Supported Eye-Tracker File Formats

GazePlotter visualizes gaze data uploaded from all major eye-tracking software: Tobii Pro Lab, SMI BeGaze, Gazepoint, Pupil Cloud, Varjo, OGAMA, and custom CSV files. Visualizations are built automatically from your eye-tracking data without any manual configuration or data transformation.

The workspace is designed to be easy to use and to provide a quick overview of the data and is available at gazeplotter.com.

On loading the workspace, you will see a demo data visualization. The demo data is a sample from the Tobii Pro Lab software, with fixations (and AOI hits), saccades, and EyesNotFound segments.

Import button

Click Import in the workspace to upload your own files. GazePlotter detects the file type automatically and builds the visualizations.

Supported file types

The workspace supports the following file types:

• Tobii Pro Lab
• OGAMA
• GazePoint
• SMI BeGaze
• Varjo XR
• Pupil Cloud
• Custom CSV

Workspace import

You can also select a GazePlotter workspace file to restore a saved session, which is useful for sharing analyses. A single .json file is always treated as a workspace import; workspaces saved with stimulus reference media are .gazeplotter.zip archives and import the same way.

Event files

Include event files (.xml, or .json alongside other files) in the same selection. GazePlotter detects them and prompts you to map them to stimuli and participants after the eye-tracking data is parsed. See Event Data for details.

Reference media files

Include image or video files in the same selection to attach them to stimuli as reference media, drawn behind gaze data in the Scanpath plot. A file attaches automatically when its name matches a stimulus’s original or displayed name, ignoring case. The name may match with or without its extension, so scene.png attaches to a stimulus named scene, scene.png, or scene.jpg. Each stimulus takes one file: when several files match the same stimulus, the first attaches and the rest join the unmatched files, which prompt for manual assignment. Media can also be uploaded on their own once eye-tracking data is loaded. Such an upload is one undoable step: if it replaces media a stimulus already had, the confirmation names that stimulus and Undo restores the previous file. Media can also be attached per stimulus in the Stimuli Library.

Starting over

There is no demo-reload button. To return to the demo data, reload the page; to replace the current data, import new files.
