You think your brain understands what you see. It is not
true because your brain is interpreting what you see. When people look at
three-dimensional objects, it enters the retina as two-dimensional. But, then
the two-dimensional image is sent to visual cortex in the brain to be
recognized as a three-dimensional image. The fusiform face area is in the
brain, not part of the visual cortex (FFA). We depend on to recognize faces
faster than objects. People who have autism cannot use the FFA for face
recognition. They see faces the same as objects. More men than women that have
color-blindness since men only have one X-chromosome, women have two
X-chromosome. A color blindness person may not recognize the difference in
color or the color disappears.
Many people may recognize different colors that have certain meaning in
different cultures. For example, the red means financial trouble, danger or
stop. Green means money, environment, and “go”. Since different cultures have
color purpose, you have to consider the color selection you use.
Geon (geometric icon) is to use basic shapes to identity
objects.
FFA (fusiform face area) allows faces to bypass the brain’s
usual interpretive channels (visual cortex) and help the people identify faces more
quickly than objects.
Canonical perspective is usually drawn from a perspective
slightly above looking down and nothing askew straight from left to right.
Affordance is a visual clue to the function of an object.
