Abstract
The paper describes how the identification of 'status-status mappings' early in the specification and design of an interactive system can highlight potential temporal problems in the interface. These problems arise because without infinitely fast computation and communication, any constraints between status in the interface are bound to be violated some of the time. This violation will at best be a slight lag between the source of a change and its display and at worst may lead to inconsistency between parts of the interface. We identify the ways in which status-status mappings are violated and the way in which they are mediated by events in the implementation of a system. This enables the designer to control the eventual behaviour of the system and avoid the worst pitfalls.Keywords
