Effective, effectual, accessible. To my way of thinking these three terms mean the same thing, and in reality were going to be talking about accessibility. However, you should be thinking of accessibility in more general terms; the more general terms of effective or effectual use. This is because the concept of accessibility is much broader than the narrow confines of disability it is often associated with.

'Effective Use' -- or 'success in enabling the user to produce a desired or intended result.' In this case we're going to look at barriers to interfaces, interactions, and systems and the engineering principles and practices to counteract those barriers (including Expert Audits). We will finish with an introduction to your second piece of coursework.

Why Not Just Accessibility? You could conventionally think of this as accessibility. Accessibility connotations of disability. I don’t hold with this – access/accessibility is much broader than disability.
