was adopted. The method was used to investigate strategies for controlling the future long haul vehicle by conducting workshops with today's drivers. The method was shown to be a valuable asset in eliciting strategies for revolutionary design.

    Abstract [en]

    As part of a broader industrial project, the first two stages of a Cognitive Work Analysis (CWA, Work Domain Analysis [WDA] and Control Task Analysis [ConTA]) were completed for Long Haul Commercial Road Transport. To support the potential uptake of CWA by different stakeholders within the industrial organization, parts of the ConTA Contextual Activity Template (CAT) were truncated. The goal of the current, exploratory study, was to identify which stakeholders within the industrial organization could benefit from using the WDA or CAT for either their Strategic (Research) or Product (Development) planning, and over what time horizon. We observed differences in the perceived usefulness of the WDA and the CAT between the different stakeholders. Innovative solutions to the issues raised should significantly enhance the industrial use of Cognitive Work Analysis.

    Work domain analysis of an intensive care unit: An Abstraction Hierarchy based on a bed-side approach2016Ingår i: Proc. Human Factors and Ergonomics Society Europe Chapter 2015 Annual Conference, 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    Work in intensive care units requires interaction with several medical devices and interpretation of dynamic information from several sources. The aim of the current study was to gain understanding of the work domain to support the development of a holistic information environment and further analyses of risky situations. A total of 18 hours of bed-side observations at an intensive care unit and interviews with three experienced intensive care unit nurses were conducted in order to receive input data for the modelling of the work domain. The domain was modelled in an abstraction hierarchy, as according to the first phase of the cognitive work analysis framework. The results show that the ultimate purpose of the work carried out in an intensive care unit is keeping patients alive while gaining time for treatment, but also to perform treatment and relieve symptoms. The purpose is represented at the top level of the model, and lower levels include functions as supporting the patients’ vital functions and avoiding secondary complications. With this work domain analysis as a basis, three different design challenges identified can be dealt with systematically.

    Emotions at play: gaining emotional knowledge using a video game2014Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Det finns en spridd uppfattning att videospel kan fungera som lärandespel för barn. Generelltsätt har denna uppfattning stöd i skolan och det finns därför även en önskan att producera spel som kan användas till att undervisa traditionella kärnämnen, exempelvis matematik eller biologi.  Dessa ämnen är betydelsefulla att bemästra, dock finns även andra mer mjuka aspekter som kan ha en avgörande betydelse för barnets lärande. En sådan aspekt gäller den viktiga betydelse som känslor har i ett socialt sammanhang. I denna uppsats undersöker jag hur barn uppfattar och använder känslor då barnen spelar ett spel som är designat enkom för detta syfte. Spelet utnyttjar en design som låter spelaren interagera med tecknade djur i skilda scenarion. Jag redovisar resultat som baseras på ett urval av trettiotre (33) förskolebarn och sex (6) föräldrar. De material som samlades in bygger på en kvalitativ datainsamlingsmetod som är uppbyggd i två steg. I steg ett samlades data in genom observationer samt uppföljande intervjuer. I steg två genomfördes sedan observationer följt av demonstrationer då barnen använde gosedjur. Jag visar, genom att applicera ett ekologiskt ramverk samt teori kring emotionell intelligens, att barnen kan uppfatta känslor som manifesteras i ett videospel. Jag visar också att spe- let kan spelas genom en slumpmässig interaktion där barnen inte behöver använda känslor för att föra spelet framåt, och jag konkluderar därför att det är möjligt att barnen inte lär sig känslor som en följd av själva spelandet.

    Usability and users’ health issues in systems development2003Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The figures of reported health problems in computer-supported, administrative, work are alarmingly high and increasing. The main health problems are visual discomfort, repetitive strain injuries (RSI) and stress-related disorders. Some important risk factors are poor workstation design, constrained work postures, repetitive work and long hours of computer use every day. Others are high demands, poor control over workload and work pace and poor relations to management and colleagues. There is also evidence that poor design and usability of the computer systems as well as technical problems with the computer add to the pressure perceived by the user, which may in its turn cause stress-related disorders.

