Quick View

Screen–based eye tracker capturing gaze data at 300 Hz. Plug–and–play attachment to a provided 23" monitor with optional stand–alone use. This proven, premium research system provides data of outstanding quality and is designed for exhaustive, detailed fixation and saccade–based studies.

Scientific-grade, outstanding for detailed research

The Tobii Pro TX300 collects gaze data at 300 Hz while allowing for large head movements. This unique capability, together with extremely–high accuracy and precision, as well as vast tracking robustness, extends the possibilities for unobtrusive research into human behavior and oculomotor functions. In both behavior and eye movement research involving children or primates, subjects can be positioned comfortably, without an unnatural chinrest. The system's premium components and superior data quality has established it as a trusted choice by many of the world's leading research institutions. The Pro TX300 captures data at 300, 120, or 60 Hz. This eye tracker shows exactly where people are looking and is designed for studies that require a higher sampling rate

Ultimate flexibility in setup and software

e.g. detailed research into minute eye movements such as saccades, correction saccades, fixations, pupil size changes, and blinks.


Eye tracker unit

The Pro TX300 includes the eye tracker unit and a removable 23" monitor. The system can be used with the provided screen or with just the eye tracking hardware alone. These two options enable both on–screen and real–world stimuli to be used. A wide range of software applications are compatible with the Pro TX300, including Tobii Pro Studio, E–Prime Extensions, and the Tobii Pro Analytics SDK, which includes free MATLAB and Python 2.7 bindings. The Pro TX300 also integrates with the StimTracker, providing a versatile solution to synchronize on–screen stimuli and eye tracking data with various physiological data. It reliably and accurately synchronizes on–screen stimuli, eye tracking data down to a single millisecond. The StimTracker enables you to connect your eye tracker to several leading biometric data collection systems, as well as a PC parallel port.

Monitor unit

The eye tracker unit can be used together with the provided monitor, or it can be used alone with other screens. For real–world stimuli setups, we include a desk stand for mounting the eye tracker separate from the monitor to fit your needs. A floor stand is offered as an accessory option, as well. The eye tracker unit without the monitor measures 55 x 24 x 6 cm (22 x 9 x 2") and weighs 6 kg (13.2 lbs.) excluding the desk stand.
