User-centered Design of Accessible Web and Automation Systems

Abstract

During the past decades, Web applications and industrial automation systems – and their combination in e.g. pervasive computing – have gained more and more importance in our daily life. However until now, user interface accessibility remains as an important quality aspect and a challenge for implementation. The majority of accessibility requirements are shared between these types of systems. This paper presents a research on user-centered design and model-driven development of accessible user interfaces. The approach integrates the product requirements of Web and industrial automation systems. The use of different interface models enables the description of particular UI aspects as structure or behavior. User-centered design facilitates the integration of user-driven accessibility requirements. The focus on the requirements of software development processes for Web and automation systems shows that research on accessible user interfaces has to consider the requirements of product analysis and design. Additionally, upcoming daily use in pervasive computing requires a comparison of requirements for both system types.
