... The visual display component of the information-processing subsystem is envisioned as a flip-down monocular presentation device mounted to one side of the soldier's helmet. The display proposed for daytime operations is an opaque display that can be used to provide the soldier 1

... ENHANCING THE PERFORMANCE OF INDIVIDUAL SOLDIERS The Army's interest in providing individual, dismounted infantry soldiers with new tactical information systems has been partly motivated by combat experiences in recent conflicts. Specifically, the individual soldier's accomplishment of an assigned mission and his survival appear to be correlated with the amount and quality of information he is provided (Franks, 1994~.

... Military environments are increasingly varied with respect to both their physical aspects and their task conditions. In addition to warfare, military missions include antiterrorist operations, catastrophe relief, and peacekeeping, among other operations.

... As a result, the panel recommends that the Army should proceed in an experimental mode, comparing the positive and negative performance implications of the monocular helmet-mounted display with alternative technologies.2 Moreover, even if the visual issues are resolved, shifting the infantry soldier's attention away from the 2A 1996 report from the General Accounting Office concludes that several human factors issues associated with the Land Warrior System are not yet resolved (U.S. General Accounting Office,

... · Threshold values are needed for screen clutter, gray scale, limits of spatial and temporal resolution, the impact of visual acuity differences in soldiers, shortterm memory limits in processing the information, individual susceptibility to various levels of incapacitation associated with visual rivalry, depth cues, field of view (versus resolution) values, delivery modality preferences and trade-offs, and the impact of attentional narrowing.

... Another area is the combined effects of different levels of physical and mental workload on soldier performance over extended periods of time. · Comparisons of the Land Warrior monocular system should be made with the existing biocular night vision goggles worn by infantry soldiers and the binocular night vision goggles worn by aviators to determine if significant differences in task performance exist.
