    Charged Utopia VR: Exploring Embodied Sense-making in the Virtual Space2018Inngår i: Proceedings of the Twelfth International Conference on Tangible, Embedded, and Embodied Interaction (Tei'18) / [ed] Ylva Fernaeus, Donald McMillan, Martin Jonsson, Audrey Girouard, Jakob Tholander, Association for Computing Machinery (ACM), 2018, s. 292-298Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper reports on preliminary results of a design research project that explores how spaces in virtual reality may be designed to build on qualities of embodied sensemaking. The project forms a basis for the exploration of an ethical dimension to interactions in virtual reality. This publication focuses on identifying qualities of embodied sense-making in an existing physical space, the interactive exhibition Charged Utopia. These qualities are transposed into a virtual interactive space. The translation of the qualities is done through the three main themes: Physical Movement, Resistance and Ambiguity. We present the design research process to describe how these themes were identified and transposed. We conclude with reflections that sketch ways in which we might capitalise on the opportunities offered by a virtual space, while respecting human skills in embodied sensemaking.

    Bridging the Age Gap Between Streaming Platforms: Improving User Experience for In-between Users2016Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The media consumption on the Internet is increasing rapidly and people at all ages are getting used to live in an on demand world. Due to this, streaming platforms have to appeal to a broad audience containing children, teenagers and adults. One approach to appeal a broad target audience is to divide the streaming platform into two separate platforms, where one is aiming for children and the other one, for the rest of the users.

    The aim of this thesis is to investigate how the user experience can be improved, to help users of ages 10-13 years old to find their way from one streaming plat- form, to another as they are growing up. The thesis investigate how existing streaming platforms appeal to a broad audience and determines reasons of why a gap can be created between streaming platforms. Based on interviews, work- shops, user tests as well as literature, a final prototype and a set of concluding suggestions have been produced as a result of this study.

    Översikt av konceptet Smart Grid med avseende på appliceringsmöjligheter på en vindkraftpark: Overview of the concept of Smart Grid in terms of application opportunities within a wind far2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The world is facing many problems, including limited natural resources as well as environmental and energy problems. Climate change is a fact and has a negative impact on several areas. The development of society has created the need for secure and reliable energy systems. Therefore, energy production must keep up with recent developments while limiting negative environmental impact. Although the sharp increase of renewable energy sources connecting to electrical networks creates stress on energy systems. Maintaining the standard of living and achieving sustainable energy production requires a significant increase in the efficiency of energy use. In addition, the fact that there are presently an abundance of effective ways to store electricity means, and requires, that the production, as well as consumption, of power are kept in balance at all times. One of the basic operating forces regarding the Smart Grid is to balance energy consumption in the best way possible. The intelligent networks method is also advantageous for the environment as well as the consumers and producers of electricity. Although the broad sense of the Smart Grid includes the whole power system, ranging from power generation, transmission and distribution infrastructure to all categories of consumers (domestic, commercial and industrial). Smart Grids are also techniques that enable improved business continuity, increased connectivity and also helps to improve the efficiency of the corporate network, and indirectly reduce costs for consumers. Further measures in this area include power supply and system maintenance as well as information and communication technology. This study will provide knowledge and understanding in addition to contributing ideas on how to improve the wind power plants and the electricity grid through the use of Smart Grids. The analysis is also a way to convey an overall impression of how the Smart Grid works as well as summarizing the general requirements in order to achieve the best possible performance.

    Making meals in small seasonal restaurants2018Inngår i: Journal of Culinary Science & Technology, ISSN 1542-8052, E-ISSN 1542-8044, Vol. 16, nr 1, s. 1-17Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Since restaurateurs can benefit by analyzing the production of meals, particularly with the dominant framework for meal experiences, the five aspects meal model (FAMM), this study examined FAMM’s relevance as an analytical tool for understanding meal production via field observations and interviews in eight small restaurants in a rural destination in Sweden. Results showed that FAMM’s aspect of the management control system and the factor of time are critical to the entire meal production process in restaurants. This article closes with a discussion of FAMM’s usefulness as a qualitative checklist for restaurateurs.

