In this chapter
As shown in previous chapters, AJAX offers an exciting new set of possibilities, but it also creates new challenges. A big part of those challenges is creating a new interaction model that works not only from a technology standpoint, but also from the users' perspective. Your new designs need to work and to be easy to discover. In addition, they need to allow for productive, regular use. This chapter looks at usability, provides a set of principles that help you create highly usable interfaces, and shows real examples to illustrate some common mistakes and ways to avoid them.
