This, from an Eames video, feels more like something out of Dreyfuss’ Designing for People:
We have been looking at one invention which began pretty purely out of the conception of a need. The hope: to change the person who takes pictures from a harried offstage observer into someone who’s a natural part of the event. … In the end, it links the inventors, the engineers, the workers, the distributors, into one chain of craftsmanship.
The user is the final link. … We hope the user will fully complete the chain, gaining as much fun, as much sense of self, and as clear participation and stream of human creativity as did Edwin Land and the team who first made SX-70.
