Creating information visualization tools is a challenging task for which expertise in many research fields is required to get a suitable result for the tasks at hand, for example, to interactively explore data sets for data patterns. To reach a good ...

Visual exploration of large and complex data is becoming increasingly important in different domains. However, non-experts in the field of visual data analysis often have problems with correctly reading and interpreting information from visualization ...

Multi-view visualizations are typically presented in a grid layout with elements positioned according to their bounding rectangles. These rectangles often contain unused white space. In cases where Tufte’s Shrink Principle can be applied to reduce non-...

Color is one of the fundamental elements of paintings. This paper proposes a set of measurements for color usage in a painting, including basic color elements, color harmony templates, and spatial distribution, characterizing both global and local ...

The attention mechanism in artificial neural networks is conceptually interlinked with human visual attention, and studies have shown that either artificial or human attention can facilitate computer vision tasks. However, little research has ...

To automate deformation that preserves mental images, an experiment was conducted to determine the conditions under which mental images are preserved using line simplification, a method of deformation. The experiment was conducted using prefectures in ...

We instrument Group Diagrams (GDs) to reduce clutter in sets of eye-tracking scanpaths. Group Diagrams consist of trajectory subsets that cover, or represent, the whole set of trajectories with respect to some distance measure and an adjustable ...

Data visualization relies on efficient rendering to allow users to interactively explore and understand their data. However, achieving interactive frame rates is often challenging, especially for high-resolution displays or large datasets. In computer ...

When visualizations are used to augment text, geographical information on a map, or on mobile devices, there often is not enough space to show complex data with approaches like juxtaposed visualizations or coordinated views. To alleviate this issue, we ...

Appropriate communication and understanding of political data are key to achieve a healthy dialogue between civil society and political institutions. This is particularly important for data generated by bodies that most directly represent citizens, such ...

Tumor tissue characteristics derived from imaging data are gaining importance in clinical research. Tumor sub-regions may play a critical role in defining tumor types and may hold essential information about tumor aggressiveness. Depending on the tumor’...

Earthquakes are one of the most destructive natural forces on Earth. Helping uncover and understand the hidden patterns behind the occurrence of Earthquakes is vital for preparation and emergency response. Unfortunately, it is difficult to do so as ...

Statistical graphs are becoming common in many fields. Modern authoring tools offer easy ways to create complex graphs. Despite multiple sources of advice, graph designers have little objective evidence on which to base design decisions to alleviate ...

Authoring situated visualizations in-situ is challenging due to the need of writing code in a mobile and highly dynamic fashion. To provide better support for that, we define requirements for text input methods that target situated visualization ...

We contribute MolecuSense, a virtual version of a physical molecule construction kit, based on visualization in Virtual Reality (VR) and interaction with force-feedback gloves. Targeting at chemistry education, our goal is to make virtual molecule ...

Geospatial planning drives the population-resource-environment system and guarantees sustainable development. In Switzerland, the development of vacancies can be observed in various municipalities. Hence, no optimal geospatial planning is taking place. ...

Based on the assumption that semantic relatedness between documents is reflected in the distribution of the vocabulary, topic models are a widely used class of techniques for text analysis tasks. The application of topic models results in concepts, the ...

In 2021, the University of Applied Sciences of the Grisons (FHGR) set the world record for the most accurate calculation of the circular number pi by calculating 62.8 trillion decimal places. The goal of the follow-up project described here is to ...

Search engines are ubiquitous in academic research and modern internet culture, but most only parse information into large blocks of text. This paper explores a visual search representation that encodes publication metadata in an inertial, interactive, ...

Humans are able to associate colors with certain objects. However, if the color is missing like in grayscale images it is questionable if such associations can be built the same way. To investigate this aspect we conducted an eye tracking study. We ...

This paper presents the possibilities to improve data monitoring in biosphere reserves. As a reference object, the monitoring system of the UNESCO Biosphere Entlebuch in Switzerland is examined and tested for options to optimize it. Biosphere reserves ...

The number π has motivated mathematicians and math enthusiasts for millennia. John Venn was one of the first to use visualizations with π. In this paper, we use visualizations to reveal patterns in the first 62.8 trillion digits of π. We computed the ...
