Growing
up, I can recall my mother telling me that I perceive things
differently than most people. And when I think about it, there must
be a nugget of truth in this. Over the course of my life, variations
of this statement have resounded in my ears; from an irate boyfriend
screaming "Your perception is all screwed up!" to "Wow,
I've never looked at it in that way before". Everything that our
eyes encounter takes on new dimension and meaning as our mind spins
it in the gossamer of perception and interpretation.
Vision
is not merely a function of our eyes, but a joint venture of our eyes
and brain. Our eyes send simple signals of edge, shape and motion to
our brains, where they are constructed into images. Our brains
interpret these signals based on pattern recognition, and then
seamlessly cause us to perceive whatever the object might be. One
example of pattern recognition is the the fact that motorcycles and
bicycles get hit every day by motorists who were looking right at
them. Most drivers are looking for cars.
Perception,
the brain's personal spin on things, is not so easily explained. It
is that ethereal factor that determines beauty...that detects the
"mood" of a work of art. Perception varies as much as we
are individuals, reading a myriad of connotations into the images our
brains have stitched together from those signals sent from our eyes.
In
design, we make use of pattern and consistency to produce a positive,
harmonious visual experience. We create interest by variations in
pattern and movement in line and shape. We are able to direct the eye
of the viewer by way of composition and contrast. Understanding the
way that we see and perceive will enhance our ability to successfully
incorporate the elements and principals of design into our work.
