Affordable 500Hz Eye Tracking for Laboratory Research

Easy setup and robust tracking

LiveTrack Lightning supports monocular and binocular eye tracking at 500Hz. It's designed to be used with a simple chinrest, and easily copes with small head movements, so the participant remains relaxed and comfortable while producing robust, high quality data.

Dedicated processing: streams real-time data to your computer

Lightning connects to the LiveTrack Presto unit to generate the data; this is a compact embedded eye tracking system which interfaces to the stimulus computer by USB.

In real-time, Presto automatically identifies the dark pupil and corneal reflections in each eye, then calculates eye rotation and Direction of Gaze.

Video images, tracked eye position and pupil size data are transferred to the stimulus computer via a high-speed, low latency USB interface. This approach means no extra processing load on the stimulus computer and no complicated real time programming is required.

Live video of participant

The live video from the Lightning module is combined with the tracking data from the Presto unit, then the composite stream made available to view on the Presto HDMI and USB interfaces.

Get instant feedback to learn how the observer is performing by plugging a standard LCD monitor into the Presto HDMI output. The USB video output is provided in UVC format just like a webcam; it can be viewed with the LiveTrack host software tools and captured by a range of third-party utilities.

Very easy integration and synchronisation

LiveTrack Lightning is fully supported by EventIDE for real-time eye tracking analysis with detection and labelling of fixations and macro/micro-saccades.

The LiveTrack USB data interfaces are simple to integrate with MATLAB, Python and C on any computer regardless of the operating system; a simple API is provided to facilitate development of custom software. Also works with Presentation and ePrime and other third-party software. Plug&Play installation on Windows, MacOS or GNU/Linux with no proprietary drivers required. The Presto unit includes a full array of digital and analogue I/O to make it easy to trigger, synchronise and transfer the eye movement data to other equipment.
