    Micro-expression recognition based on LBP-TOP features2017Inngår i: Nanjing Youdian Daxue Xuebao (Ziran Kexue Ban)/Journal of Nanjing University of Posts and Telecommunications (Natural Science), Vol. 37, nr 6, s. 1-7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Micro-expressions are involuntary facial expressions revealing true feelings when a person tries to conceal facial expressions.Compared with normal facial expressions,the most significant characteristic of micro-expressions is their short duration and weak intensity,thus it is diffcult to be recognized.In this paper,a micro-expression recognition method based on local binary pattern from three orthogonal plane(LBP-TOP) features and support vector machine (SVM)-based classifier is proposed.Firstly,the LBP-TOP operators are used to extract micro-expression features.Then,the feature selection algorithm combining the ReliefF with manifold learning algorithm based on locally linear embedding (LLE) is proposed to reduce the dimensionality of extracted LBP-TOP feature vectors.Finally,the SVM-based classifier with radial basis function (RBF) kernel is used to classify test samples into five categories of micro-expressions:happiness,disgust,repression,surprise,and others.Experiments are carried out on the micro-expression database CASME II using leave-one-subject-out cross validation (LOSO-CV) method.The classification accuracy can reach 58.98%.Experimental results show the effectiveness of the proposed method.

    What do we know about learner assessment in technology-rich environments?: a systematic review of systematic reviews2018Inngår i: Proceedings - IEEE 18th International Conference on Advanced Learning Technologies, ICALT 2018, Institute of Electrical and Electronics Engineers (IEEE), 2018, s. 16-20, artikkel-id 8433321Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Assessment in technology-rich environments has on one hand attracted the interest of many researchers, but on the other hand still remains an intriguing and open research issue. This paper is a systematic review of systematic reviews of studies that are focusing on the topic. The method followed included a search strategy, inclusion and exclusion criteria, and quality assessment indicators. A dedicated tool was used for the establishment of the latter. Eleven systematic reviews were included in the study. The focus of the study is in five innovative areas of interest, namely (1) adaptive or personalized learning, (2) data-informed or evidence-based approaches, (3) blending formal and informal learning, (4) cultivation of 21st century skills, and (5) game-based learning. The research questions revolve around the types of assessment used, the research methodologies or strategies, the social aspects/ planes, and future research directions.

    Profiling of English language teachers as trainees in an online course and ensuing implications2018Inngår i: Computers and education, ISSN 0360-1315, E-ISSN 1873-782X, Vol. 126, s. 1-12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The main objective of this paper is to demonstrate the importance of profiling English Language Teachers' preferences and experiences of Information and Communication Technologies (ICT) in order to inform the design of an online teacher training programme in Language Testing and Assessment and the relevant teacher training research. The findings revealed that the participant teachers received very well a variety of formats and also, they indicated methods as well as types of tasks and activities they would find most favourable in an online training course. Teachers were diverse but mediocre on average with regard to the level of confidence of their competencies in using ICT in their classrooms. Small differences were also revealed between teachers with regard to their ICT competency levels on the basis of their previous participation in online training courses but strong correlations among the different ICT competencies investigated. The findings point to the need to incorporate scaffolds in the design of online training environments that will help teachers feel confident in the online training environment and especially empower those that have not participated in such training courses before. Overall the study advocates for good practices that can be relevant and informative for higher education authorities and teacher training institutions responsible for designing (blended or online) professional training schemes for pre- and in-service English language teachers.

    From her story, to our story: Digital storytelling as public engagement around abortion rights advocacy in Ireland2018Inngår i: CHI '18 Proceedings of the 2018 CHI Conference on Human Factors in Computing Systems, Association for Computing Machinery (ACM), 2018, Vol. 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Despite the divisive nature of abortion within the Republic of Ireland and Northern Ireland, where access to safe, legal abortion is severely restricted, effecting legislative reform demands widespread public support. In light of a building pro-choice counter-voice, this work contributes to a growing body of HCI research that takes an activist approach to design. We report findings from four design workshops with 31 pro-choice stakeholders across Ireland in which we positioned an exploratory protosite, HerStoryTold, to engender critical conversations around the use of sensitive abortion narratives as a tool for engagement. Our analysis shows how digital storytelling can help reject false narratives and raise awareness of the realities of abortion laws. It suggests design directions to curate narratives that provoke empathy, foster polyvocality, and ultimately expand the engaged community. Furthermore, this research calls for designers to actively support community mobilization through providing 'stepping stones' to activism.

    Towards the study of embodied meter in Swedish folk dance2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The interrelation of playing and dancing is central for understanding performance practice in Swedish folk music, as it plays an important role for the metric and rhythmic qualities of spelmansmusik, and playing for dancing is considered a key competence for musicians in this tradition. As part of a research project into performance practice, sound, video and motion capture (MoCap) data were recorded from live performances of three musicians and two dancers in different combinations. In addition, dancing to two recordings by an influential musician and to live and pre-recorded beat clapping was recorded. This paper incorporates measurements and visualizations of performance data in combination with performer participation and interviews. As a starting point for our project, we focus on metric qualities in a historical recording, and on the dance movement patterns to a Swedish polska style with asymmetrical beat patterns. For this paper - as a preliminary investigation into the material - the recordings of one dancer dancing to an isochronous clapped beat, and to a recording by an influential player have been used for comparison of a central movement pattern in dancing. The findings show that asymmetric beat patterns contained in the recording cause wider variation among the movement patterns when compared to the patterns observed to isochronous clapping. Considering the performers reactions towards using MoCap as a tool for viewing and discussing their performances, we propose further investigations by combining scientific, ethnomusicological and artistic research methods into the research of performance practice in folk music.

