Friday quote: Friction

“If the point of contact between the product and the people becomes a point of friction, then the Industrial Designer has failed.”

Henry Dreyfuss, Designing for People, 1955


Cognitive friction
is one thing, and generally a result rather than a deliberate strategy; process friction is something else, and can very much be a deliberate strategy, as well as an accidental consequence of poor or badly thought-out interaction design. This is closer to what Dreyfuss is getting at, I think.

"I made up my mind... that I would never try to reform man — that’s much too difficult.
What I would do was to try to modify the environment in such a way as to get man moving in preferred directions."
R. Buckminster Fuller, 1966
