Microsoft's biggest reveal during today's Windows 10 event was Project Hololens, a wearable visor that will insert holograms into a person's field of vision. If their hype video is to be believed, it's going to be just the thing to make Minecraft completely immersive. And completely inescapable.
The presentation from today's event showed a video that highlighted Microsoft's ambitious goals for Hololens, which basically amounted to a real world with interactive holograms overlaid on top of it. Interacting with Minecraft was one of the uses shown for Hololens. Implementation like this is probably years away but it sure looked cool.
