Our new article on people’s interpretations of exit sign colors in simulated emergencies was recently published in Applied Ergonomics.
We found that people were most likely to walk toward green signs in virtual environments during simulated emergencies. Yet, immediately after, they reported that exit signs in the building were red and that exit signs should be red. This surprising dissociation between walking behavior and verbal report emphasizes the importance of studying behavior in realistic environments.

Our paper on how on how people interpret colormap data visualizations was recently published in IEEE Transactions on Visualization and Computer Graphics (TVCG) and presented at InfoVis 2018.
We found that people are better at interpreting colormaps when darker colors map to larger quantities (dark-is-more bias), regardless of the background color, when colormaps do not appear to vary in opacity. Yet, when colormaps do appear to vary in opacity there is evidence for an opaque-is-more bias. These two biases work together on light backgrounds but conflict on dark backgrounds.

Our new article on color-music associations for a wide variety of genres was recently published in i-Perception.
Color-music associations can be predicted from lower-level perceptual dimensions and higher-level emotional dimensions, but evidence indicates that the lower-level correspondences are mediated by shared emotional content between the colors and the music.
How can perceptual cues help people learn to navigate novel virtual environments? How can immersive virtual reality be used for neuroscience education?
We are building a Virtual Brain that serves as a “virtual laboratory” for studying the role of color cues in virtual navigation. We are also evaluating its role as an educational tool.
Explaining Color Preferences
Why do people have color preferences? Why do color preferences differ between individuals and why do they change over time? Much of our research on answering these questions is motivated by the Ecological Valence Theory (EVT), which proposes that preference for a color is determined by preference for all objects and entities associated that color. We also evaluate other theories to test their ability to explain color preferences.
What are effective ways to describe patterns of color preferences? How can we predict people’s preferences for colors they haven’t judged? We are constructing and evaluating models built from color space dimensions in color spaces, which provide parsimonious descriptions of complex patterns of data.
To interpret information visualizations, people must determine how perceptual features (e.g., color, shape, size, texture) map onto concepts. This process is easier when the encoded mapping between perceptual features and concepts in visualizations matches people’s expectations. The questions is, what determines people’s expectations? Answering this question will enable the design of visualizations that are easier to interpret.
How can we generate color palettes for data visualization that are easy to perceive and enjoyable to experience? We are developing Colorgorical (“Color” + “categorical”) to address this question for categorical data visualizations. Designed and evaluated using empirical data, Colorgorical helps balance aesthetics and perceptual discriminability.
Data stories is a podcast on data visualization with Enrico Bertini and Moritz Stefaner.
This week’s episode, Color with Karen Schloss, featured a discussion on the use of color in information visualizations. Topics spanned issues in perception, color inference, and aesthetics.
