    Gamification of Persuasive Systems for Sustainability2017Ingår i: Sustainable Internet and ICT for Sustainability, (SustainIT 2017) / [ed] Pereira, L., Bergés, M., Nunes, N., IEEE, 2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    This work in progress presents some initial findings concerning the use of gamification and persuasive technology in the domain of reaching a set sustainability goal by using persuasive systems. Both gamification and persuasive technology have become more pervasive elements in the research community in the domain of human-computer interaction (HCI) and information systems. This paper argues for research addressing the designing of these systems since we currently have a vague understanding of the important underlying mechanism. Sustainability is genuinely complex and the designer of a persuasive system with a set sustainability goal must consider numerous parameters when designing the artefact.

    Exploring Sustainable HCI Research Dimensions Through the Inclusive Innovation Framework2018Ingår i: This Changes Everything – ICT and Climate Change: What Can We Do? / [ed] Kreps, D., Ess, C., Leenen, L., Kimppa, K., Cham: Springer , 2018, s. 151-165Konferensbidrag (Refereegranskat)
    Abstract [en]

    When frameworks and design principles for open innovation and open sustainability innovation (OSI) were established in earlier research, their foundations were originated from the expanded concepts of universal design (UD) from human-computer interaction (HCI) in a prescriptive form. This also was the basis of an inclusive innovation framework (IIF) aiming for a sustainable information system design. In this paper the IIF originating from the concept of combining UD and open innovation (OI) in promoting information technology enabling sustainability goals was analyzed together with OI and OSI frameworks. The role of OI in formulating the IIF was thereby strengthened, which in parallel helped recognizing the extended conceptions of sustainable HCI (SHCI) and its future research path through the use of IIF.

    Managing Framing Effects in Persuasive Design for Sustainability2015Ingår i: Proceedings of the 19th International Academic MindTrek Conference (AcademicMindTrek '15) / [ed] Turunen, M, New York: Association for Computing Machinery (ACM), 2015, s. 122-129Konferensbidrag (Refereegranskat)
    Abstract [en]

    For decades, the framing effect has been a popular research topic in social psychology. A persuasive system could act in shaping the user behaviour towards sustainability, and thereby play a key role in social change. In this respect, understanding different framing effects in persuasive design is crucial, since individual framing and cognition on sustainability plays a major role in the success of persuasion. For dealing with a complex issue, such as achieving sustainability through behavioural change, persuasive design needs to reflect on the potentials of framing effects. In this paper, we have proposed a model of framing effects from which the principles of managing different framing effects of persuasive sustainability design were formulated. The principles were then shown in relations with different dimensions of sustainability and were also used to generate a design space for persuasive sustainability. The proposed model and principles are significant for realizing the effectiveness of different framing effects for the success of a persuasive sustainability.

    Sustainable Information System Design and the Role of Sustainable HCI2014Ingår i: Proceedings of the 18th International Academic MindTrek Conference (AcademicMindTrek '14): Media Business, Management, Content & Services / [ed] Lugmayr, A., Franssila, H., and Paavilainen, J., New York: Association for Computing Machinery (ACM), 2014, s. 66-73Konferensbidrag (Refereegranskat)
    Abstract [en]

    Sustainable Human Computer Interaction (HCI) is a heterogene­ous developing field of research, typically focusing on persuasive system design to influence users to behave and live more sustain­ably. So far this change of behavior towards sustainability has been limited more or less within the scope of environmental topics. This paper extends the notion of sustainable HCI beyond the ecological sphere of sustainability. This paper has followed a previous research work in which sustainable system design princi­ples were formulated without explanation of how to practice them in a system development process. Design principles originating from HCI design principles are an approach to showing how they could influence the classical system development life cycle to produce a sustainable system. A theoretical framework is proposed to explain this. Then sustainable HCI is redefined from the perspective of different parameters associated within the universal design concept from HCI.

