Requirements that involve the usability of systems can be properties of interactions rather than systems alone. We demonstrate this proposition by means of four examples and then suggest how a notation like CSP may be used to provide a framework for considering different modelling approaches. Interaction requirements that related to multi-windowed systems, walk up and use systems and dynamic systems such as power stations are considered. The paper shows how models provide different representations into which advice from the different disciplines of human computer interaction may be applied.
