Available in PDF, EPUB and Kindle. Book excerpt: A review of the night vision goggle (NVG) literature published over a 30-year period was conducted to identify NVG training issues that should be addressed to enhance the performance of ground forces. First-, second-, and third-generation image intensification devices are covered. Although the focus is on ground forces, research that addressed aviation issues is also included. The review documents bow soldier performance has improved from advancements in image intensification technology as well as from concerted efforts to address some long-standing training problems. Training research and development issues identified are: determining techniques to train soldiers on NVG technology and its application to night tasks, how to train soldiers to integrate NVGs with other equipment, training to enhance distance estimation abilities of soldiers when using NVGs, and training to improve mounted and dismounted navigation skills with NVGs. Attention must also be paid to developing training techniques that will enable soldiers to overcome the learning plateaus and human factors problems with NVGs so they become truly skilled at night with NVGs.

Available in PDF, EPUB and Kindle. Book excerpt: "This research examined the capabilities of virtual environments to simulate night vision goggle (NVG) effects. Different solutions for simulating NVG images were assessed. Two conditions simulated NVGs but used different software approaches. Two additional conditions simulated unaided night environments that required soldiers to wear NVGs. Four-man infantry teams conducted urban operation missions under each condition. Objective assessments were obtained on the number of events correctly detected and the average time required to detect an event. Subjective assessments of task difficulty and image fidelity were also made. No significant differences were found across night conditions for either event detection or time. Significant differences in task difficulty ratings occurred for movement, visual detection, and maintaining situation awareness. In general, tasks were more difficult to perform while wearing the NVGs compared to simulated versions of NVG images. Soldiers also ranked the conditions involving actual NVGs as more realistic. The unique contribution of virtual environments for night operations training may be at the entry level. However, specific image fidelity issues associated with the use of NVGs in simulated unaided night environments must be addressed if this approach is to be used as an effective training medium."--Stinet.

This book was released on 1995-10-31 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fighting at night has become increasingly important to combat success as new and better generations of night equipment allow soldiers to see and operate more effectively at night. The goal of the NIGHTFIGHTER program being executed by the Infantry Forces Research Unit (IFRU) of the U.S. Army Research Institute for the Behavioral and Social Sciences is to improve soldier, leader, and unit training for night operations. Research under NIGHTFIGHIER encompasses a broad spectrum of skills and issues, ranging from basic skills which do not require special equipment to the specialized skills demanded by the most sophisticated night technologies. and from training issues which have persisted over time to those emerging as night operations become more common. The research reponed here is on an instructional program which emphasizes basic unaided night vision knowledge and skills. Through the use of35-mm slides with neutral density filters, students experience what happens to their vision at night and learn techniques to overcome visual problems encountered at night. The program was developed under separate Memoranda of Agreement with the Naval Aerospace Medical Research Laboratory and the Naval Aerospace and Operational Medical Institute. The report presents a series of experiments conducted by the IFRU which showed the program increased the proficiency of experienced soldiers, as well as Infantry trainees, and can be presented effectively by military instructors. Research findings on the unaided night vision program have been presented to the command group at the U.S. Army Infantry Center and to all Army agencies which supponed the research. The program has been demonstrated to the observer/controllers and the opposing force at the Joint Readiness Training Center (JRTC), to the command group of the 82d Airborne Division, to the Ranger Training Brigade, and to numerous visilors 10 the U.s .

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: The third-generation image intensification technology in night vision goggles (NVGs) used by ground forces provides at best 20/40 or 20/45 visual acuity. These acuity levels cannot be achieved unless soldiers adjust their NVGs properly. Documentation available to soldiers does not address optimum adjustment techniques developed by the aviation community nor does it address what can be used in the field to achieve a good setting. We examined the effectiveness and utility of 15 different objects commonly available to soldiers to determine which provided the best visual acuity readings with the AN/PVS-713 NVGs. After training and practice acuity improved by 25% over the baseline assessment. No large differences in readings occurred among the objects. However, a more definitive picture emerged when the average readings were combined with measures of variability and soldier preferences. The initial recommendation is to use one of the following objects for NVG adjustment: trec trunk, vehicle, vehicle trail, stars, blue chem light, or an infrared chem light. Not recommended are bright and/or red light sources, white paper, and trees silhouetted against the night sky. Problems in assessing acuity with NVGs are also discussed.

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.

Download or read book The Effect of Future Forces Warrior Planned Sensor Offset on Performance of Infantry Tasks written by and published by . This book was released on 2006 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to evaluate the effect of offsetting the sensors in digital night vision goggles (NVGs) (thermal and image intensification [I2] sensors) from the eye. In addition to the digital prototype goggles, an enhanced NVG (ENVG), which optically combined thermal and I2 capabilities, was used as a baseline device. The experiment was executed over a period of a week with five groups of Soldiers, each of which contained six Soldiers acting as participants. Soldiers received familiarization training about the two prototype night vision devices (NVDs) and the baseline device, and they were briefed at the start of each exercise to explain what was required of them during the event. The exercises included a wide range of infantry activities to enable comprehensive assessment of features. These included grid location exercises, individual movement techniques (IMT) course trials, cross-country woodland patrols, target laser trials, and aim light mounting trials. The experiment was conducted in October 2005 during hours of darkness at various sites in Fort Benning, Georgia. The prototypes did not perform as well as the baseline in this study on the dismounted tasks. Soldiers preferred the baseline overwhelmingly to either of the prototypes because with the baseline goggle, they could see terrain features much better for navigation and walking, for firing a laser at targets, and for performing close tasks than they could with the prototypes with the offset sensors. The prototype goggles caused the Soldiers to experience problems such as eyestrain and disorientation. It may be that the use of NVGs with offset sensors will cause Soldiers difficulty when they perform dismounted tasks. However, this conclusion cannot be stated categorically because the devices with offset sensors used in this study were prototypes and had other problems that could also have impacted their performance.
