The EyeLink II has the fastest data rate and highest resolution of any head mounted video-based eye tracker. This exceptional data quality results in very low velocity noise, making the EyeLink II ideal for saccade analysis and smooth pursuit studies.
The EyeLink II system consists of three miniature cameras mounted on a comfortable padded headband. No mirrors are used in the EyeLink II system, making it very robust and easy to set up. Two eye cameras allow binocular eye tracking or easy selection of the subject’s dominant eye without any mechanical reconfiguration. An optical head –tracking camera integrated into the headband allows accurate tracking of the subject’s point of gaze without the need for a bit bar.
Key Features • 500 Hz binocular eye monitoring • 0.5° average accuracy • Access eye position data with 3.0 msec delay • 0.01° RMS solution • High quality computer based or scene camera eye tracking • Fast and simple participant setup, calibration, and validation
"The EyeLink II system is convenient to use, especially for vision researchers at an early stage of their study. However, before purchasing this system I would have preferred to have known if the system was comfortable for participants and details of the accuracy of calibrations. Altogether, I would recommend this system to other vision and cognitive researchers."
