Tech companies REALLY want to get futuristic headgear off the ground. Google had its ill-fated Google Glass experiment, Facebook dropped $2 billion of the Oculus Rift virtual reality headset, plenty of other companies are working on VR headsets as well, and even Mini wants to give you glasses that let you see through your car.
The one that really excites me, though, is Microsoft's HoloLens. Microsoft dropped this bombshell of a gadget earlier this year, and it's still the coolest thing going.
As a refresher, HoloLens is a standalone headset that you put on your head, letting you look through clear high-definition screen lenses. It's essentially a computer with its own CPU, graphic processing unit and the brand new holographic processing unit.
That means it can understand the world around you and overlay holographic information. You can see a calendar on the wall, games come to life in the living room, you can look inside a car engine and tons more. It also includes spatial sound so you can "hear" holograms that might be behind you.
Microsoft did a good job showing off what HoloLens could do when it was announced, and you can click here for my coverage of that event. However, it just launched a new demo at its recent Build conference, and you have to see it to believe it.
