In this paper, we present a new approach to interaction modelling based on the concept of information resource. The approach is inspired by recent distributed cognition (DC) literature but develops a model that applies specifically to human-computer interaction (HCI) modelling. There are of course many approaches to modelling HCI and the motivation of this(More)
THEA is a technique designed for use by interactive system designers and engineers to help anticipate interaction failures. These may become problematic once designs become operational. The technique employs a cognitive error analysis based on an underlying model of human information processing. It is a highly structured approach, intended for use early in(More)
THEA is a technique developed to help designers in interactive systems (originally in the aviation domain, but hopefully applicable in other contexts) to anticipate interaction failures or " human errors " that may be problematic once their designs become operational. The techniques is intended for use early in the development lifecycle, as design concepts(More)