    Dancing Dots - Investigating the Link between Dancer and Musician in Swedish Folk Dance2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The link between musicians and dancers is generally described as strong in many traditional musics and this holds also for Scandinavian Folk Music - spelmansmusik. Understanding the interaction of music and dance has potential for developing theories of performance strategies in artistic practice and for developing interactive systems. In this paper we investigate this link by having Swedish folk musicians perform to animations generated from motion capture recordings of dancers. The different stimuli focus on motions of selected body parts as moving white dots on a computer screen with the aim to understand how different movements can provide reliable cues for musicians. Sound recordings of fiddlers playing to the "dancing dot" were analyzed using automatic alignment to the original music performance related to the dance recordings. Interviews were conducted with musicians and comments were collected in order to shed light on strategies when playing for dancing. Results illustrate a reliable alignment to renderings showing full skeletons of dancers, and an advantage of focused displays of movements in the upper back of the dancer.

    A GDPR compliant address infrastructure mobile application for Ugandan and Rwandan users2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    More than half of the world's population are negatively affected by inadequate addresses. In Uganda and Rwanda, efforts have been done to implement a national address system but the effectiveness of those efforts have been prevented, due to lack of understanding and fears regarding its impact. With the help of Information and Communication Technology (ICT), because of its knowledge-generating foundation and substantial growth in East Africa, traditional address initiatives could be streamlined. However, negative consequences with ICT, such as surveillance, could cause the already existing reluctance to accept a system that not only registers a location but also an identity, to increase. Privacy, security and trust are therefore key factors to consider when developing a system that target areas characterized by distrust in organizations and government. This paper argues that the General Data Protection Regulation (GDPR) provides a strong framework when accomplishing this. By evaluating the user rights defined in GDPR from an interaction design perspective, this research aims to propose design guidelines that gives users agency of their personal information. This paper argues that redefining the rights as potential user actions gives the users control to manage their personal information, and further, that interest and understanding are important to enable conscious actions. With a Research through Design approach, user studies were conducted in Uganda and Rwanda, to evaluate how to design actions and information in order to enhance interest and understanding, and resulted in three design guidelines: User actions, Action layers and Information layers.

    Patients’ Experiences of Accessing Their Electronic Health Records: Results of a National Patient Survey in SwedenInngår i: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Internationally, there is a movement toward providing patients online access to their electronic health records (EHRs). In Sweden, Region Uppsala was the first to introduce patient-accessible EHRs (PAEHRs) in 2012. By the summer of 2016, 17 of 21 county councils had given citizens the possibility to access their medical information online. Studies on the effect of PAEHRs on the work environment of health care professionals have been conducted, but up until now, few extensive studies have been conducted regarding patients’ experiences of using PAEHRs in Sweden or Europe, more generally.

    Objectives: The objective of our study was to investigate patients’ experiences of accessing their EHRs through the Swedish national patient portal. In this study, we have focused on describing user characteristics, usage, and attitudes toward the system.

    Methods: A national patient survey was designed, based on previous interview and survey studies with patients and health care professionals. Data were collected during a 5-month period in 2016. The survey was made available through the PAEHR system, called Journalen, in Sweden. The total number of patients that logged in and could access the survey during the study period was 423,141. In addition to descriptive statistics reporting response frequencies on Likert scale questions, Mann-Whitney tests, Kruskal-Wallis tests, and chisquare tests were used to compare answers between different county councils as well as between respondents working in health care and all other respondents.

    Results: Overall, 2587 users completed the survey with a response rate of 0.61% (2587/423,141). Two participants were excluded from the analysis because they had only received care in a county council that did not yet show any information in Journalen. The results showed that 62.97% (1629/2587) of respondents were women and 39.81% (1030/2587) were working or had been working in health care. In addition, 72.08% (1794/2489) of respondents used Journalen about once a month, and the main reason for use was to gain an overview of one’s health status. Furthermore, respondents reported that lab results were the most important information for them to access; 68.41% (1737/2539) of respondents wanted access to new information within a day, and 96.58% (2454/2541) of users reported that they are positive toward Journalen.

    Conclusions: In this study, respondents provided several important reasons for why they use Journalen and why it is important for them to be able to access information in this way—several related to patient empowerment, involvement, and security. Considering the overall positive attitude, PAEHRs seem to fill important needs for patients.

