The world is complex, and so too must be the activities that we perform. But that doesn't mean that we must live in continual frustration. No. The whole point of human-centered design is to tame complexity, to turn what would appear to be a complicated tool into one that fits the task, that is understandable, usable, enjoyable.

The design of everyday things is in great danger of becoming the design of superfluous, overloaded, unnecessary things.

It is not enough that we build products that function, that are understandable and usable, we also need to build products that bring joy and excitement, pleasure and fun, and, yes, beauty to people's lives.

When you have trouble with things—whether it's figuring out whether to push or pull a door or the arbitrary vagaries of the modern computer and electronics industries—it's not your fault. Don't blame yourself: blame the designer.

I think a successful company is one where everybody owns the same mission. Out of necessity, we divide ourselves up into discipline groups. But the goal when you are actually doing the work is to somehow forget what discipline group you are in and come together. So in that sense, nobody should own user experience; everybody should own it.

I believe that robots should only have faces if they truly need them

Only the most sophisticated of beings can lie and cheat, and get away with it.