    Universal Design as a Cause of Triggering Innovation Levels for Sustainability-A Deliberative Concept2015Ingår i: Proceedings of the 19th International Academic MindTrek Conference (AcademicMindTrek '15) / [ed] Turunen, M, New York: Association for Computing Machinery (ACM), 2015, s. 114-121Konferensbidrag (Refereegranskat)
    Abstract [en]

    Sustainability achievement through design could be seen as a connective result of design and innovation. The role of universal design (UD) for sustainability is well known, although how any innovation through this could be produced by the practice of UD is not evident. Different innovation levels could be triggered positively towards sustainability by practicing UD in an advanced way. In this paper, different innovation levels associated with sustainability achievement were scrutinized within the scope of UD. It was presented how the advance perspective of UD could have a direct impact on incrementing innovation levels of organisations, thereby ensuing sustainability. The advance concept of UD was then revisited in a deliberative way to justify the argument of the extensiveness of UD beyond the traditional scope of the accessibility domain only. Finally, the concept of sustainable human-computer interaction (HCI) was also re-explored within the context of UD and its practice.

    Endowing a robotic tutor with empathic qualities: Design and pilot evaluation2018Ingår i: International Journal of Humanoid Robotics, ISSN 0219-8436, Vol. 15, nr 6, artikel-id 1850025Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    As increasingly more research efforts are geared towards creating robots that can teach and interact with children in educational contexts, it has been speculated that endowing robots with artificial empathy may facilitate learning. In this paper, we provide a background to the concept of empathy, and how it factors into learning. We then present our approach to equipping a robotic tutor with several empathic qualities, describing the technical architecture and its components, a map-reading learning scenario developed for an interactive multitouch table, as well as the pedagogical and empathic strategies devised for the robot. We also describe the results of a pilot study comparing the robotic tutor with these empathic qualities against a version of the tutor without them. The pilot study was performed with 26 school children aged 10–11 at their school. Results revealed that children in the test condition indeed rated the robot as more empathic than children in the control condition. Moreover, we explored several related measures, such as relational status and learning effect, yet no other significant differences were found. We further discuss these results and provide insights into future directions.

    Exploring users' reactions towards tangible implicit probes for measuring human-robot engagement2017Ingår i: Social Robotics, Springer, 2017, s. 402-412Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, we present an exploratory study of the use of tangible implicit probes to gauge the user's social engagement with a robot. Our results show that users' paying attention to the robot's implicit probes is related to higher social engagement, but also that introducing implicit probes can lead to a more positive interaction with a robot. As we observed that users in our study started paying more attention to the implicit probes after they had encountered them, the need for careful design to capture changes in social engagement over time is justified here. Finally, we discuss some of the user recommendations to design better implicit probes.

    Designing for experiences with socially interactive robots2018Ingår i: Proc. 10th Nordic Conference on Human-Computer Interaction, New York: ACM Press, 2018, s. 948-951Konferensbidrag (Refereegranskat)
    Abstract [en]

    Socially interactive technologies are emerging as one of the predominant technologies of the future. In this workshop, we aim to discuss the emerging field of Social Robotic technologies with a particular focus on interaction design methodologies used in the design process. The workshop will investigate how researchers have approached designing social robots and what we can learn from the interaction design field for future designs. The main activities of the workshop will encompass two interactive sessions and a discussion panel on approaches to inspire the design of socially interactive robots. In particular, we focus on experience-driven design methods involving rituals and memorable experiences with social robots.

    Finding keys for people with mild dementia: Not just a matter of beeping and flashing2014Ingår i: Proceedings 8th International Conference on Augmented Cognition, Foundations of Augmented Cognition: Advancing Human Performance and Decision-Making through Adaptive Systems, Springer Berlin/Heidelberg, 2014, s. 315-324Konferensbidrag (Refereegranskat)
    Abstract [en]

    Searching for everyday objects are a frequent activity for most people. Misplaced keys, mobiles and other devices are a source of annoyance, and even more so, if people are affected by memory problems. Searching for objects is a frustrating activity, especially if this is a frequently recurring phenomenon. There are several existing techniques for retrieving objects, but many of them do not use the available technology to the full extent, providing solutions that are almost "good-enough" but not necessarily useable practice.

    In this paper we present a solution that is intense to be more than good-enough, and simultaneously argue that there is a need for solutions that don't only facilitate a good life for people with impairments, but that also does so with the user's emotional experience (UEX?) in focus.

