 +
 +
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

Here is a '''tutorial video''' on how to '''setup Eyelink with a participant''': [https://www.youtube.com/watch?v=O3z8I5y_l5E&list=PLOdF-B36TwspxRQeam0u5Yd29wOjUWcel&index=7 Eyelink setup and calibration tutorial video.]
 +
 +
From the SR-Research support forum, about '''placement of monitor, camera and participant''':
 +
 +
''Ideally, the Desktop mount should be placed between 50-70 cm from the participant's eyes and be centrally aligned with the Display monitor from the participant's perspective. When using a wide screen monitor it will need to be sufficiently far away from the participant that it fits within the trackable range of the system. As a rule of thumb it will need to be at a distance at least 1.75 times its width (so a 40 cm wide monitor would need to be at least 70 cm away). As widescreen monitors are typically around 50 cm wide, they will need to be placed at least 90 cm away. This means that, in order for the camera to be placed correctly (50-70 cm from the participant's eyes) it will need to be brought forward from the monitor 20-30 cm.''
 +
 +
''The top of the EyeLink camera and illuminator should also be as high as possible in the participant's field of view without obstructing any part of the display.''

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.
