The Hypermedia Information System (HIS) is being developed under the auspices of the Federal Aviation Administration (FAA) Office of Aviation Medicine's (AAM) Human Factors in Aviation Maintenance (HFAM) research program. The goal of the hypermedia project is to create new tools and methods for aviation-related information storage and retrieval. The HIS can be used alone as a tool to access information, as well as integrated with training and job aiding systems. A book paradigm is maintained by the HIS reader interface, which consists of two components: a navigation component and a viewing component. A variety of access paths into and within a document are supported: the bookshelf, the outline viewer, hot links, searching, and bookmarks. Successful integration of the HIS into the following tutoring and job aiding systems has been achieved by the FAA: the Environmental Control Systems (ECS) Tutor; the Air Traffic Control Beacon Interrogator (ATCBI) Tutor; and the Performance Enhancement System. The HIS is currently undergoing transition from a proof-of-concept system to a fully functional system capable of supporting the instructional, maintenance, and safety inspection needs of the aviation industry. The next step is to increase its capabilities and to support existing and emerging documentation standards. Contains six references. (MAS)
