Abstract
Human-computer interaction (HCI), and much other behaviour, can usefully be thought of as a continuous process of cyclic interaction with the environment. The action someone takes leads to changes to the state of the world. These are evaluated with respect to, and in a manner conditioned by, the user's current goals. This evaluation leads to the reformulation of goals and further action, leading to a new state of the environment, and so. A state-transition model that makes explicit the relationship between user and environment at each stage of interaction is developed that leads to two further representations: (i) the state-transition scenario describing a particular trajectory through the state space; (ii) the state-transition framework defining classes of state-transition model with empirical consequences. Display-driven cyclic models have received considerable attention in the recent HCI literature. One state-transition framework, corresponding to a class of these models, is shown to be inadequate as a theory of human-computer interaction.
