Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Buildings and urban spaces increasingly incorporate artificial intelligence and new forms of interactivity, raising a wide span of research questions about the future of human experiences with, and within, built environments. We call this emerging area Human-Building Interaction (HBI) and introduce it as an interdisciplinary domain of research interfacing Human-Computer Interaction (HCI) with Architecture and Urban Design. HBI seeks to examine the involvement of HCI in studying and steering the evolution of built environments. Therefore, we need to ask foundational questions such as the following: what are the specific attributes of built environments that HCI researchers should take into account when shifting attention and scale from "artefacts" to "environments"? Are architecture and interaction design methods and processes compatible? Concretely, how can a team of interaction designers bring their tools to an architectural project, and collaborate with other stakeholders? Can and will architecture change the theory and practice of HCI? Furthermore, research in HBI should produce knowledge and practical guidelines by experimenting novel design instances that combine architecture and digital interaction. The primary aim of this article is to specify the mission, vision, and scope of research in HBI. As the introductory article to the TOCHI special issue, it also provides a summary of published manuscripts and describes their collective contribution to the development of this field.

Forskningsöversikt (refereegranskat)abstract
- In 2017, the Event Horizon Telescope (EHT) Collaboration succeeded in capturing the first direct image of the center of the M87 galaxy. The asymmetric ring morphology and size are consistent with theoretical expectations for a weakly accreting supermassive black hole of mass ∼6.5 × 109 M o˙. The EHTC also partnered with several international facilities in space and on the ground, to arrange an extensive, quasi-simultaneous multi-wavelength campaign. This Letter presents the results and analysis of this campaign, as well as the multi-wavelength data as a legacy data repository. We captured M87 in a historically low state, and the core flux dominates over HST-1 at high energies, making it possible to combine core flux constraints with the more spatially precise very long baseline interferometry data. We present the most complete simultaneous multi-wavelength spectrum of the active nucleus to date, and discuss the complexity and caveats of combining data from different spatial scales into one broadband spectrum. We apply two heuristic, isotropic leptonic single-zone models to provide insight into the basic source properties, but conclude that a structured jet is necessary to explain M87's spectrum. We can exclude that the simultaneous γ-ray emission is produced via inverse Compton emission in the same region producing the EHT mm-band emission, and further conclude that the γ-rays can only be produced in the inner jets (inward of HST-1) if there are strongly particle-dominated regions. Direct synchrotron emission from accelerated protons and secondaries cannot yet be excluded.

Transforming knowledge systems for life on Earth : Visions of future systems and how to get there
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent.

Tinkering with Interactive Materials : Studies, Concepts and Prototypes
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The concept of tinkering is a central practice within research in the field of Human Computer Interaction, dealing with new interactive forms and technologies. In this thesis, tinkering is discussed not only as a practice for interaction design in general, but as an attitude that calls for a deeper reflection over research practices, knowledge generation and the recent movements in the direction of materials and materiality within the field. The presented research exemplifies practices and studies in relation to interactive technology through a number of projects, all revolving around the design and interaction with physical interactive artifacts. In particular, nearly all projects are focused around robotic artifacts for consumer settings. Three main contributions are presented in terms of studies, prototypes and concepts, together with a conceptual discussion around tinkering framed as an attitude within interaction design. The results from this research revolve around how grounding is achieved, partly through studies of existing interaction and partly through how tinkering-oriented activities generates knowledge in relation to design concepts, built prototypes and real world interaction.

Theory and practice in ux research : uneasy bedfellows?
- 2013

Konferensbidrag (refereegranskat)abstract
- We believe that it is time to talk about user experience and its theoretical roots as well as about the relationship between theory and practice in UX research. Although user experience is overused as a buzzword, it defines a main step change in the evolvement of the HCI field and deserves a proper (theoretical) attention. Within this panel we follow up on discussions on the theoretical foundations and the value of theory for HCI and UX research from over the last years. In particular we want to go a step further and strengthen the interdisciplinary dialogue on the relationship between theory and practice when talking about user experience. We invited panelists from academia and industry to join a fruitful dialogue talking about the different perspectives on user experience, theoretical roots, and the relevance of theory for practice and vice versa. Two moderators will ensure that the audience gets their beliefs and thoughts across to the panelists as well.

