EyeLink II

The EyeLink II system consists of three miniature cameras mounted on a padded headband. Two eye cameras allow binocular eye tracking or selection of the subject’s dominant eye.

An optical head-tracking camera integrated into the headband allows accurate tracking of the subject’s point of gaze without the need for a bite bar.

500 Hz binocular eye monitoring
0.5º average accuracy
Access eye position data with 3.0 msec delay
0.01º RMS resolution
High quality computer based or scene camera eye tracking
Fast and simple participant setup, calibration, and validation

EyeLink 1000



The core of the EyeLink 1000 eye tracker consists of a custom designed high-speed camera connected to a dedicated Host computer. Running on a real-time operating system, the Host software provides extremely fast eye sample access with incredibly low inter-sample variability, accessed via a set of programming interfaces for multiple operating systems and programming languages

Tobii T60/T120

The Tobii T60 and T120 Eye Trackers are integrated into a 17" TFT monitor. They are ideal for all forms of eye tracking studies using screen based stimuli.

There is a Tobii setup in the babylab, which is in a fixed lab setup.

There are also two mobile Tobii setups. Please contact Gero Lange (mailto:g.lange@psych.ru.nl) for booking requests. Please keep in mind that these mobile setups are booked _without_ a room. If you plan to use these eyetrackers, make sure to also book a room that can be locked. You can use it in a cubicle, as long as you make sure that the eyetracker is stored in a locked room at the end of the day.
