Express Eye Tracker Software
This software is maintained at the 'Institute für Grenzgebiete
der Psychologie' in Freiburg i. Br., Germany. It may be licensed

What this software is
It is a communication interface between the Eye Express Tracker and the
Analyzer Software. To achieve communication, the software triggers the
eye tracker's lasers and records the received values. These values are
then stretched and normalized and supersampled. Then the sent laser values
are converted to the prior captured calibration values. These values may
then be exported along with the recorded values and imported into Analyzer.
The values may as well be written into a CSV file to import the values
into another spreadsheet tool like excel or SPSS. Unfortunately SPSS can
mostly work on a limited range of 3000 cases, which is not satisfying,
since 3000 values correspond to 6/5 seconds.
The data is supersampled at 2500 Hz to generate a constant datastream
and to not colide with Nyquist's Theorem.
What this software needs to run (Prerequisites)
A java compliant runtime environment: JDK 1.3.1 or higher
An Express Eye Tracker
