Kill the Design by Committee in its tracks.
Drop some science on their asses.It’s not all about color chips and thinking Papyrus is a pretty font.
Sounds like High brow Graphic Design speak to me.
Gestalt School of Psychology, originated in Germany by Dr. Max Wertheimer
began to provide simple and convincing evidence about how humans organize group visual elements so that they areperceivedas wholes.
Gestalt principals of perception: reveal the visual characteristics that incline us to group objects together.
Influenced by theories being formulated in physics in the late 1800s and early 1900s (electricity, magnetism and gravity).
Hypothesized that a field existed, and that this field held these elements with some sort of sympathetic force.
The field elementsinfluenceone another; they either attract or repel.
Obsessed with the figure ground relationship:
Elements are perceived as either figures (distinct elements of focus) or ground (the background or landscape on which the figures rest).
Gestalt psychologists attempt to discover refinements of the law of prgnanz, which allow us to predict the interpretation of visual sensation through “Properties of Perception”:
Instead, the dog is perceived as a whole, all at once.
For instance, a triangle will be perceived in picture A, although no triangle has actually been drawn.
In pictures B and D the eye will recognize disparate shapes as \"belonging\" to a single shape.
in C a complete three-dimensional shape is seen, where in actuality no such thing is drawn.
This is seen for example in the Necker cube.
Objects in A in the figure are all immediately recognized as the same basic shape, which are immediately distinguishable from the forms in B.
They are even recognized despite perspective and elastic deformations as in C, and when depicted using different graphic elements as in D.
This is where the rubber hits the road.
(Tufte encourages complexity, he thinks your readers are smart. I tend to agree.)
Impossible to see visual column 2 and 4 - except as ground (figure/ground relationship).
Symmetry facilitates grouping.
YEAH? its not - it’s broken and independent.
Continuity explains how the indention of text works as a means to group information.
Sneaky trick.
Elements with the same moving direction are perceived as a collective unit
Elements with the same moving direction are perceived as a collective unit
Elements with the same moving direction are perceived as a collective unit
Elements with the same moving direction are perceived as a collective unit
So be smart about your grouping - because we can instinctively tell when you’re not.
And it’ll piss your users off.
