''The headgear system will incorporate sophisticated display technology via development of nanotechnology materials. For example, highly ordered carbon nanotube arrays will be used to create a Field Emission Visor Display for the future Soldier. This type of display will have very high resolution due to the large number of effective pixels created by the array. Onboard processing will "warp" (i.e., intentionally distort the image or arrange the pixels) the image to match the curvature of the visor. The viewing angle will be extremely wide (~180 degrees). Energy consumption will be very low, thanks to the large number of emitters and the resulting large emission current (high luminance efficiency) at low power input. The headgear system will also have 360-degree situational and environmental awareness through the exploitation of onboard sensors (a single, 360 degree, hyper-spectral helmet-mounted sensor that provides images that are visually registered with the visor display/Soldier viewing angle) and organizational sensor fusion (remote sensors, UAVs, satellite, imagery link to command centers).
