Putting the user in user-interface testing

Discusses one of the most basic topics in user-interface design: how to run a user test. No matter how good we are at designing a user interface, we must always test it with real users to see whether it is as usable as we hope. The three main rules of user testing are: get real users, have them do real tasks, and shut up while they are trying. Tools, techniques and concepts to optimize user interfaces are described, and ethical issues are discussed.
