When the pace of interaction with a task is too slow, the user's execution/evaluation loop is broken. Feedback normally says what has happened. However, when the task is slow, nothing has happened yet - the interest shifts to what will have happened. This poses two problems for the user. Firstly, recalling the appropriate context when a response eventually arrives. Secondly, maintaining the expectation that the response will come and when, so that appropriate action can be taken if it fails to materialise. The design question is how to support these activities, of which the latter has received little emphasis to date.