    Participatory design with train drivers - a process analysis2005Ingår i: Interacting with computers, ISSN 0953-5438, E-ISSN 1873-7951, Vol. 17, nr 2, s. 147-166Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A participatory design process involving train drivers is analyzed and described in this paper. A group of six drivers were involved in the design process, and within a short period, four design iterations were completed. The present case study was the final part of a larger research project (TRAIN) investigating the train driving task including the drivers' information environment, number and nature of hours worked, work situation and work environment, and their effect on the drivers' behaviour and the train driver system safety. Although usability activities are widely used in IT development today, the users are not involved to the desired extent. This paper argues that to produce usable systems, quality time has to be spent initially to acquire knowledge of a work domain and establishing a common ground in terms of shared knowledge and a better understanding of the work context between the parties involved in system development. Our suggestions on participatory analysis and design that conclude the paper are based on the present case study including train drivers, as well as our experience from previous case studies.

    Haptics with Applications to Cranio-Maxillofacial Surgery Planning2015Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Virtual surgery planning systems have demonstrated great potential to help surgeons achieve a better functional and aesthetic outcome for the patient, and at the same time reduce time in the operating room resulting in considerable cost savings. However, the two-dimensional tools employed in these systems today, such as a mouse and a conventional graphical display, are difficult to use for interaction with three-dimensional anatomical images. Therefore surgeons often outsource virtual planning which increases cost and lead time to surgery.

    Haptics relates to the sense of touch and haptic technology encompasses algorithms, software, and hardware designed to engage the sense of touch. To demonstrate how haptic technology in combination with stereo visualization can make cranio-maxillofacial surgery planning more efficient and easier to use, we describe our haptics-assisted surgery planning (HASP) system. HASP supports in-house virtual planning of reconstructions in complex trauma cases, and reconstructions with a fibula osteocutaneous free flap including bone, vessels, and soft-tissue in oncology cases. An integrated stable six degrees-of-freedom haptic attraction force model, snap-to-fit, supports semi-automatic alignment of virtual bone fragments in trauma cases. HASP has potential beyond this thesis as a teaching tool and also as a development platform for future research.

    In addition to HASP, we describe a surgical bone saw simulator with a novel hybrid haptic interface that combines kinesthetic and vibrotactile feedback to display both low frequency contact forces and realistic high frequency vibrations when a virtual saw blade comes in contact with a virtual bone model. 

    We also show that visuo-haptic co-location shortens the completion time, but does not improve the accuracy, in interaction tasks performed on two different visuo-haptic displays: one based on a holographic optical element and one based on a half-transparent mirror. 

    Finally, we describe two prototype hand-worn haptic interfaces that potentially may expand the interaction capabilities of the HASP system. In particular we evaluate two different types of piezo-electric motors, one walking quasi-static motor and one traveling-wave ultrasonic motor for actuating the interfaces.

    Abstract [en]

    Background: Virtual surgery planning has proven useful for reconstructing head and neck defects by fibula osteocutaneous free flaps (FOFF). Benefits include improved healing, function, and aesthetics, as well as cost savings. But available virtual surgery planning systems incorporating fibula in craniomaxillofacial reconstruction simulate only bone reconstruction without considering vessels and soft tissue.

    Methods: The Haptics-Assisted Surgery Planning (HASP) system incorporates bone, vessels, and soft tissue of the FOFF in craniomaxillofacial defect reconstruction. Two surgeons tested HASP on 4 cases they had previously operated on: 3 with composite mandibular defects and 1 with a composite cervical spine defect. With the HASP stereographics and haptic feedback, using patient-specific computed tomography angiogram data, the surgeons planned the 4 cases, including bone resection, fibula design, recipient vessels selection, pedicle and perforator location selection, and skin paddle configuration.

    Results: Some problems encountered during the actual surgery could have been avoided as they became evident with HASP. In one case, the fibula reconstruction was incomplete because the fibula had to be reversed and thus did not reach the temporal fossa. In another case, the fibula had to be rotated 180 degrees to correct the plate and screw placement in relation to the perforator. In the spinal case, difficulty in finding the optimal fibula shape and position required extra ischemia time.

    Conclusions: The surgeons found HASP to be an efficient planning tool for FOFF reconstructions. The testing of alternative reconstructions to arrive at an optimal FOFF solution preoperatively potentially improves patient function and aesthetics and reduces operating room time.

