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?

Can we model the flow and transformation of uncertainty through the visual computing pipeline?

Can we incorporate uncertainty in the visual computing stages and represent their effects on those stages?

Can we support visual analytics of uncertainty?

Texture-based technique to visualize uncertainty of time dependend particle positions along streamlines.

Flow Radar Glyphs.
