In this slides, we describe a system for adapting websites based on an annotation approach. The system adapts annotated websites according to the user characteristics. The core of the system is composed of a repository containing a comprehensive set of adaptation techniques. 99 techniques have been identified and classified, 48 of them have been fully implemented in the system. This wide range of implemented techniques provides the system with the necessary mechanisms for adapting diverse aspects of website interfaces, such as the content to display, the layout and the structure. The techniques to apply for a given user are inferred according to the information stored in an ontology. This defines the bases for associating user characteristics with the adaptation techniques to apply for specific interaction elements annotated in a website. An annotation language based on the roles and properties of WAI-ARIA has been elaborated. Therefore, any website annotated in this language can be adapted. This adaptation system has been applied to two different websites and adapted interfaces have been obtained for three different user groups.

3. Problem Definition: Problem
• One UI for All
• New barriers are being created
– Dynamic Content
– Video
– Chat
• WAI-ARIA allows the addition of semantic
annotations to HTML elements
– Assistive Technologies can better manage interaction
elements
• HTML5 covers some of the lack of semantic
meaning in previous HTML versions

25. Conclusions
• The system allows personalizing web
interfaces based on the ontology
• High number of collected techniques
• Extensible
• Annotation process needs to be
more automatic

26. Future Work
• Improve the Add-on to track
users’ interaction and validate
the system
• Extend the number of techniques
• Develop an annotation tool
• Investigate constraints between
adaptation techniques
