“…An important finding from sensor offset studies was that misalignment of the HMD and sensors could lead to spatial disorientation and possibly compromised navigation (Melzer and Moffitt, 2007), so care was taken to ensure that the helmet mounted display mount was aligned with the sensors to better than 0.5°, thus eliminating any visible mismatch when simultaneously looking at objects through the system and with the unaided eye. To maintain alignment, it was necessary to provide a mechanism that allowed 3-axis translational adjustments, but which prevented any rotational movement.…”

The development of an advanced ground soldier's integrated headgear system for the Army's Future Force Warrior Program passed a major milestone during 2006. Field testing of functional headgear systems by small combat units demonstrated that the headgear capabilities were mature enough to move beyond the advanced technology demonstration (ATD) phase. This paper will describe the final system with test results from the three field exercises and will address the strengths and weaknesses of the headgear system features, head mounted sensors, displays and sensor fusion.

“…These include schemes based on image source, image display technology, visual presentation mode, and optical design approach. [3][4][5] For the purpose of this paper, classification by presentation mode is the most germane, and three categories are used ( Figure 1): monocular, biocular, and binocular. For our discussion, monocular means a single source of HMD imagery is viewed by a single eye; biocular means the HMD provides two visual images from a single sensor, and each eye sees exactly the same image from the same perspective; and binocular means the HMD provides two visual images, one for each eye, from two sensors displaced in space, thus providing perspective.…”

Driven by the operational needs of modern warfare, the helmet-mounted display (HMD) has matured from a revolutionary, but impractical, World War I era idea for an infantry marksman's helmet-mounted weapon delivery system to a sophisticated and ubiquitous display and targeting system that dominates current night warfighting operations. One of the most demanding applications for HMD designs has been in Army rotary-wing aviation, where HMDs offer greater direct access to visual information and increased situational awareness in an operational environment where information availability is critical on a second-to-second basis. However, over the past 40 years of extensive HMD development, a myriad of crashworthiness, optical, and human factors issues have both frustrated and challenged designers. While it may be difficult to attain a full consensus on which are the most important HMD design factors, certainly head-supported weight (HSW), exit pupil size, field-of-view, image resolution and physical eye relief have been among the most critical. A confounding factor has been the interrelationship between the many design issues, such as early attempts to use non-glass optical elements to lower HSW, but at the cost of image quality, and hence, pilot visual performance. This paper traces how the role of the demanding performance requirements placed on HMDs by the U.S. Army aviation community has impacted the progress of HMD designs towards the Holy Grail of HMD design: a wide field-of-view, high resolution, binocular, full-color, totally crashworthy system.

A portable head up display (HUD) using the optical combiner lens with a 0.47inch LCD panel for a portable multi-windows virtual display is proposed. The proposed system consists of several micro panels, optical devices, and RGB 3in1 light-emitting diodes (LED) for making the full color display, and video and audio format for the high definition multimedia interface (HDMI) for the connecting between HUD and mobile phone. The multi-windows HUD is designed as an alternative to conventional built-in type HUD targeting the mass volume aftermarket at an affordable price.
