Available in PDF, EPUB and Kindle. Book excerpt: Aircrews have reported significant problems in depth perception and distance estimation with night vision goggles (NVGs). The purposes of this experiment were to develop a methodology for quantifying distance estimation abilities with NVGs and to examine the value of a simple training procedure as a means of reducing errors. Absolute distance estimates were obtained from eight male aviators using Aviators Night Vision Imaging System (ANVIS) AN/AVS-6 NVGs before and after exposure to a set of known distances. The results revealed that distance estimates were linear and significant reductions in errors and variability followed exposure to the training procedure. The results are discussed within the context of previous research. Issues for future research are addressed. Distance estimation, Night vision goggles, Training.

Available in PDF, EPUB and Kindle. Book excerpt: Night-vision goggles (NVGs) and, in particular, the advanced, helmet-mounted Aviators Night-Vision-Imaging System (ANVIS) allows helicopter pilots to perform low-level flight at night. It consists of light intensifier tubes which amplify low-intensity ambient illumination (star and moon light) and an optical system which together produce a bright image of the scene. However, these NVGs do not turn night into day, and, while they may often provide significant advantages over unaided night flight, they may also result in visual fatigue, high workload, and safety hazards. These problems reflect both system limitations and human-factors issues. A brief description of the technical characteristics of NVGs and of human night-vision capabilities is followed by a description and analysis of specific perceptual problems which occur with the use of NVGs in flight. Some of the issues addressed include: limitations imposed by a restricted field of view; problems related to binocular rivalry; the consequences of inappropriate focusing of the eye; the effects of ambient illumination levels and of various types of terrain on image quality; difficulties in distance and slope estimation; effects of dazzling; and visual fatigue and superimposed symbology. These issues are described and analyzed in terms of their possible consequences on helicopter pilot performance. The additional influence of individual differences among pilots is emphasized. Thermal imaging systems (forward looking infrared (FLIR)) are described briefly and compared to light intensifier systems (NVGs). Many of the phenomena which are described are not readily understood. More research is required to better understand the human-factors problems created by the use of NVGs and other night-vision aids, to enhance system design, and to improve training methods and simulation techniques.

Book excerpt: The incorporation of technology into aviation has been exponential. Advancements in microelectronics, stealth technology, engine design, and electronic sensors and displays have converted simple aircraft into formidable flying machines. In this book, recognised experts in aviation helmet-mounted displays (HMDs) summarise 25 years of knowledge and experience in the area of HMD visual, acoustic, and biodynamic performance, and user interface issues such as sizing, fitting, and emergency egress.
Download or read book Tactical Display for Soldiers written by Panel on Human Factors in the Design of Tactical Display Systems for the Individual Soldier and published by National Academies Press. This book was released on 1997-01-31 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.

Book excerpt: "The U.S. Army Research Institute for the Behavioral and Social Sciences (ARI) held a formal In-House Researcher Colloquium on 20 November 1997 in Alexandria, Virginia. The main purpose of the colloquium was to provide an opportunity for cross-unit discussion among ARI's more junior researchers. The eight researchers who presented research findings at the colloquium represented ARI's Armored Forces Research Unit, the Automated Training Methods Research Unit, the Fort Leavenworth Research Unit, the infantry Forces Research Unit, the Organization and Personnel Resources Research Unit, the Rotary-Wing Aviation Research Unit, the Selection and Assignment Research Unit, and the Simulator Systems Research Unit. Each research topic was specifically selected by the Research Unit Chief as an example of the best of research being performed at the unit. This report provides brief summaries of the research and biographies of the researchers. It also serves as an example of the range of behavioral and social science research being addressed by in-house researchers at ARI as well as of the backgrounds of ARI's research staff."--DTIC.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental demonstration was made of the efficacy of immediate feedback in improving observers' estimates of distance where those estimates were made outdoors at night while wearing night vision goggles (NVGs). Initially, observers made unguided estimates of distances between marked positions in an open field. Those distances ranged from 25 ft to 210 ft. Later, the same observers made more estimates. After each, they were told the measured distance between the positions. During this training, the observers' eye height from the ground plane was either at a standing position or at an elevated position (12 ft from the ground). After the training--either immediately after, or after a week, or at both times--observers made unguided estimates of distance again. These estimates of ground distance made with the NVGs were significantly improved from the first unguided estimates; average improvement for the group of observers persisted for at least one week after training. direct feedback training appears to be more effective at improving performance at distance estimation (in terms of both precision and error variability) than the training assessed in previous experiments where no verbal feedback was given.
