Attractive things work better When you wash and wax a car, it drives better, doesn’t it? Or at least feels like it does.

Good design is also an act of communication between the designer and the user, except that all the communication has to come about by the appearance of the device itself. The device must explain itself.

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

If people keep buying poorly designed products, manufacturers and designers will think they are doing the right thing and continue as usual.

How do you discover a need that nobody yet knows about? This is where the product breakthroughs come through.

Rule of thumb: if you think something is clever and sophisticated beware-it is probably self-indulgence.

What makes something simple or complex? It's not the number of dials or controls or how many features it has: It is whether the person using the device has a good conceptual model of how it operates.
