FORT KNOX, Ky. (AP) — In a few quick steps, the Booz Allen Hamilton associate has tapped into a mobile application designed specifically for the General George Patton Museum of Leadership. He then scans an icon featuring Patton’s image, affixed to the case, with the phone’s camera.

Within seconds, a three-dimensional image of a pistol appears on the phone’s screen. Pressing against the digital image with his finger, Miller moves the pistol around in different directions to illustrate the benefits of augmented reality and how this technology has gradually permeated the Patton Museum.
