The feasibility of the Fiber-Optic Helmet-Mounted Display (FOHMD) concept has been demonstrated on a breadboard system installed on a simulator at the Air Force Human Resources Laboratory (AFHRL). Behavioral and engineering evaluation are currently being conducted to determine the optimum design specification for an Engineering Prototype scheduled for completion in late 1984. This paper describes the significant engineering aspects of the FOHMD together with the exploratory program for improving its performance. (Author).

The briefing covers the capabilities, current status and future plans of the Fiber Optic Helmet Mounted Display (FOHMD) being developed under a joint US/Canada cost-sharing program. The technology is intended to fill a gap that exists in simulator visual displays. The technology is not classified and has been briefed a number of occasions throughout the simulation industry. This briefing was given previously to the joint US/Canada Working Group who supports this project. It contains a pictorial description of the design concept, a table of training requirements versus display performance, the current status of the development effort, recognized technical problems with improvements underway to eliminate them, and an anticipated schedule for demonstration. The briefing follows the viewgraphs and describes their intent in slightly more detail.

Wide field of view, high resolution, detailed visual displays are cruical for the effective simulation of complex air-to-air and air-to-ground combat environments. Current dome and dodecahedron systems are far to costly and lack the combination of required capabilities. The Air Force Human Resources Laboratory (AFHRL) is currently developing a fiber optic helmet mounted display (FOHMD) system which has the potential for filling these demanding requirements. The breadboard FOHMD, built through a Canadian cost-sharing contract with CAE Electronics, displays a head-slaved high resolution area of interest surrounded by a low resolution background in color. The instantaneous field of view is comparable to the view available to a pilot when wearing an Air Force helmet. Four image generation channels and projectors are used to generate individual displays for each eye. The imagery is piped to the helmet via coherent fiber optic bundles. This system is a valuable research tool for studying many of the issues associated with helmet mounted displays such as image stability, resolution/brightness/field of view trade-offs, and visual perception/fatigue.

Here's an in-depth, design practitioner's study of helmet-mounted display and sight technology (HMD/HMS). This unique combination of advanced optics, computing, and electronics gives users a continuous, hands-free display of computer, 3-D, or virtual imaging. Authored by a leading aerospace engineer, Helmet-Mounted Displays and Sights takes a comprehensive look at this increasingly popular technology -- from the human factors associated with the use of HMDs, to design requirements of HMD/HMS, to new and future advances in image source and display technology, and more.

This report details the development of a fiber-optic-coupled helmet-mounted display. A working breadboard model has been developed. A computer-generated image projected from a light valve is relayed to the input of a large format coherent fiber-optic bundle. The fiber-optic bundle transfers the image to a set of helmet-mounted optics which display the imagery via two in-line, wide-angle infinity displays. The helmet position and attitude are sensed and used to control the image content. Studies were also conducted on requirement for eye-slaved control of image content.

Target detection, motion detection, and flight performance were compared under conditions of 25 and 45 binocular overlap using only the low resolution background channels of a Fiber Optic Helmet Mounted Display (FOHMD). In experiments 1 and 2, eight experienced fighter pilots viewed aircraft targets which either approached ownship or moved vertically in the field of view, respectively, at various angles of off axis eccentricity. As an additional task, pilots flew the system as an air combat simulator and were required to track, engage, and destroy an airborne target. The results indicated target and motion detection and binocularly displayed targets were superior to that of monocularly displayed targets. There was no significant difference in target detection or motion detection between the two overlap conditions, per se, nor between left and right fields of view. In both overlap conditions, performance was degraded within 5 of the lateral edges of the field of view, and suppression was evident in contralateral fields in the areas of optical frame overlap. However, the latter effects were combined nearer the central viewing area for the 25 deg overlap condition. No significant differences were noted in the supplementary air combat task as a function of overlap, but structured debriefing data indicated loss of target imagery was less of a problem with the larger overlap. It was concluded that greater than 25 deg binocular overlap should be utilized in follow-on systems. (Author).