    Abstract [en]

    Cranio-maxillofacial (CMF) surgery to restore normal skeletal anatomy in patients with serious trauma to the face can be both complex and time-consuming. But it is generally accepted that careful pre-operative planning leads to a better outcome with a higher degree of function and reduced morbidity in addition to reduced time in the operating room. However, today's surgery planning systems are primitive, relying mostly on the user's ability to plan complex tasks with a two-dimensional graphical interface. A system for planning the restoration of skeletal anatomy in facial trauma patients using a virtual model derived from patient-specific CT data. The system combines stereo visualization with six degrees-of-freedom, high-fidelity haptic feedback that enables analysis, planning, and preoperative testing of alternative solutions for restoring bone fragments to their proper positions. The stereo display provides accurate visual spatial perception, and the haptics system provides intuitive haptic feedback when bone fragments are in contact as well as six degrees-of-freedom attraction forces for precise bone fragment alignment. A senior surgeon without prior experience of the system received 45 min of system training. Following the training session, he completed a virtual reconstruction in 22 min of a complex mandibular fracture with an adequately reduced result. Preliminary testing with one surgeon indicates that our surgery planning system, which combines stereo visualization with sophisticated haptics, has the potential to become a powerful tool for CMF surgery planning. With little training, it allows a surgeon to complete a complex plan in a short amount of time.

    Abstract [en]

    Virtual assembly of complex objects has application in domains ranging from surgery planning to archaeology. In these domains the objective is to plan the restoration of skeletal anatomy or archaeological artifacts to achieve an optimal reconstruction without causing further damage. While graphical modeling plays a central role in virtual assembly, visual feedback alone is often insufficient since object contact and penetration is difficult to discern due to occlusion. Haptics can improve an assembly task by giving feedback when objects collide, but precise fitting of fractured objects guided by delicate haptic cues similar to those present in the physical world requires haptic display transparency beyond the performance of today’s systems. We propose a haptic alignment tool that combines a 6 Degrees of Freedom (DOF) attraction force with traditional 6 DOF contact forces to pull a virtual object towards a local stable fit with a fixed object. The object forces are integrated into a virtual coupling framework yielding a stable haptic tool. We demonstrate the use of our system on applications from both cranio-maxillofacial surgery and archaeology, and show that we can achieve haptic rates for fractured surfaces with over 5000 points.

    Abstract [en]

    Piezoelectric motors offer an attractive alternative to electromagnetic actuators in portable haptic interfaces: they are compact, have a high force-to-volume ratio, and can operate with limited or no gearing. However, the choice of a piezoelectric motor type is not obvious due to differences in performance characteristics. We present our evaluation of two commercial, operationally different, piezoelectric motors acting as actuators in two kinesthetic haptic grippers, a walking quasi-static motor and a traveling wave ultrasonic motor. We evaluate each gripper's ability to display common virtual objects including springs, dampers, and rigid walls, and conclude that the walking quasi-static motor is superior at low velocities. However, for applications where high velocity is required, traveling wave ultrasonic motors are a better option.

    Abstract [en]

    Studies indicate that haptic interaction with a computer generated virtual scene may become more intuitive by aligning (co-locating) the visual and haptic workspaces so that the visual and haptic feedback coincide as they do in the real world. Co-located haptics may gain importance when more advanced haptic interfaces, such as high-fidelity whole hand devices, become available. We describe a user study that investigates the pros and cons with physically co-located versus non-collocated haptics on two different display types: a commercial half-transparent mirror 3D display with shutter glasses and a prototype autostereoscopic display based on a Holographic Optical Element (HOE). We use two accuracy tasks with spatial accuracy as the dependent variable and one manipulation task with time as the dependent variable. The study shows that on both displays co-location significantly improves completion time in the manipulation task. However, the study shows that co-location does not improve the accuracy in the spatial accuracy tasks.

    SplineGrip - An Eight Degrees-of-Freedom Flexible Haptic Sculpting Tool2013Ingår i: ACM SIGGRAPH 2013 Posters, 2013Konferensbidrag (Refereegranskat)
    Abstract [en]

