Eye Tracker Data and Simulated Fixations

In the following, I am presenting the transparencies of my presentation "Eye Tracker Data and Simulated Fixations" within the turorial "Visualization of Eye Tracking Data" at the conference KogWis hosted by University of Tübingen. In recent years, the increased sophistication and accessibility of eye tracking technologies have generated a great deal of interest in using eye tracking data in a wide variety of disciplines. But do we need complicated devices and sophisticated measurements to track the regions people focus on? Is there not a way to identify fixations by means of simulation algorithms?
