ATP Eye Tracking Lab

Eyetracker

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 an Apple imac under OS 9.2.2 or OS X 10.2.1 as display PC.

Data are presented on a 17'' monitor or are projected on a hardscreen.

EyeLink Software is freeware and can be downloaded under http://www.psychtoolbox.org/ (PsychToolbox) and http://cornelis.med.rug.nl/pub/eyelinktoolbox/ (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) and can be downloaded as a pdf.
