%X <p>The chapter explores the role that formal modelling may play in aiding the visualisation and implementation of usability with a particular emphasis on experience requirements in an ambient and mobile system. Mechanisms for requirements elicitation and evaluation are discussed, as well as the role of scenarios and their limitations in capturing experience requirements. The chapter then discusses the role of formal modelling by revisiting an analysis based on an exploration of traditional usability requirements before moving on to consider requirements more appropriate to a built environment. The role of modelling within the development process is re-examined by looking at how models may incorporate knowledge relating to user experience and how the results of the analysis of such models may be exploited by human factors and domain experts in their consideration Ambient and mobile systems are often used to bring information and services.</p>
