Inclusive development: Software engineering requirements for universally accessible interactions

The notion of ‘universal access’ reflects the concept of an Information Society in which potentially anyone (i.e. any user) will interact with computing machines, at anytime and anyplace (i.e. in any context of use) and for virtually anything (i.e. for any task). Towards reaching a successful and cost effective realization of this vision, it is critical to ensure that the future interface development tools provide all the necessary instrumentation to support inclusive design, i.e. facilitate inclusive development. In the meantime, it is crucial that both tool developers and interface developers acquire awareness regarding the key development features they should pursue when investigating for the most appropriate software engineering support in addressing such a largely demanding development goal (i.e. universally accessible interactions). This paper discusses a corpus of key development requirements for building universally accessible interactions that has been consolidated from real practice, in the course of six medium-to-large scale research projects, all completed, within a 10 years timeframe.
