The EuroVis Workshop on Trustworthy Visualization (TrustVis), formerly known as EuroRVVV, will be held as a co-located event with EuroVis 2019 on June 3rd in Porto, Portugal.

TrustVis is a continuation of the EuroRVVV workshop, which was held six times in conjunction with EuroVis and IEEE VIS. TrustVis includes the topics covered by EuroRVVV – Reproducibility, Verification, and Validation in visualization – and also widens the scope.

We use the term “trust” in a broad sense. As a user, trust in a visualization might mean that:

• It shows the numbers I know from my spreadsheets (a common use case in industry)
• I understand how it is showing the data and I know how to interpret it (HCI, perception, etc.)
• It shows results that I can verify or validate by some means (verification, validation)
• It employs methods that are based on sound research (reproducibility of research)
• If I get sued for a decision I make based on this, I will be able to use it as evidence that I did nothing wrong (reproducibility of decisions)
• It shows me the limits of what my data and/or models can provide (uncertainty)

Topics we are looking for in the TrustVis workshop include, but are not limited to:

• Verification and validation in visualization
• Reproducibility of visualization methods and decision making
• Ways to improve trust in visualization
• Uncertainty visualization
• Ways to attack visualization (adversarial visualization)

We welcome short paper contributions, which will be peer-reviewed in a one-stage process by an international program committee. They will be electronically archived in the Eurographics Digital Library and are fully citable publications. Submissions for the TrustVis track should be no longer than 4 pages for the main content, plus one page for references. All accepted papers will be presented at the workshop.

Besides regular short papers, we also welcome short position papers, where authors have an opportunity to state opinions, present controversial arguments, show on-going work, or share thoughts for future directions.

We are very pleased to announce that Prof. Dr. Rüdiger Westermann, head of the chair for Computer Graphics and Visualization and one of the main drivers of the Visual Computing and Computer Games initiatives at Technische Universität München, Germany, has agreed to give a keynote at this year’s EuroRV³ workshop. One of the many exciting research topics that Rüdiger is working on uncertainty and Ensemble Visualization, and his keynote will be on this very topic:
“Ensemble Visualization – Visualizing the uncertainty that is represented by an ensemble of fields”.
Abstract: Each member of an ensemble simulation shows a possible occurrence of one or several physical fields, and domain experts are concerned with analyzing the uncertainty that is represented by these fields. Due to the sheer volume of such ensembles, their inherent spatial and temporal aspects, as well as the complex spatio-temporal relations between features in these fields, classical data mining and statistical analysis techniques become increasingly limited. While simple analysis tasks, like finding commonalities or differences at fixed locations in space and time, can be realized in an automated way, a meaningful and intuitive depiction of the uncertainty that is carried by an ensemble is challenging. When directional quantities and spatio-temporal relations between ensemble members have to be analyzed, the limitations of available techniques become even more severe and new approaches are required. In this talk I will shed light on the relation between ensemble and uncertainty visualization, and I will discuss a variety of visualization techniques for scalar- and vector-valued ensemble fields. This is followed by a summary of current and future challenges in ensemble visualization.
We are looking forward to hearing this exciting keynote by Rüdiger in Brno!

By popular demand, we have decided to extend the submission deadline to March 12th.
The updated dates are now:

• Paper Submission Deadline: extended to March 12th, 2018 
• Acceptance Notification: April 10th, 2018
• Camera-ready Deadline: April 20th, 2018

We look forward to receiving your submissions!

We are very happy to announce that EuroRV³, the international EuroVis Workshop on Reproducibility, Verification, and Validation in Visualization will continue in 2018. The sixth edition will be co-located with EuroVis 2018 in Brno, Czech Republic, and take place on June 4th, 2018.
We will soon publish a call for contributions, so stay tuned and please visit our website EuroRVVV.org.
