Introduction
https://ianruginski.netlify.com I received my Ph.D from the University of Utah in Cognitive Psychology and am currently a postdoctoral fellow at the University of Zurich. Trained as a cognitive scientist, I use interdisciplinary approaches from psychology, anthropology, statistics, computer science, and geography to study visual processing, spatial cognition, navigation, and decision-making. From an applied perspective, my research investigates interactions between users and technologies with the goal of better designing computer systems for user interactivity. Specifically, I study the cognitive processing of navigation and data visualization comprehension during human-computer interaction.

Article
Uncertainty represented in visualizations is often ignored or misunderstood by the non-expert user. The National Hurricane Center displays hurricane forecasts using a track forecast cone, depicting the expected track of the storm and the uncertainty in the forecast. Our goal was to test whether different graphical displays of a hurricane forecast c...

Ensemble and summary displays are two widely used methods to represent visual-spatial uncertainty; however, there is disagreement about which is the most effective technique to communicate uncertainty to the general public. Visualization scientists create ensemble displays by plotting multiple data points on the same Cartesian coordinate plane. Des...

Research has established that GPS use negatively affects environmental learning and navigation in laboratory studies. Furthermore, the ability to mentally rotate objects and imagine locations from other perspectives (both known as spatial transformations) is positively related to environmental learning. Using previously validated spatial transforma...
Article
Full-text available
Most of our daily activities in a highly mobile digital society require timely spatial decision-making. Much of such decision-making is supported by map displays on various devices with different modalities. Spatial information visualized on maps, however, is always subject to a multitude of uncertainties. If space-time decision-makers are not info...

Past research shows consistent sex differences in survey-based spatial knowledge and wayfinding strategy. State anxiety may help to explain some of these differences. The current study tested if and how state anxiety influences sex differences in spatial learning during navigation. We used a virtual desktop spatial learning task and manipulated sta...
Conference Paper
In this work, we present several interactive visual designs for mobile visualization of severe weather events for the communication of weather hazards, their risks, uncertainty, and recommended actions. Our approach is based on previous work on uncertainty visualization [5], cognitive science [6], and decision sciences for risk management [3, 4]. W...

16 Even if we are not aware, our emotions can influence and interplay with our navigation and use of 17 mobile navigation aids. A given map display can make us feel good by reminding us of pleasant past 18 experiences, or it can make us feel frustrated because we are not able to understand the information 19 provided. Navigation aids could also mak...
Conference Paper
Full-text available
Are gender differences in spatial ability universal, or does this vary with environment? In comparing four small-scale societies (Hadza, Twe, Tsimane, Shuar) we find that gender differences in spatial ability are larger in the savanna and minimal in the tropical forest. We consider the role of mobility and landmark visibility in shaping this differ...

Behavioral performance metrics employed to assess the usability of visual displays are increasingly coupled with eye tracking measures to provide additional insights into the decision-making processes supported by visual displays. Eye tracking metrics can be coupled with users' neural data to investigate how human cognition interplays with emotions...
Article
Full-text available
Cross-cultural sex differences in mobility and harm avoidance have been widely reported, often emphasizing fitness benefits of long-distance travel for males and high costs for females. Data emerging from adults in small-scale societies, however, are challenging the assumption that female mobility is restricted during reproduction. Such findings wa...

General design principles for visualization have been relatively well-established based on a combination of cognitive and perceptual theory and empirical evaluations over the past 20 years. To determine how these principles hold up across use contexts and end-users, I argue that we should emphasize conceptual replication focused on determining prac...

Ensemble displays are increasing in popularity, as emerging research demonstrates that ensemble displays can, in some contexts, effectively and intuitively communicate traditionally difficult statistical concepts to novice viewers, such as uncertainty.
Article
Full-text available
Cognitive science has established widely used and validated procedures for evaluating working memory in numerous applied domains, but surprisingly few studies have employed these methodologies to assess claims about the impacts of visualizations on working memory. The lack of information visualization research that uses validated procedures for mea...

Joint actions require successful coordination between two or more individuals toward shared goals. Successful motor performance can be influenced by agency and anxiety; however , these factors could also serve as regulation mechanisms that enhance coordination in joint action tasks. The current experiment assessed the influence of anxiety and sense...
Article
We investigated whether anxiety influences perceptual-motor calibration in a braking to avoid a collision task. Participants performed either a discrete braking task (Experiment 1) or a continuous braking task (Experiment 2), with the goal of stopping before colliding with a stop sign. Half of participants performed the braking task after an anxiet...

Visualizing data has been touted as a method to reduce cognitive workload by externalizing cognitive processes and utilizing the human perceptual system's ability to recognize patterns [1-4]. The current study investigated whether displaying sociocultural data in an immersive 3D virtual environment improved insight generation and decision making ov...

EFA and CFA as a first step for establishing construct validity for self report measures of navigation attitudes, as well as travel constraints and travel behaviors (mobility). We demonstrate that navigation ability is a separable dimension from wanderlust (enjoyment of navigation) and navigation anxiety (a hybrid of spatial anxiety and route follo...

It may be evolutionarily adaptive for parents to imagine a dangerous outcome when offspring have potential to be harmed. However, its possible that this only generalizes to harm avoidant individuals, a trait-level individual difference measured by a subset of the multidimensional personality questionnaire. Harm avoidance has previously been shown t...
Article
Data ensembles are often used to infer statistics to be used for a summary display of an uncertain prediction. In a spatial context, these summary displays have the drawback that when uncertainty is encoded via a spatial spread, display glyph area increases in size with prediction uncertainty. This increase can be easily confounded with an increase...

Ensembles are commonly used to generate visualizations that encode uncertainty such as hurricane weather forecast displays. How- ever, when presenting forecast visualizations to the general public, the preferred method for displaying forecast ensembles is to aggregate the ensemble members and generate summary displays. One prevalent sum- mary displ...

Article
Understanding how people interpret and use visually presented uncertainty data is an important yet seldom studied aspect of data visualization applications. Current approaches in visualization often display uncertainty as an additional data attribute without a well-defined context. Our goal was to test whether different graphical displays (glyphs)...

Here is a link to our media release. I am available to talk about how to interpret hurricane forecasts and how different forecast images may lead to different decisions about evacuation or resource allocation. https://newswise.com/articles/university-of-utah-researchers-available-to-share-insights-on-how-public-interprets-hurricane-forecast-models
