GazeAlyze is an open-source MATLAB software toolbox designed for the offline batch analysis of eye-tracking data. The tagline “See Exactly What Attracts Your Audience” highlights its core scientific and commercial value: tracking exactly what humans look at, what they ignore, and how their visual attention shifts.
Originally built to bridge the gap between complex raw data and actionable behavioral insights, it helps researchers and marketers map conscious and subconscious visual attention. What GazeAlyze Does
When people look at an image, an advertisement, or a user interface, eye-trackers record thousands of tiny data points per second. GazeAlyze takes this messy, raw tracking data and processes it through an automated pipeline:
Artifact Filtering: It cleans the data by removing eye blinks, signal noise, and errors caused by head movements.
Event Detection: It automatically segments data into fixations (where the eye pauses to look) and saccades (the rapid jumps between those pauses).
Region of Interest (ROI) Mapping: Users can define specific zones on a visual (like a logo, a product price, or a face) to calculate exactly how many people looked at it and for how long.
Batch Processing: Instead of analyzing participants one by one, it processes multiple data files simultaneously to speed up large audience studies. Visualizing the Audience Experience
To help teams see exactly what grabs attention, GazeAlyze generates data-driven visual layers:
Fixation Heat Maps: Color-coded overlays where red hot-spots reveal the exact elements that received the highest density of audience attention.
Path Plots (Scanpaths): Chronological, numbered lines tracking the precise sequence of how an audience reads or scans a design, highlighting whether they followed the intended visual hierarchy. Who Uses It and Why?
Because it is distributed free of charge under the GNU Public License, it is highly customizable. It is primarily utilized across three major landscapes:
UX/UI Designers: To ensure critical app features, dashboard analytics, or call-to-action buttons are intuitively placed and easily noticed by users.
Marketing & Advertising Researchers: To test print ads, social media posts, packaging, or store layouts before a major commercial launch.
Cognitive Scientists: To study human behavior, visual perception deficits, and involuntary cognitive processing.
To better understand how GazeAlyze fits into your project, could you share a bit more context?
Are you looking to use this for academic cognitive research or commercial UX/marketing optimization?
Do you need to track attention on static visual media (like websites and images) or dynamic media (like video and film)? Do you already have eye-tracking hardware, or
