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.

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

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.
