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.
Specifications
| EyeLink II |
|---|
| 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
http://www.sr-research.com/eyelink1000.html
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

|---|---|
| Sampling Rate | Head Supported: 2000 Hz Monocular / 1000 Hz Binocular
Remote / Head Free: 500 Hz Monocular |
| Accuracy | Head Supported: 0.25º -0.5º average accuracy
Remote / Head Free: 0.5º average accuracy |
| Real-time Data Access | Head Supported: 1.4 msec (SD < 0.4 msec) @ 2000 Hz
Remote / Head Free: 3 msec (SD < 1.2 msec) @ 500 Hz |
| Participant Setup | Very simple and easy. Typically less than 2-5 minutes |
| Resolution | Head Supported: 0.01º RMS, micro-saccade resolution of 0.05º
Remote / Head Free:0.05º RMS, saccade resolution of 0.25 |

Tobii
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 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.
