Surveys tell you what people say. Clicks show what they select. Eye tracking shows where they look, for how long, and in what order. Cost and complexity can still put dedicated eye tracking out of reach for many researchers, educators, and UX teams. Tobii Pro Spark lowers that barrier.

Screen recordings miss the gaze
A participant who scrolled past your CTA may have seen it and rejected it, or never noticed it at all. Click data and scroll maps can't distinguish these two fundamentally different behaviors.
When precision matters
Webcam eye tracking offers accessible visual attention insights at scale. For finer spatial accuracy, Tobii Pro Spark delivers dedicated eye tracking with 0.45° gaze accuracy in optimal conditions for fixation-focused measurement.
Research-grade data, made easy
Tobii Pro Spark uses dedicated infrared illumination and embedded eye-tracking processing, providing finer spatial accuracy and pupil-diameter data without relying on a participant’s webcam for gaze estimation.
At 60 Hz, it's purpose-built for fixation-based studies: where people look, how long they look, and what captures their attention.
Works across all participants
Reliable tracking regardless of age, ethnicity, or corrective lenses. Capture consistent data across children, older adults, and diverse participant populations.
Natural head movement
Participants move naturally at 65–80cm distance. No chin rest, no rigid positioning — especially important for usability studies and classroom research.
Optimized for varied lighting
Bright and dark pupil illumination delivers consistent data in controlled labs, office lighting, classrooms, and even museum exhibition settings.
Research-grade eye tracking
Unlike webcam-based trackers, Tobii Pro Spark uses dedicated infrared light and on-device processing for reliable eye tracking without relying on the cloud.
Tobii Pro Spark brings high-quality eye tracking within reach for educators, researchers, and UX professionals alike.
Used by innovative research and industry leaders including universities, design labs, healthcare, and usability teams around the world.
Used across classrooms, usability labs, accessibility studies, and other screen-based research settings.
Powered by Tobii’s patented 3D eye model technology, delivering reliable tracking performance across diverse users and research conditions.

Tobii Pro Spark focuses on what matters for fixation-based research: calibrated gaze and pupil-diameter data, reliable participant tracking, and a simple research setup. One camera, one cable, one EyeChip — a focused design for fixation-based studies
:quality(50))
Patented 3D eye model
Generates calibrated gaze coordinates and pupil diameter data from a 3D reconstruction of the eye.
Single-camera
One Tobii EyeSensor captures both eyes at 60 images per second for fixation and pupil-diameter measurement.
On-device processing
All gaze computation happens on a dedicated Tobii EyeChip™ ASIC inside the tracker, not on your computer's CPU.
One USB cable
Connect via USB-A (adapter to USB-C included). It runs from supported laptop or computer. No power supply, no external box, no ethernet.
Flexible stimulus setups
Study digital and physical stimuli using screens up to 27", mobile devices, or a tripod setup.
Tobii Pro Lab gives you a complete research workflow: design stimulus presentations (images, video, websites, screen recordings), run calibrated recording sessions, then analyze with built-in fixation filters, heat maps, gaze plots, and AOI metrics. Export data for further analysis in R, Python, MATLAB, SPSS, Excel, or your preferred toolchain.
