Abstract

An abstract architecture for the design of user-computer interfaces is described. It is intended to serve the user-oriented principles of learnability and usability. The primary interface features selected as responsive to these principles are task-specific context presented to the user, reinforced by system adaptability to user needs. Both of these features are undergirded by interface system modularity. Context is defined to include not only high-level direction and step-by-step guidance toward task completion but also intelligent advice on the different user actions and commands. A prototype interface system was implemented, using a Xerox 1108 LISP workstation and a VAX 11/780 UNIX system as the target computer. It was organized around the definition of a multi-phase interaction event flowchart and is very dependent on object-oriented and rule-based paradigms. Limited test results indicate a favorable performance pattern.
