Tobii Pro Spectrum

Tobii Pro Spectrum/スペクトラム

This high-performance research system captures gaze data at speeds up to 1200 Hz. A screen-based eye tracker for extensive research from fixation-based studies to micro-saccades.

Overview

TobiiPro-Spectrum-reading-research-2_1.jpg

Tobii Pro Spectrum is our most advanced eye tracking platform, designed for extensive studies into human behavior and the mechanics of the fastest eye movements such as saccades, tremors, and micro-saccades. The system can capture data in high sampling frequency, while still allowing for natural head movement.

High performance for extensive behavior research

Tobii-pro-Spectrum-Eye-tracking-test-with-an-infant-in-front-of-Tobii-Pro-Spectrum-X-mode.jpg

Tobii Pro Spectrum provides exceptional flexibility, accommodating a wide array of research scenarios and study designs. This system can be used with the provided screen or with just the eye tracker, enabling both on-screen and real-world stimuli, such as physical objects or people. 

Flexible set-up options

TobiiProSpectrumwithBrainProducts.png

Multiple sampling rate options accommodate everything from fixation-based research to studies with more intense requirements on data granularity and time-based measurements. 
 
The 8-bit TTL port and precise timing enable seamless synchronization capabilities with external biometric data sources such as EEG, GSR, or ECG, providing a holistic view of behavior. 

Precise synchronization

Reading-research-with-TobiiPro-Spectrum-eye-tracker.jpg

Tobii Pro Spectrum tolerates larger and faster head movements than any other high-frequency screen-based eye tracker on the market. Tracking also resumes quickly if the subject moves in and out of the track box. With its ability to track freely moving subjects, Tobii Pro Spectrum greatly facilitates research with children.  

Unmatched freedom of movement

Features

Tobii’s patented 3D eye model delivers high-caliber gaze data 

Two eye tracking cameras, taking up to 1200 images per second  

Bright and dark pupil illuminators offer superior data regardless of eye shapes, ethnicity or age 

Detects eyes instantly with minimal data loss during blinks or looking away 

Allows precise synchronization of gaze information with other data sources 

Captures pupil data at the same sampling rate as the gaze data 

Provides eye images to understand what affects the data 

Maintains tracking robustness in different lighting environments 

Tobii Pro Spectrum is extremely accurate and precise with unparalleled tracking robustness, which makes it possible to study a very large portion of the population in many real-life conditions.

Components

Tobii-Spectrum-eye-tracker-component.jpg

The eye tracker unit can be used together with the provided monitor, or it can be used alone with other screens or real-world stimuli.

Eye tracker unit

TobiiPro-Spectrum-side-bottom-up-2_1.jpg

The removable high-resolution 24" monitor accommodates the display of on-screen stimuli. A low and stable response time of less than five milliseconds makes it suitable for studies where control of the timing of the stimuli presentation is essential. The IPS panel has a 178-degree viewing angle.
