Microsoft Corp. has an initial $1.3 billion at stake in a test beginning later this month on whether its HoloLens augmented-reality goggles can be turned into an effective combat system for the U.S. Army.

The monthlong test from May 23 to June 17 will be evaluated by the Pentagon’s testing office to determine whether the headset is ready for full production and initial deployment.

The project by the Redmond, Washington-based company aims to develop a "heads-up display” for U.S. ground forces, similar to those for fighter pilots. The Integrated Visual Augmentation System would let commanders project information onto a visor in front of a soldier’s face and would include features such as night vision.
