gestalt principles of visual perception
over 100 years ago, the gestalt school of psychology set out to
understand how individuals perceive order in the world
around them. what they came away with was six principles
that define how people interact with and create order out of
visual stimuli.
,1. proximity
2. similarity
3. enclosure
4. closure
5. continuity
6. connection
proximity
we tend to think of objects that are physically close together
as belonging to part of a group. the proximity principle is
demonstrated below:

we can leverage this way that people see in table design. by
virtue of differentiating the spacing between dots, your eyes

similarity
objects that are of similar color, shape size, or orientation are
perceived as related or belonging to part of a group
enclosure
we think of objects that are physically enclosed together as
belonging to part of a group. it doesn't take a very strong
enclosure to do this: light background shading is often
enough.
closure
the closure concept says that people like things to be simple
and to fit in the constructs that are already in our heads.
because of this, people tend to perceive a set of individual
elements as a single, recognizable shape when they can. when
parts of a whole are missing, our eyes fill in the gap.