    Affective computing vs. usability ?: Insights of using traditional usability evaluation methods2005Inngår i: CHI 2005: Workshop on Innovative Approaches to Evaluating Affective Interfaces, 2005Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Evaluating affective interfaces in order to provide input for designers is a challenge for the CHI community. One question is to what extent traditional evaluation methods, used for evaluating traditional usability, are applicable at all, and if they need revision. The purpose of this project was to gain an understanding in how applicable traditional usability evaluation methods are in understanding people’s experiences of affective systems, in this case Entertainment web sites. Empirical techniques as well as inspection methods were used on a number of web sites. The results show that the methods are applicable but need revision. When it comes to the development of inspection methods, the challenges include finding proper heuristics to support the experts in using Heuristic Evaluation, providing conditions for experts which bridge the gap between evaluation and authentic use, developing complementary methods for use in combination with existing methods etc. In empirical evaluation of entertainment in the context of web usability, the most crucial aspect might be to consider how to arrange a setting that is as natural and authentic as possible when evaluating fun, as this seems to be important for the results. Overall, the results of the study clearly show that important aspects of affective interfaces can be

    Fun in the home: Guidelines for evaluating interactive entertainment on the web2005Inngår i: HCI International: 12th international conference on Human Computer Interaction., 2005Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In recent years, we have witnessed a dramatic change in how ICT (Information- and Communication Technologies) is used, and examples of usage of ICT are allocation of leisure time, learning, man-to-man communication, e-shopping and much more (Bradley, 2001). Today, the computer has moved to the kitchen, the living room, and even the garage, to support the activities going on there – food recipes are browsed from the kitchen and in the living room a TV-show is displaying supporting web sites for chatting, presentation of further information, voting, etc. Children have PC’s, on which they communicate with others, play games, search the web and so on. Because of this change in usage of ICT, the focus of design concerns has expanded from predominantly functional aspects of ICT systems to overall user experience. The trend towards experience has direct implications for usability evaluation. Since experience is considered an important aspect of the quality of various products, it should be evaluated. One possible, if not universally accepted, approach is to consider evaluation of experience as a case of usability evaluation. However, the existing methods cannot be employed. When the focus is on experiences rather than on more functional aspects of systems, a revision of usability methods is required. This paper presents a novel approach in how to conduct Heuristic Evaluations (Nielsen, 1993) on ICT mediating interactive entertainment. New heuristics, so called funology heuristics, were developed and empirically tested on, what is called, entertainment web sites. These funology heuristics were also combined with novel methodological approaches in order to fulfill the requirements when evaluating fun on the web.

    Satisfaction and learnability in edutainment: A usability study of the knowledge game ‘Laser Challenge’at the Nobel e-museum2003Inngår i: HCI International: 10th International Conference on Human Computer Interaction, 2003Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper is a report on the initial findings of a study conducted in the project FunTain with the main purpose to find general guidelines for edutainment games, in order to guide designers of such games. Usability evaluations, with users and experts, were conducted on the edutainment game in order to find usability problems. These findings were then analyzed and used as input in focus group meetings, held with joint teams consisting of game designers and HCI experts. The result was a proposal of a list of design guidelines. In this paper they are grouped in three general categories; (1) game experience, (2) balance between entertainment and education, and (3) general understanding. Findings indicate that users had problems in understanding the underlying model for the game as well as finding the knowledge related content. Experts, further, gave comments about feedback problems and different types of inconsistencies. Some of the implications from the findings, as discussed in the focus group, were guidelines for earning and loosing points, scoring and performance feedback and game object characteristics.

    Abstract [en]

    This paper presents an approach to analyze and re-design evaluation methods. The domain explored in this paper is evaluation methods for evaluating fun and entertainment. However, the approach presented may be applied in other domains as well. The approach is conceptually described and two examples of processes where the approach were used in practice are further discussed. As the map of IT applications and digital media is continuously redesigned, there is a constant need of re-designing evaluation methods.

    Configuring social agents2001Inngår i: HCI International: 8th International Conference on Human Computer Interaction, 2001, s. 450-454Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Social agents have recently been more frequently used in the user interface. However, so far not many studies have been conducted on what impact such interfaces have on users behavior. This paper discusses this and reports on empirical findings, which focus on impact of social agents on user behavior. We talk of social agents as interfaces that act autonomously but are related to the actions of the user. However, to really figure out what social impact these interfaces have on humans, we discuss what characteristics of social agents that should be possible to configure, in order to establish, maintain and develop a fruitful relation with the user. In order to do so, we needed to explore the impact for real users. The exploration of the impact of social agents such as BonzyBuddy the Parrot and Bob, the Paper-clip guy, was done empirically through observations and interviews with users. Based on empirical data collected in the study, a user-agent interaction model was constructed. The model illustrates three dimensions for configuration of social interfaces. Given the interaction model the two agents investigate are discussed followed by a discussion on what implications these observations has for design of social agents. Having identified the need for self-examining and selfadapting social agents and related problems we then conclude the paper and points at some future work.