    Systems (software) development is often technology-driven and the design and contents of the resulting system shapes the work situation, including factors affecting the users' health and well-being. There are numerous examples in the literature describing how poorly designed systems fail to support the real work practices, introducing new ones that are inadequate and more time-consuming. Thus these, supposedly supporting, computer systems get in the way of efficient and effective work, adding a burden on the workers rather than helping them out.

    This thesis tries to describe some of the relations between the systems development process and users' health complaints, in a work context. I also discuss whether or not the concepts of usability and user experience can be used to address users' health issues in the systems development process. The main results indicate that although usability must be addressed, it is not sufficient. Occupational health issues must be explicitly integrated in systems development, and be given priority. This thesis also describes some potential methods and techniques for doing that.

    Utvärdering av innovationsstöd inom eHälsa i Stockholms läns sjukvårdsområde2015Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This thesis investigates how actors within the health care sector work with innovation and development of information technology products, also called eHealth. eHealth services is an expanding area which will play a vital role in tomorrow's health care system. Staffs within health care organizations do have a lot of ideas of how to develop and improve the work process and how to provide better health care.

    The study was performed at Stockholms läns sjukvårdsområde (SLSO) and the purpose of this project is to evaluate the support given by SLSO innovation gateway. Innovation gateway is an approach that has been spread to some of Sweden's county councils, where the aim is to take advantage of the staffs ideas and to develop products and services based on activities that contribute to improving health care. Interviews and observations have been made to understand the innovation environment in Stockholms läns lansting. This gave an understanding for which user-centred aspects that are important to consider when developing eHealth innovations. Aspects like security, usability and availability are essential to consider when creating innovations that create value for patients and employees. The results also showed that staffs need better support from the organization and an understanding and knowledge in information technology, law and project management to be able to manage and develop eHealth innovations. The study has also shown that the client, the project and developers must all be involved in the innovation process and work with the organization to succeed. It requires a reallocation of resources to enable SLSO to provide the demanded support.

    Design and usability in telemedicine2001Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    A design of computer systems, that effectively supports the user, is a major goal within human-computer interaction. To achieve this, we must understand and master several tasks. These tasks concern firstly what to develop and secondly how to develop the system.

    The design and implementation of effective and efficient user interfaces is a prerequisite for the successful introduction of computer support in the medical domain. We base our work on a fundamental understanding of cognitive aspects of human-computer interaction, as well as on detailed analysis of the specific needs and requirements of the end users, i.e., the medical professionals.

    This thesis presents several approaches for development of systems for computer-supported work in health care. The solutions described concern vital problem areas: (1) the focus on the work tasks to be performed, (2) the cost of software and the way competition works in a networked world. Solutions to these problems can lead to more usable systems from a user's perspective but may also change the nature of computer applications.

Big investments in information technology have been made to ensure efficiency and quality within organisations in health care. This has led to high requirements in documentation and resulted in an increase in administration which gradually more often is done by nurses and doctors. A major problem is that it is difficult to gain access to the information recorded in all the different systems, which is their objective. This causes double documentation instead of being a support in follow-up performance.  

    This study investigates the use of a central warehouse to enhance how people work with statistics at a clinic. The purpose of the project was to identify need and issues surrounding the clinical internal statistic of the Department of Neurosurgery and then give an improvement proposal in the form of a prototype software tool. During the project a requirement analysis in the form of interviews and observations in the clinic was carried out and the project team could identify users, systems, artefacts and information needs were identified.

    The result of this work is a prototype which was developed in a user-centered process, where contact with the IT-department (e-Hälsa) provided opportunities for access to data. The project has contributed a survey of the clinic where information- and functional needs about administrative statistics have been compiled and are the basis for a prototype that demonstrates a possible concept for recording and monitoring.

    How do people evaluate virtual goods in social media? The case of Dota 22019Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Virtual purchases are the main source of revenue for developers of F2P games being a market with expected 17.4 billions of dollars volume in 2019. Despite the broad scope of research of virtual purchases, it is still unclear how the player evaluate non-functional goods. Based on analysis of discussions of virtual decorative items this work what experiences nonfunctional items grants players with and how those experiences discussions reflect in the item’s price. 

