"Eyeglasses are a good tool -- you look at the world, not the eyeglasses. The blind man tapping the cane feels the street, not the cane" - Mark Weiser, Xerox Parc 1994 When tools become invisible, i.e. we focus on the actions we're performing to accomplishing our goals, that is when tools are at their best. The Action-centered design framework, focuses people to think action first, and then design tools according to them.
