The physical demand was rated least in the standing condition. The frustration level is highest in the walking condition with a small text size and gets less with a larger text size. Overall, the workload also decreases with larger text sizes and a comparison between the control condition and the walk/small condition shows that the effect of movement on workload is larger than the change in text size. A non-parametric Friedmann test did not show a significant effect of text size on overall workload (p > .05). However, regarding just the mental workload, the results reach significance (χ2(2) = 7.24, p < .05). A Wilcoxon test, used to follow-up this result, shows that between the small and the medium text size as well as between the medium and the large text size no significance was reached (p > .05). A non-parametric Wilcoxon signed-ranks test shows that the workload during the standing condition (Mdn = -1.14) was significantly lower than during the walking condition (Mdn = -.33), Z = 3.42, p
