About this project
Results

Our long-term goal is the modeling, handling, and quantification of uncertainty throughout the complete visual computing process, from visual-computing specific models of uncertainty to the visual representation of, and interaction with, uncertainty information. We aim to investigate models and methods for quantifying individual sources of uncertainty, the propagation of uncertainty through the visual computing pipeline, and the impact of uncertainty on the components of the visual computing process. Furthermore, we will advance the visualization and visual analytics of uncertainty, and investigate several different application examples.

Research Questions

How can we integrate and combine the different aspects of uncertainty in the various subareas of visual computing?

How can uncertainty be modeled and propagated through the different steps of the visualization process?

What are effective ways to communicate uncertainty to humans and how can they meaningfully interact with such displays?

Which methods are best suited to evaluate uncertainty visualization, and how can we quantify human understanding of uncertainty?

Uncertainty-Aware Principal Component Analysis. The data consists of multivariate probability distributions, the plots shows the impact of different levels of variance.
