This exceptional data quality results in very low-velocity noise, making the EyeLink II ideal for a wide range of eye-tracking research. The EyeLink II has Pupil + Corneal Reflection and Pupil only tracking modes. It has 500 Hz binocular eye-tracking, 0.5º average accuracy, and 0.01º resolution as well as access to eye position data with 3.0 msec delay.

Accessories for the EyeLink II
There are a number of accessories that you can bundle with the EyeLink II. If you would like further details, please contact our sales team at sales@sr-research.com, and they will be happy to answer any of your questions.
A forward-facing, head-mounted camera provides gaze position on video. The camera has 250 Hz sampling rate and excellent tolerance to external and varying light sources. Binocular recording is used to correct for horizontal and vertical parallax errors when the participant looks at non calibrated viewing distances.
The Black Box ToolKit Response Pad (left) and the Millikey Button Box (right) are both millisecond accurate. Each is recognized as a USB keyboard so can be used with any operating system or programming approach. Both have arcade-style buttons with clear caps that can be removed to place your own information beneath. The Black Box ToolKit Response Pad is available in two different 5 button layouts (W and V).
The Analog Output card is for research settings in which digital gaze data cannot be accessed over the ethernet link. It provides analog output of X and Y position data and pupil size. Data updates every sample (up to 2000 Hz). The card has a programmable range between +/- 10 volts and an analog breakout board with BNC connectors.
