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.
