Pupillometry
A guided 68-second camera experiment for observing relative pupil changes during attention and screen-light tasks.

Camera permission is required.
Measure the measurement.
Upload an eye image, click the pupil center, then mark its left, right, top and bottom edges to draw a reference ellipse. Compare it with the current boundary estimator. Images stay in this browser tab.
For accurate comparisons, upload a close-up of one eye. Processing uses a maximum 480 px image dimension. Results are in resized pixels, not millimeters.
No image selected. Start with a photo from your camera or image library.
Open-source detector comparison
Import image-level CSV or JSON results produced separately by EllSeg, PupilEXT/PuRe, Pupil Labs, or another detector. An independent threshold baseline runs in the browser; named third-party models still require external execution. Columns: image, detector, cx, cy, diameter, width, height. Image coordinates must use the same resized pixel dimensions as the saved reference; mismatches are excluded.

Exploratory assisted-boundary benchmark. Four-point ellipses are not independent clinical ground truth. No video analysis or automatic image upload is performed. Reloading clears the comparison set.
