Proceedings of the Workshop UXEM'09 (Interact 2009), 1-4.
Abstract. Bevan's careful distinction between usability (effectiveness + efficiency + satisfaction per ISO 9241-11) and the broader notion of "user experience" added in ISO 9241-210. Argues that UX is the larger category, with usability as one of its components alongside hedonic / aesthetic / emotional response.
