Accessibility studies. Abuses, misuses and the method of poietic design

Over the past several decades, accessibility has been increasingly pervading a vast range of fields, producing a large number of new ideas, theories, and innovations that have already proven to be quite fruitful. A closer look at how accessibility has entered and developed in various research fields shows that said fields have experienced fundamental changes: a shift from particularist accounts to a universalist account of access, a shift from maker-centred to user-centred approaches, and a shift from reactive to proactive approaches. Through these processes, accessibility has birthed new areas within those fields, that have been gradually converging to constitute the wider field of accessibility studies. The nature and position of accessibility studies has now become a central topic. This ongoing progression of conceptual clarification may bear some misunderstanding and misinterpretations along the way. In the paper, I first briefly review the principal traits of the process of formation of accessibility studies; then address some possible misconceptions; and finally, introduce a first, very general sketch of poietic design, a method proper to accessibility studies.
