Reading with Screen Magnification: Eye Movement Analysis Using Compensated Gaze Tracks

Abstract

Figure 1: Left: Gaze points recorded from a reader with low vision using full screen magnification to read the text document shown (unmagnified) in the background (participant P1; magnification factor: 19.2). The reader moved the magnified screen with the mouse to bring the content of interest at each time within the screen viewport. Right: The same gaze points after compensation. Note that the compensated gaze points tend to follow the text lines. A careful observer may note clusters of compensated gaze points in the zoomed-in area, corresponding to compensated fixations.
