    How expressiveness of a robotic tutor is perceived by children in a learning environment2016Ingår i: Proc. 11th ACM/IEEE International Conference on Human Robot Interaction, Piscataway, NJ: IEEE Press, 2016, s. 423-424Konferensbidrag (Refereegranskat)
    Abstract [en]

    We present a study investigating the expressiveness of two different types of robots in a tutoring task. The robots used were i) the EMYS robot, with facial expression capabilities, and ii) the NAO robot, without facial expressions but able to perform expressive gestures. Preliminary results show that the NAO robot was perceived to be more friendly, pleasant and empathic than the EMYS robot as a tutor in a learning 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.

    Making sense of usability: Organizational change and sensemaking when introducing user-centred systems design in public authorities2009Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Computers have become an everyday encounter, not at least in work settings. These computers must support the user in order for her to work in an effective and efficient manner. The field of Human-Computer Interaction (HCI) has among other things been focusing on this issue, and there are numerous methods and activities that aim at helping developers to develop usable computer systems. However, the methods and activities must be used in practice in order to be beneficial, not only within research, thus the methods must make sense to the system developers, as well as the organization in which they shall be applied. Furthermore, the organization must change in order to incorporate these methods and activities, and this change must impact a larger part of the organization than just the IT-department.

    My research has revolved around the introduction of usability methods in public authorities, in particular user-centred systems design (UCSD). My methodology has been action research, which implies a close collaboration with practitioners. Some of the methods used to gather data have been interviews, participatory observations, research diaries and field studies.

    In this licentiate thesis I present my work up to date and the theories that have informed my understanding of organizations and organizational change. Furthermore I have been influenced by the sensemaking theory, which can be used in order to understand how people make sense of technology, methods and organizational change. With the help of these theories, I extend my results further than presented in the papers.

    The notion of organizational change when introducing usability issues has not achieved sufficient attention in the HCI-field. This thesis is a step towards an understanding of this issue. Furthermore, I have, with the results from my papers together with the theories presented shown that although formal documents can be used to promote change, it is not enough. Rather there is a need to further explore the interplay between formal aspects and the situated work, and how to enhance sensegiving in this sensemaking process.

    Usability in Transportation: Improving the analysis of cognitive work tasks2006Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In most vehicle domains within the transportation sector, traffic is increasing and vehicles are becoming more technologically advanced. In addition to this, drivers are faced with conflicting goals, such as punctuality, maintaining safety, minimizing fuel consumption, ensuring passenger comfort, etc. When accidents occur, the drivers' actions and mishaps are often in focus, even though the work environment, the organization behind the drivers, and the educational level may provide equally important explanations for incidents and actions.

    In this thesis, factors influencing operators' behaviour are acknowledged and attempts are made to understand how these factors affect vehicle operators in their daily work. Even though modern vehicles are equipped with new technology that supposedly aids drivers, studies of actual work typically reveal that these tools are not necessarily suited for their purpose.

    In a larger perspective, it is necessary not only to improve this technology, but to redesign how vehicle drivers perform their work. In practice, also traditional processes for development of technology affect how the operators work, although then simply a side effect of technology being introduced. Based on a deep understanding of the operators' work, the long-term goal here is to instead design new ways of working that allows the operators to use their skills to do meaningful driving tasks supported by technology.

    To acquire this understanding of how the operators work, a new method of information acquisition has been developed and tested within the rail and marine domains. These studies resulted with an understanding of what train and high-speed ferry operators are occupied with during their journeys, as well as insights into why they perform in certain manners and how they think and reason about these tasks.

    What's in your mind?: Collegial Verbalisation – An ecological approach to knowledge elicitation2014Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Knowledge elicitation of the work of professional operators, using traditional methods such as concurrent or retrospective verbalization is problematic. Concurrent verbalization distracts the operators from their primary task, and the operators have difficulties in verbalizing about their automated work tasks. Retrospective verbalization on the other hand, suffers from rationalization problems. An operator might give a perfectly good explanation of some action taken and might also be completely confident about truth of the verbalized information, when it in fact is incorrect. To overcome some of these problems, this thesis presents a new complementary verbalization method called Collegial Verbalization (CV).

