The usability team of Wolfram Inc. visited our lab in summer 2007. I was required to think up a way to do eye-tracking for external software, such as the Mathematica product of Wolfram, with our EyeLink eye tracker by SR Research Inc.
Thinking of the importance of eye tracking in software and website usability study, I think it might help others to open source my solution.
Please browse the video in the right for the final effect.
The steps to do eye-tracking for Mathematica are:
Step 1: Create data file for eye-tracking in the host computer of Eyelink, and run , which is to keep on capture the display screen at fixed but easily adjustable frequency.
Step 2: Convert eye tracking data .edf to .asc with the EDF2ASC Converter by SR Research Inc.
Step 3: Extract fixation, time and other interested data out with
Step 4. Use
Step 5. Use
