The device

Before we delve globally into the code, let's first examine what we are talking about. I assume you have the machine somewhere near. If you do not have access to one, I suggest that you try to get it. Although the software we are going to build will run on the emulator, you will find that the experience is below par. It just is not the same as developing your software on a real device. Of course, we will use the emulator quite extensively in real-world scenarios; a typical company will have a team of somewhere between 5 and 15 professionals working on the software. It would be rather expensive to buy a device for all of them. One device per team or maybe two devices per team would be enough to make sure that the software does what it should do and that the experience is as magical as it can be.

Let's examine the hardware for a bit. What are we talking about? What is a HoloLens? What parts does it consist of?

In case you have never seen a HoloLens before, this is what it looks like:
