Describe the goal of ergonomics; explain what is meant by a design that is natural, that uses metaphors, and that provides feedback; and give an example of each of these design aspects

What will be an ideal response?

ANSWER: Answer will include that the goal of human factors psychology, also called ergonomics, is to design machines and work environments so they are compatible with our sensory and motor capacities. (Examples of the design aspects will vary but must explain natural design, the use of metaphors and feedback.) Successful human factors engineering incorporates a natural design in the machines, that is, the design is based on perceptual signals that people understand naturally, without needing to learn them. For example, digital cameras look like cameras that use film. One way to create more natural designs is to use metaphors to create resemblances between different subjects. For example, the design of all current personal computers presents a "desktop metaphor" with "files," "folders," and a "trashcan." Effective designs also provide feedback, which is information about the effect of making a response. The audible click designed into many computer keyboards is a good example. Another example would be the artificial sounds engineered into many otherwise quiet electric cars to make it easier for pedestrians to detect their presence.
