The future of augmented reality is here today or at least (as of this writing) in early development. If you have the skills to develop 3D computer applications, you can buy the Microsoft Hololens Development Edition online and, while it will cost you an arm and a leg and probably a kidney, it will let you write code that will project holograms straight on the real world through the lenses of a rather heavy headset. Even if you don't want to write code, there are apps already available, just not a lot of them. Microsoft's promotional material makes it look as though this gadget will turn your visual world into a magic land of dancing bots and elves (and maybe someday Pokemon), but early testers claim that its field of view is limited, with holograms only appearing in a portion of it, and that there are still some bugs to be worked out. Still, if you want to see the future before the future has happened, these magic lenses could give you a glimpse of things to come. And maybe let you participate in making it happen.
Early on, Microsoft is pitching this device for use in the workplace, where it can project assembly instructions directly on the objects to be assembled. But it could be the forerunner of game machines that will let you play first-person shooters using your own backyard as the battleground. (Note: Using real guns is not advised.) Reviewers have described the Hololens as more of a moonshot than a galactic tourmobile, so it's not for casual users yet, but you'll probably figure that out when you look at the price tag. Owners complain that the headset is bulky enough to give you a headache and probably a neck ache with prolonged use. You'll need WiFi nearby to connect it with software.
If you want a pair of lenses that's lighter in weight and ready right now for industrial use, try the Epson Moverio BT-200, which will show you how to repair appliances without having to look at the manual. Or if you just want to play virtual reality games, you're better off sitting at your computer with an HTC Vive or Oculus Rift.
Minecraft is pretty much real life with this. It Is awesome.
I also struggled to get HoloLens to fit every time I put it on. I had to regularly re-tighten, re-situate and realign the headgear.
Once you move your head and walk around to see the holograms from different angles, your mind will start to feel like there are virtual objects all around you.
Holograms only appear in a small section of your vision. It is uncomfortable after extended periods.
The gaze and spatial tracking are fantastic and the experiences currently available will give you insights into the immense possibilities for this platform.
