Individual subject data
The following images show the logged data for each subject. The two subjects
considered to be outliers are shown at the end of this set.
For each subject there are 6 images. The top 3 images show the subject's
brightness settings under each of the 3 different ambient lighting conditions.
The bottom 3 images show the percentiles of the relative luminance values
of the video
being viewed during the session. Note that each set of 3 bottom images
is the same; only the ordering is different, due to the random orderings
for different subjects. The time scale of each pair (top and bottom)
of images is aligned so that one may compare image brightness over time
with the subject's settings over the same time. We did not find any
correlation between the relative luminance of the video content
and the temporary brightness adjustment.
