5 Overview of Tobii Pro Spark
Tobii Pro Spark is a compact, high-performance data collection solution that you can take into the
field. Use Tobii Pro Spark when your research takes you to locations and to subjects that would
otherwise be hard to bring to the lab. You can collect data in classrooms, hospitals, libraries, and
other locations where your subjects are easier to recruit.
With sampling frequencies of up to 60 Hz, one eye tracking camera, and two pupil tracking modes
(bright and dark pupil), Tobii Pro Spark enables you to adapt your data collection setup to dif-
ferent research populations and scenarios.
Use Tobii Pro Spark for studies on:
Windows, macOS, and Linux laptop and desktop computers
l
27" (16:9) monitors or smaller
l
Real-world setups such as physical objects and social interactions (using the Tripod Stand)

Tobii Pro Spark is primarily designed for use in indoor office environments with adult participants.
5.1 Tobii Pro Spark versions
Tobii Pro Spark is available in only one product version: 60 Hz.
5.2 How Tobii Pro Spark works
During tracking, Tobii eye trackers use infrared illuminators to generate reflection patterns on the
corneas of the participant's eyes. These reflection patterns, together with other visual data about
the participant, are collected by image sensors. Sophisticated image processing algorithms
identify relevant features, including the eyes and the corneal reflection patterns.
Tobii Pro Spark is a mono camera system that cycles between dark and bright pupil tracking.
Complex mathematics is used to calculate the 3D position of each eyeball along with the gaze
point (where the participant is looking).