    Inventariesystem för minskat matsvinn i hushåll: En teknisk designstudie med teoretisk grund i beteendevetenskap2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Klimatförändringen är en viktigt fråga som kräver insatser inom flera sektorer för att hållbara nivåer på växthusutsläppen ska kunna nås. En av dessa sektorer är livsmedelsindustrin där konsumtionen av livsmedel för en genomsnittlig svensk konsument utgör ca 25 % av de totala utsläppen. En förbättringsmöjlighet inom detta område är minskning av matsvinn. Denna studie fokuserar på hur ökad medvetenhet kring sitt inventarie av livsmedel inom hushåll kan bidra till minskat matsvinn samt hur man på bästa sätt kan designa ett system i detta syfte. För studien utvecklades ett digitalt inventariesystem i form av en uppkopplad skanner för inläsning av streckkoder samt en webbapplikation anpassad till mobila enheter där det aktuella inventariet presenteras tillsammans med en inköpslista. En testgrupp på åtta stycken deltagare fördelat på fyra hushåll fick under en två veckors lång period använda systemet. Efter studien fick de även delta på en intervju om deras upplevelse av- och motivation till att använda systemet, där kvalitativ data samlades in. Den grundläggande teorin bakom studien består primärt av The Behaviour Change Wheel som användes under designprocessen för det framtagna systemet då systemet skulle kräva en beteendeförändring.

    Resultatet visade en positiv inställning till systemet, där alla medverkande testpersoner ansåg att systemet skulle kunna bidra till minskat matsvinn i hushållen. Resultatet visade även att systemet underlättade kunskapsökning kring användarens inventarie av livsmedel. Det nya beteendet övergick till rutin hos majoriteten av testpersonerna och även fast en del nya funktioner och förbättringar önskades, kunde även majoriteten tänka sig att använda systemet i efterhand. Denna studie är dock i sig för kort för att kunna dra några konkreta slutsatser kring de bestående beteendeförändringar till användningen av systemet.

    Abstract [en]

    COMPUTING RESEARCHERS AND practitioners are often seen as inventing the future. As such, we are implicitly also in the business of predicting the future. We plot trajectories for the future in the problems we select, the assumptions we make about technology and societal trends, and the ways we evaluate research. However, a great deal of computing research focuses on one particular type of future, one very much like the present, only more so. This vision of the future assumes that current trajectories of ever-increasing production and consumption will continue. This focus is perhaps not surprising, since computing machinery as we know it has existed for only 80 years, in a period of remarkable industrial and technological expansion. But humanity is rapidly approaching, or has already exceeded, a variety of planet-scale limits related to the global climate system, fossil fuels, raw materials, and biocapacity. (28,32,38) It is understandable that in computing we would not focus on limits. While planetary limits are obvious in areas such as extractive capacity in mining or fishing,

    Promoting Digital Transformation in Digitally Developing Industries: A case study on strategic action points driving digital transformation in the real estate industry2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The digital transformation of businesses has come a long way; however, research and reports are showing how some industries has fallen behind in the progress. This research aimed at identifying driving factors that are essential in the progression of digitalization and use of digital capabilities. The central research question was as follows: What strategic action points should businesses within the real estate industry adopt individually and together in order to support a steady development towards becoming a digitally dextrous industry? The research was performed as a case study, using the real estate industry as an example. The case study consisted of 8 semi structured interviews, performed with representatives of various companies from the real estate value chain. Using Soule et. al.s (2016) M-PWR model as an analytical foundation, three action points, essential for businesses in digitally laggarding industries, were defined: 1. Reforming the organizational structure for better agility and empowerment of the workforce. 2. Create channels and methods encouraging collaborations between various actors. 3. Develop structured processes for identifying, extracting and managing available resources.

    Residential solar electricity adoption: how households in Sweden search for and use information2018Inngår i: Energy, Sustainability and Society, ISSN 2192-0567, Vol. 8, nr 1, artikkel-id 14Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: As a renewable energy solution, photovoltaics (PVs) are crucial in the transition to a more sustainable energy system. Besides large PV installations, household adoption of PVs will be an important contribution to this transition. However, the adoption of PVs on a household level faces many barriers, with gathering and understanding information being one of the major barriers. The aim of this article is to do an in-depth analysis of how households search for and interpret information about PVs and to discuss how to reach different groups with information. Methods: The results in this paper are based on three interview studies made between autumn 2013 and autumn 2016. In the first interview study, seven non-adopters of photovoltaics were interviewed. In the second study, seven adopters of photovoltaics were addressed. In the third study, a total of 44 households were interviewed, with a mix of non-adopters and adopters. In total, 58 households were interviewed. Results: From the interviews, we developed four ideal types for PV adoption. The non-adopters use few sources of information, find the information complicated, and have a tendency to emphasize barriers rather than enablers for PV adoptions. The environmentally engaged adopters search a lot of information but find it difficult to know when they have enough or the right information. They also find information too technical and complicated and find it hard to compare quotes. The professionally skilled group easily accesses information but also experienced problems in comparing quotes and are critical to that many problems occur during the installation process. The accidental adopters more or less happen to get a PV system and needed little information. They usually took the offer from the provider first met. Conclusions: We can conclude that when dividing the households into different ideal types, it is possible to detect what kind of information measures different groups need. To get a future increase of the number of installed PVs, it is important to develop different measures in parallel, to meet the needs from the different groups.

