Microsoft showcased its amazing HoloLens technology at yesterday's Build 2015 conference. The technology and the headset has received a significant update since the last public showing in January. One of the interesting things about HoloLens is that it can be used as a standalone product, unlike other VR headsets this product doesn't need to be connected to a computer.
HoloLens runs universal apps from Windows 10 and is capable of providing an immersive holographic experience that you can interact with. The device turns any surface or even the air itself into a display, you can chec out the videos to get an idea of what the HoloLens can do. In the second video they even demonstrate a virtual dog that follows you around. The device is expected to become available in the "Windows 10 timeframe" and the possibilities really seem endless.