    With the use of Structural Topic Modeling framework this work demonstrates the dimensions of players’ experience in their association with price change on the case of Reddit.com subreddit /r/Dota2. Analysis reveals three main categories of discussions: dimensions of hedonic value, dimensions of social value, expectations mismatch. This work contributes to studies of virtual purchases by decomposing each category into experience dimensions and by revealing the relationship between extracted experience dimensions and items price.

    Software engineering with conflicting user needs: Patient accessible electronic patient records2018Ingår i: Proceedings of the International Workshop on Software Engineering in Healthcare Systems, IEEE, 2018, s. 1-1Konferensbidrag (Refereegranskat)
    Abstract [en]

    With roots in Human Centred Software Engineering, and in User Centred Systems Design Asa Cajander has lead research on Patient Accessible Electronic Health Records (PAEHR) for six years. This experience has made her revisit the core values of user centeredness, as the different user groups of PAEHR indeed describe conflicting user needs. In this key note she will present the patients' perspective of the system, and contrast that with the perspectives of physicians and nurses. The conflicting needs of the different user groups will be illustrated by a small role play, and she will relate and discuss the findings in relation to the design and development of eHealth systems.

    Usability – Who Cares?: The Introduction of User-Centred Systems Design in Organisations2010Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis analyses the difficulties encountered in the promotion of usability, especially in relation to occupation health issues, when developing IT systems in a public authority. It examines what happens when User-Centred Systems Design (UCSD) approaches are introduced to organisations with in-house systems development for their employees. It studies how stakeholder values affect the outcomes in terms of usability, occupational health, and institutional acceptance. Moreover, new methods are examined and evaluated as potential tools for assisting the adoption of UCSD. These methods are for example Field studies for system developers, Usability coaching for stakeholders and Management views of usability.

    A stated aim is to influence systems development in practice. Hence an action research paradigm has been employed, carrying out research and change in real life settings, gathering and analysing data using qualitative techniques.

    This thesis is based on a constructivist perspective, where theories in the areas of learning and organisational change have been used in order to better understand the research questions.

    The research demonstrates that most people are enthusiastic to, and interested in, UCSD with a focus on the computerised work environment. Many of the stakeholder groups, such as managers, users, project managers and system developers, changed their construct of identity as well as practice when UCSD was introduced.

    However, this research shows that there are several values that affect systems development and hinder usability work. These include for example value of rationality and objectivity, and differing values and perspectives underpinning descriptions and discourse on work and systems development. Values such as automation, efficiency, and customer satisfaction shape the development of new technology, and ultimately the tasks, work practices integrated in IT systems.

    Moreover, the results demonstrate that even though many consider usability as important, few take active responsibility for it, as the title of this thesis suggests.

    Abstract [en]

    Work environment and occupational health problems of different nature are constantly increasing in computer supported work. Most efforts to improve the work environment are focused primarily on physical aspects, and to some extent on psychosocial aspects. Mental workload and cognitive problems are of a more complex nature, more difficult to measure and provide efficient solutions to, and are more seldom studied or solved. Solutions to work environment problems are usually applied to already existing work situations through improved equipment and work place design, health programmes, education, reorganizations, etc. The problems are seldom prevented by means of applying relevant methods early in the systems development process, before the artefacts have been designed and implemented. This paper, and the following papers of this special issue, will focus on the need to integrate different interdisciplinary methods at different phases in the development process of computerized support systems, with the ultimate goal to prevent work environment problems and decrease the health risks to the users.

    Abstract [en]

    In trying to understand the problem of poor usability in

    computer-supported work, this article looks at management

    and their perspective on usability in a public authority.

    What are their underlying basic values, assumptions and

    attitudes? Why do managers interpret usability as they do,

    and what are the consequences for the organization and for

    usability? The empirical basis is an interpretive case study

    where 19 semi-structured interviews were conducted.

    Results indicate that usability is interpreted differently,

    depending on the formal roles of informants. Furthermore, a

    majority of the informants express personal, but limited,

    responsibility for usability. Moreover, we found that basic

    values are based on an instrumental view of work where

    efficiency and economy are important constituents. We

    identified that even though users participate in IT

    development, they have no formal responsibility or

    authority. They have become IT workers in that they

    perform highly technical tasks such as integral testing.

