This paper describes a new concept for interfacing operational decision makers with their information systems. It is intended to overcome the rigidities of current architectures by enabling the decision maker to direct, modify, and manipulate the presentation of information in real-time through a highly automated interface system. The current practice of specifying a decision maker's desires to a programmer, who must in turn produce a data gathering and formatting program that interfaces with some graphics system, is unsatisfactory for the real-time needs of an ever-changing decision environment.An experimental Information Presentation System has been implemented utilizing a high-level knowledge representation language. The system manipulates general descriptions of information presentation concepts such as coordinate systems, trnasformations, display regions, display objects, and the relationships between data objects and their depictions. This paper summarizes the current state of that system and the Information Presentation System concept.
