Imagine looking left and the old BBC micro keyboard pops up in VR right into your FOV.Valve/HTC will be announcing a "VR" keyboard soon. You heard it here first. Works with the new integrated camera and a positional tracking. Basically the camera tracks your fingers (blue "ghost" fingers as seen through the Vive) with an in app "overlay" of a positionally tracked keyboard. It brings real world objects, in this case a keyboard, into apps/games/etc.
