Paper Abstract

Night vision goggles have been in use for many years and limitations in their use have been well studied through training research and flight experience. However, advances in technology have led to improvements in NVG display capabilities and in some cases helmet mounted display (HMD) technology has begun replacing NVG systems. These advances have led to an increase in the complexity of imaged scene content, thus requiring a greater level of cognitive effort for interpretation, especially when compared to the images provided by current NVG systems. In some cases the complexity of visual imagery has resulted in systems not being classified as operationally suitable. This presentation will focus on a few of the problems noted while testing some of these advanced systems. Topics will include: added complexity of imagery in wide-field-of-view (WFOV) NVG systems, effects due to imagery created by sensors displaced from the normal eye position (increased interocular separation), effects due to imagery projected onto seethrough visor designs, and effects resulting from cockpit design/geometry (e.g., location and design of large-format head-down displays, and the position of structures such as window frames). Training concerns and potential mitigation strategies for HMD design concepts will also be covered. The issues discussed are important for manufacturers to understand during the early design phase, and for testers to understand during developmental or operational testing.