    Values and perspectives affecting IT systems development and usability work2006Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Computer supported work is often stressful and inadequate computer systems and poor usability contribute to the problem. Still the work situation, and work environment of users are seldom considered when developing computer systems, and it is difficult to incorporate the ideas of User Centred Systems Design (UCSD) in practice. Hence, this research addresses the difficulty in integrating usability, UCSD and occupational health issues in IT systems development in order to improve the resulting work situation and well-being of users. How do basic values and perspectives of stakeholders in systems development projects affect the work with UCSD, usability and users’ health issues in the organisations studied?

    This research aims at influencing systems development in practice; hence, research is carried out in real life settings with an action research approach. Data is gathered and analysed with a qualitative research approach with interview studies, meetings with stakeholders, analysis of documentation, observations and field studies. The theoretical framework adheres to situated action, participatory design, and UCSD that stresses the importance of involving users in the design process.

    This research shows that several basic values and perspectives affect systems development and hinder the usability work, for example, the perspective on user representatives, the value of rationality and objectivity, and the perspective underpinning descriptions and discourse on work. Moreover, this research indicates that the strong business values of automation, efficiency and customer satisfaction shape the development of new technology, and ultimately the tasks and work practices of the civil servants. In short, the studies show that there are some contradictions in business values and the implementation of user-centred systems design, usability and health issues in systems development.

    Attitudes and perspectives are not easily changed, and change comes gradually. In these organisations, we continuously discuss the integration of health issues in systems development, and by introducing and changing the models of systems development these will hopefully enable communication and change forwards of new perspectives and values. However, a focus on models alone is insufficient and therefore we need to develop a systematic approach to include reflection and new perspectives. Perhaps the reflection itself would help us see our values and perspectives and to alter them?

    Contextual personas as a method for understanding digital work environments2015Ingår i: Human Work Interaction Design: Work Analysis and Interaction Design Methods for Pervasive and Smart Workplaces, Springer, 2015, s. 141-152Konferensbidrag (Refereegranskat)
    Abstract [en]

    The role of IT at the workplace has changed dramatically from being a tool within the work environment to include all aspects of social and private life. New workplaces emerge where IT becomes more and more divergent, embedded and pervasive. These new aspects of IT at work need to be addressed with new or adapted human centred activities. This paper present and discuss a modified version of personas called contextual personas developed to better address the new working life. The contextual personas were developed using contextual inquiry, and focus groups as well as argumentative design. From the process of developing the contextual personas we learned that they are indeed a promising tool to understand the new work situations, and especially the holistic view of IT at work as they bring the whole working-life of the personas into focus. Finally, we discuss in what way the contextual personas could give developers extended understanding of the users' future office work environment.

    Detecting perceived quality of interaction with a robot using contextual features2017Ingår i: Autonomous Robots, ISSN 0929-5593, E-ISSN 1573-7527, Vol. 41, nr 5, s. 1245-1261Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This work aims to advance the state of the art in exploring the role of task, social context and their interdependencies in the automatic prediction of affective and social dimensions in human-robot interaction. We explored several SVMs-based models with different features extracted from a set of context logs collected in a human-robot interaction experiment where children play a chess game with a social robot. The features include information about the game and the social context at the interaction level (overall features) and at the game turn level (turn-based features). While overall features capture game and social context at the interaction level, turn-based features attempt to encode the dependencies of game and social context at each turn of the game. Results showed that game and social context-based features can be successfully used to predict dimensions of quality of interaction with the robot. In particular, overall features proved to perform equally or better than turn-based features, and game context-based features more effective than social context-based features. Our results show that the interplay between game and social context-based features, combined with features encoding their dependencies, lead to higher recognition performances for a subset of dimensions.

    Exploring design and product development data in high-tech companies using data visualization2013Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In high-tech companies, user experience has become an important part of data-driven product development, but unfortunately the artifacts created by user experience work are often stored in disparate documents and databases, and it is difficult to get a big picture of all the artifacts that have been created and how they relate to each other and to other product development data. Data visualization is one way to approach solving these issues, but how can this data be presented to users in a meaningful way such that both the artifacts and the relationships between them are understood? Three hierarchical data visualizations - partition, sunburst, and zoomable treemap - were built around some early product development data. These visualizations were tested in a comparative exploratory usability test with six users to find how well users understood the data and the relationships between the data. The most significant results were that most users did not know how to interact with the partition and sunburst visualizations until prompted to do so, users had a difference in understanding the data between the sunburst and partition visualization, and some techniques worked very well to keep users oriented while others did not. Future work should first focus on adding a creative element to the tool, where data can be added and relationships can be built in the visualization itself, and then focus on testing the tool again with a more specific audience of strategic planners, UX designers, and requirements engineers.

