Abstract
Abstract The paper first presents a discussion of non-linearities in human sequential behaviour-in terms of interleaving-and then introduces the concepts which underlie non-linear phonology. The paper does not provide a full treatment of the theory of non-linear phonology, nor of its generalization to cover non-speech activities-these can be found elsewhere in the literature. The significance of the formalism of non-linear phonology for researchers and designers in human-computer interaction is revealed through the discussion of several examples, ranging from general behaviour with a multi-tasking interface, via interleaved activities in the use of a note-taking aid, to programming itself.
