Designing for accessibility involves integrated theories from Human-Centered Design(HCD), accessibility research, disability studies, occupational therapy(OT) and assistive technology(AT) development. Aligning on a unified inclusive design process is challenging due to numerous roadblocks such as limited access to people with disabilities, insufficient tools and methodologies for designers and inadequate design training among clinicians. This paper explores the gaps in these interconnected fields and proposes a new approach to bridge these gaps. By focusing on designing based on body functions, the paper introduces new terminologies (functional affordances, breakdown scenarios) and methodologies (extended task analysis, task-ability statements, extended SCAMPER) to compliment ‘designing for many’ and ‘adapting for one’. ‘How do we adapt for many?’
