请问HN：有没有人在工业中使用增强现实、虚拟现实、眼镜、头盔等设备？
自从2012年谷歌眼镜首次亮相以来，围绕增强现实及相关技术在工业中的应用产生了相当多的热议，预计这将提升工人的生产力和能力。
然而，我在各个行业中看到的实际应用却寥寥无几。我本以为，至少能够获取免提信息（例如蓝图、说明书、笔记等）、进行视频聊天和通话以分享视角等功能，对于许多行业来说会非常有用。目前似乎在美国国防（IVAS）和塞尔维亚的医疗远程监测中，确实有一些有趣的试点项目涉及到Hololens。
你知道有哪些相关的例子或应用案例吗？或者你自己是用户吗？你认为目前面临的障碍是什么——实际的实用性、显示质量、成本，还是其他因素？

Since Google Glass made its debut in 2012, there's been a fair amount of hype around augmented reality and related tech coming into its own in industry, presumably enhancing worker productivity and capabilities.<p>But I've heard and seen so little use in any industries. I would have thought at a minimum that having access to hands-free information retrieval (e.g. blueprints, instructions, notes, etc), video chat and calls for point-of-view sharing, etc would be quite useful for a number of industries. There do seem to be interesting pilot trials involving Hololens in US defense (IVAS) as well as healthcare telemonitoring in Serbia.<p>Do you know of any relevant examples or use cases, or are you a user yourself? What do you think are the hurdles - actual usefulness, display quality, cost, something else?
