Designing a good interface isn't easy. Users demand software that is well-behaved, good-looking, and easy to use. Your clients or managers demand originality and a short time to market. Your UI technology — Web applications, desktop software, even mobile devices — may give you the tools you need, but little guidance on how to use them well.



UI designers over the years have refined the art of interface design, evolving many best practices and reusable ideas. If you learn these, and understand why the best user interfaces work so well, you too can design engaging and usable interfaces with less guesswork and more confidence.
