SWIFT: A Dynamical Model of Saccade Generation During Reading
by Ralf Engbert, Antje Nuthmann, Eike Richter, and Reinhold Kliegl (2005),
Psychological Review 112, 777-813.


Simulation example:


The source code of the iteration loop given on this web page was used for all simulations in the paper.
How to use implement the model on a computer?

Step 1: Download and extract the archive file swift.tar.  Change directory to "SWIFT".
Step 2: Compile the program "swiftsim.c".  Using the GNU compiler with command line "gcc -o swiftsim swiftsim.c -lm".
Step 3: Start MATLAB.  Change directory to "SWIFT". Execute the program "xvisual.m".  Choose a sentence ID of the Potsdam Sentence Corpus (1 .. 144). 

Notes:
The executable file produced in "Step 2" above must be named "swiftsim", if you use the MATLAB visualization program.