    SplineGrip is a flexible haptic sculpting tool that senses the articulation and pose (position and orientation) of the sculpting hand in eight degrees-of-freedom (DOF). The tool captures the hand articulation in two DOF, and uses a commercial haptic device to track the hand pose in six DOF and to simultaneously provide three DOF haptic feedback. The eight DOF input is mapped to the pose and shape of a virtual NURBS-based sculpting tool, offering versatile interaction with a virtual model. We capture the hand articulation in two DOF using two bend sensors with curvature dependent resistance, which are attached in two directions to a flexible plastic sheet mounted on the gimbal of the haptic device. One sensor measures the plastic sheet curvature controlled by the thumb, and the other measures the curvature controlled by the middle and ring fingers. In a neutral state, when all fingers are straight, the virtual sculpting tool takes the shape of a line segment. By bending one sensor with the middle and ring fingers, the user changes the virtual tool curvature. By bending the other sensor with the thumb, the user changes the width of the virtual tool. A curvature increase at zero width turns the line into a spline, and a width increase at zero curvature creates a plane. By bending both sensors, the user may simultaneously control the curvature and width of the NURBS surface. The user may toggle between negative and positive curvatures to make convex and concave tools. We demonstrate SplineGrip with a simple sculpting system where the user starts with a block of material and uses the virtual sculpting tool to gradually remove material; the sculpting tool is not limited to subtractive modeling, but can work with other modeling paradigms.

    Do relative positions and proxemics affect the engagement in a human–robot collaborative scenario?2016Ingår i: Interaction Studies: Social Behaviour and Communication in Biological and Artificial Systems, ISSN 1572-0373, E-ISSN 1572-0381, Vol. 17, nr 3, s. 321-347Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper investigates the effects of relative position and proxemics in the engagement process involved in Human-Robot collaboration. We evaluate the differences between two experimental placement conditions (frontal vs. lateral) for an autonomous robot in a collaborative task with a user across two different types of robot behaviours (helpful vs. neutral). The study evaluated placement and behaviour types around a touch table with 80 participants by measuring gaze, smiling behaviour, distance from the task, and finally electrodermal activity. Results suggest an overall user preference and higher engagement rates with the helpful robot in the frontal position. We discuss how behaviours and position of the robot relative to a user may affect user engagement and collaboration, in particular when the robot aims to provide help via socio-emotional bonding.

    From computer ethics to future (and information) ethics: The challenge of Nano-Bots2014Ingår i: Ethical dimensions of bio-nanotechnology: Present and future applications in telemedicine / [ed] Nuno Sotero Alves da Silva and Goncalo Jorge Morais da Costa, Hershey, PA, USA: IGI Global, 2014Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    One of the emerging technologies that is getting a lot of attention is nano-technology. In particular,in this area, the convergence of research fields of biotechnology, information technology, nanotechnologyand neuroscience (or cognitive science) is introducing nano-robots, or nano-bots. These machines promise to lead to the development of a large number potential applications in medicine,but at the same time they raise also a lot of social and ethical issues. This chapter introduces severalways to start an ethical reflection in relation to nano-bots. The traditional "computer ethics"approach and the new "future ethics" proposition are both discussed and applied to this technology.The challenges introduced by nano-bots are so complex that it is possible that the application of thePrecautionary Principle would be required. A further ethical analysis of nano-bots applications inmedicine may benefit from new methodologies and strategies such as the stakeholders' network andFloridi's "entropy (the evil of Infosphere)" concept.

    Digital citizenship and social responsibility of computer professionals2014Ingår i: Mondo Digitale, ISSN 1720-898X, Vol. XIII, nr 49, s. 1-10Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Digital revolution is taking us into the Information Society so quickly that the entire Information and Communication Technology (ICT) world has no time to reflect on new social and ethical issues. In particular this dramatic change put computer professionals in a position full of opportunities but also with new responsibilities. Computer professionals and Information Systems managers have in front of them a "rainbow" of risks and opportunities, they face a collection of ethical dilemmas and social issues that requires a deep reflection and debate among all stakehoders: universities, ICT professional organizations, ICT industry, policy makers, users and society at large. A code of ethics for computer professionals could be a good starting point for defining a collection of guidelines.

    Abstract [en]

    This paper proposes a reflection on cloud computing among users, organizations, policy makers, and providers. In particular the focus is on the social and ethical implications for organizations developing a strategy for cloud computing. Also the new roles and responsibilities of the CIOs are analyzed within the complexity of the stakeholders' network around cloud computing. The cloud opportunities but also the issues of concerns are investigated due to their importance for organizations that are more and more shifting towards virtual enterprises.

