UD, ID, DfA, UX, UA: A terminology muddle

A hand holding a coloured pen is poised over a green post it note. There are drawings on the table and a smartphone. It indicates UX design.The aims of universal design (UD), inclusive design (ID), design for all (DfA), user experience (UX) and universal accessibility (UA), are basically the same – inclusion. So why should we be in a muddle about terms? For most designers and practitioners who understand the underpinning principle of inclusion, it’s not a big deal.  But shouldn’t the key issue be about implementation rather than discussing the nuances of terms? Even if we had one term, would that alter designer and practitioner attitudes towards inclusion?

Nevertheless, researchers find it frustrating not to have one term to cover the concepts. That’s because it makes it difficult to know if people are talking about the same thing when sharing research findings. The debate among academics has resulted in many papers on this topic. Some putting forth arguments that they are all different things. Others lamenting the problems of not having a consistent terminology. A few delve into philosophical arguments.

A paper from 2014 is still relevant today because the arguments haven’t abated. This paper discusses historical, methodological and philosophical aspects. It’s a long paper, probably best suited to academics. It covers just about every aspect of the issues. It also draws in the ICF (International Classification of Functioning, Disability and Health) and international standards which is quite useful. 

The title of the paper downloadable from ResearchGate says it all, Universal design, inclusive design, accessible design, design for all: different concepts—one goal? On the concept of accessibility—historical, methodological and philosophical aspects.

Editor’s Note: I also wrote on the topic of terminology in relation to housing design, Calling a Spade a Shovel: Universal, accessible, adaptable, disabled – aren’t they all the same? 

Abstract: Accessibility and equal opportunities for all in the digital age have become increasingly important over the last decade. In one form or another, the concept of accessibility is being considered to a greater or smaller extent in most projects that develop interactive systems. However, the concept varies among different professions, cultures and interest groups. Design for all, universal access and inclusive design are all different names of approaches that largely focus on increasing the accessibility of the interactive system for the widest possible range of use. But, in what way do all these concepts differ and what is the underlying philosophy in all of these concepts? This paper aims at investigating the various concepts used for accessibility, its methodological and historical development and some philosophical aspects of the concept. It can be concluded that there is little or no consensus regarding the definition and use of the concept, and consequently, there is a risk of bringing less accessibility to the target audience. Particularly in international standardization the lack of consensus is striking. Based on this discussion, the authors argue for a much more thorough definition of the concept and discuss what effects it may have on measurability, conformance with standards and the overall usability for the widest possible range of target users.