    The CV-method utilizes the shared knowledge among work colleagues to improve the quality of the resulting information. The method consists roughly of the following steps; (1) Video tape subjects while they are working. (2) Play back interesting events to the subject’s colleagues individually and let them verbalize on the subject’s actions. (3) Compare the colleagues’ verbal reports to each other to find similarities, differences, etc. Throughout my research I have formulated, defined and assessed the new method in detail. The method has been applied to study train drivers, high-speed ferry operators, train traffic dispatchers and the medical staff at intensive care units.

    Comparative studies have shown; (1) that CV-protocols can be used as an independent source of data, (2) that colleagues produce reports with similar characteristics of retrospective verbal reports, (3) that the CV-method can produce more information than retrospective verbalization, because of the advantage of using multiple narrators. When the intention is to gather data as input to design, rather than establishing the original thought processes form the time of the studied events, the CV-method can also produce more reliable information than retrospective verbalization, because of the advantage of using multiple narrators.

    Based on these results, I have concluded that the CV-method has a clear advantage as a complementary information acquisition method, when studying the work of professional operators. The thesis ends with a discussion about several additional possible applications for the CV-method, such as applied team learning or psychological research in the field of decision making.

    Abstract [en]

    Two studies of train driving are presented, both within the framework of cognitive work analysis. In the first study, the modelling tool abstraction–decomposition space is adapted to routine conditions, making the analysis more representative for normal procedures. A major contribution to these analyses was the use of the method for ‘collegial verbalisation’. One particular advantage with this method over other verbalisation methods is that it supplies the analysts with data that contain much more information, but not at the expense of being more subjective. On the contrary, this method produces think-aloud protocols from video-recordings that do not have to be interpreted by the researcher. From these analyses, it was possible to distinguish information that is an intrinsic part of the train driver task from information that is dependent on the configuration and design of the current support system. The analyses show that the driver works in three rather separate time intervals with a long-range, a short-term and an immediate sense of perspective. The driver switches between these while travelling between two stations. Based on these behaviour-shaping constraints, a prototype of a planning area of a driver interface was developed, making feed-forward planning possible for the driver. Four design iterations were completed, using a user-centred system design (UCSD) approach. Early tests show that the planning area of the interface supports the feed-forward decision strategy used by drivers who prefer an active driving style. However, the driver group also made substantial changes in the design, indicating that UCSD is an efficient tool in order to capture user competencies, and to bridge the gap between analysis and design.

    Abstract [en]

    One way to investigate and account for the role of experience in dynamic decision-making tasks is to use a knowledge elicitation method, for example verbal protocols. Recently, methods for verbalisation by other subjects have been suggested as a way to elicit more information on thinking. One of these methods is here investigated in a quasi-experimental study on highly experienced and skilled train dispatchers. Collegial verbalisation is based on the procedure of videotaping practitioners while they perform their normal work tasks in their normal work setting. This is followed up by having a close colleague of the practitioner watch the video recordings and verbalise. The general hypothesis that verbal reports based on collegial verbalisations can provide protocol data that are close to the structure and content of verbal reports based on retrospective verbalisations was investigated. From this systematic comparison it is concluded that collegial verbalisations produce verbal protocols that are close to the retrospective verbal protocols on protocol and topic levels, but not on statement level. From this study, we conclude that the collegial protocols can be used as an independent source of data. It seems possible for a colleague to report verbally on a practitioners' observable behaviour in the same way as when the practitioner is doing a retrospective verbalisation and it may also be possible for a colleague to explain some of the non-observable behaviour of the practitioner.

    Verbal reports and domain-specific knowledge: a comparison between collegial and retrospective verbalisation2013Ingår i: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 15, nr 3, s. 239-254Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    One way to investigate and account for the role of experience in dynamic decision-making tasks is to use a knowledge elicitation method, for example verbal protocols. Recently, methods for verbalisation by other subjects have been suggested as a way to elicit more information on thinking. One of these methods is here investigated in a quasi-experimental study on highly experienced and skilled train dispatchers. Collegial verbalisation is based on the procedure of videotaping practitioners while they perform their normal work tasks in their normal work setting. This is followed up by having a close colleague of the practitioner watch the video recordings and verbalise. The general hypothesis that verbal reports based on collegial verbalisations can provide protocol data that are close to the structure and content of verbal reports based on retrospective verbalisations was investigated. From this systematic comparison it is concluded that collegial verbalisations produce verbal protocols that are close to the retrospective verbal protocols on protocol and topic levels, but not on statement level. From this study, we conclude that the collegial protocols can be used as an independent source of data. It seems possible for a colleague to report verbally on a practitioners' observable behaviour in the same way as when the practitioner is doing a retrospective verbalisation and it may also be possible for a colleague to explain some of the non-observable behaviour of the practitioner.

