Evaluation
Software designers attempt to make computer applications easier to use for both novice and expert users by creating concrete metaphors that resemble the users' real-world experiences. Continual technological improvement has made metaphors depict these real-world experiences more realistically to ultimately enhance interface performance. Beginning users, however, could use a sort of help box, because the metaphor is not always going to be clear enough for them to understand, no matter how much effort its programmers devote to making it resemble something the users understand. Experts, on the other hand, understand what is going on with the technical aspects of an interface metaphor. They know what they want to do and they know how to do it—-and so they design shortcuts to facilitate achieving their goals.
While the concept behind interface metaphors appears simple (to promote more efficient facilitation of a computer), a lack of empirical evidence exists to support these claims. Little research has actually been completed that demonstrates the benefits of implementing metaphors in computer systems as well as what makes a metaphor most effective. Therefore, it is imperative that more research be done to discover how to further improve interface metaphors so that both novice and expert computer users are able to increase their performance.

Famous quotes containing the word evaluation:
“Evaluation is creation: hear it, you creators! Evaluating is itself the most valuable treasure of all that we value. It is only through evaluation that value exists: and without evaluation the nut of existence would be hollow. Hear it, you creators!”
—Friedrich Nietzsche (1844–1900)
“Good critical writing is measured by the perception and evaluation of the subject; bad critical writing by the necessity of maintaining the professional standing of the critic.”
—Raymond Chandler (1888–1959)
