TRACKPixx3

2 kHz binocular eye tracker

The TRACKPixx3 is a 2 kHz eye/gaze-tracking solution. The TRACKPixx3 is versatile, supporting both monocular and binocular tracking with a single mechanical configuration. Interchangeable lenses support tracker distances from 60 cm to over 160 cm for fMRI applications. Add a low-cost secondary tracker to support remote head-free tracking. The TRACKPixx3 does not require a dedicated PC to process eye images and generate gaze information. All image processing is performed within the TRACKPixx3 hardware. Gaze data can be logged within the TRACKPixx3 and retrieved by the testing PC with a simple low-latency USB interface.

The TRACKPixx3 video feed can be accessed directly through a console display for real-time visualization and adjustment of the tracker. These video feeds can also be accessed through the USB interface for remote control of the TRACKPixx3.

Combine the PROPixx with the TRACKPixx3 2 kHz binocular eye tracker, and experience the simplicity of a single clock timebase for all your data!
