Users
"Users are not designers."
Jakob Nielsen, Usability Engineering, p. 12
"We don't want to figure out what all those buttons do or why they are set up the way they are. We just want to get on with our lives and do our jobs well. When we make use of technology, we want to focus on achieving our goals, not on deciphering the technology. The design should be in the background of our attention."
Kim Vicente, The Human Factor, p. 34.
"There's something very odd going on here. If designers made completely unrealistic assumptions about the physical world when designing technology, then we would blame them (and likely sue them) for technical incompetence. Yet when they make grossly unrealistic assumptions about human nature... we don't blame the designers, we blame the unfortunate people who are just trying to do what the design requires."
Kim Vicente, The Human Factor, p. 45.
