Welcome to the Workshop on Eye Tracking and Visualization
There is a growing interest in eye tracking as a research method in many communities, including information visualization, scientific visualization, visual analytics, but also in human-computer interaction,applied perception, psychology, cognitive science, security,and mixed reality. Progress in hardware technology and the reduction of costs for eye tracking devices have made this analysis technique accessible to a large population of researchers. Recording the observer’s gaze can reveal how dynamic graphical displays are visually accessed and which information are processed in real time. Nonetheless, standardized practices for technical implementations and data interpretation remain unresolved. With this third Workshop on Eye Tracking and Visualization (ETVIS), we intend to follow-up on the highly successful first and second ETVIS Workshops (at IEEE VIS 2015 and 2016) and continue to build a community of eye tracking researchers within the visualization community, covering information visualization, scientific visualization, and visual analytics. We also aim to establish connections to related fields, in particular, in human-computer interaction, cognitive science, and psychology. This will promote a robust exchange of established practices and innovative use scenarios.
Scope and Focus
Technological advances in computer vision algorithms and sensor hardware have greatly reduced the implementational and financial costs of eye tracking. Thus, it is unsurprising to witness a significant increase in its use as a research tool in fields beyond the traditional domains of biological vision, psychology, and neuroscience, in particular, in visualization and human-computer interaction research. One of the key challenges lies in the analysis, interaction, and visualization of complex spatio-temporal datasets of gaze behavior, which is further complicated by complementary datasets such as semantic labels, user interactions and/or accompanying physiological sensor recordings. Ultimately, the research objective is to allow eye tracking data to be effectively interpreted in terms of the observer’s decision-making and cognitive processes. To achieve this, it is necessary to draw upon our current understanding of gaze-behavior across various and related fields, from vision and cognition to visualization.
The technical and financial aspects of recording of eye movement data are not a big issue anymore—with low-cost eye tracking devices being widely available. We have seen a large increase in research and papers related to eye tracking. However, the analysis, interaction, and visualization of such gaze data—along with additionally attached data from the stimulus or further physiological sensor recordings—becomes a challenging factor in this emerging discipline. Also, from the human-computer interaction and the cognitive science perspective, many aspects have to be focused on integrating the human behavior and the decision-making and thinking processes. All together make eye tracking an important field to be understood, be it in the sense of data analysis and visualization, interaction, or user-based evaluation of visualization.
This workshop will cover topics that are related to visualization research (including information visualization, scientific visualization, and visual analytics) and eye tracking. Aspects discussed in this workshop include the following topics with an emphasis on the relationship between eye tracking and visualization:
- Visualization and visual analytics techniques for eye movement data

- Eye movement data provenance, big eye movement data
- Uncertainty visualization of gaze data
- Standardized metrics for evaluating interactions with visualization
- Novel methods for eye-tracking in challenging visualization scenarios
- Interactive annotation of gaze and stimulus data
- Systems for visual exploration of eye movement data
- Reports of eye tracking studies evaluating visualization or visual analytics
- Eye tracking in non-WIMP visualization environments, including mobile eye tracking, mobile devices, virtual environments, mixed reality, and large displays
- Eye tracking-based interaction techniques for visualization
- Interpreting eye movement scanpaths from the perspective of human cognitive architecture and perceptuo-motor expertise
- Perception in eye tracking studies
- Inferences that can be drawn from gaze behavior
