After the details of the electrooculargram and seeing how difficult the results could be, this articular was a bit of a relief. Berger, Winkels, Lischke, and Höppner offer a program capable of analyzing the raw data of eye tracking in “GazeAlyze: A MATLAB toolbox for the analysis of eye movement data.” It was not any less detailed or methodical than the article about raw electrooculargraphy, but knowing that there is a program like GazeAlyze that works through MATLAB, a program available on a number of universities, including Alabama, made eye movement a more feasible experimental measure. This also opens up the possibility that researchers experienced in MATLAB would find the eye tracking data easy to read, or at least could become familiar with the analysis relatively easily.
Beyond my personal relief, the authors note a few improvements that would be convenient for researchers and improve on previous software such as ILAB. GazeAlyze allows files to be exported as images and marking of regions of importance (ROI). Although these features might be easier to use if the subjects look at static images while their eye movements are tracked, they also allow easier sharing and reproduction of results. In particular, compared to the raw data of eye movements, heat maps generated by the program would be more intuitive to understand.
