Accurate Real-time 3D Gaze Tracking Using a Lightweight Eyeball Calibration
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
3D gaze tracking from a single RGB camera is very challenging due to the lack of information in determining the accurate gaze target from a monocular RGB sequence. The eyes tend to occupy only a small portion of the video, ...
VisEvol: Visual Analytics to Support Hyperparameter Search through Evolutionary Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
During the training phase of machine learning (ML) models, it is usually necessary to configure several hyperparameters. This process is computationally intensive and requires an extensive search to infer the best ...
Visual Analysis of the Finite-Time Lyapunov Exponent
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
In this paper, we present an integrated visual analytics approach to support the parametrization and exploration of flow visualization based on the finite-time Lyapunov exponent. Such visualization of time-dependent flow ...
Extraction of Distinguished Hyperbolic Trajectories for 2D Time-Dependent Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
This paper does two main contributions to 2D time-dependent vector field topology. First, we present a technique for robust, accurate, and efficient extraction of distinguished hyperbolic trajectories (DHT), the generative ...
Visual Parameter Selection for Spatial Blind Source Separation
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Analysis of spatial multivariate data, i.e., measurements at irregularly-spaced locations, is a challenging topic in visualization and statistics alike. Such data are integral to many domains, e.g., indicators of valuable ...
A Grammar-Based Approach for Applying Visualization Taxonomies to Interaction Logs
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Researchers collect large amounts of user interaction data with the goal of mapping user's workflows and behaviors to their high-level motivations, intuitions, and goals. Although the visual analytics community has proposed ...
Shape-Guided Mixed Metro Map Layout
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Metro or transit maps, are schematic representations of transit networks to facilitate effective route-finding. These maps are often advertised on a web page or pamphlet highlighting routes from source to destination ...
Eye-Tracking-Based Prediction of User Experience in VR Locomotion Using Machine Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
VR locomotion is one of the most important design features of VR applications and is widely studied. When evaluating locomotion techniques, user experience is usually the first consideration, as it provides direct insights ...
