How far away is the hardware? I think AR is truly the next evolution in human-computer interaction, but every time I explore the hardware it still seems like an entirely immature area. We haven't even really reached the "Palm Pilot" stage as I like to call it. In that stage the Hardware and Software are production ready and usable but only power users are truly interested in it. There's HoloLens, there's Google's attempts, there's those glasses by that company called North. All of those are nowhere near mainstream ready. There's heads up displays which are interesting and I think have lots of opportunities. I think realistically we need a proper set of glasses with a solid brain-computer interface in order for AR to take off and become a mainstream. I personally don't want to try interacting with a pair of smart glasses using a hand-held controller or some motion detection sensors.
