Industrial designer Henry Dreyfuss’s design ground rules:
We bear in mind that the object being worked on is going to be ridden in, sat upon, looked at, talked into, activated, operated or in some other way used by people.
When the point of contact between the product and the people becomes a point of friction, then the Industrial Designer has failed.
On the other hand, if people are made safer, more efficient, more comfortable — or just plain happier — by contact with the product, then the designer has succeeded.
