With HoloLens, Microsoft May Just Reinvent Personal Computing
While the first iteration of the HoloLens will almost certainly be both limited and expensive, the technology could very well redefine personal computing.
What is it and how does it work? You can see objects in the world because light that bounces off those objects eventually reaches your eye. Your brain does a bunch of complicated things with this incoming light, ultimately constructing the image that you see in front of you. The HoloLens essentially tricks your brain, sending light into your eye in such a way that the holograms that the device produces appear to exist in the physical world.
The HoloLens itself is a stand-alone computer. Unlike VR headsets like the Oculus Rift, which require a high-end PC in order to function, the HoloLens has its own CPU, GPU, and what Microsoft calls a holographic processing unit, which is likely responsible for all of the calculations necessary to create the holograms. No firm launch date has been announced for the device, but based on the demos shown at E3, the HoloLens appears to be nearly ready to go.
