Natural mapping

(in HCI) 자연스러운 매핑.

Donald Norman의 정의:

Natural mapping, by which I mean taking advantage of physical analogies and cultural standards, leads to immediate understanding. For example, a designer can use spatial analogy: to move an object up, move the control up. To control an array of lights, arrange the controls in the same pattern as the lights. Some natural mappings are cultural or biological, as in the universal standard that a rising level represents more, a diminishing level, less. Similarly, a louder sound can mean a greater amount. Amount and loudness (and weight, line length, and brightness) are additive dimensions: add more to show incremental increases. Note that the logically plausible relationship between musical pitch and amount does not work: Would a higher pitch mean less or more of something? Pitch (and taste, color, and location) are substitutive dimensions: substitute one value for another to make a change. There is no natural concept of more or less in the comparison of different pitches, or hues, or taste qualities. Other natural mappings follow from the principles of perception and allow for the natural grouping or patterning of controls and feedback. —The design of everyday things

Colin Ware는 유사한 개념을 “semantic mappings”라고 부른다:

Other semantic mappings relating to quantity may be more universal. Quantities that are larger should generally be mapped to colors that are more distinct. This visually means that more saturated colors should be used to represent greater quantity. Similarly, darker colors on a light background or lighter colors on a dark background can be used to indicate greater quantity. —p84, Visual thinking for design
