In Chapter 1 Norman, through a series of real-world examples (a number from instances in his own life), makes some compelling arguments for good and bad design. A faithful skeptic both of technology and “everyday things,” Norman places the burden of modern/contemporary (industrialized) society’s failures and frustrations with these things largely with poor design. (Though not necessarily, it should be noted, specifically with designers themselves, who, he notes, have a great number of competing and often forces looking to shape their work–from manufacturers to retailers to consumers).
One of Norman’s main points is that “one of the most important principles to design [is] visibility. The correct parts must be visible, and they must convey the correct message” (p. 4). He also places a great deal of value and importance on design elements of any given object having “natural signals, naturally interpreted, without any need to be conscious of them” (p. 4). Another element is the “mappings between what you want to do and what appears to be possible” with a given object (p. 4). These three concepts are substantially interrelated. For example, Norman notes, “[v]isibility indicates the mapping between intended actions and actual operations” (p. 8).
Norman summarizes the “fundamental principles of designing for people” as “(1.) provide a good conceptual model and (2) make things visible: (p. 13)”. Good conceptual model are comprised of a successful integration of the design model, “the designer’s conceptual model”; the user’s model, “ the mental model developed through interaction with the system,” and the system image, which “results from the physical structure that has been built (including documentation, instructions, and labels)” (p. 17).
One of the things that struck me when reading this chapter was the sheer number of man-hours lost on a daily basis, all around the world, to things like poorly designed doors/gateways, appliances, etc. (Even if someone has calculated it, I’m not sure that I’d want to see it.) I was also struck by some of the similarities between bad design and bad grammar–both lead to poor and inefficient communication, lost time, frustration, etc.
