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.