    Designing artifacts for context awareness1999Inngår i: Proceedings odf the 22nd Information Systems Research Seminar in Scandinavia (IRIS 22): "Enterprise Architectures for Virtual Organisations" / [ed] Timo K. Käkölä, Jyväskylä, Finland: University of Jyväskylä, Department of computer science and information systems, Jyväskylä, Finland , 1999, Vol. 3, s. 371-380Konferansepaper (Fagfellevurdert)
    Abstract [en]

    To design support for distributed cognition is tough. A big amount of this type of systems have been designed during the years and a great number of them have failed in order to fulfill the purpose of supporting people to distribute the cognition. One reason for this may be the lack of support for the design process.

    In this article we argue that it exists a lack of theoretical framework to support these processes. We therefore try to examine two existing frameworks; Activity Theory and Distributed Cognition, in order to come up with some conclusions if, and in that case how, these two can be supportive. We also discuss likely differences in results between the two frameworks. We do this by examine the two frameworks and then we apply them to a case; an information system at a department on a hospital.

    We show upon the similarities and differences in design results and make a discussion. We finally ask ourselves whether the theories were a support for us in the design process or if an awareness of the approaches of them was enough to make a, sort of more intuitive design. If so, the theoretical frameworks, in this case, and the trouble using them, were in vain.

    Digital integration in the 3rd wave of mobile HCI: a key challenge for overcoming the inverted digital divide2018Inngår i: International Journal of Mobile Human Computer Interaction, ISSN 1942-390X, E-ISSN 1942-3918, Vol. 10, nr 2, s. 57-64Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    What does the 3rd wave of mobile computing hold for us, and what are the challenges ahead as we now move from the 1st and 2nd wave to the 3rd wave of mobile HCI? While the 1st wave enabled mobile computing on a basic level – including basic connectivity and the development of mobile devices – and while the 2nd wave was to a large extent about the development of mobile content (from digital services and apps, to services for storing our data in the cloud), the authors suggest that the 3rd wave of mobile computing is less technology-driven, but rather about what mobile computing can enable, and how mobile computing is increasingly a gateway to society at large. In this article, the authors focus specifically on this 3rd wave of mobile computing, and in particular on what they call an inverted digital divide – a state where the mobile technology is in place for its users, but where there is no access to the services in society that rely on mobile computing. In this article, the authors demonstrate this inverted digital divide through a number of examples where they show how this plays out for different groups of people where this is vital in a global world – e.g., visitors to a country such as tourists, immigrants and even people applying for asylum. The authors discuss what is needed in order to bridge this divide and they outline its implications for the further development of mobile services. In concluding this paper, the authors suggest that “digital integration” might serve as a key notion for resolving these issues as we now enter the 3rd wave of mobile HCI.

    Investigating the Modern Social Media Influenced World and its Consequences on Mental Health: How to reduce the negative effects on young women in the social media app Instagram by modifying or adding design parameters and functionality2019Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Social media is valuable when searching for information or to ease communication but what about the health risks, loss of productivity and physical activity, imaginary ideals and addiction? One third of women 16-29 years old suffer from a lower mental health and according to a large number of studies, social media has a big part in it. This study investigates how Instagram can be modified in order to reduce the nega- tive effects on young women caused by the app. Through interviews and a workshop, five concepts were produced and tested. The preferred solution for the users was to add a symbol if the image has been retouched, this was made to be able to separate the fake from the authentic uploads in Instagram. Totally removing the phone from the process was not an option since it is used in more situations like communication. Another concept that was instantly popular was the option to keep follow or unfollow recently added accounts. This makes the user aware of the content and is given the possibility to evaluate the accounts. Along with these concepts, it could be suggested that people need to be more aware of the problems caused by social media. It could also be suggested for users to work on their self-compassion, to not critique oneself too much, since fitspo-accounts affect users substantially. It is not the time spent on social media that matters but what people are actually engaging with.

    Wicked Interactions: (On the Necessity of) Reframing the 'Computer' in Philosophy and Design2015Inngår i: Techné: Research in Philosophy and Technology, ISSN 1091-8264, E-ISSN 1091-8264, Vol. 19, nr 1, s. 26-49Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The digital computational technologies that over the past decades have come to be fully integrated into nearly all aspects of human life have varying forms, scales, interactive mechanisms, functions, configurations, and interconnections. Much of this complexity and associated implications for human experience are, however, hidden by prevalent notions of ‘the computer’ as an object. In this paper, we consider how everyday digital technologies collectively mediate human experience, arguing that these technologies are better understood as fluid assemblages that have as many similarities with the infra-structural as they have properties typical for objects. We characterize these aspects in terms of ‘wicked interactions,’ drawing on and adapting the classic theory of wicked problems in design discourse that has similarly consid-ered the complexity of interactions with and within other types of social infrastructure. In doing this we emphasize the need and the potential for building up connections between philosophy of technology and design discourse, with the hope that this might further the shared goals of understanding digital technologies and their consequences and determining how to act in relation to them and their design.