    Problematizing Sustainable ICT2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    How should we understand the relationship between information and communication technology (ICT) and sustainability? Generally, it is assumed that while ICT products contribute to many environmental and social problems as they are produced and disposed of, the potential of using ICT to achieve a more sustainable society is immense. However, despite the fact that such a discourse is favored not only in the industrial but also in the political and academic spheres, we have yet to see this presumed sustainability-related potential of ICT fully exploited.

    This thesis argues that conventional assumptions and understandings related to three abstractions in sustainable ICT research and practice – namely the technological, the social, and the sustainable – contribute to an overly optimistic discourse of sustainable ICT, which favors certain research approaches and practical applications. Adhering to such a discourse risks reinforcing, rather than breaking loose from, an unsustainable status quo. Through problematization, this thesis aims to unveil and challenge such underlying assumptions and understandings, based on insights from the social sciences and philosophy. New assumptions and understandings of sustainable ICT research and practice are suggested, and contribute with a perspective that among other things emphasize the ontological inseparability of the technological and the social, implying an anti-essentialist position embracing the value-ladenness and value and meaning mediatory aspects of such phenomena. The normative contributions include theoretical and methodological approaches to sustainable ICT design and sustainable ICT entrepreneurship – identified as two central practices for sustainable ICT to promote sustainability – that aim to mobilize politically charged discourses of our being together with each other, technologies and nature in order to facilitate collaborative action towards sustainable futures. This thesis should be seen as a critical contribution to fields interested in sustainable ICT, such as ICT for Sustainability (ICT4S) and Sustainable Human-Computer Interaction (SHCI).

    Abstract [en]

    Purpose– The purpose of this paper is to discuss the role of information and communication technology (ICT) for promoting environmental sustainability in a changing society. Isolated studies exist, but few take a holistic view. Derived from a Marxian tradition, the authors propose Ecological World Systems Theory (WST) as a holistic framework to assess the environmental impact of ICT. The theory is adapted responding to theoretical critiques of absence of change, namely state-centrism and structuralism.Design/methodology/approach– Theoretical study. Empirical examples derived from already published literature.Findings– Ecological WST focuses on the unequal distribution of environmental degradation, sees technological development as a zero-sum game rather than cornucopia and holds that technology is often seen as a fetish in today ' s society. The findings are that popular discourses on ICT and sustainability are since the 1990s becoming increasingly cornucopian, while conditions in the ICT value chain are less cornucopian.Research limitations/implications– Theoretical contributions to Marxian critiques of ICT, with more environmental focus than earlier Marxian critiques, for example Fuchs’ work. Develop a theoretical framework for ICT and sustainability which could be compared with works of e.g. Hilty, Patrignani and Whitehouse. The work is mostly based on existing empirical studies, which is a limitation.Practical implications– This theoretical framework implies that unequal environmental degradation in different parts of the world should be taken into account when assessing environmental impact, for example by means of LCA.Social implications– The framework brings together questions of environmental effects of ICT and global justice.Originality/value– The authors apply a rarely discussed theoretical framework to ICT and environmental sustainability. By doing this the authors suggest how the discourses and the value chain of ICT is intrinsically tied to the world system.

    2016 (Engelska)Ingår i: The Business of Gamification: A Critical Analysis / [ed] Dymek, M. & Zackariasson, P., Abingdon: Routledge, 2016, 1, s. 163-181Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    In recent years, using elements from game design in nongaming contexts, gamification, has become a major trend within the industry (Deterding et al. 2011). If we put our trust in Jane McGonigal, consultant and author of the book Reality is Broken: Why Games Make Us Better and How They Can Change the World (2011), gamification has the power to save the world due to its potential to promote desirable behaviors. Al Gore, former vice president of the U.S. and environmentalist, argues that gamification can be effective not least within the area of environmental sustainability, where saving the world is the ultimate goal. By gamifying ordinary life practices, such as recycling, energy saving and sustainable consumption, games could be “the new normal” (Gore 2011). Although gamified solutions have not been developed to a great extent within the area of sustainability yet, appli- cations that promotes energy-efficient behavior, make recycling fun and help us travel more eco-friendly do exist on the market today.

