Abstract The Web is constantly evolving into an unprecedented and continuously growing source of knowledge, information and services, potentially accessed at by anyone anytime, and anywhere. Yet, the current uptake rates of the Web have not really reached their full potential, mainly due to the design of modern Web-based interfaces, which fail to satisfy the individual interaction needs of target users with different characteristics. A common practice in contemporary Web development is to deliver a single user interface design that meets the requirements of an “average” user. However, this “average” user is in fact an imaginary user. Often, the profiles of a large portion of the population, especially that of people with disability, elderly people, novice users and users on the move, differs radically. This work aims at supporting and providing the means for the development of inclusive Web-based interfaces that are capable to adapt to multiple and significantly different user profiles. To this purpose, the /Unified Web Interfaces/ (UWIs) method is proposed as an alternative approach to the design and development of Web-based applications. This novel method builds on well-established /Design for All/ principles and on the /Unified/ /User Interfaces/ methodology. Furthermore, /EAGER/, an advanced toolkit, is provided as a means to facilitate Web developers in following the proposed UWI method. EAGER allows /Microsoft® .NET/ developers to create interfaces that conform to W3C accessibility guidelines, and which are able to adapt to the interaction modalities, metaphors and user interface elements most appropriate to each individual user, according to profile information based on user and context specific parameters. As a means to validate the proposed toolkit, a prototype, fully functional Web portal was implemented by means of the EAGER toolkit and evaluated in terms of its accessibility and usability to all. Overall, this development confirmed that EAGER offers significant benefits to developers and ensures the delivery of accessible, usable and satisfying Web-based interfaces. The process of employing EAGER is significantly less demanding in terms of time, experience and skills required from the developer than the typical process of developing Web interfaces for the “average” user. Finally, this thesis discusses potential extensions of this work.