    Abstract [en]

    The idea of far transfer effects in the cognitive sciences has received much attention in recent years. One domain where far transfer effects have frequently been reported is music education, with the prevailing idea that music practice entails an increase in cognitive ability (IQ). While cross-sectional studies consistently find significant associations between music practice and IQ, randomized controlled trials, however, report mixed results. An alternative to the hypothesis of cognitive transfer effects is that some underlying factors, such as shared genes, influence practice behaviour and IQ causing associations on the phenotypic level. Here we explored the hypothesis of far transfer within the framework of music practice. A co-twin control design combined with classical twin-modelling based on a sample of more than 10,500 twins was used to explore causal associations between music practice and IQ as well as underlying genetic and environmental influences. As expected, phenotypic associations were moderate (r = 0.11 and r = 0.10 for males and females, respectively). However, the relationship disappeared when controlling for genetic and shared environmental influences using the co-twin control method, indicating that a highly practiced twin did not have higher IQ than the untrained co-twin. In line with that finding, the relationship between practice and IQ was mostly due to shared genetic influences. Findings strongly suggest that associations between music practice and IQ in the general population are non-causal in nature. The implications of the present findings for research on plasticity, modularity, and transfer are discussed.

    3D Gestural Interaction for Stereoscopic Visualization on Mobile Devices2011Inngår i: Computer Analysis of Images and Patterns: 14th International Conference, CAIP 2011, PT 2 / [ed] Real, P; DiazPernil, D; MolinaAbril, H; Berciano, A; Kropatsch, W, Berlin: Springer Berlin/Heidelberg, 2011, s. 555-562Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Number of mobile devices such as smart phones or Tablet PCs has been dramatically increased over the recent years. New mobile devices are equipped with integrated cameras and large displays which make the interaction with device more efficient. Although most of the previous works on interaction between humans and mobile devices are based on 2D touch-screen displays, camera-based interaction opens a new way to manipulate in 3D space behind the device in the camera's field of view. In this paper, our gestural interaction heavily relies on particular patterns from local orientation of the image called Rotational Symmetries. This approach is based on finding the most suitable pattern from a large set of rotational symmetries of different orders which ensures a reliable detector for hand gesture. Consequently, gesture detection and tracking can be hired as an efficient tool for 3D manipulation in various applications in computer vision and augmented reality. The final output will be rendered into color anaglyphs for 3D visualization. Depending on the coding technology different low cost 3D glasses will be used for viewers.

    3D visualization of single images using patch level depth2011Inngår i: 2011 PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING AND MULTIMEDIA APPLICATIONS (SIGMAP 2011) / [ed] Barranco, AL & Tsihrintzis, G, IEEE, 2011, s. 1-6Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we consider the task of 3D photo visualization using a single monocular image. The main idea is to use single photos taken by capturing devices such as ordinary cameras, mobile phones, tablet PCs etc. and visualize them in 3D on normal displays. Supervised learning approach is hired to retrieve depth information from single images. This algorithm is based on the hierarchical multi-scale Markov Random Field (MRF) which models the depth based on the multi-scale global and local features and relation between them in a monocular image. Consequently, the estimated depth image is used to allocate the specified depth parameters for each pixel in the 3D map. Accordingly, the multi-level depth adjustments and coding for color anaglyphs is performed. Our system receives a single 2D image as input and provides a anaglyph coded 3D image in output. Depending on the coding technology the special low-cost anaglyph glasses for viewers will be used.

    Robust correction of 3D geo-metadata in photo collections by forming a photo grid2011Inngår i: 2011 International Conference on Wireless Communications and Signal Processing (WCSP), IEEE, 2011, s. 1-5Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this work, we present a technique for efficient and robust estimation of the exact location and orientation of a photo capture device in a large data set. The provided data set includes a set of photos and the associated information from GPS and orientation sensor. This attached metadata is noisy and lacks precision. Our strategy to correct this uncertain data is based on the data fusion between measurement model, derived from sensor data, and signal model given by the computer vision algorithms. Based on the retrieved information from multiple views of a scene we make a grid of images. Our robust feature detection and matching between images result in finding a reliable transformation. Consequently, relative location and orientation of the data set construct the signal model. On the other hand, information extracted from the single images combined with the measurement data make the measurement model. Finally, Kalman filter is used to fuse these two models iteratively and enhance the estimation of the ground truth(GT) location and orientation. Practically, this approach can help us to design a photo browsing system from a huge collection of photos, enabling 3D navigation and exploration of our huge data set.