    In this chapter, we aim to describe gamification for sustainability and its challenges for developers and researchers. Furthermore, we will situate it in relation to other ways of promoting sustainable consumption, such as through raising awareness and visualization. In contrast to these two meth- ods, we argue that the main difference is that within gamification, positive, enjoyable and fun affects are mobilized in order to promote the desirable behavior. Although we tie in to the idea of using affects for the promotion of sustainable behavior, we believe that only focusing on positive affects may not be the right way for sustainable gamification. By turning to theories of the Danish philosopher Søren Kierkegaard (1813–1855), we are able to introduce new ways of conceptualizing affects in the gamification discourse. We argue that in addition to fun and enjoyment, negative or neutral affects such as anxiety could prove productive for gamification for sustainability. As games could be seen as an extension of traditional media such as books or movies (Murray 1995), we further suggest that most gamified applications fail to include important aspects that could prove useful for provoking these productive affects. By drawing on narratological game theory and combining these ideas of games with our philosophical backdrop, we develop a model for conceptualizing approaches to gamification for sustainability. We pro- pose that developers and businesses should seek alternative vistas among a plethora of opportunities presented in this chapter, rather than the most prevalent approach at present (which we call the ludo-aesthetical approach) when developing gamified applications for sustainability.

    Abstract [en]

    Traditionally, research related to Sustainable Information and Communication Technology (Sustainable ICT) has focused on the technological aspects, but there is an emerging stream of research, which looks at Sustainable ICT from the viewpoint of the social sciences. In this paper, we build on and contribute to this research by emphasizing the role of history in the shaping of Sustainable ICT. Rather than seeing the importance of history as pure technological determinism or path dependency, we draw on the historical turn in organizational studies to highlight the idea that history is malleable. This implies that organizational actors can reshape their past from the present, thus creating new conditions for the future. To highlight the importance of this theoretical conceptualization of history, we present a case study of the Nordic ICT company Tieto, where the heat recovery system of the Älvsjö data center (finished in 1978) was reconceptualized as “green” following the Green Information Technology (Green IT) trend in 2007. This way of theorizing organizational history could be used more widely within research into Sustainable ICT in order to understand why Sustainable ICT has become what it is, which also implies that we can re-interpret this history to shape the future of Sustainable ICT.

    Abstract [en]

    In this chapter we draw on the Japanese philosopher Tomonobu Imamichi in order to further develop our understanding of the relationship between Information and Communications Technology (ICT) and ecological sustainability. Our main contribution is an intuition-based approach to design for sustainability, which, for instance, means to design ICT products in a way that invokes feelings of wastefulness or misuse if used in an unsustainable manner. In contrast to persuasive approaches – which have mainly focused on raising awareness, nudging decisions, or stimulating positive behavior through gamification – we rely on the human tendency to unconsciously and effortlessly formulate mental heuristics or intuitions, when exposed to consistent feedback. The claim is that people can learn to associate perceptual cues with environmental impact, and by that will be empowered to make more sustainable choices. Based on the implications of Imamichi’s Eco-ethica, we suggest that this approach can be more fruitful for encouraging sustainable choices than both awareness raising and behavior manipulation.

    Abstract [en]

    Sustainable entrepreneurship has recently been identified as a promising force to push a sustainable business paradigm shift. A key challenge for researchers and practitioners is thus to understand and promote such practices. However, critics have argued that sustainable entrepreneurship research is heavily reductionist, in the sense that it assumes an independent and rational entrepreneur, with an exclusive focus on entrepreneurial individuals and opportunities. In this paper, we problematize these assumptions and offer an alternative theory of sustainable entrepreneurship based on ethics of care. We introduce the individual-care nexus, where individuals are assumed to be dependent, emotional, and relationally connected. This theoretical development leads to new ways to more accurately grasp the nature of motivations, emotions, traits, and practices in sustainable entrepreneurship. We illustrate our theory with an empirical case of a sustainable entrepreneur within the Green IT movement in Sweden between 2012 and 2017. We argue that our theoretical take on entrepreneurship can both advance research in sustainable entrepreneurship and provide sustainable entrepreneurs with a better understanding of their practices and a new vocabulary.

