Once the product's task is known, design the interface first; then implement to the interface design.

An interface is humane if it is responsive to human needs and considerate of human frailties.

If our field is "to advance", we must - without displacing creativity and aesthetics - make sure our terminology is clear.

What users want is convenience and results.

Imagine if every Thursday your shoes exploded if you tied them the usual way. This happens to us all the time with computers, and nobody thinks of complaining.

I hate mice. The mouse involves you in arm motions that slow you down. I didn't want it on the Macintosh, but Jobs insisted. In those days, what he said went, good idea or not.

A well-designed and humane interface does not have to be split into beginner and expert subsystems.
