Pupil Labs
Drug-free neurostimulation devices built to reset a nervous system stuck in fight-or-flight — engineered for the clinicians who trust the science.

Eye movements are the nervous system's most accessible output. Saccades, fixations, smooth pursuit, pupil dynamics — every one is a window into cerebellar function, frontal lobe integrity, vestibular processing, and attentional control. But until recently, capturing this data outside a lab required equipment that cost more than most clinical practices could justify.
Pupil Labs changed that. Their research-grade mobile eye tracking platform delivers 200 Hz binocular tracking, pupillometry, fixation mapping, and gaze analysis in a lightweight, wearable form factor — backed by over 3,800 peer-reviewed publications across neuroscience, cognitive psychology, and clinical medicine.
For CI scholars trained in oculomotor assessment, Pupil Labs transforms what you already know into quantifiable, reproducible data. Track saccadic latency changes through a treatment protocol. Document pursuit gain pre- and post-intervention. Map fixation patterns in patients with vestibular dysfunction. Pupil Labs brings the precision of a research laboratory into your clinical practice, with open-source software and open data formats that integrate with your existing workflows.

Questions clinicians ask first
Straight answers on how Hoolest devices work and who they're for.
Why mobile eye tracking vs. a fixed system?
Fixed systems restrict head movement and limit ecological validity. Pupil Labs' mobile glasses allow natural head movement during assessment, capturing how the oculomotor system actually behaves in real-world conditions — critical for functional neurology applications where compensatory strategies are part of the clinical picture.
How does it integrate with clinical assessments?
The open-source Pupil Player software provides real-time gaze streaming and post-hoc analysis including fixation detection, saccade identification, pupillometry, and dynamic area-of-interest mapping. Data exports in standard formats for integration with your reporting and documentation workflows.
Is this suitable for a clinical practice, or only research labs?
Both. Over 2,000 investigators use Pupil Labs in research settings, but the platform is increasingly adopted in clinical environments for oculomotor assessment, concussion evaluation, vestibular testing, and neurodegenerative screening. The wearable form factor and cloud-based analysis make it practical for daily clinical use.
What about training and support?
Pupil Labs provides documentation, a developer Discord community, and a team of PhDs and engineers available for custom workflow development. Their expertise spans vision science, deep learning, and clinical eye tracking applications.
