Microsoft's HoloLens headsets are giving US Army testers nausea

Microsoft's HoloLens headsets for the US Army have some teething troubles. Bloomberg and Insider say a recent unclassified report reveals the current Integrated Visual Augmentation System (IVAS) iteration is creating problems for soldiers in tests. Some testers suffered nausea, headaches and eyestrain while using the augmented reality goggles. Others were concerned about bulk, a limited field of view and a display glow that could reveal a soldier's position even at long distances.
