To make matters more critical, an application which conforms to the well-known W3C accessibility standards is not necessarily usable for handicapped persons. In fact, the user experience, when accessing a complex Web application, using for example screen readers, tends to be far from friendly. In this paper we present an approach to safely transform Web applications into usable and accessible ones. The approach is based on an adaptation of the well-known software refactoring technique. We show how to apply accessibility refactorings to improve usability in accessible applications, and how to make the process of obtaining this "new" application cost-effective, by adapting an agile development process UR - http://dx.doi.org/10.1007/978-3-642-17616-6_49 ER -