    Children’s Tablet Games: Social & Cognitive Development Stages2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Due to the increasing prevalence of tablets in families, tablets have become a major platform for computer play for pre-school children. While children may potentially learn great deal from tablet play, it is at present unclear to what extent tablets support the wide variety of play activities that characterise their play and that form a necessary basis for children's development.

    This thesis presents the results of a heuristic evaluation, inspecting the play modes that presently are supported by children’s tablet games. The evaluation focused on the extent to which the mode of play was designed to correlate with children’s stage of development. Theoretical models representing the social and cognitive stages of play were used to examine all tablet games, examining how they support solitary play, parallel play, group play, functional play and dramatic play.

    The results show that for most of the investigated games, the age declaration correlates with their supported mode of play. More specifically, the investigated games supported solitary play, group play, functional play, constructive play and dramatic play in ways that were appropriate for their target age. However, none of the games supported parallel play, which is an important play form for children between 2 to 3 years old. Furthermore, very few games supported group play and constructive play. The conclusion is that while tablet game designers seem to understand and acknowledge the cognitive development of their target users, they pay less attention to the social modes of play corresponding to children's development stages.

    When robot personalisation does not help: Insights from a robot-supported learning study2018Ingår i: Proc. 27th International Symposium on Robot and Human Interactive Communication, IEEE, 2018, s. 705-712Konferensbidrag (Refereegranskat)
    Abstract [en]

    In the domain of robotic tutors, personalised tutoring has started to receive scientists' attention, but is still relatively underexplored. Previous work using reinforcement learning (RL) has addressed personalised tutoring from the perspective of affective policy learning. However, little is known about the effects of robot behaviour personalisation on user's task performance. Moreover, it is also unclear if and when personalisation may be more beneficial than a robot that adapts to its users and the context of the interaction without personalising its behaviour. In this paper we build on previous work on affective policy learning that used RL to learn what robot's supportive behaviours are preferred by users in an educational scenario. We build a RL framework for personalisation that allows a robot to select verbal supportive behaviours to maximise the user's task progress and positive reactions in a learning scenario where a Pepper robot acts as a tutor and helps people to learn how to solve grid-based logic puzzles. A between-subjects design user study showed that participants were more efficient at solving logic puzzles and preferred a robot that exhibits more varied behaviours compared with a robot that personalises its behaviour by converging on a specific one over time. We discuss insights on negative effects of personalisation and report lessons learned together with design implications for personalised robots.

    Fast Adaptation with Meta-Reinforcement Learning for Trust Modelling in Human–Robot Interaction2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    In socially assistive robotics, an important research area is the development of adaptation techniques and their effect on human-robot interaction. We present a meta-learning based policy gradient method for addressing the problem of adaptation in human-robot interaction and also investigate its role as a mechanism for trust modelling. By building an escape room scenario in mixed reality with a robot, we test our hypothesis that bi-directional trust can be influenced by different adaptation algorithms. We found that our proposed model increased the perceived trustworthiness of the robot and influenced the dynamics of gaining human's trust. Additionally, participants evaluated that the robot perceived them as more trustworthy during the interactions with the meta-learning based adaptation compared to the previously studied statistical adaptation model.

    Investigating deep learning approaches for human-robot proxemics2018Ingår i: Proc. 27th International Symposium on Robot and Human Interactive Communication, IEEE, 2018, s. 1093-1098Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, we investigate the applicability of deep learning methods to adapt and predict comfortable human-robot proxemics. Proposing a network architecture, we experiment with three different layer configurations, obtaining three different end-to-end trainable models. Using these, we compare their predictive performances on data obtained during a human-robot interaction study. We find that our long short-term memory based model outperforms a gated recurrent unit based model and a feed-forward model. Further, we demonstrate how the created model can be used to create customized comfort zones that can help create a personalized experience for individual users.

