High performance for extensive behavior research
The Tobii Pro Spectrum is our latest and most advanced eye tracking platform, designed for extensive studies into human behavior and the mechanics of the fastest eye movements. While capturing data at speeds up to 600 Hz, it still allows for natural head movement, which opens up new possibilities in fields like psychology, developmental studies, neuroscience, reading research, and ophthalmology.
The Pro Spectrum is designed to ensure the highest data quality and reproducibility through evolving, patented eye tracking algorithms from Tobii, sophisticated hardware design, and premium hardware components.
Flexible set-up and sync options
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 both on-screen and real-world stimuli, such as physical objects or people. Multiple sampling rate options accommodate everything from fixation-based research to studies with more intense requirements on data granularity and time-based measurements.
The TTL port and precise timing enable seamless synchronization capabilities with external biometric data sources.
Unmatched freedom of movement
The Pro Spectrum tolerates more head movements than any other high-frequency screen-based eye tracker on the market. The system provides saccadic event resolution and extremely precise data.
This unique combination of capabilities allows researchers to deeply explore human behavior and cognitive processing, as well as the mechanics of the fastest eye movements (e.g. saccades, tremors, and micro-saccades), without interfering with the natural behavior of the subject. With its ability to track freely-moving subjects, the Pro Spectrum easily facilitates research with children and other participants who would otherwise need a chinrest to control their movement.
Data you can trust
The 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.
Simple ingenious design
The Pro Spectrum's simple setup, configuration, and automation allow you to add advanced eye tracking to your research with little effort. Researchers at all levels of expertise can use the system without needing training.
The eye tracker comes fully assembled in the supplied travel case and doesn't require manual configuration with the setup of cameras, lenses, etc. Researchers can rely on quick, stable calibration of subjects and productively track the subjects they have attained for their study.
“It is essential that eye trackers can tolerate head movement while providing high level eye tracking capacity to enable tasks that better reflect real-world scenarios. Fast processing eye tracking with freedom of head movement opens up new opportunities for innovative mental health research.”
Transparent product quality methods
The Pro Spectrum's high data quality standards have been confirmed through comprehensive testing and validation procedures, using well-documented test methods. Consistent reproducibility in studies is guaranteed with quality control procedures throughout the entire production process, including camera focus and the calibration of each unit. Multiple product certifications ensure that quality and user safety requirements are met.
Tobii Pro SDK
In the first quarter of 2017, there will be a new Tobii Pro SDK available for researchers who wish to develop niche applications or scripts to use with the Pro Spectrum and other screen-based eye trackers from Tobii Pro.
The Pro SDK will offer a broad set of tools to make it simple to develop a variety of applications across multiple platforms, using a wide range of programming languages. This SDK will give researchers access to the full set of eye movement data streams relevant to their research, such as 3-D eye coordinates, raw data, pupil data, etc.
Eye tracker unit
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.
This unit, without the monitor, measures 55 cm x 18 cm x 6 cm (22" x 7" x 2"). The eye tracker is mounted on a stand, which raises it from the surface with 9 cm (approx. 4").
The removable high-resolution 24" monitor accommodates the display of on-screen stimuli and has been carefully selected from a high-quality display manufacturer to meet the highest demands on stimuli presentation.
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, which ensures a consistent experience of the stimulus presented, independent of where the subject is positioned.
We recommend using this monitor, but optionally other monitors can be used too.