    Exploring the Applicability of Gamification in Online Booking Negotiation: Design Process and Evaluation2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Negotiation is an essential part of the user journey in online booking experiences, while it is often perceived as non-engaging and stressful because of the great amount of details that need to be taken care of, which would result in frustration and other negative experience. Aiming to increase the user engagement in the booking negotiation process, this study explored the applicability of gamification in an online booking negotiation tool for booking artists, by following the MDA game design framework (mechanics, dynamics, aesthetics) and taking a three-round user-centred iteration. The resulting gamification design was built as hi-fi clickable prototype and was evaluated by 30 participants with both qualitative and quantitative methods, in comparison to a prototype of conventional negotiation tool with the same functionality but without gamified elements. Although limitation existed in the study due to the given resources, the results showed an overall advantageous performance of the gamified version over the conventional version, and therefore indicated a positive influence of gamification upon user engagement, when being applied to an online booking context. The findings from the design iteration as well as the results from the final evaluation provided implications for future studies.

    From vocal sketching to sound models by means of a sound-based musical transcription system2019Inngår i: Proceedings of the 16th Sound and Music Computing Conference, Malaga, Spain, 2019, s. 1-7, artikkel-id S2.5Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper explores how notation developed for the representation of sound-based musical structures could be used for the transcription of vocal sketches representing expressive robot movements. A mime actor initially produced expressive movements which were translated to a humanoid robot. The same actor was then asked to illustrate these movements using vocal sketching. The vocal sketches were transcribed by two composers using sound-based notation. The same composers later synthesized new sonic sketches from the annotated data. Different transcriptions and synthesized versions of these were compared in order to investigate how the audible outcome changes for different transcriptions and synthesis routines. This method provides a palette of sound models suitable for the sonification of expressive body movements.

    Designing for sustainability: Breakthrough or suboptimisation?2016Inngår i: PROCEEDINGS OF ICT FOR SUSTAINABILITY 2016 / [ed] Grosso, P Lago, P Osseyran, A, ATLANTIS PRESS , 2016, s. 52-59Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Technological developments in screen technologies pitches the thinner, brighter and energy-stingy OLED screen as a possible replacement for today's television, computer and smartphone LCD screens. An OLED screen does not consume any energy at all when it displays the color black, but the potentially large energy savings can unfortunately evaporate and instead turn to losses when white is displayed. There is thus a mismatch between on the one hand the energy profiles of OLED screens and on the other hand user habits and current webpage design practices. This example thus raises important questions about system boundaries and about how to evaluate sustainable (or "sustainable") technologies. We conducted a pilot study of user acceptance of alternative, OLED-adapted color schemes for webpages. We briefly discuss the results of the study, but primarily use it as a starting point for discussing the underlying questions of where, or indeed even if it makes sense to work towards realising the OLED screens' potential for energy savings. Moving from LED to OLED screens is not only a matter of choosing between competing screen technologies, but would rather have implications for hardware and software design as well as for the practices of web designers, end users and content providers.

    Abstract [en]

    There has been an increasing interest in discussing the consequences of the technologies we invent and study in HCI. Whether it is climate change, ethical computing, capitalist and neo-liberal models of commerce and society, grassroots movements, big data or alternative paradigms in distributed systems, this workshop will invite participants to explore these consequences and ask how we move forward with responsibility and new forms of knowing and knowledge. We invite participants to join us, as we cast forward fifty years to 2068 to imagine the future of wisdom, and to reflect on how we got there. By writing Fictional Abstracts, an abstract from a research paper yet to be written, we will unpick critical tensions in the advancement of computing over the next decades. The workshop will develop perspectives on the futures of computing and critically reflect on the assumptions, methods, and tools for enabling (and disabling) such futures.

    Simplify Bidding on the Day-Ahead Electricity Market Nordpool through Structured Time-Series2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    In Sweden, electricity is purchased on a so-called day-ahead spot market (Nordpool). The electricity is based on a predicted hourly need for the upcoming day [4, 5]. Production and consumption of electricity need to be balanced since it is hard to store electricity [25]. Today, electricity companies struggle to uphold this balance using currently available tools. A potential solution would be to support bidders by visualizing time-series. Then they could identify time-series lacking data crucial to the prediction phase and resolve them. In this thesis, a prototype was implemented consisting of different views/use-cases, aimed at simplifying the bidding process for balance responsible parties (BRPs). The prototype consisted of structured time-series and presents predicted data in a way that makes the decision making easier when placing bids. Results from a study using the prototype with BRPs and professionals showed that the use-cases/views are useful in terms of 1) getting a better structure, 2) identifying incomplete time series, 3) better quality assurance of the time-series and 4) lowering the time-consumption. Additionally, the bidders suggested that the addition of references, in terms of other prediction methods than the one that was used could improve their decision making.

    Women's experience of a sexual and reproductive health chatbot2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Chatbots are increasing in popularity and interacting with humans via written language. Previous research has looked at chatbots within several domains, but not towards women’s general sexual and reproductive health. This offers a need to extend the small body of current research.  This report aimed to do so by describing women’s experiences of a sexual and reproductive health chatbot used as a decision support tool. The chatbot was designed based on a user-centered approach, allowing women to express desired personality traits in a person when discussing the topic. This resulted in the design creation of two chatbots with two different personalities. Exploratory Wizard of Oz studies were conducted with 6 users by simulating interaction with both chatbots operated by a human. Users were followed up with a survey and interview creating insights to their experiences with each chatbot. Findings resulted in contributing to research with proposed guidelines for how to design a sexual and reproductive health chatbot.

