A Google Glass test model rests on a dummy Airman at the 711th Human Performance Wing at Wright-Patterson Air Force Base, Ohio. Engineers and software designers with the Wing's Battlefield Air Targeting, Man-Aided Knowledge, or BATMA(N) group, here are currently testing Google Glass for possible use by battlefield Airman. The goal is to improve operators' situational awareness by allowing them to access real-time information through a hands-free, see-through heads-up display.
