Aesthetic?
“of, relating to, or dealing with or the beautiful”
“pleasing in appearance”
“attractive”
“appreciative of, responsive to, or about the beautiful”
“responsive to or appreciative of what is pleasurable to the senses”
Wait, that seems very subjective…
“of, relating to, or dealing with or the beautiful”
“pleasing in appearance”
“attractive”
“appreciative of, responsive to, or about the beautiful”
“responsive to or appreciative of what is pleasurable to the senses”
How is Aesthetic more than just personal taste?
Can we evaluate a design in a way that is not just
subjective?
How do we know when something has aesthetic
value?
…and why bother?
Aesthetic-Usability Effect
The Aesthetic-Usability Effect is a condition
whereby users perceive more aesthetically
pleasing designs to be easier to use than less
aesthetically pleasing designs.”

“The best designers sometimes disregard the
principles of design. When they do so, however,
there is usually some compensating merit attained
at the cost of the violation. Unless you are certain
of doing as well, it is best to abide by the
principles.”
– William Lidwell

On the Laws of Colour
The objective laws of form and
colour help to strengthen a
person's powers and to expand
his creative gift. ”

Colour can:
• Carry cultural meaning
• Impact accessibility
• Convey brand, emotion
• Emphasize interface elements

Simple design in practice
A Quick Example…
Simple Rules for Better Design
1. Be Consistent
Everything - Font sizes, colours, spacing, alignment should be
universal for agiven interface.
Users will waste time trying to figure out why something is
minutely different.
2. Create a context hierarchy
3. Facilitate Unitization
Use Gestalt principles to imply and clarify groups
Use familiar objects and fonts
Avoid ambiguity (be consistent!)
4. Take Advantage of Mental Models
5. A Picture’s Worth 1,000 Words
• There are loads of open-licensed icon and image libraries
available for use
6. Be mindful of colour choices
• The colourblind will thank you
• Cultural Differences
• Try not to use 100% black or white
There are many tools available to help
7. Use Grids when possible