    Connecting North and South through Challenge Driven Education2018Inngår i: Proceedings of the 14th International CDIO Conference, Kanazawa, Japan, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper contributes with a north-south perspective on the ongoing enhancement of engineering education for sustainable development by giving insights in and results from implementation of challenge driven education (CDE) through joint efforts by the KTH Royal Institute of Technology, the University of Dar es Salaam (UDSM) and other African partner universities. CDE is explained as an evolution of PBL for building learning experiences around societal challenges, engaging external stakeholders, and developing students’ abilities to contribute to sustainable development. A case study is presented where students’, teachers’ and challenge owners’ perceptions of a challenge driven approach in engineering education are explored and key drivers and barriers for implementing CDE are clarified.

    Designing an interface for a teleoperated vehicle which uses two cameras for navigation.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The Swedish fire department have been wanting a robot that can be sent to situations where it’s too dangerous to send in firefighters. A teleoperated vehicle is being developed for exactly this purpose. This thesis has its base in research that previously has been conducted within Human-Robot Interaction and interface design for teleoperated vehicles. In this study, a prototype was developed to be able to simulate the experience of driving a teleoperated vehicle. It visualised the intended interface of the operator and simulated the operating experience. The development followed a User-Centered Design process and was evaluated by users. After the final evaluation a design proposal, based on previous research and user feedback, was presented. The study discusses the issues discovered when designing an interface for a teleoperated vehicle that uses two cameras for maneuvering. One challenge was how to fully utilize the two video feeds and create an interplay between them. The evaluations showed that users could keep better focus with one larger, designated main feed and the second one being placed where it can be easily glanced at. Simplicity and were to display sensor data were also shown to be important aspects to consider when trying to lower the mental load on the operator. Further modifications to the vehicle and the interface has to be made to increase the operators awareness and confidence when maneuvering the vehicle.

    RichComment: Designing an Interactive Commenting System for Visual Content in Fashion Social Networks2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    In this study, a new design of commenting system for visual contents is investigated. The aim is to explore the elements which enrich the user interaction and enhance the user experience while commenting, specifically on fashion social networks. This study explores how an improved commenting system may motivate fashion social networks’ users to express their idea about fashion products.  A speculative design approach is used as a means for investigation. A design process consisting of semi structured interviews, thematic analysis, paper prototype, online prototype and user testing is followed to design a human-centered commenting system. 

    The results suggest that providing richer tools for commenting could improve the user interaction. The most promising elements to use in fashion social media commenting system are color and pattern palettes, tagging comment and comment categorization. These elements enable fashion customers to express their ideas easier and obtain a holistic overview around other peoples’ comments.

    Apart from fashion brands’ social networks, the approach may also be more effective in fashion brand websites. People would like to have a strong impact on fashion brands. Therefore, commenting somewhere that is tightly connected to fashion brands are preferred rather than having the conversation just among themselves in social media.

    Identifying Opportunities for Digital Tools to Support Energy Advisors Working with Housing Cooperatives2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Living in the modern world is an energy-intensive activity. The residential sector accounts for almost a quarter of Sweden's total energy consumption and many buildings in Sweden are not as energy efficient as they could be. Estimations indicate that the energy consumption of the entire residential sector could be halved if improvements such as improved isolation and updated heating systems were implemented. About 65% of the total energy consumption in apartment buildings comes from heating and water heating. This makes it difficult to influence on an individual level since these systems are managed on a building level. In housing cooperatives which is common in Sweden, such changes take long time and the board managing the building usually lacks relevant competence.

    All Sweden's municipalities offer free and objective energy advisors to both individuals and companies. This paper examines, through interviews and a field study, how these energy advisors work towards housing cooperatives and if digital tools could in any way facilitate their working process.

    Four major areas of concern have been identified and a design concept that addresses these issues will be presented. The results indicate that digital tools could lead to more time and resources being put on housing cooperatives that have high potential to make energy savings and help to create longer relationships and offer the right kind of support at the right time.

    Blind deblurring using discriminative image smoothing2018Inngår i: 1st Chinese Conference on Pattern Recognition and Computer Vision, PRCV 2018, Springer Verlag , 2018, s. 490-500Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper aims to exploit the full potential of gradient-based methods, attempting to explore a simple, robust yet discriminative image prior for blind deblurring. The specific contributions are three-fold: Above all, a pure gradient-based heavy-tailed model is proposed as a generalized integration of the normalized sparsity and the relative total variation. On the second, a plug-and-play algorithm is deduced to alternatively estimate the intermediate sharp image and the nonparametric blur kernel. With the numerical scheme, image estimation is simplified to an image smoothing problem. Lastly, a great many experiments are performed accompanied with comparisons with state-of-the-art approaches on synthetic benchmark datasets and real blurry images in various scenarios. The experimental results show well the effectiveness and robustness of the proposed method.

