ComplexityCraftsmanship&

extraneous redundancy

lack of careful diligence

Too many fontsToo many colorsToo many linesOverdone effects

Too many iconsNo hierarchyEverything emphasizedNo useful groupings

Every button, icon, text, tab, menu item is another visual & cognitive signal that a user must process & learn, thus increasing complexity and error! Even for a split second.

Dialogues (not dialogs)

Start with target audience

Consider diverse contexts

Apply OS guidelines

YMMV

PrinciplesPatterns

& potent, useful

clear, effective

But#what#about#that#damn#UI?

Do’s#&#Don’ts

Don’t clutter the screen with noise

Don’t use every font or color in the palette

Don’t fill every inch of the screen with “stuff”

Don’t be verbose and redundant

Don’t have slow irritating performance

Don’t leave users hanging with no exit

Don’t be painful and frustrating

Take

note!Do’s#&#Don’ts

Do leverage a good metaphor

Do use well-defined, clean grid layouts

Do use fonts sparingly

Do apply color judiciously

Do use clear, concise language

Do use icons purposefully

Do create clear behaviors with feedback

(No more than 3+)

(No more than 5+)
