Design Principles are for humans, not machines

Don Norman and Bruce Tognazzini explain how and why they formalised the principles of good, understandable design in Apple’s Human Interface Guidelines (and much more)

If there’s something to take away from the reading of this article, it is this:

“It’s important to note that these principles reflect the needs, desires, and abilities of human beings, not the machines they use. The principles are as applicable to today’s interfaces as those of the 1980s, and they will remain applicable until people evolve, a rather slow process indeed.”

That’s what principles are made for: to last the passing of time. To be universally valid, no matter when, where and how they are applied. Trends come and go; how the human brain works remains (almost) the same.
