Personalization of user interfaces for browsing content is a key concept to ensure content accessibility. In this direction, we introduce concepts that result in the generation of personalized multimodal user interfaces for browsing XML content. User requirements concerning the browsing of a specific content type can be specified by means of user-friendly description languages. According to these specifications, transformation rules are generated and applied to content to produce personalized user interfaces for browsing the content. With the emergence of the semantic Web and connected XML applications, such customized multimodal user interfaces can be helpful to many kinds of users, especially to individuals with various types of impairment.