    Engagement perception and generation for social robots and virtual agents2016Ingår i: Toward Robotic Socially Believable Behaving Systems: Volume I, Modeling Emotions, Springer, 2016, s. 29-51Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Technology is the future, woven into every aspect of our lives, but how are we to interact with all this technology and what happens when problems arise? Artificial agents, such as virtual characters and social robots could offer a realistic solution to help facilitate interactions between humans and machines—if only these agents were better equipped and more informed to hold up their end of an interaction. People and machines can interact to do things together, but in order to get the most out of every interaction, the agent must to be able to make reasonable judgements regarding your intent and goals for the interaction.We explore the concept of engagement from the different perspectives of the human and the agent. More specifically, we study how the agent perceives the engagement state of the other interactant, and how it generates its own representation of engaging behaviour. In this chapter, we discuss the different stages and components of engagement that have been suggested in the literature from the applied perspective of a case study of engagement for social robotics, as well as in the context of another study that was focused on gaze-related engagement with virtual characters.

    Designing 'True Colors': A Social Wearable that Affords Vulnerability2019Ingår i: CHI 2019: Proceedings of the 2019 CHI Conference on Human Factors in Computing Systems, Association for Computing Machinery (ACM), 2019, artikel-id 33Konferensbidrag (Refereegranskat)
    Abstract [en]

    Vulnerability is a common experience in everyday life and is frequently perceived as a flaw to be excised in technology design. Yet, research indicates it is an essential aspect of wholehearted living among others. In this paper, we present the design and deployment of 'True Colors', a novel wearable device intended to support social interaction in a live action roleplay game (LARP) setting. We describe the Research-through Design process that helped us to discover and articulate the possibility space of vulnerability in the design of social wearables, as support for producing a sense of social empowerment and connection among wearers within the LARP. We draw conclusions that may be of value to others designing wearables and related technologies aimed at supporting co-located social interaction in games/play.

    Att hitta användbarhetsproblem med Google Analytics - är det möjligt?2016Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The scope of research is usability problems and web analytics. This thesis examines

    whether or nor Google Analytics can point out the usability problems a website has,

    and describes the process of usability analysis of the two websites belonging to the

    organisation ArtDatabanken. The research is divided into two parts. The first part

    describes the collection of the usability problems ArtDatabanken had and what

    usability problems that were identified. The second part describes the

    Google Analytics analysis of the usability problems that were possible to investigate,

    how the study was designed and the result from that investigation. Finally, some

    recommendations are given on how Google Analytics should be improved to more

    effectively find potential usability problems. The results of the research show that

    Google Analytics can find some of the identified usability problems, but the automatic

    implementation and its standard reports is not effective enough. By tracking all of the

    events at the site, a better understanding of what users are doing during their visits

    could be obtained. This together with some changes of the built-in reports would

    increase the possibilities to find potential usability problems by using Google

    Analytics.

    Using rapid prototyping to explore design implications for a pill-dispensing social agent2017Ingår i: Proc. 5th International Conference on Human Agent Interaction, New York: ACM Press, 2017, s. 53-59Konferensbidrag (Refereegranskat)
    Abstract [en]

    The process of managing one's daily intake of medication has been shown to be error-prone for a variety of reasons. In this paper, we explore, through a rapid prototyping approach, the design implications for a social robotic agent intended for dispensing medicine. The process started with initial interviews with medical experts to allow for a better understanding of the design space. Their input helped us realise a low-fidelity, animal-like, robotic prototype for pill-dispensing. We report initial impressions of the prototype from four pharmacists. Based on those findings, we present design implications categorised into: look and feel, social role, desired task, and the agent's presence in a home environment.