    Nonparametric Blind Super-Resolution Using Adaptive Heavy-Tailed Priors2019Inngår i: Journal of Mathematical Imaging and Vision, ISSN 0924-9907, E-ISSN 1573-7683, Vol. 61, nr 6, s. 885-917Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Single-image nonparametric blind super-resolution is a fundamental image restoration problem yet largely ignored in the past decades among the computational photography and computer vision communities. An interesting phenomenon is observed that learning-based single-image super-resolution (SR) has been experiencing a rapid development since the boom of the sparse representation in 2005s and especially the representation learning in 2010s, wherein the high-res image is generally blurred by a supposed bicubic or Gaussian blur kernel. However, the parametric assumption on the form of blur kernels does not hold in most practical applications because in real low-res imaging a high-res image can undergo complex blur processes, e.g., Gaussian-shaped kernels of varying sizes, ellipse-shaped kernels of varying orientations, curvilinear kernels of varying trajectories. The paper is mainly motivated by one of our previous works: Shao and Elad (in: Zhang (ed) ICIG 2015, Part III, Lecture notes in computer science, Springer, Cham, 2015). Specifically, we take one step further in this paper and present a type of adaptive heavy-tailed image priors, which result in a new regularized formulation for nonparametric blind super-resolution. The new image priors can be expressed and understood as a generalized integration of the normalized sparsity measure and relative total variation. Although it seems that the proposed priors are simple, the core merit of the priors is their practical capability for the challenging task of nonparametric blur kernel estimation for both super-resolution and deblurring. Harnessing the priors, a higher-quality intermediate high-res image becomes possible and therefore more accurate blur kernel estimation can be accomplished. A great many experiments are performed on both synthetic and real-world blurred low-res images, demonstrating the comparative or even superior performance of the proposed algorithm convincingly. Meanwhile, the proposed priors are demonstrated quite applicable to blind image deblurring which is a degenerated problem of nonparametric blind SR.

    Delete by Haiku: Poetry from Old SMS Messages2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The work draws on repurposing practices to inform design for deletion and handling of digital waste – a way of letting go – in graceful and aesthetically appealing ways.

    Delete by Haiku 1 is a mobile phone application that explores how deleting old text messages can become an enjoyable and creative practice by turning messages into haiku poetry. Through the application users interactively repurpose selected old text messages on their mobile phone into a haiku poem aided by a haiku- generating algorithm. By repeatedly pinching the selected messages they break apart into words that tumble down in a Tetris like manner. Gradually words are deleted until the remaining words find their position and form a haiku.

    The video presents a walkthrough of how to interact with the application to select messages in various ways, how to apply ‘themes’ to gain some control over the generation process, and eventually share created poems with others through social media.

    Metaphone: Distinguishing Human and Machine2016Annet (Fagfellevurdert)
    Abstract [en]

    Through various forms of interaction, the Metaphone1 project asks important questions about relationship between human and machine (in the fields of interac- tive arts and Human-Computer Interaction) and how those two may interact creating artistic knowledge. Control issue is raising questions on combinations of chaos and systematic control, while one version of the art installation provides means for creating artworks through participants’ emotions and feelings (GSR and HR sensors). However, exploring ways of expression, the notion of authorship (from artistic perspective) is still in question: debating who owns the final artwork, if the machine could own the work and create artistically, is the participant still politically in charge, while finally, live creative process is always left free and open.

    Time and Space in Panoramic Photography2017Inngår i: Acoustic Space, Vol. 16, nr 4, s. 233-245Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article intends to show a usage-hacking case of everyday technology for creating visual narratives. The photographic art project “Panorama Time” is discussed through a techno-cultural perspective and examines the spatial-temporal dimension in panoramic photography, which, in this case, is a digital camera in a mobile phone. The post-media condition and its characteristic of embracing the fusion of different media in one device without specifying any single one is examined in our project through the combination of photographic and cinematographic processes combined in the mobile device. The rolling shutter feature, which is the technological core of digital cameras, enables the strip-photography technique, in our case used in a panoramic technique to deliver a set of concepts: glitch, repetition, frozen frames, and similar. Through deliberate navigation and control, the user breaks the panoramic view, and thus the project’s technique presents the distinction between fault and glitch aesthetics. We show examples and demonstrate the process of creating our digital photography art project “Panorama Time”. By showing how we hacked the digital artifact, we also discuss insights from several experiments in connection to broader photographic concepts in relation to time and space.

    How do we humanize digital interactive technology? One way is through our experience with technology. With S T R A T I C we present several post-digital concepts to discuss the relationship of the digital in regard to our human lives. We emphasize the synesthetic experience along with other aesthetic experiences and materiality issues with manifestations of the digital in the physical world, tangible approaches to sonic performances, or exposure of internal logics of technological processes.

    In this paper, we propose both exhibiting our work as an art installation and via a live performance. We regard it as being highly relevant to the topic of the TEI Arts Track exhibition: post-digital materiality at the intersection of the analog and the digital, and to its tangible aspects.

    Abstract [en]

    The Swedish Television ́s department for costumes and props is digitizing the work processes concerning the documentation, rental and storage of over two million objects. This thesis is a pilot study with the objective of investigating which design elements are crucial to ensure a smooth transition from the analog domain to the digital, in a specialized field. By utilizing core usability techniques, such as observations, workshops, paper prototypes and workload estimates, the key habits and work methods of the employees became apparent. This information was used to produce a high fidelity prototype of a search user interface, which was tested by 7 employees, followed by the NASA Task Load Index questionnaire. Results showed a statistically significant decrease in mean subjective workload and an increase in satisfaction while using the prototype.

