What Pupil Core is

Pupil Core is a wearable eye-tracking headset paired with software for recording and analyzing gaze data in research. When connected to a desktop or laptop, Pupil Capture records and displays live gaze and pupil measurements. Pupil Player overlays gaze on first-person video, supports analysis plugins, and exports raw or enriched data. The system offers binocular or monocular tracking, five-point calibration, and dark-pupil tracking with a 3D model; its stated accuracy is 0.60° with calibration and precision is 0.02°. Two infrared eye cameras record at 192 × 192 pixels and 200 Hz. Scene-camera choices are 1080p at 30 Hz, 720p at 60 Hz, or 480p at 120 Hz. Users can extend the system with runtime-loaded Python plugins and connect other devices through its API, which can stream gaze data and scene video over a local network. It supports Windows, macOS, and Linux, and requires an Intel i7 or greater CPU and at least 8 GB RAM. Pupil Core costs €3,615.
