Battling with reality

摘要

Augmented-reality displays - that enhance a user's view of the world with useful information on everything from an assailant's body temperature to the velocity of an incoming missile - have been a staple of science fiction movies for decades. But thanks to recent technological advances and reductions in * cost driven by an emerging consumer market, the capabilities of augmented reality (AR) and virtual reality (VR) technology are increasingly catching up with the Hollywood vision. And in the world of defence, where an uncertain world is driving a host of complex operational and training requirements, VR and AR tools are becoming increasingly useful and important. Virtual reality technology has actually been used by the defence industry as a training tool for some time. Indeed, back in 1980 the US Army enlisted experts from gaming firm Atari to develop a training system for its Bradley fighting vehicle based on the firm's vintage Battlezone shoot-em-up.
