TRACKPixx3 MRI/MEG

MRI/MEG 2 kHz binocular eye tracker

Overview

The TRACKPixx3 MRI/MEG is a 2 kHz eye/gaze-tracking solution compatible with MRI and MEG environments. The TRACKPixx3 is versatile, supporting both monocular and binocular tracking with a single mechanical configuration. 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. A scene camera can be connected to the tracker to monitor the experiment. These video feeds can also be accessed through the USB interface for remote control of the TRACKPixx3.

An easy and fast option is also available to convert the TRACKPixx3 MRI / MEG to a low cost eye tracker tabletop configuration.

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