Challenges in Designing Seamless Learning Scenarios: Affective and Emotional Effects on External Representations
- 2011
-
Ingår i: International Journal of Mobile Learning and Organisation. - : InderScience Publishers. - 1746-725X .- 1746-7268. ; 5:1, s. 15-27

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we revisit different theoretical and conceptual issues that have been influencing the design of educational technology artefacts. In particular, we take into consideration recent perspectives in cognitive science that acknowledge the important effects of external representations (ERs) in learning and discuss the challenges regarding the applicability of these ideas in connection to seamless-learning environments. Extending the previous work revised here, this paper suggests that in order to further understand the nature of learning in these novel contexts, research needs to investigate how socio-affective factors come to the fore and influence the co-construction and use of ERs 'in the wild'.

A Design Toolkit for Emerging Learning Landscapes Supported by Ubiquitous Computing
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The widespread use of mobile devices and their integration in our everyday ac- tivities is changing the way we communicate, share information, and learn. The rapid adoption of powerful mobile devices also offers new opportunities to sup- port teaching and learning. For many users, mobile devices along with different types of computers are always connected, providing a constant stream of digital content to and from people and thereby adding new layers to the everyday in- formation landscape. These emergent trends are changing communication and collaboration patterns, but they have not yet been effectively leveraged for the field of education. Nearly 20 years ago, it was argued that the limitations of computer use for education in the coming decades would likely be less a result of technological limitations than a result of limited human imagination and the constraints of old habits and social structures. These two latest behaviors are still observable in many of today's classrooms. Therefore, different strategies are needed to explore and promote innovative educational practices supported by mobile and ubiquitous technologies, and this thesis will argue that design can be the catalyst for such a change.The main research question to be addressed in this thesis relates to what new approaches can be developed to design emerging learning landscapes supported by ubiquitous computing. In order to investigate this question, different design approaches are used to bring together the perspectives of technology- enhanced learning, ubiquitous computing, and interaction design. The empirical work presented in this dissertation is based on the activities and outcomes that emerged from three projects that included informal learning activities, inquiry-based science learning, and mathematics learning inside and outside the formal classroom. The most salient design approaches were identified from a comparative analysis of the projects, and this provided the foundations of a design toolkit. The intention of creating and using such a design toolkit is to provide a set of guidelines for researchers, designers, teachers, and other stakeholders to tackle the challenges of designing innovative learning activities supported by ubiquitous technologies.

MagiBricks: Fostering Intergenerational Connectedness in Distributed Play with Smart Toy Bricks
- 2023
-
Ingår i: Proceedings of IDC 2023 - 22nd Annual ACM Interaction Design and Children Conference: Rediscovering Childhood. ; , s. 239-252
-
Konferensbidrag (refereegranskat)abstract
- Playing together is crucial to the unique and invaluable bond between grandparents and grandchildren. However, co-located interactions and play can be limited due to time, distance, or pandemic-related restrictions. To facilitate distributed play, we developed MagiBricks, a system comprised of 3D-printed smart toy bricks and baseplates that provide feedback regarding their placement. The familiarity and appeal of toy bricks to both older adults and children make them ideal for intergenerational play. We conducted a within-subjects study with six grandparent-grandchildren pairs. We compared the interactions and perceived connectedness of the pairs while playing over a distance with either i) MagiBricks or ii) identical regular toy bricks. We found that MagiBricks affected communication dynamics, role taking, nature of play, and perception of connectedness during playtime compared to regular bricks, and were unanimously preferred. We contribute design implications for future systems leveraging (smart) tangibles and fostering intergenerational connectedness.

MoodGems: Designing for the Well-being of Children with ADHD and their Families at Home
- 2024
-
Ingår i: Proceedings of ACM Interaction Design and Children Conference: Inclusive Happiness, IDC 2024. ; , s. 480-494
-
Konferensbidrag (refereegranskat)abstract
- Many technologies for ADHD children and their caregivers focus on symptom management rather than overall well-being, often without involving them as technology co-designers and co-users. To explore how to design systems that integrate into their home and routines, we contribute the iterative design of MoodGems, a situated, modular, and portable set of physical displays, that allows children to record and share their data with their families. We conducted an online formative evaluation (n = 22) with ADHD children, parents, therapists, and HCI experts. Our work demonstrates the potential of technologies affording both individual and joint tracking to allow children to navigate and reflect on their experiences and emotions, and support family communication and children's autonomy. The evaluation also uncovered necessary refinements in the system's design. We contribute design insights towards technologies that empower ADHD children and integrate into their homes, and discuss therapists' role in technologies that address ADHD families' lived experiences.
