Apply surface mimicry — making an interface element look like a familiar physical object to communicate its purpose at a glance. Use when introducing a control or container that has no native UI vocabulary, designing a niche product that benefits from a recognizable visual reference (a journal that looks like a journal, a wallet that looks like a wallet), or evaluating whether visual skeuomorphism is communicating or just decorating. Surface mimicry is most useful for novice users in unfamiliar mediums; it becomes anachronistic as the source fades or as users learn the abstract conventions.
