Microsoft has indeed opened 'the next chapter' in the company's timeline. Along with the release of Windows 10 RP, the Project Spartan and Cortona, Microsoft has also revealed HoloLens, its first venture into the virtual reality arena that boasts of excellent competing devices, like the Oculus Rift, Sony's Morpheus, and Samsung's Gear VR headset. HoloLens is the world's first virtual reality computing platform. All Windows apps can be placed in a virtual, 3D world, so that it brings user interaction to a brand new level. This is done using a technique called augmented reality in which virtual, 3D entities can be placed in the real world. By the way, HoloLens is the world's first untethered VR device - it comes without any annoying wires or connections. Hence it is a complete device in its own right, without the need to connect to even a PC through a wireless mode. The HoloLens boasts of its own processor, with a holographic processing unit, and runs Windows 10. Microsoft even secretly partnered with NASA to help understand holographic computing better with the some aid from Mars Rover. So, check the weather while you work, snap while you commute, and play games anywhere without having to carry a power source and huge head mounted projectors. This is really a very good spec compared to Oculus Rift and Morpheus, which are required to be connected to your desktop computer or Playstation respectively. And Gear VR headset just works with the Samsung Galaxy Note 4. Phil Spencer was quoted by Engadget, "I've always applauded Oculus for what they've created. I think this is something different." Microsoft said that Windows 10 will come bundled with the HoloLens API, for Windows app developers so that they can create products with awesome VR. But currently HoloLens is still very far from a market release right now. Plus Microsoft hasn't revealed what it would cost. But what Microsoft has shown about HoloLens till now looks amazing. We look forward to its launch.