    Is the IT infrastructure future proof?2011Ingår i: The social impact of social computing / [ed] A. Bisset et al., Sheffield, UK: Sheffield Hallam University , 2011, s. 356-361Konferensbidrag (Refereegranskat)
    Abstract [en]

    The ICT infrastructure and its technological core are now becoming the critical infrastructures of our society. Our activities and processes are now relying on these platforms, they are now our social and business platforms. But are they sustainable? What are the (physical) limits to take into account when looking into the ICT future? Do the planet have enough resources to sustain the making, powering and wasting of all the electronic devices needed to support our social and business platforms in the future? This paper addresses the issue of evaluating the environmental impact of ICT. Starting from the analysis of the sustainability of one of its most celebrated "laws", the Moore's law, we analyse its entire life-cycle, from "silicon-factories", to their use in data centres, to the final destination of ICT products: recycling and reuse (trash ware) in the best case or, uncontrolled waste traffic towards poor countries with health hazards and environmental pollution, in the worst case. We introduce a new dimension in the social and ethical analysis related to ICT: the future. What are the implications of this future ethics in ICT?

    Abstract [en]

    In this paper we introduce a definition of post-Turing ICT with an initial analysis of its sustainability. At the beginning of the history of computing the attention was concentrated on the single machine: a device able to read and write a memory and able to execute different actions depending on the internal state. It was only in the 1960’s that the fifth function (after input, memory, processing and output) was introduced: the network, the capability of this single computational node to be connected and exchange data with similar machines. In the last fifty years the network has grown at an incredible speed, introducing us into the post-Turing ICT era: billions of electronic devices interconnected. ICT has now a significant environmental impact along all its lifetime phases: manufacturing (based on scarce minerals), application (based on growing power consumption) and e-waste management (with open cycles difficult to close). In this paper, we introduce relevant topics to understand whether the current ICT production and consumption paradigms are sustainable, and the social consequences and implications of such a problem for stakeholders.

    On the Complex Relationship Between ICT Systems and the Planet2018Ingår i: This Changes Everything –ICT and Climate Change: What Can We Do? / [ed] David Kreps, Charles Ess, Louise Leenen, Kai Kimppa, Springer, 2018, s. 181-187Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper addresses the challenges of designing sustainable Information and Communication Technology (ICT) systems. The complexity of ICT systems, the number of stakeholders involved (technology providers, policymakers, users, etc.), and the extension and global scale of ICT supply chain are the main challenges at the core of the complex relationship between ICT systems and the planet Earth. ICT offer an opportunity for an exchange between matter-energy and information: the better use of information offers the greatopportunity for decreasing the environmental impact of human activities by decreasing the matter and energy consumption. But, on the other side, like anyhuman activity, the design, production, use, and disposal of complex ICT systems,has as a consequence a growth in entropy. This intriguing dilemma is one of the most difficult challenges in front of designers, ICT companies, users, and policy makers. This paper concentrates on the designers, the engineers’ dilemmas: what are the ethical competences, the skills, the methods for addressing these complex ethical dilemmas? Among the many ethical approaches, the“virtue/future ethics” is proposed as a core ethical competence for the designers and engineers of the future.

    The brave new world of socio-technical systems: Cloud computing2013Ingår i: The possibilities of ethical ICT, Kolding: University of Southern Denmark , 2013, s. 377-383Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we propose an analysis of Cloud Computing as a new kind of socio-technical system. For many organizations, moving ICT from the capital expenditure line to the operational expenditure line, by using "ICT services on-demand" and paying them by consumption, is an opportunity. From another perspective Cloud Computing represents a big shift back towards centralized architectures where end-users and organizations will use on.demand resources provided by very large datacentres. Are we moving from the "autonomy" of the 1980's introduced by Personal Computing to the "heteronomy" of Cloud Computing of the XXI century? For analysing the main social and ethical issues related to Cloud Computing we propose a simple model based on the Socio-Technical Systems concept. The co-shaping between society and technology is clean-cut and can be a useful tool for users and organisations that are considering to enter into the world of ICT as-a-service. We finally investigate possible connections between our reflections about Cloud Computing and more deep ethical, philosophical, and psychological ways of addressing these issues.

