What is "skeuomorph"

n. A design feature copied from a similar feature in another object, even when not functionally necessary. (From 1889.)

A skeuomorph is a derivative object that retains ornamental design cues from structures that were necessary in the original. Examples include pottery embellished with imitation rivets reminiscent of similar pots made of metal and a software calendar that imitates the appearance of binding on a paper desk calendar.

Arguments in favour of skeuomorphism include that it makes devices easier to use for people familiar with the older devices that are imitated. Arguments against include that it takes up more screen space on digital devices, and may be more complex and more difficult to learn than a straightforward interface without it.

More recently there has been a move away from skeuomorphism, including at Apple Inc, whose operating system under the leadership of Steve Jobs formerly championed the approach.
