Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- We may have an intuitive understanding of what is meant by mobile data visualization. Yet, in the context of data visualization, the term mobile can be interpreted in several ways. For example, it may describe visual representations shown on devices that are inherently mobile. It may also describe visualizations meant to react to viewers who are mobile relative to the display. Alternatively, it may describe visualizations that are themselves mobile across devices and screens, or in space. In this chapter, we propose several characteristics that help us to identify and describe the scope of mobile data visualization. We focus on the characteristics that, particularly in their extremes, differentiate mobile data visualization from other forms of data visualization. These characteristics give rise to dimensions of a design space for mobile data visualization, against which instances may be classified and positioned. We discuss a number of examples to illustrate how the design space makes it possible to describe and compare mobile visualizations.

Publishing Visualization Studies as Registered Reports: Expected Benefits and Researchers’ Attitudes
- 2021
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Registered Reports are publications in which study proposals are peer reviewed and pre-accepted before the study is ran. Their adoption in other disciplines has been found to promote research quality and save time and resources. Objectives: We offer a brief introduction to Registered Reports and their expected benefits for visualization research. We then report a survey of the visualization community on their attitudes towards Registered Reports. This survey takes the form of a quasi Registered Report, the first one presented at a visualization venue as far as we know. Method: We will run an online survey that will be open from the end of August until the day of the alt.VIS workshop. Results: Most respondents expressed interest in Registered Reports as an additional submission format. Junior researchers as well as researchers with prior experience of preregistration tended to be more inclined to adopt this format. However, qualitative feedback highlights several perceived drawbacks and worries about Registered Reports, such as low suitability for some types of research, and increased workload for reviewers and authors. Conclusion: While many respondents expressed interest in (and sometimes enthusiasm for) Registered Reports, many also voiced concerns that should be considered and discussed in the community. Reproducibility: All the material is available on osf.io/4nrma/.

Studies of Part-to-Whole Glanceable Visualizations on Smartwatch Faces
- 2023
-
Ingår i: 2023 IEEE 16TH PACIFIC VISUALIZATION SYMPOSIUM, PACIFICVIS. - : IEEE COMPUTER SOC. - 9798350321241 - 9798350321258 ; , s. 187-196

Konferensbidrag (refereegranskat)abstract
- We present three studies that investigate the effectiveness of multiple glanceable part-to-whole proportion representations on smartwatch faces. Our goal was to understand how quickly and accurately people can make judgments about their progress toward multiple goals displayed in a small space. We designed our three studies with increasing external validity. The first study compared bar charts, radial bar charts, and text representations-shown with a digital time display. The second study added an analog time dial as a distractor to increase the complexity of the watch face. To emulate realistic viewing conditions, the third study investigated the effect of viewing angles. In Study 1 bar and radial bar charts outperformed text representations, in Study 2 adding an analog time dial as a distractor did not affect task performance, and in Study 3 only the most extreme angle led to some performance decrease. Supplementary material is available at https://osf.io/ad2z7/.

- It is our great pleasure to welcome you to this issue of the Proceedings of the ACM on Human-Computer Interaction, the second to focus on the contributions from the research community Interactive Surfaces and Spaces (ISS). Interactive Surfaces and Spaces increasingly pervade our everyday life, appearing in various sizes, shapes, and application contexts, offering a rich variety of ways to interact. This diverse research community explores the design, development, and use of new and emerging interactive surface technologies and interactive spaces. The call for articles for this issue on ISS attracted 77 submissions, from all over the world. This issue has 23 papers, 4 submitted in February 2021 and 19 submitted in July 2021. After the winter round, 4 (total of 19 articles, 21.1%) articles were accepted and 5 (26.3%) articles required major revisions. After the summer round, 19 (total of 58 articles, 32.8%) articles were accepted, and 18 (31,0%) articles required major revisions. The editorial committee worked hard over the two iterations of the review process, winter and summer rounds, to arrive at final decisions. In total, counting both the winter and the summer rounds, 23 articles (total of 77 articles, 29.9%) were accepted. All authors of the accepted articles are invited to present at the ISS conference from November 14--17, 2021. This issue exists because of the dedicated volunteer effort of 31 senior editors who served as Associate Chairs (ACs), 105 expert reviewers in the winter round, and 206 expert reviewers in the summer round to ensure high quality and insightful reviews for all articles. Reviewers and committee members were kept constant for papers that submitted to both rounds. The Editorial Board is presented here: https://iss.acm.org/2021/organization/editorial_board

