I know someone who worked on a heads up display for paramedics. People have been trying to make these for a few years. Just think how complicated it actually is for a nurse: - it's got to supply actually useful information that isn't fairly trivial to get by picking up a chart - it'll have to hook up with some sort of input device - are they carrying around the AR device and the input device at all times? - it's got to be wearable for 8 hours or it's completely pointless (you can't use it half the time if it's essential) - it's got to be light and durable - for almost every hospital it'll have to have specialized software written to integrate - an amazing UI to use it without touching anything as they can't keep cleaning their hands to use it - there's got to be total network coverage in every hospital room, it can't cut out in wi-fi deadspots (I have no idea how good this usually is) And those are the easy problems I can think of without any particular domain experience. I imagine it will get a lot more complicated when you know what they actually do.
