Skeuomorphism

A skeuomorph (also spelled skiamorph, /ˈskjuːəˌmɔːrf, ˈskjuːoʊ-/)[1][2] is a derivative object that retains ornamental design cues (attributes) from structures that were necessary in the original.[3] Skeuomorphs are typically used to make something new feel familiar in an effort to speed understanding and acclimation.

Virtual skeuomorphs can also be auditory. The shutter-click sound emitted by most camera phones when taking a picture is an auditory skeuomorph.

Apple Inc., while under the direction of Steve Jobs, was known for its wide usage of skeuomorphic designs in various applications. This changed after Jobs's death when Scott Forstall, described as "the most vocal and high-ranking proponent of the visual design style favored by Mr. Jobs", resigned. Apple designer Jonathan Ive took over some of Forstall's responsibilities and had "made his distaste for the visual ornamentation in Apple's mobile software known within the company".[24] With the announcement of iOS 7 at WWDC in 2013, Apple officially shifted from skeuomorphism to a more simplified design, thus beginning the so-called "death of skeuomorphism" at Apple.
