The intrinsic value of icons is pretty much apparent in modern user interfaces. Icons are visual metaphors that only take up a small amount of space but can carry a significant meaning. They provide users with intuitive access to actions and applications, or represent an immediate status of an object. To make icons seem valuable in this sense, one needs to focus on two things while designing them: first, consistency of visual style, and second, appropriate mapping of metaphors and symbols in order to convey the correct perceived meaning of an icon.