    Abstract [en]

    Capitalization table (cap table) is a public ledger that tracks the equity ownership of a company’s shareholders. For start-up and non-public companies this information is usually stored in a spreadsheet but even after just a couple of investment rounds the cap table can become highly complex. A factor that further increases the complexity is the need for entrepreneurs and investors to use the data for analysis and calculations for future decision making. The purpose of the thesis has been to create a design hypotheses of a usable graphical user interface that allows shareholders to more clearly understand the ownership situation of the company and future scenario. To answer the research question a user-centered design approach along with a case study was applied. The case study was chosen and performed on a start-up that already offers a web service for better management of corporation documents so that real users could be part of the design process and so that their needs could be analysed. After three iterations, an end result (implemented in AngularJS and TypeScript) was obtained, which can be split into two equal parts. Firstly, a view containing a timeline of the company and its current ownership. The view can also be used to get a snapshot of the company’s ownership in a specific point in time and to simulate how future investment rounds could dilute the current shareholder’s ownership. Secondly, a view where users can simulate future exit scenarios and how much each shareholder will earn in an exit.

    An invisible burden: An experience-based approach to nurses' daily work life with healthcare information technology2019Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Information and Communication Technology (ICT) has been an increasingly pervasive component of most workplaces throughout the past half century. In healthcare, the turn to the digital has resulted into the broad implementation of Healthcare Information Technology (HIT). The impacts of ICT on work life have been investigated predominantly through surveys, although some researchers have advocated for the use of a qualitative, experience-based approach. Meanwhile, the existing body of research on the impacts of HIT on clinicians has painted a mixed picture of digitalization. Despite some clear benefits, HIT has indeed been found to have unexpected, unintended adverse consequences for hospital staff. Typical issues include loss in efficiency, extra effort to carry out routine tasks, and the creation of new, HIT-induced work activities. Simultaneously, research outside of the healthcare domain has shown that ICT could require extra effort from some users in order for the sociotechnical system to function properly – extra work often invisible to developers.

    Based on observation, interview and focus group data collected at a large Swedish hospital, this thesis set out to investigate the impact of HIT on hospital nurses from an experience-based perspective, resulting in four main contributions. First, a method supporting experience-based data analysis, the HolisticUX method, is introduced. Second, 13 forms of HIT-induced additional tasks in nurses' workload are identified, five of which are not acknowledged in previous research. Third, task avoidance is identified as a consequence of nurses' increased workload, negatively affecting patient safety, care quality and nurses' professional satisfaction. Finally, four factors are argued to contribute to a suggested invisibility of the HIT-induced time burden in nurses' work life to management and developers: 1) lack of a holistic perspective, 2) the hidden cost of a single click, 3) the invisibility of nursing work, and 4) visible data, invisible work.

    A socio-technical comparison of rail traffic control between GB and Sweden2013Ingår i: Rail Human Factors: Supporting reliability, safety and cost reduction, London: Taylor & Francis, 2013, s. 367-376Konferensbidrag (Refereegranskat)
    Abstract [en]

    There is strong motivation for having rail technology that is both international and interoperable. The practice, however, of moving technology that works well in one operational setting to another is not straightforward. This paper takes one type of technology, traffic control automation, and looks at variability between two contexts – GB and Sweden. The output from this work is a socio-technical framework which will be used to asses the viability of applying new advances in traffic management across a number of EU countries.

    Collaboration in Digital Humanities Research - Persisting Silences2018Ingår i: Digital Humanities Quarterly, ISSN 1938-4122, E-ISSN 1938-4122, Vol. 12, nr 1, artikel-id UNSP 000351Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Collaboration has become a hallmark of Digital Humanities (DH) research. Nonetheless it remains under-discussed and for those not deeply engaged in DH a bit of a mystery. Drawing on recent DH work and publications that engage with questions of DH collaboration in different ways (e.g. [Deegan and McCarthy] [Griffin and Hayler 2016] [Hayler and Griffin 2016]), we analyse three types of DH collaboration: 1) human-human interactions; 2) human-machine/material interactions; and 3) machine/material-machine/material interactions. We argue that engagement with collaboration processes and practices enables us to think through how DH tools and practices reinforce, resist, shape, and encode material realities which both pre-exist, and are co-produced by them. We suggest that understanding these entanglements facilitates a critical DH in which academic hierarchies and disciplinary preconceptions are challenged.

