We tested the impact of diferently designed text on legibility. We used an eye trac- king device to observe the reading of people with dyslexia, while they read from an LCD display. We measured the reading time, observed the fxation duration and the number of positive and negative saccades. We also tested the reading compre- hension. Legibility was tested with eight texts, that difered in typographic design. The typefaces used for the tests were opensyslexic and open sans. The amount of space between characters and words also varied between texts, that formed our tests. The texts were designed in a way that enabled all variables to appear in com- bination with one another. The reading speed varied widely between participants. They read the texts, for whi- ch we used the open sans typeface faster, but the use of opendyslexic lead to better reading comprehension results. The content of texts, which generally proved to be too difcult, had a great impact on the reading times and the comprehension of the texts. The text with an enlarged space between words was on average the fastest read. The texts with enlarged space between words and characters were not read faster, they were read at a similar pace as the texts without enlarged spaces. The amount of regressions was the highest in the text with the slowest reading time and the lowest in the text with the shortest reading time.
