Tobii Pro Spectrum eye tracker synced with EEG

Psychology and Neuroscience

Eye tracking is used in various psychology and neuroscience fields to understand how and why eye movements are made and how we gather information visually.

Why use eye tracking in psychology and neuroscience?

Eye tracking is used in these fields of research to understand the connection between what we see and how we react based on the information we process.

Products and services

Tobii Pro offers eye tracking systems for psychology and neuroscience studies in a controlled research setting, such as a lab, as well as examining human behavior in real-world environments, like in an office or home. Analyzing data is made easier with our various software solutions and their ability to work with other companies' solutions.

Tobii Pro Spectrum

The Tobii Pro Spectrum offers up to a 1200 Hz sampling rate with high spatial and temporal precision and accuracy. It tolerates large head movements, which opens up possibilities for unobtrusive research of oculomotor functions with active subjects, such as children or atypical populations (e.g. those with autism spectrum disorder). The Pro Spectrum allows you to study eye movements and behaviors such as saccades, micro-saccades, tremor, fixations, scan paths, and pupil dilation.

The 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 the eye tracker alone, enabling research with both on-screen and real-world stimuli, such as physical objects or people.

Biometric synchronization

The TTL port and precise timing of Pro Spectrum enable seamless synchronization capabilities with external biometric data sources, providing a holistic view of behavior.

The combination of eye tracking and EEG enables the simultaneous examination of brain activity and eye movements. This provides researchers with information about regions of brain activation associated with cognitive or affective activities, such as visual search or the viewing of emotionally-charged imagery.

The Pro Spectrum works with Tobii Pro Lab, a versatile biometric software platform designed to meet the highest demands in different research scenarios with exact timing accuracy. This software supports the entire process - from test design and recording, to the interpretation and presentation of results while offering the ability to sync with other biometric data sources.

Stimuli can be shown on screen for as short as 50 milliseconds, making it suitable for research requiring very high precision in timing. When stimuli are presented, TTL signals are sent to sync the stimuli presentation and data recording with external research systems. This capability will allow researchers to ask more complex questions, for example, when adding eye tracking to their EEG research.

Tobii Pro SDK is available for researchers who wish to develop niche applications or scripts for use with the Pro Spectrum.

Eye tracking in reading behavior research

In this video, Dr. Simone C. Ehmig, from the German Reading Foundation (Stiftung Lesen) in Mainz, explains how wearable eye tracking technology enables her to better understand reading behavior of people exposed to enormous amount of information on different media channels. Tobii Pro Glasses 2 was used to study how young adults use written language in their everyday lives, including their reading, writing, media usage, and active participation in online media.

Driven by Caravaggio: eye tracking study reveals the artist’s intentions

Researchers at Scienza Nuova in Italy used eye tracking to test the hypothesis that Caravaggio understood how we perceive images and that he, while creating his art, took into account how the environment would affect the viewer’s visual experience.  Read more

Eye tracking used to compare tactile and visual reading strategies

Researchers from the Netherlands used Tobii Pro Glasses 2 and an infrared motion-capturing system in order to understand the reading strategies of both sighted and braille-dependent students when reading algebraic expressions.  Read more

Audi Attitudes

Audi's Attitudes, a corporate social responsibility program, wanted to learn more about the phenomenon of driving without awareness. Wearable eye trackers from Tobii Pro enabled their researchers to gain insight into driving behavior and occurrences that are often forgotten by drivers. The data revealed significant changes in gaze patterns during phases of subconscious driving and helped identify situations and external factors causing the issue. Read more
