Figure 1.
Mean error rates (%) for the comprehension questions in the present study.
Error bars represent the standard error of the mean calculated for the within-participants factor MEDIUM according to the procedure outlined in [60].
Figure 2.
Ratings for the pleasantness of reading (choice of preferred reading medium) in absolute numbers of answers.
Note that two participants were excluded from this analysis: one did not provide an answer, while the other chose two reading devices (tablet computer and book page).
Figure 3.
Ratings for the best readability / legibility across the different reading media in absolute numbers of answers.
Note that three participants were excluded from this analysis: one did not provide an answer, while the other two chose two reading devices (tablet computer and book page).

Mean summed fixation durations per page of text (in seconds).
Error bars represent the standard error of the mean calculated for the within-participants factor MEDIUM according to the procedure outlined in [60].
