The Integrated Soldier System Project (ISSP) is the cornerstone of Canada's future soldier modernization effort, which seeks to "significantly enhance tactical level individual and team Lethality, Mobility and C4I performance in the complex, network-enabled, command-centric, effects-based digitized battlespace." This capital acquisition project is supported by a number of R&D Technology Demonstration Projects within Defence R&D Canada. Several of these projects focus on the human factors aspects of future technologies, such as IR sensors. The Soldier Information Requirements Technology Demonstration (SIREQ TD) project examined the performance impact of NVGs, LWIR imaging systems, and fused systems (both optical and digital fusion) on target detection, recognition and identification. NVGs were shown to provide good identification performance while LWIR systems excelled in detection tasks. Fused systems show promise of augmenting the respective stand alone capabilities of each sensor type, but more work is required to optimize fusion algorithms. The Soldier Integrated Headwear Technology Demonstration (SIHS TD) project is looking at the human factors aspects of mounting a range of vision enhancement sensors on a helmet, including optimal placement of both sensors and displays with respect to center of mass, total head borne weight, and visual offset and parallax issues. Overall headwear system weight should be less than 2.5 kg, and if an offset from the eye is required then a horizontal offset (vice vertical or oblique) of the sensor appears most acceptable. These findings have implications on the design of future IR and fused sensor systems for dismounted soldiers.

“…Performance was best when the stereoscopic display was used in conjunction with other informational displays regarding hovering performance. In a ground navigation task using night vision goggles (NVGs), CuQlock-Knopp, Torgerson, Sipes, Bender, & Merritt (1995) showed that binocular NVGs were better than either biocular or monocular NVGs. On a teleoperative robotic driving task, Chen, Oden, Drexler, & Merritt (2010) found that 3D displays improved performance over 2D displays.…”

“…Monocular: Monocular NVGs (such as AN/PVS-14; left image in Figure 6.4) has a single objective lens, a single amplifying tube, and a single eyepiece. The user of a monocular device sees a single image with the intensified visual scene with only one eye, whereas the second eye, when not closed, has an unaided view of the world (e.g., CuQlock-Knopp, Sipes, Bender, & Merritt, 1996;CuQlock-Knopp, Torgerson, Sipes, Bender, & Merritt, 1995;Ho & Tang, 2004). Biocular: Biocular NVGs (such as the AN/PVS-7; middle image in Figure 6.4) also has a single objective lens and tube but two eyepieces.…”

The technology underlying night vision goggles (NVGs) enhances human ability to operate in dark and low-light conditions. However, NVG-aided vision is limited relative to daylight human vision and may entail risks. This review focuses on NVGs with image intensifier technology and explores the impact of their use on human performance. The review covers technology and device characteristics (image quality and field of view), physical configuration (ocular configuration, NVG weight, and forward center of gravity), and contextual and environmental factors (mission and task aspects, lighting, weather, and terrain). The key human factors in NVG use are visual and cognitive performance (visual acuity and contrast sensitivity, stereopsis and depth perception, distance and size estimation, spatial orientation, and situation awareness), and physical and physiological aspects (neck strain and injuries, and headaches). Understanding technology and contextual factors and their influence on human factors is critical to improving performance and safety with NVGs. Technology and device improvements, along with appropriate mission planning and training, play a critical role in aided night vision performance. INTroDuCTIoN Vision is the most dominant perceptual sense and requires adequate lighting to be effective. Yet there is often a need to operate in inadequate lighting circumstances. Many military missions and tasks are performed in poor light conditions and in the dark because it affords better concealment and surprise. In addition, numerous civilian operations and occupations take place in poor lighting conditions: search and rescue, law enforcement (police, border control, surveillance, etc.), hunting, wildlife observation, and many more. In most of those circumstances, people aim to perform in poor light conditions as well as they would in the daytime. However, although humans have developed exceptional day vision, they nevertheless have poor night vision. There is a real need, therefore, for technologies to enhance vision in low-light circumstances.
