Unsurprised at the feedback, the idea that wearing your monitor on your head will improve things isn't enough for the majority of use cases.
What I'd like to see is some of the technologies used moved into markets where having information directly at hand is critical.
For example, A&E, being able to call (with prior consent) someone's medical records, their current observations, and intelligent warnings about someone's condition could offer a big help.
Another area would be car windscreens, merging in some of the self driving car's sensors into a HUD to improve road and hazard visibility, particularly at night when the glare of oncoming headlights can make it difficult.
AR and VR technologies definitely need to stop and think about the use cases before they release and develop the hardware, it's not enough to release hardware and hope someone invests time into it
