The Eyelink Toolbox software supports the measurement of eye movements by providing an interface between a high-level interpreted language (MATLAB), a visual display programming toolbox (Psychophysics Toolbox) and a video-based eyetracker (SR Research-Eyelink© Gazetracker). The Eyelink Toolbox enables experimenters to measure eye movements while simultaneously executing the stimulus presentation routines provided by the Psychophysics Toolbox.
The interface is implemented as a MEX file (EYELINK.mex), and a collection of m-files (native MATLAB code) The EyelinkToolbox uses the same approach as the SCREEN mex function provided in the PsychToolBox (which was used as example) and also uses the functions provided by this toolbox for doing any graphics involved (so you need to install the PsychToolBox for the EyelinkToolbox to function properly).
We greatly appreciate the
effort David Brainard and Denis Pelli have undertaken in making
the PsychToolBox. We further
want to acknowledge the contributions of Jos van der Geest and
Maarten Frens who started a similar project and who's experience
we have used in developing this implementation. Development of
the EyelinkToolbox was co-supported by RUG,
NWO-Inzicht and SR Research.
The EyelinkToolbox is described in a paper published by Behavior Research Methods, Instruments & Computers and is available in pdf format.
We would appreciate it if you would cite the Eyelink Toolbox paper when you have used the toolbox in your work. Do not forget to also cite Denis Pelli and David Brainard, the authors of the PsychToolbox (on which the EyelinkToolbox relies for its graphics).
So, you could write something like:
We wrote our experiments in Matlab, using the Psychophysics and Eyelink Toolbox extensions (Brainard, 1997; Pelli, 1997; Cornelissen, Peters & Palmer, 2002; see http://psychtoolbox.org/).

We cannot be hold responsible
for any damage that may (appear to) be caused by the use of this
toolbox. Use at your own risc.
