Requirements for the successful market adoption of adaptive user interfaces for accessibility

The concept of adaptive user interfaces is a promising solution for providing users with a wide range of individual needs with accessible technology. Developers only have to implement one generic solution to offer a multitude of individually optimised concrete user interfaces. Whereas a lot of technical functionalities and characteristics of adaptive user interfaces are already solved, there is still no widespread market adoption of adaptive UI technologies. This paper presents a collection of requirements for adaptive user interface systems that can enable widespread market adoption. Furthermore it identifies strategies and individual answers, how these requirements can be addressed and met in future systems building on the Prosperity4all approach. It gives a comparison of existing research solutions and how they compare with the stated requirements.