Tidskriftsartikel (refereegranskat)abstract
- The conflux of two growing areas of technology – collaboration and visualization – into a new research direction, collaborative visualization, provides new research challenges. Technology now allows us to easily connect and collaborate with one another – in settings as diverse as over networked computers, across mobile devices, or using shared displays such as interactive walls and tabletop surfaces. Digital information is now regularly accessed by multiple people in order to share information, to view it together, to analyze it, or to form decisions. Visualizations are used to deal more effectively with large amounts of information while interactive visualizations allow users to explore the underlying data. While researchers face many challenges in collaboration and in visualization, the emergence of collaborative visualization poses additional challenges, but it is also an exciting opportunity to reach new audiences and applications for visualization tools and techniques.The purpose of this article is (1) to provide a definition, clear scope, and overview of the evolving field of collaborative visualization, (2) to help pinpoint the unique focus of collaborative visualization with its specific aspects, challenges, and requirements within the intersection of general computer-supported cooperative work and visualization research, and (3) to draw attention to important future research questions to be addressed by the community. We conclude by discussing a research agenda for future work on collaborative visualization and urge for a new generation of visualization tools that are designed with collaboration in mind from their very inception.

Supporting Data Interaction and Hybrid Asymmetric Collaboration Using Virtual Reality Within the Context of Immersive Analytics
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Immersive display and interaction technologies have rapidly evolved in recent years, offering advanced techniques compared to traditional Human-Computer Interaction. Computer-generated Virtual Environments viewed with stereoscopic depth perception and explored using 3D spatial interaction can represent more accurately how humans naturally interact in the real world. Data analysis is a promising area of application for such technologies, holding potential to promote intuitive interaction, user engagement, collaboration, and data curiosity, as well as to foster appropriate contextual visualization. Even when techniques such as Machine Learning and Data Mining assist with the analysis of data, human interpretation, contextualization, and meaning making are still needed. The design of immersive data visualization and interaction is challenging due to the complexity of the involved technologies and human factors, which calls for an interdisciplinary research effort.The focus of this thesis is to investigate means of exploration, interaction, and collaboration using Virtual Reality and 3D gestural input in immersive environments within the context of spatio-temporal data analysis. Based on existing literature as well as following an applied and interdisciplinary research approach, a design space for this type of Immersive Analytics is defined. The emphasis on spatio-temporal data is relevant across various real-world contexts and scenarios, such as sociolinguistics and climate analysis, given that data collected nowadays commonly feature descriptors of where and when they were captured. An immersive data analysis system has been implemented and evaluated across three virtual environment iterations. Two core themes from a user-centered perspective are interaction and collaboration. The design of useful and engaging 3D gestural interaction techniques support the conduction of typical analytical tasks that aid the data exploration and thus the discovery of insights. Furthermore, data analysis is seldom a solitary activity, but can be conducted in collaboration with multiple analysts, who combine their knowledge to interpret and discuss the discoveries. For this purpose, the concept of Hybrid Asymmetric Collaboration is defined, aiming to facilitate an envisioned broader analytical workflow that assumes a mixture of immersive and non-immersive interfaces (hybrid) as well as distinct user roles (asymmetric). To bridge data analysis across heterogeneous interface types, the design of visual information cues is investigated to support foundational aspects of collaboration, such as awareness, common ground, reference, and deixis.The conducted research has been empirically evaluated using a combination of standardized and custom methods in a total of six main studies. The outcomes of these studies allow for reflections and the proposal of design guidelines for collaborative data interaction in immersive spaces.

EULAR Sjögren's syndrome disease activity index (ESSDAI): a user guide.
- 2015

Ingår i: RMD Open. - : BMJ. - 2056-5933. ; 1:1, s. 000022-000022

Forskningsöversikt (refereegranskat)abstract
- The EULAR Sjögren's syndrome (SS) disease activity index (ESSDAI) is a systemic disease activity index that was designed to measure disease activity in patients with primary SS. With the growing use of the ESSDAI, some domains appear to be more challenging to rate than others. The ESSDAI is now in use as a gold standard to measure disease activity in clinical studies, and as an outcome measure, even a primary outcome measure, in current randomised clinical trials. Therefore, ensuring an accurate and reproducible rating of each domain, by providing a more detailed definition of each domain, has emerged as an urgent need. The purpose of the present article is to provide a user guide for the ESSDAI. This guide provides definitions and precisions on the rating of each domain. It also includes some minor improvement of the score to integrate advance in knowledge of disease manifestations. This user guide may help clinicians to use the ESSDAI, and increase the reliability of rating and consequently of the ability to detect true changes over time. This better appraisal of ESSDAI items, along with the recent definition of disease activity levels and minimal clinically important change, will improve the assessment of patients with primary SS and facilitate the demonstration of effectiveness of treatment for patients with primary SS.
