ATP Eye Tracking Lab



We use an EyeLink II eyetracking system by SR Research Ltd./Canada. This system was developed by Eyal Reingold and Dave Stampe.

The EyeLink System performs real-time measurement of pupil position, pupil size, and marker positions acquired from headband-mounted high-speed cameras. It parses binocular eye movements into saccades, blinks, and fixations on the basis of user-adjustable parameters. The system is based on a miniature imaging sensor technology, which provides high temporal resolution of 2 or 4 milliseconds (500 or 250 samples per second) and high, spatial resolution of 0.01°.

PC-Hardware und Software

We use a DELL Pentium as host PC and a display PC with a 20'' monitor.

Data are presented on the monitor or are projected on a hardscreen.EyeLink Software is freeware and can be downloaded under (PsychToolbox) and (EyeLink Toolbox).We further use MatLab 5.2.1 and 6.5 (MathWorks). A description of the software and the toolboxes can be found in a paper by Cornelissen, Peters and Palmer (2002).
