Not obviuous for me...
The assertion that angular guages are easier to read is backed up by
countless perception and human factors studies. It is also
corroborated by studies of the stimulation network pre-processing that
takes place right in the retina at the back of the eye.
Human factors texts such as McCormick's, and physiology texts on
sensation and perception deal with this topic at great length.
Thanks, and best regards to all
