Abstract

Public reporting burder for this collection of information is estibated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burder to Department of Defense, Washington Headquarters Services, Directorate for Information Operations and Reports (0704-0188), 1215 Jefferson Davis Highway, Suite 1204, Arlington, VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. PLEASE DO NOT RETURN YOUR FORM TO THE ABOVE ADDRESS. HEA), provides high-fidelity NVG imagery required to support effective NVG training and mission rehearsal. Acquisition of a multichannel NVTS, to drive both an out-the-window (OTW) view and a helmet-mounted display (HMD), may exceed resources of some training units. An alternative could be to add one channel of NVG imagery to the existing OTW imagery provided by the ?legacy? system. This evaluation addressed engineering and training issues associated with integrating a single NVTS HMD channel with an existing legacy system. Pilots rated the degree of disparity between the HMD and OTW scenes for various scene attributes and effect on flight performance. Findings demonstrated the potential for integration of an NVTS channel with an existing legacy system. Latency and terrain elevation differences between the two databases were measured and did not significantly impact system integration or pilot ratings. When integrating other legacy systems with NVTS, significant disparities may exist between the two databases. Pilot ratings and comments indicate that (a) display brightness and contrast levels of the OTW scene should be set to correspond to real-world, (b) unaided luminance values for a given illumination condition; disparity in moon phase and position between the two sky models should be minimized; and (c) star quantity and brightness in the OTW scene and the NVG scene, as rendered on the HMD, should be as consistent with real-world conditions as possible.

Perceptual Issues in the Use of Head-Mounted Visual Displays

“…80, 165). Anderson, Vrana, Riegler, and Martin (2002) evaluated several types of head-tracking systems for use with night vision training. Inertial head trackers were recommended for enclosed areas where the placement of additional sensors is not possible.…”

Training for Night Operations - Research Challenges and Opportunities

“…Because only simulated imagery is presented to trainees in simulate approach training environments, dynamic range effects for any night environment may be rendered in the simulated NVG imagery; the dynamic range limitations of projectors become a moot point. Significant research in physics-based simulation led to development of the Night Vision Training System (NVTS) [8] which was enabled by the SensorHost system [9] that performed all physics and NVG-specific computations for the IG. NVTS was successfully demonstrated in an F-16C training simulator at Air Force Research Laboratory in 2003.…”

The Human Factors of Night Vision Goggles

“…A technique that is used to simulate environmental factors is to have a terrain board model with both natural and cultural lighting to demonstrate various illumination conditions (e.g., Folaron, Deacutis, Hegarty, Vollmerhausen, & Schroeder, 2007; Ruffner et al, 2004; Theleman et al, 2008) and special programs to simulate weather effects (e.g., Folaron et al, 2007; Theleman et al, 2008). One of the challenges includes the computational and hardware resources to provide high-fidelity simulation of both the out-of-the-window world and the NVG image (e.g., Anderson, Vrana, Riegler, & Martin, 2002; Clark, Colbert, Pribadi, Riegler, & Anderson, 2005).…”
