Hololens is a whole new Technology from Microsoft. It brings Science fiction to Science fact - creating a whole new world for us.

HololensMicrosoft HoloLens is made up of specialized components that together enable holographic computing. The optical system that works in lock-step with advanced sensors. The HPU(Holographic Processing Unit) that makes light work of processing a large amount of data per second. All those components and more enable you to move freely and interact with holograms.

Hardware

Microsoft Hololens hardware is Designed in such a way that the weight distribution is made perfect. It protects your nose and ears from unnecessary weight and let you do your work with ease.
Hololens is strong and yet a light weight device as it contains more computing power than an average Laptop. With no wires and external wires you can move freely and create your own world.
The Capabilities of a Hololens:
  • Sensor Fusion : Microsoft HoloLens has advanced sensors to capture information about what you're doing and the environment you’re in.
  • Advanced Optics : Holographic high-definition lenses use an advanced optical projection system, generating multi-dimensional full-color images with very low latency so you can see holograms in your world.
  • Holographic Processing unit : The HPU is custom silicon that processes a large amount of data per second from the sensors. Microsoft HoloLens understands gestures and where you look, and maps the world around you, all in real time.

Develop

With Microsoft hololens learn how to build Universal apps. The Build Attendees at Microsoft Hololens Conference realized that the Hololens will change the way of work. Work done with Hololens would be better and more passionate. 
Developers used the Programming tools and found them easy and impactful.
By the new Developing Tools you can create Apps just not for one Platform but all the technologies with Windows 10. 
The Developers that weren't able to make it to the Build can watch the events and Sessions about Hololens here
