AOI Rivers for Visualizing Dynamic Eye Gaze Frequencies
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
It is difficult to explore and analyze eye gaze trajectories for commonly applied visual task solution strategies because such data shows complex spatio-temporal structure. In particular, the traditional eye gaze plots of ...
The Aesthetics of Rapidly-Exploring Random Trees
(ACM, 2013)
Rapidly-Exploring Random Trees (RRTs) have been introduced as an algorithmic concept for the rapid exploration of configuration spaces targeting fast path planning, mainly applied in the field of robotics. Typically, such ...
Video Visualization for Snooker Skill Training
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
We present a feasibility study on using video visualization to aid snooker skill training. By involving the coaches and players in the loop of intelligent reasoning, our approach addresses the difficulties of automated ...
Scale-Stack Bar Charts
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
It is difficult to create appropriate bar charts for data that cover large value ranges. The usual approach for these cases employs a logarithmic scale, which, however, suffers from issues inherent to its non-linear mapping: ...
Evaluation of Attention-Guiding Video Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We investigate four different variants of attention-guiding video visualization techniques that aim to help users distribute their attention equally among potential objects of interest: bounding box visualization, ...
Visualization Showcase: General-Relativistic Black Hole Visualization
(The Eurographics Association, 2015)
Black holes are among the most fascinating and weird objects in the universe. They distort space and time in their close neighborhood in a way that is far beyond our every day experience. We demonstrate the visual effects ...
Efficient Parallel Vectors Feature Extraction from Higher-Order Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
The parallel vectors (PV) operator is a feature extraction approach for defining line-type features such as creases (ridges and valleys) in scalar fields, as well as separation, attachment, and vortex core lines in vector ...
Magnetic Flux Topology of 2D Point Dipoles
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Magnetic fields exhibit higher-order, nonlinear singularities in the form of point-dipole singularities. In addition, due to absence of divergence, they feature only a subset of invariant structures from traditional vector ...
Anaglyph Stereo Without Ghosting
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Anaglyph stereo provides a low-budget solution to viewing stereoscopic images. However, it may suffer from ghosting and bad color reproduction. Here we address the first issue. We present a novel technique to perceptually ...
Frayed cell diagrams
(ACM, 2014)
Tesselation-based or area-based visual representations are common to many artistic or visualization applications. For example, Voronoi art uses a space-filling tessellation of the image by Voronoi cells. We present frayed ...
