An object is ergonomic when it is in perfect harmony with the human body.
An object is ergonomic when it is in perfect harmony with the human body, when it provides comfort and efficiency and when it offers fluidity and ease to the gesture, posture or movement. Ergonomic is what is light (easy to lift, put down, take out and put away), not very bulky (small, compact) and pleasant to use (fits well in the hand, fits the shape of the body). On the contrary of things like feelings or sensations (that we cannot weigh, measure), why, when we have the possibility, not use numbers, weights, measures and their magnificent precision?
I have not failed. I've just found 10,000 ways that won't work.
The most consequential assumption behind all his work (ed. Don Norman, leading authority on design and usability) is that even if human error is to blame, it is hard to imagine any human not making these errors. Humans might fail—but they are not wrong. And if you try to mirror their thinking a little, even the stupidest and strangest things that people do have their own indelible logic. You have to know why people behave as they do—and design around their foibles and limitations, rather than some ideal.
His great insight was that no matter how complex the technology, or how familiar, our expectations for it remain the same. […]. This is what you have to understand if you are to design an app that people can use the first time they try it, or a plane that humans won't crash, or a nuclear reactor that humans can't cause to melt through the continental shelf.
The creative act is a letting down of the net of human imagination into the ocean of chaos on which we are suspended, and the attempt to bring out of it ideas.
It is the night sea journey, the lone fisherman on a tropical sea with his nets, and you let these nets down - sometimes, something tears through them that leaves them in shreds and you just row for shore, and put your head under your bed and pray.
At other times what slips through are the minutiae, the minnows of this ichthyological metaphor of idea chasing.
But, sometimes, you can actually bring home something that is food, food for the human community that we can sustain ourselves on and go forward.
[Many people] think it means accept failure with dignity and move on. The better, more subtle interpretation is that failure is a manifestation of learning and exploration. If you aren’t experiencing failure, then you are making a far worse mistake: You are being driven by the desire to avoid it. And, for leaders especially, this strategy — trying to avoid failure by out-thinking it — dooms you to fail.
