define interface metaphor and analogies

Interface Metaphor:

An interface metaphor is a set of user interface visuals, actions and procedures that exploit specific knowledge already existing in the user's mind. Essentially, it's a way to use something that the user is already familiar with to explain or facilitate the understanding of something more complex. For example, the desktop metaphor used in many computer operating systems, where files and applications are represented as icons, is a type of interface metaphor.

Analogies:

Analogies are comparisons between two things that are typically thought of as unlike but have something in common. They can provide a way to think about a process or relationship. For example, "Just as a sword is the weapon of a warrior, a pen is the weapon of a writer." Here, the analogy is used to highlight the power of writing by comparing it to the physical power of a warrior's weapon.
