Abstract Eye tracking provides a unique perspective on the inherently visual discourse between visualisation systems and their users, has recently become sufficiently precise affordable to be integrated as regular input into workstations virtual or augmented reality headsets alike. As such, real‐time eye can now contribute significantly towards development of gaze‐aware visualisations that infer monitor users' needs actively support activities. To facilitate such we make three contributions....

We present an exploratory study on the accessibility of images in publications when viewed with color vision deficiencies (CVDs). The is based 1,710 sampled from a visualization dataset (VIS30K) over five years. simulated four CVDs each image. First, researchers (one CVD) identified existing issues and helpful aspects subset images. Based resulting labels, 200 crowdworkers provided 30,000 ratings CVD analyzed this data for correlations, clusters, trends, free text comments to gain first...

Abstract Adaptive visualization and interfaces pervade our everyday tasks to improve interaction from the point of view user performance experience. This approach allows using several inputs, whether physiological, behavioral, qualitative, or multimodal combinations, enhance interaction. Due multitude approaches, we outline current research trends inputs used adapt visualizations interfaces. Moreover, discuss methodological approaches in mixed reality, physiological computing, visual...

Visual analytics (VA) research provides helpful solutions for interactive visual data analysis when exploring large and complex datasets. Due to recent advances in eye tracking technology, promising opportunities arise extend these traditional VA approaches. Therefore, we discuss foundations support systems. We first review the structure range of typical Based on a widely used model, present five comprehensive examples that cover wide usage scenarios. Then, demonstrate model can be...

Visualization in virtual 3D environments can provide a natural way for users to explore data. Often, arm and short head movements are required interaction augmented reality, which be tiring strenuous though. In an effort toward more user-friendly interaction, we developed prototype that allows manipulate objects using combination of eye gaze external clicker device. Using this prototype, performed user study comparing four different input methods plus was preferred by most participants.

Conventional dot plots use a constant size and are typically applied to show the frequency distribution of small data sets. Unfortunately, they not designed for high dynamic range frequencies. We address this problem by introducing nonlinear plots. Adopting idea scaling from logarithmic bar charts, our allow dots varying so that columns with large number samples reduced in height. For construction these diagrams, we introduce an efficient two-way sweep algorithm leads dense symmetrical...

Gaze tracking in 3D has the potential to improve interaction with objects and visualizations augmented reality. However, previous research showed that subjective perception of distance varies between real virtual surroundings. We wanted determine whether objectively measured gaze depth through eye also exhibits differences entirely environments. To this end, we conducted an experiment (N = 25) which used Microsoft HoloLens a binocular add-on from Pupil Labs. Participants performed task...

Visualizing time series data with a spatial context is problem that appears more and often, since small lightweight GPS devices allow us to enrich the position information. One example visualization of energy output power plants. We present web-based application aims provide information about production specified region, along location The intended be used as solid basis for political discussions, nudging, story telling German transition renewables, called "Energiewende". It was therefore...

The analysis of eye-tracking data can be very useful when evaluating controlled user studies. To support the in a fast and easy fashion, we have developed web-based framework for visual inspection comparison scanpaths based on filtering fixations similarity measures. Concerning first part, introduce multiscale aggregation saccades spatial partitioning that reduces clutter overlaid without changing overall impression large-scale eye movements. technique abstracts individual allows an analyst...

We propose a new technique for visual analytics and annotation of long-term pervasive eye tracking data which combined analysis gaze egocentric video is necessary. Our approach enables two important tasks such hour-long videos from individual participants: (1) efficient (2) direct interpretation the results. Exemplary time spans can be selected by user are then used as query that initiates fuzzy search similar based on features. In an iterative refinement loop, interface provides suggestions...

Scatter plots are popular for displaying 2D data, but in practice, many data sets have more than two dimensions. For the analysis of such multivariate it is often necessary to switch between scatter different dimension pairs, e.g., a plot matrix (SPLOM). Alternative approaches include "grand tour" an overview entire set or creating artificial axes from dimensionality reduction (DR). A cross-cutting concern all techniques ability viewers find correspondence points views. Previous work...
