A Biased Tour of the Uncertainty Visualization Zoo
Understanding uncertainty is necessary to make informed decisions from data, yet predictive systems usually communicate uncertainty poorly—or not at all. I will discuss ways to combine knowledge of visualization perception, uncertainty cognition, and task requirements to design visualizations that more effectively communicate uncertainty. I will also discuss ongoing work in systematically characterizing the space of uncertainty visualization designs, tools for putting effective uncertainty communication into practice using the R programming language, and ways to communicate (difficult- or impossible-to-quantify) uncertainty in the data analysis process itself. When communicating statistical results, we must consider carefully how to communicate uncertainty in ways that people can actually use to make informed decisions; I aim to give an outline of some useful strategies, tools, and techniques for doing so.

Cognitive tools for visual communication
The invention of technologies to externalize our thoughts in visual form was transformative for human cognition and culture, enabling the development of art, writing, mathematics, and the reliable transmission of knowledge. Perhaps the most basic and versatile of these technologies is drawing. From photorealistic sketches to schematic diagrams, drawing provides a versatile medium for communicating about the visual world. How do images spanning such a broad range of appearances reliably convey meaning? Do viewers understand drawings based solely on their ability to resemble the entities they refer to (i.e., as images), or do they understand drawings based on shared but arbitrary associations with these entities (i.e., as symbols)? This talk will highlight our recent progress exploring these questions, as well as open research questions in this domain.
