ABSTRACT
Eye tracking has become a well-studied field these days, not only because of the progress of the hardware technology and the reduced costs for eye tracking devices, but also due to the various application fields that benefit from it. Fields like neuroscience, cognition, human–computer interaction, medicine, sports, or the automobile industry all benefit from eye tracking, given the fact that the data is measured accurately and analyzed afterwards. The field of eye tracking has existed for many years but the technology as we know it today is not comparable with the early attempts to observe people’s eyes while they were solving a certain task. For eye tracking the eyes logically play an important role since they are obviously the core ingredient for this emerging technology. Eye tracking could even be useful to identify a disease of the eyes or even one that is not directly related to the eyes like Alzheimer’s.
