10.3.5 Results of Experiment 2: Influence of Human Factors
on Visual Discomfort
10.3.5.1 Comparison Between Experts and Naive Viewers
The BT scores of the Experiment 2 from experts and non-experts data are shown in
Fig.
10.10
. Both the experts and non-experts BT scores for the 15 planar motion
stimuli provide the same conclusion as found in Sect.

. The consistency of the
experts and naive viewers
test
results are: CC

RMSE
s exact test is applied on the raw pair comparison
data of the experts and naive viewers results, and there are in total 21 pairs
significantly different (

Thus, in general, the two experimental results are well correlated.

top two figures
are experts
results. The
bottom

two figures
are non-experts
results. The
different lines
in the

represent the different
velocity levels. The
vertical two dashed lines
represent the
