Abstract. Much attention has been paid in HCI to techniques for designing systems that conform to the tasks users wish to carry out. It is often the case that such approaches rely on identifying the combinations of commands a user will be expectedto issue and information thay will need to access,and designingan interface with appropriate temporal behaviour. Many fields of activity, however, are highly information intensive, and the way in which a human-machine cognitive system makes inferences and reasons and makes decisions is far more important that the way it carries out actions. In this paper, therefore, we explore an approach to design that places much more emphasis on the form and structure of a display than it's temporal properties, and the role it plays in cognitive activity.
