Our long-term goal targets the adaptation of the computer-based visualization process in order to make the visualization outcome consistent with the input data and the objectives of the visualization itself. Therefore, this project contributes to addressing the key challenge of obtaining reliable visualizations. Our model of self-consistency is formulated in a quantitative fashion: how much does the visualization result deviate from the intended result? The adaptation optimizes parameters of the visualization pipeline in order to minimize the deviation, including perceptual models, techniques from computer vision, efficient optimization methods and support for multi-objective optimization.

Research Questions

How can we build an efficient optimization framework for the adaptation of self-consistent visualization techniques?

What kind of quantitative models from perceptual psychology and computer vision literature can be used to optimize the encoding of direction information in 2D visualization?

Which quantitative models are useful for optimizing animated visualizations with moving patterns?

How can we adapt the visualization to maintain the structure of relative differences or derivatives from the input data in the form of contrast of the visualization images?

How can multi-objective optimization be used for overlaid visualization of multivariate data?

Readability evaluation of node-link diagrams of trajectories using different link types, which encode the direction. Here, a repeating comet texture is used to indicate the direction. The comet texture is adapted to the human perception of direction. Furthermore, node splatting is used to indicate node locations and spatial node density.