    Usability Design: A framework for designing usable interactive systems in practice2001Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Today many companies have started to become aware of the advantages of doing user-centred design. However, it is extremely rare that companies adopt a fully integrated user-centred design approach in one strategic shift. Rather, companies tend to adopt practices and methods in stages or adopt a particular method or practice only when a complex set of factors align to create readiness. There is a big market for companies vending usability methods, but poor usability of systems and products is still very common, the vendors often blaming it on factors outside their immediate influence. This among other things is a call for us to work for a user-centred design attitude as a major strategy for the system development process.

    The content of this thesis is dedicated to the question of how to develop usable interactive systems in practice. Main focus is on how we can raise the awareness of usability; articulate the need for user-centred design within the industry and development organisations; and practice user-centred design. A framework for usability design as an unpretentious way of applying user-centred design is described and discussed.

    The Effects of Working Memory on User’s Performance in Creative Drawing2014Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Creative thinking ability is increasingly valuable in the nowadays society, especially in the innovation industry. The way to evaluate and somehow measure human’s creativity deserved the plenty researches for decades. Among approaches for creation, drawing has been used as a support for ideation for centuries. A widely well-known creativity test was Torrance Tests of Creative Thinking (TTCT), in which creative drawing tasks took apart in. Additionally, it was proposed that creativity was a result of continuously repetitive processes of working memory and some neurophysiologists had discovered that working memory and our cerebellum collaborate to produce creativity and innovation. To expand our knowledge on the potential relationship of working memory and creativity, the problem - to what extent does a load on working memory affect creative performance in drawing tasks - therefore was addressed.The exploratory study presented in this thesis was conducted as a continuation of a series of relevant previous researches investigating how multiple factors affect the outcomes of creative drawing tasks (Zabramski & Neelakannan, 2011) (Zabramski, et al., 2011) (Zabramski, et al., 2013). A controlled experiment investigating how the outcomes of a drawing creativity test are affected when the participants are given a load on visual working memory was launched. The computerized TTCT were performed in both the experimental group and the controlled group. The load on visual working memory – the so-called Trace Fade-out setting – was only loaded for the experimental group. The Trace Fade-out setting means that what the participant has drawn on the screen will fade out until disappear in 15 seconds.This thesis presents the results of the study, which show no significant effect on creativity scores earned by the participants, in general. Specifically, relative significant differences were detected between the quality scores of the drawing outcomes obtained by the two groups. The results imply that creative drawing activities can be unaffectedly achieved in an interference of working memory, although the involved people may think they are affected during the activities and believe that they may perform better without the interference.

    Exploring Game Design Pitfalls through patterns: Experiences when making our first game2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this report is to analyze what went wrong with the adventure game project called Fairytale, I started together with 4 of my fellow university students at Gotland University, spring 2007. My ambition with this report is to enlighten problems in game design that arose during the game development process in order to prevent others from making the same mistakes.

    The problems are analyzed according to game design patterns defined by Björk, S. and Holopainen, J. (2005). Patterns in Game Design. Boston, Massachusetts. Jenifer Niles. The game was exhibited to the public at Gotland Game Awards 2007, Leipzig Game Developers Conference 2007, Tekniska Museet 2007, Almedalsveckan 2008 and Gotland Game Awards 2008.

    The results of the report show that redesigning already finished game features means a lot of troubles in relation to its dependency on other game elements. The key abilities of the main character were vaguely defined since the beginning of the project which caused problems with earlier designed levels whenever a new item was introduced. The terrain of the prior levels didn’t match the abilities of the new items, which forced changes to be made. The biggest mistake with this project was that finished game elements never were considered final.

    My role in the project was the solo game programmer and co-designer. I shared the designing tasks together with Annika Fogelgren who also was the producer of our team. Albertina Sparrhult, Emma Johansson and Marie Viberg were our core graphic artists. Together, we created the Fairytale game.

