Most of these principles can be applied to either command-line or graphical environments. I welcome suggestions for changes and additions -- I would like this to be viewed Essay metaphor an "open-source" evolving document. The principle of user profiling -- Know who your user is.
Before we can answer the question "How do we make our user-interfaces better", we must first answer the question: A design that is better for a technically skilled user might not be better for a non-technical businessman or an artist. One way around this problem is to create Essay metaphor models.
The result of this process is a detailed description of one or more "average" users, with specific details such as: What are the user's goals? What are the user's skills and experience? What are the user's needs?
Armed with this information, we can then proceed to answer the question: How do we leverage the user's strengths and create an interface that helps them achieve their goals?
In the case of a large general-purpose piece of software such as an operating system, there may be many different kinds of potential users. In this case it may be more useful to come up with a list of user dichotomies, such as "skilled vs. Another way of answering this question is to talk to some real users.
Direct contact between end-users and developers has often radically transformed the development process. The principle of metaphor -- Borrow behaviors from systems familiar to your users.

In addition to the standard transport controls play, rewind, etc. This concept of "extendibility" is what distinguishes a powerful metaphor from a weak one.
There are several factors to consider when using a metaphor: Once a metaphor is chosen, it should be spread widely throughout the interface, rather than used once at a specific point.
Even better would be to use the same metaphor spread over several applications the tape transport controls described above is a good example. Don't bother thinking up a metaphor which is only going to apply to a single button.
There's no reason why an application cannot incorporate several different metaphors, as long as they don't clash. Music sequencers, for example, often incorporate both "tape transport" and "sheet music" metaphors.
Metaphor isn't always necessary. In many cases the natural function of the software itself is easier to comprehend than any real-world analog of it. Don't strain a metaphor in adapting it to the program's real function. Nor should you strain the meaning of a particular program feature in order to adapt it to a metaphor.
Incorporating a metaphor is not without certain risks. In particular, whenever physical objects are represented in a computer system, we inherit not only the beneficial functions of those objects but also the detrimental aspects. Be aware that some metaphors don't cross cultural boundaries well.
For example, Americans would instantly recognize the common U.
