- 2. Introduction • We introduce a novel web-based open-sourced visual eye tracking analytics toolkit that can be directly incorporated into analysts' workflow. • Unified, flexible visual toolkit for gaze analytics 2
- 3. Motivation • Flexible analysis need • Absence of a unified, web-based visual eye-tracking analytics toolkit that combines multiple analytical features in one toolkit • Communication of insights 3

- 5. Gazealytics Overview • Gazealytics is an open-source toolkit: https://github.com/gazealytics/gazealytics-master • Live instance: https://www2.visus.uni-stuttgart.de/gazealytics/ • Get your tsv files ready and start exploring your gaze data!! 5
- 6. Key Features of Gazealytics • Flexible visual exploratory analysis • fully supporting Brehmer and Munzner's 11 visualization task typology • Multi-way visual exploration with matrix-based overview • Grouping and aggregate analysis • Group level visual exploration and comparison • Implemented in p5.js with a MVC framework 6
- 7. Flexible Visual Exploration 1: Import data (import) • Gaze samples (t, x, y) • Reference image 2: Overview with histograms, inspect raw gaze sequence, make sense of fixation filtering 3: Scanpath analysis with visual metrics 7
- 8. How Gazealytics Works - Flexible visual exploration 1: Import data: Gaze samples (t, x, y), image context 8
- 9. How Gazealytics Works - Flexible visual exploration 2: Overview with histograms, inspect raw gaze sequence, make sense of fixation filtering 9
- 10. How Gazealytics Works - Flexible visual exploration 3: Scanpath analysis with visual metrics 10
- 11. Multi-way visual exploration with matrix- based overview 1: Import data (import) • TWIs (TOIs) 2: Annotation of AOIs 3: Multi-way visual exploration with matrix- based overview (filter, select, aggregate, change) 11
- 12. How Gazealytics Works - Multi-way visual exploration with matrix-based overview 1: Import TWIs (TOIs) 12
- 13. How Gazealytics Works - Multi-way visual exploration with matrix-based overview 2: Annotation of AOIs 13
- 14. How Gazealytics Works - Multi-way visual exploration with matrix-based overview 3: Multi- way visual explorati on with matrix- based overview (filter, select, aggregate, change) 14
- 15. How Gazealytics Works - Interactive visual grouping and exploration in multiple data dimensions • 1: import more samples • 2: data-driven group correction • 3: group-level comparison 15
- 16. Example Walkthrough -hypothesis verification 16 Perceptually complementary [Chang et al. 2017]
- 18. Example Walkthrough - interactive annotation of AOIs RQ: what is the gaze allocation to the 3-by- 3 replicated layout? 18
- 19. Conclusion & Future Work • Takeaway • Flexible and unified visual toolkit • Multi-way visual exploration with matrix-based overview • Group and aggregate analysis • Example walkthrough • Open-sourced: Live instance: https://www2.visus.uni-stuttgart.de/gazealytics/ • We are recruiting participants for evaluating in their existing workflow. • Future work • User evaluation (submitted under peer review) • Flexible and unified gaze analysis for 3D immersive environment • integration into interactive visualization systems for real-time analysis of reading strategies 19
