There's this door on the tenth floor of the Vocs media office that I hate so much damage period of Dore Wrong, pretty regularly have you seen. People misuse concept me too Kelsey, but here's the thing. As soon as you start looking for confusing doors, they bar every its push. Why roman Mars. We know that this is ninety nine percent invisible. His doors, you hate or called Norman What's a Norman door, Don Norman wrote the essential book about design here,

the Norman of the Norman to arrive, and where is this guy? You must go to San Diego, ok, I'm dying Norman. I am sure you know it's hard. Describe what I well he's been a professor of psychology, professor of cognitive science, professor of computer science, a vice president of advanced technology at apple, but for our emphasis. Notwithstanding a year in England, I tried so frustrated with my inability to use the light switches and the water tabs, and the dollar is even wrote this if I continue you're wrong, Is it my fault? No, back. If you continually get it wrong, is a good one, Their people continue to get a good sign. a really bad door.

That is why we have have a sign that says push or pulled. Why not make it up? it can be obvious design right. There are a couple really simple basic principle of design, and one of them will call discover ability. When I look at something, I should be able to discover what operations I can hear the principle applies to a whole lot more than doors It's amazing with many of our computer systems. Today ether, There's no way of knowing was possible should I am tap at once or twice or even trivial discover ability when is not there Well, you don't worry you something Another is feedback somebody time, there's no feedback. You have no idea what happened or why it happened.

and these principles form the basis of how designers and engineers work today commonly known as user or human centred design. I've decided at one point. The word user was the big degrading. Why not call people, people and its amazingly, simple and amazingly seldom practice we got into a cheerful, goes around there, sir go out. We observe what is happening today. Reserve people doing tat and from that we say, oh, we some ideas, here's what we should perhaps propose to do. Then you put Take your solution and test. It went off. These are wrong. First serving around the circle? We do a better job of making your vice until the point we are actually making something that really works, and this process has spread all over the world and it turns out its improving lot from better everyday things like the ones that Donald about using the same process dissolve huge problems and public health in developing countries,

It was so much fun collaborating with ninety nine percent, visible, as you can see some approval, speaking made over here, but obviously
