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

If I am correct, the use of a product based on modelessness and monoty would soon become so habitual as to be nearly addictive, leading to a user population devoted to and loyal to the product.

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

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.

When you have to choose among methods, your locus of attention is drawn from the task and temporarily becomes the decision itself.

I am confident that we can do better than GUIs because the basic problem with them (and with the Linux and Unix interfaces) is that they ask a human being to do things that we know experimentally humans cannot do well. The question I asked myself is, given everything we know about how the human mind works, could we design a computer and computer software so that we can work with the least confusion and greatest efficiency?

Users do not care about what is inside the box, as long as the box does what they need done.
