AI pupil detection × lightweight hardware × full automation — breaking traditional limits in small-animal eye tracking.
Advanced AI precisely tracks pupil dynamics, overcoming noise from complex lighting, blinks, and large eye movements for accurate, reliable data.
Among the world's lightest mobile eye-tracking systems — head-mounted recorder weighs only 1 g with built-in infrared illumination for stable imaging in low light.
Beyond traditional head-fixation — suitable for freely-moving mice with minimal impact on natural exploratory behavior.
Head-fixed system records up to 1000 fps, capturing subtle eye movements with synchronized behavioral camera recording.
Universal TTL interface for I/O synchronization — compatible with optogenetics, two-photon, electrophysiology, fiber photometry, and other multimodal neural recording and modulation.
User-friendly design — 0.4 g ETU connector implanted on skull, easy attach/detach, reusable, and protected from cage damage.
100+ metrics including pupil diameter, position, area, movement speed, saccade count/amplitude/velocity/duration, and more.
Pupil position maps, diameter/area/velocity plots, heatmaps, group comparisons, event-related pupil curves — export to jpg/pdf/csv.
Mobile and fixed lines with independent hardware and software — mobile for freely moving paradigms, fixed for high-frame-rate head-fixed experiments.
Shared by Both Products
Both lines share AI pupil detection, synchronized eye and behavior recording, bilingual software, publication-grade export, and TTL multimodal integration — choose mobile or fixed by paradigm.

From AI pupil extraction and multidimensional visualization to event-related analysis, oculomotor behavior, and multimodal integration.
Covers the full pipeline from eye-tracking video recording through annotation and model training to pupil detection. Deep learning delivers stable pupil coordinates under complex lighting, blinks, and head movement.
Transforms raw tracking data into interpretable statistics and charts — time series, spatial distributions, and population summaries for rapid group comparisons.
Aligns pupil diameter, area, and related parameters to experimental events to reveal arousal, stress, learning, or pharmacological pupil response patterns.
Combines threshold algorithms and deep learning to automatically detect blinks and other ocular behaviors with timestamps and frequency statistics.
Eye-tracking data syncs with freely moving, looming threat, and visual stimulation paradigms plus electrophysiology and optogenetics for comprehensive phenotyping.
In neuroscience, psychology, and psychiatry, monitoring eye information via eye tracking is a standard and essential measurement.
Eye tracking applies across paradigms from basic neural mechanisms to clinical translation.
Typical directions include:
Pupil-related arousal broadly influences behavior and brain state — pupil size is commonly used to study animal arousal.
This study examined mouse responses to TMT (trimethylthiazoline) exposure during REM sleep and effects on vigilance. Pupil size as a vigilance index increases with enhanced adaptive threat response.
Brief flash tests in wild-type dogs show pupil constriction. Mutant dogs exhibit prolonged pupillary light reflex latency and longer time to minimum pupil diameter.
Assessed pupil area responses in disease model mice under pharmacological intervention, comparing controls and disease models.
In Hit and FA trials, mice licked with large pupil dilation; in CR trials, correct NoGo responses without licking showed distinct pupil dynamics. Pupil dynamics became more pronounced with learning.
Eye-tracking parsed spontaneous and evoked saccades in head-fixed mice, revealing superior colliculus regulation.
In Alzheimer's, Parkinson's, and other neurodegenerative diseases, pupil diameter changes may serve as biomarkers.
Mobile and fixed mouse eye-tracking systems support high-impact papers in neural mechanisms, autism, sleep, visual escape, and more.
