Microsoft's smart goggles for the US military failed most elements of a recent Army test and one tester remarked the device would be dangerous for soldiers to wear, according to excerpts from an Army report dictated to Insider.Testers also found that the soldiers' field of view including peripheral vision is limited while the headset is on, and the bulk and weight of the device restricts a soldier's movement.While headsets like Microsoft's HoloLens are widely considered key to the metaverse vision promoted by leaders like Meta CEO Mark Zuckerberg, they've struggled to find commercial success.Within Microsoft, there's been widespread strategic confusion in the mixed reality division, talent has defected to rivals like Meta, and a recent leadership shakeup has left the business fragmented."We (Microsoft) are going into the event expecting negative feedback from the customer," the employee wrote on in a memo to members of the company's military contract team, including AI and mixed reality general manager David Marra."
