However, these guidelines have been show to be inadequate when assessing dynamic Web applications. Furthermore, when considering adaptive Web applications, another layer of dynamism is introduced, further complication the problem. This chapter presents a framework for accessibility evaluation of adaptive Web applications, expanding on previous work for evaluating dynamic Web applications. The framework will be described in the context of an evaluation of TV based Web applications, and the results will assist in the characterization of the accessibility of this particular field of Web applications.
