- We survey the space of three-dimensional mobile visualizations, that is, 3D abstract or spatial data on mobile 2D displays, or mobile head-mount augmented- and virtual-reality displays. As a playful “case study” we use a scenario from the film “Aliens,” in which a mobile, small-screen visualization device is used to track the movements of enemy aliens around a group of space marines. In this scenario, the marines are overrun by aliens in the ceiling, as their device fails to show them the height dimension of the space around them. We use this example to illustrate how different mobile and 3D interaction techniques could have prevented the misunderstanding in the movie, using both hypothetical descriptions of the improved movie action and a scientific discussion of these scenarios and their implications

- In this chapter, we briefly review the development of natural user interfaces and discuss their role in providing human-computer interaction that is immersive in various ways. Then we examine some opportunities for how these technologies might be used to better support data analysis tasks. Specifically, we review and suggest some interaction design guidelines for immersive analytics. We also review some hardware setups for data visualization that are already archetypal. Finally, we look at some emerging system designs that suggest future directions.

Uncertainty in humanities network visualization

Tidskriftsartikel (refereegranskat)abstract
- Network visualization is one of the most widely used tools in digital humanities research. The idea of uncertain or “fuzzy” data is also a core notion in digital humanities research. Yet network visualizations in digital humanities do not always prominently represent uncertainty. In this article, we present a mathematical and logical model of uncertainty as a range of values which can be used in network visualizations. We review some of the principles for visualizing uncertainty of different kinds, visual variables that can be used for representing uncertainty, and how these variables have been used to represent different data types in visualizations drawn from a range of non-humanities fields like climate science and bioinformatics. We then provide examples of two diagrams: one in which the variables displaying degrees of uncertainty are integrated into the graph and one in which glyphs are added to represent data certainty and uncertainty. Finally, we discuss how probabilistic data and what-if scenarios could be used to expand the representation of uncertainty in humanities network visualizations.

- Immersive environments offer new possibilities for exploring three-dimensional volumetric or abstract data. However, typicalmid-air interaction offers little guidance to the user in interacting with the resulting visuals. Previous work has explored the use of hapticcontrols to give users tangible affordances for interacting with the data, but these controls have either: been limited in their range andresolution; were spatially fixed; or required users to manually align them with the data space. We explore the use of a robot arm withhand tracking to align tangible controls under the user’s fingers as they reach out to interact with data affordances. We begin witha study evaluating the effectiveness of a robot-extended slider control compared to a large fixed physical slider and a purely virtualmid-air slider. We find that the robot slider has similar accuracy to the physical slider but is significantly more accurate than mid-airinteraction. Further, the robot slider can be arbitrarily reoriented, opening up many new possibilities for tangible haptic interaction withimmersive visualisations. We demonstrate these possibilities through three use-cases: selection in a time-series chart; interactiveslicing of CT scans; and finally exploration of a scatter plot depicting time-varying socio-economic data

Introduction to Mobile Data Visualization

- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background: Preterm birth and shorter duration of pregnancy are associated with increased morbidity in neonatal and later life. As the epigenome is known to have an important role during fetal development, we investigated associations between gestational age and blood DNA methylation in children. Methods: We performed meta-analysis of Illumina's HumanMethylation450-array associations between gestational age and cord blood DNA methylation in 3648 newborns from 17 cohorts without common pregnancy complications, induced delivery or caesarean section. We also explored associations of gestational age with DNA methylation measured at 4-18 years in additional pediatric cohorts. Follow-up analyses of DNA methylation and gene expression correlations were performed in cord blood. DNA methylation profiles were also explored in tissues relevant for gestational age health effects: fetal brain and lung. Results: We identified 8899 CpGs in cord blood that were associated with gestational age (range 27-42 weeks), at Bonferroni significance, P < 1.06 × 10- 7, of which 3343 were novel. These were annotated to 4966 genes. After restricting findings to at least three significant adjacent CpGs, we identified 1276 CpGs annotated to 325 genes. Results were generally consistent when analyses were restricted to term births. Cord blood findings tended not to persist into childhood and adolescence. Pathway analyses identified enrichment for biological processes critical to embryonic development. Follow-up of identified genes showed correlations between gestational age and DNA methylation levels in fetal brain and lung tissue, as well as correlation with expression levels. Conclusions: We identified numerous CpGs differentially methylated in relation to gestational age at birth that appear to reflect fetal developmental processes across tissues. These findings may contribute to understanding mechanisms linking gestational age to health effects.

- Forensic practitioners analyse intrinsic 3D data daily on 2D screens. We explore novel immersive visualisation techniques that enable digital autopsy through analysis of 3D imagery. We employ a user-centred design process involving four rounds of user feedback: (1) formative interviews eliciting opportunities and requirements for mixed-reality digital autopsies; (2) a larger workshop identifying our prototypes limitations and further use-cases and interaction ideas; (3+4) two rounds of qualitative user validation of successive prototypes of novel interaction techniques for pathologist sense-making. Overall, we find MR holds great potential to enable digital autopsy, initially to supplement physical autopsy, but ultimately to replace it. We found that experts were able to use our tool to perform basic virtual autopsy tasks, MR setup promotes exploration and sense making of cause of death, and subject to limitations of current MR technology, the proposed system is a valid option for digital autopsies, according to experts feedback. - Warning: This paper contains sensitive images which are 3D visualisation of deceased people.
