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)
This paper builds on an existing model of human-computer interaction that focuses on the information structures employed as distributed information resources by users in deciding how to act. Such resources are not limited to internal mental constructs, but may be distributed between the single user and their environments, as representations in artefacts or(More)
Organisational context is now accepted as a central concept in attempts to understand error in human-machine systems. However, accounts which emphasise the processes of everyday organising, such as accountability and work activity, are needed in order to establish organisational requirements for design. In this article, we provide a framework for the(More)
