Just how do I design if not with prototyping? An excellent question. The short answer is 'on paper.'
Alan CooperBecause computers have memories, we imagine that they must be something like our human memories, but that is simply not true. Computer memories work in a manner alien to human memories. My memory lets me recognize the faces of my friends, whereas my own computer never even recognizes me. My computer's memory stores a million phone numbers with perfect accuracy, but I have to stop and think to recall my own.