    Challenging the pursuit of Moore's law: ICT sustainability in the cloud computing era2011Ingår i: Politeia, ISSN 1128-2401, Vol. 104, s. 45-55Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this paper we investigate the sustainability of Information andCommunication Technologies (ICT) from an environmental point of view. Inparticular we concentrate on two items, the ICT life cycle (manufacturing, operatingand disposing, also known as e-waste) and on the potential role of an ICTstakeholders’ network. Computers and networks are mainly based on electronicproducts, and the industrial process for producing them is one of the most complex andcostly in terms of “material intensity”. Is this process sustainable? On the other side,the emerging “cloud computing” concentrates central processing and storagecapability in a few gigantic data centres: does this contribute to the decrease orincrease of power consumption (and climate change)? How can we address the issueof e-waste? By computer return and recycling? New design principles? Openhardware? By developing smart software applications? We propose a stakeholders’network for ICT that can be useful to investigate possible strategies for addressingthese challenges.

    Slow tech is a new way of looking at technology. It means designing and developingtechnologies that are ‘slow’, with the aim of being good, clean, and fair. It has, as anaspiration, the design and use of a new kind of information and communicationtechnologies (ICT): ICT that is human-centred, and that takes into account both thelimits of the planet and those of human beings. The focus of this reflection paper is onICT that speaks to the needs of the environment and society, and is thus implicitlyethical. It contributes towards promoting slow tech to an audience of computerprofessionals and computer end-users.

    How to Make Decisions with Algorithms: Ethical Decision-Making Using Algorithms within Predictive Analytics2017Ingår i: CEPE/Ethicomp 2017: ElectronicCollection / [ed] Richard Volkman, Torino: Università degli Studi di Torino , 2017, s. 1-13Konferensbidrag (Refereegranskat)
    Abstract [en]

    The use of automated decision-making support, such as algorithms within predictive analytics,will inevitably be more and more relevant and will be affecting society. Sometimes it is good,and sometimes there seems to be negative effect, such as with discrimination. The solutionfocused on in this paper is how humans and algorithms, or ICT, could interact within ethicaldecision-making. What predictive analytics can produce is, arguably, mostly implicit knowledge,so what a human decision-maker could, possibly, help with is the explicit thought processes.This could be one way to conceptualize an interactive effect between humans and algorithms thatcould be fruitful. Presently there does not seem to be very much research regarding predictiveanalytics and ethical decisions, concerning this human-algorithm interaction. Rather it is often afocus on pure technological solutions, or with laws and regulation.

    Basic values in software development and organizational change2003Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    This thesis is to be seen as a preliminary version of my doctoral thesis. It deals with problems concerning how our basic values influence development processes, mainly within the areas of software development and organizational change. Two main foci are presented, one theoretical and one empirical. The theoretical focus deals with the question: Is there objectivity in the theoretical framework, the knowledge and the experience on which the choices of strategies are based? The empirical focus deals with the question: How can knowledge about healthy work, usability and organizational matters be put into practice in the organizational and software development process? The preliminary conclusion shows that, when put under pressure, basic values are often clearly evident, though not necessarily evident to the individual herself. The will to grasp at models or methods that follow contemporary trends increases as well. In the end, time and money control the process, and all the magnificent ideas of a system built for a better work environment have soon faded away. This loss reflects the basic values in the organization, as well as it reflects a lack of awareness of the consequences of different strategic decisions.

    Cruise tourism as a path to a sustainable future?: The ethnographic case of Gotland, Sweden2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    Cruising tourism is arguably one of the most unsustainable forms of tourism. It is ecologically unsustainable since it brings a lot of people to small places, causing environmental strain to attractions like heritage sites. It is economically unsustainable, since multinational companies drain most of the revenue away from local SMEs. It is socially unsustainable as large number of tourists for short periods of time creates places unpleasant to live in, drained of local residents. On the basis of this, cruise tourism seems to be the worst idea for achieving sustainable development. Therefore it may seem unlikely that the Island of Gotland, Sweden, chooses to put all public funding available for many years to come into a new cruising quay to attract cruise ships, and on top of it framing it in terms of sustainability. This is however the case, and the new quay was inaugurated April 29, 2018, where the mayor spoke of this will be economically, ecologically and socially sustainable, on the basis of the very high sustainability standards on Gotland. How can this be understood? To investigate how the project of building the new quay is related to sustainability; actors perception of this relationship as well as the consequences of their actions in terms of economical, social and ecological sustainability, ethnographic fieldwork over the course of two years has been carried out. During this fieldwork public and private actors involved in carrying out this project, with the basis in the DMO-like privately owned organization Gotland Tourism Business Organisation (Gotlands Förenade Besöksnäring) and the cruise tourism network Gotland Cruise Network, have been followed. On the basis of this, it seems that sustainability simultaneously becomes a tool for “green-washing”, legitimizing unsustainable practices, and at the same time a way for locals to try to make a better future for themselves through making the best possible out of this new situation. In addition, I argue that academia play a role in this, with the research programme “Sustainable Visits”, which I myself is part of, and which has as an explicit aim to contribute to, rather than merely study, sustainable visits. However, does academia contribute to sustainability or unsustainability in this case?