    Abstract [en]

    In this alt.chi paper, we reflect on #CHIversity; a grassroots campaign highlighting feminist issues related to diversity and inclusion at CHI2017, and in HCI more widely. #CHIversity was operationalised through a number of activities including: collaborative cross-stitch and ‘zine’ making events; the development of a ‘Feminist CHI Programme’; and the use of a Twitter hashtag ‘#CHIversity’. These events granted insight into how diversity discourses are approached within the CHI community. From these recognitions we provide examples of how diversity and inclusion can be promoted at future SIGCHI events. These include fostering connections between attendees, discussing ‘polarizing’ research in a conservative political climate, and encouraging contributions to the growing body of HCI literature addressing feminisms and related subjects. Finally, we suggest how these approaches and benefits can translate to HCI events extending beyond CHI, where exclusion may routinely go undetected.

The interactive cushions are made of smart and interactive textiles, which acceptance has been profoundly investigated. Several studies have come to the conclusion that the most important feature for acceptance of smart and interactive textiles is the aesthetics of the textile interface. Therefore, this study investigates the question: How is integration of interactive cushions in the home environment affected by design concepts with different levels of explicit interaction and types of use cues? The method used in this study is based on constructive design research (CDR), where the design process consisted of moodboarding, sketching, prototyping and evaluation. Three prototypes were built and tested in two different user observations. The interactive cushions were considered well integrated in the home environment but there is room for improvement of usability. The evaluation showed that visual cues were the most important feature for usability but that there is a trade off between use cues and aesthetics.

    Abstract [en]

    In 2019, the mobile learning body of knowledge is extensive and much is known about the technology impacts and affordances of mobile devices in educational settings. A particular focus has now shifted toward specific tech- nologies in specific subjects. Mathematics is one such subject and tablets are one such technology that is gaining attention. This systematic review represent- ing the latest generation of tablet technology within the tablet-mediated learning in mathematics body of knowledge sought to derive evidence that supported questions into (a) what math sub-disciplines were covered, (b) what technology (application/hardware) was utilized, and (c) what pedagogical approaches were deployed in educational settings. This included analysis of the (d) advantages and (e) disadvantages present in those elements. Thirty-nine relevant articles were collected from various academic technology and educational databases. The results demonstrate that tablets are being predominantly deployed in vari- ous sub-disciplines such as Arithmetic, Computation, and Geometry with the iPad as the dominant choice for tablet hardware/applications. Pedagogical ap- proaches lean heavily on game-based learning, environment interaction, and special needs support. Technological advantages include increased collabora- tion and mathematics engagement enabled by tablet mobility and a high poten- tial for customization of solutions. Developers, teachers, and researchers need to be informed of potential challenges in designing content for tablet technology deployments in mathematics.

    Abstract [en]

    In both developing and developed countries, policies implemented by governments are affecting the health of already marginalized communities. Within the HCI community there are examples of implicit and explicit forms of health activism as well as sub-communities adopting an activist approach to address issues of social justice that ultimately influence the social determinants of health. This SIG aims to bring together these groups of HCI scholars to outline an agenda for health activism and research—identifying and highlighting characteristics of this burgeoning domain.

    The Security Awareness Paradox: A Case Study2014Inngår i: 2014 PROCEEDINGS OF THE IEEE/ACM INTERNATIONAL CONFERENCE ON ADVANCES IN SOCIAL NETWORKS ANALYSIS AND MINING (ASONAM 2014) / [ed] Wu, X Ester, M Xu, G, IEEE , 2014, s. 704-711Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Knowledge-intensive organizations are characterized by their dependency on highly skilled personnel who perform their daily work in a decentralized manner. In these organizations it is the users who make the important decisions, and therefore the organization's information security awareness is upheld by and depends on its users' combined security awareness. To assess the overall organizational security awareness it therefore becomes interesting to assess both the users' individual level of security awareness, as well as their level of consistency and conformity with regard to other users' awareness. In the present case study, 15 semi-structured interviews have been undertaken within a large telecommunication company in order to understand how significant IT security aspects are understood within the organization. The study highlights a number of perception differences where the technical IT staff and the ordinary users do not share the same understanding. It is suggested that these perception differences result from a paradoxical situation where the users' possibility to uphold security awareness is hindered because of security concerns.

    Service design to improve the contraceptive counselling at youth centers2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Sweden has a high rate of unintended pregnancies (UP) despite being a rather open society regarding sexual health education. New technology provides new possibilities to improve access by providing contraceptive consultations online, but will that lower the rate of UP? Very few studies have been done on the people working with the young women to find out what can be done to improve the quality of the contraceptive counseling. That is why this study involved two midwives practicing at a youth center at an early stage of the design process.

    Cultural Probes was used as method to better understand what needs midwives experience in their daily work. Three key findings stating the needs of the midwives were knowledge, missed appointments and trust. In addition, a service evaluation was done to investigate when and how midwives and young women interact.

    Making the contraceptive consultations available online with a digital care provider would make it more accessible for the young women and the results of this study do not contradict that hypothesis. However, availability is not the sole influencing factor on contraceptive usage. This study shows that encouragement for young women to seek general knowledge and information about contraceptives prior to the consultation is an important factor in order to improve the quality of contraceptive counselling.