    Eye tracking technology for Automation Industry2012Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This master thesis is done at CrossControl, a company in the automation industry. A literature review was done covering state of the art technology of eye-tracking and gaze control and how it can be used in the automation industry. One purpose with the study was to indentify features important for an eye-tracker in automation applications. Findings suggests that there are no standard methods for measuring the performance of trackers and further that performance in regard to gaze control is limited by physiology of the eye rather than limitations of the devices. The differences between trackers are found in robustness when it comes to differences in people or conditions in the environment.

    A prototype was made for demonstration. The prototype was built on equipment used in the industry combined with an eye-tracker from Tobii. A library, where coordinates from the eye-tracker were used to indicate what object in the interface was gazed upon, was implemented and used to demonstrate concepts such as buttons outside the screen activated by gaze.

    Användarcentrerad utvärdering samt utveckling av ett larmsystem för vattenjet-propulsor2019Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this master thesis is to investigate how alarm systems and their visualizations, as well as signals affect work situations and decision making processes aboard vessels with water jet propulsion. Furthermore, this study aims to identify important aspects of the perception of alarm systems and which aspects that are more or less affected by stress, lack of information as well as audible and visual signals. To investigate this, the theory of Situation Awareness and the theory of Naturalistic Decision Making were used to make an analysis of which aspects that were more or less important for the users.

    The study found that the alarm system affect users a lot in their daily work. The aspect that was considered particularly important when designing a new alarm system was to have the users' everyday life in mind. Alarm systems that are based on guesses or what one thinks are appropriate for different users rarely turn out to be correct. Therefore, in order to design a correct alarm system, this situation should be taken into consideration. Other aspects that arose were the need to reduce false alarms and ordinary alarms in order to minimize the number of elements that can stress or disturb the users. In addition, audible and visual signals should not interfere more than necessary to call attention from the user. Finally, the thesis come to a conclusion with suggestions for a new alarm system based on the aspects mentioned above.

    Influencing body awareness through interactive technology in physical training: A design-oriented research in equestrian vaulting with an excursion into neuromuscular biofeedback2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Current research is underdeveloped regarding the application and development of interactive technology in instructed physical training. This includes the lack of training tools and methods targeting body awareness. Underdeveloped body awareness leads to a lack of self-confidence and the lack to relate to oneself emotionally, mentally and/or physically, as well as the inability to relate oneself to the external world. Therefore further research in this area is strongly required.

    Accordingly, this thesis deals with the questions of what types of body awareness can be designed for in a physical training context as well as how to influence the identified types through interactive technology. Reducing the thesis’ scope, the applied research concentrated on the physical training of equestrian vaulting. Therefore, a research through design approach was applied in combination with a selection of embodied interaction methods. In total, two epochés, two bodystorming workshops, two experienced prototyping sessions, one expert interview and one pilot study were conducted by focusing on an explorative, qualitative approach while putting high emphasize on the user involvement. Through the iterative development, the effect of neuromuscular biofeedback on body awareness was tested and discussed on a superficial level as one example of how interactive technology could influence body awareness.

    Overall, results identified various types of and issues with body awareness that re-occurred throughout different training situations and for which the integration of interactive technology could be beneficial. These results further lead to design implications for and insights about the design of interactive technology aiming at supporting the training of the identified body awareness issues.

    Abstract [en]

    Most currently existing tools for cognitive memory therapy require physical interaction or at least the presence of another person. The goal of this paper is to investigate whether a social robot might be an acceptable solution for a more inclusive therapy for people with memory disorder and severe physical limitations. Applying a user-centered design approach, we conducted semi-structured interviews with five healthcare professionals; four medical doctors and a psychologist, in three iterations followed by a focus group activity. An analysis of the collected data suggests several implications for design with an emphasis on embodiment, social skills, interaction, and memory training exercises.

    Portraying Empathy In Character Design2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Det här arbetet undersöker möjliga förbättringar att väcka empati genom karaktärsdesign. Metoden som används är forskning genom design, genom att samla information om emotioner, emotionell- och karaktärsdesign, och applicera det under design fasen, två nya karaktärer är skapta baserat på en existerande spel karaktär. Utvärderingen görs med hjälp av en undersökning vars slutsats är att de nya karaktärernas förmåga att väcka empati ökade drastiskt till skillnad från original karaktären. Detta var huvudsakligen på grund av deras tydligare ansiktsuttryck och kroppspråk.

    A comparative study between user research in academia and user research in commercially driven companies2015Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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.
