User Interface Modelling for Accessible Web Applications with the Unified Modelling Language

The design of accessible Web user interfaces (UIs) is a complex challenge for software architects and developers since the requirements are often respected too late in the development process. UI modeling allows research on particular aspects of accessibility requirements during the development process – especially during analysis and design. It is based on the description of user's workflow. Essential UI models are described. With Model-driven Design (MDD) and the Unified Modeling Language (UML) common standards of software engineering are used. In summary, the integration of accessibility in UI modeling helps to understand the needs during earlier development phases of software applications better.
