An Architecture for Intelligent Interfaces: Outline of an Approach to Supporting Operators of Complex Systems

TLDR

The paper proposes a comprehensive support system architecture for operators of complex systems. The architecture includes information management, error monitoring, and adaptive aid functions built on an operator model that blends algorithmic and symbolic components, as illustrated by functional block diagrams. The study identifies several challenging design issues and outlines ongoing efforts to address them.

Abstract

The conceptual design of a comprehensive support system for operators of complex systems is presented. Key functions within the support system architecture include information management, error monitoring, and adaptive aiding. One of the central knowledge sources underlying this functionality is an operator model that involves a combination of algorithmic and symbolic models for assessing and predicting an operator's activities, awareness, intentions, resources, and performance. Functional block diagrams are presented for the overall architecture as well as the key elements within this architecture. A variety of difficult design issues are discussed, and ongoing efforts aimed at resolving these issues are noted.
