When soldiers look through the sights of their assault rifles with the Elbit System's new artificial intelligence data platform, their view is transformed to resemble a first-person shooter video game. Shooters push buttons on a grip to toggle among layers of information about their surroundings, including motion detection, range, ammunition levels and more data that's just a click away. ARCAS, which the Israel-based company is featuring at the DSEI conference in London, incorporates a microcomputer in the weapon to process data and provide a graphical user interface to display the information in the rifle's electro-optical sight and through an optional helmet-mounted eyepiece. The demo used ARCAS systems mounted on M-4s, with testers shooting at stationary targets. The use of ideas from the gaming world is clear when putting the sight up to the eye.
