Tobii Pro Spark

Spark your research with our smallest and most affordable eye tracker. By capturing high-quality fixation data at 60hz, our entry-level eye tracker illuminates attention and intent.

Using Tobii Pro Spark in 3 easy steps

Connect

Tobii Pro Spark is designed for quick and easy setup! Attach to any screen up to 27”, or place it on a tripod for studies of real-world stimuli. Simply connect to the computer via USB.

Capture

Start recording high-quality attention data. Robust tracking means minimal data loss and reliable results regardless of corrective lenses, age, or ethnicity.

Understand

Tobii Pro Spark works with our software, supporting researchers from experiment design to data analysis. Eye tracking metrics and visualizations help you understand participants’ visual attention and behavior on a deeper level.

Technical specifications

Eye tracking specifications

Eye tracking technique	Video-based pupil and corneal reflection eye tracking with dark and bright pupil illumination modes. One camera captures images of both eyes for accurate measurement of eye gaze and eye position in 3D space, as well as pupil diameter.
Eye tracking mode	N/A (default)
Sampling frequency	60 Hz (default) or 33 Hz
Precision	0.26° RMS in optimal conditions (using built in filtering)
Accuracy	0.45° in optimal conditions
Binocular eye tracking	Yes
Eye tracker latency	1 frame (immediate)
Blink recovery time	1 frame (immediate)
Gaze recovery time	50 ms
Data sample output	Timestamp Gaze origin Gaze point Pupil diameter
Eye openness data stream	Not available
Eye image data stream	Not available
TTL input stream	Not available
Tracker and client time synchronization	Integrated between the eye tracker time domain and the client computer time domain.
User calibration	Binocular

Setup

Head movement tolerance	Good. One-camera system provides an accurate calculation of the data and a good level of precision. More sensitive for head movement than the dual camera systems.
Operating distance (mounted on screen)	45 cm to 95 cm (18’’ to 37”) from the eye tracker
Freedom of head movement (width x height)	Freedom of head movement at 50 cm distance 20 cm x 20 cm (7.9’’ x 7.9’’) (At least one eye tracked) Freedom of head movement at 65 to 80 cm distance 35 cm x 35 cm (13.8’’ x 13.8’’) (At least one eye tracked)
Optimal screen size	Up to 27″ (16:9 aspect ratio)
Recommended monitor	N/A
Tracker setup options	Eye tracker mounted on a tripod, allows for even larger screens or physical objects to be tracked. The Mobile Testing Accessory enables research or usability tests on a mobile device.
Participant setup	Very simple and easy. Typically, less than 1 minute.