    Positive and Negative effects of Game Analytics in the Game Design process: A Grounded Theory Study2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Syftet med denna Grounded Theory studie är att undersöka de positiva och negativa effekterna av spelanalys och hur det kan påverka speldesign processen inom spelutvecklings processen. Detta görs genom att granska och observera tillgängligt källmaterial som är relaterat till Triple AAA spelindustrin och experter inom spelbranschen med fokus på spelanalys, spelande, speldesign och spelutveckling. Källmaterialet består av publikationer, presentationer, artiklar och föreläsningar som är direkt kopplade till ovannämnda områden som kommer att användas för att förstärka teorin.

    Genom det insamlade källmaterialet kommer teorin att utvecklas som presenterar de potentiella positiva och negativa aspekter om att använda spelanalys för att spåra spelarens beteende för att direkt påverka och eventuellt förändra speldesign processen.

    Resultaten framhäver de positiva aspekterna av att använda spelanalys i speldesign processen som tyder på att det är fördelaktigt för speldesignern att utnyttja spelarens beteenderelaterade data tagna från spelet. Detta fungerar som en kraftfull förstärkning av speldesign processen jämfört med den traditionella design processen. De negativa aspekterna har indikerat att spelanalys är en ny praxis och fortfarande kräver en hel del kunskap för att kunna användas direkt i spelet designprocessen.

    Teorin indikerar att spelanalys på väg i rätt riktning eftersom det gör det möjligt för speldesigners att få djupare förståelse om hur sina spelare beter sig för att nå sitt slutmål vilket är att skapa en bättre spelupplevelse.

    Democracy has arrived!: A model for ethical decision making of players in MMOs2012Konferensbidrag (Refereegranskat)
    Abstract [en]

    In digital games and virtual worlds, like in other digital media, the structure of the medium, its code, influences the emerging interaction and culture. A deliberate modification of this code to facilitate democratic decision making might thus lead to more meaningful interaction in games. If we see virtual worlds as learning environments this might even help players to understand and question real-world power structures. A way to modify the code of a virtual world is by extending its interface with an add-on that interacts with the application programming interface of the game. In this paper we present the design vision and theoretical framework of a digital tool for ethical decision making that will be implemented in the virtual world World of Warcraft. Its purpose will be to supply players with means to modify the power structure built into the code of this virtual world and to support more ethical and democratic decision making in the game.

    User research and opportunities for innovation: Exploring methods and tools2016Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    First-class software engineering is no longer enough for an information system product to gain success on a market. Developing successful information system products has become a challenging practice that requires an understanding of those who are going to use the products. As product innovation has become the lifeblood of companies competing in the fast- paced IT industry, the end users have ultimately become those who determine the success of these type of products. User research is conducted to gather insights of users’ contexts, behaviors and feelings when using products. It can be practiced to explore how to create products and features that end users will find useful. This thesis examines how methods and tools used in user research can expose opportunities for innovation. The study was conducted by a literature study and a case study, where user research methods were put to practice to discover opportunities for creating a concept for a new product. Emphasis was also put on studying how to provide utility when developing a new product. The case study was performed over a four month period at an e- commerce company called Swiss Clinic in Stockholm, Sweden. The study shows that opportunities for innovation in user research occur in the interplay between business, user research discoveries and iterative design and that effective communication and artifacts play essential parts for innovating successfully.

    Framtagning av ritplattestyrd penselsimulation för GIMP2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The project was intended to produce a brush simulation plugin to the image processing program GIMP which would use a 6DOF drawing tablet for user input.Too ambitious goals coupled with compability issues between the resources used resulted in that no meaningful software was produced. Experience was however obtained, and this paper is intended to give an overview of relevant concepts for- and the process ofcreating a brush simulation.
