Recent legal changes have increased the need for developing accessible user interfaces in computer-based
systems. In this sense, previously existing user interfaces are intended to be modified and new user interfaces
are intended to be designed taking accessibility guidelines into account. Typically, model-based
approaches have been used when developing accessible user interfaces or redefining existing ones. But
the use of static models leads to the development of not dynamically adaptable user interfaces. Dynamic
adaptation in accessible user interfaces is important due to the fact that interaction difficulties on people
with disabilities may change through use. In this paper, we present some contributions that can be
obtained from the application of the Dichotomic View of plasticity in the personalization of user interfaces.
With the double perspective defined in this approach, it is intended to go further from a mere adaptation
to certain user stereotypes, offering also a dynamic support to real limitations or difficulties users
can encounter during the use of the UI. This goal is achieved analyzing user logs by an inference engine
that dynamically infers modifications in the user interface to adjust it to varying user needs. A case study
is presented in order to show how the guidelines and software support defined in the Dichotomic View of
plasticity can be applied to develop a component for a particular system aimed at performing dynamic
user interface adaptations with accessibility purposes. This approach includes some innovations that
make it different from conventional adaptable mechanisms applied to accessibility in some important
aspects.
