3.5.2 Reading Task
Measures The additional automatic measures that were performed during the reading task were task completion time and the scrolling behavior. The prototype used a smooth scrolling technique that fades out the scrolling speed before the text stays in its fixed position. Thus, it was possible to flick the text. The scrolling was measured in pixels and shows the overall distance of the thumb movement on the screen. The reading comprehension results between the different settings were also collected. Every single participant had to read two passages of text in each setting.
In summary, the study design was:
16 Users x
2 Passages of text x
4 Settings (1 standing + 3 walking conditions)
= 128 measures overall