    Abstract [en]

    In this paper we present the Nebula, a garment that translates intentional gestures and implicit interaction into sound. Nebula is a studded cloak made from a heavy fabric that envelopes the wearer with pendulous folds and has strong experiential qualities that were especially appreciated by performing artists. We describe the design process in detail, and highlight three material investigations that show material connections that were fundamental to the experience of the garment: How the draping and construction of the garment allowed for implicit interaction, how the studs were used both as a computational sensing material and a strong visual component, and how the sound design exploited tangible material qualities in the garment. We offer these three material investigations as contributions and discuss how material investigations more broadly can produce evocative connections in the materials available in design work, but also as a way to extract legible design intentions for other designers and researchers.

    Influence of Mindfulness Practices on Feelings of Place Illusion in Virtual Reality2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This study investigates how mindfulness influences feelingsof place illusion in Virtual Reality (VR) experiences, i.e. the feeling of being inside the mediated world that is displayed through the VR technology. To research the effects, a design called Mindsition was proposed that consist of two Virtual Environments (VEs) that transfers the user from the physicalworld to a task environment in VR and altering the user’s state of mind. In the first VE, a guided meditation exercise was introduced to bring the user to a more mindful state, changing how the mediated world was perceived. The user was then brought to the task environment to complete a task. The design was evaluated using a between-subjects experimental design in which half of the participants were exposed to the entire experience, while the other half only experienced the task environment.

    Results are inconclusive, but revealed tentative evidence that the Mindsition does increase feelings of place illusion, as participants felt more captivated by the environment and had a stronger overall feeling of ’being inside’ the VE. However, the results also show that Mindsition compromises reality judgement, i.e. how veritable the environment felt, as participants were more aware that the virtual world co-existed with the physical world. Overall, the study suggests that Mindfulness has the potential to make users more observant about various aspect of the VE and place less attention on the fact that the environment is perceived through a screen, making memories about the VR experience more vivid. Implications of these findings are discussed in relation to place illusionas well as mindfulness, and directions are given for future research.

    Using games as educational tools: An evaluation of a game for children to train facial expression recognition2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Facial expressions play a large role in non verbal communication. Research shows promising results for using games to improve facial expression recognition in children with autism spectrum disorder. Games are effective educational tools and are successful in motivating students. Using a game to improve facial expression recognition could be beneficial for all children as it reduces the risk for problematic behavior and mental health issues.

    For this study a game to train facial expression recognition to children was developed and evaluated. The goal of the evaluation was to determine which factors influence performance and engagement in the game and if there are expressions that are often identified incorrectly. Additionally the children’s attitude towards the game was evaluated.

    The results show that performance is affected by the difficulty, context and intensity. The children that showed the most engagement also performed better in the beginning of the game, however the correlation between performance and engagement is complex. Unfortunately it was not possible to evaluate the effect of rewards on the children’s engagement, but children were generally positive on the rewards. The confusion of expressions was in line with earlier research, but not as symmetrical. The players were generally positive about the game. Further research is needed to determine the long term learning effects of the game and to assess ways to engage players more.

    The self-flipped classroom concept: Underlying ideas and experiences2019Inngår i: Proceedings - Frontiers in Education Conference, FIE, Institute of Electrical and Electronics Engineers Inc. , 2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the modern fast changing world no formal education is able to provide learners with a complete set of knowledge, skills and competences that they would need to successfully compete on tomorrow's job market. Therefore, the role of universities is increasingly shifting towards provision of an environment where students have a chance to acquire lifelong learning skills. This paper presents underlying ideas of, and practical experiences with, an innovative pedagogy that addresses the lifelong learning skills acquisition along with additional benefits for science and technology students. The proposed approach, called self-flipped classroom (SFC), is built on a synergy of two pedagogies: learning through making and flipped classroom. To unveil the construct of the SFC, we discuss each of its components individually presenting appropriate theoretical grounding. We also report on our experiences from self-flipped classroom implementations in two countries, UK and Sweden, and in three different educational settings. From our work with the SFC concept we have identified four different roles the students can assume in a SFC scenario: creators, collaborators, communicators, and learners. We present our observations regarding the identified roles that have been found in the studied settings. We also outline some implications for teaching using the SFC concept and future research directions in this space.

    Collaborative content creation: Impact of media type on author behavior2018Inngår i: Proceedings of the ACM Conference on Computer Supported Cooperative Work, CSCW, Association for Computing Machinery , 2018, s. 341-344Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Modern education incorporates strong elements of collaborative learning: activities that prompt students to collaborate on completing learning tasks. In this work we investigate the relationship between media type and student collaboration and attribution patterns during collaborative content creation. We run similarity analyses on text and video artifacts submitted by students as part of collaborative exercises in an undergraduate module. Our main finding is that the same cohort of students was significantly more likely to attribute non-original content to its sources when authoring text compared to video content and when this content is not produced by a peer student. Our preliminary results based on only two media suggest that media type has a considerable impact on student collaborative behavior. We conclude that media type must be taken into consideration when designing collaborative learning exercises and addressing issues of academic integrity and copyright infringements.
