We’re pleased to announce significant updates to Pupil Cloud.

Previously, Pupil Cloud visualized gaze, fixations, and blinks from Neon recordings. With this release, we’ve expanded visualizations to include additional data captured by the Companion Device: eye video overlays, eye aperture graphs, pupil diameter graphs, and audio graphs. These new tools help researchers explore, analyze, and annotate their eye-tracking data directly within Pupil Cloud.

Eye Video

Recordings now include synchronized playback of eye videos alongside the scene video. Eye videos can be repositioned, resized, and toggled on or off.

Please note that all recordings uploaded within the last 5 months will have eye video overlay available. Older recordings will have eye video available by 2025-07-15.

Data Tracks

We’ve added three new tracks to the timeline, enabling visualization of:

• Pupil diameter

• Eye aperture

• Audio

Hover or scrub the playhead to view exact values and min/max ranges. Zoom in to examine individual data points.

Track Customization

Users can toggle data tracks and video overlays on or off, and rearrange tracks to suit their workflow.

Playback Settings

Video player and timeline settings are now unified in a single menu. Adjust playback speed, toggle follow playhead, show or hide eye videos and graph values, and customize data tracks from one place.
