Cognitive networks as a guide to menu organization: An application in the automated cockpit

Abstract: When a menu-driven interface controls information in the domain of expertise of the end users, the difficulty that inexperienced users typically have in accessing the panels they seek can be reduced by making the menu organization consistent with the user's cognitive organization. A general tool for deriving a cognitive network is described and applied to the concepts displayed and controlled on the panels of an interface to a flight management system. The cognitive network was used to select the options that would appear on each panel of three different prototypes. The prototypes differed with respect to the amount of redundancy (extra pathways) between a set of dominating panels that appeared on a primary index page and the remaining panels. A fourth prototype was based on the recommendations of a design team rather than the cognitive network derived from a sample of pilots. Four pilots were assigned to each of the four prototypes, in a training session that required the pilots to find specific...

Helping computers communicate: The Open Systems Interconnection model promises compatibility for a variety of computer systems, although not all its functions are yet defined

Abstract: The possibilities opened up by the Open Systems Interconnection (OSI) model are discussed. It is noted that many of the protocols to implement OSI are now complete, and manufacturers offer products to implement some of the standards. The International Organization for Standardization will continue to expand the functions covered by OSI as new communications network architectures and technologies emerge. Each of the seven layers making up the model is described. Prospects for the model's success are then surveyed.

A Knowledge-Based System for Network Communication Design

Abstract: Networks are the mainstay of modern-day communications. Their use in transporting voice, pictures, and data is constantly increasing. Applications in the areas of computer communications, teleprocessing, and teleconferencing are finding wide markets. The thrust of current research in communication networks is lower costs. Attempts to integrate voice and data, exploit optical fibres and satellite technology, and optimize network topologies and hardware are steps in this direction. This work attempts to apply the current paradigms in Artificial Intelligence research to the problems in network optimization. The experience AI researchers have gained in organizing and using knowledge to solve problems (Ref. 1,2) is especially relevant in this work.
