Tobii Pro screen based eye tracking devices

Screen-based eye tracking

Screen-based Tobii Pro eye tracking systems (Nano, Fusion and Spectrum) are designed to analyze the visual response to stimuli displayed on a screen.

Tobii Pro screen-based eye tracking

Powerful screen-based eye tracking systems that capture and analyze gaze data in response to screen-based stimuli. This family includes Tobii Pro Nano, Tobii Pro Fusion, and Tobii Pro Spectrum devices, which features sample rates of 60 to 1200 Hz. These devices have been developed to obtain objective data of human visual behavior evoked by the stimuli displayed on the screen, ensuring outstanding robustness and accuracy.

Tobii Pro is a world leader in advanced eye tracking technology. Combine this with Bitbrain devices, including EEG and biometrics, to obtain deeper insights into human behavior.

Bitbrain sells Tobii Pro eye tracking systems in conjunction with our own compatible neurotechnology systems.