    Artificial Intelligence in Games: Faking Human Behavior2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Denna rapport undersöker möjligheterna att förfalska mänskligt beteende genom artificiell intelligens i datorspel, med hjälp av effektiva metoder som sparar värdefull utvecklingstid och som även skapar en rikare upplevelse för spelare. Den specifika implementationen av artificiell intelligens som utvecklas och diskuteras är ett neuralt nätverk som kontrollerar en finite-state machine. Målet var att efterlikna mänskligt beteende snarare än att simulera verklig intelligens. Ett 2D shooter-spel utvecklas och används för utförda experiment med mänskliga och artificiell intelligens-kontrollerade spelare. De sessioner som spelades under experimenten spelades in, för att sedan låta andra människor titta på inspelningarna. Både spelare och åskådare av spelsessionerna lämnade återkoppling och rapporter för senare analysering. Datan som samlats in från experimenten analyserades, och reflektioner utfördes på hela projektet. Tips och idéer presenteras till utvecklare av shooter-spel som är intresserade av en mer människolik artificiell intelligens. Slutsatser läggs fram och extra information presenteras för att kunna fortsätta iterera vidare på denna undersökning.

    Modern Virtual Reality. And the effects of affecting human senses to increase immersion2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Modern virtual reality is an ever growing subject in today’s society. I delved deeper into some key moments in the development of modern virtual reality. Oculus Rift has shown incredible potential. Some developments even seek to envelope the human senses in virtual reality as well.   With several different approaches to the same solution there are many ways that the experience can affect the overall immersion of a consumer into the product.

     The tests I performed were primarily focused around the interaction between the human senses and immersion. The immersion can be increased or decreased by basic means of stimulating the human senses. This test was implemented by having volunteers participate in two phases in a supervised environment. In the first phase, the participants were subjected to an increase in immersion by stimulating senses other than their eyes and ears. The second phase involved reducing the participants’ sensory stimulation to see what the difference in immersion would be between the two phases.

     The results of the investigation show that manipulating the human senses does have an impact on immersion when using virtual reality. Immersion can be affected by increasing or decreasing the stimuli for the human senses.

    Prediktiv analys i människans tjänst2019Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Predictive Analysis is a process for extracting information from large amounts of data and using it to make qualified predictions about future results. While previously the lack of available data has been a challenge within the field, big questions today are instead how to use the results, and the way in which these are presented in order for the user to be able to take advantage of the information.

    The purpose of this thesis has been to create hypotheses for how predictive analysis can be used in practical decision-making contexts, whereby the decision- maker is under time pressure, especially with regard to how the result can be visualized. This has been done through a case study at the Uppsala Ambulance Monitoring Center. The method used for the study is called Contextual Design, which has helped create an understanding of the users and the system they work in. Using this understanding, a prototype has been created, which has been tested on the users to see how well they have been able to interpret the information that has been visualized.

    Predictive analysis has proved to be helpful primarily in less urgent cases and to help the decision maker to differentiate matters similar to each other. For visualization of the predictive results, it has been found that these is better shown as a comparison between the user's decision hypothesis and historical decision results rather than only as an absolute value. Furthermore, it has been found that a high degree of transparency in the information on which the results are based is preferable, but that it is important that clear explanations are given for the results shown.

    Abstract [en]

    This thesis investigates the public transport system in the city of Uppsala in Sweden. This thesis bases itself on the fact that the development of a new ticketing and payment system is about to start. The purpose of the thesis is to help increase the number of journeys travelled with public transport. To achieve this, the goal of the thesis is to present a vision for UL’s new payment and ticketing system with concepts of interaction design in mind whilst investigating whether a simplified system might increase travel with public transport.

    The thesis uses surveys, interviews and usability testing of the present-day system. The opinions can be summarised such that people in general find difficulties in grasping the different fare zones of the public transport system and do therefore experience difficulties in buying the correct ticket for their specific journey. 

    The new ticketing system should consist of a redesigned fare structure, where a complete removal of the fare zones would create perhaps the most intuitive ticketing system. The new ticketing system should also be able to handle contactless payments, easing the burden on bus drivers who will not need to issue tickets to passengers. In general, a downscaling of the current ticketing system is preferable to avoid confusing travellers. It is of the essence to consider the ticketing and payment system as a sociotechnical system since investigating neither technology nor people alone will lead to a successfully implemented system. They need to be investigated jointly.
